摘要
结合工程实例,对水平定向钻和顶管方案在燃气管道穿越道路工程中的应用进行比较。对于工期紧张的工程,应优先选择水平定向钻方案;若基于降低造价,则优先选择顶管方案。
The principles and merits and faults of horizontal directional drilling scheme and pipe jacking scheme are introduced. The applications of the two schemes in gas pipeline crossing highway are compared by an engineering case. For tight schedule project, the horizontal directional drilling scheme should be recommended, while for economic reason, the pipe jacking scheme is preferred.
