Soft stratum deep foundation pit excavation construction method
The invention discloses a soft stratum deep foundation pit excavation construction method, and belongs to the technical field of building engineering. The soft stratum deep foundation pit excavation construction method comprises the following specific steps that (1) foundation pit dewatering is conducted, specifically, dewatering well construction is conducted before a foundation pit is excavated,and a mode of combining separation, dewatering and drainage is adopted; (2) foundation pit excavation is conducted, specifically, foundation pit excavation construction is conducted through an open excavation method, wherein segment-by-segment excavation is conducted in the longitudinal direction according to the preset length, and layering and segment-by-segment excavation are conducted in the transverse direction; (3) foundation pit supporting is conducted, specifically, concrete supporting and steel supporting are included; and (4) construction monitoring is conducted, specifically, foundation pit enclosure structure system monitoring, surrounding environment monitoring and on-site inspection and observation are included. According to the soft stratum deep foundation pit excavation construction method, foundation pit dewatering adopts the mode of combining separation, dewatering and drainage, and a draining well is arranged in the foundation pit for dewatering, so that the construction quality of a dewatering well is guaranteed; a dry working surface of foundation pit construction is further ensured; foundation pit supporting adopts concrete supporting and steel supporting, andthus it is guaranteed that a foundation pit support system is timely and stable; and construction monitoring is matched with an informatization monitoring technology, and the purposes of high quality, safety, economy and reasonableness are achieved.
一种软弱地层深基坑开挖施工方法，属于建筑工程技术领域。它包括以下具体步骤：1)、基坑降水：基坑开挖前先进行降水井施工，采用隔降排相结合的方式；2)、基坑开挖：采用明挖法进行基坑开挖施工，其中，纵向按预设的长度逐段开挖，横向分层、分段开挖；3)、基坑支撑：包括混凝土支撑及钢支撑；4)、施工监测：包括基坑围护结构体系监测、周边环境监测及现场巡视观察。本发明中，基坑降水采用隔降排相结合的方式，基坑内设置疏干井降水，保证降水井的施工质量；进而保证基坑施工的干作业面；基坑支撑采用混凝土支撑及钢支撑，保证基坑支撑体系的及时稳固；施工监测配合信息化监测技术，达到优质安全、经济合理的目的。
