Deep foundation pit engineering main building area post-dismantling supporting structure and construction method
The invention relates to the technical field of deep foundation pit construction, in particular to a deep foundation pit engineering main building area post-dismantling supporting structure and a construction method of the post-dismantling supporting structure. According to the post-dismantling supporting structure, a foundation pit side wall protection structure is formed by constructing row piles on the edge of a foundation pit, stand columns distributed in a circular mode are constructed in the middle of the foundation pit to form a foundation pit inner side supporting and retaining structure, and a horizontal supporting component is arranged between the foundation pit side wall protection structure and the foundation pit inner side supporting and retaining structure, so that a supporting and retaining structure in the prior art is optimized; interference on excavator equipment for earthwork operation is avoided, and the foundation pit excavation efficiency is improved. The post-dismantling supporting structure is kept until the pouring of the underground building structure is completed, and the horizontal supporting part between the foundation pit side wall protection structure and the foundation pit inner side supporting structure in the foundation pit is gradually dismantled while the building main body structure is upwards constructed, so that the operation of dismantling the supporting structure is independently constructed, and the overall construction progress is accelerated.
本发明涉及深基坑施工技术领域，具体涉及一种深基坑工程主楼区域后拆支撑结构及后拆支撑结构的施工方法。该后拆支撑结构在基坑的边沿通过构筑排桩形成基坑侧壁防护结构，在基坑的中部构筑圆形排布的立柱形成基坑内侧支挡结构，并在基坑侧壁防护结构与基坑内侧支挡结构之间布置水平支撑部件，优化了现有技术中的支护结构，避免了对进行土方作业的挖机设备形成干涉，提高了基坑开挖的效率。后拆支撑结构一直保留到地下建筑结构浇筑完成，在建筑主体结构向上施工的同时，逐步拆除基坑中基坑侧壁防护结构与基坑内侧支挡结构之间的水平支撑部件，使得拆除支撑结构的作业独立施工，加快了整体施工进度。
