Description

A rapid plugging device for borehole pressurized water

technical field

The utility model belongs to the field of prevention and control of mine floods, in particular to a fast plugging device for pressurized water in boreholes.

Background technique

With the increasing number of underground projects such as mining projects and tunnel projects, roadway water inrush accidents occur from time to time, causing a large amount of economic losses. To the pressurized water layer, when the drill pipe is pulled out, the pressurized water will be sprayed out through the borehole, and the borehole must be blocked. In the past, this phenomenon occurred, usually by stacking sandbags, injecting concrete or using conical wood for sealing. These sealing methods are time-consuming, labor-intensive and uneconomical, and the sealing effect is relatively poor. Generally, subsequent sealing work is required. Fast and efficient plugging of boreholes is still a problem.

Contents of the invention

The purpose of this utility model is to provide a fast plugging device for borehole pressurized water according to the above-mentioned deficiencies in the prior art. The borehole is blocked by two sealing capsules up and down. The plugging effect is good and the structure is simple. , Easy to operate.

The realization of the purpose of the utility model is accomplished by the following technical solutions: a rapid plugging device for borehole pressurized water, including a grouting device and a plugging device, and the grouting device is used to provide quick-setting cement slurry to the plugging device , the plugging device is composed of a grouting pipe and a plugging capsule, the part of the grouting pipe connected to the plugging capsule is distributed with grouting holes, the top of the grouting pipe is connected with a claw block, and the plugging The capsule is divided into upper and lower two blocking capsules.

The above-mentioned rapid plugging device for borehole pressurized water is characterized in that the grouting pipe and the claw block are connected by a threaded connection pipe, and various types of claw blocks can be replaced at will to adapt to different borehole diameters and borehole lithology.

The above-mentioned rapid plugging device for borehole pressurized water is characterized in that the position of the grouting hole is offset by 90 degrees at the upper and lower two-stage sealing capsules, so as to achieve the control of the upper and lower two-stage sealing capsules by rotating the grouting pipe Effect of grouting order.

The above-mentioned rapid plugging device for pressurized water in boreholes is characterized in that a tray is fixed at both ends of the plugging capsule, which functions to fix the capsule and prevent the capsule from shifting after it is filled and expanded.

The utility model provides a fast-blocking device for borehole pressurized water, which injects quick-setting cement slurry into the plugging capsule to make the capsule expand and solidify to achieve the effect of sealing the pressurized water borehole. The difference from the prior art is that, on the one hand, the capsule is injected with quick-setting cement, which can permanently seal the water-inrush borehole after the cement solidifies. On the other hand, the upper and lower sections are used to seal the capsule, and the grouting time is separated, so that the sealing effect is better.

detailed description

The utility model shows a fast plugging device for borehole pressurized water. In order to make the advantages and technical solutions of the utility model clearer, the utility model is further clearly and completely described in conjunction with the following specific implementation methods.

As shown in Figure 1, a rapid plugging device for borehole pressurized water consists of a grouting device and a plugging device. The grouting device is used to provide quick-setting cement slurry to the plugging device. The plugging device is composed of The grouting pipe 6, the upper plugging capsule 1 and the lower plugging capsule 2 are composed of the grouting pipe 6 and the part where the upper plugging capsule 1 and the lower plugging capsule 2 are connected to distribute the grouting holes 4, and the top of the grouting pipe 6 passes through The threaded connecting pipe 7 is connected with the claw block 3, and the two ends of the upper blocking capsule 1 and the lower blocking capsule 2 are fixed with trays 9.

When in use, first select a suitable type of claw block 3 and connect it to the grouting pipe 6 through the threaded connection pipe 7, then put the plugging device as a whole into the drilled hole where the water inrushes, and use the claw block 3 at the top of the grouting pipe 6 to insert into the hole The surrounding rock of the wall is used as a fulcrum, and then the quick-setting cement slurry is put into the slurry storage tank 13, and the valves 14, 11, and 5 are opened in turn, and the cement slurry is injected into the plugging device through the grouting pump 10 through the pipeline 15. Observe the pressure gauge 12 to prevent the sealing capsule from being broken due to excessive pressure. The lower sealing capsule 2 is first grouted. After the lower sealing capsule 2 is filled with cement slurry and solidified, rotate the grouting pipe 90 degrees to the upper sealing capsule. The plugging capsule 1 is grouted until the upper plugging capsule is filled with cement slurry and then the valve 5 is closed. After the cement slurry in the upper plugging capsule 1 is completely solidified, the threaded joint is rotated to separate the grouting pipe 6 from the pipeline 15, and finally Clean the grouting pipeline and equipment for the next use.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of Changes or replacements should fall within the protection scope of the present utility model.
