Ultra-long empty drilling wall-connecting grooving construction method
The invention discloses an ultra-long empty drilling wall-connecting grooving construction method. The ultra-long empty drilling wall-connecting grooving construction method comprises the following steps that S1, a guide wall is constructed; S2, slurry is prepared; S3, grab bucket grooving is carried out; S4, a main cage is hung and placed; S5, auxiliary I-shaped steel of an auxiliary cage is hoisted, specifically, the auxiliary I-shaped steel of the auxiliary cage and the main cage are spliced into a whole reinforcement cage at a notch, and the reinforcement cage is hoisted into the notch in place; S6, concrete is poured; and S7, a cavity section is backfilled, and the steps S3-S7 are repeated until the construction of the last underground diaphragm wall is completed. The auxiliary cage and the auxiliary I-shaped steel are adopted, a lower underground diaphragm wall structure can be firstly constructed for some special projects, then an upper soil nailing wall and other supporting structures can be constructed in an earth cutting mode, underground diaphragm wall construction can be carried out in advance when a site is narrow, operation is easy, safety and reliability are achieved, the construction efficiency is improved, and the engineering cost is further saved.
本发明公开了一种超长空钻连墙成槽施工方法，包括以下步骤：S1、导墙施作；S2、泥浆制备；S3、抓斗成槽；S4、主笼吊放；S5、副笼副工字钢吊放：副笼副工字钢与主笼在槽口拼接成整体的钢筋笼，并将钢筋笼吊装入槽到位；S6、浇筑混凝土；S7、空腔段回填；重复步骤S3～S7直至最后一幅地下连续墙施工完毕。采用副笼副工字钢，对一些特殊的项目能够先施工下部地下连续墙结构，再挖土施工上部的土钉墙等支护结构，在场地狭小时可以提前进行地下连续墙施工，操作简单、安全可靠，既提高了施工效率，也节约了工程成本。
