Steel sheet pile and steel sheet pile support secondary disease control construction method
The invention discloses a steel sheet pile and a steel sheet pile support secondary disease prevention and control construction method, and relates to the field of deep foundation pit construction adopting steel sheet piles for supporting. The steel sheet pile comprises a main steel sheet, a sand injection pipe and a water injection pipe, and the sand injection pipe and the water injection pipe are arranged on the inner side face of the main steel sheet and arranged in the length direction of the main steel sheet; a mixing chamber is arranged on the inner side face of the main steel plate and located on the lower portion of the main steel plate, the lower ends of the sand injection pipe and the water injection pipe communicate with the mixing chamber, and the mixing chamber is provided with a discharging port for discharging water and sand after being mixed and a non-return assembly capable of controlling the discharging port to be opened or closed. According to the method, the phenomena of ground subsidence and displacement caused after pile pulling can be effectively restrained, safe and normal use of buildings (structures), underground pipelines and other municipal facilities around a foundation pit is guaranteed, and particularly secondary diseases such as large deformation and uneven subsidence caused by steel sheet pile supporting adopted in deep groove excavation under poor geological conditions can be solved.
一种钢板桩及钢板桩支护次生病害防治施工方法，涉及采用钢板桩进行支护的深基坑施工领域，该钢板桩包括主体钢板以及设置在主体钢板内侧面的注砂管和注水管，注砂管和注水管均沿主体钢板的长度方向设置，主体钢板的内侧面并位于其下部设置有混合室，注砂管和注水管的下端均与混合室连通，混合室具有供水、砂混合后排出的出料口以及能够控制出料口打开或关闭的止逆组件。本发明可有效抑制拔桩后引起的地面沉降和位移现象，保证基坑周围的建(构)筑物、地下管线和其他市政设施的安全和正常使用，尤其能够解决较差地质条件下深沟槽开挖采用钢板桩支护引起的较大变形和不均匀沉降等次生病害。
