Description

Technical Field

[0001] This utility model relates to an adjustment device, and more particularly to an anchor-pull pile stress dispersion adjustment device. Background Technology

[0002] The anchored pile stress dispersion adjustment device dynamically adjusts the anchor cable tension and pile stress distribution to avoid local stress concentration in the support structure, thereby improving the safety and stability of the foundation pit support system. It can adapt to soil deformation and load changes, effectively control foundation pit displacement, reduce the risk of pile cracking and anchor cable failure, and at the same time improve material reuse rate and reduce construction costs. It plays an important role in promoting deep foundation pit engineering and green construction under complex geological conditions.

[0003] The stress dispersion and adjustment device for anchored piles receives lateral soil pressure through the piles and transmits it to the anchored stratum via anchor cables. Stress sensors within the device monitor the stress in real time. When local stress exceeds the limit, the tension of the steel cables is adjusted. The concentrated load is distributed to multiple support points through load-sharing components. The flexible transmission of adjustable nodes adapts to soil deformation and dynamically redistributes stress, avoiding local overload of the piles and ensuring stress balance in the support system during foundation pit construction, thereby improving structural safety and stability.

[0004] In existing technologies, some anchor-driven pile stress dispersion and adjustment devices are not convenient for fixing the anchor cable to adjust the stress more quickly when adjusting the stress, which leads to local stress concentration and may cause the pile or anchor rod to fail due to overload. Therefore, an anchor-driven pile stress dispersion and adjustment device is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a stress dispersion and adjustment device for anchored piles. The purpose is to improve the problem in the prior art where the inconvenience of fixing the anchor cable to adjust the stress more quickly leads to local stress concentration, which may cause the pile or anchor rod to fail due to overload.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anchored pile stress dispersion and adjustment device includes a pile, with an anchor plate detachably connected to the top of the pile. The inner wall of the anchor plate has multiple holes, and clamps are slidably connected to the holes of the anchor plate. An anchor cable is slidably connected to the outer wall of the clamp, and a pressure plate is slidably connected to the outer wall of the anchor cable. Two cylinders are fixedly connected to the top of the pressure plate, and a connecting plate is fixedly connected to the driving end of the two cylinders. A fixing component for fixing is installed on the top of the connecting plate.

[0008] Preferably, the aforementioned fixing component includes a base plate, the bottom of which is detachably connected to the top of a connecting plate, a plurality of side plates being detachably connected to the top of the base plate, and two positioning plates being detachably connected to the top of the base plate.

[0009] Preferably, the inner wall of the connecting plate is provided with multiple holes, and each of the holes in the multiple connecting plates can be detachably connected to another clip.

[0010] Preferably, the outer wall of the anchor cable is installed on the inner wall of the pile, and the bottom of the pressure plate is in contact with the top of the wedge.

[0011] Preferably, the inner wall of the pressure plate is provided with multiple holes, and anchor cables are slidably connected in the holes of the multiple pressure plates.

[0012] Preferably, the inner walls of the four side plates are provided with holes, and the inner walls of the two positioning plates are provided with holes.

[0013] Preferably, the hole in the side plate is threaded with a screw, and the outer wall of the screw is threaded into the hole in the positioning plate.

[0014] Preferably, the outer walls of the aforementioned multiple side plates are detachably connected to fixing blocks, and the inner walls of the fixing blocks are detachably connected to support rods.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] This invention utilizes a cylinder that, upon activation, pushes the connecting plate upwards, thereby lifting the anchor cable and distributing and adjusting stress. When the desired value is reached, the cylinder is deactivated, and the connecting plate, pressure plate, and cylinder are removed, completing the stress distribution and adjustment of the anchor cable. This prevents the structural safety reserve from decreasing due to changes in soil parameters or sudden loads, thus reducing the risk of cracking and excessive displacement in the support system.

[0017] This utility model fixes the side plates and positioning plates to the base plate surface with screws, then connects the support rod to the fixing block, and then connects the fixing block to the side plates, so that the side plates and positioning plates are firmly on the base plate. Finally, the base plate is poured to complete the support. This prevents the complex installation process from increasing the amount of wet work on site, causing quality problems such as incomplete concrete pouring, which would require rework and repair later.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 2 and Figure 3 This utility model discloses a stress dispersion and adjustment device for anchored piles, comprising piles 1 for installing anchor cables 4. An anchor plate 2 is detachably connected to the top of the piles 1 for fixing the anchor cables 4. The inner wall of the anchor plate 2 has multiple holes, and clamping pieces 3 are slidably connected to each hole of the anchor plate 2 for holding the anchor cables 4. The outer wall of the clamping pieces 3 is slidably connected to the anchor cables 4 for providing tension, fixing the piles 1, and controlling deformation. The outer wall of the anchor cables 4 is slidably connected to a pressure plate 5 for pressing the clamping pieces 3. Two cylinders 6 are fixedly connected to the top of the pressure plate 5. The cylinders 6 are used to connect the plate 7 to adjust the stress of the anchor cables 4, while the pressure plate 5 presses the clamping pieces 3 to prevent the anchor cables 4 from slipping during the adjustment process. The driving ends of the two cylinders 6 are fixedly connected to the connecting plate 7 for adjusting the stress of the anchor cables 4. The top of the connecting plate 7 is equipped with a fixing component for fixing.

[0026] The inner wall of the connecting plate 7 has multiple holes, and another clamping piece 3 can be detachably connected to each of the holes of the connecting plate 7. The outer wall of the anchor cable 4 is installed on the inner wall of the pile 1. The bottom of the pressure plate 5 is in contact with the top of the clamping piece 3. The inner wall of the pressure plate 5 has multiple holes, and the anchor cable 4 is slidably connected to each of the holes of the pressure plate 5.

[0027] Reference Figure 1 and Figure 4The fixing assembly includes a base plate 8, which is used for concrete pouring. The bottom of the base plate 8 is detachably connected to the top of the connecting plate 7. Multiple side plates 9 are detachably connected to the top of the base plate 8, which are used to fix the base plate 8. Two positioning plates 10 are detachably connected to the top of the base plate 8, which are used to form a container for concrete pouring with the side plates 9 and the base plate 8. Holes are opened in the inner walls of the four side plates 9 and the two positioning plates 10. Screws 11 are threaded into the holes of the side plates 9, which are used to fix the side plates 9 and the positioning plates 10. The outer walls of the screws 11 are threaded into the holes of the positioning plates 10. Fixing blocks 12 are detachably connected to the outer walls of the multiple side plates 9, which are used to connect the multiple side plates 9. Support rods 13 are detachably connected to the inner walls of the fixing blocks 12, which are used to prevent the concrete from falling during pouring.

[0028] The working principle of this utility model is as follows: When it is necessary to disperse and adjust the stress of the anchor cable 4, the anchor cable 4 is placed inside the pile 1, and then the anchor plate 2 is placed on the upper surface of the pile 1, so that the clamping piece 3 is inserted into the gap between the anchor plate 2 and the anchor cable 4. At this time, the pressure plate 5 is brought into contact with the clamping piece 3, and then the driving end of the cylinder 6 is installed with the connecting plate 7, so that the clamping piece 3 is inserted into the gap between the connecting plate 7 and the anchor cable 4. At this time, the cylinder 6 is started, and then the driving end of the cylinder 6 pushes the connecting plate 7 to move upward, so that the anchor cable 4 is pulled upward, and the stress of the anchor cable 4 is dispersed and adjusted at the same time. When the required value is reached, the cylinder 6 is closed, so that the connecting plate 7, the pressure plate 5 and the cylinder 6 are removed, thereby completing the stress dispersion and adjustment of the anchor cable 4, preventing the local stress concentration caused by soil deformation during foundation pit excavation, which could lead to overload failure of the pile 1 or the anchor cable 4.

[0029] When the support needs to be poured after the stress dispersion adjustment of the anchor cable 4, the base plate 8 is placed on the anchor cable 4, and then the side plate 9 and the positioning plate 10 are fixed on the surface of the base plate 8, so that the side plate 9 and the positioning plate 10 are connected together by screws 11. At this time, the support rod 13 is connected to the fixing block 12, and then the fixing block 12 is connected to the side plate 9, so that the side plate 9 and the positioning plate 10 are fixed on the base plate 8. At this time, the support can be poured on the base plate 8 to complete the support. This prevents the positioning deviation of the pile 1 and the anchor angle error from exceeding the allowable range due to the difficulty of installation, which would affect the stress performance of the support structure and reduce the overall stability.
