Description

Technical Field

[0001] This invention relates to the field of municipal pipeline foundation treatment technology, and in particular to an anti-collapse structure for the construction of municipal water supply pipelines. Background Technology

[0002] Currently, municipal engineering projects encounter various soil types during water pipeline construction, and the bearing capacity of different soil types varies. The traditional method is to use compaction to improve the bearing capacity of the foundation.

[0003] For example, Chinese patent CN119411624A discloses a fine sand foundation reinforcement structure and its construction method for laying municipal pipelines. The structure includes a fine sand base body and a soil base body at the bottom of the fine sand base body. Two earth-wood grids are laid on the top of the fine sand base body, and a clamping strip is installed between the two earth-wood grids. Support members are installed on the clamping strip to support the pipeline. Two fasteners connected by threads are symmetrically arranged on the clamping strip. By using the earth-wood grids and clamping strips, along with the fasteners and movable parts, both the first and second helical blades are deeply embedded in the soil base body, further improving the stability of the foundation, reinforcing it, and preventing foundation collapse. Both can be achieved by rotation, eliminating the need for complex excavation and filling work, saving construction time, and improving construction efficiency and quality.

[0004] The above-mentioned method uses fasteners and the first and second helical blades to stabilize the geogrid on the foundation and prevent foundation collapse. However, during the stabilization of the geogrid, the fasteners and movable parts are fixed with ropes. The downward movement of the fasteners will also cause the movable parts to move. There are three movable parts on one side. The movable part in the middle position will experience the least tension under the action of the rope. Furthermore, the downward movement of the fasteners is limited, which further reduces the tension on the movable part in the middle position. As a result, during the downward movement, the fasteners or movable parts on the side of the geogrid will move down deeper, while the middle position will move down shallower. This will cause the geogrid as a whole to tilt and become unstable, thus affecting the progress of water pipe installation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an anti-collapse structure for the construction of municipal water supply pipelines, so as to solve the problem that in the prior art, the tension of the movable part located in the middle position is minimized under the action of the rope, which reduces the tension of the movable part in the middle position when the fastener moves down. As a result, during the downward movement, the fasteners or movable parts on the side of the geogrid move down deeply, while the middle position moves down shallowly, and the geogrid as a whole becomes tilted and unstable.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A collapse-prevention structure for municipal water supply pipeline construction includes a geogrid, a clamping strip installed at the middle of the top of the geogrid, a fastening column installed at the bottom of the side of the geogrid, a movable column installed at the bottom of the side of the geogrid, an auxiliary column fixedly connected to the middle of the bottom of the geogrid, a bearing plate attached to the top of the clamping strip, and a support tray fixedly connected to the middle of the top of the geogrid; and a pressing assembly for assisting in fixing the geogrid to the soft soil foundation, the pressing assembly being connected to the geogrid and the clamping strip.

[0008] Optionally, the pressing assembly includes a deformation block fixedly connected to the top of the geogrid, a connecting column fixedly connected to the middle position of the bearing plate, an assisting disc installed on the top of the connecting column, a traction rope fixedly connected to the outer wall of the connecting column, a limit strap snapped onto the top of the bearing plate, and a snap-fit ​​hole provided on the outer wall of the bearing plate.

[0009] Optionally, a snap-fit ​​cylinder is fixedly connected to the top of the geogrid, an annular pressure plate is fixedly connected to the outer wall of the connecting column, an adapter groove is provided on the top of the bearing plate, and an adjustment block is fixedly connected to the top of the geogrid near the deformation block.

[0010] Optionally, a connecting column is fixedly connected through the inner wall of the adjusting block, and a plurality of adjusting grooves are provided on the outer wall of the adjusting block near the connecting column. A support plate is fixedly connected to the inner wall of the deformable block, and a weakening part is provided on the outer wall of the deformable block near the connecting column.

[0011] Optionally, the top of the movable vertebra is provided with a winding part, a folding canopy is fixedly connected to the outer wall of the middle position of the movable vertebra, an extension column is fixedly connected to the inner wall of the middle position of the movable vertebra, and an abutting column is fixedly connected to the middle position of the bottom of the extension column.

[0012] Optionally, a limiting block is fixedly connected to the inner wall of the movable vertebra near the abutting column, a blocking block is fixedly connected to the outer wall of the extension column, an opening hole is provided on the outer wall at the bottom of the movable vertebra, a limiting chamber is fixedly connected to the inner wall at the middle position of the movable vertebra, a bearing plate is fixedly connected to the bottom of the limiting chamber, and a retaining plate is fitted to the inner wall of the limiting chamber.

[0013] Optionally, a circular groove is formed on the inner wall of the bottom of the movable vertebra, and a sliding groove is formed on the inner wall of the movable vertebra near the open hole.

[0014] Optionally, the movable vertebral column is divided into an upper part and a lower part. The upper part is a cylinder, and the lower part is a cone. The cylinder is slidably connected to the middle position of the top of the cone and extends into the inner wall of the cone. The fastening vertebral column and the auxiliary vertebral column are both of integral structure. The bearing plate is shaped like a "Ji" character, and an arc-shaped groove is provided on the outer wall of the support tray.

[0015] Optionally, a clamping groove is provided at the top of the connecting column. The clamping groove is adapted to the bottom of the assisting disc. The inner wall of the clamping hole is slidably connected to the outer wall of the clamping cylinder. The size of the adapting groove is the same as the size of the towing rope. The towing ropes are symmetrically distributed about the center of the connecting column. One end of the limiting band is clamped to the top of the bearing plate. The deformation blocks and the adjusting blocks are both circumferentially arranged on the outer wall of the connecting column, and the number of the deformation blocks and the adjusting blocks is the same. A limiting disc is installed at the position of the fastening vertebral column at the bottom of the soil grid.

[0016] Optionally, the size of the winding part is adapted to the size of the towing rope. The folding shed is made of a flexible material. The size of the blocking block is adapted to the size of the open hole. The blocking block is made of an elastic material. The clamping disc is fixedly connected to the extending end of the cylinder of the movable vertebral column.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] [[ID=]]In the above solution, by setting the pressing component, not only can the depth of the downward movement of the fastening vertebral column be indirectly pressed and adjusted, improving the smoothness of the downward movement process of the fastening vertebral column, but also when the fastening vertebral column rotates and moves downward, it can pull the movable vertebral column on the side of the soil grid to rotate and move downward synchronously, ensuring the consistency of the downward movement of the fastening vertebral column and the movable vertebral column, thereby improving the overall stability of the soil grid and ensuring the progress of installing the water pipeline.

[0019] By setting deformation blocks, annular pressing discs, adjusting blocks, adjusting grooves and weakening parts in the pressing component, the annular pressing disc will move downward synchronously during the process of pressing the connecting column, and change the pressing force according to the difficulty of the rotation and downward movement of the fastening vertebral column, effectively improving the depth of the rotation and downward movement of the fastening vertebral column, the movable vertebral column and the auxiliary vertebral column and the progress of the operation. At the same time, by setting multiple layers of adjusting grooves and weakening parts, it is convenient to use the adjusting grooves and weakening parts to limit the annular pressing disc and the connecting column after the pressing is completed, so as to ensure that the soil grid is in a horizontal and stable state on the foundation surface, facilitating the installation of the water pipeline.

[0020] By incorporating a bearing plate and traction rope into the pressing assembly, the traction rope can be used to synchronously lower the movable vertices during the pressing process. Furthermore, to enhance the downward movement of the movable vertices, downward pressure is applied to the bearing plate. This pressure is transmitted to both the fixed and movable vertices, ensuring that the downward movement of the fixed and movable vertices is synchronized. This prevents uneven force distribution that could lead to different depths of downward movement between the fixed and movable vertices, which would otherwise prevent the geogrid from being firmly anchored to the fine sand base.

[0021] By setting up a blocking block, a retaining plate, and a bearing plate, the height of the retaining plate can be adjusted to remove the blocking block from the open hole, facilitating the entry of fine sand into the interior of the movable column cone, increasing the overall counterweight of the movable column, and improving the stability of the movable column in fixing the geogrid to the fine sand base. Moreover, it can be individually adjusted according to the needs of the actual scenario, improving the overall flexibility of the device. Attached Figure Description

[0044] like Figures 1 to 13As shown in the figure, an anti-collapse structure for municipal water supply pipeline construction provided by an embodiment of the present invention includes a geogrid 1. A pressing strip is installed at the middle position of the top of the geogrid 1. A fastening cone column 2 is installed at the bottom of the side of the geogrid 1. A movable cone column 3 is installed at the bottom of the side of the geogrid 1. An auxiliary cone column 4 is fixedly connected to the middle position of the bottom of the geogrid 1. A bearing plate 5 is fitted to the top of the pressing strip. A support tray 6 is fixedly connected to the middle position of the top of the geogrid 1; a pressing component, which is used to cooperate with the geogrid 1 to be fixed on the soft soil foundation, is connected to the geogrid 1 and the pressing strip. The movable cone column 3 is divided into two parts, the upper part is a cylinder, and the lower part is a cone. The cylinder is slidably connected to the middle position of the top of the cone and extends into the inner wall of the cone. Both the fastening cone column 2 and the auxiliary cone column 4 are of integral structure. The shape of the bearing plate 5 is "U". An arc groove is provided on the outer wall of the support tray 6. Anti-detachment structures are provided at the tops of the fastening cone column 2 and the movable cone column 3, which are adapted to the geogrid 1.

[0045] The specific working process is as follows: First, the surface of the fine sand base layer is pre-treated, including cleaning the surface debris, leveling the ground of the fine sand base layer, marking and planning the area of the geogrid 1 to be laid flat. After determining the area size of the geogrid 1, the geogrid 1 is laid flat and fixed on the surface of the fine sand base layer, and the geogrid 1 is continuously pushed deeper into the fine sand base layer to ensure that the geogrid 1 can be stably and firmly laid flat on the fine sand base layer. Finally, after the geogrid 1 is firmly fixed, the municipal water pipeline is placed at the top of the geogrid 1, and bolts or hoop parts are used to fix the water pipeline.

[0046] By setting the pressing component, not only can the depth of the downward movement of the fastening cone column 2 be adjusted by indirect pressing, improving the smoothness of the downward movement process of the fastening cone column, but also when the fastening cone column 2 rotates and moves downward, it can pull the movable cone column 3 on the side of the geogrid 1 to rotate and move downward synchronously, ensuring the consistency of the downward movement of the fastening cone column 2 and the movable cone column 3, thereby improving the overall stability of the geogrid 1 and ensuring the progress of installing the water pipeline.

[0047] As Figures 3 to 7As shown, the pressing assembly includes a deformable block 8 fixedly connected to the top of the geogrid 1, a connecting post 9 fixedly connected to the middle position of the bearing plate 5, an assisting disc 7 installed on the top of the connecting post 9, a traction rope 10 fixedly connected to the outer wall of the connecting post 9, a limit band 11 snapped onto the top of the bearing plate 5, a snap-fit ​​hole 12 opened on the outer wall of the bearing plate 5, a snap-fit ​​cylinder 13 fixedly connected to the top of the geogrid 1, an annular pressure plate 14 fixedly connected to the outer wall of the connecting post 9, an adaptation groove 15 opened on the top of the bearing plate 5, an adjusting block 16 fixedly connected to the top of the geogrid 1 near the deformable block 8, a connecting post 17 fixedly connected through the inner wall of the adjusting block 16, several adjusting grooves 18 opened on the outer wall of the adjusting block 16 near the connecting post 9, a support plate 19 fixedly connected to the inner wall of the deformable block 8, a weakening part 20 opened on the outer wall of the deformable block 8 near the connecting post 9, a snap-fit ​​groove opened on the top of the connecting post 9, the snap-fit ​​groove is adapted to the bottom of the assisting disc 7, and the snap-fit ​​hole 12 is fixedly connected to the top of the geogrid 1 near the top of the deformable block 8. The inner wall of 2 is slidably connected to the outer wall of the snap-fit ​​cylinder 13. The size of the adapter groove 15 is the same as the size of the traction rope 10. The traction rope 10 is symmetrically distributed about the center of the connecting column 9. One end of the limiting band 11 is snapped to the top of the bearing plate 5. The deformation block 8 and the adjusting block 16 are distributed in a circumferential array on the outer wall of the connecting column 9, and the number of deformation block 8 and the adjusting block 16 is the same. The fastening column 2 is installed with a limiting plate at the bottom of the earth grid 1. The snap-fit ​​cylinder 13 is made of plastic and is a cylinder with a hollow inner wall. It is distributed in a gradient. The top is an expansion type and the bottom is a normal cylindrical bottom. It is snapped to the inner wall of the snap-fit ​​hole 12 on both sides of the bearing plate 5. There are four deformation blocks 8 and four connecting columns 17. They are all made of rubber. The connecting column 17 passes through the middle of the inner wall of the adjusting block 16 and the deformation block 8. The thickness of the annular pressure plate 14 is the same as the size of the adjusting groove 18. The annular pressure plate 14 is made of rigid material and the diameter of the annular pressure plate 14 is larger than the diameter of the connecting column 9.

[0048] With the above structure, the geogrid 1 is laid flat on the fine sand foundation, and the assisting disc 7 is snapped into the snap-fit ​​groove at the top of the connecting column 9. Then, the assisting disc 7 is rotated clockwise. When the assisting disc 7 rotates, it will drive the connecting column 9 to rotate clockwise in sync. The traction rope 10 is symmetrically fixed to the center of the outer wall of the connecting column 9. After the connecting column 9 rotates clockwise, it will pull the traction rope 10 toward the position of the connecting column 9. During the rotation of the assisting disc 7, if there is a part of the fine sand of the foundation that is hard, it can be pressed down on the basis of the original rotation. By applying pressure to the assisting disc 7, the pressure is transmitted to the connecting column 9, and the annular pressure plate 14 fixed to the outer wall of the connecting column 9 also moves downward in sync.

[0049] During the downward movement, the annular pressure plate 14 contacts the tops of the deformable block 8 and the adjusting block 16. Since the deformable block 8 and the adjusting block 16 are made of rubber, they will both compress downwards when the annular pressure plate 14 presses down. As the pressing force increases, the annular pressure plate 14 will gradually move from the tops of the deformable block 8 and the adjusting block 16 towards the position of the adjusting groove 18 and the weakening part 20. The adjusting groove 18 has three adjustment positions. After entering each adjusting groove 18, the annular pressure plate 14 can be engaged. Through the friction of the adjusting groove 18, the fastening conical column 2, and the fine sand base, under the combined action of these three factors... The annular pressure plate 14 can be locked onto the inner wall of the adjusting groove 18 to ensure that the positions of the fixed vertebral column 2 and the movable vertebral column 3 are consistent. The downward movement depth of the auxiliary vertebral column 4 depends on the depth of the fixed vertebral column 2 and the movable vertebral column 3. When the fixed vertebral column 2 and the movable vertebral column 3 move downward, the auxiliary vertebral column 4 will also move downward synchronously. In order to ensure that the fixed vertebral column 2, the movable vertebral column 3 and the auxiliary vertebral column 4 are as close to the same level as possible, the pressure can be applied intermittently during the rotation of the assisting plate 7 to break up some of the harder fine sand through pressure, thereby ensuring that the fixed vertebral column 2, the movable vertebral column 3 and the auxiliary vertebral column 4 are at the same level during the downward movement.

[0050] During the tightening process of the traction rope 10 toward the connecting post 9, the limiting band 11 can be used to limit the traction rope 10 to prevent it from disengaging from the adapter groove 15, thus causing the traction rope 10 to be unloaded or deviated during the tightening process. When the connecting post 9 rotates, more and more traction rope 10 will be wound on the outer wall of the connecting post 9, indirectly increasing the diameter of the outer wall of the connecting post 9. Since the diameter of the annular pressure plate 14 is larger than the diameter of the connecting post 9, and the annular pressure plate 14 is located below the traction rope 10, when the connecting post 9 moves downward, the deformation block 8 and the adjusting block 16 will contact the annular pressure plate 14 first, and then contact the traction rope 10. The actual downward displacement depth of the fixed vertebral column 2, movable vertebral column 3, and auxiliary vertebral column 4 is limited. The winding size of the traction rope 10 on the outer wall of the connecting column 9 will not be larger than the size of the annular pressure plate 14. Therefore, the traction rope 10 will not be affected during the winding process, nor will it affect the limiting between the annular pressure plate 14 and the adjustment groove 18. In fact, when the annular pressure plate 14 is located at the bottom of the adjustment groove 18, the friction generated by the contact between the traction rope 10 and the upper two sides of the adjustment groove 18 after winding will help the annular pressure plate 14 to limit the connecting column 9 and prevent the connecting column 9 from moving upward and resetting under the elastic force of the deformation block 8 and the adjustment block 16.

[0051] As the connecting column 9 moves downward, the bearing plate 5 fixed to the outer wall of the connecting column 9 also moves downward synchronously. During the movement of the bearing plate 5, the traction rope 10 always slides in contact with the snap-fit ​​cylinder 13. Since the connecting column 9 is intermittently pressed in the initial state (the annular pressure plate 14 has not entered the adjustment groove 18), it can effectively improve the downward movement progress of the fastening vertebra 2, the movable vertebra 3 and the auxiliary vertebra 4. Therefore, in order to prevent the bearing plate 5 from being subjected to the rebound force of the deformation block 8 and the adjustment block 16 after being pressed, the top position of the snap-fit ​​cylinder 13 is set to an expansion type. At this time, when the bearing plate 5 moves upward to the expansion end of the snap-fit ​​cylinder 13, the friction between the inner wall of the snap-fit ​​hole 12 and the outer wall of the expansion end of the snap-fit ​​cylinder 13 increases, thereby reducing the speed and playing a buffering role, so as to avoid the bearing plate 5 from having too large an amplitude, which would affect the stability of the entire geogrid 1.

[0052] Furthermore, the assist plate 7 is a detachable structure. When the connecting column 9 rotates, it is engaged in the locking groove at the top of the connecting column 9. After the tightened vertices 2, movable vertices 3 and auxiliary vertices 4 are completely fixed in the foundation, the assist plate 7 can be removed. In addition, when the assist plate 7 is not installed, the height of the connecting column 9 is lower than the height of the support tray 6. Furthermore, grooves are opened at the middle positions of both sides in the long direction and the short direction of the earth grid 1 for widening and lengthening the earth grid 1 during construction.

[0053] It is worth mentioning that when the annular pressure plate 14 contacts the adjusting groove 18 and the weakened part 20, the position of the weakened part 20 will cause the middle position of the adjusting block 16 to be concave inward, and the upper and lower ends will wrap around the middle position. The support plate 19 can prevent the weakened part 20 from deforming and fatigued after being subjected to pressure multiple times. After fatigue, the weakened part 20 cannot be reset in time and loses its ability to support the annular pressure plate 14 and the connecting column 9 in an unstable state, thus affecting the overall stability of the geogrid 1.

[0054] By incorporating a deformation block 8, annular pressure plate 14, adjusting block 16, adjusting groove 18, and weakening part 20 into the pressing assembly, the annular pressure plate 14 moves downward synchronously during the pressing of the connecting column 9. The pressing force is adjusted according to the ease with which the fastening vertebra 2 rotates downward, effectively increasing the downward depth of the fastening vertebra 2, the movable vertebra 3, and the auxiliary vertebra 4, and improving the progress of the operation. Furthermore, the multi-layered adjusting groove 18 and weakening part 20 allow for the limitation of the annular pressure plate 14 and the connecting column 9 after pressing, ensuring that the geogrid 1 remains horizontally stable on the foundation surface, facilitating the installation of water pipes.

[0055] By setting a bearing plate 5 and a traction rope 10 in the pressing assembly, not only can the traction rope 10 drive the movable vertebral column 3 to move down synchronously during the pressing of the connecting column 9, but also, in order to improve the downward movement of the movable vertebral column 3, pressure is applied downward to the bearing plate 5. The pressure force is transmitted to the fastening vertebral column 2 and the movable vertebral column 3 respectively, so that the fastening vertebral column 2 can also take into account the downward movement of the movable vertebral column 3 during the downward movement. This ensures the downward movement of the fastening vertebral column 2 and the movable vertebral column 3, and avoids the difference in the downward movement depth of the fastening vertebral column 2 and the movable vertebral column 3 due to uneven force, which would cause the geogrid 1 to be unable to be firmly fixed on the fine sand base.

[0056] like Figures 8 to 13 As shown, the top of the movable vertebral column 3 is provided with a winding part 21. A folding canopy 22 is fixedly connected to the outer wall of the middle position of the movable vertebral column 3. An extension column 23 is fixedly connected to the inner wall of the middle position of the movable vertebral column 3. An abutting column 24 is fixedly connected to the middle position of the bottom of the extension column 23. A limiting block 25 is fixedly connected to the inner wall of the movable vertebral column 3 near the abutting column 24. A blocking block 26 is fixedly connected to the outer wall of the extension column 23. An opening hole 27 is provided on the outer wall of the bottom end of the movable vertebral column 3. A limiting chamber 29 is fixedly connected to the inner wall of the middle position of the movable vertebral column 3. A bearing plate 30 is fixedly connected to the bottom of the limiting chamber 29. A retaining plate 28 is attached to the inner wall of the limiting chamber 29. A circular groove 31 is provided on the inner wall of the bottom of the movable vertebral column 3. A sliding groove 32 is provided on the inner wall of the movable vertebral column 3 near the opening hole 27. The folding canopy 22 is made of flexible material. The blocking block... The size of 26 is adapted to the size of the open hole 27. The blocking block 26 is made of elastic material. The retaining plate 28 is fixedly connected to the cylindrical extension end of the movable vertebra 3. The bearing plate 30 is divided into upper and lower layers, with the upper layer being unclosed and the lower layer being fully closed. The size of the unclosed notch in the upper layer is consistent with the size of the retaining plate 28. The inner wall size of the limiting chamber 29 is consistent with the size of the retaining plate 28. The blocking block 26 is made of rubber. There are four limiting blocks 25, which are distributed in a circumferential array on the inner wall of the lower part of the cone of the movable vertebra 3. The layout of the limiting chamber 29 is consistent with that of the bearing plate 30. It is divided into two layers, with two blocks in each layer. One end is closed and the other end is open. The open end allows the retaining plate 28 to slide in, and the closed end is used to ensure that the retaining plate 28 slides in completely. The contact post 24 and the limiting block 25 are made of metal.

[0057] Through the above structure, after pressing and rotating the connecting column 9 in the previous step, the traction rope 10 will be tightened, causing the traction rope 10 on the top winding part 21 of the movable column 3 to gradually change from a coiled state to an unfolded state, and causing the movable column 3 to rotate. At the same time, the downward movement of the bearing plate 5 will also cause the movable column 3 to move downward. Thus, the downward movement of the movable column 3 is consistent with the downward movement of the fastening column 2. Either it rotates and moves downward alone, using the self-weight of the earth grid 1 to gradually push the fastening column 2, the movable column 3 and the auxiliary column 4 into the fine sand foundation, or it is pressed during the rotation to accelerate the downward movement speed of the fastening column 2, the movable column 3 and the auxiliary column 4.

[0058] The pressing can be selected as intermittent or continuous. If, after rotating for a period of time, the geogrid 1 shows no signs of downward movement, the pressure can be transferred to the connecting column 9 and the bearing plate 5 by pressing the assisting disc 7, thereby applying pressure to the fastening vertices 2, the movable vertices 3, and the auxiliary vertices 4. The auxiliary vertices 4 remain stationary, relying solely on pressure. After the movable vertices 3 enter the fine sand foundation, to improve the overall stability of the geogrid 1, the upper cylindrical surface of the movable vertices 3 can be manually rotated during the pressing process, thereby rotating the retaining disc 28 out of the inner wall of the limiting chamber 29 (e.g., Figure 10 As shown in the diagram, this is the initial state. Afterwards, gently lift the plate 28 upwards, moving it from the lower layer's support plate 30 to the upper layer's support plate 30 and rotating it in any direction until the plate 28 slides into the inner wall of the limiting chamber 29 and cannot move further. This indicates that the plate 28 has moved from the lower layer to the upper layer. Alternatively, during the upward movement of the plate 28, its extension post 23 and contact post 24 move upwards synchronously. When the contact post 24 reaches its maximum upward position, it will contact the limiting block 25. If a metallic clanging sound is heard during the upward movement of the plate 28, it indicates that the contact post 24 is in contact with the limiting block 25. At this point, it means that the plate 28 has moved from the lower layer's support plate 30 to the upper layer's support plate 30. Then, rotate the upper part of the cylinder of the movable conical column 3.

[0059] When the movable vertices 3 are not in operation and are not deeply embedded in the fine sand foundation, the retaining plate 28 is always positioned at the gap between the lower bearing plate 30 and the upper bearing plate 30, and the upper and lower parts of the movable vertices 3 are limited by the folding canopy 22. Although the folding canopy 22 is made of rubber, it allows for some misalignment between the upper and lower parts of the movable vertices 3. On the one hand, when penetrating the fine sand foundation, it can closely adhere to the fine sand soil, widen the channel, and collect the fine sand soil into the cone of the lower part of the movable vertices 3, improving the stability after penetration and the convenience of removal. On the other hand, if the geogrid 1 tilts or shifts, the state of the geogrid 1 on the surface of the fine sand foundation can be adjusted by slightly changing the height and tilt angle of the movable vertices 3. As the retaining plate 28 moves upward, the extension column 23 and the contact column 24 also move synchronously, and the blocking block 26 on the extension column 23 also disengages from the opening hole 27. At this time, the cone of the lower part of the movable vertices 3... The fine sand has penetrated deep into the fine sand foundation. It enters the cone of the movable vertices 3 through the open hole 27, and with a slight adjustment to the movable vertices 3, the fine sand adheres more tightly to the outer surface of the cone of the movable vertices 3. A large amount of fine sand also enters the cone of the movable vertices 3, increasing the overall weight of the movable vertices 3. Each movable vertices 3 can be adjusted individually, improving the flexibility of the device. During the upward movement of the extension column 23, due to the weight of the main structure of the geogrid 1, in order to reduce the difficulty of moving the clamping plate 28 upward, a circular groove 31 and a sliding groove 32 are set on the upward movement path of the blocking block 26 and the contact column 24 to reduce the friction of the blocking block 26 on the inner wall of the cone of the movable vertices 3 and the friction of the contact column 24 on the inner wall of the cone of the movable vertices 3. After the movable vertices 3 are adjusted, the geogrid 1 is gently pushed to check the stability. If there is no displacement or loosening, the water pipes are then laid at the support tray 6.

[0060] By setting up the blocking block 26, the retaining plate 28, the limiting chamber 29, and the bearing plate 30, not only can the height of the retaining plate 28 be adjusted to remove the blocking block 26 from the opening hole 27, making it easier for fine sand to enter the interior of the movable vertices 3, increasing the overall counterweight of the movable vertices 3, and improving the stability of the movable vertices 3 in fixing the geogrid 1 to the fine sand base, but also can be individually adjusted according to the needs of the actual scene, improving the overall flexibility of the device.

[0061] The workflow of the technical solution provided by this invention is as follows:

[0062] First, the surface of the fine sand base layer is pre-treated, including cleaning up surface debris, leveling the ground of the fine sand base layer, marking and planning the area of ​​the earth grid 1, and after determining the area size of the earth grid 1, the earth grid 1 is laid flat and fixed on the surface of the fine sand base layer, and the earth grid 1 is continuously pushed into the interior of the fine sand base layer to ensure that the earth grid 1 can be laid stably and firmly on the fine sand base layer. Finally, after the earth grid 1 is firmly fixed, the municipal water pipe is placed on top of the earth grid 1 and fixed with bolts or clamps.

[0063] First, lay the earth and wood grid 1 flat on the fine sand foundation. Then, snap the auxiliary disk 7 into the snap-fit ​​groove at the top of the connecting column 9. Then, start rotating the auxiliary disk 7 clockwise. When the auxiliary disk 7 rotates, it will drive the connecting column 9 to rotate clockwise in sync. The traction rope 10 is symmetrically fixed to the center of the outer wall of the connecting column 9. After the connecting column 9 rotates clockwise, it will pull the traction rope 10 toward the position of the connecting column 9. During the rotation of the auxiliary disk 7, if there is a part of the fine sand in the foundation that is hard, it can be pressed down on the basis of the original rotation. By applying pressure to the auxiliary disk 7, the pressure is transmitted to the connecting column 9, and the annular pressure plate 14 fixed to the outer wall of the connecting column 9 also moves downward in sync.

[0064] During the downward movement, the annular pressure plate 14 contacts the tops of the deformable block 8 and the adjusting block 16. Since the deformable block 8 and the adjusting block 16 are made of rubber, they will both compress downwards when the annular pressure plate 14 presses down. As the pressing force increases, the annular pressure plate 14 will gradually move from the tops of the deformable block 8 and the adjusting block 16 towards the position of the adjusting groove 18 and the weakening part 20. The adjusting groove 18 has three adjustment positions. After entering each adjusting groove 18, the annular pressure plate 14 can be engaged. Through the friction of the adjusting groove 18, the fastening conical column 2, and the fine sand base, under the combined action of these three factors... The annular pressure plate 14 can be locked onto the inner wall of the adjusting groove 18 to ensure that the positions of the fixed vertebral column 2 and the movable vertebral column 3 are consistent. The downward movement depth of the auxiliary vertebral column 4 depends on the depth of the fixed vertebral column 2 and the movable vertebral column 3. When the fixed vertebral column 2 and the movable vertebral column 3 move downward, the auxiliary vertebral column 4 will also move downward synchronously. In order to ensure that the fixed vertebral column 2, the movable vertebral column 3 and the auxiliary vertebral column 4 are as close to the same level as possible, the pressure can be applied intermittently during the rotation of the assisting plate 7 to break up some of the harder fine sand through pressure, thereby ensuring that the fixed vertebral column 2, the movable vertebral column 3 and the auxiliary vertebral column 4 are at the same level during the downward movement.

[0065] During the tightening process of the traction rope 10 toward the connecting post 9, the limiting band 11 can be used to limit the traction rope 10 to prevent it from disengaging from the adapter groove 15, thus causing the traction rope 10 to be unloaded or deviated during the tightening process. When the connecting post 9 rotates, more and more traction rope 10 will be wound on the outer wall of the connecting post 9, indirectly increasing the diameter of the outer wall of the connecting post 9. Since the diameter of the annular pressure plate 14 is larger than the diameter of the connecting post 9, and the annular pressure plate 14 is located below the traction rope 10, when the connecting post 9 moves downward, the deformation block 8 and the adjusting block 16 will contact the annular pressure plate 14 first, and then contact the traction rope 10. The actual downward displacement depth of the fixed vertebral column 2, movable vertebral column 3, and auxiliary vertebral column 4 is limited. The winding size of the traction rope 10 on the outer wall of the connecting column 9 will not be larger than the size of the annular pressure plate 14. Therefore, the traction rope 10 will not be affected during the winding process, nor will it affect the limiting between the annular pressure plate 14 and the adjustment groove 18. In fact, when the annular pressure plate 14 is located at the bottom of the adjustment groove 18, the friction generated by the contact between the traction rope 10 and the upper two sides of the adjustment groove 18 after winding will help the annular pressure plate 14 to limit the connecting column 9 and prevent the connecting column 9 from moving upward and resetting under the elastic force of the deformation block 8 and the adjustment block 16.

[0066] As the connecting column 9 moves downward, the bearing plate 5 fixed to the outer wall of the connecting column 9 also moves downward synchronously. During the movement of the bearing plate 5, the traction rope 10 always slides in contact with the snap-fit ​​cylinder 13. Since the connecting column 9 is intermittently pressed in the initial state (the annular pressure plate 14 has not entered the adjustment groove 18), it can effectively improve the downward movement progress of the fastening vertebra 2, the movable vertebra 3 and the auxiliary vertebra 4. Therefore, in order to prevent the bearing plate 5 from being subjected to the rebound force of the deformation block 8 and the adjustment block 16 after being pressed, the top position of the snap-fit ​​cylinder 13 is set to an expansion type. At this time, when the bearing plate 5 moves upward to the expansion end of the snap-fit ​​cylinder 13, the friction between the inner wall of the snap-fit ​​hole 12 and the outer wall of the expansion end of the snap-fit ​​cylinder 13 increases, thereby reducing the speed and playing a buffering role, so as to avoid the bearing plate 5 from having too large an amplitude, which would affect the stability of the entire geogrid 1.

[0067] Furthermore, the assist plate 7 is a detachable structure. When the connecting column 9 rotates, it is engaged in the locking groove at the top of the connecting column 9. After the tightened vertices 2, movable vertices 3 and auxiliary vertices 4 are completely fixed in the foundation, the assist plate 7 can be removed. In addition, when the assist plate 7 is not installed, the height of the connecting column 9 is lower than the height of the support tray 6. Furthermore, grooves are opened at the middle positions of both sides in the long direction and the short direction of the earth grid 1 for widening and lengthening the earth grid 1 during construction.

[0068] It is worth mentioning that when the annular pressure plate 14 contacts the adjusting groove 18 and the weakened part 20, the position of the weakened part 20 will cause the middle position of the adjusting block 16 to be concave inward, and the upper and lower ends will wrap around the middle position. The support plate 19 can prevent the weakened part 20 from deforming and fatigued after being subjected to pressure multiple times. After fatigue, the weakened part 20 cannot be reset in time and loses its ability to support the annular pressure plate 14 and the connecting column 9 in an unstable state, thus affecting the overall stability of the geogrid 1.

[0069] After pressing and rotating the connecting column 9 in the previous step, the traction rope 10 will be tightened, causing the traction rope 10 on the top winding part 21 of the movable column 3 to gradually change from a coiled state to an unwound state, and causing the movable column 3 to rotate. At the same time, the downward movement of the bearing plate 5 will also cause the movable column 3 to move downward. Thus, the downward movement of the movable column 3 is consistent with the downward movement of the fastening column 2. Either it rotates and moves downward alone, using the self-weight of the earth grid 1 to gradually push the fastening column 2, the movable column 3 and the auxiliary column 4 into the fine sand foundation, or it is pressed during the rotation to accelerate the downward movement speed of the fastening column 2, the movable column 3 and the auxiliary column 4.

[0070] The pressing can be selected as intermittent or continuous. If, after rotating for a period of time, the geogrid 1 shows no signs of downward movement, the pressure can be transferred to the connecting column 9 and the bearing plate 5 by pressing the assisting disc 7, thereby applying pressure to the fastening vertices 2, the movable vertices 3, and the auxiliary vertices 4. The auxiliary vertices 4 remain stationary, relying solely on pressure. After the movable vertices 3 enter the fine sand foundation, to improve the overall stability of the geogrid 1, the upper cylindrical surface of the movable vertices 3 can be manually rotated during the pressing process, thereby rotating the retaining disc 28 out of the inner wall of the limiting chamber 29 (e.g., Figure 10 As shown in the diagram, this is the initial state. Afterwards, gently lift the plate 28 upwards, moving it from the lower layer's support plate 30 to the upper layer's support plate 30 and rotating it in any direction until the plate 28 slides into the inner wall of the limiting chamber 29 and cannot move further. This indicates that the plate 28 has moved from the lower layer to the upper layer. Alternatively, during the upward movement of the plate 28, its extension post 23 and contact post 24 move upwards synchronously. When the contact post 24 reaches its maximum upward position, it will contact the limiting block 25. If a metallic clanging sound is heard during the upward movement of the plate 28, it indicates that the contact post 24 is in contact with the limiting block 25. At this point, it means that the plate 28 has moved from the lower layer's support plate 30 to the upper layer's support plate 30. Then, rotate the upper part of the cylinder of the movable conical column 3.

[0071] When the movable vertices 3 are not in operation and are not deeply embedded in the fine sand foundation, the retaining plate 28 is always positioned at the gap between the lower bearing plate 30 and the upper bearing plate 30, and the upper and lower parts of the movable vertices 3 are limited by the folding canopy 22. Although the folding canopy 22 is made of rubber, it allows for some misalignment between the upper and lower parts of the movable vertices 3. On the one hand, when penetrating the fine sand foundation, it can closely adhere to the fine sand soil, widen the channel, and collect the fine sand soil into the cone of the lower part of the movable vertices 3, improving the stability after penetration and the convenience of removal. On the other hand, if the geogrid 1 tilts or shifts, the state of the geogrid 1 on the surface of the fine sand foundation can be adjusted by slightly changing the height and tilt angle of the movable vertices 3. As the retaining plate 28 moves upward, the extension column 23 and the contact column 24 also move synchronously, and the blocking block 26 on the extension column 23 also disengages from the opening hole 27. At this time, the cone of the lower part of the movable vertices 3... The fine sand has penetrated deep into the fine sand foundation. It enters the cone of the movable vertices 3 through the open hole 27, and with a slight adjustment to the movable vertices 3, the fine sand adheres more tightly to the outer surface of the cone of the movable vertices 3. A large amount of fine sand also enters the cone of the movable vertices 3, increasing the overall weight of the movable vertices 3. Each movable vertices 3 can be adjusted individually, improving the flexibility of the device. During the upward movement of the extension column 23, due to the weight of the main structure of the geogrid 1, in order to reduce the difficulty of moving the clamping plate 28 upward, a circular groove 31 and a sliding groove 32 are set on the upward movement path of the blocking block 26 and the contact column 24 to reduce the friction of the blocking block 26 on the inner wall of the cone of the movable vertices 3 and the friction of the contact column 24 on the inner wall of the cone of the movable vertices 3. After the movable vertices 3 are adjusted, the geogrid 1 is gently pushed to check the stability. If there is no displacement or loosening, the water pipes are then laid at the support tray 6.
