Description

Technical Field

[0001] The utility model relates to the technical field of address exploration equipment, in particular to a grouting device used for exploring drilling holes in water-conducting fracture zones. Background Art

[0002] A commonly used method for sealing a borehole is grouting. A Chinese patent (CN210370586U) discloses a water-outlet elevation drilling grouting water-stopping device, which is provided with a casing two and a casing one sleeved on the outside of the casing two, the outer end of the casing one is sealed with the casing two, and grouting is injected into the gap between the casing two and the casing one, and between the casing two and the different-diameter hole body. When slurry flows out from the casing two, it means that the gap between the casing two and the casing one, and between the casing two and the different-diameter hole body has been filled with slurry. In this technology, the completion of the grouting operation is judged by the overflow of the slurry. This method has the problems of high grouting delay and untimely feedback during actual use. Moreover, since the hole body and the different-diameter hole body are in an elevation state, that is, both casing one and casing two are in an inclined state, there is a height difference between the two opposite sides of the upper port of casing two. When the slurry level rises to the height of the low end side of the upper port of casing two, the slurry can flow out of casing two. At this time, the part between the high and low end sides of the different-diameter hole body corresponding to the upper port of casing two is still not filled with slurry, that is, in fact, the gap between casing two and the different-diameter hole body is not yet filled with slurry. Therefore, the equipment cannot achieve the ideal design effect during grouting. Utility Model Content

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
