Construction method for steel sheet pile cofferdam of shallow covering layer deep and thick hard bed rock deepwater foundation pit
The invention relates to the technical field of bridge construction, and discloses a construction method for a shallow covering layer deep and thick hard bed rock deepwater foundation pit steel sheet pile cofferdam, which comprises the following steps: S1, building a construction platform on the water surface: the construction platform comprises an outer construction platform and an inner construction platform, a gap exists between the outer construction platform and the inner construction platform, and a reserved notch used for constructing the steel sheet pile cofferdam is formed. S2, pile hole and slotted hole construction is synchronously carried out; S3, concrete pile foundation and steel sheet pile cofferdam construction is synchronously carried out; s4, grouting to fix the steel sheet pile cofferdam; s5, a hanging bracket system is built on the outer construction platform, and a steel sheet pile cofferdam inner support is built on the inner construction platform; and S6, pumping water, excavating a rock stratum in the steel sheet pile cofferdam, and then hoisting an inner support of the steel sheet pile cofferdam. The construction method has the effect of improving the construction efficiency of the steel sheet pile cofferdam.
本申请涉及桥梁施工的技术领域，公开了用于浅覆盖层深厚硬基岩深水基坑钢板桩围堰的施工方法，包括：S1、在水面上搭建施工平台：所述施工平台包括外施工平台、内施工平台，所述外施工平台与内施工平台之间存在间距并形成用于施工钢板桩围堰的预留槽口；S2、同步进行桩孔及槽孔施工：S3、同步进行混凝土桩基和钢板桩围堰施工；S4、压浆以固定钢板桩围堰；S5、在外施工平台上搭建吊架系统，在内施工平台上搭建钢板桩围堰内支撑；S6、抽水并开挖钢板桩围堰内部岩层，然后吊装钢板桩围堰内支撑。本申请具有提高钢板桩围堰施工效率的效果。
