Underwater cofferdam structure and construction method thereof
According to the underwater cofferdam structure and the construction method thereof, the overall stability of a combined pile of a positioning steel pipe pile, a steel sheet pile and a reinforcing pile is adopted, all accumulated water in the cofferdam can be removed at a time after the cofferdam is integrally completed, and construction is guided by monitoring and measuring deformation of the cofferdam in the process, so that the construction procedure is simplified, and the construction efficiency is improved; and the construction time is shortened. According to the underwater cofferdam structure, through calculation of the construction stress of the cofferdam combined piles, the strength and rigidity of the combined piles are greatly improved compared with those of single steel sheet piles, the deformation resistance is improved, deformation is small according to calculation on the premise that the stress is not changed, the number of cofferdam supports is reduced, the interval height of the cofferdam supports is increased, the number of procedures is reduced, and time is shortened; the cost investment is reduced. The problems that construction of an existing steel sheet pile cofferdam is low in construction efficiency and complex in construction process, and the construction period is prolonged are solved.
本发明公开了一种水中围堰结构及其施工方法，采用定位钢管桩、钢板桩以及加固桩的组合桩整体稳定性，围堰整体完成后可以一次性排除围堰内全部积水，过程中监控量测围堰的变形指导施工，简化了施工工序，提高了施工效率，缩短了施工时间。本发明的水中围堰结构通过围堰组合桩施工受力计算，组合桩比单一钢板桩强度刚度都要增加很多，增了抗变形能力，根据计算在受力不变的前提下变形较小，减少围堰支撑的数量，加大围堰支撑的间隔高度，较少工序，缩短时间，减少成本投入。本发明解决了现有的钢板桩围堰的施工，存在施工效率较低，施工工艺复杂，增加了施工周期的问题。
