in general, the sewer can not be modified without modification, because the risk of the transformation of the sewer is relatively large, and a little carelessness will bring a lot of inconvenience to future life. if it is really necessary to change the sewer, it does not mean that it can not. so what should be paid attention to in the sewage transformation? let's introduce it to you.
1、 glue problem at interface
when applying adhesive at the joint, the surrounding of the pipe joint must be cleaned up first, and there shall be no impurities at the joint. when applying glue, both the inside and outside of the pipe fittings should be coated with glue. do not apply glue casually in order to save trouble, which will directly lead to the leakage of the sewer pipe.
2、 low and gradient
in the transformation of the sewer pipe, we must pay attention to the height and inclination of the pipe, and control the inclination of the pipe. although there is no strict requirement on the slope of the pipeline, the height of the water inlet must be higher than that of the water outlet to avoid the phenomenon of backflow. after the installation of the sewer, it is not allowed to raise the ground to achieve a suitable gradient.
3、 length of pipe
the length of the sewer pipe is specified. it should not be too long. if it is too long, the drainage of the pipe will not be smooth, and it is easy to block, and it is difficult to repair if there is a problem.
4、 fixing of water pipes
after the transformation of the sewer, we must do the test of irrigation, check whether there is leakage, if there is no leakage, we must fix the pipe. the pipeline on the ground must be buried with cement or gypsum to avoid the worker accidentally stepping on the next process. don't think it's ok to step on the pipe you bought. if you step on the pipe too much, it will break.
in order to avoid foreign matters falling into the pipeline during the next construction period, sealing treatment must be carried out after the transformation of the sewer pipeline. if the cement slurry falls into the pipeline, once it solidifies, it is difficult to clean it up.
6、 waterproof treatment
after the transformation of the sewer pipe, waterproof treatment should be done to increase a layer of security for the pipeline. when the sewer pipe is reconstructed, a deodorizing elbow must be added to prevent the odor of the sewer pipe from entering the room in the future. however, before adding deodorization elbow, it is necessary to negotiate with the residents downstairs and start the construction downstairs, otherwise it will be difficult to add deodorization elbow.
the above is about the sewer transformation need to pay attention to the matter, i hope to help you. if you have any other questions about sewer reconstruction, you can contact our website at any time: jinan pipeline dredging http://www.sggdst.com ！
