Description

Technical Field

[0001] The utility model relates to the technical field of PHC pipe pile connection structures, in particular to a PHC pipe pile connection structure. Background Art

[0002] PHC piles, or prestressed high-strength concrete piles, are made using a pre-tensioned prestressed centrifugal forming process and are cured by steam at 10 atmospheres (about 1.0Mpa) and 180°C to form a hollow cylindrical precast concrete component with a standard section length of 10m, a diameter of 300mm to 800mm, and a concrete strength grade of ≥C80.

[0003] When a single section of pipe pile cannot reach the length specified in the design, multiple sections of pipe piles need to be spliced ​​together to meet the demand. In order to ensure the bearing capacity of the pipe piles after splicing and avoid the pipe piles from breaking due to the displacement of the position during piling, workers are usually required to align the connection parts of the two pipe piles and then weld them together. When welding current pipe piles, workers usually need to frequently adjust the position of the pipe piles to keep them aligned, which affects work efficiency. After the splicing is completed, workers are required to insert the pipe piles into the soil. However, during the piling process, the soil will directly contact the connector and generate friction, which will scrape off part of the anti-rust coating on the surface of the connector, affecting the anti-rust effect of the connector, and further affecting the service life of the connector.

[0004] Therefore, we made improvements and proposed a PHC pipe pile connection structure. Utility Model Content

[0025] Among them, the position and size of the positioning plate 4 match the position and size of the positioning groove 10. After the two pipe piles are moved to a roughly aligned position, the position of the positioning plate 4 is aligned with the positioning groove 10 by translating and rotating the position of the pipe pile at the upper end, and the positioning plate 4 is inserted into the positioning groove 10 to achieve preliminary alignment of the two pipe piles.

[0026] The position and size of the block 7 match the position and size of the slot 13. The engagement of the block 7 with the slot 13 enables the first annular baffle 6 and the second annular baffle 12 to be aligned and fixed, thereby reducing friction at the connection between the soil and the pile.

[0027] Among them, the length of the first annular baffle 6 and the length of the second annular baffle 12 are both greater than the length of the upper connecting member 2 and the lower connecting member 8. A pair of openings 14 are symmetrically provided on both sides of the top of the upper connecting member 2 and both sides of the bottom of the lower connecting plate, and the openings 14 are respectively connected to the first annular groove 5 and the second annular groove 11 at the corresponding positions. When welding, the staff pulls the pulling block 15 to drive the first annular baffle 6 to move upward and the second annular baffle 12 to move downward, and installs the bolts into the mounting holes to fix the first annular baffle 6 and the second annular baffle 12 to avoid obstruction during welding and coating of the anti-rust layer. After the anti-rust layer is coated, the bolts are removed, the first annular baffle 6 is pushed downward and the second annular baffle 12 is pushed upward, so that the first annular baffle 6 and the second annular baffle 12 are tightly together, and the bolts are screwed into the mounting holes, thereby protecting the pipe pile connection.

[0031] The surfaces of the upper connecting member 2 and the lower connecting member 8 are both provided with an anti-rust layer to reduce the corrosion damage of the pipe pile after long-term use.

[0032] Working principle: When using this type of PHC pipe pile connection structure, the staff moves the two pipe piles to a roughly aligned position, and then aligns the positioning plate 4 with the positioning groove 10 by translating and rotating the position of the pipe pile at the upper end, and inserts the positioning plate 4 into the positioning groove 10 to achieve preliminary alignment of the two pipe piles. At this time, pull the pulling block 15 to drive the first annular baffle 6 to move upward and the second annular baffle 12 to move downward, and install the bolts into the mounting holes to fix the first annular baffle 6 and the second annular baffle 12 to avoid obstruction during welding and coating of the anti-rust layer. After the anti-rust layer is coated, remove the bolts, push the first annular baffle 6 downward and push the second annular baffle 12 upward, so that the first annular baffle 6 and the second annular baffle 12 are tightly together, and screw the bolts into the mounting holes to fix the first annular baffle 6 and the second annular baffle 12, thereby protecting the pipe pile connection.
