Drainage pipes are an essential type of living configuration for modern family life. Despite strict regulations on the acceptance of drainage pipes in the country, there are no specific requirements for the daily inspection of drainage pipes. In fact, the detection of drainage pipes is We have an important significance in our work and life. Mastering certain drainage pipeline inspection techniques plays a significant role in preventing accidents of all kinds. So, how do you do a drainage inspection ? In order to help everyone understand more, here are some suggestions for everyone here today.
Drainage pipe introduction
The length of the drainage pipeline is calculated and calculated for all drainage mains, trunks, branches and inspection wells, connection wells, etc. Excluding connection pipes, inlet pipes and open channels between the stormwater outlet and the drainage pipeline. The calculation shall be based on a single pipe, ie if there are two or more side-by-side drainage pipes on the same street, the length of the sum of each drainage pipe shall be calculated.
Drainage channel dredge
The first step to clear the drain: Cover the overflow of the pool or bathtub with a damp cloth. Most kitchen sinks have no overflow, but if there is another pool next to the pool you are cleaning, you can use a damp cloth to plug the drain of another pool. Some families have two bathrooms next to each other in the adjacent room. They may use the same drain.
In such a situation, you must plug the sink drain and overflow of the other bathroom. Showers generally have no overflow, while baths are generally available. All of these mouths are covered with a damp cloth so that the hand pressure bowl pump works.
Drainage pipe cleaning
1 It is relatively simple to clean the drains of households. You can put vinegar and baking soda together in water, then heat and boil them, and pour them into the sewer. After waiting for bubbles in the pipes, rinse them with clean water. In this way, the garbage and dirt remaining in the drainage pipe will be softened and decomposed by vinegar and baking soda, and the flushing can not only achieve the purpose of cleaning, but also effectively remove the odor.
2 You can also choose the common drain cleaners in supermarkets. You can pour some of these cleaners into the sewers. Wait about half an hour later to clean them with hot water. Within half an hour, You can also try to clean the sewers with special cleaning tools, such as glass steel sheets. This method can also achieve good decontamination and odor removal.
Drainage pipe inspection
First, closed water test
It should be noted that the drainage pipeline is also known as the confluence of sewage and rainwater. Generally used is the method of direct transportation without pressure. Therefore, according to the national water pipeline construction and acceptance requirements, we can use the closed water method to conduct a good sealing test. The specific operation refers to the construction and acceptance of the water supply and drainage pipeline project. The provisions of the Code can be.
Second, the experimental inspection of the length of the pipe
According to the national standards, the test section should be separated according to the well spacing, the length can not be greater than one kilometer, and the well test should be carried out during the test. Therefore, we must pay particular attention to the length of the experimental inspection during the test process. After two or three short tubes are laid, the test can be performed. This will make the process of test inspection easier.
Third, test inspection time
Because our country has a vast area and the specific conditions vary from place to place, we must choose the time for experimentation according to local conditions. Especially in the southern region, the groundwater level is higher than in other places. Therefore, if heavy rain or heavy rain is encountered during the rainy season, drifting pipes and the like are likely to occur. At this time, we need to detect it and put it in the pipeline. For filling pressure, it is necessary to remember to block the reserved hole beforehand. If the pipeline we used has been subjected to strict inspection, that is to say, the interface has been reserved before the water-rejection test, then we only need to follow the backfill. The request for backfilling work will be fine.
IV. Test head
In fact, there is a very detailed description of the provisions of the test head specification in China, but in order to better check the tightness of the well, we better feed water to the wellhead of the inspection well.
Drainage pipe renovation
There is also a lot of attention to the specific construction. When excavating the protection trench in the early stage, it is necessary to do a good job of prevention and do a good job of supporting work in order to avoid landslides based on the specific conditions of the local soil. In some large buildings, or under the high-voltage poles, we must pay more attention to safety construction, and one side of the ground sinks or deforms. Must strictly follow the requirements of the drawings.
Drainage pipeline construction plan
Tiling drainage pipe construction method
(1) Drainage pipeline trench earthwork
Construction sequence: Pipe line measurement. Positioning → Trench excavation
(1) The excavation of earthwork shall be managed by special persons, and the natural foundation shall not be disturbed. The elevation control at the bottom of the trench shall be within ±20mm.
(2) Before the earth excavation, the excavation section map shall be calculated by the full-time surveyor according to the designed elevation and planned line positions. The line shall be drawn with the instrument and steel ruler at the site, and the line shall be sprinkled with white ash as the trench. in accordance with.
Editor's summary: The inspection work in the drainage pipeline is a highly professional job. Therefore, if there is a problem with the drainage pipeline in the home, it is best for everyone to ask a professional power master to come for repair if they blindly split. Detection, it is easy to cause irreparable damage!
