普通干喷法施工中存在较严重的粉尘问题。为此,国内外对干喷机作了不少改进。随着科学技术的发展,湿喷机的研制有了很大进步。大量实践表明,采用湿喷是解决粉尘问题的有效途径。瑞典基律纳铁矿年总喷量两万米~3中,湿喷占3/4.我国鹤壁煤矿的湿喷机已喷射6000多米巷道,新汶、萍乡、邯邢、十五冶等试用了各种罐式湿喷机,四川省煤建公司五处等采用活塞泵式湿喷机也取得了不少经验。本文拟对国内外湿喷机及湿式喷射混凝土有关情况作一介绍,不当之处,敬请指正。 Ordinary dry spray method in the construction of more serious dust problems. To this end, at home and abroad made a lot of dry jet improvement. With the development of science and technology, the development of wet spraying machine has made great progress. A lot of practice shows that the use of wet spray is an effective way to solve the problem of dust. Sweden Kiruna iron ore total annual spray volume of 20,000 meters ~ 3, wet spray accounted for 3 / 4. China’s Hebi Coal Mine wet jet has shot more than 6000 meters roadway, Xinwen, Pingxiang, Handan Xing, 15 Metallurgical trial A variety of canister wet jet machine, coal construction company in Sichuan Province, five using piston pump wet spray machine has also made a lot of experience. This paper intends to wet spraying machine at home and abroad and wet sprayed concrete to make an introduction to the situation, inappropriate, please correct me.
