Abstract

The invention discloses a reduction device and method for explosion noise and shock in a tunnel. The reduction device is arranged in an explosion blasthole and comprises a shock reduction layer, a noise reduction layer, interlayers and a sealing plug; the shock reduction layer is an elastic piece of which one end is provided with an opening, and the shock reduction layer is filled with air and wraps the outer side of the noise reduction layer; the noise reduction layer is internally provided with a noise absorption material and provided with an opening which is in the same direction as that ofthe shock reduction layer, and the sealing plug for sealing the opening is arranged at the opening of the noise reduction layer; the sealing plug comprises a plurality of layers of noise absorption materials; a space for containing explosives is formed in the noise reduction layer and internally provided with the multiple interlayers. According to the reduction device and method for the explosionnoise and shock in the tunnel, the noise and shock which are generated during tunnel explosion construction can be reduced, and harm of the noise and shock to the surrounding environment is relieved.

Description

technical field [0001] The invention relates to a device and method for reducing blasting noise and vibration in a tunnel. Background technique [0002] At present, tunnel construction mainly adopts three main methods: drill and blast method, shield method and tunnel boring machine method. Among them, the drill and blast method is to excavate tunnels by drilling, filling with explosives, and blasting. Due to its low excavation cost and strong adaptability, it is a commonly used tunnel excavation method at home and abroad. However, the blasting vibration has great harm to the surrounding rock of the excavated tunnel, the ground surface and other buildings. It is easy to aggravate the deformation of the surrounding rock of the excavated tunnel, cause the instability of the surrounding rock, and may also cause road settlement or building damage due to improper blasting construction. The collapse caused huge economic losses. In addition, because the space in the tunnel is rela...
