Negative pressure elephant trunk concrete conveying method
The invention provides a negative pressure elephant trunk concrete conveying method, which is characterized in that a negative pressure elephant trunk concrete conveying system is arranged above a large-fall deep foundation pit structure of to-be-poured concrete, the system comprises a negative pressure vacuum pump, a collecting hopper, an elephant trunk, a chute, a flow velocity meter and a central control system, the upper end of the elephant trunk is hermetically connected with the negative pressure vacuum pump, and the lower end of the elephant trunk is hermetically connected with the collecting hopper; the lower end of the articulated chute is connected with one end of the chute, the top, close to the upper end, of the articulated chute is provided with an opening, the opening is connected with a discharging opening of the collecting hopper in a sealed mode, the discharging opening of the collecting hopper is provided with an electric opening and closing valve, and the flow velocity meter is arranged on the chute. Concrete flows into the articulated chute through the electric opening and closing valve under the action of gravity and then flows into the surface of the pouring bin after flowing through the chute, and the flow velocity of the concrete on the chute is measured in real time through the flow velocity meter; the central control system regulates and controls the concrete flow velocity according to the concrete flow velocity measured by the flow velocity meter, and the phenomena of segregation and pipe blockage caused by too high pouring speed due to the gravity action of concrete are avoided.
本发明提供一种负压溜管混凝土输送方法，通过在待浇筑混凝土的大落差深基坑结构上方布设负压溜管混凝土输送系统，该系统包括负压真空泵、集料斗、溜管、溜槽、流速仪及中央控制系统，溜管的上端与负压真空泵密封连接，溜管的下端与溜槽的一端连接，溜管上靠近上端的顶部开口并在开口处与集料斗的卸料口密封连接，集料斗的卸料口处设有一电动启闭阀门，流速仪设置于溜槽上，预拌混凝土在集料斗处集中，混凝土在重力作用下经过电动启闭阀门流入溜管，然后流经溜槽后流入浇筑仓面，通过流速仪实时测量溜槽上的混凝土流速；中央控制系统根据流速仪测得的混凝土流速调控混凝土流速，避免混凝土由于自身重力作用导致浇筑速度过快而发生离析、堵管现象。
