Construction method of foundation pit enclosure structure located in underground space of existing building
The invention discloses a construction method of a foundation pit enclosure structure located in an underground space of an existing building. The construction method comprises the following steps that the position of the enclosure structure located in the underground space of the existing building is determined; a soil body below a bottom plate is reinforced or foundation underpinning reinforcement is conducted on the bottom plate; in the underground space, partition walls are constructed along the two sides of the area of the enclosure structure to be constructed correspondingly; a buttresscolumn or a supporting structure is arranged on the outer side of the enclosed area of the two partition walls; a top plate and the bottom plate in the area of the enclosure structure to be constructed are sequentially broken; and the enclosure structure is constructed in the enclosed space of the two partition walls. The construction method has the advantages that it can be ensured that the existing building (structure) can be transformed as needed and is not damaged, the enclosure structure can be effectively constructed according to a normal construction process, required construction machinery is simple, the operation difficulty is low, the construction measure cost is low, the influence on the surrounding environment is small, and the comprehensive effect is remarkable.
本发明公开了一种位于既有建构筑物地下空间的基坑围护结构施工方法，包括以下步骤：确定位于既有建构筑物地下空间的围护结构位置；将底板下方的土体进行加固补强或对底板进行基础托换加固；在地下空间内，沿待施工的围护结构的区域两侧分别施作一道隔墙；在两道隔墙的围合区域外侧设置扶壁柱或支撑结构；依次破除待施工的围护结构区域内的顶板和底板；在两道隔墙的围合空间内施作围护结构。本发明的优点是：既能确保既有建筑（构）筑物能够按需改造且不被损坏，又能有效地按正常施工工艺实施围护结构，而且其所需要的施工机械简单，操作难度小，施工措施成本小，对周边环境影响小，综合效果显著。
