Because the concrete is cheap and easily available, the cost of the concrete base 1 prefabricated and formed by using the concrete is more saved.

In addition, the riser 2 and the central shaft 11 are hollow pipes, and after the connection, the cable can pass through the hollow pipes, so that the cable can be protected, and meanwhile, the cable can be used for transmitting waves conducted from the wave attenuation cavity 21, so that the wave attenuation effect is realized. The anti-glare facility 3 is a device that can prevent glare from damaging a human body. The thin film 4 is made of a soft material, has a small thickness and can be wound on other objects, and in the invention, the thin film 4 is wound on the insertion section of the stand pipe 2, so that direct contact between mortar 5 and the stand pipe 2 can be prevented, and further, the effect of protecting the stand pipe 2 can be achieved. The mortar 5 is a mixed slurry formed by stirring liquid and concrete, the mortar 5 is poured into the solid tube hole 18 from a grouting hole 17, and the solidified mortar and the concrete base 1 form a whole; because the mortar 5 has the bonding performance and has the effects of high strength and high hardness after being cured, the concrete base 1 and the vertical pipe 2 can be bonded together after the mortar 5 is cured, and the whole body formed after bonding also has the effects of high strength and high hardness. The bottom plate 7 is a metal plate with a through hole at the center, i.e. the first axial hole 23, and small holes corresponding to the size of the bolts 6 are arranged around the circular hole, i.e. the first bolt holes 22. Because the structure of the bottom plate 9 and the bottom plate 7 are identical, the second bolt hole 24 and the second axis hole 25 on the bottom plate 9 will be described in detail with reference to the bottom plate 7, and the structure thereof will be described in detail with reference to fig. 4, which will not be described in detail herein. The first 8 and second 10 gussets are a metal block used for welding between the riser 2 and the base plate 7, the central shaft 11 and the bottom plate 9. The bottom table 12, the second table 13 and the girdling 14 are the lower end part, the top end part and the middle part on the concrete base 1, the bottom table 12 is a cube, the side length is smaller than the width between road edge stones on two sides of the highway isolation belt, the plan view surface of the second table 13 is circular, and the girdling 14 between the second table 13 and the bottom table 12 is provided with a slope, so that wind resistance and wind leakage can be reduced and the impact force of air flow on the bottom table can be reduced when the bottom table is placed on the ground, and the backfilling is facilitated when the bottom table is buried, and the stability is enhanced.

It should be further noted that the convex rib 15 is a protrusion formed on the concrete plane or vertical surface; the wave elimination hole 16 is a small hole formed on the convex rib 15 and used for wave leakage; the grouting opening 17 is formed in the surface of the second platform 13 and is funnel-shaped and serves as a grouting opening for mortar 5; the solid tube hole 18 is formed in the concrete base 1 and used for containing mortar 5 and matching the mortar 5 to fix the vertical tube 2; the limiting table 19 is used for limiting the depth of the vertical pipe 2 inserted into the concrete base 1; the cable hole 20 is a hole arranged at the bottom of the concrete base 1, and a cable can penetrate from the inside of the cable hole to be electrically connected with the anti-glare facility 3 and can also be used for wave leakage; the wave elimination cavity 21 is used for absorbing and transmitting waves transmitted from other media, and meanwhile, the lower end of the wave elimination cavity 21 is attached to the ground, so that the generation of same-frequency resonance can be avoided due to the difference of density, relative humidity and geological conditions of earth and stones which are objectively present in a road section; screw thread 26 sets up on the male end of riser 2 for it is more convenient when riser 2 is dismantled from concrete base 1, only need to twist riser 2 anticlockwise and can separate with concrete base 1.

It is worth to be noted that the concrete base 1 and the anti-glare facility 3 are installed in a single body, when waves are transmitted from the vertical pipe 2 to the anti-glare facility 3, the waves are firstly transmitted into the upward plate 7 from the vertical pipe 2, the waves are transmitted into the wave dense medium from the wave sparse medium in the process, the waves are firstly consumed in the vertical pipe 2, the waves which are not consumed are weakened compared with the waves which are transmitted into the vertical pipe 2, then the waves which are not consumed are transmitted into the upward plate 7, the upward plate 7 consumes the waves, the waves are transmitted into the bottom plate 9 from the upward plate 7, and similarly, the waves which are not consumed are transmitted into the anti-glare facility 3 from the bottom plate 9, and then the anti-glare facility 3 consumes the transmitted waves; the wave gradually weakens in the process of propagating from the riser 2 to the anti-glare facility 3, and when the wave is transmitted to the anti-glare facility 3, the transmitted wave is already within the receivable range of the anti-glare facility 3; therefore, the damage of resonance waves to the anti-glare facility 3 can be weakened through the single installation of the anti-glare facility 3 and the concrete base 1, and further, the overall safety is ensured and the service life is prolonged.

Further, the rib 15 on the inner wall of the base 12 is provided with a plurality of turns.

It should be noted that when a vehicle runs across the road around the concrete base 1, the vehicle may generate a road vibration wave during the running process, and the road vibration wave may generate an acting force on the anti-glare facility 3 and the concrete base 1, thereby damaging the anti-glare facility 3 and the concrete base 1. If the road surface vibration wave meets the road surface vibration wave with the same frequency in the medium transmission, superposition can be generated, so that the phenomenon of same-frequency resonance can be generated, and stronger wave can be generated. Therefore, in the invention, the plurality of circles of convex ribs 15 are arranged on the inner wall of the bottom platform 11 of the concrete base 1, because each circle of convex ribs 15 is not arranged on the same surface, and each circle of convex ribs 15 is provided with the wave eliminating hole 16, the convex ribs 15 can absorb and refract the road surface vibration wave transmitted from the road surface, so that the transmission direction of the wave is disordered and staggered to offset, further, the natural frequency of the anti-glare facilities 3 with the same specification, material and weight can be changed, the same-frequency resonance phenomenon is weakened, the road surface vibration wave is weakened at the same time, then, a part of the weakened road surface vibration wave is transmitted out from the wave eliminating hole 26, a part of the weakened road surface vibration wave is transmitted to the road surface along the cable hole 20, and the rest part of the weakened wave is. So that the damage of the road vibration wave to the concrete base 1 and the anti-glare facility 3 can be weakened.

It should be noted that the number of turns of the rib 15 is not specifically limited, and is set according to the size of the concrete base 1 in the specific implementation.

Further, a thread 26 is provided on the lower end of the riser 2, a bevel 27 is provided at the upper opening of the cable hole 20, and a chamfer 28 corresponding to the bevel 27 is provided at the end of the lower end of the riser.

It should be noted that the insertion end of the stand pipe 2 is inserted into the concrete foundation 1, so that the bevel 27 and the chamfer 28 are embedded, wherein the bevel 27 and the corresponding chamfer 28 can stabilize the stand pipe 2 and limit the insertion depth of the stand pipe 2. But also is beneficial to the micro-motion adjustment of the vertical pipe 2 and can avoid the slurry leakage gap.

Further, the grouting opening 17, the pipe fixing hole 18 and the cable hole 20 are all concentric with the wave absorbing cavity 21.

It should be noted that the grouting port 17, the pipe fixing hole 18 and the cable hole 20 are all concentric with the wave absorbing cavity 21, on one hand, when the mortar 5 is grouted, the mortar 5 can flow into the pipe fixing hole 18 quickly, so that the mortar 5 can be filled in the pipe fixing hole 18 quickly; on the other hand, the wave-transmitting pipeline can be used for transmitting waves transmitted from the periphery through the pipeline, and the wave-leaking function is achieved.

Further, the grouting opening 17 is funnel-shaped; the inner diameter of the upper part of the grouting opening 17 is larger than that of the pipe fixing hole 18, and the inner diameter of the lower part of the grouting opening 17 is the same as that of the pipe fixing hole 18; the riser bore inner diameter 18 is larger than the riser 2 outer diameter and the riser 2 inner diameter is larger than the cable bore 20 inner diameter.

It should be noted that the inner diameter of the upper part of the grouting opening 17 is larger than the inner diameter of the solid tube hole 18, so that the mortar 5 can be ensured to flow into the solid tube hole 18 from the grouting opening 17; the inner diameter of the lower part of the grouting opening 17 is the same as that of the pipe fixing hole 18; the mortar 5 is prevented from being accumulated at the contact part of the grouting opening 17 and the solid pipe hole 18, and the solid pipe hole 18 cannot be completely filled. The inner diameter 18 of the solid tube hole is larger than the outer diameter of the vertical tube 2, so that the vertical tube 2 can be inserted into the solid tube hole 18, and a certain gap is reserved between the outer wall of the inserted vertical tube 2 and the inner wall of the solid tube hole 18, and the vertical tube 2 can be adjusted in the solid tube hole 18 conveniently and filled with mortar 5. The inner diameter of the stand pipe 2 is larger than that of the cable hole 20, so that the stand pipe 2 is prevented from passing through the cable hole 20, a limiting effect is achieved, and mortar 5 is prevented from flowing into the cable hole 20.

Further, the first gusset 8, the second gusset 10, the first bolt hole 22, and the second bolt hole 24 are each provided in plural numbers.

It should be noted that the first and second gussets 8, 10 can be used to reinforce the strength and stability between the riser 2 and the base plate 7 and the central shaft 11 and the base plate 9, and to fix the position of the base plate 7 and the base plate 9. The first bolt hole 22 and the second bolt hole 24 can be matched with the bolt 6 to connect the central shaft 11 with the stand pipe 2, and the central shaft 11 is welded on the anti-glare facility 3, so that the anti-glare facility 3, the central shaft 11 and the stand pipe 2 can be connected after the central shaft 11 is connected with the stand pipe 2.

In the present invention, the number of the first gusset 8, the second gusset 10, the first bolt holes 22, and the second bolt holes 24 is not particularly limited, and is set in accordance with the size of the bottom plate 9 and the bottom plate 7. The number of the first gusset plate 8 and the first bolt hole 22 is 4, respectively, as an example in the present invention, wherein the first gusset plate 8 and the second gusset plate 10 have the same structure, and the first bolt hole 22 and the second bolt hole 24 have the same structure, as shown in fig. 4.

Further, the second table 13 further includes a hook hole 29. The hook hole 29 is a through hole formed in the surface of the second platform 13, and is used for loading, unloading, and hoisting. When the weight of the concrete base 1 is too heavy and the installer is difficult to move, a crow bar can be used to pass through the hook opening 29 to move the placing position of the concrete base 1, so that the concrete base 1 is placed horizontally.

When the concrete base 1 needs to be placed on the ground, the method for installing the single concrete base can be as follows; firstly, determining the installation position of the road middle isolation belt, processing the ground on which the concrete base 1 is arranged to be flat, manually carrying or hooking the hook hole 29 of the concrete base 1 by a hook to place the concrete base 1 at the installation position, ensuring that the concrete base 1 is horizontally placed and ensuring that the height of the concrete base 1 is consistent with that of the adjacent concrete base 1. Then, the vertical pipe 2 is penetrated into a first axial hole 23 of the lower plate 7, and the penetrating part of the upper end of the vertical pipe 2 has the same thickness as that of the lower plate 7; then, the thread 26 at the lower end of the outer wall of the riser 2 and the tail end of the lower end of the riser 2 are wrapped by the film 4, the lower end of the wrapped riser 2 is inserted into the solid tube hole 18 in the concrete base 1 from the grouting opening 17 of the second concrete base 13, and the chamfer 28 at the lower end of the riser 2 is embedded with the bevel 27 at the upper end of the cable hole 20 in the center of the limiting table 19; then, the mortar 5 is prepared, and the prepared mortar 5 is injected from a grouting opening 17 to ensure that the mortar 5 fills the gap between the outer wall of the vertical pipe 2 and the pipe fixing hole 18; before the mortar 5 is not solidified, adjusting the verticality of the vertical pipe 2, positioning the vertical position of the vertical pipe 2 by using a gravel or leveling support, and after the mortar 5 is completely solidified, butting the bottom plate 9 to the elevation plate 7 at the upper end of the vertical pipe 2, and enabling the first bolt hole 22 and the second bolt hole 24 to be completely butted, so as to ensure that the first axial hole 23 and the second axial hole 25 are completely butted; then, bolts 6 are used for penetrating into first bolt holes 22 on the bottom plate 7 and second bolt holes 24 corresponding to the first bolt holes on the bottom plate 8, and then the bolts 6 are fastened to finish the installation of the wave absorbing cavity single concrete base installation structure.

When the concrete base 1 needs to be buried, the method for installing the single concrete base can also comprise the following steps: firstly, determining the position of a concrete base 1 to be installed, digging a pit with a certain depth on the ground at the position, processing the pit bottom to be flat, then placing the concrete base 1 in the pit, ensuring that the concrete base 1 is horizontally placed, and ensuring that the height of the concrete base 1 is consistent with that of the adjacent concrete base 1. Then, backfilling the excavated earth and stones until the beam waist of the concrete base 1 is completely buried, and tamping the backfilled earth; or, cement mortar 5 can be poured to fix the concrete base 1 in the pit. The subsequent installation steps are the same as those in ground placement, and are not described herein again.

It is worth to say that, first of all, the concrete base of the invention has simple structure, light weight, can stack and transport in multiple layers, thus can reduce the cost of transportation and installation, and the bottom of the concrete base is set as the square, when putting to the ground, four sides land steadily, compare with the prior art concrete base bottom is circular, under the prerequisite of the same girth, the area of the bottom of the concrete base as the square is smaller, thus reduce the labour intensity. And secondly, the concrete base is provided with a lifting hook hole, and a crow bar or other tools can be used for penetrating through the lifting hook hole, so that the concrete base can be moved more easily and conveniently. Moreover, the beam waist arranged on the concrete base has a certain gradient, on one hand, when the concrete base is buried, the backfill soil can be tamped when the beam waist is buried, so that the friction force between the backfill soil and the concrete base is increased, and the stability of the concrete base is further enhanced; on the other hand, when the concrete base is arranged on the ground, the waist can play a role in wind leakage, the friction force between wind and the concrete base is reduced, the impact force between the wind and the concrete base is reduced, and the stability and the service life of the concrete base are further improved. In addition, the concrete base is installed in a monomer laying type or buried type, cannot be connected with adjacent facilities and is in a monomer state, and therefore when waves are transmitted into the concrete base, the concrete base cannot generate dynamic wave influence on the adjacent facilities.

It is worth to be further explained that longitudinal vibration waves of the road surface can be absorbed and eliminated through the wave elimination cavity, the wave elimination hole and the convex rib which are arranged in the bottom of the concrete base, the natural frequency of the plate bodies with the same shape, material and weight is changed, the generation of same-frequency resonance is avoided, and therefore the service life of the concrete base is prolonged. In addition, the lower end of the vertical pipe is provided with threads and is wrapped by a film, and when the vertical pipe is maintained and disassembled in the later period, the vertical pipe can be separated from the concrete base by only rotating the vertical pipe out anticlockwise, so that the operation is simple and convenient, and the maintenance is convenient.
