Abstract
The invention discloses an underwater cutting seam cartridge exploding device based on decoupling charge. The device comprises a cutting seam pipe and a detonating cord, two cutting seams are arrangedon the wall of the cutting seam pipe, a decoupling charge bag pipe is arranged in the cutting seam pipe, and comprises a radial bag pipe and an axial bag pipe, the exploding device is sufficiently combined with advantages of cutting seam cartridge and the axial decoupling exploding, the complete protection on excavation foundation bed rock can be formed, blast hole unit explosive consumption is reduced, blast hole excessive exploding can be completely eradicated, the hurt to the reserved rock body is reduced, meanwhile, vibration danger of the exploding impact on the near structure and the surrounding can be controlled, the vibration reduction and isolation effect is obvious, and the comprehensive economic benefit is prominent; in addition, the structure is simple, standard batched production is achieved, in the cartridge making process, a user can carry out work on an on-water work platform, underwater work procedures can be simplified, and practicability is good. The invention further provides a construction method of the exploding device. The construction method is simple, cost is low, safety is high, and the extremely large popularization and application value is achieved.
Description
technical field [0001] The invention relates to a blasting device, in particular to an underwater slotted charge blasting device based on uncoupled charges and a construction method thereof. Background technique [0002] With the further implementation of national infrastructure construction, the construction of port terminals, inland waterways, and cross-river bridge projects has developed rapidly. The geological conditions are dominated by rocks. Ports and waterway projects often use the drilling and blasting method for construction. Blasting excavation has the advantages of low construction cost, The excavation speed is fast, and the technology is becoming more and more mature, and it is widely used. However, the blasting mechanism and construction technical requirements of underwater blasting and land blasting are significantly different due to the difference in the blasting medium, especially for the underwater blasting excavation of bridge pier foundations across river...
