摘要
顺作法钢板桩围堰在目前的水利及路桥建设工程中使用较多。结合工程实践提出了深水逆作法钢板桩围堰综合成套技术,一定程度上解决了常规的顺作法钢板桩适用的水深较浅、围堰变形大、整体稳定性偏低、施工风险相对较高的缺点。详细介绍逆作法钢板桩围堰的设计、构造、分析以及施工工艺,并对实际工程施工过程中钢板桩围堰的受力及变形情况进行了监测。结果表明,该技术较好地满足了工程的经济性和安全性的要求。
The method of steel sheet pile cofferdam with sequential construction is broadly applied in many projects of road, bridge and hydraulic engineering. Comprehensive technology of steel sheet pile cofferdam with inverse construction technique in deep water is proposed, which could be used to conquer weaknesses of steel sheet pile cofferdam with sequential construction, such as large deformation, low global stability, high construction risk and restricted water depth. Design, analysis and construction of steel sheet pile cofferdam with conversable construction technique in deep water are given in detail, deformation and force situation of steel sheet pile cofferdam in the construction progress is monitored. The technique could preferably satisfy the requirement of safety and economy in engineering construction.
