Sewage pipeline construction process
The invention relates to the technical field of municipal pipeline construction, and relates to a sewage pipeline construction process. The sewage pipeline construction process comprises the followingsteps of (1) excavating a working well; (2) installing jacking equipment; (3) mounting a jacking pipe; (4) dismantling the jacking pipe; (5) coating a lubricating layer; and (6) jacking a sewage pipeline. A lubricant comprises the following components of, by mass part, 50-55 parts of sodium stearate, 30-35 parts of acrylic emulsion, 10-15 parts of water, 1-3 parts of sodium hexametaphosphate, 1-1.5 parts of polyvinyl alcohol and 1-2 parts of oleic acid. The sewage pipeline construction process has the effect of improving the construction efficiency of the sewage pipeline.
本发明涉及市政管道施工的技术领域，涉及一种污水管道施工工艺，其包括以下步骤：步骤（1），开挖工作井；步骤（2），安装顶进设备；步骤（3），安装顶管；步骤（4），拆除顶管；步骤（5），涂覆润滑层；步骤（6），顶进污水管道；润滑剂包括以下质量份数的组分：硬脂酸钠50‑55份；丙烯酸乳液30‑35份；水10‑15份；六偏磷酸钠1‑3份；聚乙烯醇1‑1.5份；油酸1‑2份。本发明具有提高污水管道的施工效率的效果。
