近年来,在铺设自来水管道、天然气管道、石油输出管道工程的施工中,地面开沟填埋铺设管道施工方式逐渐被淘汰,顶管施工技术越来越受到施工企业的广泛应用。其中,泥水平衡式顶管技术在施工中有较为明显的技术优势,具有安全性高、施工工期短、适用土质范围广以及对环境干扰小等特点,具有广阔的应用前景。本文通过市政排水工程实际案例,具体分析泥水平衡式顶管在施工过程中出现的质量问题,并及时总结提出相应防治措施,进一步提高该技术的工程适用性。
In recent years, in the construction of tap water pipes, natural gas pipelines and oil export pipeline projects, the construction methods of surface trench ditching and laying pipelines have been gradually eliminated. The pipe jacking construction technology has been widely used by construction enterprises. Among them, the mud-water balance pipe jacking technology has obvious technical advantages in construction, which has the advantages of high safety, short construction period, wide range of applicable soil quality and small environmental disturbance, and has broad application prospects. Based on the actual case of municipal drainage project, this article concretely analyzes the quality problems of mud-water balance pipe jacking during the construction, summarizes and puts forward the corresponding prevention measures in time, and further improves the engineering applicability of this technology.
