Underground garage junction reverse construction method
The invention relates to the technical field of building construction, in particular to an underground garage junction reverse construction method which comprises the following steps: confirming or optimizing a boundary between a first-stage underground garage and a second-stage underground garage, and setting the boundary near a column net; the structural design is optimized, and underground garage frame columns at the boundary are optimized into cast-in-situ bored piles with the same section; the cast-in-situ bored piles are incorporated into a foundation pit supporting system to replace part of a vertical supporting structure, and the foundation pit supporting design is optimized; boundaries for staged construction of the underground garage are arranged at a column net as far as possible, drawing optimization is completed in advance, originally-designed concrete frame columns are optimized into cast-in-situ bored piles with built-in steel pipe core columns, the foundation pit supporting function is provided during first-stage construction of the underground garage, it can be guaranteed that the space of an upper floor of the underground garage is expanded, and the using function is met; therefore, the construction difficulty is reduced, the construction cost is reduced, and the safety of a building is ensured.
本发明涉及建筑施工技术领域，具体为一种地下车库交界处逆作施工方法，包括：确认或优化一期地下车库与二期地下车库的分界线，将分界线的划定设在柱网附近；对结构设计进行优化，分界线处的地下车库框架柱优化为同等截面的钻孔灌注桩；将钻孔灌注桩纳入基坑支护体系，代替部分垂直支护结构，优化基坑支护设计；将地下车库分期建设的分界线尽可能设置在柱网处，提前完成图纸优化，将原设计混凝土框架柱优化为内置钢管芯柱的钻孔灌注桩，在一期地下车库施工时提供基坑支护的功能，又能保证地下车库上部楼层的空间得以扩充，满足使用功能，从而降低了施工难度，降低了工程造价，并保证了建筑的安全。
