输水管线大口径钢顶管施工技术措施

摘要

输水管线大口径长距离钢顶管施工中,技术措施的正确运用对保证质量安全、降低施工风险具有重大意义.该文从青草沙严桥支线DN3600双线钢顶管施工实践出发,介绍大口径钢顶管施工工艺中的几个问题和采取的对策,以期与同行进行交流和探讨.%During the construction of water transportation pipeline of long-distance large-diameter steel pipe with jacking technic, the correct use of technical measure had a large significance on keeping both safe and quality of project and reducing the risk of construction. Based on the construction practice of DN3600 double -line steel pipe jacking in Yanqiao branch of the project of Qingchasha, several problems and corresponding measures existing in the construction technology of large-diameter steel pipe jacking were introduced in the paper.
