水利工程顶管施工工期影响因素及对策

Impact Factors and Countermeasures of Pipe Jacking Construction Period of Water Conservancy Project

如何科学合理的安排好施工计划,把控关键工序路线,合理调控好各个工序的搭接工作,确保每个节点工期按期完工,是保证主体结构工期目标顺利实现的前提条件。前期反复研究商定工程建设方案,完成联机调试,然后依次进行试顶、顶管贯通、顶管、灌浆及附属工程。

How to arrange the construction plan scientifically and reasonably,control of the key process route,resonable regulation for the overlap work and on-time comletion of each nodal period are the preconditions to ensure the successful achievement of the main structure’s schedule targets.The project construction plan was discussed and studied repeatedly in the early stage,and the on-line debugging was completed,followed by test jacking,pipe jacking penetration,pipe jacking,grouting and ancillary works in sequence.
