Fabricated temporary cofferdam structure and installation and construction method
The invention relates to the technical field of steel sheet pile cofferdams, in particular to an assembly type temporary cofferdam structure and a mounting construction method.The cofferdam structure is arranged between side slopes on the two sides of a river channel and comprises assembled steel sheet piles and T-shaped structural connecting pieces, and a plurality of steel waist beam mounting pieces are mounted on the outer sides of the steel sheet piles between the side slopes on the two sides in an equidistant array mode; i-shaped steel waist beams are fixedly mounted between the tops of the steel waist beam mounting pieces; the T-shaped structure connecting pieces and the steel sheet piles are installed in a matched mode, a flood discharge area capable of being rapidly detached is formed in the middle of the cofferdam, the middle area of the cofferdam is backfilled through the sandy soil bags, water is blocked, the cofferdam structure is stabilized, meanwhile, rapid excavation is facilitated, and other areas of the cofferdam are backfilled through clay, so that the construction efficiency is improved. The impact resistance effect during flood discharge is improved while the cofferdam structure is stabilized, and the problem that the cofferdam function is lost during flood discharge is further avoided.
本发明涉及钢板桩围堰技术领域，尤其涉及一种装配式临时围堰结构及安装施工方法，围堰结构设置在河道两侧的边坡之间，包括装配而成的钢板桩和T型构造连接件，两侧边坡之间位于钢板桩的外侧等距阵列安装有多个钢腰梁安装件，各钢腰梁安装件的顶部之间固定安装有工型钢腰梁；本发明通过设置的T型构造连接件与钢板桩进行配合安装，实现在围堰中部形成可快速拆卸的行洪区域，在围堰中部区域通过沙土袋回填，实现挡水与稳定围堰结构的同时利于快速挖除，在围堰其它区域通过粘土回填，实现稳定围堰结构的同时增加在行洪时的抗冲击力效果，进一步的避免在行洪时出现围堰功能丧失的问题。
