Technical Field
[0001] This invention relates to the field of building engineering technology, and in particular to a prestressed concrete pipe pile static pressure pile. Background Technology
[0002] Static pressure piling is a pile driving process that uses the piling mechanism of a static pile driver, with the piling machine's own weight and counterweights on the frame providing the reaction force, to press precast piles into the soil. It completely avoids the vibration, noise, and pollution caused by hammer piling, and does not damage the pile. During construction, the pile body is less prone to cracks and other defects. Static pressure piling offers high construction precision, and the verticality and positional deviation of the pile body are easier to control, effectively ensuring the bearing capacity and stability of the pile foundation. However, it has the following drawbacks:
[0003] When the required length of static pressure piles is long, the inconvenience of connecting two static pressure piles compromises the ease of connection, reliability, and coaxiality, affecting the normal use of the static pressure piles. Therefore, there is a need to provide a prestressed concrete pipe pile static pressure pile that can solve the problem of inconvenient connection of static pressure piles in the existing technology. Summary of the Invention

[0010] The slot has side grooves on both sides; the insert plate has a movable groove, and the insert plate has side grooves on both sides near the top plate, so that when the insert plate is inserted into the slot, a pair of side grooves are aligned with a pair of side grooves; a pair of movable plates are movably disposed in the movable groove, one end of the pair of movable plates is connected by a spring, and the other end of the pair of movable plates is connected to a locking plate, and the pair of locking plates can pass through the side grooves and be inserted into the side grooves.
[0011] The end of the movable groove away from the top plate passes through the outer side of the arc plate via the outer groove. A pair of push plates are respectively connected to one end of a pair of movable plates, and the pair of push plates are movably arranged in the outer groove.
[0012] The side groove is equipped with a push plate. After the clamping plate is inserted into the side groove, it abuts against the push plate.

[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1. This invention, by comprising a bottom plate, a top plate, and a combined fixing component, utilizes the positioning groove of the bottom plate and the positioning block of the top plate to achieve coaxial positioning of two adjacent static pressure piles, ensuring convenient connection and coaxiality of the static pressure piles.

[0016] 2. Because the present invention includes a bottom plate, a top plate, and a combined fixing component, the installation of insert plates and slots and their matching insertion, as well as the installation of transverse locking rods and side slots and their matching insertion, facilitates the quick and accurate connection of the arc plate to the top plate. At the same time, the installation of side through slots and transverse locking rods and their matching insertion facilitates the quick and accurate connection of the arc plate to the bottom plate, thereby ensuring the reliability of the connection between the bottom plate and the top plate, and thus ensuring the reliability of the connection between the two static pressure piles.

This invention, by comprising a bottom plate, a top plate, and a combined fixing component, uses a push plate, a movable plate, and a spring to control a pair of locking plates to move relatively far apart or relatively close together. This allows the pair of locking plates to be inserted into the side groove of the top plate and push the push plate to move synchronously. The hinged connecting rod then uses a longitudinal locking rod to pass through the top surface of the top plate along the rod groove and insert into the bottom through groove. The longitudinal locking rod is finally inserted into the bottom locking groove, effectively locking and connecting the positioning block, the bottom plate, and the transverse locking rod. This ensures the reliability of the connection between the bottom plate, the top plate, and the combined fixing component, thereby ensuring the reliability of the connection between adjacent static pressure piles.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] Please see the appendix Figure 1 To be continued Figure 3 A prestressed concrete pipe pile static pressure pile includes a static pressure pile 1, a bottom end plate 2, a top end plate 3, and a combined fixing member 4; the bottom end plate 2 is disposed at the bottom end of the static pressure pile 1, and the top end plate 3 is installed at the top end of the static pressure pile 1. The bottom end plate 2 and the top end plate 3 are matched and inserted to make two adjacent static pressure piles 1 coaxially connected; the bottom end plate 2 and the top end plate 3 are connected by the combined fixing member 4 to make two adjacent static pressure piles 1 coaxially fixedly connected.
[0029] The bottom plate 2 and the top plate 3 are used for quick and accurate coaxial positioning of two adjacent static pressure piles 1, facilitating the coaxial connection and assembly of the static pressure piles 1. The assembly fastener 4 is used to connect and fix the bottom plate 2 and the top plate 3, allowing the two adjacent static pressure piles 1 to be connected and assembled into a whole, facilitating the extension of the static pressure piles 1, and ensuring the convenience, reliability, and coaxiality of the connection to meet construction requirements.
[0030] Please see the appendix Figure 4 To be continued Figure 6 The bottom plate 2 includes a bottom plate 201, the top surface of which is coaxially mounted on the bottom end of the static pressure pile 1, and a plurality of positioning grooves 203 are formed at intervals on the bottom of the bottom plate 201; the top plate 3 includes a top plate 301, the bottom surface of which is coaxially mounted on the top end of the static pressure pile 1, and a plurality of positioning blocks 303 are formed at intervals on the top surface of the top plate 301; when two adjacent static pressure piles 1 are connected, the plurality of positioning blocks 303 are respectively inserted into the plurality of positioning grooves 203.
[0031] Preferably, four positioning slots 203 are equally spaced, and correspondingly, four positioning blocks 203 are also equally spaced. This allows for quick and accurate positioning of two adjacent static pressure piles 1 by inserting the four positioning blocks 203 into the four positioning slots 203, ensuring the coaxiality and convenience of the connection of the static pressure piles 1.
[0032] The number of positioning blocks 203 and positioning slots 203 can be adjusted according to actual needs. The number of positioning blocks 203 and positioning slots 203 should be the same and at least two should be set.
[0033] Preferably, both the top plate 301 and the bottom plate 201 adopt a disc-shaped structure with the same diameter as the static pressure pile 1, which facilitates the installation of the top plate 301 and the bottom plate 201 on the top and bottom of the static pressure pile 1.
[0034] Please see the appendix Figure 3 and attached Figure 4 The bottom plate 201 has a lower annular groove 202 formed circumferentially at its lower edge, and the top plate 301 has an upper annular groove 302 formed circumferentially at its upper edge. When the bottom plate 2 and the top plate 3 are inserted, the lower annular groove 202 and the upper annular groove 302 form an annular groove. The combined fixing member 4 is embedded in the annular groove and movably connects the bottom plate 2 and the top plate 3.
[0035] Preferably, the lower annular groove 202 and the upper annular groove 302 are at the same height, and the height and depth of the annular groove are consistent with the height and thickness of the combined fastener 4, respectively, thereby ensuring the vertical stress stability of the static pressure pile 1. By matching and embedding the combined fastener 4 in the annular groove, it is easy to quickly and reliably connect the bottom plate 2 and the top plate 3 through the combined fastener 4.
[0036] Please see the appendix Figure 4 To be continued Figure 7 The combined fixing component 4 includes an arc plate 401, a transverse locking rod 402, and an insert plate 404; a pair of semi-circular arc plates 401 are spliced to form a circular structure and can be matched and locked into the annular groove; the insert plate 404 and the transverse locking rod 402 are respectively disposed on the inner wall of the arc plate 401, and the pair of transverse locking rods 402 are located on both sides of the insert plate 404; a slot 305 is formed in the upper annular groove 302, and the insert plate 404 is matched and inserted into the slot 305; positioning block 30 A side groove 304 is formed inside the base plate 201. The axial direction of the side groove 304 is perpendicular to the axial direction of the positioning block 303. A side through groove 204 is formed inside the base plate 201. The two ends of the side through groove 204 are perpendicularly connected to the positioning groove 203 and the lower ring groove 202, respectively. When the positioning block 303 is inserted into the positioning groove 203, the side groove 304 and the side through groove 204 are aligned, so that the transverse locking rod 402 can be matched and inserted into the side groove 304 and the side through groove 204.
[0037] The arrangement and matching of the insert plate 404 and slot 305, and the arrangement and matching of the transverse locking rod 402 and side locking groove 304, facilitate the quick and accurate connection of the arc plate 401 to the top plate 301. Similarly, the arrangement and matching of the side through groove 204 and transverse locking rod 402 facilitate the quick and accurate connection of the arc plate 401 to the bottom plate 201.
[0038] The side through slot 204 and the horizontal locking rod 402 are set in a horizontal direction, as are the insertion plate 404 and the slot 305. The horizontal locking rod 402 and the side locking slot 304 are also horizontal. After insertion, they can be used to restrict the relative vertical movement between the arc plate 401, the bottom plate 201 and the top plate 301, thereby improving the connection reliability.
[0039] Please see the appendix Figure 6 To be continued Figure 8 The slot 305 has side grooves 306 on both sides; the insert plate 404 has a movable groove 405, and the insert plate 404 has side grooves 406 on both sides near the top plate 3, so that when the insert plate 404 is inserted into the slot 305, the pair of side grooves 406 are aligned with the pair of side grooves 306 respectively; the pair of movable plates 407 are movably disposed in the movable groove 405, one end of the pair of movable plates 407 is connected by a spring 409, and the other end of the pair of movable plates 407 is connected to a locking plate 408 respectively, and the pair of locking plates 408 can pass through the side grooves 406 and be inserted into the side grooves 306.
[0040] When a pair of movable plates 407 approach each other in the movable slot 405, they can drive a pair of locking plates 408 to approach synchronously, thereby causing the pair of locking plates 408 to retract into the movable slot 405, avoiding interference with the insertion of the insert plate 404 and the slot 305; at this time, the spring 409 contracts and stores force.
[0041] When the pair of movable plates 407 move away from each other within the movable slot 405 due to the elastic force of the spring 409, they can drive the pair of locking plates 408 to move away synchronously, and allow the pair of locking plates 408 to pass through the side slot 406 and then insert into the side slot 306. Preferably, the movement direction of the pair of locking plates 408 is radially perpendicular to the arc plate 401, thereby playing a radial limiting role and locking the insert plate 404 within the slot 305.
[0042] Please see the appendix Figure 8 The end of the movable groove 405 away from the top plate 3 passes through the outer side of the arc plate 401 through the outer groove 410. A pair of push plates 411 are respectively connected to one end of a pair of movable plates 407. The pair of push plates 411 are movably arranged in the outer groove 410.
[0043] The through-hole design of the outer groove 410 facilitates manual control of the movement of a pair of push plates 411 by construction personnel, thereby driving a pair of movable plates 407 to move away from or towards each other. The dimensions of the outer groove 410 can be adaptively adjusted according to actual needs, ensuring sufficient space for manual operation of the push plates 411.
[0044] Please see the appendix Figure 6 The side groove 306 is provided with a push plate 308. After the clamping plate 408 is inserted into the side groove 306, it abuts against the push plate 308. A rod groove 307 is formed on the side of the side groove 306 away from the slot 305. The vertically arranged rod groove 307 extends upward through the top surface of the top plate 301. The longitudinal clamping rod 309 is movably clamped in the rod groove 307. A connecting rod 310 is movably provided in the side groove 306. The two ends of the connecting rod 310 are respectively hinged to the push plate 308 and the longitudinal clamping rod 309. A bottom through groove 205 is formed in the bottom plate 201. The upper end of the bottom through groove 205 is vertically connected to the side through groove 204. The lower end of the bottom through groove 205 extends downward through the bottom surface of the bottom plate 201. A bottom clamping groove 403 is formed at the bottom of the transverse clamping rod 402. The upper end of the longitudinal clamping rod 309 extends through the top surface of the top plate 301 and the bottom through groove 205 and can be clamped in the bottom clamping groove 403.
[0045] The push plate 308 is located in the side groove 306. After the clamping plate 408 is inserted into the side groove 306, it abuts against the push plate 308 and pushes the push plate 308 to move within the side groove 306. While the push plate 308 moves, the connecting rod 310 pushes the longitudinal clamping rod 309 upward along the rod groove 307 via the hinge shaft. This causes the longitudinal clamping rod 309 to pass through the top surface of the top plate 301 along the rod groove 307 and insert into the bottom through groove 205. This is used to lock the positioning block 303, the bottom plate 201 and the transverse clamping rod 402, ensuring the reliability of the connection between the bottom plate 2, the top plate 3 and the combined fixing member 4, thereby ensuring the reliability of the connection between adjacent static pressure piles 1.
[0046] Meanwhile, a bottom groove 403 is provided at the bottom of the transverse clamp 402, and the longitudinal clamp 309 matches the bottom groove 403, so that the longitudinal clamp 309 and the transverse clamp 402 are vertically inserted. This is used to further limit the transverse clamp 402 through the bottom groove 403, thereby further improving the connection reliability of the adjacent static pressure pile 1.
[0047] Please see the appendix Figure 6 The connecting rod 310 is arranged obliquely, and the connection end of the connecting rod 310 and the push plate 308 is lower than the connection end of the connecting rod 310 and the longitudinal locking rod 309.
[0048] The obliquely arranged connecting rod 310 can generate a vertical component force under the lateral thrust of the push plate 308, thereby applying a vertical force to the longitudinal locking rod 309 to ensure that the longitudinal locking rod 309 moves vertically along the rod groove 307.
[0049] Please see the appendix Figure 1 To be continued Figure 8 The connection method and working principle of the present invention for adjacent static pressure piles 1 are as follows:
[0050] The bottom plate 2 and the top plate 3 are installed simultaneously at the bottom and top of the static pressure pile 1 during the manufacturing process.
[0051] When connecting two adjacent static pressure piles 1, the positioning block 303 on the top plate 3 of the lower static pressure pile 1 is inserted into the positioning groove 203 of the bottom plate 2 of the upper static pressure pile 1. The four positioning blocks 303 and four positioning grooves 203 enable quick and accurate coaxial positioning and insertion of the two adjacent static pressure piles 1, ensuring the coaxiality and convenience of the connection of the static pressure piles 1.
[0052] Subsequently, two arc plates 401 are installed within the annular groove formed by the lower annular groove 202 of the base plate 201 and the upper annular groove 302 of the top plate 301. The two arc plates 401 are installed symmetrically and using the same installation method. The following explanation uses one arc plate 401 as an example:
[0053] During the installation of the arc plate 401, two push plates 411 pull the two movable plates 407 closer together. The spring 409 is compressed and stores force, causing the locking plates 408 to move closer together and retract into the movable groove 405. The two transverse locking rods 402 pass through the two side through grooves 204 and are inserted into the two side locking slots 304, and the insert plate 404 is inserted into the slot 305. Then, the two push plates 411 are released, causing the two locking plates 408 to move away from each other under the elastic force of the spring 409. The locking plates 408 pass through the side groove 406, through the movable groove 405, and are inserted into the side groove 306, thereby locking and fixing the bottom plate 201, the top plate 301, and the arc plate 401. During the process of inserting the clamping plate 408 into the side groove 306, the clamping plate 408 pushes the push plate 308 to move within the side groove 306. The connecting rod 310, which is set at an oblique hinge, pushes the longitudinal clamping rod 309 to move upward, so that it passes through the bottom through groove 205 and is just locked into the bottom clamping groove 403, further improving the clamping stability, thereby completing the connection combination of the two static pressure piles 1.
[0054] Multiple static pressure piles 1 can be connected and combined using the above method to meet the required service length of the static pressure piles 1. Disassembly is performed by reversing the steps described above; further details are omitted here.
[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
