Description

Technical Field

[0001] The present application relates to the technical field of geological disaster management, and in particular to a rail pile retaining wall protection structure. Background Art

[0002] Rail piles are a type of anti-slide piles and are often used to reinforce steep slopes or areas with poor geological conditions where collapse or landslides may occur. They are especially commonly used in the reinforcement of large landslides and the slopes of large open-pit mines.

[0003] When setting rail piles, it is necessary to first drill holes at the preset positions of the slope, and then place the old rail piles in the holes. The bottom of the rail piles should be placed in the thrust direction of the landslide. After the rail piles are set, concrete is poured into the space between the rail piles and the inner wall of the borehole, so that the rail piles are fixedly connected to the rock in the borehole through the concrete, thereby completing the reinforcement of the slope. Rail piles are widely used in slope reinforcement projects due to their advantages such as lightness, flexibility, and ease of construction.

[0004] However, the actual construction conditions of civil engineering projects are complicated. Sometimes the soil of the geotechnical structure is too soft, and weather conditions such as rainy days make the soil of the geotechnical structure more prone to slope sliding. At this time, even if the slope is installed with rail piles, the slope is still prone to slope sliding, which has an adverse effect on the road surface near the slope. Utility Model Content

[0005] In order to improve the strength of the reinforced slope and reduce the situation where the reinforced slope is still prone to slippage due to bad weather or soil factors, the present application provides a rail pile retaining wall protection structure.

[0006] The present application provides a rail pile retaining wall protection structure, which adopts the following technical solution:

[0008] A plurality of rail piles, wherein the rail piles are fixedly connected to the geotechnical structure at the bottom of the slope, the plurality of rail piles are integrally formed with a retaining wall, and a first positioning portion is fixedly connected to a side wall of the rail pile;

[0009] An abutment plate, the abutment plate being fixedly connected with a plurality of second positioning portions, and the abutment plate being sleeved on the first positioning portions;

[0010] A plurality of steel mesh sheets, wherein the steel mesh sheets are arranged between two adjacent rail piles, and the steel mesh sheets are inserted into the first positioning portion and the second positioning portion;

[0011] A locking portion, wherein the locking portion is disposed on the first positioning portion and is used to tightly abut the contact plate against the rail pile.

[0012] By adopting the above technical solution, the wire mesh is inserted into the first positioning part and the second positioning part, and then the abutment plate is set on the side of the wire mesh away from the rail pile, and the locking part is used to press the abutment plate against the rail pile, so as to fix the wire mesh to the rail pile. The wire mesh can connect multiple rail piles as a whole, thereby improving the strength of the retaining wall, and the wire mesh can increase the contact area between the protective structure and the slope, thereby improving the strength of the reinforced slope and reducing the situation where the reinforced slope is still prone to slip due to bad weather or soil factors.

[0013] Optionally, the second positioning portion includes a shell, a driving portion and a plurality of first spring sheets, wherein the plurality of first spring sheets are fixedly connected to one end of the shell, the driving portion is slidably connected to the shell, and the driving portion is used to drive the plurality of first spring sheets to deform in a direction away from each other at the same time.

[0014] By adopting the above technical solution, after the wire mesh is inserted into the second positioning part, the driving part is moved, so that the driving part drives the multiple first spring pieces to deform in the direction away from each other at the same time, so that the multiple first spring pieces are pressed against the holes on the wire mesh, thereby reducing the shaking of the wire mesh when casting the retaining wall. The multiple second positioning parts can limit the freedom of the wire mesh at multiple points, thereby further improving the strength of the protective structure.

[0015] Optionally, the driving part includes a slider and a plurality of supporting parts, the plurality of supporting parts are arranged around the slider, and an elastic member is connected between the supporting parts and the slider.

[0016] By adopting the above technical solution, the elastic member is compressed and deformed before the driving part moves, and the elastic member recovers its deformation after the driving part moves, so that the multiple support parts move away from each other at the same time and abut against the first elastic sheet, thereby causing the multiple first elastic sheets to deform away from each other at the same time.

[0017] Optionally, the shell is provided with a slide groove, the inner wall of the slide groove is provided with a snap-in groove, the slider is slidably connected to the inner wall of the slide groove, the slider is provided with a snap-in block, and the snap-in block is used to snap-in with the snap-in groove to lock the slider and the shell.

[0018] By adopting the above technical solution, when the slider moves, the clamping block can be inserted into the clamping groove, so that the slider is clamped to the housing, thereby fixing the slider to the housing.

[0019] Optionally, the sliding block is fixedly connected to a second elastic piece, and the clamping block is fixedly connected to the second elastic piece.

[0020] By adopting the above technical solution, the second spring piece can be deformed, so that the clamping block can move inside the slide groove.

[0023] Optionally, the retaining wall is provided with a drainage pipe, the drainage pipe runs through the retaining wall, and one end of the drainage pipe is located on a side of the retaining wall close to the slope.

[0024] By adopting the above technical solution, the drainage pipe can lead the water of the slope to the other side of the retaining wall, thereby reducing the accumulation of water inside the slope at the retaining wall.

[0025] Optionally, a drainage channel is provided in the geotechnical structure below the retaining wall.

[0026] By adopting the above technical solution, the drainage channel can collect water flowing out of the drainage pipe and divert the water away, thereby reducing the accumulation of water at the bottom of the retaining wall.

[0027] Optionally, a support foot is integrally formed at the bottom of the rail pile.

[0028] By adopting the above technical solution, the support legs can be consolidated with the rock and soil structure, thereby improving the stability of the fixation of the rail piles to the rock and soil structure.

[0029] Optionally, a connecting rod is rotatably connected to the bottom of the rail pile, and the connecting rod is fixedly connected to a reinforcement part.

[0030] By adopting the above technical solution, when the rail pile is lowered, the reinforcement part naturally droops under the action of gravity, so that the reinforcement part abuts against the bottom wall of the borehole. Then the rail pile is further lowered, so that the rail pile moves, and the reinforcement part rotates at the same time, and then concrete is poured between the inner wall of the borehole and the rail pile. At this time, the connecting rod and the reinforcement part can play the role of steel bars in the reinforced concrete structure, thereby improving the reliability of the rail pile fixation and improving the strength of the protective structure.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. The wire mesh is inserted into the first positioning part and the second positioning part, and then the abutment plate is set on the side of the wire mesh away from the rail pile, and the abutment plate and the rail pile are pressed tightly with the locking part to fix the wire mesh to the rail pile. The wire mesh can connect multiple rail piles as a whole, thereby improving the strength of the retaining wall, and the wire mesh can increase the contact area between the protective structure and the retaining wall, thereby reducing the situation of slope landslide;

[0033] 2. After the steel mesh is inserted into the second positioning part, the driving part is moved so that the driving part drives the plurality of first spring pieces to deform in a direction away from each other at the same time, so that the plurality of first spring pieces are pressed against the holes on the steel mesh, thereby reducing the shaking of the steel mesh when pouring the retaining wall.

[0034] 3. The drainage pipe can lead the water from the slope to the other side of the retaining wall, thereby reducing the phenomenon of water accumulation inside the slope at the retaining wall;

[0035] 4. When the rail pile is lowered, the reinforcement part naturally droops under the action of gravity, so that the reinforcement part abuts against the bottom wall of the borehole. Then continue to lower the rail pile, so that the rail pile moves, and the reinforcement part rotates at the same time, and then pour concrete between the inner wall of the borehole and the rail pile. At this time, the connecting rod and the reinforcement part can play the role of steel bars in the reinforced concrete structure, thereby improving the reliability of the rail pile fixation and the strength of the protective structure.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-6 This application is described in further detail.

[0044] A rail pile retaining wall protection structure disclosed in the embodiment of the present application is referred to Figure 1 and Figure 2 The rail pile retaining wall protection structure includes multiple rows of rail piles 6 fixed to the slope 3, and the multiple rows of rail piles 6 are staggered. The rock and soil structure 4 of the slope 3 is provided with multiple rows of drill holes, and the rail piles 6 are placed inside the drill holes. The bottom of the rail pile 6 is rotatably connected to two connecting rods 12 (combined with Figure 4 ), the rotation axis of the connecting rod 12 is perpendicular to the length direction of the rail pile 6, and the end of the connecting rod 12 away from the rail pile 6 is fixedly connected to the reinforcing part 13, and the reinforcing part 13 is in the shape of a rectangular parallelepiped. Concrete is poured inside the borehole, and the concrete forms a support foot 11 at the end of the rail pile 6 inserted into the borehole. The support foot 11 is cylindrical, so that the connecting rod 12 and the reinforcing part 13 are located inside the support foot 11.

[0045] The support leg 11 can be fixed to the geotechnical structure 4, thereby improving the stability of the rail pile 6. When the rail pile 6 is lowered, the connecting rod 12 and the reinforcement part 13 naturally droop under the action of gravity, so that one end of the rail pile 6 can be lowered to the bottom of the borehole. When the rail pile 6 is lowered to the point where the reinforcement part 13 abuts against the bottom wall of the borehole, the rail pile 6 is further lowered, so that the reinforcement part 13 moves away from each other, and then when pouring concrete, the connecting rod 12 and the reinforcement part 13 can act as the steel bars of the reinforced concrete structure, thereby improving the strength of the support leg 11 and further improving the strength of the rail pile 6 fixed to the geotechnical structure 4.

[0046] Reference Figure 2 and Figure 3 The end of the rail pile 6 extending out of the geotechnical structure 4 is fixed with a steel mesh 5, and the two ends of each steel mesh 5 are respectively fixed to the adjacent rail pile 6. The retaining wall 2 is cast outside the end of the rail pile 6 extending out of the geotechnical structure 4, so that the steel mesh 5 is located inside the retaining wall 2. The steel mesh 5 can increase the contact area between the rail pile 6 and the retaining wall 2, thereby improving the structural stability of the retaining wall 2.

[0047] Reference Figure 3and Figure 5 The rail pile 6 extends out of the side wall of the geotechnical structure 4 and is fixedly connected to the first positioning part 9 by welding. The first positioning part 9 is slidably connected to an abutment plate 7, and a plurality of second positioning parts 10 are fixedly connected to the abutment plate 7. The wire mesh 5 is simultaneously penetrated through the first positioning part 9 and the plurality of second positioning parts 10. The first positioning part 9 is threadedly connected to a locking part 8, which is a nut.

[0048] The steel mesh 5 is passed through the first positioning part 9, and then the abutment plate 7 is sleeved on the first positioning part 9, so that the steel mesh 5 is passed through the plurality of second positioning parts 10, and then the locking part 8 is threadedly connected to the first positioning part 9, and the locking part 8 makes the abutment plate 7 and the rail pile 6 press against the steel mesh 5 together, so that the steel mesh 5 is fixed between the abutment plate 7 and the rail pile 6, and then the retaining wall 2 is cast. The first positioning part 9 and the plurality of second positioning parts 10 can position the steel mesh 5 from multiple points, thereby further improving the structural stability of the steel mesh 5 and reducing the shaking of the steel mesh 5 when casting the retaining wall 2.

[0049] Reference Figure 5 and Figure 6 The second positioning part 10 includes a housing 101, which is cylindrical. A slide groove 105 penetrating the housing 101 is provided along the axis of the housing 101. A clamping groove 106 is provided on the inner wall of the slide groove 105. A plurality of first elastic pieces 103 are fixedly connected to one end of the housing 101 close to the rail pile 6. The plurality of first elastic pieces 103 are arranged around the axis of the rail pile 6. The housing 101 is provided with a driving part 102, which includes a slider 1021. The slider 1021 is slidably connected to the inner wall of the slide groove 105. The slider 1021 is fixedly connected to the second elastic piece 104 at one end away from the rail pile 6. A clamping block 107 is fixedly connected to the side wall of the second elastic piece 104. The clamping block 107 corresponds to the clamping groove 106. A plurality of elastic members 1023 are arranged around the axis of the slider 1021 at one end close to the rail pile 6 , and a support portion 1022 is fixedly connected to the end of the elastic member 1023 away from the slider 1021 . The plurality of support portions 1022 correspond to the plurality of first elastic sheets 103 one by one.

[0050] When the slider 1021 does not move, the support portion 1022 is located inside the slide slot 105, and the elastic member 1023 undergoes elastic deformation ( Figure 6 The length of the middle elastic member 1023 can be designed according to actual conditions), so that the multiple support parts 1022 are pressed against the inner wall of the slide groove 105 at the same time, thereby fixing the position of the slider 1021 by friction.

[0051] After the steel mesh 5 is passed through the plurality of second positioning parts 10, the construction personnel move the slider 1021 so that one end of the slider 1021 passes through the slide slot 105, and the clamping block 107 is inserted into the clamping slot 106, thereby fixing the position of the slider 1021. At this time, the elastic member 1023 loses the constraint of the inner wall of the slide slot 105 and recovers its deformation, so that the plurality of support parts 1022 move in a direction away from each other, and the support part 1022 abuts against the first elastic sheet 103, and under the action of the elastic member 1023, the first elastic sheet 103 is deformed, so that the plurality of first elastic sheets 103 are deformed in a direction away from each other, so that the plurality of first elastic sheets 103 are pressed against the steel mesh 5, thereby improving the structural stability of the steel mesh 5, and reducing the shaking of the steel mesh 5 in the process of fixing the plurality of steel meshes 5 to the rail pile 6. When the slider 1021 moves along the slide slot 105 , the second elastic sheet 104 is deformed, so that the clamping block 107 can be inserted into the slide slot 105 and move inside the slide slot 105 .

[0052] Reference Figure 1 A plurality of drainage pipes 14 penetrating both sides of the retaining wall 2 are inserted into the retaining wall 2 , and a drainage channel 15 is provided in the rock structure 4 on the side of the retaining wall 2 away from the slope 3 , so that the water in the drainage pipes 14 can fall into the drainage channel 15 .

[0053] The drainage pipe 14 can lead the water on one side of the slope 3 into the drainage channel 15, and the drainage channel 15 will lead the water away, thereby reducing the accumulation of water at the retaining wall 2.

[0054] The implementation principle of the rail pile retaining wall protection structure of the embodiment of the present application is as follows: first, the construction personnel drill holes on the geotechnical structure 4 of the slope 3, then insert the rail pile 6 into the hole, and pour concrete in the hole. The concrete forms a support foot 11 at one end of the rail pile 6, and the support foot 11 is fixedly connected to the geotechnical structure 4. Then the construction personnel insert the wire mesh 5 into the first positioning part 9, and penetrate the abutment plate 7 on the first positioning part 9, so that the wire mesh 5 is simultaneously inserted into multiple second positioning parts 10, and then the locking part 8 is threadedly connected to the first positioning part 9, so that the abutment plate 7 fixes the wire mesh 5 to the rail pile 6. Then a template is set at the rail pile 6, and a drainage pipe 14 is penetrated on the template, and then concrete is poured in the template to form a retaining wall 2.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
