Abstract

The invention relates to a detonator for hydraulic blasting in the technical field of tunnel construction. An accommodating cavity is formed, the side of the first arc-shaped section close to the second arc-shaped section is provided with an embedded hole, and one side of the second arc-shaped section is provided with a telescopic rod, one end of the telescopic rod is connected to the bottom wall of the embedded hole, and the other end is connected to the bottom wall of the second arc-shaped section. The two arc segments are connected. The hydraulic blasting detonator is equipped with a filling device, including a base, a support column is arranged on the base, a rotary device is arranged on the support column, a turntable is arranged above the turntable, and seven sets of evenly distributed installation holes are opened on the turntable. Among them, installation pipes are installed on the six groups of installation holes, and valves are arranged at one end of the installation pipes. The detonator for hydraulic blasting and its supporting filling device designed by the invention can pre-fill and automatically fill the detonator, improve the filling efficiency of the detonator and reduce manpower consumption.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a detonator for hydraulic blasting and a matching filling device thereof. Background technique [0002] Water pressure blasting is a method of placing the charge in the designed position of the blasted container filled with water, using water as the detonation medium to spread the detonation pressure to destroy the container, and the air shock wave, flying stones and noise can be effectively controlled The blasting method is mainly used in the field of tunnel blasting. [0003] The application document with the notification number CN109373840A discloses a tunnel excavation hydraulic blasting construction method, which includes the following steps: (1) placing the trolley in place and eliminating risks; (2) measuring the cloth holes and drilling holes; (3) installing the detonator , water bag and blasting mud: the peripheral eye is excavated to set the arc periphery o...
