Step 1: Prepare.
Before sewer installation, it is necessary to make preparations. First of all, determine the location and length of the sewer, as well as the tools and materials needed for installation. Secondly, it is necessary to clean up the sundries around the installation location to ensure that the installation location is clean and tidy.
Step 2: Dig a sewer ditch.
Installing a sewer requires digging a ditch to place the sewer pipe. In the process of digging trenches, we need to pay attention to the depth and width of trenches and the slope of trenches. The depth of the ditch should be determined according to the diameter of the sewage pipe and the climatic conditions in this area. Generally speaking, the depth should be between 50 and 100 cm. The width of the trench should be 20 to 30 cm wider than the diameter of the sewer pipe, which is convenient for installation and maintenance.
Step 3: Install the sewer pipe.
After digging the trench, you can start installing the sewer pipe. First of all, according to the length and bending degree of the trench, the sewer pipe needs to be cut to an appropriate length, and the elbow and tee should be connected well. Then, put the sewer pipe into the trench, and adjust the height of the sewer pipe according to the slope of the trench to ensure that the slope and flow direction of the sewer pipe are correct.
Step 4: Connect the drain pipe and sewer pipe.
After the installation of sewer pipe is completed, it is necessary to connect the drainage pipe and sewer pipe. First, put the drain pipe into the end of the sewer pipe and fix it with rubber washer and retaining ring. Then, connect the drain outlet with the drainage pipeline to ensure that the joint is sealed and reliable.
Step 5: Fill the ditch and tamp the soil.
After the installation and connection of sewer pipes are completed, it is necessary to fill ditches and tamp the soil to ensure the stability and safety of sewer pipes. The filling material of pipe trench should be sand or gravel, and the thickness and compactness should be controlled during filling to avoid damaging the pipeline.
Matters needing attention
In the process of sewer installation, the following points should also be noted:
1. Select the appropriate sewage pipe.
When choosing sewer pipes, we should choose suitable pipes and specifications according to the climatic conditions and use environment in the region. Generally speaking, the material of sewer pipe can be PVC pipe, cast iron pipe, steel pipe, etc. The specifications should be determined according to the displacement and use environment.
2. Keep the sewer pipe unobstructed.
After the installation is completed, the sewer pipe should be cleaned and inspected regularly to keep it unobstructed. During use, foreign matter and grease should not be poured into the sewer to avoid blocking and damaging the pipeline.
3. Observe the safety operation procedures.
In the process of sewer installation, you should abide by the safety operation rules and wear safety protection articles to ensure that you will not be hurt during installation.
Seek professional help
Don't try to install sewers without relevant experience and technology. You should seek professional help and guidance to ensure the quality and safety of installation.
