摘要
Abstract
This paper based on current construction equipment in building pit engineering,aims to research technique of reducing dust pollution of sprayed concrete.By analyzing the technical principles of the dry-sprayed concrete widely used in building pit slope engineering and the causes of dust pollution,this paper holds that the main reason of the dust pollution is the inferior mixing and not fully wetting between dusty cement particles and water.And this paper develops two technical methods of mixing type spray gun and the dry-sprayed concrete with cement paste,which both can make cement particles and water fully mixing and wetting,reduce the dust concentration of sprayed concrete effectively,and reduce the environmental pollution of sprayed concrete in building pit slope engineering.关键词
