我国工程建设规模随着社会深入发展日益不断扩大,其中长输管线工程项目所占比重逐年上升,在敷设长输管线期间,会遇到诸多障碍,比如河流、铁路或者是公路等等。而在遇到阻碍时,最常用的方式就是顶管穿越技术。我国土地资源辽阔,道路山河错综复杂,致使长输管线施工带来了一定的难度,在此种状况下,顶管穿越技术的应用,可对建筑物、隐蔽物起到一定的保护作用,同时,还可确保管线敷设深度的安全性。基于此,本文特此研究了长输管线顶管穿越施工技术及其施工要点,为实际借鉴提供有效参考。
With the deepening of social development, the scale of construction in our country is constantly expanding. Among them, the proportion of long-distance pipeline projects has been on the rise year by year. During the laying of the long-distance pipeline, many obstacles such as rivers, railways and highways are encountered. In the face of obstacles, the most common way is to pipe through the technology. Due to the vast land resource and complicated rivers and lakes in our country, construction of long-distance pipeline brings some difficulties. Under such circumstances, the application of pipe jacking technology can play a protective role in buildings and concealed objects. At the same time, It also ensures the safety of the pipe laying depth. Based on this, this article hereby studied the long-distance pipeline jacking construction technology and construction points, to provide an effective reference for practical reference.
