Construction method of stud piles in pebble bed

Abstract

The invention discloses a construction method of stud piles in a pebble bed. The method comprises the following steps: forming stud pile holes on the ground; vertically putting steel tubes into the stud pile holes, wherein the stud piles include the steel tubes and concrete poured inside and outside the steel tubes; reserving pouring gaps between the lower ends of the steel tubes and the bottoms of the pile holes; carrying out concrete pouring directly from the inner lower ends of the steel tubes, wherein part of the concrete enters the space between the outside of the steel tubes and the stud pile holes via the pouring gaps and gradually accumulates upwards, and the rest concrete accumulates upwards from the inner lower ends of the steel tubes, thus completing synchronous pouring of the inside and outside of the steel tubes and achieving pile forming. The construction method has the following beneficial effects: pouring can be carried out inside and outside the steel tubes simultaneously, and a structure capable of automatically limiting the ascending of concrete is formed outside the steel tubes, thus ensuring the continuity of pouring and the compactness of the concrete outside the steel tubes, being good in overall bonding property after pile forming and being good in structural strength.

Description

technical field [0001] The invention belongs to the field of column pile construction methods, in particular to a column pile construction method in a dense pebble layer. Background technique [0002] In the field of construction, it is often necessary to set column piles on the foundation. The column piles are structural columns of buildings and belong to load-bearing columns of buildings. It needs to be completed before the excavation. During the excavation, it will support the roof of the building. After it is built, it will be the permanent supporting member of the building. The current type of column pile structure has a core steel cylinder in the middle, and the inside and outside of the steel cylinder are concrete, and the concrete in the steel cylinder is usually higher than the concrete outside the steel cylinder. Yet this kind column pile structure is still lacking in aspect such as the continuity of concrete perfusion, completeness, integral strength, fixation ef...

AI Technical Summary

Problems solved by technology

However, this kind of column pile structure is still lacking in the continuity and integrity of concrete pouring, the overall strength, and the fixing effect during construction.
