Underwater concrete pouring device in steel pipe and concrete pouring method
The invention provides an underwater concrete pouring device in a steel pipe and a concrete pouring method, and belongs to the field of concrete pouring. The underwater concrete pouring device is usedfor underwater concrete pouring of the steel pipe of a deep water lock catch steel pipe pile cofferdam and comprises a container pipe and a blocking part. A reduced concrete outlet is formed in one end of the container pipe. The blocking part comprises a conical plate, the conical plate is provided with a small end face and a large end face which are oppositely arranged, and the small end face ofthe conical plate faces the concrete outlet and is used for blocking the concrete outlet. The small end face is further fixedly provided with a steel bar stretching out of the concrete outlet. By means of the underwater concrete pouring method in the steel pipe, the problem that an existing conventional underwater concrete pouring process cannot be suitable for concrete pouring in the small-aperture steel pipe pile of the deep water lock catch steel pipe pile cofferdam can be solved. The underwater concrete pouring device in the steel pipe is simple in structure, easy to machine, convenient to construct and operate and reliable in pouring quality, and the problem that the conventional process cannot be suitable for underwater concrete pouring is ingeniously solved.
本发明提供了一种钢管内水下混凝土灌注装置及混凝土灌注方法，属于混凝土灌注领域，用于深水锁扣钢管桩围堰的钢管内水下混凝土灌注，包括容器管和堵塞件；容器管的一端形成缩口的混凝土出口；堵塞件包括锥形板，锥形板具有相对设置的小面端和大面端，锥形板的小面端朝向混凝土出口用于堵塞混凝土出口；小面端还固定设置有伸出混凝土出口的钢棒。通过本发明提供的钢管内水下混凝土灌注方法，能够解决现有常规水下混凝土灌注工艺不能适用于深水锁扣钢管桩围堰小口径钢管桩内混凝土灌注的问题。其中钢管内水下混凝土灌注装置结构简单且易于加工，施工操作方便，灌注质量可靠，巧妙解决常规工艺灌注水下混凝土不能适用的问题。
