Anchors for integrated pipe piles

Abstract

An anchor tensioner for integrated tubular piles, belonging to the technical field of pile foundations, provides an anchor tensioner for integrated tubular piles, including a set of prefabricated concrete components and pile armor, the prefabricated concrete components constitute the pile body, including Pile slats, anti-slip restraint rings, and end pressure seats. The pile slats are arranged vertically and circularly around the circumference of the annular pipe pile. The end pressure seat is located at the bottom of the integrated pipe pile and bears end resistance. The pile slabs are restrained and fixed. The anti-slip restraint ring is horizontally arranged at the upper and lower splicing positions of the pile slabs and constrains the vertical and radial displacement of the pile slabs. The anchor tensioner integrates each concrete component into a pile body. A is arranged on the periphery of the pile slab and the inner side of the pile hole wall soil, and transmits the normal pressure and frictional resistance of the pile hole wall soil. The invention reduces cost, facilitates construction, saves energy and protects the environment, improves quality, reduces on-site manual work, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to pile foundation technology, in particular to an anchor tensioner for an integrated pipe pile and a construction method for the pipe pile. Background technique [0002] Large-diameter piles in civil engineering are widely used in the foundations of buildings, bridges, ports and large structures. So far, the construction methods are mostly after drilling holes on site, then inserting steel cages into the pile holes, and pouring concrete on site. This method, under some extreme conditions, is difficult to construct, and the quality of concrete pouring is difficult to guarantee, and the construction speed is also slow. Especially in some karst cave areas, the concrete is easily lost into the soil (rock) cave before it solidifies, causing quality accident. However, for some large-diameter uplift piles, a large number of steel bars need to be configured, and the project cost is high. On the other hand, the core concrete of the larg...

Problems solved by technology

This method, under some extreme conditions, is difficult to construct, and the quality of concrete pouring is difficult to guarantee, and the construction speed is also slow. Especially in some karst cave areas, the concrete is easily lost into the soil (rock) cave before it solidifies, causing quality accident

For some large-diameter uplift piles, a large number of steel bars need to be configured, and the project cost is high.

On the other hand, the core concrete of the large-diameter concrete pile plays little or no role, resulting in waste of material

[0003] Existing prefabricated pipe piles generally have a small diameter and are mechanically placed in construction, so they are difficult to apply when encountering rock layers or hard soil layers
