Block enclosure isolation method for foundation pit supporting earth excavation
The invention provides a blocking enclosure isolation method for foundation pit supporting earth excavation, and belongs to the technical field of foundation pit excavation. The problems that an existing foundation pit is large in deformation and high in cost are solved. A row of first fender posts are poured on the circumferential edge of the large foundation pit, a first crown beam is poured on the tops of the row of first fender posts, and the blocking enclosure isolation method comprises the following steps that firstly, a row of second fender posts capable of being pulled out are inserted, and a second crown beam is arranged on the tops of the row of second fender posts; 2, the first fender post, the first crown beam, the supporting rod piece, the second crown beam and the second fender post form a whole through the supporting rod piece between the first crown beam and the second crown beam; 3, a small foundation pit is dug out, a bottom plate is poured at the bottom of the small foundation pit, and a force transmission belt is laid at the bottom of the small foundation pit; 4, an inclined foundation pit is dug out; and 5, the supporting rod pieces are dismantled, and the second top beam and all the second fender posts are pulled out. The blocking enclosure isolation method has the advantages that deformation of the foundation pit is reduced, and the construction cost is reduced.
本发明提供了一种用于基坑支护土方开挖的分块围护隔离法，属于基坑开挖技术领域。它解决了现有基坑变形大和成本高的问题。本大基坑周向边沿处浇筑一排第一围护桩，在一排第一围护桩的顶部浇筑第一冠梁，本分块围护隔离法包括以下步骤：步骤1、插入一排可拔除的第二围护桩，在一排第二围护桩的顶部设置第二冠梁；步骤2、第一冠梁和第二冠梁之间的支撑杆件使第一围护桩、第一冠梁、支撑杆件、第二冠梁和第二围护桩形成整体；步骤3、挖出小基坑，并在小基坑的底部浇筑底板和铺传力带；步骤4、挖出一个斜基坑；步骤5、拆除支撑杆件，拔出第二冠梁和所有的第二围护桩。本分块围护隔离法具有减少基坑变形且降低施工成本的优点。
