Existing building reconstruction method
The invention relates to an existing building reconstruction method. The existing building reconstruction method comprises the following steps that a, support construction is conducted: an underground diaphragm wall is arranged underground at the periphery of an existing building, and waterproof construction is performed on the underground diaphragm wall; b, support construction is conducted, specifically, soil in the underground diaphragm wall is excavated till an existing building bearing platform is exposed, and a horizontal temporary support is constructed between the existing building bearing platform and the underground diaphragm wall; c, excavation construction is conducted, specifically, the soil body below the existing building is excavated out, and opening of a basement space is completed; d, basement construction is conducted, wherein a basement bottom plate, an outer wall and a top plate are poured in the basement space, and the basement bottom plate and the top plate are both integrally poured with existing building bearing piles; and e, soil is backfilled on the outer side of a basement, and the horizontal temporary support is removed. The method has the effects that the available area of the existing building is increased, and the structural stability of the modified existing building is guaranteed.
本申请涉及一种既有建筑改造方法，其包括以下步骤：a.支护施工：在既有建筑外围地下设置地下连续墙，并对地下连续墙进行防水施工；b.支撑施工：开挖地下连续墙内土体至露出既有建筑承台，在既有建筑承台和地下连续墙之间施工水平临时支撑；c：挖掘施工：挖除既有建筑下方土体，完成地下室空间的开辟；d：地下室施工：在地下室空间内浇筑地下室底板、外墙和顶板，地下室底板和顶板均与既有建筑承载桩浇筑为一体；e：地下室外侧回填土，并拆除水平临时支撑。本申请具有增加既有建筑可用面积，并保证既有建筑改造后结构稳定性的效果。
