Comprehensive Solution for Improving Work Environment of Construction Using Track and Electrical Maintenance Equipment in Tunnels
Regarding the construction scenario of existing track and electrical maintenance equipment in tunnels,carbon monoxide and particulate matter pose the greatest harm to construction personnel during the mechanized construction process of tunnels.This article designed a modular exhaust gas purification device that can be installed on the roof,using a multi unit parallel connection scheme to make the purification device suitable for engines of different power levels.To solve the problem of exhaust gas accumulation under grouping construction conditions,an auxiliary ventilation system has been designed,which can be installed on flatbed trucks and incorporated into the construction grouping to achieve forced ventilation inside the tunnel.To solve the dust problem in the construction operation area,an atomization spray dust reduction system has been designed.The results show that the exhaust gas purification device can achieve high purification rates of carbon monoxide and particulate matter,and can meet the requirements of diesel engines.The auxiliary ventilation system can further purify the air inside the tunnel,optimize the construction environment for workers,and achieve design goals.The spray dust reduction system can further optimize the working environment of tunnels.
