The sprayed concrete resilience amount refers to the resilience amount of sprayed concrete when aggregate, water or mixed concrete is sprayed on surrounding rock in the process of spraying concrete, and the concrete which falls off partially is the resilience amount of sprayed concrete because the concrete cannot be coagulated in time. Therefore, the control of the rebound quantity not only relates to the supporting quality of the sprayed concrete, but also plays an important role in the cost control of engineering. Research shows that the rebound quantity of sprayed concrete in the current tunnel engineering is generally about 20% -30%, and the loss is large. Because the rebound quantity of the sprayed concrete has a plurality of factors, including the proportion of the concrete, the air quantity sprayed during the spraying of the concrete, the distance between the spraying nozzle and the rock surface, and the like, the rebound quantity is unavoidable. The conventional tunnel construction engineering has quite transparent profit, and if the construction control is not good, loss can be caused, so that the control of the rebound amount of the sprayed concrete in the construction process is an important part of the control of the tunnel construction cost, but the rebound amount of the sprayed concrete is only controlled, and the rebound amount concrete is basically untreated, so that if the rebound amount of the sprayed concrete can be reused, the construction engineering has great economic value.
