Description

Grouting water stop water plugging integrated device

technical field

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

Background technique

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

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

Technical scheme of the present invention is:

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.

Preferably, the pouch is a pouch made of rubber material.

Preferably, the outer circumferences near both ends of the anchor rod are provided with threads.

Preferably, a clamp is provided in the cavity of the bladder, and the clamp fixes the bladder wall close to the outer circumference of the anchor rod and the corresponding anchor rod together.

Preferably, stoppers are respectively fixed on the outer circumferences of the anchor rods at both ends of the protective shell.

Preferably, the anchor rod is provided with at least two bladder sets along the axial direction, and each bladder set includes a bladder, a protective shell arranged on the outside of the bladder, a clamp arranged in the cavity of the bladder and a Blocks at both ends of the protective case.

The beneficial effects of the present invention are:

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 water and improve the effect of water blocking. Since the cement will not flow out of the bag, a large amount of cement can be saved.

detailed description

Embodiment 1: Referring to Figure 1-2, a grouting, water-stopping and water-blocking integrated device includes an anchor rod 1, and the outer circumference of the anchor rod 1 near both ends is provided with threaded buckles 11, and the multi-section anchor rod 1 or the anchor rod 1 It is connected with the anchor drill bit by a screw thread 11. The anchor rod 1 is provided with a central hole 12 through both ends, the pipe wall of the anchor rod 1 is provided with side holes 13, the outer circumference of the anchor rod 1 is provided with a destructible protective shell 3, and the protective shell 3 is provided with a bag made of elastic material The bag 2 , the pouch 2 is a pouch made of rubber material, and the pouch chamber 21 of the pouch 2 communicates with the central hole 12 of the anchor rod 1 through the side hole 13 .

When the bolt is transported, assembled or used normally, the bag 2 is in a contracted state, and the protective shell 3 is used to protect the bag 2 from damage by external force. When the situation that the anchor drill bit drilled into the groundwater layer took place, cement was injected into the central hole 12 immediately, and the cement flowed into the bladder cavity 21 of the bladder 2 from the side hole 13, and the bladder 21 expanded and the protective shell 3 (protective shell 3 is a destructible thin layer), the expanded capsule 2 will block the borehole (as shown in Figure 2), and there is no need to use a grouting hole sealer to seal the borehole, which saves the water plugging reaction time and can Realize rapid water blocking and improve the water blocking effect; because the cement will not flow out of the bag, it can save a lot of cement and save costs.

Embodiment 2: Referring to FIG. 3 , Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a clip 6 is provided in the pouch cavity 21 of the pouch 2, and the clip 6 holds the pouch together. The bag 2 is fixed to the corresponding anchor rod 1 with the bag wall close to the outer circumference of the anchor rod. Blocking platforms 5 are respectively fixed on the outer circumference of the anchor rod 1 at both ends of the protective shell 3 .

The bladder 2 is fixed on the anchor rod 1 through the clamp 6, and the outer circumference of the anchor rod 1 at both ends of the protective shell 3 is respectively fixed with stoppers 5 to prevent the bladder 2 from sliding axially along the anchor rod 1 when the water pressure is high , to enhance the water blocking effect of the capsule bag 2.

Embodiment 3: Referring to Fig. 3, Embodiment 3 is basically the same as Embodiment 2, and the similarities will not be repeated. The difference is that the anchor rod 1 is provided with two bladder groups along the axial direction, and each bladder group is It includes a pouch 2 , a protective shell 3 arranged on the outside of the pouch 2 , a hoop 6 arranged in the cavity 21 of the pouch, and blocks 5 arranged at both ends of the protective casing 3 . The anchor rod 1 is provided with two bladder groups along the axial direction, forming two-stage waterproof layers, and improving the overall water blocking effect of the integrated grouting, water-stopping and water-blocking device.
