Along with the increase of road construction mileage and number in successive years, newly-built roads are inevitable to need to excavate tunnels, and the recent practice also shows that the increase rate of the number of road tunnels or the mileage far exceeds the increase rate of the mileage of the roads. The construction based on the drilling and blasting method has less capital investment; the dependence degree on large machinery is low, and construction can be carried out only by simple machinery; the construction method has the advantages that the construction can be effectively carried out under various geological conditions, and the highway tunnel is generally constructed by a drilling and blasting method at present.

In the excavation of tunnels, excavation blasting causes two main problems, vibration and shock waves respectively. The blast vibration affects the stability of the surrounding rock and creates damage to adjacent structures, while the blast shock wave can compromise the safety of workers and construction machinery in the tunnel. There is a great deal of literature on the response of structures to blast vibrations and the damage of vibrations to structures. Most energy in the excavation blasting is consumed in the process of breaking rock strata to form blasting vibration and throw rock blocks, and a small part of residual energy is released in air to enable the air to be rapidly compressed to form air shock waves. The air shock wave can cause harm to the safety of personnel and equipment in the tunnel, the personnel and the equipment are required to be far away from a blasting area in the blasting process, the shock wave and flying stones are avoided, and much time is required for evacuation of the personnel and the equipment and recovery of production after blasting.

The existing protection device mostly adopts concrete wall stones and fine sand, is heavy, inconvenient to transport, cannot be reused, causes resource waste, does not have the function of reducing dust, easily produces some dust in the construction process, and influences operating personnel.
