Description

Technical Field

[0001] The present invention relates to the technical field of anti-settlement structures, and in particular to an anti-settlement structure for the ground surrounding a building and a construction process. Background Art

[0002] Ground subsidence can cause uneven stress in a building's foundation and walls. This uneven stress distribution can damage the structure of a building, manifesting itself as cracks in the walls and, in severe cases, even collapse. Furthermore, foundation subsidence can cause deformation or damage to load-bearing structures like beams and columns, further impacting the overall stability of the building.

[0003] To prevent ground subsidence around buildings, existing common technology typically involves driving multiple piles into the ground around the building, backfilling the space between the piles with soil, gravel, and the like, and then compacting the backfilled soil and gravel. While this process can enhance the structural strength of the ground around the building to a certain extent, the piles driven into the ground are typically prefabricated concrete piles, and without a suitable reinforcement structure between the concrete piles and the soil. Repeated exposure to heavy vehicles on the ground around the building can cause the piles to sink, especially in areas with frequent vehicle traffic. This can lead to soil subsidence in these areas. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a ground anti-settlement structure and construction process for the periphery of a building.

[0005] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a ground anti-subsidence structure and construction process for the periphery of a building, comprising a plurality of pile basic bodies driven into the foundation around the building, a compacted gravel layer and a soil layer backfilled between the plurality of pile basic bodies, a vertical mounting hole provided at the upper end of the pile basic body, a threaded rod rotatably mounted on the inner bottom wall of the vertical mounting hole, a plurality of transverse mounting holes arranged laterally and connected to the vertical mounting hole provided on the side wall of the pile basic body, the plurality of transverse mounting holes being located on one side of the threaded rod, a reinforcement rod being slidably mounted in each of the transverse mounting holes, a driving mechanism for driving the threaded rod to rotate being provided on the pile basic body, a resistance assembly located in the vertical mounting hole being provided on the threaded rod, and the resistance assembly driving the reinforcement rods one by one from the opening of the transverse mounting hole into the soil layer during the rotation of the threaded rod.

[0006] By adopting the above technical solution, multiple pile basic bodies distributed in a rectangular array are driven into the soil around the ground outside the building in sequence, and after ensuring that the tops of the multiple pile basic bodies are at the same height from the ground, the staff can drive the threaded rod to rotate through the driving mechanism, so that the interference assembly drives the reinforcement rods one by one from the openings of the transverse mounting holes into the soil layer during the rotation of the threaded rod, thereby realizing the reinforcement operation of the pile basic bodies, enhancing the connection strength between the multiple pile basic bodies and the soil, and after backfilling and compacting the gravel layer and soil layer, ensuring the structural strength of the ground outside the building, reducing the probability of settlement of the soil around the pile basic bodies due to frequent vehicle rolling.

[0007] Furthermore, the end of the reinforcement rod close to the opening of the horizontal mounting hole is pyramidal, and a transmission bevel is provided at the intersection between the end of the reinforcement rod away from the opening of the horizontal mounting hole and the top of the reinforcement rod, and the transmission bevel extends to a position close to the pyramidal end of the reinforcement rod. The interference assembly includes a movable plate that is sleeved on the threaded rod and threadedly connected, and an interference block fixed to the bottom of the movable plate at a position corresponding to the transmission bevel, the bottom surface of the interference block is an inclined surface that cooperates with the inclined surface of the transmission bevel, and the two ends of the movable plate respectively abut against the inner walls on both sides of the vertical mounting hole.

[0008] By adopting the above technical solution, since the movable plate is threadedly connected to the threaded rod, the two ends of the movable plate are respectively in contact with the inner walls on both sides of the vertical mounting hole. When the driving mechanism drives the threaded rod to rotate, the movable plate is able to descend, and the inclined surface at the bottom of the abutment block gradually slides along the bottom wall of the transmission inclined groove, and the reinforcement rod is gradually inserted into the soil from the opening of the horizontal mounting hole for reinforcement, which is beneficial to improve the reinforcement effect of the ground outside the building and ensure the anti-subsidence effect.

[0009] Furthermore, a limit assembly is provided in the vertical mounting hole to prevent the reinforcing rod inserted into the soil layer from retreating. The number of groups of the limit assemblies is equal to the number of reinforcement rods and the positions correspond one to one. Each group of the limit assemblies includes a fixed plate fixed on the inner wall of the vertical mounting hole, a movable rod that is provided through the fixed plate and slides together, a positioning rod fixed to the lower end of the movable rod, a connecting plate fixed to the upper end of the movable rod, and a spring that is sleeved on the movable rod and fixed between the bottom of the connecting plate and the top of the fixed plate. The lower end of the positioning rod is pressed against the top of the reinforcement rod under the action of the spring. A positioning groove is provided through the reinforcement rod for the positioning rod to be plugged in and matched and is connected to the bottom wall of the transmission inclined groove, and the side of the positioning groove away from the pyramidal end of the reinforcement rod is connected to the side wall of the reinforcement rod away from its pyramidal end.

[0010] By adopting the above technical solution, when the inclined surface at the bottom of the resistance block is completely separated from the transmission inclined groove, the positioning rod moves downward under the tension of the spring and engages with the positioning groove. The positioning rod plays a good limiting role on the reinforcement rod, ensuring the stability of the reinforcement rod after being inserted into the soil and reducing the probability of the reinforcement rod retreating.

[0011] Furthermore, the threaded rod passes through the inner top wall of the vertical mounting hole and is rotatably connected. A mounting plate is provided above the pile basic body. A plurality of support blocks evenly distributed about the central axis of the pile basic body are fixed to the bottom of the mounting plate. The driving mechanism includes a transmission assembly and a driving assembly. The transmission assembly includes a round block body fixed to the upper end of the threaded rod, a transmission shaft passing through the mounting plate and rotatably connected, a transmission block fixed to the lower end of the transmission shaft, and a driven gear fixedly sleeved on the transmission shaft. A transmission groove for the transmission block to be plugged in and matched is provided on the top of the round block body, and the driving assembly is used to drive the driven gear to rotate.

[0012] Furthermore, the driving assembly includes a driving gear rotatably mounted at the center of the mounting plate and meshing with the driven gear, and a motor fixed to the mounting plate and used to drive the driving gear to rotate.

[0013] By adopting the above technical solution, the motor drives the driving gear to rotate after working, so that the driven gear meshing with the driving gear, the transmission shaft fixed to the driven gear, and the transmission block fixed to the lower end of the transmission shaft all rotate, thereby causing the round block body plugged into the transmission block and the threaded rod fixed to the round block body to rotate, and finally causing the movable plate and the resistance block to descend and completing the operation of extruding the reinforcement rod for reinforcement.

[0014] Furthermore, the vertical mounting holes and the threaded rods are each provided with four and are evenly distributed about the central axis of the pile basic body. The transverse mounting holes are provided in four rows in the vertical direction. The four rows of transverse mounting holes are respectively located on the circumferential sides of the central axis of the pile basic body. The two rows of transverse mounting holes on the opposite sides of the pile basic body are equal in height. The openings of the two rows of transverse mounting holes on the opposite sides of the pile basic body are respectively located on both sides of the pile basic body. The two rows of transverse mounting holes on the adjacent sides of the pile basic body are alternately arranged up and down. The number of the reinforcement rods is equal to the number of the transverse mounting holes and the positions correspond one to one. The interference components are provided in four groups and correspond to the positions of the four rows of transverse mounting holes respectively. There are four driven gears and they are respectively located on the four threaded rods.

[0015] By adopting the above technical solution, the pile basic body can obtain the reinforcement effect of the reinforcement rod in four directions.

[0016] Furthermore, the pile base body consists of a first pile foundation and a second pile foundation that are detachably connected and structurally symmetrical.

[0017] By adopting the above technical solution, it is easy to install the threaded rod, positioning assembly, interference assembly, etc.

[0018] This application also discloses a ground anti-settlement structure for the periphery of a building and a construction process, comprising the following steps:

When the cam is in the state of rotation and the gears are turned, the cam is rotated, and the gears are turned, the cam is rotated, and the gears are turned. When the cam is in the state of rotation and the gears are turned, the cam is rotated, and the gears are turned.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] like Figure 1-8As shown, the embodiment of the present application discloses an anti-subsidence structure and construction process for the ground around a building, including multiple pile basic bodies 1 driven into the foundation around the building, and compacted gravel layers and soil layers backfilled between the multiple pile basic bodies 1 (the gravel layer and the soil layer are not shown in the figure). A vertical mounting hole 13 is provided at the upper end of the pile basic body 1, and a threaded rod 2 is rotatably mounted on the inner bottom wall of the vertical mounting hole 13. The side wall of the pile basic body 1 is provided with multiple transverse mounting holes 14 that are laterally arranged and connected to the vertical mounting holes 13. The multiple transverse mounting holes 14 are all located on one side of the threaded rod 2, and a reinforcement rod 3 is slidably mounted in each transverse mounting hole 14. A driving mechanism 4 for driving the threaded rod 2 to rotate is provided on the pile basic body 1, and a resistance component 5 located in the vertical mounting hole 13 is provided on the threaded rod 2. During the rotation of the threaded rod 2, the resistance component 5 drives the reinforcement rods 3 one by one from the opening of the transverse mounting hole 14 into the soil layer.

[0037] After driving a plurality of pile basic bodies 1 distributed in a rectangular array into the soil around the ground outside the building in turn and ensuring that the tops of the plurality of pile basic bodies 1 are at the same height from the ground, the staff can drive the threaded rod 2 to rotate through the driving mechanism 4, so that the interference component 5 drives the reinforcement rod 3 one by one from the opening of the transverse mounting hole 14 into the soil layer during the rotation of the threaded rod 2, thereby realizing the reinforcement operation of the pile basic body 1, enhancing the connection strength between the plurality of pile basic bodies 1 and the soil, and after backfilling and compacting the gravel layer and soil layer, ensuring the structural strength of the ground outside the building, reducing the probability of settlement due to frequent vehicle rolling over of the soil around the pile basic body 1.

[0038] The end of the reinforcement rod 3 close to the opening of the horizontal mounting hole 14 is pyramidal, and a transmission bevel 31 is provided at the intersection between the end of the reinforcement rod 3 away from the opening of the horizontal mounting hole 14 and the top of the reinforcement rod 3. The transmission bevel 31 extends to a position close to the pyramid end of the reinforcement rod 3. The interference assembly 5 includes a movable plate 51 that is sleeved on the threaded rod 2 and threadedly connected, and an interference block 52 fixed to the bottom of the movable plate 51 at a position corresponding to the transmission bevel 31. The bottom surface of the interference block 52 is an inclined surface that cooperates with the inclined surface of the transmission bevel 31. The two ends of the movable plate 51 respectively abut the inner walls on both sides of the vertical mounting hole 13.

[0039] Since the movable plate 51 is threadedly connected to the threaded rod 2, the two ends of the movable plate 51 are respectively in contact with the inner walls on both sides of the vertical mounting hole 13. When the driving mechanism 4 drives the threaded rod 2 to rotate, the movable plate 51 is able to descend, and the inclined surface at the bottom of the abutment block 52 gradually slides along the inner bottom wall of the transmission inclined groove 31, and the reinforcement rod 3 is gradually inserted into the soil from the opening of the horizontal mounting hole 14 for reinforcement, which is beneficial to improve the reinforcement effect of the ground outside the building and ensure the anti-subsidence effect.

[0040] A limit assembly 6 is provided in the vertical mounting hole 13 to prevent the reinforcement rod 3 inserted into the soil layer from retreating. The number of limit assemblies 6 is equal to the number of reinforcement rods 3 and the positions correspond one to one. Each group of limit assemblies 6 includes a fixed plate 61 fixed on the inner wall of the vertical mounting hole 13, a movable rod 62 that is arranged on the fixed plate 61 and slides together, a positioning rod 63 fixed to the lower end of the movable rod 62, a connecting plate 64 fixed to the upper end of the movable rod 62, and a spring 65 that is sleeved on the movable rod 62 and fixed between the bottom of the connecting plate 64 and the top of the fixed plate 61. The lower end of the positioning rod 63 is pressed against the top of the reinforcement rod 3 under the action of the spring 65. A positioning groove 32 is provided on the reinforcement rod 3 for the positioning rod 63 to be plugged in and connected to the inner bottom wall of the transmission inclined groove 31, and the side of the positioning groove 32 away from the pyramid end of the reinforcement rod 3 is connected to the side wall of the reinforcement rod 3 away from its pyramid end.

[0041] When the inclined surface at the bottom of the resistance block 52 is completely separated from the transmission inclined groove 31, the positioning rod 63 moves downward under the pulling force of the spring 65 and engages with the positioning groove 32. The positioning rod 63 has a good limiting effect on the reinforcement rod 3, ensuring the stability of the reinforcement rod 3 after being inserted into the soil and reducing the probability of the reinforcement rod 3 retreating.

[0042] The threaded rod 2 passes through the inner top wall of the vertical mounting hole 13 and is rotatably connected. A mounting plate 7 is provided above the pile base 1. A plurality of support blocks 71 are fixed to the bottom of the mounting plate 7 and are evenly distributed about the central axis of the pile base 1. The drive mechanism 4 includes a transmission assembly 41 and a drive assembly 42. The transmission assembly 41 includes a circular block 411 fixed to the upper end of the threaded rod 2, a transmission shaft 412 that passes through the mounting plate 7 and is rotatably connected, a transmission block 413 fixed to the lower end of the transmission shaft 412, and a driven gear 414 fixedly sleeved on the transmission shaft 412. A transmission groove 4111 is provided at the top of the circular block 411 for the transmission block 413 to be plugged in and matched. The drive assembly 42 is used to drive the driven gear 414 to rotate. The drive assembly 42 includes a driving gear 421 that is rotatably mounted at the center of the mounting plate 7 and meshes with the driven gear 414, and a motor 422 fixed to the mounting plate 7 and used to drive the driving gear 421 to rotate.

[0043] After the motor 422 is activated, it drives the driving gear 421 to rotate, thereby rotating the driven gear 414 meshing with the driving gear 421, the transmission shaft 412 fixed to the driven gear 414, and the transmission block 413 fixed to the lower end of the transmission shaft 412. This causes the round block 411 plugged into the transmission block 413 and the threaded rod 2 fixed to the round block 411 to rotate, ultimately causing the movable plate 51 and the abutment block 52 to descend and complete the operation of extruding the reinforcement rod 3 to reinforce the pile. The mounting plate 7 is detachably connected to the pile base 1 by plugging the transmission block 413 into the transmission groove 4111, so that the mounting plate 7, transmission shaft 412, transmission block 413, driven gear 414, and driving gear 421 can be reused.

[0044] In order to ensure that the pile basic body 1 can be reinforced by the reinforcement rod 3 in all four directions, four vertical mounting holes 13 and four threaded rods 2 are provided and are evenly distributed about the central axis of the pile basic body 1. Four rows of transverse mounting holes 14 are provided in the vertical direction. The four rows of transverse mounting holes 14 are respectively located on the circumferential sides of the central axis of the pile basic body 1. The two rows of transverse mounting holes 14 on the opposite sides of the pile basic body 1 are equal in height. The openings of the two rows of transverse mounting holes 14 on the opposite sides of the pile basic body 1 are respectively located on both sides of the pile basic body 1. The two rows of transverse mounting holes 14 on the adjacent sides of the pile basic body 1 are alternately arranged up and down. The number of reinforcement rods 3 is equal to the number of transverse mounting holes 14 and the positions correspond one to one. The interference assembly 5 is provided with four groups and corresponds to the positions of the four rows of transverse mounting holes 14 respectively. There are four driven gears 414 and they are respectively located on the four threaded rods 2. In this embodiment, the end of the reinforcement rod 3 away from the opening of the transverse mounting hole 14 is located close to the side wall of the pile basic body 1 away from the opening of the transverse mounting hole 14, so that the extendable length of the reinforcement rod 3 is maximized, thereby ensuring the reinforcement effect of the pile basic body 1.

[0045] In order to facilitate the installation of the threaded rod 2, the positioning assembly, the interference assembly 5, etc., the pile base body 1 is composed of a first pile foundation 11 and a second pile foundation 12 that are detachably connected and structurally symmetrical.

[0046] This embodiment also discloses a construction process for a ground anti-settlement structure surrounding a building, comprising the following steps:

[0047] S1. Drive multiple pile basic bodies 1 distributed in a rectangular array into the soil around the ground outside the building, ensuring that the tops of the multiple pile basic bodies 1 are at the same height from the ground;

[0048] S2. Place the mounting plate 7 with the motor 422, the driving gear 421, the transmission shaft 412, the driven gear 414, the transmission block 413, and the support block 71 on the top of the pile basic body 1, and make the transmission block 413 engage with the transmission groove 4111 on the round block 411 on the top of the pile basic body 1;

[0049] S3, start the motor 422, and after the motor 422 works, it drives the driving gear 421 to rotate, so that the four driven gears 414, the transmission shaft 412, the transmission block 413, the round block 411, and the threaded rod 2 all rotate. Since the movable plate 51 is threadedly connected to the threaded rod 2, the two ends of the movable plate 51 respectively abut against the inner walls on both sides of the vertical mounting hole 13, so that the movable plate 51 can be lowered, and the resistance block 52 is synchronously lowered with the movable plate 51. The inclined surface of the bottom of the resistance block 52 is in contact with the inner bottom of the transmission chute 31. The wall abuts and causes the reinforcement rod 3 to gradually pass through the transverse mounting hole 14. When the positioning rod 63 corresponds to the positioning groove 32 on the reinforcement rod 3, under the action of the spring 65, the lower end of the positioning rod 63 is plugged into the positioning groove 32 and limits the reinforcement rod 3. At this time, the movable plate 51 just completely passes through the transmission inclined groove 31. As the motor 422 continues to drive the threaded rod 2 to rotate, the abutment block 52 can squeeze the remaining reinforcement rods 3 out of the transverse mounting hole 14 in turn, thereby improving the connection strength between the pile base body 1 and the soil.

[0050] S4. Backfill the gravel layer and soil layer between the multiple pile basic bodies 1 and compact them until the top of the soil layer is flush with the top of the soil around the building.

[0051] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.

The anti-settlement structure for the ground surrounding a building according to claim 5, characterized in that: The vertical mounting holes (13) and the threaded rod (2) are both provided with four and are evenly distributed about the central axis of the pile basic body (1). The transverse mounting holes (14) are provided in four rows in the vertical direction. The four rows of transverse mounting holes (14) are respectively located on the circumference of the central axis of the pile basic body (1). The two rows of transverse mounting holes (14) on the opposite sides of the pile basic body (1) are equal in height. The openings of the two rows of transverse mounting holes (14) on the opposite sides of the pile basic body (1) are respectively located on both sides of the pile basic body (1). The two rows of transverse mounting holes (14) on the adjacent sides of the pile basic body (1) are alternately arranged up and down. The number of the reinforcement rods (3) is equal to the number of the transverse mounting holes (14) and the positions correspond one to one. The interference assembly (5) is provided with four groups and corresponds to the positions of the four rows of transverse mounting holes (14). The driven gears (414) are provided with four and are respectively located on the four threaded rods (2).

7. The anti-settlement structure for the ground surrounding a building according to claim 6, characterized in that: The pile base body (1) consists of a first pile foundation (11) and a second pile foundation (12) which are detachably connected and structurally symmetrical.

8. A building perimeter ground anti-settlement structure and construction process according to any one of claims 1 to 7, characterized in that: The steps include: S1. driving a plurality of pile basic bodies (1) distributed in a rectangular array into the soil around the outer ground of the building, ensuring that the tops of the plurality of pile basic bodies (1) are at the same height from the ground; S2, placing a mounting plate (7) with a motor (422), a driving gear (421), a transmission shaft (412), a driven gear (414), a transmission block (413), and a support block (71) on the top of the pile basic body (1), and making the transmission block (413) engage with the transmission groove (4111) on the round block (411) on the top of the pile basic body (1); S3, start the motor (422), and after the motor (422) works, it drives the driving gear (421) to rotate, thereby causing the four driven gears (414), the transmission shaft (412), the transmission block (413), the round block (411), and the threaded rod (2) to rotate. Since the movable plate (51) is threadedly connected to the threaded rod (2), the two ends of the movable plate (51) respectively contact the inner walls of the two sides of the vertical mounting hole (13), so that the movable plate (51) can be lowered, and the contact block (52) is synchronously lowered with the movable plate (51). The inclined surface of the bottom of the contact block (52) is aligned with the inner bottom of the transmission inclined groove (31). The wall abuts and causes the reinforcing rod (3) to gradually pass through the transverse mounting hole (14). When the positioning rod (63) corresponds to the positioning groove (32) on the reinforcing rod (3), under the action of the spring (65), the lower end of the positioning rod (63) is plugged into the positioning groove (32) and limits the reinforcing rod (3). At this time, the movable plate (51) just completely passes through the transmission inclined groove (31). As the motor (422) continues to drive the threaded rod (2) to rotate, the abutment block (52) can squeeze the remaining reinforcing rods (3) out of the transverse mounting hole (14) in turn, thereby improving the connection strength between the pile basic body (1) and the soil. S4. Backfill the gravel layer and soil layer between the multiple pile basic bodies (1) and compact them until the top of the soil layer is flush with the top of the soil around the building.
