Problems solved by technology

[0002] During mine construction, sometimes the surrounding rock of the roadway bursts suddenly and water gushes out. The rock fissures are large, and the water inflow exceeds the drainage capacity, so that the roadway is submerged. If the method of ground drilling and grouting is adopted, the cost will be huge

Abstract

The invention discloses a cereal injection device and a cereal injection method. The cereal injection device comprises a grouting pipeline, wherein the grouting pipeline comprises a first interface and a second interface, the first interface communicates with a grouting drill hole, the second interface communicates with a grouting pump, a first gate valve, a second gate valve and a third gate valve are arranged on the grouting pipeline, the first gate valve is arranged at one side of the first interface, the second gate valve is arranged at one side of the second interface, the third gate valve is arranged between the first gate valve and the second gate valve, and the first gate valve is used for loading cereal in a cereal pipeline. The cereal injection device is simple in structure, andcereal injection and grouting can be achieved by the grouting pipeline and a plurality of gate valves; a plurality of branch pipelines are alternatively used for performing cereal injection and grouting, continuous operation can be achieved, the loaded cereal is continuously and constantly sent into the drill hole, the grouting efficiency is greatly improved, and the grouting time is shortened.

Description

technical field [0001] The invention belongs to the technical field of grouting and water blocking, and in particular relates to a grain injection device and a grain injection method. Background technique [0002] During mine construction, sometimes the surrounding rock of the roadway bursts suddenly and water gushes out. The rock fissures are large, and the water inflow exceeds the drainage capacity, so that the roadway is submerged. If the method of ground drilling and grouting is adopted, the cost will be huge. [0003] At this time, drill holes can be arranged for the water outlet position from the upper part or near the non-submerged roadway, so that the drill holes can communicate with the water outlet cracks, and then the water can be blocked by grouting through the drill holes. However, due to the large cracks, the injected cement slurry will be all If it flows out, it will not be able to block the effect. At this time, it is necessary to inject grains of different p...
