Underground continuous pile construction process
The underground continuous pile construction technology comprises the following steps that S1, a guide wall is constructed; s2, performing groove section division on the guide wall according to the designed framing graph, and determining the construction position of each groove section; the construction groove section comprises a first open width, a connecting width and a closed width; s3, grooving construction is conducted, specifically, a direct grabbing technology is adopted for grooving, a hydraulic grooving machine is adopted for directly grabbing a soil layer till the designed depth is reached, and slurry is adopted for protecting the wall; s4, circular reinforcement cages are sequentially put down in the grooves according to the set intervals, and concrete is poured to build a unit pile body; the method is carried out section by section, a continuous enclosure structure is formed, the method is suitable for shallow foundation pits, the manufacturing cost is low, and concrete loss is avoided while the construction requirement is met.
本发明提出地下连续桩施工工艺，包括以下步骤：S1、导墙施工；S2、根据设计的分幅图对导墙进行槽段划分，确定每幅槽段的施工位置；施工槽段包含有首开幅、连接幅、闭合幅；S3、成槽施工，成槽采用直抓工艺，采用液压成槽机直接抓取土层，直至抓至设计深度，采用泥浆护壁；S4、在成槽内按照设定的间距依次下放圆形钢筋笼，浇筑混凝土筑成一个单元桩体；如此逐段进行，形成一道连续的围护结构，适用于浅基坑，造价低，满足施工要求的同时，无混凝土损耗。
