DETAILED DESCRIPTION

[0024] like Figures 1-4 As shown, a reusable PLC pile crown beam reinforcement device includes supporting steel pipe piles 6 and steel sheet piles 4 positioned between adjacent steel pipe piles 6. The steel pipe piles 6 and the steel sheet piles 4 form a PLC composite pile support. One or more locking buckles 3 are welded to the outer wall of the steel pipe piles 6 in a circular array. The locking buckles 3 engage with both sides of the steel sheet piles 4. A buckle 2 is also fixed to the outer wall of the steel pipe piles 6. The buckle 2 includes a body 21 welded to the outer wall of the steel pipe piles 6. Two positioning protrusions 22 are provided on the inner side of the body 21. Connecting rods 24 are mounted on the two positioning protrusions 22. A reinforcement member 25 is provided above the connecting rod 24. Baffles 26 are slidably mounted on both ends of the reinforcement member 25. The combination of the reinforcement member 25 and the baffle 26 effectively distributes the load and enhances the load resistance of the PLC pile crown beam.

[0025] Construction process:

[0026] 1) Installation of steel pipe piles 6 and steel sheet piles 4: First, drill holes in the predetermined locations and install the steel pipe piles 6, ensuring their verticality and flatness. Insert the steel sheet piles 4 into the reserved space between the steel pipe piles 6, so that the locks 3 fit on both sides of the steel sheet piles 4.

[0027] 2) Installing Reinforcement 25: Install clip 2 on the outside of steel pipe pile 6, ensuring that positioning protrusion 22 fits tightly against the steel pipe pile 6. Pass connecting rod 24 through clip 2 and secure it. Install reinforcement 25 above connecting rod 24. Slide baffles 26 onto both ends of reinforcement 25 using the guide slots, adjust the position, and secure.

[0028] 3) Internal support construction: A second I-beam 5 is used as an internal support rod in the combined pile support formed by the steel pipe pile 6 and the steel sheet pile 4 to form a crown beam.

[0029] After the inner support is constructed, the reinforcement 25 can effectively enhance the overall structural stability of the crown beam, and the baffle 26 can prevent the PLC pile recovery slot from being stuck by soil or stones in the later stage.

[0030] Through the setting of profile steel bars and reinforcing devices, the bearing capacity of the PLC pile crown beam is significantly improved, which can bear larger load. The design of the lock catch 3 and the buckle 2 enhances the connection between the steel pipe pile 6 and the steel sheet pile 4, improves the overall stability of the structure, and simplifies the construction process and reduces the complexity of the on-site operation. The reinforcing member 25 can effectively strengthen the overall structural stability of the crown beam, and the baffle 26 can prevent the PLC pile from being stuck in the slot during the later recycling of the structure, thereby prolonging the service life of the structure.

[0031] As shown in Figure 3 , preferably, the two positioning protrusions 22 form an open circular arc structure, and a threaded groove is arranged inside. The rod body of the connecting rod 24 is provided with a threaded part 23 near the lower part, and the threaded part 23 is threadedly connected with the threaded groove.

[0032] As shown in Figure 3 , each positioning protrusion 22 presents an open circular arc structure and is made of welded alloy steel material to ensure its strength and durability. The inside of each positioning protrusion 22 is provided with a threaded groove, which is designed according to the M16 standard and has a depth of 5 mm, which can effectively cooperate with the threaded part 23 of the connecting rod 24.

[0033] As shown in Figure 3 , the rod body of the connecting rod 24 is provided with a threaded part 23 near the lower part, and the length is adapted to the positioning protrusion 22 to ensure the close connection between the threaded part 23 and the threaded groove.

[0034] During the assembly process, the threaded part 23 is connected with the threaded groove inside the positioning protrusion 22 by rotating the connecting rod 24, forming a firm connection to prevent loosening during construction and use.

[0035] Pre-assembly steps:

[0036] 1), Fix the positioning protrusion 22 to the outside of the steel pipe pile 6 to ensure its positioning accuracy and stability. Prepare several connecting rods 24 and process threaded parts 23 at the lower part to facilitate connection with the threaded groove of the positioning protrusion 22.

[0037] 2), At the construction site, the worker aligns the threaded part 23 of the connecting rod 24 with the threaded groove of the positioning protrusion 22 and rotates to complete the connection. By using a torque wrench, it is ensured that the threaded connection reaches the specified torque value to ensure the firmness of the connection.

[0038] 3), After completing the installation of the steel pipe pile 6 and the steel sheet pile 4, check the connection part to ensure that all connecting rods 24 are tightly combined with the threaded groove of the positioning protrusion 22, avoiding any loosening phenomenon.

[0039] The open arc structure and the thread groove can better combine the connecting rod 24 and the positioning protrusion 22, improve the overall connection stability, reduce the loosening phenomenon under the action of dynamic load such as earthquake through thread connection, and improve the anti-seismic performance.

[0040] The bottom of the reinforcing part 25 is provided with a positioning hole, and the positioning hole is inserted and matched with the top of the connecting rod 24.

[0041] In the above structure, the bottom of the reinforcing part 25 is provided with a positioning hole, and the connecting rod 24 is inserted and matched with the top of the connecting rod 24, so that the stability of the connection is realized, and after reinforcement, the reinforcing part 25 can be taken out through the insertion mode, and the connecting rod 24 is located on the top of the corbel and combined with the steel pipe pile 6 to form a sufficient covering and reinforcing area on the top of the corbel.

[0042] In this process, in order to further improve the utilization of cost, the connecting rod 24 can be connected in sections, and the adjacent branches of the connecting rod 24 are connected through thread connection or insertion mode, and the connecting rod 24 can be removed according to different situations in the later period to realize the turnover and reutilization of the PLC pile and the reinforcing assembly.

[0043] As shown in Figure 4 The reinforcing part 25 is provided with a clamping groove on the side close to the outside, the position of the clamping groove of the reinforcing part 25 is specifically provided on the side close to the outside of the reinforcing part 25, a baffle 26 is slidably connected at the clamping groove, the baffle 26 is a rectangular steel plate, and the baffle 26 is slidably connected at both ends of the reinforcing part 25 through the clamping groove to form a transverse support.

[0044] As shown in Figure 4 Preferably, the clamping groove is an insertion hole 28, the insertion hole 28 is provided along the length direction of the reinforcing part 25 and penetrates the reinforcing part 25 completely, so that the installation of the insertion rod 27 is facilitated. Correspondingly, the side of the baffle 26 is connected with the insertion rod 27, the insertion rod 27 is a cylinder, the insertion rod 27 is inserted into the insertion hole 28, so that the baffle 26 can slide left and right, and the stability of the connection is ensured. Through the connection of the insertion rod 27, the baffle 26 can freely slide at the clamping groove, the position of the baffle 26 is adjusted, a transverse support is formed, and the baffle 26 enhances the lateral force resistance of the supporting structure.

[0045] Through the insertion of the positioning hole and the top of the connecting rod 24 and the sliding connection of the clamping groove and the baffle 26, the overall stability of the PLC pile corbel is significantly improved.

[0046] The combination of the insertion hole 28 and the insertion rod 27 simplifies the installation and adjustment process of the baffle 26, and reduces the construction time and difficulty.

[0047] The sliding combination of the baffle 26 in the clamping groove makes the position of the baffle 26 adjustable according to specific construction requirements, improving the adaptability and adjustability of the structure.

[0048] As shown in Figure 4 The front surface of the baffle 26 is provided with an inwardly recessed inner groove 29, and a spacing component is filled in the inner groove 29 for maintaining pressure balance when the baffle 26 is supported. The surface of the inner groove 29 is treated to prevent slipping to increase the contact area with the spacing component.

[0049] The spacing component is a support pad made of rubber or polyurethane material, which has a certain elasticity and buffering effect, can effectively absorb and disperse the pressure from the baffle 26, maintain balance, and prevent local overload.

[0050] The cooperation between the inner groove 29 and the spacing component makes the baffle 26 better fit the construction object during support, evenly distributes the applied pressure, and avoids local stress concentration.

[0051] As shown in Figure 1 The outer side of the buckle 2 is provided with two groups of first I-shaped steel 1 (large I-shaped steel), which are mirror-symmetrically arranged, and a filling space is arranged between the two first I-shaped steel 1, and a second I-shaped steel 5 (small I-shaped steel) is arranged at a preset angle.
