Pebble covering layer steel sheet pile cofferdam system and construction method thereof
The invention relates to a pebble covering layer steel sheet pile cofferdam system and a construction method thereof. The pebble covering layer steel sheet pile cofferdam system is suitable for a terrane geological structure provided with a pebble covering layer and comprises anchor rods, walings, inner supports, steel sheet piles, a bottom sealing concrete plate and concrete ring beams, the anchor rods are distributed along the periphery of a cofferdam area, and the lower ends of the anchor rods are anchored in a terrane; the walings surround the anchor rods; the inner supports support the walings; the steel sheet piles are tightly attached to the lower ends of the walings and inserted into the pebble covering layer; the bottom sealing concrete plate is flush with the anchoring sections of the anchor rods; and/or the concrete ring beams are arranged on the upper layers of the anchoring sections of the anchor rods. By the adoption of the technical scheme, the permeable rate is reduced, and the water stopping effect on the roots of the steel sheet piles is achieved; and meanwhile, the steel sheet piles form effective support under the condition of no built-in depth.
本发明涉及一种卵石覆盖层钢板桩围堰系统及其施工方法，适用于具有卵石覆盖层的岩层地质结构，包括沿围堰区域外周分布的下端锚固在岩层的锚杆、围合锚杆的围囹、支撑围囹的内支撑、紧贴围囹的下端插入卵石覆盖层的钢板桩，还包括与锚杆锚固段平齐的封底砼板或/和设置在锚杆锚固段上层的砼圈梁。通过采用上述技术方案，降低透水率，起到对钢板桩根部的止水效果；同时，钢板桩在无嵌固深度情况下形成有效支护。
