Cofferdam device for floating pebble stratum and construction method of cofferdam device
The invention belongs to the technical field of bridge construction, and particularly relates to a floating pebble stratum cofferdam device and a construction method thereof. When cofferdam construction is carried out in a floating pebble stratum, steel sheet piles and steel jacket boxes cannot efficiently reach mounting positions, so that the construction process is complex, and the construction efficiency is low. According to the floating pebble stratum cofferdam device and the construction method of the floating pebble stratum cofferdam device, due to the fact that the construction method that the cofferdam is placed in the foundation trench is adopted during cofferdam construction, the cofferdam can reach the installation position easily, and the problem that the floating pebble stratum is prone to cracking and collapsing in the construction process to cause construction accidents is solved; excavated soil and stones can be repeatedly used for backfilling after being screened, and a good supporting effect is achieved. No matter the cofferdam is constructed by adopting a steel sheet pile or a steel jacket box, the cofferdam shows better structural stability. The device is simple in structure, the construction period is shortened, the construction efficiency is improved, and good economical efficiency is achieved; cofferdam construction in the pebble stratum is facilitated, and the method is suitable for popularization and application in the industry.
本申请属于桥梁施工技术领域，尤其涉及一种漂卵石地层围堰装置及其施工方法。在漂卵石地层中进行围堰施工时，钢板桩和钢套箱均无法高效地抵达安装位置，导致施工工序复杂，施工效率较低。本申请的漂卵石地层围堰装置及其施工方法，由于在围堰施工时，采用围堰安放基槽的施工方法，有利于围堰抵达安装位置，避免了漂卵石地层在施工中容易开裂与塌陷导致施工事故的问题；开挖后的土石经筛选后可重复利用进行回填，起到了良好的支撑作用。无论围堰采用钢板桩或者钢套箱施工，均表现出较好的结构稳定性。本申请的装置结构简单，缩短了施工周期，提高了施工效率，具有较好的经济性；有利于在漂卵石地层中进行围堰施工，适于行业内推广应用。
