Construction method of latticed underground diaphragm wall adopting pile type nodes
The invention relates to a construction method of a latticed underground diaphragm wall adopting pile type nodes, a cast-in-situ bored pile is constructed at each node position of the underground diaphragm wall as a node of the underground diaphragm wall, the diameter of the pile of the cast-in-situ bored pile is larger than the thickness of the underground diaphragm wall, the bottom elevation of the pile is located at a certain depth below the bottom elevation of the underground diaphragm wall, and the bottom elevation of the pile is larger than the thickness of the underground diaphragm wall. An underground diaphragm wall groove section is constructed between every two piles, when the underground diaphragm wall groove sections are subjected to groove milling, joint notches are milled in the side walls of the notch sections of the piles together, then a groove section reinforcement cage is put down, concrete is poured, all nodes are connected, and the latticed underground diaphragm wall structure is formed. When the underground diaphragm wall joint is constructed, groove holes do not need to be excavated, the hole collapse risk and the concrete streaming problem existing in the traditional technology construction process are fundamentally avoided, and the joint is large in rigidity, good in anti-seepage effect, high in construction speed and low in cost.
本发明涉及一种采用桩柱式节点的网格状地下连续墙施工方法，在地连墙每个节点位置施工钻孔灌注桩作为地连墙节点，钻孔灌注桩的桩柱直径大于地连墙的厚度，桩柱底部标高位于地连墙底部标高以下一定深度，在每两个桩柱间施工地连墙槽段，地连墙槽段铣槽时，一并在桩柱槽口段侧壁上铣削出接头槽口，然后下放槽段钢筋笼、浇筑混凝土，连接各节点，形成网格状地连墙结构。本发明在地连墙节点施工时不需要开挖槽孔，从根本上避免了传统工艺施工时存在的塌孔风险以及混凝土绕流问题，且节点本身刚度大，抗渗效果好，施工速度快，成本低。
