The invention provides an external support construction method of a subway deep foundation pit. The method comprises the following steps that a continuous wall is arranged in a continuous wall trench, a soil layer on the inner side of the continuous wall is used for constructing and generating the subway deep foundation pit, a supporting and pulling body is arranged on the continuous wall, a first end of the supporting and pulling body is fixed with the continuous wall, the continuous wall is tensioned towards the soil layer on the outer side of the continuous wall, the second end of the supporting and pulling body is fixed to the soil layer on the outer side of the continuous wall, the soil layer on the outer side of the continuous wall is tensioned towards the continuous wall, and therefore an inner supporting structure is effectively replaced, the construction efficiency is greatly improved, the construction safety is improved, the construction cost is reduced, especially, the soil layers on the outer sides of the continuous walls along the line of the subway deep foundation pit are firmly tensioned by the supporting and pulling bodies, the soil layer structure is reinforced, the stability of the soil layer structure around the subway along the line is enhanced, land subsidence accidents can be effectively reduced, an excellent environmental protection effect is achieved, the safety performance of buildings around the subway is remarkably improved, and benefits are brought to the nation and the people.
本发明提供一种地铁深基坑的外支撑施工方法，该方法通过在连续墙沟中设置连续墙，连续墙内侧的土层用于施工产生地铁深基坑，通过在连续墙上设置撑拉体，撑拉体的第一端与连续墙固定，将连续墙向连续墙外侧的土层拉紧，撑拉体的第二端与连续墙外侧的土层固定，将连续墙外侧的土层向连续墙拉紧，从而有效替代了内支撑结构，极大提升施工效率，提升施工安全，降低施工成本，尤其是地铁深基坑沿线的连续墙外侧的土层均被撑拉体牢牢拉紧，使得土层结构得以加固，加强了地铁沿线周边土层结构的稳固性，不仅可有效减少地陷事故的发生，而且还产生了优良的环境保护功效，让地铁周边的建筑安全性能显著提升，利国利民。
