[0026] Working principle: Prestressed pipe pile is a special type of structural engineering material used to enhance the bearing capacity of foundations and structures in civil engineering. A pile hole is opened at the end of the prestressed pipe pile, and the pile hole is exposed in the soil layer. The soil and stones above are mixed with rainwater and groundwater and scattered into the pile hole, blocking the pile core. After the earth excavation is completed, the blocked pile core needs to be manually cleaned so that concrete can be used for core filling. The pile core is often seriously blocked, and the efficiency of manual hole cleaning is low, and it consumes a lot of human resources. In addition, the quality of hole cleaning is poor, and it is difficult to clean the mud on the hole wall. In practice, the quality of hole cleaning does not meet the expected effect. For this reason, the bottom surface of the thin plate 5 and the surface of the positioning ring 3 can be fitted with each other in advance, and a plurality of limit bolts 7 are used to connect the threads of the threaded holes 4, so that the pipe pile body 1 and the steel plate 2 can be limited and fixed, and the embedded pile 6 can be embedded in the interior of the pile core. The steel plate 2 seals the pile core, and the soil cannot enter in the later stage. The hole cleaning process can be omitted, which is helpful to improve the efficiency of underground structural engineering, the pile hole is not polluted, the quality of the hole is guaranteed, and it is helpful To improve the quality of core filling, the plurality of support rings 12 can be rotated in the opposite direction to withdraw the limit bolt 7 from the inside of the threaded hole 4, so that the steel plate 2 and the pipe pile body 1 can be separated from each other, and the core filling can be continued. One end of the reinforcing rib 9 and the bottom surface of the triangular rib plate 11 are respectively abutted against the surface of the thin plate 5. Both are made of aluminum alloy material and have a certain hardness, thereby enhancing the external force resistance of the steel plate 2 and the thin plate 5. The L-shaped blocks 8 distributed at equal intervals make the compressive effect of the triangular rib plate 11 more comprehensive and extend the service life of the steel plate 2. During the pile foundation construction stage, before the last section of the pile is pressed in, a steel plate 2 is added to the top of the pile to protect the finished product, the pipe pile body 1 and the steel plate 2. After the excavation is completed, the steel plate 2 can be opened to carry out the core filling process, which greatly saves the pile hole processing time and shortens the construction period. The steel plate 2 can be recycled and reused in subsequent projects without cost increase. In order to avoid pile core blocking, the steel plate 2 can be installed at the end of the pipe pile body 1. When core filling is required, the steel plate 2 and the pipe pile body 1 can be separated from each other.
