Thin covering layer high-strength rock stratum steel sheet pile cofferdam deep-buried tie beam and construction method
The invention relates to a thin covering layer high-strength rock stratum steel sheet pile cofferdam deeply-buried tie beam and a construction method. The construction method comprises the following steps that a steel casing is immersed, and one end of a profile steel positioning frame is fixed to the steel casing; inserting and driving a steel sheet pile, and fixing one end of the profile steel positioning frame on the steel sheet pile; soil bodies on the inner sides of the steel sheet piles are excavated, steel enclosing purlins are constructed, and temporary supporting frames are arranged between the steel pile casings; constructing a bottom sealing cushion layer; and the concrete pouring movable construction platform is installed. The construction method has the beneficial effects that the steel sheet pile and the steel casing are adopted to form the steel casing auxiliary guide steel sheet pile guide hole punching structure which is used for construction of the cast-in-place pile, the steel sheet pile construction precision is improved through the profile steel positioning frame, meanwhile, the construction efficiency of a high-strength rock stratum is improved through rotary digging of the guide hole, the construction period is shortened, and the cost is saved; the steel sheet pile cofferdam is formed through the temporary supporting frames and the steel supports for construction, the structural stability of the steel supports is improved, and the safety of the construction process is guaranteed.
本发明涉及一种薄覆盖层高强岩层钢板桩围堰深埋系梁及施工方法，包括以下步骤：沉放钢护筒，将型钢定位架一端固定在钢护筒上；插打钢板桩，将型钢定位架的一端另固定在钢板桩上；开挖钢板桩内侧土体并施工钢围檩，在钢护筒之间设置临时支撑架；进行封底垫层施工；安装混凝土浇筑移动式施工平台。本发明的有益效果是：采用钢板桩和钢护筒形成钢护筒辅助导向钢板桩引孔打设结构，用于灌注桩的施工，通过型钢定位架提高了钢板桩施工精度，同时通过旋挖引孔提高了在高强岩层的施工效率节省了工期，节约了成本；通过临时支撑架和钢支撑形成钢板桩围堰进行施工，提高了钢支撑结构稳定性，保证了施工过程安全。
