非开挖技术在济青高速公路工程中的应用

Application of Trenchless Technology to Jiqing Highway Project

在治理济青高速公路因渗滞水的影响，造成路基、路面损坏的工程中，根据工程特点，采用了不影响交通、不破坏道路结构、不破坏环境、施工速度快、施工精度高、施工成本低、社会效益显著的水平定向钻进非开挖技术，非开挖技术是利用不开挖的相关技术对地下管线、管道进行铺设、修复或更换的高新技术，该技术在河道堤防、水库大坝的排水，以及铺设供水、排污等管线中有着广泛的应用前景。

Because in governs the Jiqing blue highway to infiltrate the slack water the influence, creates the roadbed, in the pavement distress project, according to the project characteristic, used has not affected the transportation, not to destroy the roadway structure, not to destroy the environment, the construction speed to be quick, the construction precision was high, the construction cost was low, the social efficiency remarkable Trenchless technology, Trenchless technology is the correlation technique which the use did not excavate to the underground utilities, the pipeline carries on lays down, the repair or the replacement high technology and new technology, this technology in the river course embankment, reservoir dam＇s draining water, as well as laid down pipelines and so on water supply, pollution discharge to have the widespread application prospect.
