Construction method of prestressed pipe pile and locating hoop

Abstract

The invention relates to a construction method of a prestressed pipe pile and a locating hoop. The locating hoop for the prestressed pipe pile comprises a locating ring, a limiting ring and two limiting bases, wherein the locating ring is arranged on the outer side of an upper section pile in a sleeving manner, the limiting ring is arranged on the outer side of a lower section pile in a sleeving manner, and the two limiting bases are used for carrying electrode holders. The locating ring is divided into two locating plates in a semi-ring shape. The ends of the two locating plates are connectedin a rotating manner, and the other ends of the two locating plates are detachably connected. The two limiting bases are connected with the locating ring in a sliding manner in the peripheral direction of the locating ring. The limiting ring is divided into two limiting plates in a semi-ring shape. The ends of the two limiting plates are connected in a rotating manner, and the other ends of the two limiting plates are detachably connected. The locating ring and the limiting ring are connected through a limiting rod. The two ends of the limiting rod are connected with the locating ring and thelimiting ring in a sliding manner in the periphery direction of the locating ring. By arranging the locating ring and the limiting ring, the purpose of improving construction work efficiency is achieved. According to the construction method of the prestressed pipe pile, by the adoption of the locating hoop, time for pile connecting of construction personnel is shortened, and the purpose of improving the construction work efficiency is achieved.

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 prior art, 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. [0004] The abov...

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
