Deep hole presplitting blasting split mounting type charging device and implementation method

The invention discloses a deep hole presplitting blasting split mounting type charging device and an implementation method, and relates to the technical field of geotechnical engineering blasting, the deep hole presplitting blasting split mounting type charging device comprises a bottom reinforcing charging barrel, a plurality of sections of standard prefabricated charging pipes and a middle limiting disc. During blasting operation, the multiple sections of standard charging pipes and the bottom reinforcing charging barrel are spliced on site to obtain the pre-splitting blasting charging structure, on-site cartridge and bamboo strip fixing is not needed any more, modular assembly is achieved, the operation efficiency is improved, and the production cost is reduced. In addition, the standard charging pipes are adopted to replace bamboo canes to fix the uncoupled cartridges, the standard charging pipes are simple in structure, convenient to manufacture and capable of being prefabricated on site in advance, pres
