Novel steel hanging box cofferdam manufacturing process based on Larsen steel sheet pile
The invention relates to a novel steel hanging box cofferdam manufacturing process based on a Larsen steel sheet pile. The novel steel hanging box cofferdam manufacturing process is characterized by comprising the following specific steps of S1, manufacturing of a steel bottom plate; S2, manufacturing of side plates; S3, manufacturing of hangers; S4, assembling of the steel bottom plate and lowerhanger units; S5, assembling of the hangers; S6, mounting of ring beam brackets; S7, assembling of the side plates; S8, primary bottom sealing and water pumping; and S9, secondary bottom sealing. According to the novel steel hanging box cofferdam manufacturing process, the structure of the Larsen steel sheet pile is adopted as a side edge module structure of a steel hanging box cofferdam, and sideedge modules of the structure are high in strength, light and good in water stopping performance; assembling and disassembling are easy; the turnover performance is high, the cost is low, the applicability to deep water is high, multiple internal supports are arranged, and the enough strength requirement is guaranteed; and in addition, a concrete structure is poured on a bottom plate module, compared with a bottom plate of a steel structure, the advantage of being low in economic cost is achieved, and the profile steel structure is easy to machine and assemble; machining is fast, and the period is short; and the applicability is high, and trepanning is easy.
本发明涉及一种基于拉森钢板桩的新型钢吊箱围堰制造工艺，其特征在于：具体工艺如下：S1：钢底板的制造；S2：侧板的制造；S3：吊挂的制造；S4：钢底板及下吊挂单元的拼装；S5：吊挂的拼装；S6：圈梁牛腿的安装；S7：侧板的拼装；S8：一次封底及抽水；S9：二次封底；本发明中采用拉森钢板桩的结构作为钢吊箱围堰的侧边模块结构，该结构的侧边模块高强度，轻型，止水性好；拼装，拆除简易；周转性高，成本低，对深水的适用性强且内部支撑多，保证了足够的强度要求；此外，在底板模块上浇筑混凝土结构，相比于钢结构的底板，就具有经济成本低的优点，且本发明的型钢结构易加工、易于拼装；加工快，周期短；适用性强，开孔容易。
