Problems solved by technology

For the downward blast hole, under the action of gravity, the blasthole mud can easily enter the blast hole, and the blast hole filling is relatively easy; but for the horizontal blast hole or the inclined upward blast hole, the conventional blast hole sealing technology, due to the irregular blast hole wall , not smooth, the blasting mud is easily stuck by the protrusion in the middle during the filling process and damaged, the blasting mud cannot be delivered to the designated position, there is a hollow inside, and the filling is not in place, which seriously affects the blasting effect
In addition, using this method to fill blastholes often takes a certain amount of time to consolidate the stuffing to a certain strength, and the plugging effect is affected by factors such as the properties of the plugging material, the consolidation time, and the operation method. and prone to waste pollution

Embodiment 1

[0046] Such as figure 1 and figure 2 As shown, a self-sealing orifice clamping device includes a self-sealing component and an orifice clamping component; the orifice clamping component includes a cylindrical hollow tube 3 .

[0047] Such as Figure 4 As shown, the hollow tube 3 is surrounded by a top plate, a bottom plate 8 and a side wall, and the conical pushing rod 7 inside and the external rotating block 2 are composed of three parts. The side wall of the cylindrical hollow tube 3 stretches out the wall claw 4, The top of the hollow cylinder 3 is flexibly connected with the external rotating block 2, and the bottom of the hollow cylinder 3 is connected with the self-sealing component.

[0048] Such as image 3 As shown, the outer rotating block 2 passes through the top plate of the cylindrical hollow tube 3 and is movable, the bottom center of the outer rotating block 2 has a threaded hole 12 deep inside, and the top of the outer rotating block 2 has a wrench 1 stretc...

Embodiment 2

[0062] A construction method of a self-sealing orifice clamping device, comprising the following steps:

[0063] According to the on-site blasthole diameter and blasthole wall material, calculation and on-site experiments are carried out. For example, the blasthole diameter is 110mm, and the hole wall material is granite. Then select the appropriate hollow cylinder 3 diameter, beef tendon rod length, and conical expansion part according to this condition. 14 positions, telescoping distance of the wall claw 4 and the length of the threaded part 13, etc. For example, in this example, the hollow cylinder 3 with a diameter of 100mm is selected, the original diameter of the wall claw 4 is 104mm, the maximum elongation diameter is 118mm, and the original diameter of the beef tendon rod is 100mm , the specific usage method includes the following steps:

[0064] Step 1: Put the self-sealing orifice clamping device into the blast hole, extend the wall claw 4 into the blast hole, and le...

Abstract

The invention provides a self-sealing orifice clamping device. The self-sealing orifice clamping device comprises a self-sealing component and an orifice clamping component. The orifice clamping component comprises a cylindrical hollow cylinder (3), a first through hole is formed in a top plate of the hollow cylinder (3), an external rotating block (2) is rotatably connected into the first throughhole, a threaded hole (12) penetrating into the external rotating block (2) is formed in the bottom end of the external rotating block (2), a pushing rod (7) is in threaded connection with the interior of the threaded hole (12), a third through hole is formed in a bottom plate (8) of the hollow cylinder (3), and a long straight rod part (9) penetrates through the third through hole and is fixedlyconnected with a supporting plate (10) of the self-sealing component. The invention further discloses a construction method of the self-sealing orifice clamping device. The mechanical self-sealing orifice clamping device is suitable for plugging various orifices, does not use other plugging materials (quick-setting cements and the like), can be repeatedly used, and is efficient in plugging, goodin sealing performance and convenient to operate.

Description

technical field [0001] The invention relates to a self-sealing orifice clamping device and a construction method thereof, and belongs to the technical field of blasting devices, blasting blast hole holes and blast hole plugging. Background technique [0002] Blasting is often required in municipal transportation projects such as mining and stone mining, excavation of foundation pits, construction of tunnels and underground spaces, safe blasting removal of stubborn rocks / solitary rocks, and dredging of pipelines and other blockages. The blasting fracturing method has the characteristics of high efficiency and low cost, and is widely used in rock mass excavation such as mining engineering, underground transportation engineering, and water conservancy and hydropower engineering. [0003] Blast hole plugging plays an important role in engineering blasting. Reasonable plugging can ensure that explosives fully react, make them release maximum heat and reduce toxic gas generation, ...
