Problems solved by technology

[0002] High-angle roadways are common in all kinds of mines, such as inclined coal mines and uphill slopes in coal mines, strip stopes in non-coal mines, etc., because there may be safety hazards such as water gushing and gas outbursts in abandoned cutouts and wind tunnels, and cannot be used for Underground construction provides a safe construction environment, and it is difficult to install underground construction equipment and pipelines, so it needs to be grouted and filled
[0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. The backfilled solid matter is difficult to stay at the plugging point due to the excessive sliding force and slips away to a distance, making backfilling or sealing The amount of plugging is too large and the cost is too high; 2. It is easy to cause too much grout to spread, which makes the grouting volume too large, reducing its performance

Embodiment 1

[0034] See Figure 1 to Figure 4 , A column-type high-angle inclined lane drilling and grouting plugging equipment and method. The present invention provides a technical solution:

[0035] A column-type high-angle inclined tunnel drilling and grouting plugging equipment, such as figure 1 , figure 2 , image 3 versus Figure 4 As shown, it includes a roadway 8 and a grouting bag 7 located inside. A grouting pipe 3 penetrates through the inside of the grouting bag 7, and an anti-sliding column 6 is fixedly installed on the outer surface of the lower end of the grouting pipe 3. A drill pipe 2 is provided above the grouting pipe 3, a drill 1 is fixedly installed at the upper end of the drill pipe 2, and a strapping rope 9 is provided at the position where the bag mouth of the grouting bag 7 contacts the drill pipe 2. A bag separator is arranged between the drill pipe 2 and the grouting pipe 3. The bag separator has two forms: a pull-off shear pin 5 or a rotary anti-thread buckle. Th...

Embodiment 2

[0055] Embodiment The invention provides a column-type high-angle inclined road borehole grouting and blocking device and method, which are basically the same as Embodiment 1, and the difference lies in:

[0056] The described method for column-type high-angle slanting lane borehole grouting and plugging uses a rotating anti-threaded button to separate the bag body and the drill rod 2:

[0057] S2: Install the grouting bag 7. Before drilling, insert the grouting pipe 3 into the grouting bag 7, and wrap the grouting bag 7 around the grouting pipe 3 and tie it with the strapping rope 9 to ensure that the upper bag mouth is in the opposite direction. Under the threaded button, the lower bag mouth is located above the anti-slip column 6, the grouting pipe 3 is inserted into the grouting bag 7, and the grouting bag 7 is lowered into the roadway 8 to be blocked to ensure that the grouting pipe 3 enters the bottom drilling In the hole, connect the grouting pipe 3 to the drill pipe 2 with ...

Abstract

The invention discloses a stand column type high-angle inclined drift drilling, grouting and plugging device and method, and relates to the technical field of grouting and plugging. The stand column type high-angle inclined drift drilling, grouting and plugging device comprises a drift and a grouting bag positioned in the drift, wherein a grouting pipe is penetrated in the grouting bag; the outersurface of the lower end of the grouting pipe is fixedly provided with a slipping resistance column; a drill rod is arranged on the top of the grouting pipe; and the upper end of the drill rod is fixedly provided with a drilling machine. The stand column type high-angle inclined drift drilling, grouting and plugging method comprises the following steps of S1) determining the length of the groutingpipe and the height of the grouting bag; S2) installing the grouting bag; S3) carrying out grouting; and S4) carrying out repeated grouting. By use of the invention, a situation that a grouting amount is excessive because a backfilling or plugging workload is excessive and grout spreads too far since backfilled solid substances slip to a far place from a plugging point can be avoided, cost is saved, and the usability of the device is improved.

Description

Technical field [0001] The invention relates to the technical field of borehole grouting and blocking, in particular to a column type high-angle inclined road borehole grouting and blocking equipment and method. Background technique [0002] High-angle roadways are common roadways in all kinds of mines, such as coal-slipping inclined shafts and uphills in coal mines, and strip stopes in non-coal mines. Because abandoned open cuts and wind tunnels may have safety hazards such as water inrush and gas outburst, they cannot be Underground construction provides a safe construction environment, and it is difficult to install underground construction equipment and pipelines, so it needs to be filled with grouting. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. The backfilled solid material is difficult to stay at the plugging point due to excessive sliding force and slips to a fa...
