Construction method of U-shaped steel sheet piles and steel pipe supporting structure in foundation pit
The invention relates to a construction method of U-shaped steel sheet piles and a steel pipe supporting structure in a foundation pit. The construction method comprises the following steps that a double-shaft deep mixing pile waterproof curtain is arranged in the foundation pit according to drawing requirements, and a dewatering tube well is excavated; the plurality of U-shaped steel sheet pilesare piled into the foundation pit according to preset positions; after piling of the U-shaped steel sheet piles is completed, a gradienter is adopted to carry out elevation treatment on the U-shaped steel sheet piles, and the steel pipe supporting structure is arranged at an elevation position; earth in the foundation pit is excavated in a layered mode, and a force transmission belt is arranged inthe foundation pit; after the steel pipe supporting structure is dismantled, concrete is poured into the foundation pit; and the earth is backfilled, and the U-shaped steel sheet piles are pulled out. The waterproof curtain, the U-shaped steel sheet piles and the steel pipe supporting structure are arranged in the foundation pit, so that the effects that construction safety in the foundation pitand short construction period are ensured are achieved, and convenience and rapidness are achieved; and meanwhile, the U-shaped steel sheet piles and the steel pipe supporting structure can be recovered and repeatedly used so that resources and engineering cost can be saved.
本申请涉及一种基坑内U型钢板桩及钢管支撑结构的施工方法，包括：根据图纸要求，在基坑内设置双轴深搅桩止水帷幕，并挖设有降水管井；将若干根U型钢板桩按照预设位置打桩至所述基坑内；U型钢板桩打桩完毕后，采用水平仪对所述U型钢板桩进行标高处理，并在标高位置处安装钢管支撑结构；对所述基坑内的土方进行分层开挖，并在所述基坑内设置传力带；拆除所述钢管支撑结构后，在所述基坑内浇筑混凝土；回填土方，并拔除所述U型钢板桩。通过在基坑内设置有止水帷幕、U型钢板桩及钢管支撑结构，达到保证基坑内施工安全、且施工周期短的效果，方便快捷；同时，U型钢板桩及钢管支撑结构能够可回收、多次周转使用，可以节省资源及工程成本。
