高压水射流破碎技术是近年从国外引入的一种水泥混凝土路面维修新技术。文章介绍高压水射流工作原理及破碎机理,结合在河北省京石高速公路定兴线完成的高压水射流破碎与人工风镐破碎对比试验,总结高压水射流破碎技术的特点。
High pressure water jet crushing technology is introduced in recent years, a new type of cement concrete pavement maintenance. This paper introduces the working principle and crushing mechanism of high pressure water jet, and compares the high pressure water jet crushing and manual air lift pulverizing comparative tests done at Dingxing Line of Jingshi Expressway in Hebei Province. The characteristics of high pressure water jet crushing technology are summarized.
