Steel sheet pile cofferdam structure supporting method
The invention relates to the field of building construction, in particular to a steel sheet pile cofferdam structure supporting method which comprises the steps that S1, a pipeline well and pipelines are designed and arranged, steel sheet piles are inserted and driven through an excavator with a hydraulic vibration hammer according to the design layout, or guide holes are constructed in the positions where the steel sheet piles are inserted and driven through a rotary drilling rig, and the steel sheet piles are inserted and driven in the guide holes; after construction of the steel sheet pile is completed, the detachable corbel bracket is installed; s2, the steel enclosing purlins and the detachable corbel brackets are correspondingly installed; s3, foundation pits are excavated on the inner sides of the steel enclosing purlins in a layered and segmented mode, adjustable diagonal bracing pieces are correspondingly installed in the steel enclosing purlins or/and the foundation pits, inner supports are excavated and installed in the foundation pits along with construction in a layered mode, and foundation pit backfilling is conducted; and S4, the adjustable diagonal bracing pieces and the steel enclosing purlins are sequentially dismantled, the steel sheet piles are pulled out, and grouting operation is conducted on the pile holes. The device is very efficient and quick to assemble and disassemble, support assembly and adjustment and opposite support length adjustment in the installation process can be carried out, the construction safety and the construction efficiency are improved, and the construction cost is saved.
本发明涉及建筑施工领域，具体公开了一种钢板桩围堰结构支护方法，其方法包括：S1、管线井及管线设计与布设，通过挖机带液压振动锤按设计布局插打钢板桩或在插打钢板桩位置旋挖钻机施工引孔并在引孔内插打钢板桩；钢板桩施工完毕后，安装可拆卸牛腿托架；S2、将钢围檩与可拆卸牛腿托架对应安装；S3、在钢围檩内侧按照分层、分段开挖基坑，在钢围檩或/和基坑中对应安装可调对撑件，基坑内部随施工分层开挖安装内支撑，进行基坑回填；S4、依次拆除可调对撑件、钢围檩，拔除钢板桩并对桩孔进行注浆作业。本发明装拆卸均非常高效快捷，也能进行安装过程中的支护装配、调节以及对撑长度调节，提高了施工安全性和施工效率，节约了施工成本。
