Background

In the construction operation of water conservancy and hydropower engineering, cement grout with different water-cement ratios is required to be designed and prepared according to different operation working conditions, cement thick grout is prepared by adopting fixed water and cement, and then water with corresponding ratio is prepared according to different operation requirements to prepare the cement grout with construction requirements.

In the grouting process of hydropower and hydraulic engineering, the water-cement ratio of cement grout (each grade of water-cement ratio corresponds to a density value) needs to be changed in time according to the injection rate (unit: L/min) of the cement grout, the change of grouting pressure, the injection time and the grout injection amount (unit: L). On the grouting working face, the upper layer barrel of the double-layer grouting barrel is generally adopted for preparing the grout. The pipeline for conveying the primary pulp (the water-cement ratio is about 0.5: 1) in the centralized pulping station is placed into the upper barrel of the double-layer grouting barrel, a certain amount of primary pulp is placed into the upper barrel, then the water with the corresponding proportion is placed into the upper barrel from the water pipeline, and the primary pulp and the water are mixed to form the required new pulp. The addition of the primary pulp and the water is discontinuous, and the addition can be controlled by adopting a weighing mode. The amount of the prepared grout is usually more (such as one barrel of grout or half barrel of grout) in each time of filling the barrel, so that the time for preparing new grout and changing the specific level of grout is delayed, and at the end stage of grouting, a barrel of grout or half barrel of grout prepared may be remained for a long time and is wasted.
