摘要
Abstract
This paper develops an integrated prevention and control technology of"stone slag interception atomization dust reduction"based on regional geological characteristics to address the problem of stone slag entering the river and construction dust on complex high slopes(slopes of 30°-40°)at the inlet of diversion tunnels and bottom water supply tunnels.It has constructed a"graded interception+precise dust reduction"system,which adopts a three-level structure of"slag collection platform+slag blocking wall+passive protection net"for stone slag interception,and optimizes parameters at different elevation sections through numerical simulation.Atomization dust reduction is based on the dynamic adjustment of the combination mode of fog cannon machine and high-pressure spray gun under construction conditions,combined with intelligent control of dust monitoring.Engineering applications have shown that this technology reduces the amount of stone slag entering the river to below 0.5 m³/month,stabilizes the construction dust(TSP)to≤0.5 mg/m³,and reduces it by 95%and 80%respectively compared to traditional measures.The slope safety factor has been increased to 1.35,achieving the synergy between ecological protection and structural safety.关键词
