Construction method and positioning hoop of prestressed pipe pile

Abstract

The invention relates to a construction method of a prestressed pipe pile and a positioning hoop. A positioning hoop for a prestressed pipe pile includes a positioning ring sleeved on the outer side of an upper section pile, a limiting ring sleeved on the outer side of a lower section pile, and a To undertake the two limit seats of the welding tongs, the positioning ring is divided into two semi-circular positioning plates, one end of the two positioning plates is connected by rotation, and the other end is detachably connected, and the two limit seats are aligned with the positioning ring along the circumferential direction of the positioning ring. Sliding connection, the limit ring is divided into two semi-circular limit plates, one end of the two limit plates is connected by rotation, and the other end is detachably connected, the positioning ring and the limit ring are connected by a limit rod, and the two limit rods The locating rings at both ends are connected with the locating rings and the limiting rings in a sliding manner respectively in the circumferential direction. Through the setting of the positioning ring and the limit ring, the purpose of improving the construction work efficiency is realized; a construction method of the prestressed pipe pile, by using the positioning hoop, the pile connection time of the construction personnel is reduced, and the purpose of improving the construction work efficiency is realized.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a prestressed pipe pile and a positioning hoop. Background technique [0002] Prestressed pipe piles are generally used as pile foundations for buildings and the like. [0003] In the existing technology, such as figure 1 As shown, the prestressed tubular pile includes a cylindrical pile body 800 and a pile head 810 . During construction, since the pile length of the building is usually more than 30m, and the length of the prestressed pipe pile is generally less than 15m, so the method of superimposing multiple piles is used to increase the length of the pile during the construction of the prestressed pipe pile. The connection between adjacent prestressed pipe piles generally adopts the method of welding the pile heads at both ends, and the axial misalignment distance of the upper and lower prestressed pipe piles is less than 2mm.

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the adjacent prestressed pipe piles are welded and positioned, after the prestressed pipe piles to be pressed in are positioned first, the prestressed pipe piles to be pressed in are first manually aligned, and then steel The bar pries the lower section of the prestressed pipe pile from different directions. After several times of prying, the upper and lower sections of the prestressed pipe pile can be aligned. However, the operation method lasts for a long time, resulting in low construction work efficiency
