AI Technical Summary
In the existing technology, when anti-slide piles and geogrids are used alone, they are difficult to meet the protection needs of steep slopes or slopes with poor geological conditions. Anti-slide piles are subjected to complex forces and local stress concentrations, while geogrids have limited anti-slide capabilities, resulting in limited improvement in slope stability.
A combined structure of anti-slide piles and geogrids is designed. The structure uses a connection component between the ground-mounted piles and the movable piles. The outer wall of the ground-mounted piles is equipped with a wall-breaking blade. The wall-breaking blade is used to cut the slope soil to increase the contact area and friction. Combined with elastic connection and claw hook fixing method, a reliable connection between the anti-slide piles and the geogrids is achieved.
It enhances the all-round protection and support system of the slope, improves the stability and protection effect of the slope, provides more construction options, and reduces material costs.

Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0026] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0027] Referring to the drawings Figures 1-4 The anti-slide pile 1 for slope protection of the embodiment in combination with the geogrid 2 comprises the anti-slide pile 1, the geogrid 2 and the connection assembly 3. The geogrid 2 is a common bidirectional geogrid 2 on the market. The geogrid 2 is laid on the surface of the slope to form a protective layer for enhancing the integrity and stability of the slope soil. The anti-slide pile 1 is arranged along the potential sliding direction of the slope and distributed around the geogrid 2 to form a full-range protective support system for the slope. The geogrid 2 and the anti-slide pile 1 are connected through the connection assembly 3 to fully exert the anti-slide effect of the anti-slide pile 1 and the soil reinforcement effect of the geogrid 2 and realize the cooperative protection between them.
[0028] Referring to the drawings Figure 2 The anti-slide pile 1 comprises the ground pile 11 and the movable pile 12. The ground pile 11 is inserted into the slope. The bottom of the ground pile 11 is a conical structure with a taper angle of 30°-45°. The conical structure can effectively reduce the insertion resistance when inserted into the slope soil, so that the ground pile 11 can more smoothly enter the stable soil layer and improve the installation efficiency and stability of the anti-slide pile 1. Threaded holes 112 are formed on the ground pile 11 and arranged along the height direction of the pile. The movable pile 12 is composed of a screw rod 121 and a hand wheel 122. The screw rod 121 is fixedly installed at the center position of the bottom of the hand wheel 122. The screw rod 121 is matched with the threaded holes 112 on the ground pile 11, and the length of the screw rod 121 is greater than the depth of the threaded holes 112, which provides space for the installation of the connection assembly 3.
[0029] Referring to the drawings Figure 2As an optional mode, the outer side wall of the ground pile 11 is fixedly provided with a wall breaking blade 113, the longitudinal section of the wall breaking blade 113 is in a diamond structure or an inverted triangular structure, and the top of the outer side wall of the ground pile 11 is fixedly provided with a handle 114, so as to facilitate the rotation of the ground pile 11 by an operator. In use, the ground pile 11 is first inserted into the slope, then the ground pile 11 is rotated by the handle 114 after the ground pile 11 is inserted to a certain depth, the rotation range is between 120°-150°, the wall breaking blade 113 cuts the soil of the slope, the contact area and friction force between the ground pile 11 and the soil are increased, so as to enhance the stability of the ground pile 11 and the connection strength between the ground pile 11 and the slope.
[0030] Referring to the drawings Figure 3 As an optional mode, the top of the hand wheel 122 is fixedly provided with an inverted U-shaped piece 123. By arranging the inverted U-shaped piece 123, the rotation of the hand wheel 122 and the screw rod 121 is facilitated. After the anti-slide pile 1 is inserted into the slope, the rope can pass through the inverted U-shaped piece 123, so that the plurality of anti-slide piles 1 are connected into a whole, and the overall stability of the anti-slide pile 1 is improved.
[0031] It should be noted that the cross-sectional shape of the ground pile 11 is one of a rectangle, a circle or an ellipse, and the specific shape can be selected according to the geological conditions of the slope and the construction requirements. The surface of the ground pile 11 is provided with a corrosion-resistant coating, the thickness of the corrosion-resistant coating is 1-2 mm, and the material of the corrosion-resistant coating can be epoxy resin or polyurethane, so as to improve the durability of the anti-slide pile 1.
[0032] Referring to the drawings Figure 4 The connecting assembly 3 comprises a connecting ring 31, the connecting ring 31 is sleeved on the screw rod 121, the inner diameter of the connecting ring 31 is greater than the diameter of the screw rod 121, and the difference between the diameters is 2-5 mm. The gap design enables the connecting ring 31 to freely slide and rotate on the screw rod 121, so as to facilitate the adjustment of the position and angle of the connecting assembly 3. The connecting ring 31 is fixedly provided with an elastic member 32, the elastic member 32 can be a spring or a rubber pad, the elastic coefficient of the elastic member 32 is 10-50 N / mm, the outer end of the elastic member 32 is fixedly connected with a claw hook 33, the claw hook 33 is connected with the geogrid 2, so as to realize the reliable connection between the anti-slide pile 1 and the geogrid 2.
[0033] Due to the elastic connection and the claw hook 33 fixing mode, the connecting assembly 3 is not limited to a specific specification or material of the geogrid 2. Whether it is a geogrid 2 with different hole diameters, mesh shapes or different strength bidirectional geogrids 2, reliable connection can be achieved, providing more selection space for construction. In addition, the connecting assembly 3 adopts connecting ring 31, elastic member 32 and claw hook 33 and other components which are common materials, the production process is mature, and the cost is relatively low. Compared with some complex connection structures, the connecting assembly 3 effectively reduces the material cost on the premise of ensuring performance.
[0034] In the technical scheme adopted in this embodiment, the geogrid 2 is first laid on the slope surface to form a protective layer to enhance the integrity and stability of the soil body, and then the ground penetrating pile 11 is inserted into the slope, the conical bottom structure thereof reduces the insertion resistance, so that the ground penetrating pile 11 can smoothly enter the stable soil layer, the plurality of ground penetrating piles 11 are distributed around the geogrid 2, after the ground penetrating pile 11 is inserted into the soil body, the handle 114 is rotated to rotate the ground penetrating pile 11, the wall breaking blade 113 cuts the soil body, the contact area and the friction are increased, and the stability is enhanced, then the connecting ring 31 of the connecting assembly 3 is placed on the ground penetrating pile 11, then the screw rod 121 is used to realize the connection between the ground penetrating pile 11 and the movable pile 12, at this time, the connecting ring 31 is limited, and then the elastic member 32 is used to realize the connection between the claw hook 33 and the geogrid 2, the anti-slide pile 1 and the geogrid 2 are connected, the anti-slide pile 1 and the geogrid 2 are cooperated, the anti-slide function of the anti-slide pile 1 and the soil body reinforcing function of the geogrid 2 are fully exerted, and therefore the slope is effectively protected, the slope sliding is prevented, and the stability and safety of the slope are ensured.
[0035] Finally: the above only preferred embodiments of the present application have been described, and are not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
