Construction method for synchronously implementing underground reverse construction method and overground structure sequential construction
The invention provides a construction method for synchronously implementing an underground reverse construction method and overground structure sequential construction. The construction method comprises the following steps that construction operation of an underground enclosure structure continuous wall is conducted, specifically, the wall toe of the continuous wall is arranged on a clay layer, and the continuous wall is connected in an end-to-end mode to enable an enclosure structure to be fully closed; construction operation of a core tube continuous wall is conducted, specifically, the continuous wall is arranged in a disconnected mode, a fracture surface is reserved for a hole, and the wall toe of the continuous wall is arranged in a pebble layer; one pile and one column are constructed; excavation is conducted for the first time to a structural bottom plate, and straight thread connection of a structural concrete top plate beam, a column structure and the underground enclosure structure continuous wall is completed; the underground core tube continuous wall is connected with the column structure and the beam plate, at the moment, structural waterproof parts are laid at the bottom of a top plate along the wall top of the peripheral underground enclosure structure continuous wall, structural side walls are hung on the wall top of the underground enclosure structure continuous wall in a supported mode to form movable supporting points, and structural side wall steel bars are buried into lower-layer earthwork; and the structural steel bars, steel pipe columns and a core shaft structure form structural connection, and the structural bottom plate and the structural side walls of the second underground layer are integrally poured.
本发明提供地下逆作法与地上结构顺作同步实施的工法，包括如下步骤：地下围护结构连续墙施工作业，将连续墙的墙趾设置于粘土层，连续墙首位连接使得围护结构全封闭；核心筒连续墙施工作业，连续墙断开设置，为洞口预留断面，该连续墙墙趾设置卵石层中；施工一桩一柱；初次开挖到结构底板，通过完成结构混凝土顶板梁与柱结构、及地下围护结构连续墙直螺纹连接；将地下核心筒连续墙与柱结构及梁板形成连接，此时应将结构防水沿外围地下围护结构连续墙墙顶铺设于顶板的底部并且将结构侧墙支挂于地下围护结构连续墙墙顶形成活动支点，结构侧墙钢筋埋入下层土方；结构钢筋与钢管柱、核心井筒结构形成结构联接整体浇注地下二层的结构底板及结构侧墙。
