Foundation pit earth excavation construction method
The invention discloses a foundation pit earthwork excavation construction method, which relates to the technical field of building construction and comprises the following steps of 1, foundation pit zoning and sectioning, 2, earthwork layering, 3, foundation pit dewatering and drainage, 4, earthwork access channel determination, 5, earthwork excavation, 6, pile cutting, 7, concrete cushion maintenance and 8, foundation pit acceptance inspection. According to the construction method, 30 cm of foundation soil is reserved after earthwork machinery excavation, manual earth cutting is adopted, a concrete cushion layer is poured in time after the earthwork is repaired to the designed elevation, and an adjacent earthwork access channel is selected for earthwork excavation, and the construction method is provided that when each area and each layer of earthwork are excavated, 30 cm of foundation soil is reserved after earthwork machinery excavation, manual earth cutting is adopted, and the earthwork is excavated by the earthwork machinery; the excavation precision can be improved through manual excavation of reserved base soil, in addition, the small excavator is adopted around the pile foundation to be matched with manual excavation, the conditions of excessive excavation and pile body breakage can be effectively avoided, and the influence on the stability and safety of the foundation pit is avoided.
本专利公开了一种基坑土方开挖施工方法，涉及建筑施工技术领域，包括如下步骤，1基坑分区分段、2土方分层、3基坑降排水、4确定土方进出通道、5土方开挖、6截桩、7混凝土垫层养护、8基坑验收，步骤5中每个区域、每层土方开挖时，土方机械开挖后均留30cm基底土，采用人工挖土，修至设计标高后及时浇筑混凝土垫层，土方选取临近的土方进出通道进行出土，在本施工工法中提出，在每个区域、每层土方开挖时，土方机械开挖后均留30cm基底土，采用人工挖土，通过留置基底土人工挖掘，可以提高挖掘精度，另外在桩基周围采用小型挖掘机配合人工挖除，可以有效避免挖掘过度、挖断桩身的情况，避免影响到基坑的稳定性与安全性。
