The influence of the tunnel engineering construction on the environment is shown as the influence of the construction on surface groundwater, the influence of waste slag on the environment, the influence of construction wastewater and domestic sewage on the environment and the like. At present, domestic and foreign researches are mostly based on the aspects of underground water environment negative effect evaluation systems and mutual influence mechanisms of tunnels and underground water environments. The research on predicting the characteristics of underground water and protecting the underground water environment in construction is still insufficient, and the research on the protection and recovery of underground water resources in sensitive areas is still weak. The influence of the abandoned tunnel slag on the environment and the comprehensive utilization technology research of the abandoned tunnel slag are not systematic, and the method is particularly suitable for the detection method of the abandoned slag quality, the reduction treatment measures and the like. Therefore, the research on the construction environment protection and restoration technology of diversion tunnels in ecological sensitive areas needs to be carried out by relying on diversion projects in the Yunnan, and the research on the influence and restoration technology of tunnel construction on the peripheral environment, the influence and protection measure of tunnel construction on underground water, the influence and protection measure of tunnel waste slag on the environment, and the treatment and utilization technology of production and living wastewater of tunnel construction are mainly researched.

4. In the prior art, the viscosity of the waste slag is obviously greater than that of common fluid such as gas and liquid, so that the corners of the gate valve can have residual accumulation and cannot be well cleaned.
5. In the process of transporting the waste slag in the prior art, the flowability of the waste slag is relatively weak due to the solid characteristic of the waste slag, and the flowability of the waste slag is not as good as that of gas and liquid, and how to improve the waste slag from the mechanical structure is not good.
