Double-wall steel-concrete combined hanging box cofferdam construction method for pier bearing platform construction
The invention relates to the technical field of cofferdam construction, and provides a pier bearing platform construction double-wall steel-concrete combined hanging box cofferdam construction method which comprises the following steps: S1, forming a mounting hole in each steel casing; s2, a sliding driving mechanism is erected in the steel casing; s3, the supporting beam is arranged in the steel casing in a penetrating mode through the mounting hole; s4, the prefabricated concrete planks are arranged in the steel pile casings in a sleeving mode and are in lap joint with the ends of the supporting beams; s5, a post-cast strip between every two adjacent prefabricated concrete slabs is poured; s6, splicing steel wall plates around the periphery of the bottom plate to form a steel hanging box; s7, a hoisting system is erected at the top end of the steel casing; s8, the cofferdam structure is hoisted, wherein the bottom plate and the steel hoisting box are hoisted through a hoisting system; s9, the middle section of the supporting beam is cut off and moved out; s10, the two outwards-extending sections of the supporting beam are moved into the steel casing and moved out; and S11, the cofferdam structure is hoisted to the designed standard depth through the hoisting system. The method has the effect that the supporting beam on the steel casing is convenient to dismantle.
本申请涉及围堰施工的技术领域，提出了一种桥墩承台施工双壁钢混组合吊箱围堰施工方法，包括以下步骤：S1：在每处钢护筒上开设安装孔；S2：在钢护筒内支设滑移驱动机构；S3：将支撑梁通过安装孔穿设于钢护筒；S4：将预制混凝土板套入钢护筒并搭接支撑梁端部；S5：浇筑相邻预制混凝土板间的后浇带；S6：环绕底板外周拼接钢壁板，以形成钢吊箱；S7：在钢护筒顶端支设吊装系统；S8：围堰结构起吊：通过吊装系统将底板连同钢吊箱吊起；S9：将支撑梁的中间段切除并移出；S10：将支撑梁的两处外伸段移入至钢护筒并移出；S11：通过吊装系统将围堰结构吊放至设计标深。本申请具有便于钢护筒上支撑梁拆除的效果。
