Sewage pipeline construction process
The invention relates to the technical field of sewage pipeline construction, in particular to a sewage pipeline construction process. The sewage pipeline construction process comprises the following steps that S1, surveying is conducted for construction setting-out; S2, mechanical grooving is adopted, the situation that a soil structure of a base is not disturbed or damaged is ensured, meanwhile, a layer 20-23 cm away from the base is not dug, manual digging is adopted, tree roots, sludge, humus soil and garbage below the base are cleaned up, plain soil is replaced and buried, and the base is compacted in a layered mode; S3, a sand cushion layer is laid, in addition, the outer side of a sewage pipeline is coated with a modified wear-resistant coating, and standing is conducted for 2-3 hours in the environment of 40-46 DEG C, so that a protection layer is formed on the outer side of the sewage pipeline; S4, the pipeline is installed; S5, water leakage detection is performed; and S6, groove backfilling is carried out. According to the construction process, the compression resistance of the sewage pipeline is effectively improved.
本发明涉及污水管道施工技术领域，尤其涉及一种污水管道施工工艺，包括以下步骤：S1、测量施工放线；S2、采用机械挖槽，确保基底土壤结构不被扰动或破坏，同时距基底20cm～23cm的一层不挖，改由人工清挖，基底之下的树根、淤泥、腐殖土以及垃圾清理干净，并换填埋素土，分层压实基底；S3、铺设砂垫层，另外在污水管道外侧涂覆改性耐磨涂料，在40℃～46℃的环境下静置2～3小时，使得在污水管道的外侧形成保护层；S4、安装管道；S5、漏水检测；S6、沟槽回填。本发明有效地提高了污水管道的抗压性能。
