Concrete conveying device for open caisson construction
The invention relates to a concrete conveying device for open caisson construction. The conveying device comprises a conveying pipeline, wherein the conveying pipeline is sequentially connected with aflexible hose, an elbow pipe and a steel pipe from the concrete input direction to the concrete output direction, the steel pipe is inserted in the axial direction of an open caisson, the output endof the steel pipe is provided with a blocking device, and when concrete reaches 0.2 cubic meter, the blocking device is separated from the output end of the steel pipe, and the concrete falls into thebottom of an open caisson cavity. According to the concrete conveying device for open caisson construction, the steel pipe is adopted in the open caisson, due to the fact that the steel pipe has a certain weight, the buoyancy of underground water can be overcome, the blocking device is arranged at the output end of the bottom of the steel pipe to form a closed space, and when the concrete reaches0.2 cubic meter, the blocking device is separated from the output end of the steel pipe, the phenomenon that the concrete forming is influenced by the underground water flowing backward into a concrete conveying pipe is effectively prevented.
本发明涉及一种用于沉井施工的混凝土输送装置，输送装置包括：输送管路，其由混凝土输入方向至混凝土输出方向依次连接有柔性软管、弯头管及钢管；钢管沿沉井轴向方向插入；钢管输出端设置有阻隔装置，阻隔装置当混凝土达到0.2立方米时，其与钢管输出端分离，混凝土下落掉入沉井空腔底部。本发明公开提供了一种用于沉井施工的混凝土输送装置，沉井内采用钢管，由于钢管有一定重量可以克服地下水的浮力，并在其底部输出端设置有阻隔装置形成封闭的空间，当混凝土达到0.2立方米时，阻隔装置与钢管输出端分离，由此有效防止了地下水倒灌混凝土输送管影响混凝土成形的现象。
