To realize the beautification of urbanization and facilitate the lives of citizens, sewage discharge has become a major issue. In order to be able to efficiently discharge municipal sewage, the sewage discharge pipe has become the primary consideration for urban planning. The drainage pipe mainly assumes the tasks of drainage such as rainwater, sewage, farmland drainage and irrigation, and so on. Have you learned about the specification of the drainage pipe? Sewage pipe installation precautions? Let's go and see it together.
Sewage pipe specification
In order to be able to efficiently discharge municipal sewage, sewage pipes have become the primary consideration for urban planning. The drainage pipe mainly undertakes the tasks of drainage such as rainwater, sewage, farmland drainage and irrigation. Basically used throughout the city, including the drainage of highways. Of course, how to regulate so many sewage pipes is also a very important issue.
Drainage pipe specifications have the inner diameter DO (100mm - 3000mm), length LO (30mm - 200mm) pressure index, I grade II grade III caliber is divided into: flat mouth, enterprise mouth, socket socket, double socket, steel socket. The connection of pipes of different diameters in the inspection well should adopt the water surface or the top of the pipe.
A flexible connection should be adopted for the connection of round pipes. When the conditions are limited, the flexible connection interface should be properly configured along the ground conditions of the pipeline along the pipeline. The pipelines laid in the seismic zone should be implemented in accordance with the corresponding seismic design specifications. For cast-in-place reinforced concrete rectangular pipes, mixed structure rectangular pipes, deformation joints should be set along the line. Deformation joints should pass through the entire section, and the joint distance should not exceed 25m; waterproof measures (such as waterstops and sealing materials) should be provided at the joints.
For pre-stressed concrete tubes, longitudinal pre-stress should be applied, and the value should not be less than 20% of the effective circumferential preload stress. For reinforced concrete or prestressed concrete round pipes of manufactured products, the thickness of the net protective layer of steel bars shall not be less than 12 mm when the wall thickness is 8 to 10 mm, and not less than 20 mm when the wall thickness is greater than 100 mm.
The anti-permeability performance of the factory-made concrete pressure pipeline should meet the water impermeability under the action of the internal water pressure in the design. In areas where the average temperature in the coldest month is less than -3 degrees Celsius, no more than 10 mm in length shall be used for the pipeline structure and the entrances and exits of the pipelines and drains laid by Lumin. No clay bricks shall be used.
In the design of the sewage pipeline, the corners of the water flow should not be less than 90° when the pipeline turns and intersects. The pipeline foundation should be determined according to the geological conditions. Reinforcement measures should be taken for the soft or uneven settlement of foundation, pipeline foundation or foundation, and the interface of the pipeline should be flexible. The minimum depth of soil in the pipeline shall not be less than 0.7m under the roadway according to external loads, pipe strength and other conditions.
Sewage pipe installation precautions
First, the approximate amount of drainage pipes. Prior to the installation of the drainage pipe, the relevant staff or users must initially estimate the usage. Then make purchases based on your own estimates. Avoid buying too much or too little. According to the number of materials to determine the progress of the project's installation.
Second, be sure to use new water pipes regardless of any drain installation. If the water pipe that meets the old house or the second-hand house is damaged, remember not to replace the new one for the sake of economy. You need to know that some parts are new water pipes that are inconvenient to replace. Therefore, it is recommended that you change it and replace it all together. This will ensure that the drain pipe is safe and reliable after installation.
Third, before the installation of the drainage pipe, each drainage pipe and each fitting must be carefully examined in detail. Look at the drain pipe for damage, wear, etc., and pay attention to whether the drain pipe has leakage or not. In addition, the specification of the inspected fittings is indefinable in accordance with the standard of the drainage pipe. When connecting, it must be performed in accordance with the correct method. After the connection is completed, relevant tests are required.
Fourth, the direction of the drainage pipe is also a noteworthy issue for the entire installation project. It is recommended that the drain pipe top is the safest solution. Because if the drain goes underground, if there is a variety of leaks, it is difficult to find timely and effective. The method of taking the water pipe to the top of the water pipe, even if the water pipe leaks, can be discovered in time, and then adopt an effective treatment scheme to make the loss of the user smaller.
Fifth, after the drainage pipe is installed, it must be tested effectively and correctly. Normally, professional and regular manufacturers will take the relevant boost test after installing the drainage pipe. Only after this test is passed can the drain function be officially activated.
Editor's summary: The relevant information about the discharge pipe specification and the discharge pipe installation notice was introduced here. I hope this article will be helpful to everyone.
