Detailed Description

The embodiment of the invention provides a drainage system for a bridge deck expansion joint, which is mainly arranged between drainage pipes in two adjacent bridge sections, as shown in figure 1, a first bridge section 1 and a second bridge section 2 are two adjacent bridge sections, the two bridge sections are connected through an expansion joint 3, the relative displacement of the two bridge sections is released through the expansion joint 3, usually, a plurality of vertical drainage pipes are arranged on two sides or one side of a road surface of one bridge section at intervals, if water is accumulated on the road surface, the water flows into the vertical drainage pipes on two sides, and meanwhile, a horizontal drainage pipe is arranged at the bottom of one bridge section, namely, the first drainage pipe or the second drainage pipe in the figure and mainly drains the sewage flowing into the vertical drainage pipes on the road surface.

Referring to fig. 1, generally, due to different structures of two adjacent bridge sections, two drain pipes inside the two adjacent bridge sections are different in height, an end portion of the first drain pipe 4 provided in this embodiment is bent downward, an end portion of the second drain pipe 5 is connected to the water tank 6, wherein the bent downward portion of the end portion of the first drain pipe 4 extends into the water tank 6, and the length of the water tank 6 is long enough, wherein when the bridge body on the left moves left and right relative to the bridge body on the right, the bent downward portion of the end portion of the first drain pipe 4 moves in the water tank 6 and does not move with an inner wall of the water tank 6, so that it can be ensured that water in the first drain pipe 4 can be drained into the water tank 6 and then drained from the second drain pipe 5.

Further, the second drainage pipe 5 in this embodiment is communicated with the bottom of the water tank 6, and a filter screen 11 is arranged in the water tank, wherein the filter screen 11 is arranged between the pipe orifices of the first drainage pipe 4 and the second drainage pipe 5, so that drainage of the drainage pipes between two adjacent bridge floors can be realized on one hand; on the other hand, can filter the waste water of discharging in the first drain pipe through filter screen 11 in the water tank, reduce because of too much debris flow in the jam problem that causes in the next drain pipe, operating personnel can regularly clear away the debris in the water tank.

As shown in fig. 2, the top of the water tank 6 in the embodiment of the present invention includes two first cover plates 7 and two second cover plates 8 butted with each other, wherein a first arc-shaped groove 9 is formed at a position where the first cover plate 7 is butted with the second cover plate 8, and a second arc-shaped groove 10 is formed at a position where the second cover plate is butted with the first cover plate, when the two cover plates are butted with each other, the first arc-shaped groove 9 and the second arc-shaped groove 10 can be spliced to form a sliding groove, the downward bent portion of the first drain pipe 4 passes through the sliding groove, and when the left bridge moves left and right relative to the right bridge, the downward bent portion of the first drain pipe can move right and left in the sliding groove, so that the drain pipe is prevented from colliding with the inner wall of the water tank.

The length of the sliding groove in this embodiment can be determined from the measured displacement of the first bridge section 1 relative to the second bridge section 2.

Further, the water tank 6 at the end of the second drainage pipe 5 is usually arranged at the bottom of the expansion joint between two adjacent bridge bodies, and some expansion joints are not provided with corresponding drainage devices, so that accumulated water on the road surface is carried with sundries left from the expansion joint, and a cover plate is arranged at the top of the water tank to prevent other sundries from entering the water tank.

When the top of water tank set up the apron, in order to make things convenient for take out the debris in the water tank, a side of first apron and water tank is together articulated in this implementation, and the second apron is together articulated with the relative side of water tank simultaneously, like this when the debris in the filter screen is taken out to needs, can open first apron and second apron, then it can to take out debris.

Of course, in other embodiments, the first cover plate 7 and the second cover plate 8 may be directly fastened to the top of the water tank 6 and may be detachable from the water tank 6, when the sundries on the filter screen 11 in the water tank are taken out, the first cover plate 7 and the second cover plate 8 may be detached, and when the sundries are taken out, the cover plates may be covered.

Regardless of the cover plate is opened by rotating and the cover plate is opened by sliding, because the sliding groove is arranged at the butt joint position of the two cover plates at the upper part, and the inner diameter of the sliding groove is far larger than that of the first drainage pipe 4, the drainage of the first drainage pipe cannot be influenced in the dismounting process.

Further, referring to fig. 3 and 4, in this embodiment, two opposite side walls inside the water tank 6 are respectively provided with a clamping groove 12, specifically, an L-shaped plate is horizontally welded and fixed on the side wall of the tank body to form a clamping groove 12 with an open top, and at the same time, a side of the filter screen 11, which is in butt joint with the inner wall of the water tank, is bent downward to form a clamping edge 13, so that when the filter screen 11 is installed, the clamping edge 13 on the filter screen 11 can be directly placed in the clamping groove 12, thereby realizing the fixation of the filter screen 11.

Specifically, referring to fig. 5, the filter screen 11 in this embodiment is a plate with a plurality of through holes on a surface thereof, and the through holes on the surface filter the sewage flowing out of the first drainage pipe.

In order to facilitate taking out the filter net in this embodiment, it is easy for those skilled in the art to know that handles may be installed at both ends of the filter net, so that the filter net may be taken out by lifting the handles upward.

It should be noted that the installation of the filter screen provided by the present invention is not limited to the horizontal state in the embodiment, but also can be an inclined state, so that the sundries flowing out from the first drainage pipe can slide to the relatively lower side along the filter screen to be used for accumulating the sundries, thereby facilitating the taking out of the sundries.

Further, referring to fig. 1, considering that the water tank 6 is usually disposed at the bottom of the expansion joint 3 between two adjacent bridge sections, although the expansion joint 3 is also provided with a corresponding waterproof measure, after a period of use, a water leakage phenomenon usually occurs, so a U-shaped water supporting member 14 is further disposed at the bottom of the expansion joint between two adjacent bridge sections, two sides of the U-shaped water supporting member 14 are respectively connected with the cross sections of two adjacent bridge decks in a sealing manner, so that water leaking from the expansion joint can directly flow into the U-shaped water supporting member 14, and meanwhile, two ports of the U-shaped water supporting member 14 in this embodiment are connected with each other in a sealing manner through a blocking plate, so that the U-shaped water supporting member 14 and the blocking plates at two sides form a water container with an open top.

The bottom of the U-shaped water supporting member 14 is communicated with the inside of the water tank through a water discharge pipe 15, so that the water inside can be guided into the water tank to be prevented from flowing into a river.

It should be noted that, the U-shaped water supporting member 14 in this embodiment is a flexible member, and because two adjacent bridge sections may be due to temperature difference or when the vehicle travels at the top and the relative displacement occurs, the U-shaped water supporting member may also bend along with the bending, and the blocking plates on both sides may also stretch out and draw back or displace along with the bending, so that the water container formed by the U-shaped water supporting member and the sealing plates on both sides is also a flexible member as a whole, and is capable of adapting to the change of the distance between the first bridge body 1 and the second bridge body 2.

In order to adapt to the left and right movement of the U-shaped water supporting member, the water discharge pipe 15 can be arranged as a flexible pipe, and a pipe opening is arranged on the cover plate of the water tank 6, and the water discharge pipe 15 can be inserted on the pipe opening so as to discharge the water accumulated in the U-shaped water supporting member 14 into the water tank 6.

Finally, the embodiment of the invention also provides a bridge body which comprises the drainage system used between the expansion joints of the bridge deck.
