Construction process of underground drainage pipeline
The invention discloses a construction process of an underground drainage pipeline, and relates to the technical field of pipeline construction. The construction process includes the following steps of S100, surveying and setting out; S200, well point mounting; S300, groove digging; S400, pipeline concrete foundation construction; S500, pipeline mounting; and S600, pipeline backfilling. A method that machine soil digging is used as a main measure and manual operation is used as an auxiliary measure is adopted. Manual slope repairing is used when the place is dug to the position 30 cm-40 cm away from the groove bottom by a machine, redundant soil at the groove bottom is cleaned away, and therefore the situation that undisturbed soil is disturbed by machine over-digging is avoided; and the soil digging ratio of human to the machine is 20:80, and the cubic meter of earth is stacked outside the position 1.5 m away from the groove side. The construction is easy and convenient, the construction difficulty is low, the construction influence time is greatly shortened, meanwhile, damage to an original structure is low, the reliability of an overall connecting structure is high, the sealingperformance of pipelines is high, and the influence on the safety of the structure is low.
本发明公开了一种地下排水管道施工工艺，涉及管道施工技术领域，其包括如下步骤：S100、测量放线；S200、井点安装；S300、沟槽开挖；S400、管道砼基础；S500、管道安装；S600、管道回填；通过采用机械挖土为主，人工辅助的方法。当机械挖至距槽底30‑40厘米时即用人工修坡，清理槽底余土，以防止机械超挖，扰动原状土；人机挖土比例为20：80，土方堆放在槽边1.5米以外处本发明的施工简单方便，施工难度较低，施工影响时间被大大缩短，同时本发明对原有结构破坏较小，整体连接构造可靠性较高，管道的密封性强，对结构安全影响较小。
