Description

Technical Field

[0001] This application relates to the field of slope reinforcement technology, and in particular to an adjustable-angle foundation pit slope support structure. Background Technology

[0002] Slope protection for foundation pits is a crucial aspect of ensuring the safety of foundation pit construction and the stability of the surrounding environment. With the continuous development of urban construction, the scale and complexity of foundation pit projects are increasing, placing higher demands on the performance and adaptability of foundation pit slope protection structures. A reasonable and effective foundation pit slope protection structure can prevent geological disasters such as slope collapse and landslides, protect the safety of construction personnel and equipment within the foundation pit, and reduce the impact on surrounding buildings and underground pipelines.

[0003] There are several conventional methods for solving the problem of foundation pit slope support. A common method is to use traditional fixed-angle retaining plates. These plates are manufactured with a fixed inclination angle and are fixed during construction using pile foundations driven into the ground. Specifically, the retaining plates are arranged sequentially according to design requirements and then connected to the pile foundations to provide support for the foundation pit slope. Another method is to use concrete retaining walls. During construction, formwork is first erected, and then concrete is poured at the edge of the foundation pit. After the concrete hardens, a continuous wall structure is formed, relying on the strength and stability of the wall to prevent the slope soil from sliding. Additionally, soil nailing walls are also a commonly used method. The construction process involves drilling holes in the slope soil, inserting reinforcing bars, and then injecting cement mortar to form soil nails. This allows the soil to bond with the soil nails, utilizing the friction between the soil nails and the soil to enhance soil stability.

[0004] Regarding the aforementioned technologies, sheet pile support is difficult to drive when encountering hard soil or rock layers, and its fixed support angle makes it difficult to adapt to foundation pit slopes with different inclinations. Utility Model Content

[0005] To overcome the above problems, this application provides an adjustable-angle foundation pit slope support structure.

[0006] The adjustable-angle foundation pit slope support structure provided in this application adopts the following technical solution: An adjustable-angle foundation pit slope support structure includes a fixing component, a splicing component, and a driving component. The fixing component includes a base fixed to the bottom of the foundation pit. The splicing component includes at least one support plate, which is arranged along the slope direction. The lower side of the support plate is rotatably connected to the base. The support plate can rotate towards or away from the slope. The support plate supports the slope. The driving component is connected to the base and to the support plate to drive the support plate to rotate.

[0007] By adopting the above technical solution, the base of the fixed component is fixed to the bottom of the foundation pit, providing stable support for the entire support structure and ensuring its stability. The support plate of the splicing component is rotatably connected to the base and can rotate to the side away from or closer to the slope, thus supporting the slope. The driving component is connected to the base and the support plate, which can drive the support plate to rotate, allowing the support structure to flexibly adjust the angle according to the actual slope inclination, improving the support effect. Compared with the traditional fixed-angle support structure, it has stronger adaptability and flexibility, better meeting the support needs of different foundation pit slopes, reducing the problem of poor support effect caused by irregular slope inclination, and reducing construction costs and difficulty. It is also conducive to adapting to foundation pit slope support with different inclinations.

[0008] In one specific implementation, the drive assembly includes a transmission component and a drive component. The transmission component includes a support rod and a pulley. The support rod is arranged along the axis of the pit and is connected to the base. The pulley is rotatably connected to the top of the support rod. The driving component includes a driving frame, a collecting roller, and a pull rope. The driving frame is connected to the base and is located on the side of the support rod away from the support plate. The collecting roller is rotatably connected to the driving frame and is arranged in a direction parallel to the slope. The axis of the collecting roller is perpendicular to the support rod. One end of the pull rope is fixed to the collecting roller, and the other end is wound around the pulley and connected to the side of the support plate away from the base.

[0009] By adopting the above technical solution, and utilizing the support rod and pulley of the transmission component, as well as the drive frame, collection roller and pull rope of the drive component, rotating the collection roller can pull the support plate to rotate through the pull rope, thereby realizing the adjustment of the support plate angle and enabling support for slopes with different inclinations.

[0010] In one specific implementation, the transmission component further includes a drive seat, which is detachably connected to the top of the base, and the support rod and the drive frame are both connected to the drive seat; The drive unit also includes a hook and a hanging ring. The end of the pull rope away from the collecting roller is fixed to the hook, and the hanging ring is fixed to the side of the support plate away from the base. The hook and the hanging ring can be hooked together.

[0011] By adopting the above technical solution, the drive seat can be detachably connected to the top of the base, which facilitates the installation and disassembly of the drive components, and makes maintenance and replacement convenient. The setting of hooks and hanging rings makes the connection between the pull rope and the support plate more flexible, and can quickly realize the connection and separation of the pull rope and the support plate. It is convenient to store the pull rope, which helps to reduce the damage to the pull rope during long-term slope support.

[0012] In one specific implementation, four support plates are provided, which are spliced ​​together to form a support plate. The support plate is set along the inclination direction of the slope. The four support plates are distributed along the length direction of one side of the support plate. A strip is fixed to one side of the support plate. The strip is set along the length direction of the side of the support plate it is located on. A slot is opened on the other side of the support plate for the strip on the adjacent support plate to be inserted. The strip fits into the slot. The splicing assembly also includes multiple fasteners, with a fastener provided at the connection point of two adjacent support plates, the fastener being used to fix the two adjacent support plates.

[0013] By adopting the above technical solution, four support plates are spliced ​​together to form a support plate, which can flexibly adapt to slopes of different lengths; the insertion strips and slots fit together and the fasteners fix adjacent support plates, ensuring the stability of the support plate structure and providing better slope support.

[0014] In one specific implementation, the support rod includes a plug rod, a slide rod, and an insertion screw. The plug rod is connected to the base, and the slide rod is coaxially arranged with the plug rod. The slide rod is inserted into the end of the plug rod away from the base and is slidably connected to the plug rod along its length. The end of the plug rod away from the base has a plug hole, and the end of the slide rod near the plug rod has multiple insertion holes corresponding to the plug hole along its length. Personnel adjust the slide rod to a suitable position according to the size of the support plate. The insertion screw passes through the plug hole and the insertion hole in sequence and is threadedly connected to the plug rod and the slide rod in sequence.

[0015] By adopting the above technical solution, the support rod uses a combination of insert rod, sliding rod and insert screw. Personnel can adjust the position of the sliding rod according to the size of the support plate and then fix it with insert screw. This allows the transmission components to better adapt to support plates of different sizes, further enhancing the adaptability and flexibility of the support structure to different foundation pit slopes.

[0016] In one specific implementation, a rotating assembly is further included. The rotating assembly includes a rotating component and two snap-fit ​​components. The rotating component includes a rotating rod, two fixed seats, and a rotating cylinder. The rotating rod is located near one side of the base and is arranged along the length direction of the side of the base where it is located. The two fixed seats are distributed along the length direction of the rotating rod. The rotating rod passes through the fixed seats and is fixed to the fixed seats. The fixed seats are fixed to the base. The rotating cylinder is fixed to the support plate near the base and is sleeved on the rotating rod. Each end of the rotating cylinder contacts one of the fixed seats and is rotatably connected to the rotating rod. Two snap-fit ​​components correspond one-to-one with the two ends of the rotating rod. The rotating rod has snap-fit ​​grooves along its length. The fixed base has through slots that communicate with the snap-fit ​​grooves. Each snap-fit ​​component includes a snap-fit ​​strip located within the snap-fit ​​groove. The snap-fit ​​strip is oriented in the same direction as the snap-fit ​​groove. The snap-fit ​​strip is slidably connected to the rotating rod along its length. The inner wall of the rotating cylinder near the fixed base has multiple fixing slots along its length. These fixing slots are evenly distributed around the circumference of the rotating cylinder. When the support plate is adjusted to a suitable position, the snap-fit ​​strip is driven to slide, and the snap-fit ​​strip passes through the through slots and fixing slots in sequence to snap the rotating cylinder in place.

[0017] By adopting the above technical solution, the rotating component of the rotating assembly enables the support plate to rotate around the rotating rod, which facilitates angle adjustment. When the support plate is adjusted to the appropriate position, the locking strip of the locking component can pass through the through slot and the fixing slot to lock the rotating cylinder, preventing the rotating cylinder from rotating and ensuring the stability of the support plate after angle adjustment.

[0018] In one specific implementation, the snap-fit ​​component further includes a placement seat, a rack, a gear, a drive rod, and a fixing screw. The placement seat is connected to the end of the rotating rod. The placement seat has a receiving cavity for accommodating the gear. The rack is oriented in the same direction as the snap-fit ​​strip. One end of the rack is connected to the snap-fit ​​strip, and the other end passes through the placement seat and extends into the receiving cavity to mesh with the gear. The drive rod passes through the placement seat and extends into the receiving cavity to be coaxially fixed with the gear. The drive rod is rotatably connected to the placement seat. The placement seat has a fixing hole on the side wall through which the drive rod passes. The fixing hole extends through the placement seat along the length of the drive rod. The gear has multiple snap-fit ​​holes corresponding to the fixing holes in its circumferential direction. When the gear drives the snap-fit ​​strip to a suitable position, the fixing screw passes through the fixing hole and the snap-fit ​​hole in sequence, and the fixing screw is threadedly connected to the placement seat and the gear in sequence.

[0019] By adopting the above technical solution, the operator rotates the drive rod, which drives the locking strip to move through the meshing of the gear and rack. This allows the locking strip to pass through the through slot and the fixing slot to lock the rotating cylinder, thereby fixing the angle of the support plate. At the same time, the fixing screw can fix the gear to prevent the gear from rotating and ensure the stability of the support plate after the angle is adjusted.

[0020] In one specific implementation, the snap-fit ​​component further includes a second screw, which is close to the snap-fit ​​groove. The second screw is oriented in the same direction as the snap-fit ​​groove. The second screw passes through the rotating rod and extends into the snap-fit ​​groove to be rotatably connected to the snap-fit ​​strip. The second screw is threadedly connected to the rotating rod.

[0021] By adopting the above technical solution, personnel can drive the locking strip to move by turning the second screw, thereby conveniently locking or unlocking the rotating cylinder, further improving the convenience of angle adjustment and fixation of the support structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed adjustable-angle foundation pit slope support structure features a support plate rotatably connected to the base of the splicing components, which can rotate towards or away from the slope to provide slope support. The drive component is connected to the base and the support plate, allowing the support plate to rotate. This enables the support structure to flexibly adjust its angle according to the actual slope inclination, improving the support effect. Compared with traditional fixed-angle support structures, it has stronger adaptability and flexibility, better meeting the support needs of different foundation pit slopes. It reduces the problem of poor support effect caused by irregular slope inclination, while also reducing construction costs and difficulty, and is conducive to adapting to foundation pit slope support with different inclinations.

[0023] 2. The designed adjustable-angle foundation pit slope support structure utilizes the support rods and pulleys of the transmission components, as well as the drive frame, collection rollers, and pull ropes of the drive components. Rotating the collection rollers can pull the support plates to rotate via the pull ropes, thereby achieving the adjustment of the support plate angle and enabling support for slopes with different inclinations.

[0024] 3. The designed adjustable-angle foundation pit slope support structure consists of three support plates spliced ​​together to form a support plate, which can flexibly adapt to slopes of different lengths; the interlocking of inserts and slots and the fixing parts fix adjacent support plates, ensuring the stability of the support plate structure and providing better slope support.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses an adjustable-angle foundation pit slope support structure.

[0035] Reference Figure 1 An adjustable-angle foundation pit slope support structure includes a fixed component 1, a splicing component 2, a rotating component 3, and a driving component 4. The splicing component 2 is connected to the fixed component 1 through the rotating component 3, and the driving component 4 is located on the fixed component 1.

[0036] Reference Figure 1 and Figure 2The fixing component 1 includes a base 11 and multiple anchors 12, all located on one side of the base 11. In this embodiment, there are four anchors 12 arranged in a matrix. Each anchor 12 includes an anchor cylinder 121, multiple insertion pins 122, multiple springs 123, a conical pusher block 124, and a first screw 125. The anchor cylinder 121 is perpendicular to the base 11 and welded to it. The anchor cylinder 121 is hollow, with a pointed end away from the base 11 for easy insertion into the ground. In this embodiment, there are four insertion pins 122, evenly distributed around the circumference of the anchor cylinder 121. The insertion pins 122 are arranged perpendicular to the axis of the anchor cylinder 121. 2 One end of the insertion pin 122 is inserted through the side wall of the anchoring cylinder 121. The end of the insertion pin 122 away from the axis of the anchoring cylinder 121 is pointed. The insertion pin 122 is slidably connected to the anchoring cylinder 121. When the anchoring cylinder 121 is inserted into the ground, the insertion pin 122 moves away from the axis of the anchoring cylinder 121. The pointed end of the insertion pin 122 can be inserted into the soil, which can increase the stability of the base 11. The spring 123 corresponds to the insertion pin 122. The spring 123 is sleeved on the end of the insertion pin 122 located inside the anchoring cylinder 121. One end of the spring 123 is welded to the side wall of the anchoring cylinder 121, and the other end is welded to the insertion pin 122. When the spring 123 is in the initial state, that is, the spring 123 has not deformed, at this time, the pointed end of the insertion pin 122 is flush with the outer wall of the anchoring cylinder 121, which makes it easy for the anchoring cylinder 121 to be inserted into the ground.

[0037] Reference Figure 1 and Figure 2 A conical pusher block 124 is located inside the anchoring cylinder 121. The diameter of the conical pusher block 124 gradually decreases from the base 11 to one side of the anchoring cylinder 121. The conical pusher block 124 is slidably connected to the anchoring cylinder 121 along its axis. The insertion pin 122 abuts against the side wall of the conical pusher block 124 near the axis of the anchoring cylinder 121. A first screw 125 is arranged along the axis of the anchoring cylinder 121. The first screw 125 passes through the base 11 and extends into the anchoring cylinder 121. After 21, it is rotatably connected to the conical pusher block 124. The first screw 125 is sequentially threaded to the base 11 and the anchor cylinder 121. A handle is welded to the top of the first screw 125. When the anchor cylinder 121 is inserted into the ground, the personnel rotate the first screw 125, which pushes the insertion pin 122 to move through the conical pusher block 124, so that the insertion pin 122 can be inserted into the soil. The base 11 is fixed to the ground by the anchor 12, which ensures the stability of the entire support structure.

[0038] Reference Figure 1 and Figure 3The splicing assembly 2 includes at least one support plate 21 and multiple fasteners 22. The number of support plates 21 is determined according to the actual situation to facilitate slope support. In this embodiment, there are four support plates 21, which are spliced ​​together to form a support plate. The support plate is set along the inclination direction of the slope, and the four support plates 21 are distributed along the length direction of one side of the support plate 21. A strip 211 is welded to one side of the support plate 21, and the strip 211 is set along the length direction of the side of the support plate 21 it is located on. The other side of the support plate 21 has a fastener for adjacent fasteners. The insert 211 on the support plate 21 is inserted into the slot 212, and the insert 211 fits into the slot 212. A fastener 22 is provided at the connection between two adjacent support plates 21. The fastener 22 includes multiple bolts 221. In this embodiment, there are three bolts 221. The three bolts 221 are distributed at intervals along the length direction of the insert 211. The bolts 221 are sequentially inserted into the support plate 21 and the insert 211. The bolts 221 are sequentially threaded to the support plate 21 and the insert 211. The two adjacent support plates 21 can be fixed by the bolts 221.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The rotating assembly 3 includes a rotating member 31 and two snap-fit ​​members 32. The rotating member 31 includes a rotating rod 311, two fixed seats 312, and a rotating cylinder 313. The rotating rod 311 is located near one side of the base 11 and is arranged along the length of the side of the base 11. The two fixed seats 312 are distributed along the length of the rotating rod 311. The rotating rod 311 passes through the fixed seats 312 and is welded to the fixed seats 312. The fixed seats 312 are welded to the base 11. The base 11 has a rotating cylinder 313 located on the side of the support plate near the base 11. The rotating cylinder 313 is set along the length of the side of the support plate 21 where it is located. The rotating cylinder 313 is welded to the support plate 21 and sleeved on the rotating rod 311. The rotating cylinder 313 is located between two fixed seats 312. Each end of the rotating cylinder 313 is in contact with a fixed seat 312. The rotating cylinder 313 is rotatably connected to the rotating rod 311. The support plate rotates synchronously with the rotating cylinder 313 in order to adjust the tilt angle of the support plate.

[0040] Reference Figure 4 and Figure 5Two snap-fit ​​pieces 32 correspond one-to-one with the two ends of the rotating rod 311. In one embodiment, the snap-fit ​​piece 32 includes a snap-fit ​​strip 321, a placement seat 322, a rack 323, a gear 324, a drive rod 325, and a fixing screw 326. The rotating rod 311 has a snap-fit ​​groove 3111, which is set along the length of the rotating rod 311. The fixing seat 312 has a through groove 3121 corresponding to the snap-fit ​​groove 3111, which communicates with the snap-fit ​​groove 3111. The snap-fit ​​strip 321 is located in the snap-fit ​​groove 3111, and the setting direction of the snap-fit ​​strip 321 is consistent with the setting direction of the snap-fit ​​groove 3111. The snap-fit ​​strip 321 is set along the length of the rotating rod 311. The directional sliding connection is to the rotating rod 311. The through groove 3121 allows the locking strip 321 to pass through. The inner wall of the rotating cylinder 313 near the fixed seat 312 has multiple fixing grooves 3131. The fixing grooves 3131 are arranged along the length of the rotating cylinder 313 and are evenly distributed around the circumference of the rotating cylinder 313. When the support plate is adjusted to a suitable position, the fixing grooves 3131 can communicate with the through groove 3121. When the support plate is adjusted to a suitable position, the locking strip 321 is driven to slide, so that the locking strip 321 passes through the through groove 3121 and the fixing groove 3131 in sequence, which can lock the rotating cylinder 313, prevent the rotating cylinder 313 from rotating, and ensure the stability of the support plate after the angle is adjusted.

[0041] Reference Figure 4 and Figure 5 The placement seat 322 is welded to the end of the rotating rod 311. The rack 323 is located in the snap-fit ​​groove 3111, on the side of the snap-fit ​​strip 321 away from the fixed seat 312. The rack 323 is set in the same direction as the snap-fit ​​strip 321. One end of the rack 323 is welded to the snap-fit ​​strip 321. The placement seat 322 has a receiving cavity for the gear 324. The other end of the rack 323 passes through the placement seat 322 and extends into the receiving cavity. The gear 324 meshes with the rack 323. The drive rod 325 passes through the placement seat 322 and extends into the receiving cavity, where it is coaxially welded with the gear 324. The drive rod 325 is rotatably connected to the placement seat 322. When a person rotates the drive rod 325, the gear 324 and the rack 323 mesh. The engagement of bar 323 drives the movement of the snap-fit ​​bar 321. The placement seat 322 has a fixing hole on the side wall through which the drive rod 325 passes. The fixing hole extends through the placement seat 322 along the length of the drive rod 325. The gear 324 has multiple snap-fit ​​holes 3241 corresponding to the fixing hole in its circumference. When the gear 324 drives the snap-fit ​​bar 321 to a suitable position, the fixing screw 326 passes through the fixing hole and the snap-fit ​​hole 3241 in sequence. The fixing screw 326 is threaded to the placement seat 322 and the gear 324 in sequence. The fixing screw 326 can fix the gear 324 and prevent the gear 324 from rotating. When the gear 324 needs to rotate, the fixing screw 326 can be separated from the gear 324.

[0042] Reference Figure 6 In another embodiment, the snap-fit ​​component 32 further includes a second screw 327. The second screw 327 is close to the snap-fit ​​groove 3111, and the setting direction of the second screw 327 is consistent with the setting direction of the snap-fit ​​groove 3111. The second screw 327 passes through the rotating rod 311 and extends into the snap-fit ​​groove 3111 to be rotatably connected to the snap-fit ​​strip 321. The second screw 327 is threadedly connected to the rotating rod 311. By turning the second screw 327, the operator can drive the snap-fit ​​strip 321 to move.

[0043] Reference Figure 7 The drive assembly 4 includes a transmission component 41 and a drive component 42. The transmission component 41 includes a drive seat 411, a support rod 412, and a pulley 413. The top of the base 11 has a placement groove 111, and the drive seat 411 is located in the placement groove 111. The drive seat 411 is detachably connected to the base 11 by reinforcing screws. The support rod 412 includes an insertion rod 4121, a sliding rod 4122, and an insertion screw 4123. The insertion rod 4121 is welded to the top of the drive seat 411 and is perpendicular to the base 11. The sliding rod 4122 is coaxial with the insertion rod 4121 and is inserted into the end of the insertion rod 4121 away from the drive seat 411. The sliding rod 4122 is slidably connected to the insertion rod 4121 along its length. 21. The insertion rod 4121 has an insertion hole at the end away from the drive seat 411. The slide rod 4122 has multiple insertion holes corresponding to the insertion hole at the end near the insertion rod 4121. The multiple insertion holes are distributed along the length of the slide rod 4122. When the operator adjusts the slide rod 4122 to a suitable position according to the size of the support plate, the insertion screw 4123 passes through the insertion hole and the insertion hole in sequence. The insertion screw 4123 is threaded to the insertion rod 4121 and the slide rod 4122 in sequence. The insertion screw 4123 can fix the insertion rod 4121 and the slide rod 4122, which can increase the stability of the insertion rod 4121 and the slide rod 4122. The pulley 413 is located at the end of the slide rod 4122 away from the insertion rod 4121, and the pulley 413 is rotatably connected to the slide rod 4122.

[0044] Reference Figure 7The driving component 42 includes a driving frame 421, a collecting roller 422, a pull rope 423, a hook 424, and a hanging ring 425. The driving frame 421 is fixedly connected to the top of the driving base 411 by screws, and the driving frame 421 is located on the side of the insertion rod 4121 away from the support plate. The collecting roller 422 is rotatably connected to the driving frame 421, and the setting direction of the collecting roller 422 is consistent with the setting direction of the rotating rod 311. One end of the pull rope 423 is fixed to the collecting roller 422, and the other end is fixedly connected to the hook 424 by binding. The pull rope 423 is wound around the pulley 413. The hanging ring 425 is located away from the support plate from the base 1. 1. One side is fixedly connected, with hook 424 and hanging ring 425 hooked together, which can quickly connect and separate the pull rope 423 from the support plate 21, making it easy to store the pull rope 423 and reducing the possibility of damage to the pull rope 423 during long-term slope support. When it is necessary to adjust the tilt angle of the support plate, the personnel select the appropriate number of support plates 21 according to the actual working conditions, connect them into a support plate, connect hook 424 and hanging ring 425, and rotate the collection roller 422. The personnel can pull the support plate to rotate through the pull rope 423, thereby adjusting the tilt angle of the support plate, which can support slopes with different inclinations.

[0045] The implementation principle of the adjustable-angle foundation pit slope support structure in this embodiment is as follows: The adjustable-angle foundation pit slope support structure of this embodiment uses a fixing component 1 to firmly fix the base 11 to the ground, ensuring the stability of the entire support structure. The splicing component 2 can flexibly splice the support plate 21 according to actual needs, adapting to slopes of different lengths. The cooperation of the rotating component 3 and the driving component 4 enables the support structure to flexibly adjust the angle according to the actual slope inclination, improving the support effect. Compared with the traditional fixed-angle support structure, it has stronger adaptability and flexibility, can better meet the support needs of different foundation pit slopes, reduces the problem of poor support effect caused by irregular slope inclination, and at the same time reduces construction costs and difficulty.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
