Pre-buried box body sinking foundation pit supporting method
The invention relates to the technical field of building construction, in particular to an embedded box sinking foundation pit supporting method. Comprising the following steps: S1, designing and processing a pre-embedded box body structure; s2, measuring and setting out to determine the position of a secondary foundation pit, and pouring a cushion layer around the foundation pit; s3, shallow soil is excavated in the foundation pit, a flow guide groove is reserved, and a water collecting pit is excavated in the center; s4, the embedded box body is hoisted and placed; s5, a box body jet flow system is opened, and the box body slowly sinks under the gravity and pressure; s6, a slurry pump is placed at the water collecting pool to pump and discharge slurry to a slurry pool; s7, the embedded box body sinks to the designed position; s8, mortar is recharged into gaps in the outer side of the pre-buried box body; s9, excavating earthwork to a designed position in a layered manner; and S10, a subsequent structure is constructed. The embedded box body is reasonable in structural design, low in cost and easy to operate. The method is mainly applied to the aspect of embedded box body sinking foundation pit supporting.
本发明涉及建筑施工技术领域，更具体而言，涉及一种预埋箱体下沉基坑支护方法。包括以下步骤：S1、设计加工预埋箱体结构；S2、测量放样确定二次基坑位置，基坑周边浇筑垫层；S3、基坑内开挖浅层土，留设导流沟槽，中心开挖集水坑；S4、吊放预埋箱体；S5、打开箱体喷流系统，箱体在重力和压力下缓慢下沉；S6、集水池处放置泥浆泵抽排泥浆至泥浆池；S7、预埋箱体下沉至设计位置后；S8、预埋箱体外侧缝隙回灌砂浆；S9、分层开挖土方至设计位置；S10、施作后续结构。预埋箱体结构设计合理，成本较低，操作简单。本发明主要应用于预埋箱体下沉基坑支护方面。
