Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high slope local deformation or instability treatment technology, specifically relating to a combined support structure for high slope local deformation or instability. Background Technology
[0002] The treatment of localized deformation or instability of high slopes typically involves the complete excavation and removal of the deformed or unstable body. However, the excavation of deformed or unstable bodies on high slopes often causes a chain reaction of deformation or instability on the slope above the deformed or unstable body. Furthermore, the deformed or unstable bodies on high slopes are generally located at a high elevation, requiring a large amount of excavation and transportation work, and the slope surface usually lacks access for construction, resulting in low efficiency in slag removal and excavation operations. Simultaneously, during the excavation of deformed or unstable bodies, loose gravel or debris sliding down the slope can threaten the safety of personnel, vehicles, equipment, and buildings below the slope. Utility Model Content
[0003] To address the shortcomings of existing technical solutions, this utility model provides a combined retaining structure for local deformation or instability of high slopes, which can effectively solve the above problems.
[0004] The technical solution adopted by this utility model is as follows: a combined retaining structure for local deformation or instability of a high slope, including an active protective net covering the surface of the deformed or unstable body; a retaining wall arranged on the slope walkway below the location of the deformed or unstable body, the retaining wall having drainage holes, and the retaining wall being fixed to the slope by foundation anchors; and a passive protective net arranged on the slope walkway below the retaining wall.
[0005] Furthermore, the length of the retaining wall on the slope walkway is greater than the range of the deformable or unstable body, and it surrounds the deformable or unstable body on its sides.
[0006] Furthermore, the passive protective net arranged on the ramp at the lower part of the retaining wall has a length on the ramp that is greater than the range of the deformable or unstable body, ensuring that the passive protective net can intercept the deformable or unstable body when it partially becomes unstable and falls.
[0007] Furthermore, when the slope is high and there are many horse trails, passive protective nets can be added to other horse trails as needed to increase the safety margin.
[0008] Furthermore, the length and type of the foundation anchor bolts are selected based on the stability of the retaining wall.
[0009] The beneficial effects of this utility model are as follows: Compared with the traditional method of completely excavating the deformed or unstable body to treat local deformation or instability of high slopes, this method causes less disturbance to the slope and reduces the risk of chain deformation or instability of the upper slope of the deformed or unstable body; the combined retaining structure makes full use of the self-weight of the deformed or unstable body to stabilize the slope foot, reducing the amount of excavation and transportation work for the deformed and unstable body; and it reduces the safety risks to personnel, vehicles, equipment, and buildings below the slope during construction. This utility model has a wide range of applications and obvious technical and economic advantages. Attached Figure Description

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0015] like Figure 1 , 2As shown, the combined retaining structure for local deformation or instability of high slopes of this utility model includes an active protective net 1 covering the surface of the deformed or unstable body; a retaining wall 2 arranged on the slope walkway below the location of the deformed or unstable body, with drainage holes 3 on the retaining wall, and the retaining wall is fixed to the slope by foundation anchors 4; and a passive protective net 5 arranged on the slope walkway below the retaining wall.
[0016] Preferably, the length of the retaining wall 2 on the slope walkway is greater than the range of the deformable or unstable body, and it surrounds the deformable or unstable body on its sides.
[0017] Preferably, the length of the passive protective net 5 arranged on the slope walkway at the lower part of the retaining wall is greater than the range of the deformable or unstable body, so as to ensure that the passive protective net 5 can intercept the deformable or unstable body when it partially becomes unstable and falls.
[0018] Preferably, when the slope is high and there are many horse trails, passive protective nets 5 can be added to other horse trails as needed to increase the safety margin.
[0019] Preferably, the length and type of the foundation anchor 4 are selected according to the stability of the retaining wall 2.
[0020] Specifically, taking the implementation of a combined retaining structure for local deformation or instability of a high slope as an example, an active protective net 1 is arranged on the surface of the deformed or unstable body, and a retaining wall 2 is arranged on the slope walkway below the location of the deformed or unstable body. The retaining wall is equipped with drainage holes 3 and foundation anchors 4, and a passive protective net 5 is arranged on the slope walkway below the retaining wall. This utility model does not require the excavation of the deformed or unstable body, reducing disturbance to the slope above the deformed or unstable body and lowering the risk of chain deformation or instability of the slope above the deformed or unstable body; it reduces the amount of excavation and transportation work for the deformed and unstable body of the slope; and it reduces the safety risks to personnel, vehicles, equipment, and buildings below the slope during construction operations.
[0021] This utility model can solve the problems of chain deformation or instability of the upper slope caused by the disturbance of the upper slope during the excavation operation in the overall excavation scheme adopted by the traditional treatment of local deformation or instability of high slopes, the large amount of excavation and transportation of deformed and unstable slope bodies, the difficulty of transporting slag, and the high safety risks to personnel, vehicles, equipment and buildings in the lower part of the slope during the excavation of deformed and unstable bodies.
[0022] This invention minimizes slope disturbance, reducing the risk of cascading deformation or instability above deformable or unstable sections of the slope. The combined retaining structure fully utilizes the self-weight of the deformable or unstable sections to stabilize the slope toe, reducing the amount of excavation and transportation work required for these sections. It also reduces safety risks to personnel, vehicles, equipment, and buildings below the slope during construction. This invention has a wide range of applications and significant technical and economic advantages.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
