Underground gushing water borehole aggregate addition system and process thereof

Abstract

The invention relates to an underground gushing water aggregate addition system and a process thereof. In the invention, aggregate can be smoothly and continuously injected into a borehole under the high-pressure gushing water condition to block up bigger guide water-contained fractures or overflow structures so as to drag the flow rate of gushing water, promote the materials to be settled and solidified and reduce the material loss, thereby achieving the goal of grouting to plug the water. The system comprises a grouting pipe. The grouting pipe is respectively communicated with a grouting casing pipe through a water injection pipeline I and a water injection pipeline II; the grouting casing pipe is provided with a sluice valve I and a sluice valve II; the joints of the water injection pipeline I and the grouting casing pipe are at the front end of the grouting casing pipe and the front part of the sluice valve I, and the joints of the water injection pipeline II and the grouting casing pipe are arranged between the sluice valve I and the sluice valve II, i.e. the water injection pipeline I and the water injection pipeline II are divided into two independent water injection systems through the sluice valve I.

Description

technical field [0001] The invention relates to an underground water gushing drilling aggregate adding system and a process thereof, belonging to the fields of grouting and water blocking in mines, transportation, water conservancy and the like. Background technique [0002] At present, after drilling underground mines, traffic tunnels, water conservancy projects, etc. to expose large water-conducting karst fissures, when high-pressure water inrush occurs, due to the high pressure, the water inflow is large, and the water-conducting structure or the water-passing channel is far away from the water discharge. When the point is short, it is difficult to realize the retention of the grouting material, causing a large amount of grouting material to burst out and be wasted in vain. The current method to deal with this problem is mainly to use organic polymer chemical grouting materials, which can only solve the superficial water gushing on the surface. And the cost is higher, an...

Problems solved by technology

[0002] At present, after drilling underground mines, traffic tunnels, water conservancy projects, etc. to expose large water-conducting karst fissures, when high-pressure water inrush occurs, due to the high pressure, the water inflow is large, and the water-conducting structure or the water-passing channel is far away from the water discharge. When the point is short, it is difficult to realize the retention of the grouting material, resulting in a large amount of grouting material collapsing and wasting in vain

The current method to deal with this problem is mainly to use organic polymer chemical grouting materials, which can only solve the superficial layer of water gushing

Moreover, the cost is high and the operation is difficult

According to the ground grouting process, due to the existence of high-pressure water gushing in the borehole, it is difficult to inject the water-blocking material into the borehole smoothly

When encountering such problems, it is often helpless to
