Drainage pipeline laying construction method for sewage treatment
The invention relates to the technical field of sewage treatment, in particular to a drainage pipeline laying construction method for sewage treatment. The drainage pipeline laying construction method comprises the following steps of S1, foundation pit excavation: site selection is carried out, and a foundation pit is excavated according to the requirements of a design drawing; S2, base installation: a plurality of bases used for supporting a drainage pipeline are placed in the foundation pit, and every two adjacent bases are fixed to the bottom face of the foundation pit at equal intervals; S3, pipeline treatment: the surface of the pipeline is coated with an acid-resistant coating, and standing is carried out for 2-3 hours in an environment of 40-46 DEG C, so that a protective layer is formed on the outer side of the sewage pipeline; S4, pipeline placement: the pipeline is placed near the foundation pit; and S5, pipeline putting: the pipeline is put into the foundation pit, the pipeline is pushed to roll on the ground near the foundation pit, and finally the pipeline stably falls onto the bases on the bottom face of the foundation pit. The surface of the pipeline is firstly coated with the acid-resistant coating, then the pipeline is installed, and the corrosion resistance of the pipeline to acid liquid can be effectively improved.
本发明涉及污水处理技术领域，尤其涉及一种污水处理用的排水管道铺设施工方法，包括以下步骤：S1、基坑挖掘：选址，并按设计图纸的要求开挖基坑；S2、基座安装：在基坑内放置多个用于支撑排水管道的基座，相邻两个基座之间等间距固定在基坑底面；S3、管道处理：在管道表面涂覆耐酸涂料，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、管道放置：将管道放置在临近基坑的附近；S5、管道投放：将管道向基坑内投放，通过推动管道，使其在基坑附近的地面上滚动，并最后平稳落入至基坑底面的基座上。本发明通过先对管道的表面进行涂覆耐酸涂料处理，然后再对其进行安装，可以有效地提高管道对酸性液体的耐腐蚀能力。
