摘　　要：长距离机械顶管施工过程中,该技术将组合式中继间应用于越井顶进中,在遵循先顶后井的总体方案下,对中间检查井采用“中继间顶入、周期分层开挖”的施工方法,同时对中间检查井实行“分层、分周期开挖方式”,在保证先顶后井成功的同时,免除了管道破除切割,加快了工程进度,提高了施工的环保性。This technology applies the combined relay chamber to jack over well in the process of long-distance mechanical pipe jacking construction.Following the overall scheme of jacking first and then well,the construction method of“the relay chamber jacking and periodic stratified excavation”is adopted for the intermediate check well.Meanwhile,“stratified and periodic excavation”is implemented for the intermediate inspection.The technology ensures the success of jacking first and then well,exempts the pipeline from breaking and cutting,speeds up the project progress,and improves the construction of environmental protection.
