Technical Field
[0001] The utility model relates to the technical field of subgrade anti - landslide devices, and specifically relates to a highway subgrade anti - landslide device. Background Technique
[0002] The highway subgrade is the load - bearing main body of the highway. It consists of width, height and slope gradient, and is responsible for bearing its own rock and soil weight, the weight of the road surface and the traffic load. The design and construction of the subgrade are crucial for ensuring the stability and durability of the highway. The subgrade not only bears and transmits the load, but also supports the embankment to ensure the road surface is flat. At the same time, it requires good drainage performance to prevent moisture from damaging the road surface and subgrade.
[0003] In order to ensure the stability and durability of the highway, subgrades are generally built on the highway. Currently, the existing subgrades, although having the function of bearing and transmitting the load.
[0004] However, most of the existing subgrades do not have an anti - landslide structure, resulting in the subgrade being easily affected by the external environment, making the subgrade prone to collapse and landslide, which in turn endangers the subgrade and pavement structures and is not conducive to long - term use. Therefore, a highway subgrade anti - landslide device is proposed to solve the problems raised above. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a highway subgrade anti - landslide device, which solves the problem that most of them do not have an anti - landslide structure, resulting in the subgrade being easily affected by the external environment, making the subgrade prone to collapse and landslide, which in turn endangers the subgrade and pavement structures and is not conducive to long - term use.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A highway subgrade anti - landslide device, including a subgrade and a device substrate, wherein an anti - landslide structure is arranged outside the device substrate;
[0007] The anti - landslide structure includes a sliding rod fixedly connected to the inner side of the device substrate. A slider is slidably connected to the outer surface of the sliding rod. One side of the slider close to the subgrade is fixedly connected with a connecting rod. A fixing block is fixedly connected to the outer surface of the connecting rod. A resisting plate is fixedly connected to the bottom of the fixing block. A threaded hole is opened on the left side of the device substrate. A threaded rod is threadedly connected to the inside of the threaded hole. A knob is fixedly connected to the left side of the threaded rod. A pushing block is fixedly connected to the right side of the threaded rod.
[0008] Further, the inclination angle of the resisting plate is the same as that of the subgrade slope. An anti - seepage net and a clamping block are fixedly connected to one side of the resisting plate close to the subgrade.
[0009] Further, a clamping groove is opened on the side surface of the subgrade. The clamping block is clamped with the clamping groove.
[0010] Furthermore, both the anti-seepage net and the device substrate are made of stainless steel, and the device substrate is L-shaped.
[0011] Furthermore, ground-gripping spikes for enhancing stability are fixedly connected to the four peripheries at the bottom of the device substrate.
[0012] Furthermore, the number of the sliding rods is two, and they are symmetrically distributed inside the device substrate.
[0013] Furthermore, a plug rod and a socket are fixedly connected to the left side of the device substrate, and the outer diameter of the plug rod matches the inner diameter of the socket.
[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0015] 1. For this highway subgrade anti-landslide device, by setting the anti-landslide structure, the abutting plate can continuously abut against the inclined surface of the subgrade, thereby greatly reducing soil erosion, ensuring the structural integrity of the subgrade, and further achieving the anti-landslide effect, thus reducing the influence of the external environment on the subgrade. At the same time, the probability of subgrade collapse and landslide is reduced, which is more conducive to long-term use. Among them, during use, the staff first needs to fix the device substrate to the side of the subgrade. After the fixation is completed, rotate the knob clockwise, and the threaded rod can be rotated and continuously move to the right, thereby driving the push block to approach the subgrade and abut against the slider, so that the slider continuously slides to the right on the outer surface of the sliding rod. Then, through the cooperation of the connecting rod and the fixing block, finally drive the side of the abutting plate to abut against the inclined surface of the subgrade, achieving the anti-landslide effect.
[0016] 2. For this highway subgrade anti-landslide device, through the cooperation of the anti-seepage net, the clamping block and the clamping groove, when the side of the abutting plate abuts against the inclined surface of the subgrade, the clamping block will be embedded into the inner side of the clamping groove, thereby strengthening the stability of the abutting plate by means of clamping fixation. At this time, the anti-seepage net will be located between the abutting plate and the subgrade, and thus, through its own fine mesh holes, cover the inclined surface of the subgrade to reduce the degree of soil erosion.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 3 In this embodiment, a highway roadbed anti-landslide device comprises a roadbed 1 and a device substrate 2, and an anti-landslide structure is arranged outside the device substrate 2;
[0023] The anti-landslide structure includes a sliding rod 3 fixedly connected to the inner side of the device base plate 2, the outer surface of the sliding rod 3 is slidably connected to a sliding block 4, the side of the sliding block 4 close to the roadbed 1 is fixedly connected to a connecting rod 5, the outer surface of the connecting rod 5 is fixedly connected to a fixing block 6, the bottom of the fixing block 6 is fixedly connected to a resisting plate 7, a threaded hole 8 is opened on the left side of the device base plate 2, the inner thread of the threaded hole 8 is connected to a threaded rod 9, the left side of the threaded rod 9 is fixedly connected to a knob 10, and the right side of the threaded rod 9 is fixedly connected to a push block 11. By setting the anti-landslide structure, the resisting plate 7 can be continuously pressed against the inclined surface of the roadbed 1, thereby greatly reducing soil erosion, ensuring the structural integrity of the roadbed 1, and then achieving the anti-landslide effect, thereby reducing the impact of the external environment on the roadbed 1, and at the same time, reducing the probability of collapse and landslide of the roadbed 1, which is more conducive to long-term use.
[0024] When in use, the staff first needs to fix the device base plate 2 to the side of the roadbed 1. After the fixation is completed, the knob 10 is turned clockwise to make the threaded rod 9 rotate and move continuously to the right, thereby driving the push block 11 to approach the roadbed 1 and resist the slider 4, so that the slider 4 continuously slides to the right on the outer surface of the sliding rod 3, and then through the cooperation of the connecting rod 5 and the fixing block 6, it finally drives the side of the abutment plate 7 to resist the inclined surface of the roadbed 1, thereby achieving the effect of preventing landslides.
[0025] Among them, the inclination angle of the bottom plate 7 is the same as that of the inclined surface of the roadbed 1. On the side of the bottom plate 7 close to the roadbed 1, a waterproof net 12 and a clamping block 13 are fixedly connected. A clamping groove 14 is formed on the side surface of the roadbed 1, and the clamping block 13 is clamped with the clamping groove 14. Both the waterproof net 12 and the device substrate 2 are made of stainless steel. The device substrate 2 is L-shaped. Through the cooperation of the waterproof net 12, the clamping block 13 and the clamping groove 14, when the side surface of the bottom plate 7 abuts against the inclined surface of the roadbed 1, the clamping block 13 will be embedded into the inner side of the clamping groove 14, so as to strengthen the stability of the bottom plate 7 by means of clamping fixation. At this time, the waterproof net 12 will be located between the bottom plate 7 and the roadbed 1, and thus, through its own fine mesh, it will cover the inclined surface of the roadbed 1 to reduce the degree of soil erosion.
[0026] Meanwhile, ground-gripping spikes 15 for enhancing stability are fixedly connected to the four peripheries of the bottom of the device substrate 2. By providing the ground-gripping spikes 15, the fixed stability of the device substrate 2 can be ensured.
[0027] In addition, the number of sliding rods 3 is two, and they are symmetrically distributed inside the device substrate 2. An insertion rod 16 and an insertion sleeve 17 are fixedly connected to the left side of the device substrate 2. The outer diameter of the insertion rod 16 matches the inner diameter of the insertion sleeve 17. By providing the insertion rod 16 and the insertion sleeve 17, it is convenient for the staff to splice multiple anti-landslide structures by means of plug-in positioning for use, and thus it is applicable to roadbeds 1 of different lengths, improving the applicability.
[0028] The working principle of the above embodiment is as follows:
[0029] During use, the staff first needs to fix the device substrate 2 to the side surface of the roadbed 1. After the fixation is completed, rotate the knob 10 clockwise, then the threaded rod 9 can be rotated and continuously move to the right, thereby driving the push block 11 to approach the roadbed 1 and abut against the slider 4, so that the slider 4 continuously slides to the right on the outer surface of the sliding rod 3. Then, through the cooperation of the connecting rod 5 and the fixing block 6, finally drive the side surface of the bottom plate 7 to abut against the inclined surface of the roadbed 1, achieving the anti-landslide effect. When the side surface of the bottom plate 7 abuts against the inclined surface of the roadbed 1, the clamping block 13 will be embedded into the inner side of the clamping groove 14, so as to strengthen the stability of the bottom plate 7 by means of clamping fixation. At this time, the waterproof net 12 will be located between the bottom plate 7 and the roadbed 1, and thus, through its own fine mesh, it will cover the inclined surface of the roadbed 1 to reduce the degree of soil erosion.
