Pipe jacking construction method for natural gas pipeline
The invention relates to a natural gas pipeline jacking construction method, which belongs to the technical field of pipeline construction, and comprises the following steps: surveying and setting out, and determining the excavation position and depth of a vertical shaft and the jacking direction of a sleeve; construction of a vertical shaft structure: excavating a vertical shaft and supporting the vertical shaft to facilitate jacking of a sleeve; pipe jacking operation is conducted, specifically, according to the jacking direction determined by surveying and setting out, the natural gas pipeline is jacked into the casing from the jacking well to the receiving well for installation, and the natural gas pipeline is installed in the casing; a gap between the casing pipe and the natural gas pipeline is plugged through a plugging structure; and the vertical shaft is backfilled, and construction is completed. The service life of the natural gas pipeline can be prolonged, and the situation of natural gas leakage is reduced.
本申请涉及一种天然气管道顶管施工方法，属于管道施工技术领域，包括：测量放线，确定竖井开挖的位置和深度以及套管的顶进方向；竖井结构施工，开挖竖井并进行支护，便于进行套管顶进；顶管操作，按照测量放线确定的顶进方向，将套管从顶进井向接收井顶进天然气管道安装，将天然气管道安装至套管内；空隙封堵，采用封堵结构对套管与天然气管道之间的空隙进行封堵；对竖井进行回填，完成施工。本申请能够延长天然气管道的寿命并减少天然气泄漏的情况发生。
