Abstract

The invention discloses a drilling explosive filling device for tunnel construction blasting in the field of road and bridge engineering construction, which comprises a mounting seat slidably arranged on a rack and a rotating shaft rotatably mounted on the mounting seat, the rotating shaft is in a hollow penetrating shape, one end of the rotating shaft is an explosive inlet, and the other end of the rotating shaft is an explosive outlet; a driving gear is fixedly installed at the end, close to the pesticide inlet, of the rotating shaft, and a drill bit used for drilling is arranged at the end, close to the pesticide outlet, of the rotating shaft. The drill bit is closed to close the medicine outlet; and the drill bit is opened to open the medicine outlet. According to the device, drilling and explosive filling can be automatically carried out, the drill bit is opened after drilling is completed, negative pressure is formed in the drill hole through the recovery action that the drill bit leaves the drill hole, the explosive located in the hollow rotating shaft is sucked into the drill hole, it is avoided that the explosive is damaged due to rigid extrusion and friction of the hole wall in the explosive filling process, manual operation is avoided, and the explosive filling efficiency is improved. The explosive is protected, the economic cost and the time cost of drilling and explosive filling are saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering construction, and specifically relates to a drilling and filling device for blasting in tunnel construction. Background technique [0002] Tunnels are key and key projects in the construction of roads and railways. With the development of railway construction and the advancement of science and technology, tunnel excavation methods have been developed rapidly. During tunnel construction, it is necessary to remove the soil and rocks from the excavation section of the tunnel. In order to improve the efficiency of the removal operation, it is necessary to use explosives for blasting. In order to prevent explosives from causing damage to areas that do not need to be cleaned, multiple groups of small-equivalent explosives are reasonably arranged on the tunnel section during blasting. The traditional layout method mainly uses manual drilling and charging, and there is a lack of corresponding p...
