Abstract

A grouting, water-stopping and water-blocking integrated device, including an anchor rod, the anchor rod is provided with a central hole passing through both ends, the pipe wall of the anchor rod is provided with side holes, and the outer circumference of the anchor rod is provided with a destructible protective shell, A pouch made of elastic material is arranged inside the protective shell, and the pouch cavity of the pouch communicates with the central hole of the anchor rod through the side hole. The all-in-one device for grouting, water-stopping and water-blocking of the present invention is provided with a capsule bag, if encountering the situation that the anchor bit drills into the groundwater layer, inject cement into the central hole immediately, the cement flows into the capsule cavity of the capsule bag from the side hole, and the capsule When the bag expands, the protective shell will be broken, and the expanded bag will block the drill hole, which can quickly block the water and improve the water blocking effect. Since the cement will not flow out of the bag, a large amount of cement can be saved.

Description

technical field

[0001] The invention relates to the technical field of mining equipment, in particular to a grouting, water-stopping and water-blocking integrated device. Background technique

[0002] Anchor bits play a vital role in the excavation process of mines, railway tunnels and hydropower departments. In the process of drilling rock bolts into rock formations, sometimes the anchor bit drills into the groundwater layer. Once the anchor bit The rod bit drills into the groundwater layer. Due to the large water storage capacity and high water pressure in the groundwater layer, if the cement is directly injected into the borehole, the cement is easily washed away by water and is not easy to form accumulations. The large amount of cement is used and the water blocking effect is poor. Contents of the invention

[0003] In order to solve the above-mentioned technical problem, the present invention proposes a grouting, water-stopping and water-blocking integrated device. ...
