Description

Technical Field

[0001] The invention belongs to the technical field of concentrated energy blasting, and in particular relates to a concentrated energy pipe cover installation device and an installation method. Background Art

[0002] Blasting construction has been widely used in urban subway excavation projects. However, due to the increasingly strict control of blasting equipment such as detonating cords in cities, the source of detonating cords in many cities is limited. The segmented charging structure of detonating cords is a key technology to ensure the smooth blasting effect of underground projects, but due to the limited supply of detonating cords, it is difficult for some projects to adopt this charging structure. In this context, the shaped tube hood came into being as a detonation transmission device to replace the detonating cord. The explosion transmission effect of the shaped tube hood is closely related to the operator's proficiency, which directly affects the explosion transmission distance and blasting effect. In addition, shaped blasting requires segmented charging and has high requirements on the charging quality, which makes the construction process complicated and time-consuming.

[0003] At present, the diameter of the energy-gathering tube cover is the same as the diameter of the explosive strip. During installation, the worker needs to first cut the end of the explosive strip with a knife, then press the front end of the energy-gathering tube cover to make its diameter smaller than the diameter of the explosive strip, and then slowly insert the energy-gathering tube cover into the explosive strip. When the explosive overflows from the opening of the energy-gathering tube cover, it indicates that the explosive has filled the inside of the energy-gathering tube cover, and the energy-gathering tube cover and the explosive are coupled. However, due to the differences in workers' operating proficiency and installation techniques, problems such as poor coupling between the energy-gathering tube cover and the explosive, tilted installation, and waste of explosives often occur, which in turn affects the explosive transmission effect of the energy-gathering tube cover, and ultimately has an adverse effect on the blasting effect. In addition, in the process of loading the explosive strip with the installed energy-gathering tube cover into the blasthole, the worker needs to use a gun stick to push the explosive strip into the blasthole section by section. Since the shaped charge is divided into many sections and the distance between the explosive strips needs to be manually controlled, the construction process is cumbersome and time-consuming. At the same time, since the diameter of the blasthole is larger than the diameter of the explosive and the internal situation of the blasthole is complicated, it is easy to have irregular charging during the charging process, which further affects the explosive transmission effect of the energy-gathering tube cover. Summary of the invention
