Description

Technical Field

[0001] This invention relates to the field of foundation pile settlement monitoring technology, specifically to a high-strength reinforced foundation pile structure and a sensing monitoring device. Background Technology

[0002] In the field of building construction, foundation piles are key foundation components that bear the loads of the superstructure, and their stability and bearing capacity directly affect the safety of the overall structure. Traditional foundation piles mainly provide bearing capacity through the friction between the pile itself and the surrounding soil, as well as end resistance. However, in soft soil foundations, complex geological conditions, or when subjected to large horizontal loads (such as wind or seismic forces), traditional foundation piles may experience problems such as insufficient bearing capacity and excessive lateral displacement, affecting the safety of the project.

[0003] To improve the bearing capacity and stability of foundation piles, existing technologies often employ reinforcement methods such as enlarging the pile head, installing supports, or grouting the pile sides. However, these methods are often complex to construct, costly, and the reinforcement effect is difficult to control precisely and monitor in real time. For example, after pile side grouting reinforcement, it is difficult to guarantee the diffusion range of the grout and the uniformity of the reinforced body strength; while methods such as installing supports require high construction precision and have limited adaptability.

[0004] Furthermore, monitoring the health status of foundation piles, including settlement and tilting, during long-term use is equally crucial. Currently used monitoring methods (such as deploying external inclinometers and settlement observation points) are typically reactive or point-based, making it difficult to accurately and directly monitor foundation pile settlement. This may delay the optimal time for reinforcement and maintenance.

[0005] Therefore, there is an urgent need for a foundation pile device that integrates efficient reinforcement and real-time monitoring, which can conveniently form reliable reinforcement during the construction phase and continuously and sensitively detect settlement around the pile foundation during service, thereby improving the overall performance and safety of foundation pile engineering. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a high-strength foundation pile reinforcement structure and a sensing and monitoring device.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a high-strength reinforcement structure for foundation piles and a sensing and monitoring device, comprising a foundation pile part and a monitoring part. The foundation pile part includes a foundation pile body and a reinforcement seat arranged coaxially. The reinforcement seat is internally configured with a plurality of reinforcement components. The foundation pile body and the reinforcement seat are configured with an auxiliary rod. The auxiliary rod is connected to the reinforcement components. Rotating the auxiliary rod pushes the reinforcement components to extend outward through the reinforcement seat. The monitoring component includes a connecting rod and a monitoring sleeve. The connecting rod is connected to the bottom of the reinforcement base, and the monitoring sleeve is fitted over the outside of the connecting rod. The detection end of the connecting rod is equipped with a connecting spring. The inner wall of the monitoring sleeve is equipped with several vertically distributed resistance strips. The connecting spring contacts the resistance strips to form a monitoring circuit. When the connecting spring moves downward, the resistance of the monitoring circuit increases.

[0008] As an optimization, the lower end of the auxiliary rod is provided with a worm gear section, the reinforcement component includes a reinforcement rod and an adjusting rod, the end of the adjusting rod is provided with a connecting worm wheel, the connecting worm wheel is connected to the worm gear section, and the reinforcement rod is threadedly connected to the adjusting rod; The side wall of the reinforcing base has a limiting hole, and the reinforcing rod is slidably disposed in the limiting hole. By rotating the adjusting rod, the reinforcing rod is pushed to extend outward along the limiting hole.

[0009] As an optimization, the auxiliary rods on the inner side of the foundation pile body are evenly equipped with several stirring rods, which are used to stir the cement and remove air from the cement. The auxiliary rod is polygonal in shape.

[0010] As an optimization, a soft, retractable sleeve is connected between the monitoring sleeve and the bottom of the reinforcement base, and the retractable sleeve is coaxially arranged with the monitoring sleeve.

[0011] As an optimization, the lower end of the connecting rod extends into the middle of the monitoring sleeve, and a guide wheel is provided on the side of the lower end of the connecting rod away from the resistor strip, and the guide wheel contacts the inner wall of the monitoring sleeve; The guide wheel is equipped with a micro generator on its axle. When the connecting rod and the monitoring sleeve move relative to each other, the guide wheel drives the micro generator to operate and generate a micro current to power the monitoring circuit.

[0012] As an optimization, it also includes an operating lever, which has a connecting prism hole, and the auxiliary rod is a multi-faceted prism shape, and the auxiliary rod and the operating lever are detachably connected; The connecting rod is coaxially arranged with the foundation pile.

[0013] As an optimization, the lower end of the connecting rod is provided with a telescopic rod, and the connecting spring is connected to the movable end of the telescopic rod. The connecting spring is elliptical.

[0014] As an optimization, the connecting spring and the guide wheel are disposed opposite to each other on both sides of the connecting rod.

[0015] As an optimization, a connecting rod is also included, wherein the outer end of the stirring rod is provided with a first connecting groove with an outer opening, and the bottom inner side of the reinforcing base is provided with a second connecting groove, and the first connecting groove and the second connecting groove are arranged vertically opposite each other. After the device is installed, the connecting rod is passed through the first connecting groove from top to bottom and then inserted into the second connecting groove. The upper end of the connecting rod is then welded and fixed to the main body of the foundation pile.

[0016] The beneficial effects of this plan are as follows: By setting up a coaxial reinforcing base and internal reinforcing components, and using an auxiliary rod drive (such as a worm gear drive), the extension of the reinforcing rod from the side wall of the reinforcing base can be precisely controlled. This process can be carried out after the pile is poured or at a specific time, allowing the reinforcing rod to insert into the surrounding soil, forming an anchoring effect similar to "tree roots," which greatly improves the lateral bearing capacity and pull-out resistance of the pile. The reinforcement depth and range can be adjusted by the number of rotations of the auxiliary rod. The operation is simple, and the reinforcement effect is uniform and reliable. After installation, the connecting rod is inserted between the mixing rod and the main body of the foundation pile, so that the auxiliary rod and the main body of the foundation pile form a firmly connected whole, further strengthening the strength of the main body of the foundation pile.

[0017] The monitoring section forms a monitoring circuit by connecting a spring at the lower end of the connecting rod to vertically distributed resistance strips on the inner wall of the monitoring sleeve. When settlement or tilting of the pile foundation causes relative displacement between the connecting rod and the monitoring sleeve, the spring slides along the resistance strips, changing the resistance value of the circuit. This resistance change can be detected by an external circuit and converted into a displacement, thus achieving real-time, continuous, and electrically signal-based monitoring of the vertical settlement or tilting deformation of the pile foundation with high sensitivity.

[0018] The reinforcement structure and monitoring device are integrated into a single design, both surrounding the foundation pile body and the reinforcement base. Core components such as the connecting rods for the reinforcement and monitoring parts are built-in, occupying no extra space and facilitating simultaneous construction and installation with the pile body. The auxiliary rod simultaneously functions as a driver for reinforcement and a mixer for cement pouring (via a mixing rod), offering multiple uses and improving construction efficiency.

[0019] In the preferred embodiment, a guide wheel and a micro-generator with its axle are mounted on the connecting rod. When the connecting rod and the monitoring sleeve move relative to each other due to pile deformation, the guide wheel rolls and drives the micro-generator to generate a micro-current, which can power the monitoring circuit or other low-power sensing elements, enabling signal transmission. This reduces dependence on external power sources and is particularly suitable for long-term, field, or passive environment monitoring, enhancing the durability of the device.

[0032] like Figures 1 to 8 As shown, a high-strength reinforcement structure for foundation piles and a sensing and monitoring device include a foundation pile part and a monitoring part. The foundation pile part includes a foundation pile body 1 and a reinforcement seat 2 arranged coaxially. The reinforcement seat 2 is equipped with a plurality of reinforcement components. The foundation pile body 1 and the reinforcement seat 2 are equipped with an auxiliary rod 3. The auxiliary rod 3 is connected to the reinforcement components. Rotating the auxiliary rod 3 pushes the reinforcement components to extend outward through the reinforcement seat 2. The monitoring part includes a connecting rod 4 and a monitoring sleeve 5. The connecting rod 4 is connected to the bottom of the reinforcing base 2, and the monitoring sleeve 5 is sleeved on the outside of the connecting rod 4. The detection end of the connecting rod 4 is equipped with a connecting spring 6, and the inner wall of the monitoring sleeve 5 is equipped with several vertically distributed resistance strips 7. The connecting spring 6 contacts the resistance strips 7 to form a monitoring circuit. When the connecting spring 6 moves downward, the resistance of the monitoring circuit increases.

[0033] The foundation pile body 1 and the reinforcing base 2 are separate structures, but they are installed in contact. The outer diameter of the reinforcing base 2 is not less than the outer diameter of the foundation pile, and the top of the reinforcing base 2 is rotatably sealed to the auxiliary rod 3. When concrete is poured into the foundation pile body 1, it does not affect the operation of the internal reinforcing components of the reinforcing base 2.

[0034] The connecting rod 4 is welded to the bottom of the reinforcing base 2 or integrally formed with the bottom of the reinforcing base 2. The monitoring sleeve 5 is coaxially arranged with the connecting rod 4. The connecting rod 4 is used to monitor the settlement of the foundation pile. When the foundation pile settles, the reinforcing base 2 pushes the connecting rod 4 downward, causing relative displacement between the connecting spring 6 and the resistor strip 7, which changes the resistance value of the monitoring circuit.

[0035] like Figure 4 As shown, the lower end of the auxiliary rod 3 is provided with a worm section, the reinforcement component includes a reinforcement rod 8 and an adjusting rod 9, the end of the adjusting rod 9 is provided with a connecting worm wheel 10, the connecting worm wheel 10 is connected to the worm section, and the reinforcement rod 8 is threadedly connected to the adjusting rod 9; The side wall of the reinforcing base 2 has a limiting hole, and the reinforcing rod 8 is slidably disposed in the limiting hole. By rotating the adjusting rod 9, the reinforcing rod 8 is pushed to extend outward along the limiting hole.

[0036] The reinforcing rod 8 is a hollow prism-shaped structure. The inner cavity of the reinforcing rod 8 is provided with connecting threads, so that the reinforcing rod 8 is threadedly connected to the adjusting rod 9. The outer end of the reinforcing rod 8 is a pointed tip.

[0037] like Figure 3 As shown, the auxiliary rods 3 inside the foundation pile body 1 are evenly equipped with a number of stirring rods 11, which are used to stir the cement and remove air from the cement. The auxiliary rod 3 is a polygonal prism.

[0038] The stirring rod 11 is used to agitate and beat the poured cement to reduce the cavities in the pouring cavity.

[0039] like Figure 3 As shown, a soft, retractable sleeve 12 is connected between the monitoring sleeve 5 and the bottom of the reinforcing base 2, and the retractable sleeve 12 is coaxially arranged with the monitoring sleeve 5.

[0040] The telescopic sleeve 12 can be made of soft plastic, rubber or silicone. The upper end of the telescopic sleeve 12 is sealed to the bottom surface of the reinforcing base 2 to prevent external soil from entering the interior of the monitoring sleeve 5.

[0041] like Figure 3 and Figure 5As shown, the lower end of the connecting rod 4 extends into the middle of the monitoring sleeve 5, and a guide wheel 13 is arranged on the side of the lower end of the connecting rod 4 away from the resistor strip 7. The guide wheel 13 is in contact with the inner wall of the monitoring sleeve 5. The guide wheel 13 is equipped with a micro generator on its axle. When the connecting rod 4 and the monitoring sleeve 5 move relative to each other, the guide wheel 13 drives the micro generator to operate and generate a micro current to power the monitoring circuit.

[0042] Multiple resistor bars 7 are arranged side by side to form a variable resistor. The variable resistor and the connecting spring 6 form a sliding variable resistance structure. When the relative position of the connecting rod 4 and the variable resistor changes, the resistance value of the monitoring circuit changes.

[0043] The guide wheel 13 guides the movement of the connecting rod 4. The current generated by the micro generator is connected to the monitoring circuit to provide instantaneous power for monitoring the resistance of the monitoring circuit. The monitoring circuit is also equipped with a conventional power supply.

[0044] like Figure 3 and Figure 8 As shown, it also includes an operating lever 14, which has a connecting prism hole. The auxiliary rod 3 is a multi-faceted prism, and the auxiliary rod 3 and the operating lever 14 are detachably connected. The connecting rod 4 is coaxially arranged with the foundation pile.

[0045] The operating lever 14 is used to connect to the auxiliary lever 3. The operating lever 14 is assembled through an external drive device to drive the auxiliary lever 3 to rotate.

[0046] like Figure 5 As shown, the lower end of the connecting rod 4 is equipped with a telescopic rod 15, and the connecting spring 6 is connected to the movable end of the telescopic rod 15. The connecting spring 6 is elliptical.

[0047] The connecting spring 6 and the guide wheel 13 are disposed opposite to each other on both sides of the connecting rod 4.

[0048] The long diameter of the connecting spring 6 is vertically oriented to allow for appropriate deformation. The telescopic rod 15 is designed to allow the connecting spring 6 to press against the resistor bar 7.

[0049] like Figures 9-11 As shown, it also includes a connecting rod 16. The outer end of the stirring rod 11 is provided with a first connecting groove 17 with an outer opening, and the bottom inner side of the reinforcing base 2 is provided with a second connecting groove 18. The first connecting groove 17 and the second connecting groove 18 are arranged vertically opposite each other. After the device is installed, the connecting rod 16 is passed through the first connecting groove 17 from top to bottom and then inserted into the second connecting groove 18. The upper end of the connecting rod 16 is welded and fixed between it and the foundation pile body 1.

[0050] The connecting rod 16 passes through all the first connecting slots 17 in the vertical direction from top to bottom. Finally, the lower end of the connecting rod 16 is inserted into the second connecting slot 18, so that the auxiliary rod 3 can no longer rotate. The outer side of the connecting rod 16 is pressed tightly against the inner wall of the foundation pile body 1. A rigid and fixed reinforcing structure is formed between the foundation pile body 1, the auxiliary rod 3 and the reinforcing seat 2, providing stable support for the concrete inside the foundation pile body 1.

[0051] The connecting rod 16 can be made of Q355B steel, and the welding material is matched with E50 series welding rods to form a weld point on the inner side of the top of the foundation pile body 1.

[0052] How to use: When the device is used, firstly, a hole is drilled to the design depth at the predetermined pile position. Then, a monitoring hole is opened at the design depth. The monitoring sleeve 5 is installed into the monitoring hole, and the reinforcing seat 2 is placed on top of the monitoring hole. The diameter of the steel pipe pile installation hole is larger than the diameter of the monitoring hole. The main body 1 of the foundation pile is hoisted into the installation hole, so that the main body 1 of the foundation pile and the auxiliary rod 3 are coaxially set. Concrete is poured into the interior of the main body 1 of the foundation pile, while the auxiliary rod 3 is slowly swung and the concrete is stirred by the mixing rod 11 to avoid the filling cavity and improve the compactness of the concrete. Continue to rotate the auxiliary rod 3, which drives the connecting worm gear 10 to rotate, pushing the reinforcing rod 8 to extend outward and forming a root-like anchor on the outside of the reinforcing seat 2.

[0053] The connecting rod 16 is inserted from top to bottom into the first connecting groove 17 and the second connecting groove 18. The connecting rod 16 connects the auxiliary rod 3, the stirring rod 11 and the foundation pile body 1 into a whole, forming a high-strength support frame, which enhances the rigidity and bending resistance of the foundation pile body 1 itself.

[0054] Once the concrete reaches its designed strength, the complete foundation pile body 1 will be formed.

[0055] Connect the resistor strip 7 leads and the micro-generator output lines inside the monitoring sleeve 5 to the ground-based data acquisition box. The acquisition box contains a bridge circuit, an analog-to-digital converter, a microprocessor, and a power management module. Before the foundation piles are put into use, record the initial resistance value of the monitoring circuit as the reference zero point for settlement / displacement.

[0056] During the service life of the foundation pile, any relative displacement (settlement or tilt) between the main body of the foundation pile 1 and the surrounding soil caused by load, soil creep, etc., will cause the connecting rod 4 and the monitoring sleeve 5 to move relative to each other.

[0057] The change in position of the connecting spring 6 on the resistor bar 7 causes a change in the resistance value of the monitoring circuit. The data acquisition system measures this resistance change in real time and converts it into a precise displacement.

[0058] As the connecting piece moves relative to the monitoring sleeve 5, it drives the guide wheel 13 to roll, which in turn drives the micro generator to generate electricity and replenish the power to the monitoring circuit.

[0059] The collected displacement data can be transmitted to the monitoring center via wired or wireless means. By analyzing the displacement-time curve, the health status of the pile foundation can be assessed, and an automatic warning can be issued when the displacement exceeds the safety threshold, providing a scientific basis for timely maintenance measures.

The patent protection scope of the present invention includes, but is not limited to, the product form and style of the above-described specific embodiments.
