Supporter exchanging method for stage construction basement using cast-in-situ bored piles as separation palisade

Abstract

The invention provides a supporter exchanging method for a stage construction basement using cast-in-situ bored piles as a separation palisade. The method comprises the following steps: step 1) constructing a separation palisade structure using the cast-in-situ bored piles as a main body, inserting supporter exchanging profile steels between the adjacent cast-in-situ bored piles, and embedding one end of each of the supporter exchanging profile steels into a basement floor and a transmission belt of a first-stage basement; step 2) embedding the other end of the supporter exchanging profile steels into the basement floor of a second-stage basement when casting the basement floor of the second-stage basement; and step 3) disassembling the cast-in-situ bored piles and the transmission belt, keeping the supporter exchanging profile steels, strapping connection steel bars and casting concrete, so as to connect the first-stage basement with the second-stage basement. The supporter exchanging problem of the early-stage and later-stage construction parts is solved well, and the supporter exchanging effect is good; in addition, the basement structure is constructed in sequence, the construction is convenient, and the supporter exchanging cost is low.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a support replacement method for a staged construction basement using bored cast-in-place piles as partition enclosures. Background technique [0002] In the basement construction of building construction projects, due to reasons such as site, safety or funds, it is often necessary to carry out staged construction. The bored piles are often used as the separation enclosure structure for staged construction. After the construction is completed, the bored piles will be removed. The period basement is integrated. In order to ensure that the basement can be connected to each other as a whole, it is necessary to deal with the problem of changing the support in the early and late construction parts. At present, the method of reverse work is usually adopted, that is, the bored piles are removed successively from top to bottom as the construction progresses, so as to connect the fro...

AI Technical Summary

Problems solved by technology

At present, the method of reverse work is usually adopted, that is, the bored piles are gradually removed from top to bottom as the construction progresses, so as to connect the front and later basements. The construction is more troublesome and the replacement cost is high.
