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 grain injection device and a grain injection method. The grain injection device includes a grouting pipeline, and the grouting pipeline includes a first interface connected with a grouting hole and a first interface connected with a grouting pump. Two ports, the grouting pipeline is provided with a first gate valve on the side of the first port, a second gate valve on the side of the second port, and a third gate valve between the first gate valve and the second gate valve, the third gate valve Used to load grain into grain lines. The structure of the grain injection device of the present invention is simple, and the grain injection and grouting can be realized through the grouting pipeline and multiple gate valves; multiple branch pipelines alternately carry out grain injection and grouting, which can realize continuous operation, and the loaded grain can be continuously It is continuously fed into the borehole, which greatly improves the grouting efficiency and shortens the grouting time.

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...
