Abstract

The invention relates to a drilling and blasting method tunnel assembly type blasting construction method, and belongs to the field of tunnel drilling and blasting method construction. A single-hole dynamite container is prefabricated in advance according to the collected blast hole surrounding rock information, and the dynamite container is put quickly on site, so that charging convenience is realized. Slurry is packaged in charging pipes of the single-hole dynamite containers for peripheral holes, hydraulic fracturing blasting is achieved, and the blasting efficiency is improved. An unmanned mechanical arm is used for installing the single-hole dynamite containers, personnel participation is reduced, and the construction safety level is improved. The single-hole dynamite containers are provided with blasting control terminals, information interaction is carried out between remote blasting control equipment and the blasting control terminals, after all the single-hole dynamite containers are installed, position information is sent to locate the positions of blast holes, and the remote blasting control equipment carries out blast hole identification and detonation delay time design according to the position information of the blast holes and by means of a preset program, and intelligent blasting is achieved. The blasting control terminals are provided with clock units for overall timing, and when a communication signal is delayed, the blasting time is accurately controlled through the clock units.

Description

technical field [0001] The invention belongs to the technical field of tunnel drilling and blasting construction, and relates to a drilling and blasting tunnel assembly blasting construction method. Background technique [0002] At present, in addition to the construction of urban rail transit using the shield method or TBM method, road tunnels, railway tunnels, and hydraulic tunnels are still mainly constructed by drilling and blasting methods. Tunnels constructed by the drill and blast method require a large number of personnel to carry out on-site construction, with many operators, high safety pressure, and many uncontrollable factors in the construction period. [0003] Drilling and blasting tunnel construction has gone through the following construction steps: measurement→drilling→charging→blasting→ventilation→slagging and risk removal→spouting support. The existing drilling and blasting blasting requires on-site manual operations such as positioning, drilling, chargin...
