浅谈非开挖技术在城市排水工程中的应用研究

Brief Introduction to Trenchless Technology＇s Application in Urban Drainage Engineering

随着国家城镇化进程的快速推进，城市地下管线也日益变得错综复杂。目前城市道路负荷严重，对给排水管道的施工和维护也提出了更高要求。非开挖技术具有不破坏路面、不影响交通、施工速度快、成本低等优点，正在逐步取代传统的开挖施工法，在城市排水工程中应用越来越广泛。本文从非开挖排水管道铺设技术、管道修复技术以及管线更换技术三个方面，对非开挖技术在城市排水工程中的应用作了详细介绍。

With the rapid advance of national urbanization process, urban underground pipeline is increasingly complex. Serious negative impact on the current urban road, and the construction and maintenance of water supply and drainage pipeline is also put forward higher requirements. Trenchless technology has the advantages of no destruct on the road, no impact on traffic, fast construction speed, low cost, etc, and is gradually replacing the traditional excavation method. More and more widely applied in urban drainage engineering. This article gives a detailed introduction of trenchless technology application in urban drainage engineering from the drainage pipeline laying technology, pipeline repair technology and pipeline replacement technology.
