Description

[0001] The invention relates to the technical field of tunnel blasting, in particular to a tunnel blasting shock wave protection device. Background Art

[0002] At present, in the blasting construction of mine tunnels, ordinary cover protection or unprotected blasting construction is usually adopted. The blastholes are not blocked or the tunnel blasting is carried out in a conventional blocking manner. The vibration of the blasting is large, and the shock wave is large. The blasting shock wave may cause soil and rocks to splash, and may cause certain damage to the equipment on site, such as electronic equipment, ventilation ducts, lighting, etc. Therefore, a protective device is needed to weaken the shock wave that may cause damage to the equipment; At present, some larger protective devices are time-consuming and labor-intensive to carry, and the blasting vibration and blasting shock wave generated during the blasting process may also make the protective device unstable. Also, because the protective device is in frequent contact with flying rocks or shock waves, a protective structure that can be easily replaced can be used. For this purpose, a tunnel blasting impact safety protection device for blasting is proposed. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies, the present invention provides a tunnel blasting shock wave protection device to solve the problems raised in the above-mentioned background technology, including a base, a universal wheel is arranged under the base, a protective wall is arranged on the base, a support mechanism is fixedly connected to the back of the protective wall, and the protective wall panel is composed of a frame and a wall body composed of reinforcing ribs, and the wall body includes a reflective layer, a barrier layer and an energy-absorbing layer. Preferably, the support mechanism includes a fixed structure, and a support column with an adjustable angle is fixedly connected to the bottom of the fixed structure, and the bottom of the support column is fixedly connected to the base. Preferably, the protective wall is a frame composed of horizontal beams, vertical beams and inclined beams of reinforcing rib materials.

[0004] Preferably, the protective wall body includes a super-strong alloy steel sheet used as a reflective layer, a fiber resin reinforced composite material layer used as a barrier layer, and a polyurethane foam plastic layer used as an energy-absorbing layer.

[0005] The beneficial effects of the present invention are as follows: the tunnel blasting protection device of the present invention comprises a protection wall structure composed of a frame composed of reinforcing ribs and a wall composed of super-strong alloy steel sheets, fiber resin reinforced composite materials, and polyurethane foam plastics. The surface protection wall structure can sequentially weaken the contact shock wave, thereby protecting and weakening the shock wave and blocking flying rocks. The protection device can be conveniently transported through universal wheels, and can be directly fixed in front of the equipment to be protected, and can be reused to ensure the safety of on-site equipment.
