Deep soft soil stratum underground station structure and construction method
The invention relates to the technical field of underground buildings and construction thereof, and discloses a deep soft soil stratum underground station structure and a construction method.The construction method comprises the steps that S1, three-axis stirring piles are constructed on the periphery of a preset station deep foundation pit underground diaphragm wall area; s2, an underground diaphragm wall is constructed on the inner side of the three-axis stirring pile in the preset station deep foundation pit area; s3, super-long cast-in-situ bored piles are constructed in the preset station deep foundation pit area, and the super-long cast-in-situ bored piles are connected with the bedrock layer; s4, a station deep foundation pit is excavated; s5, a station pile foundation bearing platform is constructed on the super-long cast-in-situ bored pile; s6, a station main body structure is constructed above the station pile foundation bearing platform; and S7, an artificial fill stratum is constructed above the station main body structure. The technical problem that in the prior art, the strength of a soft soil layer is not enough is solved, lateral deformation of the foundation pit can be effectively reduced, the safety and stability in the station excavation and construction process are guaranteed, engineering construction projects can be more smoothly propelled, and the construction efficiency is improved.
本申请涉及地下建筑物及其施工技术领域，并公开了一种深厚软土地层地下车站结构及施工方法，施工步骤包括：S1，在预设车站深基坑地下连续墙区域外围施工三轴搅拌桩；S2，在预设车站深基坑区域中的三轴搅拌桩内侧施工地下连续墙；S3，在预设车站深基坑区域中施工超长钻孔灌注桩，并使得超长钻孔灌注桩与基岩层连接；S4，开挖车站深基坑；S5，在超长钻孔灌注桩上施工车站桩基承台；S6，在车站桩基承台的上方施工车站主体结构；S7，在车站主体结构的上方施工人工填土层。本申请解决了现有技术中软土层强度不够的技术问题，可以有效减少基坑的侧向形变，并保证了车站开挖与建造过程中的安全性与稳定性，使工程建设项目能更顺利地推进，提高了施工效率。
