Fabricated deep foundation pit supporting structure and supporting method
The invention discloses a fabricated deep foundation pit supporting structure and a supporting method. The supporting structure comprises prefabricated columns and prefabricated walls, the prefabricated columns are arranged at intervals, the prefabricated walls are located between every two adjacent prefabricated columns, placement grooves are formed in the prefabricated columns, the side portions of the prefabricated walls are located in the placement grooves, cable cavities are formed in the prefabricated columns, anchor cables are arranged in the cable cavities in a penetrating mode, one ends of the anchor cables are connected with the prefabricated columns, and the other ends of the anchor cables are anchored in soil. The supporting method comprises the following steps: measuring and positioning; drilling holes by a drilling machine; prefabricated columns are arranged; digging a guide ditch; prefabricated walls are arranged; earth excavation is conducted; anchor cable construction; solidifying the anchor cable; and the operation is repeated until the designed depth is excavated. The construction method has the beneficial effects that the prefabricated columns and the prefabricated walls are used for supporting operation, components are prefabricated in a factory, field operation is convenient, the strength of the components is high, and the high-strength supporting requirement is met; the number of connecting nodes is small, grouting treatment can be carried out, an overall waterproof acting face is formed, and the waterproof and water blocking effects of the support are guaranteed.
本申请公开了一种装配式深基坑支护结构及支护方法。该支护结构包括预制柱和预制墙，预制柱间隔布置，预制墙位于相邻两预制柱之间，预制柱上设有安置槽，预制墙的侧部位于安置槽内，预制柱上设有索腔，索腔内穿设有锚索，锚索的一端与预制柱连接，锚索的另一端锚固在土体内。该支护方法包括如下步骤：测量定位；钻机成孔；安置预制柱；导沟开挖；安置预制墙；土方开挖；锚索施工；锚索固结；重复直至开挖至设计深度。本申请的有益效果：利用预制柱及预制墙进行支护作业，构件采用工厂预制，现场作业方便，构件强度高，满足高强度支护需求；连接节点较少，并且可以进行注浆处理，形成整体的防水作用面，保证支护的防水、阻水效果。
