In one application scenario, the reinforcement device 10 of the present application is used to reinforce a slope body, wherein the slope body includes an expansive soil slope 20 and a stabilizing body 30. The stabilizing body 30 has an inclined slope, the expansive soil slope 20 is laid on the slope of the stabilizing body 30 to form a slope of the expansive soil slope 20, and a potential sliding surface 40 is formed between the expansive soil slope 20 and the stabilizing body 30 along the slope of the stabilizing body 30. When the expansive soil slope 20 absorbs water and expands, it slides along the latent sliding surface 40 with respect to the stabilization body 30. In particular, the stabilising body 30 may be a stabilising rock mass. The expansive soil side slope is a slope body formed by expansive soil, namely expansive soil, and is cohesive soil which expands violently after being soaked in water and shrinks remarkably after being dehydrated. The expansive soil has strong hydrophilicity and obviously reduced strength after water absorption, thereby causing serious harm to highway engineering and slope engineering.

In one embodiment, referring to fig. 1-7, a reinforcement device 10 includes a bolt structure 100, a frame beam structure 200, an end cap 300, and a damping assembly 400. Specifically, the anchor structure 100 is a steel strand 110 that passes through the potential sliding surface 40. The frame beam structure 200 is disposed at one end of the anchor structure 100, the end cap 300 is sleeved on the other end of the anchor structure 100, and the anchor structure 100 can slide relative to the end cap 300. A damping assembly 400 is disposed between the bolt structure 100 and the end cap 300 for increasing the frictional force as the bolt structure 100 slides relative to the end cap 300. In the protection state, the frame beam structure 200 is laid on the slope surface of the expansive soil slope 20, and the end cap 300 is fixed to the stabilization body 30.

In the using process, the anchor rod structure 100 is fixed on the slope surface of the expansive soil side slope 20 through the frame beam structure 200, the other end of the anchor rod structure is anchored in a stable rock body within the potential sliding surface 40 through the end cover 300, so that the anti-sliding resistance is directly generated on the potential sliding surface 40 through the anchor rod structure 100, the anti-sliding friction resistance is increased, the structure surface is in a compression state, the integrity of the expansive soil side slope 20 and the stabilizing body 30 is improved, the mechanical property of the slope body is fundamentally improved, the displacement of the expansive soil side slope 20 is effectively controlled, the stability of the slope body is promoted, and the purposes of rectifying bedding, landslide, dangerous rocks and dangerous rocks are achieved.

Above-mentioned reinforcing apparatus includes the stock structure and can resist the damping subassembly of certain displacement, and when the slope took place great convergence deformation along the glide plane, the pulling force of stock structure will further increase, makes the pulling force that the damping subassembly took place to slide, and the damping subassembly in-process that slides, the stock structure does not take place to break to the removal through the damping subassembly resists the deformation of country rock, and then improves side slope anti-skidding power and side slope overall stability. When the side slope further slided along potential slip plane, damping component warp too big, surpasss damping component's deformation range, and stock structure is broken, loses and consolidates monitoring effect. The device can not only consolidate the native side slope of inflation through the stock structure before the landslide, can release the effort when the small scale landslide body slides simultaneously in the landslide earlier stage, and then continues to consolidate the native side slope of inflation through the stock structure to the increase reinforcing apparatus can consolidate the deflection of the slope body, improves the reinforcement effect that reinforcing apparatus can.

In one embodiment, referring to fig. 4-7, damping assembly 400 includes a first damping member 410 and a second damping member 420. The first damping member 410 is fixed to an end of the anchor rod structure 100, the second damping member 420 is disposed inside the end cap 300, and the second damping member 420 abuts against the first damping member 410. The friction between the anchor structure 100 and the end cap 300 is increased by the cooperation of the first damping member 410 and the second damping member 420.

In one preferred embodiment, the first damping member 410 includes a first saw tooth portion, and the second damping member 420 includes a second saw tooth portion opposite to the first saw tooth portion in shape and arranged oppositely, so that the first damping member 410 is pressed against the second damping member 420 through the first saw tooth portion and the second saw tooth portion.

Among the above-mentioned reinforcing apparatus, damping subassembly is including locating the first damping part of stock structure tip and the inside second damping part of end cover, prevents the friction loss of stock structure when sliding for the end cover, has realized damping subassembly's the stable connection between stock structure and end cover, has still reduced the installation degree of difficulty of first damping part and second damping part.

In one specific embodiment, first damping member 410 is a damping body and second damping member 420 is a damper. Preferably, the damping body is a friction type damping body.

Specifically, when the expansive soil slope 20 undergoes a small displacement before the slope body is unstable, the tension applied to the anchor rod structure 100 is smaller than the tension which enables the damper to slip, the damper does not move, and at this time, the deformation of the slope expansive soil slope 20 is resisted through the elastic deformation of the anchor rod structure 100. When the slope begins to be unstable, the expansive soil slope 20 is displaced and increased, the expansive soil slope 20 deforms to enable the tensile force borne by the anchor rod structure 100 to be larger than the tensile force enabling the damping body to slide, the damping body slides along the damper on the inner wall of the end cover, the deformation of the expansive soil slope 20 is resisted through the movement of the damping body, and after the damping body displaces, the deformation energy of the expansive soil slope 20 is released, and then the expansive soil slope is in a stable state again. When the slope body is completely unstable, the slope displacement is further increased, the damping body continues to slide along the damper on the inner wall of the end cover, when the anchor rod structure 100 cannot resist the downward sliding force of the expansive soil slope 20 through the friction force generated by the movement of the damping body, the damping body is pulled out of the damper, and the anchor rod structure 100 loses the reinforcing effect. At this time, the total deformation of the anchor rod structure is the stretching length of the anchor rod structure 100 plus the sliding length of the damping body, that is, the total deformation of the anchor rod structure 100 is much larger than that of a common anchor rod, and the effect of resisting the deformation of the expansive soil slope 20 is improved.

In one embodiment, referring to fig. 4-7, the reinforcement device 10 further includes a sensing assembly 500. The sensing assembly 500 is disposed on the anchor rod structure 100, and is configured to measure an axial force of the anchor rod structure 100 and convert the axial force into an electrical signal for outputting, where the axial force is used to represent deformation and displacement of the anchor rod structure 100. Since the slip force of the expansive soil slope 20 is greater than the anti-slip force of the stabilization body 30, which is a sufficient requirement for the slope body to slide, the sensing assembly 500 is disposed in the expansive soil slope 20 to detect the deformation and displacement of the anchor rod structure 100, determine the state of the anchor rod structure 100, and further determine the slip state of the slope body. When the mechanical parameters of the expansive soil soft layer of the expansive soil side slope potential sliding surface 40 are influenced by rainwater infiltration and decline, or the load of the top of the slope is increased, the residual sliding force of the side slope is increased, the axial force of the anchor rod structure 100 is increased, and the sensing component measures and displays the axial force, so that the real-time monitoring of the sliding force under the side slope is realized.

Above-mentioned reinforcing apparatus is through setting up sensing element, can real-time supervision stock structure's axial force, and then obtains stock structure's deformation and displacement according to the axial force to the deformation degree of control slope body has realized inflation soil slope calamity and has consolidated monitoring integrated system, compares and establishes more on phenomenon observation and empirical method in traditional inflation soil slope engineering monitoring method, can realize down the relation between sliding force and the anti-sliding force and carry out direct monitoring. Meanwhile, the change of the internal force of the anchor rod can be continuously monitored when the landslide body slides in a small range, the change trend of the gliding force and the development stage of the landslide are divided and early warned, and the reinforcement and monitoring integrated function is realized.

In one embodiment, the reinforcement device 10 further includes a receiving assembly (not shown), a processing assembly (not shown), and a display assembly (not shown). Wherein, the receiving component is respectively connected with the sensing component 500 and the processing component by signals, and the processing component is connected with the display component by signals. The processing assembly is used for processing the electric signal to obtain a processing result after receiving the electric signal through the receiving assembly, and sending the processing result to the display assembly; the display component is used for receiving and displaying the processing result. In particular, the display component can be a display, and can also be a reading device.

Above-mentioned reinforcing apparatus is through setting up receiving element, processing component and display element, receives the signal of telecommunication that sensing component sent through receiving element, and then handles this signal of telecommunication and sends to the display element through processing component and show, has realized effective processing and visual show to the signal of telecommunication, and then comes out the structural clear show of axial force of stock, has optimized reinforcing apparatus's monitoring result.

Specifically, the reinforcing device deforms when the sliding surface 40 has a sliding tendency by passing the anchor structure 100 through the potential sliding surface 40 of the expansive soil slope 20, and the axial tension of the anchor structure 100 is increased.

Further, according to the axial force of the anchor rod structure 100 measured by the sensing assembly 500, a stress-strain curve of the anchor rod structure 100 is generated, and according to the stress-strain curve, an expansive soil slope 20 monitoring and early warning scheme can be formulated. Specifically, during a slope destabilization process, the stress-strain curve of the anchor rod structure 100 has an ideal elastic-plastic deformation phase. In the elastic phase of the anchor structure 100, a safety phase is intended before 60% of the ultimate tension of the anchor structure 100. After the stress of the anchor rod structure 100 exceeds the value, the displacement observation needs to be enhanced, and whether the deformation of the surface and the deep part of the side slope can be continuously developed is ascertained; when the stress of the anchor rod structure 100 exceeds 80% of the ultimate tensile strength, early warning is carried out, and reinforcement measures are taken in time when the stress of the anchor rod structure 100 reaches the ultimate tensile strength and generates a large deformation stage, so that the safety of the side slope is ensured.

After the length of the string is determined, the variable quantity of the natural vibration frequency can represent the magnitude of the tensile force applied to the string, and an electric signal in a certain relation with the tensile force can be obtained through a corresponding measuring circuit, so that the precision, the sensitivity and the stability of the sensing assembly are improved, and the installation difficulty of the sensing assembly is reduced.
