AI Technical Summary

Technical Problem

In existing technologies, the concrete properties of pipe piles formed by centrifugal molding differ significantly from those formed by ordinary vibration molding. This results in the inability to detect the concrete by extracting core samples from the pile body, which damages the integrity of the pipe pile body and the prestressed steel bars, affecting its mechanical properties and causing the pipe pile to be scrapped.

Method used

Design a pipe pile forming mold that facilitates core sampling inspection. It includes an upper mold and a lower mold, with a sampling section and a forming section inside. The connecting section enables synchronous tensioning and centrifugal forming of the sampling cage and the reinforcing cage, ensuring that the core sample can accurately reflect the quality of the pipe pile concrete. The connection structure between the fan-shaped plate and the pressing spring facilitates quick assembly and disassembly.

Benefits of technology

It enables testing without damaging the pipe pile body and prestressed steel bars, ensuring the accuracy of test results, avoiding the scrapping of pipe piles, significantly saving production costs, and the connection structure is simple, reliable, and easy to assemble and disassemble.

Abstract

A pipe pile forming die convenient for core sample detection relates to the field of pipe pile concrete forming, and comprises an upper die and a lower die, and a cylindrical forming space formed by the two, an end plate is arranged on the lower die, a tensioning part is arranged on the end plate, a sampling part for sampling detection is arranged in the lower die, a forming part for forming a pipe pile is also arranged in the lower die, a connecting part is arranged between the sampling part and the forming part, and the two are connected through the connecting part, so that synchronous tensioning is realized, the sampling cage and the steel reinforcement cage are synchronously tensioned and formed by the same mold, the core sample prepared in the sampling cage can truly and accurately reflect the concrete quality of the pipe pile entity, and the problem that the pipe pile centrifugal concrete cannot be replaced by standard test blocks for detection is solved.
