Waterproof anti-seepage foundation pit steel cofferdam
The invention discloses a waterproof anti-seepage foundation pit steel cofferdam which comprises a plurality of steel pipe piles connected end to end, and each steel pipe pile comprises a steel pipe pile body internally provided with a pouring space; the notch structure comprises a pair of male notches and a pair of female notches; the lock opening structure comprises a male lock head and a female lock head, the male lock head comprises a first extension plate, a first fixing shaft, a male lock block and a male lock pin, and the female lock head comprises a second extension plate, a second fixing shaft, a female lock plate and a female lock pin. According to the method, pile gaps caused in the piling process can be reduced, the use amount of waterproof concrete is reduced, the good waterproof and anti-seepage effects are achieved, and the construction efficiency is improved.
本发明公开了一种防水抗渗基坑钢围堰，包括若干个首尾连接的钢管桩，所述钢管桩包括：钢管桩本体，其内部具有浇筑空间；槽口结构，其包括一对公槽口和一对母槽口；锁口结构，其包括公锁头和母锁头，所述公锁头包括第一延伸板、第一固定轴、公锁块、公锁销，所述母锁头包括第二延伸板、第二固定轴、母锁板、母锁销。本发明能够减小打桩过程造成的桩间隙，降低防水混凝土的使用量，具有良好的防水抗渗效果，提高了施工效率。
