Problems solved by technology

[0004] The current blasting tube fixing device is not ideal for use. During the explosion process, the blasting tube itself will be displaced, which will cause the blasting tube to pop out from the inside of the blasting hole, and the existing blasting tube fixing device cannot adapt to blasting tubes of different diameters. In actual use restricted

Embodiment 1

[0029] refer to Figure 1-4 As shown, this embodiment provides a blasting pipe fixing device for geotechnical blasting, including a mounting pipe 1, an adaptive outer fixing unit for fixed installation with a blasting hole, and an adaptive inner fixing unit for fixing the blasting pipe;

[0030] The adaptive outer fixing unit is installed outside the installation pipe 1 , and the adaptive inner fixing unit is installed inside the installation pipe 1 .

[0031] When in use, insert the blasting tube into the self-adaptive inner fixing unit, and the self-adaptive inner fixing unit adjusts adaptively according to the diameter of the blasting tube, clamps and fixes the blasting tube inside, so that the blasting tube cannot move, and the self-adaptive outer fixing unit is fixed. Tighten it to reduce its outer diameter, then insert the device into the blasting hole, and then release the self-adaptive external fixing unit to expand its outer diameter and press against the inner wall o...

Embodiment 2

[0041] refer to Figure 5 As shown, the difference between the blasting pipe fixing device for rock and soil blasting in this embodiment and the first embodiment is only that a flexible gasket 16 is fixedly installed on the inner side of the arc-shaped clamping sheet 7, and the flexible gasket 16 can be a rubber gasket, which is used for To protect the blasting tube and prevent the blasting tube from being scratched by inserting the arc-shaped clamping piece 7 of the blasting tube, the inner side of the flexible gasket 16 is provided with anti-skid lines to enhance the friction between the flexible gasket 16 and the blasting tube.

Abstract

The invention discloses a blast pipe fixing device for rock-soil blasting. The blast pipe fixing device comprises a mounting pipe, a self-adaptive outer fixing unit and a self-adaptive inner fixing unit, wherein the self-adaptive outer fixing unit and a blast hole are fixedly mounted; the self-adaptive inner fixing unit is used for fixing a blast pipe; when the device is used, a blasting pipe is inserted into the self-adaptive inner fixing unit, the self-adaptive inner fixing unit conducts self-adaptive adjustment according to the diameter of the blasting pipe, the blasting pipe is clamped and fixed in the self-adaptive inner fixing unit so that the blasting pipe cannot move, the self-adaptive outer fixing unit is tightened, the outer diameter of the self-adaptive outer fixing unit can be reduced, and then the device is inserted into a blasting hole; and then the self-adaptive outer fixing unit is released, so that the outer diameter of the self-adaptive outer fixing unit is enlarged, the self-adaptive outer fixing unit abuts against the inner wall of the blast hole, and therefore, the blast pipe can be fixed in the blast hole. The device is simple in structure and convenient to operate, the self-adaptive outer fixing unit can abut against the inner wall of a blast hole, a blast pipe can be fixed in the blast hole, installation is convenient and stable, the inner fixing unit can adapt to blast pipes with different diameters, replacement does not need to be conducted according to the type of the blast pipe, and applicability is high.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a blasting pipe fixing device for rock and soil blasting. Background technique [0002] Blasting engineering refers to a construction method that uses explosives to excavate soil and stone, and to demolish or destroy foundations, buildings and structures. There are many types of explosives. The most commonly used explosives in construction projects are ammonium nitrate explosives, nitroglycerin explosives and black gunpowder. [0003] Geotechnical blasting refers to blasting operations for the purpose of crushing and throwing rock and soil, such as mining blasting, roadbed excavation blasting, roadway (tunnel) tunneling blasting, etc. Geotechnical blasting is the most common blasting technique. [0004] The current blasting tube fixing device is not ideal for use. During the explosion process, the blasting tube itself is displaced, which will cause the blasting tube to pop out...
