摘要
顶管施工作为一种非开挖技术,因其具有工期快、环境污染小、交通影响小、节约用地、减少拆迁成本等优点,被广泛应用于城市地下管道或隧道等工程施工中,且呈大直径趋势发展。从技术和经济角度,结合工程实例,对大直径顶管施工技术的应用进行介绍,并对其造价进行了分析。
The pipe-jacking technology is a non-excavation technology, and is widely used in the engineering construction of urban underground pipelines or tunnels because of fast construction period, small environmental pollution, little traffic influence, economized land and decreased removal cost, and shows the large diameter trend. This paper introduces the application of large-diameter pipe-jacking construction technology from the angles of technology and economy with the engineering examples, and analyzes its cost.
