Description

Technical Field

[0001] This invention belongs to the field of pile foundation testing technology, specifically referring to a construction pile foundation testing device for building engineering. Background Technology

[0002] In the construction of pile foundations for building engineering, the horizontal load bearing capacity is a core indicator for evaluating the stability of the pile structure and is directly related to the safety of the superstructure. Therefore, pile foundation horizontal load testing is an indispensable and crucial step in the construction process. The current mainstream testing method in the industry requires the use of reaction support structures to provide stable support for the load application equipment in order to achieve accurate pressure application and strength testing of the pile under test. However, existing reaction support schemes generally suffer from problems such as cumbersome operation and low efficiency.

[0003] Traditional methods often involve casting concrete reaction piles on-site next to the pile foundation to be tested, using these piles to provide reaction force for jacks to apply pressure. However, this method is complex, requiring the reaction piles to be cast in advance and allowed to fully harden, consuming significant preparation time. Disassembling the reaction piles after testing is difficult, increasing construction complexity and potentially leading to material waste and site contamination. While some scenarios use steel beams instead of cast-in-place reaction piles, this requires excavating a strip-shaped foundation pit beforehand, then using a crane to hoist the heavy beams into the pit for positioning and fixation. This cumbersome process is highly dependent on construction equipment, making it particularly difficult to conduct efficiently in confined spaces, ultimately reducing the overall efficiency of pile foundation testing. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a construction pile foundation testing device for building engineering, which effectively solves the above problems.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a construction pile foundation testing device, including a quick-installation reaction pile, a horizontal load application component, a pile body to be tested, and a displacement detection component. The pile body to be tested is poured into a designated soil layer. The displacement detection component is set on one side of the pile body to be tested. The horizontal load application component is vertically mounted on one end of the quick-installation reaction pile and is used to apply a lateral load to the pile body to test its structural strength. The quick-installation reaction pile is set on the other side of the pile body to be tested. The quick-installation reaction pile can be detachably installed in a preset foundation pit. The quick-installation reaction pile includes a hydraulic pushing device, a trigger deployment component, and a lateral reaction pile. Through the cooperation of the hydraulic pushing device and the trigger deployment component, the quick-installation reaction pile is quickly installed in the preset foundation pit while the deployment of the lateral reaction pile is controlled to further increase the installation stability.

[0006] Furthermore, the quick-installation reaction pile is divided into an upper chamber and a lower chamber by a partition. The hydraulic pusher is located in the lower chamber. The hydraulic pusher is connected to a pressing pusher plate by a hydraulic pusher rod. The pressing pusher plate is telescopically located in the first groove, which is opened at the bottom of one end of the quick-installation reaction pile. The hydraulic pusher is used to push the quick-installation reaction pile towards one end of the preset foundation pit to achieve rapid fixation.

[0007] Furthermore, the trigger deployment assembly can be extended and disposed at the other end of the quick-installation reaction pile, and is used to trigger the deployment of the transverse reaction pile through relative compressive force. The trigger deployment assembly includes a pressure-bearing push plate, a pressure-bearing push rod, a deployment connecting rod, and a pressure-bearing guide rod. The pressure-bearing push plate is telescopically disposed in the second groove, which is opened on the surface of the other end of the quick-installation reaction pile. One end of the pressure-bearing push rod is welded and fixed to the pressure-bearing push plate, and the other end of the push rod movably passes through the second groove and extends into the upper cavity. The other end of the push rod is fixedly connected to a connecting part. The deployment connecting rod is symmetrically disposed on both sides of the connecting part. One end of the connecting rod is rotatably connected to the connecting part, and the other end of the connecting rod is rotatably connected to the surface of the transverse reaction pile. Multiple pressure-bearing guide rods are disposed on both sides of the pressure-bearing push plate. One end of the guide rod is fixedly connected to the pressure-bearing push plate, and the other end of the guide rod movably passes through the second groove and is provided with a limit structure. A return spring is sleeved on the guide rod. One end of the return spring abuts against the pressure-bearing push plate, and the other end abuts against the surface of the second groove.

[0008] Furthermore, the transverse reaction piles are telescopically installed on both sides of the quick-installation reaction pile. The transverse reaction piles are provided with sliding connection parts on both sides, and the sliding connection parts are slidably connected with displacement guide rods. The displacement guide rods are fixedly installed on the inner wall of one side of the quick-installation reaction pile. The quick-installation reaction piles are provided with expansion openings on both sides, and the transverse reaction piles are telescopically installed in the expansion openings. The transverse reaction piles are used to insert into the soil layers on both sides of the pre-set foundation pit and further compress them, increasing the overall structural strength and counter-thrust force of the structure, and preventing the quick-installation reaction piles from displacing due to the reaction force.

[0009] Furthermore, one end of the transverse reaction pile is provided with an inclined surface, which is set in the direction of the reaction force, so that the transverse reaction pile can be inserted into the soil layers on both sides.

[0010] Furthermore, the quick-installation reaction pile is equipped with a locking component to lock the trigger deployment component and further increase the overall anchoring strength. A locking ring is fixedly connected to the connecting part. The locking component includes an adjusting screw, an adjusting handwheel, a lifting guide rod, and a locking element. The adjusting handwheel is rotatably mounted on the top of the quick-installation reaction pile and is fixedly connected to one end of the adjusting screw. The other end of the adjusting screw sequentially passes through the top and partition of the quick-installation reaction pile and is rotatably connected to the inner bottom of the quick-installation reaction pile. The lifting guide rod is located on one side of the adjusting screw, with one end fixedly connected to the partition and the other end connected to the quick-installation component. The inner top of the reaction pile is fixedly connected, and the locking component is movably mounted in the upper cavity. The locking component includes a lifting collar, which is threadedly connected to an adjusting screw. One end of the lifting collar is provided with a sliding connection part, which is slidably connected to the lifting guide rod. The other end of the lifting collar is provided with a locking pressure plate, and a locking insert is fixedly provided at the bottom of the locking pressure plate. When the trigger deployment component is compressed and reaches the preset position, the locking pressure plate is located directly above the locking ring. The locking component can be driven to lower the locking pressure plate and press it against the upper surface of the locking ring, so that the locking insert is inserted into the locking ring, thereby locking the trigger deployment component.

[0011] Furthermore, a bottom anchor is provided in the lower chamber, which includes a lifting pressure plate and a bottom anchor plate. The bottom anchor plate is symmetrically arranged at the bottom of the lifting pressure plate and is movably inserted through the bottom of the quick-installation reaction pile. The bottom anchor plate is provided with a pointed tip. The middle part of the lifting pressure plate is threadedly connected to the adjusting screw. When the locking part is connected to the locking ring, the bottom anchor plate extends from the bottom of the quick-installation reaction pile and reaches the maximum unfolded state.

[0012] Furthermore, the horizontal load application component is positioned above the extrusion push plate. The horizontal load application component includes a hydraulic jack, a mounting plate, and a lifting seat. The output end of the hydraulic jack is connected to an extrusion section, and a pressure sensor is connected to the extrusion section. The extrusion section applies a horizontal load to the pile body under test. The hydraulic jack is bolted to the mounting plate, and the mounting plate is welded to one side of the lifting seat. The lifting seat has a sliding fit with a limit groove, which is opened on one end surface of the quick-installation reaction pile.

[0013] Furthermore, the top of the lifting platform is rotatably equipped with a hanging plate, and a lifting handle is also provided on the front side of the top of the lifting platform.

[0014] Furthermore, the quick-installation reaction pile has hoisting sections on both sides.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] 1. By working together with the hydraulic push device and the trigger deployment component, the reaction pile can be quickly self-anchored and installed. The hydraulic push rod drives the extrusion plate to push the reaction pile into one side of the foundation pit and compacts the soil layer under the reaction force. At the same time, the reaction force of the foundation pit wall triggers the transverse reaction pile to deploy and insert into the soil layers on both sides, forming a two-way anchorage. It does not require external hoisting or on-site pouring, which significantly shortens the testing preparation time and improves the efficiency of on-site operation.

[0017] 2. The locking component and the trigger deployment component are linked. When the reaction pile is pressed into place, the locking pressure plate and the locking ring can be inserted by adjusting the handwheel, which will simultaneously drive the bottom anchor plate to deploy, forming a mechanical lock. This prevents the device from rebounding or loosening during the testing process and improves the safety of the operation.

[0018] 3. The system adopts a linkage locking and bottom anchoring structure. When the trigger deployment component is pressed into place, the locking ring can be pressed down by adjusting the handwheel, which at the same time drives the bottom anchor plate to move down, realizing the synchronous completion of mechanical self-locking and vertical anchoring. This effectively resists the huge reaction force when horizontal loads are applied, ensuring the absolute stability of the support system during the testing process and guaranteeing accurate and reliable data.

[0019] 4. The horizontal load application component is height-adjustable and easy to move, which enhances the adaptability of the device to different working conditions. The lifting seat can adjust the force application height of the hydraulic jack along the limit slide. With the rotatable hanging plate and lifting handle, it is easy to quickly position and move the device. This allows the device to flexibly adapt to the piles under test with different exposure heights and positions, simplifying the adjustment process and expanding the application range of a single unit.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figures 1-10 As shown, this invention proposes a construction pile foundation testing device, including a quick-installation reaction pile 1, a horizontal load application component 34, a pile body 2 to be tested, and a displacement detection component 3. The pile body 2 to be tested is poured into a designated soil layer. The displacement detection component 3 is set on one side of the pile body 2 to be tested. The horizontal load application component 34 is detachably set at one end of the quick-installation reaction pile 1 to apply a lateral load to the pile body 2 to test its structural strength. The quick-installation reaction pile 1 is set on the other side of the pile body 2 to be tested. The quick-installation reaction pile 1 can be detachably set in a preset foundation pit. The quick-installation reaction pile 1 includes a hydraulic pushing device 5, a trigger deployment component 8, and a lateral reaction pile 16. Through the cooperation of the hydraulic pushing device 5 and the trigger deployment component 8, the quick-installation reaction pile 1 is quickly installed in the preset foundation pit while the deployment of the lateral reaction pile 16 is controlled to further increase the installation stability.

[0035] It should be noted that the displacement detection component 3 consists of a dial indicator and a reference support (such as...) Figure 1 As shown, the magnetic base of the dial indicator is attached to a stable reference support (which should be far away from the pile to be measured to avoid being affected by the pile's displacement). The probe of the dial indicator is placed against the preset measuring point on the pile. When the pile undergoes horizontal displacement, the probe moves with the pile, and the dial directly displays the displacement value. The dial indicator can achieve micron-level precision measurement.

[0036] In one embodiment of the present invention, the quick-installation reaction pile 1 is divided into an upper chamber 46 and a lower chamber 47 by a partition 21. A hydraulic pushing device 5 is disposed in the lower chamber 47. The hydraulic pushing device 5 is connected to a pressing push plate 6 by a hydraulic push rod 45. The pressing push plate 6 is telescopically disposed in a first groove 7. The first groove 7 is opened at the bottom of one end of the quick-installation reaction pile 1. The hydraulic pushing device 5 is used to push the quick-installation reaction pile 1 toward one end of a preset foundation pit to achieve rapid fixing.

[0037] In one embodiment of the present invention, the trigger deployment component 8 is extendable and disposed at the other end of the quick-installation reaction pile 1, for triggering the deployment of the transverse reaction pile 16 by relative compressive force. The trigger deployment component 8 includes a pressure-bearing push plate 9, a pressure-bearing push rod 10, a deployment connecting rod 13, and a pressure-bearing guide rod 14. The pressure-bearing push plate 9 is telescopically disposed within the second groove 44, which is formed on the surface of the other end of the quick-installation reaction pile 1. One end of the pressure-bearing push rod 10 is welded and fixed to the pressure-bearing push plate 9, and the other end of the push rod 10 movably passes through the second groove 44 and extends into the upper chamber 46. The other end of the pressure-bearing push rod 10 is fixedly connected to the second groove 44. A connecting part 11 is provided, and an unfolding connecting rod 13 is symmetrically arranged on both sides of the connecting part 11. One end of the unfolding connecting rod 13 is rotatably connected to the connecting part 11, and the other end is rotatably connected to the surface of the transverse reaction pile 16. Multiple pressure guide rods 14 are provided, and the multiple pressure guide rods 14 are distributed on both sides of the pressure push plate 9. One end of the pressure guide rod 14 is fixedly connected to the pressure push plate 9, and the other end movably passes through the second groove 44 and is provided with a limit structure. A return spring 15 is sleeved on the pressure guide rod 14. One end of the return spring 15 abuts against the pressure push plate 9, and the other end abuts against the surface of the second groove 44.

[0038] In one embodiment of the present invention, the transverse reaction pile 16 is telescopically disposed on both sides of the quick-installation reaction pile 1. The transverse reaction pile 16 is provided with a sliding connection part 17 on both sides. The sliding connection part 17 is slidably connected to a displacement guide rod 19. The displacement guide rod 19 is fixedly disposed on one side of the inner wall of the quick-installation reaction pile 1. The quick-installation reaction pile 1 is provided with an unfolding opening 20 on both sides. The transverse reaction pile 16 is telescopically disposed in the unfolding opening 20. The transverse reaction pile 16 is used to insert into the soil layer on both sides of the preset foundation pit and further compress it, thereby increasing the overall structural strength and counter-thrust force of the structure and preventing the quick-installation reaction pile 1 from being displaced due to the reaction force.

[0039] In one embodiment of the present invention, one end of the transverse reaction pile 16 is provided with an inclined surface 18, which is arranged in the direction of the reaction force so as to facilitate the insertion of the transverse reaction pile 16 into the soil layers on both sides.

[0040] In one embodiment of the present invention, a locking component 22 is provided inside the quick-installation reaction pile 1 to lock the trigger deployment component 8 and further increase the overall anchoring strength. A locking ring 12 is fixedly connected to the connecting part 11. The locking component 22 includes an adjusting screw 25, an adjusting handwheel 23, a lifting guide rod 48, and a locking element 24. The adjusting handwheel 23 is rotatably disposed on the top of the quick-installation reaction pile 1. The adjusting handwheel 23 is fixedly connected to one end of the adjusting screw 25. The other end of the adjusting screw 25 sequentially moves through the top of the quick-installation reaction pile 1 and the partition 21 and is rotatably connected to the inner bottom of the quick-installation reaction pile 1. The lifting guide rod 48 is disposed on one side of the adjusting screw 25. One end of the lifting guide rod 48 is fixedly connected to the partition 21 and its other end is connected to the quick-installation component 25. The inner top of the reaction pile 1 is fixedly connected, and the locking component 24 is slidably installed in the upper chamber 46. The locking component 24 includes a lifting collar 27, which is threadedly connected to the adjusting screw 25. One end of the lifting collar 27 is provided with a sliding sleeve part 28, which is slidably connected to the lifting guide rod 48. The other end of the lifting collar 27 is provided with a locking pressure plate 29. A locking insertion rod 30 is fixedly provided at the bottom of the locking pressure plate 29. When the trigger deployment component 8 is squeezed and reaches the preset position, the locking pressure plate 29 is located directly above the locking hanging ring 12. The locking pressure plate 29 can be lowered and pressed against the upper surface of the locking hanging ring 12 by driving the locking component 22, so that the locking insertion rod 30 is inserted into the locking hanging ring 12, thereby locking the trigger deployment component 8.

[0041] In one embodiment of the present invention, a bottom anchor 26 is provided in the lower chamber 47. The bottom anchor 26 includes a lifting pressure plate 31 and a bottom anchor plate 32. The bottom anchor plate 32 is symmetrically arranged at the bottom of the lifting pressure plate 31. The bottom anchor plate 32 is movably inserted through the bottom of the quick-installation reaction pile 1. The bottom anchor plate 32 is provided with a pointed tip 33. The middle part of the lifting pressure plate 31 is threadedly connected to the adjusting screw 25. When the locking member 24 is connected to the locking ring 12, the bottom anchor plate 32 extends out from the bottom of the quick-installation reaction pile 1 and reaches the maximum unfolded state.

[0042] In one embodiment of the present invention, a horizontal load application component 34 is disposed above the extrusion push plate 6. The horizontal load application component 34 includes a hydraulic jack 35, a mounting plate 38, and a lifting seat 39. The output end of the hydraulic jack 35 is connected to an extrusion part 37, and a pressure sensor is connected to the extrusion part 37. A horizontal load is applied to the pile body 2 under test through the extrusion part 37. The hydraulic jack 35 is bolted to the mounting plate 38. The mounting plate 38 is welded to one side of the lifting seat 39. The lifting seat 39 is slidably fitted with a limiting groove 42, which is opened on one end surface of the quick-installation reaction pile 1.

[0043] In one embodiment of the present invention, a hanging plate 41 is rotatably provided on the top of the lifting seat 39, and a lifting handle 40 is also provided on the front side of the top of the lifting seat 39.

[0044] In this embodiment, the hanging plate 41 is an L-shaped structural plate, and the height of the horizontal load application component 34 in the use state is achieved by rotating it to engage with the top of the quick-installation reaction pile 1.

[0045] In one embodiment of the present invention, the quick-installation reaction pile 1 has hoisting parts 43 on both sides.

[0046] Working principle: When using the construction pile foundation testing device of the present invention to test the horizontal load of the pile body under test, the components of the device are first transported to the pile foundation construction testing area. The relevant personnel first excavate a pre-set foundation pit on one side of the pile body 2 under test to ensure that the size of the foundation pit is compatible with the quick-installation reaction pile 1. At the same time, the displacement detection component 3 is fixedly set at the designated position on the other side of the pile body 2 under test, and the testing equipment is debugged to ensure that the data acquisition function is normal.

[0047] The front-to-back length of the pre-installed foundation pit needs to be greater than or equal to the front-to-back length of the quick-installed reaction pile 1 in its undeployed state, so that the extrusion push plate 6 in its undeployed state contacts the inner wall of one end of the pre-installed foundation pit, and the extrusion push plate 6 in its deployed state contacts the inner wall of the other end of the pre-installed foundation pit.

[0048] Subsequently, the quick-installation reaction pile 1 was hoisted and positioned: relevant personnel used hoisting equipment to smoothly place the quick-installation reaction pile 1 into the preset foundation pit, so that the side of the quick-installation reaction pile 1 facing the pile body 2 to be tested is parallel to the pile body 2 to be tested, and the placement posture of the quick-installation reaction pile 1 was adjusted to ensure that it is in a vertical and stable state, so as to provide basic support for subsequent load application.

[0049] It should be noted that the top of the pre-set foundation pit needs to be aligned with the top of the unfolding openings 20 on both sides of the quick-installation reaction pile 1 and the top of the pressure-bearing push plate 9, so that the transverse reaction pile 16 and the pressure-bearing push plate 9 can be exposed from the pre-set foundation pit when unfolded, so that the quick-installation reaction pile 1 can be directly hoisted and removed in its unfolded state after use.

[0050] Next, relevant personnel initially fixed the quick-installation reaction pile 1 to complete the foundation anchoring of the reaction pile. Among them, relevant personnel operated the hydraulic push device 5 through the controller, so that the hydraulic push device 5 drove the hydraulic push rod 45 to extend. The hydraulic push rod 45 drove the extrusion push plate 6 to slide out from the first groove 7. At this time, the extrusion push plate 6 was tightly attached to one side of the inner wall of the pre-set foundation pit and continued to apply pressure. The extrusion force was used to displace the quick-installation reaction pile 1 to the other side under the relative action force. At this time, the pressure-bearing push plate 9 contacted the inner wall of the other end of the foundation pit under the action of the reaction force and generated initial extrusion.

[0051] Furthermore, as the hydraulic pusher 5 continues to apply pressure, the quick-installation reaction pile 1 shifts to one side of the foundation pit. The compressive force on the pressure-bearing push plate 9 gradually increases and contracts into the quick-installation reaction pile 1, causing the pressure-bearing push rod 10 to move axially along the second groove 44. The pressure-bearing guide rod 14 slides synchronously, and the return spring 15 on its surface is compressed. The connecting part 11 at the end of the pressure-bearing push rod 10 moves accordingly, and the unfolding connecting rods 13 symmetrically connected on both sides deflect at an angle, pushing the transverse reaction pile 16 to slide along the displacement guide rod 19 to both sides of the quick-installation reaction pile 1. The transverse reaction pile 16 extends through the unfolding opening 20 and inserts into the soil layers on both sides of the foundation pit. The guiding effect of the inclined surface 18 makes the insertion process smoother, and a preliminary transverse anchoring system is formed.

[0052] When the transverse reaction pile 16 is fully inserted into the soil, i.e., when the pressure-bearing push plate 9 retracts into the second sliding groove 44, the locking ring 12 moves to the direct below the locking component 22. Personnel then rotate the adjusting handwheel 23 at the top of the quick-installation reaction pile 1, causing the adjusting screw 25 to rotate synchronously. Since the lifting collar 27 is threadedly connected to the adjusting screw 25 and forms a limiting engagement with the lifting guide rod 48 through the sliding sleeve 28, the lifting collar 27 drives the locking pressure plate 29 to descend vertically along the lifting guide rod 48. The locking rod 30 at the bottom of the locking pressure plate 29 is precisely inserted into the locking ring 12, stably locking the position of the trigger deployment component 8.

[0053] At the same time, while the locking component 22 is in motion, the lifting pressure plate 31 in the lower chamber 47 driven by the bottom of the adjusting screw 25 is lowered synchronously. The lifting pressure plate 31 drives the bottom anchor plate 32 to extend from the bottom of the quick-installation reaction pile 1. The tip 33 of the bottom anchor plate 32 is quickly inserted into the bottom soil layer of the foundation pit, forming a double anchoring structure of "lateral reaction pile + bottom anchor plate", ensuring that the quick-installation reaction pile 1 will not be displaced during subsequent load application.

[0054] Next, the relevant personnel can adjust and position the height of the horizontal load application component 34. Specifically, the personnel hold the lifting handle 40 on the top of the lifting seat 39, rotate the hanging plate 41 to separate it from the top of the quick-installation reaction pile 1, and push the lifting seat 39 downwards along the limiting groove 42 on the surface of the quick-installation reaction pile 1, causing the hydraulic jack 35 on the mounting plate 38 to rise and fall synchronously. Once the extrusion section 37 at the output end of the hydraulic jack 35 is aligned with the detection height of the pile body 2 under test, the mounting plate 38 is placed against the soil layer at the top of the foundation pit. Simultaneously, the pressure sensor connected to the extrusion section 37 is checked to ensure that load data can be collected in real time.

[0055] With the preparatory work completed, relevant personnel activated the power system of the hydraulic jack 35, slowly increasing the output load through the hydraulic control device. The extrusion section 37 applied a lateral load to the pile body 2 under test, and the pressure sensor provided real-time feedback of the load value, transmitting it to the data terminal. During the load application process, the displacement detection component 3 simultaneously collected the horizontal displacement data of the pile body 2 under test. The double anchoring structure of the quick-installation reaction pile 1, through the synergistic action of the lateral reaction pile 16 and the bottom anchor plate 32, stably withstood the reaction force generated by the hydraulic jack 35, ensuring the overall stability of the device during the testing process.

[0056] When the load reaches the detection standard value or the displacement of the pile body 2 reaches the preset threshold, stop increasing the load and keep the load stable. Record the final data of the displacement detection component 3 to complete one load level detection. If multiple load levels need to be detected, adjust the output load of the hydraulic jack 35 step by step according to the above procedure and collect data simultaneously.

[0057] After the test is completed, the hydraulic jack 35 is first controlled to retract the pressing part 37 to release the pressure on the pile body 2 under test. Then the hydraulic push device 5 is turned off, and the hydraulic push rod 45 drives the pressing push plate 6 to reset. At this time, the relevant personnel rotate the adjusting handwheel 23 in the opposite direction, which drives the adjusting screw 25 to reverse. The locking pressure plate 29 of the locking component 22 rises, causing the locking rod 30 to disengage from the locking ring 12. The bottom anchor plate 32 is simultaneously retracted into the quick-installation reaction pile 1. Then, the quick-installation reaction pile 1 can be lifted out as a whole and placed on the designated ground by the hoisting equipment through the hoisting parts 43 opened on both sides. During this process, the pressure-bearing push plate 9 separates from the inner wall of the foundation pit and rebounds under the elastic action of the return spring 15. The pressure-bearing push rod 10 and the unfolding connecting rod 13 drive the transverse reaction pile 16 to retract into the quick-installation reaction pile 1. The displacement detection component 3 is sorted and the detection data is exported, completing the entire pile foundation horizontal load detection process.

[0058] In summary, the present invention provides a construction pile foundation testing device that achieves rapid self-anchoring installation of reaction piles through the coordinated action of a hydraulic pusher and a trigger deployment component. A hydraulic pusher drives a pressing plate to push the reaction pile into one side of the foundation pit, compacting the soil layer there under the reaction force. Simultaneously, the reaction force of the foundation pit wall triggers the transverse reaction pile to deploy and insert into the soil layers on both sides, forming bidirectional anchoring. This eliminates the need for external hoisting or on-site pouring, significantly shortening the testing preparation time and improving on-site work efficiency. The locking component is linked to the trigger deployment component. Once the reaction pile is in place, the locking pressure plate can be engaged with the locking ring by adjusting the handwheel, simultaneously deploying the bottom anchor plate to form a mechanical lock. This prevents the device from rebounding or loosening during testing, improving operational safety. Employing a linkage locking and bottom anchoring structure, once the trigger deployment component is pressed into place, the locking mechanism can be adjusted via a handwheel to press down the locking ring, simultaneously causing the bottom anchor plate to extend downwards. This achieves simultaneous mechanical self-locking and vertical anchoring, effectively resisting the enormous reaction force under horizontal loads and ensuring the absolute stability of the support system during testing, guaranteeing accurate and reliable data. The horizontal load application component features height adjustability and easy mobility, enhancing the device's adaptability to various working conditions. The lifting seat allows adjustment of the hydraulic jack's application height along the limit slide, and the rotatable hanging plate and lifting handle facilitate rapid positioning and transport. This allows the device to flexibly adapt to piles at different exposure heights and positions, simplifying the adjustment process and expanding the application range of a single unit.
