Description

Technical Field

[0001] The utility model relates to the field of underwater blasting operations, and specifically relates to an integrated charge structure for underwater drilling and blasting. Background Art

[0002] Underwater drilling and blasting technology is a controlled blasting operation carried out underwater, which uses blasting efficiency to damage or demolish underwater rock and soil or artificial structures. This technology has a wide range of applications in fields such as marine construction, oil and gas exploration, underwater mining, demolition, dredging and excavation, seismic exploration, and marine research. The charge for underwater blasting operations is special. So far, there is no standard specification charge at home and abroad. Usually, PVC pipes, plastic film wrapping, etc. are used to process the charge according to the site conditions, and it needs to be integrally processed and formed and loaded as a whole.

[0003] PVC pipes are generally applicable to shallowly buried underwater rock and soil, with a narrow application range; PVC pipes are of fixed length and need to be processed on site according to the designed charge length of each single hole, with cumbersome procedures; the initiating charge is pre-installed at the bottom of the pipe, and stray current is prohibited at the processing site, with high site requirements.

[0004] The quality of the plastic film wrapping is not easy to control. The shape of the charge is wrinkled and not straight. During the loading process, the wrapping film is easily scratched, which may cause large deformation of the charge and make it impossible to load; there is a hidden danger of misfiring due to the detonator being easily extruded by external forces during loading; the leg wires of the detonator are easily scratched and damaged at the outer conduit nozzle during the loading process, resulting in abnormal initiation and the charge having to be taken out and reprocessed.
