某水电站左岸治理工程土石方开挖过程中产生大量的粉尘,施工现场易遭受粉尘污染,影响施工整体环境。通过建立严格的管理制度,实施合理的降尘措施,采取规划布置五个供水蓄水池,供水管线覆盖到各个施工作业面,并对出渣车辆进行排气管改造以及对拉运的弃渣进行冲洗、洒水等方法,有效地控制了施工场区造孔、爆破、甩渣、翻渣和运输等明挖法施工环节产生的粉尘量,减弱了粉尘对工程施工造成的不利影响,保障了良好的施工环境。
During the earthwork excavation in the left bank slope treatment work in a Hydropower Station , a large a-mount of dust is produced , which seriously affect the overall construction environment .Thus, with the establishment of a strict management system , some reasonable dust suppression measures are implemented .Five water storage tanks are arranged to ensure that all construction planes are reached by water pipelines .The tail exhaust pipes of the transport ve-hicles are renovated .And the abandoned construction waste is rinsed and sprinkled with water .With these measures , the dust generated by the open-cut construction such as drilling , blasting , dumping and transportation of the waste is ef-fectively controlled .The adverse impact of the dust on project construction is greatly alleviated , which guarantees a good construction environment .
