Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a protective tool for adjacent buildings used in the construction of water-rich pile foundations. Background Technology

[0002] When constructing pile foundations in water-rich strata such as soft soil, sand, or high-water areas, groundwater can easily flow into the foundations of adjacent buildings during excavation, causing safety hazards such as foundation settlement and wall cracking. Traditional protective measures often use steel sheet piles or concrete retaining walls, which cannot monitor water seepage in real time and can only assess risks through subsequent building deformation, delaying timely intervention. Furthermore, existing detection equipment needs to be deployed independently, resulting in poor coordination with the protective structure and increasing construction difficulty.

[0003] Therefore, there is an urgent need for a tooling system that integrates protection and real-time detection functions, which can dynamically sense the risk of seepage while blocking water flow and respond quickly. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a protective tooling for adjacent buildings used in the construction of water-rich pile foundations.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a protective fixture for adjacent buildings in the construction of water-rich pile foundations, including a protective pile and a detection component. The detection component is sleeved on the outside of the protective pile. The detection component includes a detection ring and a detection plate vertically connected to the outside of the detection ring. The detection plate has a water inlet channel. Sealing membranes are detachably installed at both ends of the water inlet channel. A sealing baffle is movably installed in the middle of the water inlet channel. A telescopic rod is configured between the sealing baffle and the inner wall of the detection plate. After the water flows into the water inlet channel, it pushes the sealing baffle to move, so that the middle of the water inlet channel is unobstructed.

[0006] As an optimization, the upper part of the detection plate is flush with the upper surface of the detection ring, and the bottom of the detection plate is provided with a guide blade. The bottom of the guide blade gradually shortens upward from the outer end of the detection plate towards the detection ring, so that a buffer angle is formed between the bottom of the detection plate and the protective pile.

[0007] As an optimization, the water inlet channel is arranged perpendicular to the detection plate, and filter screens are provided at both ends of the water inlet channel, with the sealing membrane disposed on the outside of the filter screens; The detection ring has an internal cavity, and a take-up roller is arranged inside the cavity. One end of the sealing film is connected to the take-up roller.

[0008] As an optimization, the winding roller is equipped with a spring shaft at its axis, and the winding roller has a tendency to wind up the sealing film; A locking rod is rotatably connected to the outside of the receiving cavity. The locking rod is detachably connected to the take-up roller and is used to lock the position of the take-up roller.

[0009] As an optimization, a spring shaft is connected between the locking rod and the end away from the winding roller and the detection ring. The winding roller is equipped with a locking block, and the locking rod is positioned and engaged with the locking block. The locking rod is located on the side of the locking block adjacent to the protective pile, and an auxiliary magnetic block is provided on the side of the locking rod adjacent to the protective pile. In use, the magnetic block is inserted into the protective pile, and the magnetic block is magnetically attracted to the auxiliary magnetic block, causing the locking rod to rotate towards the protective pile and separate from the locking block, so that the winding roller can wind up the sealing film.

[0010] As an optimization, a detection port is provided inside the water inlet channel, and the sealing baffle is movably sealed inside the detection port. The water flow pushes the sealing baffle to move, causing the sealing baffle to separate from the detection port, and the water flow passes through the detection port.

[0011] As an optimization, the detection plate is placed between the construction area and the adjacent building, with its length direction perpendicular to the line connecting the construction area and the adjacent building.

[0012] As an optimization, the telescopic pole is internally equipped with a distance sensor, which is used to detect the amount of extension and retraction of the telescopic pole.

[0013] The beneficial effects of this plan are as follows: This application integrates active monitoring and protection. The detection plate uses a linkage structure between the water inlet channel and the sealing baffle. When water seeps in, it automatically triggers the displacement of the sealing baffle. The distance sensor on the telescopic rod provides real-time feedback on the seepage volume, enabling early warning of risks. The detection plate is arranged vertically to the construction area and the building, specifically blocking the seepage path and providing precise protection. The guide blade and buffer angle design reduce soil resistance, ensuring that the protective pile is driven vertically, while also dispersing lateral pressure. The sealing film is easily removed after installation thanks to the design of the take-up roller and spring shaft, making operation convenient. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

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, and therefore should not be construed as a limitation of this invention.

[0021] like Figures 1-4 As shown, a protective device for adjacent buildings used in the construction of water-rich pile foundations includes a protective pile 1 and a detection component. The detection component is sleeved on the outside of the protective pile 1. The detection component includes a detection ring 2 and a detection plate 3 vertically connected to the outside of the detection ring 2. The detection plate 3 has a water inlet channel 4. Sealing membranes 5 are detachably installed at both ends of the water inlet channel 4. A sealing baffle 6 is movably installed in the middle of the water inlet channel 4. A telescopic rod 7 is arranged between the sealing baffle 6 and the inner wall of the detection plate 3. After the water flows into the water inlet channel 4, it pushes the sealing baffle 6 to move, so that the middle of the water inlet channel 4 is unobstructed.

[0022] The protective pile 1 is made of high-strength steel pipe with galvanized or anti-corrosion coating to improve durability. The bottom of the pile can be equipped with a conical pile tip to facilitate driving into water-rich soft soil layers. The pile body is hollow inside to facilitate the installation of magnetic control operating mechanism.

[0023] The detection ring 2 is directly fitted onto the outside of the protective pile 1, and multiple rings can be evenly set along the height direction of the protective pile 1.

[0024] Pre-drilling is required during installation. The diameter of the pre-drilled holes is slightly larger than the diameter of the protective pile 1, but smaller than the diameter of the detection component. The detection plate 3 is elongated and arranged perpendicular to the line connecting the construction area and the adjacent building.

[0025] like Figure 2 As shown, the upper part of the detection plate 3 is flush with the upper surface of the detection ring 2, and the bottom of the detection plate 3 is provided with a guide blade 8. The bottom of the guide blade 8 gradually shortens upward from the outer end of the detection plate 3 toward the detection ring 2, so that the bottom of the detection plate 3 and the protective pile 1 form a buffer angle.

[0026] The guide blade 8 and the buffer angle design reduce soil resistance, ensure that the protective pile 1 is driven in vertically, and at the same time disperse lateral pressure.

[0027] like Figure 4 As shown, the water inlet channel 4 is arranged perpendicular to the detection plate 3, and filter screens 9 are provided at both ends of the water inlet channel 4. The sealing membrane 5 is arranged on the outside of the filter screens 9. The detection ring 2 has a receiving cavity 10 inside, and a take-up roller 11 is arranged inside the receiving cavity 10. One end of the sealing film 5 is connected to the take-up roller 11.

[0028] The detection ring 2 has a built-in receiving cavity 10 that integrates a winding mechanism, resulting in a compact overall structure that avoids damage to external components.

[0029] A connecting layer is provided between the receiving cavity 10 and the water inlet channel 4, and the sealing membrane 5 is drawn into the receiving cavity 10 through the connecting layer.

[0030] like Figure 4 As shown, the winding roller 11 has a spring shaft arranged on its axis, and the winding roller 11 has a tendency to wind up the sealing film 5. A locking rod 12 is rotatably connected to the outside of the receiving cavity 10. The locking rod 12 is detachably connected to the take-up roller 11 and is used to lock the position of the take-up roller 11.

[0031] The sealing membrane 5 is made of PVC or EPDM rubber, with a thickness of 1-2mm and a water pressure resistance of ≥0.2MPa.

[0032] The locking rod 12 has a tendency to rotate in the direction of the protective pile 1. After the locking rod 12 separates from the winding roller 11, the winding roller 11 quickly retracts the sealing film 5.

[0033] like Figure 4As shown, a spring shaft is connected between the locking rod 12 and the end away from the winding roller 11 and the detection ring 2. The winding roller 11 is equipped with a locking block. The locking rod 12 is positioned and locked with the locking block. The locking rod 12 is located on the side of the locking block adjacent to the protective pile 1. An auxiliary magnetic block 13 is provided on the side of the locking rod 12 adjacent to the protective pile 1. In use, the magnetic block is inserted into the protective pile 1, and the magnetic block is magnetically attracted to the auxiliary magnetic block 13, causing the locking rod 12 to rotate in the direction of the protective pile 1 and separate from the locking block, so that the winding roller 11 can wind up the sealing film 5.

[0034] The operating magnetic block extends downward into the protective pile 1 via a steel wire rope or rod, magnetically attracting the auxiliary magnetic block 13 on the inside of the detection ring 2, thus separating the locking rod 12 from the locking block. The auxiliary magnetic block 13 can also be used for settlement monitoring.

[0035] like Figure 4 As shown, the water inlet channel 4 has a detection port 14 inside, and the sealing baffle 6 is movably sealed inside the detection port 14. The water flow pushes the sealing baffle 6 to move, so that the sealing baffle 6 is separated from the detection port 14, and the water flows through the detection port 14.

[0036] A vertical detection plate 3 is installed in the water inlet channel 4, with filter screens 9 installed at both ends to prevent silt blockage. The sealing baffle 6 is made of rubber or polyurethane, which has good sealing performance and wear resistance. The detection port 14 is located in the middle of the water inlet channel 4. The detection is triggered when the water flow pushes the sealing baffle 6.

[0037] like Figure 1 As shown, the detection plate 3 is set between the construction area and the adjacent building, with its length direction perpendicular to the line connecting the construction area and the adjacent building.

[0038] The telescopic rod 7 is equipped with a distance sensor inside, which is used to detect the extension and retraction of the telescopic rod 7.

[0039] By detecting the water flow through the detection plates 3 at different locations, real-time data feedback on the water flow is obtained, reducing blind grouting or reinforcement and saving project costs.

[0040] Based on geological survey data, determine the driving depth and spacing of protective piles 1, usually 1-2m. Check the detection components, such as detection ring 2, detection plate 3, and sealing membrane 5, to ensure they are intact and that the filter screen 9 is not clogged. The protective pile 1 is driven vertically into the water-rich stratum using a vibratory hammer or static pile driver until the design elevation is reached; the guide blade 8 and the buffer angle design reduce soil resistance and ensure that the verticality deviation of the pile body is ≤1%; Set the detection ring 2 outside the protective pile 1, and adjust the direction of the detection plate 3 so that it is perpendicular to the line connecting the construction area and the adjacent building; By manipulating the magnetic block to magnetically attract the auxiliary magnetic block 13, the sealing membrane 5 is pulled outward, thus opening the water inlet channel 4. When water seeps in, it pushes the sealing baffle 6 to move, triggering the distance sensor of the telescopic rod 7. The monitoring system displays the seepage volume in real time. If it exceeds the threshold (such as 10mm displacement), grouting or reinforcement measures are immediately initiated.
