The sewage well is in the earth, how much does the manhole cover need to be higher than the natural

The wells must be flush with our ground. Because his purpose is to prevent people from falling, it must be criticized, and there must be no obstacles, which is what the norm stipulates, and it cannot be higher than the ground.

The sewage well is in the earth, and the height of the manhole cover should be 5 meters higher than the natural ground, I think its degree of standardization is still relatively high, and the sewage well is also very common in rural areas.

Request. 1) An effective bilge water drainage system should be in place to pump out and drain water from any watertight tank, excluding premises containing fresh water, fuel oil, liquid cargo and effective drainage.

2) All distribution boxes and manual valves related to bilge drainage equipment should be located in a normally accessible place.

3) When the ship's roll exceeds 5°, and the freeboard to the bulkhead deck or to the freeboard deck is flooded with water respectively, a sufficient number of drain holes of appropriate scale should be provided to directly discharge the water to the outboard.

4) All engine room sewage wells should be equipped with high-level alarm devices.

Sewage manhole coversHow many tons of height does the ground manhole cover need to be higher than the natural ground.

Abstract "Urban Drainage Engineering Planning Code (GB50318-2000)" 4 4 4 4 sewage treatment plants should be set up with sanitary protection land, new sewage treatment plant sanitary protection distance, before the environmental impact assessment of the construction project, according to the scale of the sewage treatment plant, can be controlled according to Table 4 4 4. The distance between the center of the drainage inspection well and the outer wall of the building shall not be less than 3 meters. Tall trees should be planted within the sanitary protection distance, and construction land for sensitive purposes such as residences, schools, and hospitals shall not be arranged.

The sewage drainage well is more or less close to the building.

Hello, 3M is appropriate. The code requires that the horizontal net distance between the sewage pipe (well) and the building, when the buried depth of the pipeline is shallow than the foundation of the building, it should not be less than, and when the pipeline is deeper than the foundation of the building, it shall be determined according to the calculation, but it should not be less than. That's my answer, thank you

Is there a legal basis?

Wait a minute, I'll find you O.

Urban Drainage Engineering Planning Code (GB50318-2000) 4 4 4 4 Sewage treatment plants should be set up with sanitary protection land, and the sanitary protection distance of new sewage treatment plants can be controlled according to Table 4 4 4 before the environmental impact assessment of the construction project is carried out, according to the scale of the sewage treatment plant. The distance between the center of the drainage inspection well and the outer wall of the building shall not be less than 3 meters. Tall trees should be planted within the sanitary protection distance, and construction land for sensitive purposes such as residences, schools, and hospitals shall not be arranged.

It should be based on Document No. 1356 of the Ministry of Urban and Rural Development of the People's Republic of China.

It is not specified in the requirements of the national standard for the depth of sewage wells.

A sewage well is a small container for the temporary placement of ship sewage and is also an integral part of the ship's bilge water system. The bilge water system is a pipeline system that discharges the bilge water in the cargo hold and furnace compartment of the ship or the stagnant water and seepage water in the double bottom outboard. The sewage well plays the role of temporarily collecting bilge water such as oily sewage generated in the engine room.

The depth of the inspection well should be the height difference from the manhole cover (generally the design pavement elevation is consistent) to the upper part of the well floor. Inspection wells are divided into two types: landing and non-bottoming. The height of the upper part of the general well floor is consistent with the height of the lower inner wall of the lowest drainage pipe, and the height of the bottom is added on the basis of the bottom, which is generally 30cm.

A sewage manhole is a manhole set up on the drainage piping system to inspect and clean the pipes. At the same time, it also plays a ventilation role in connecting the pipe section and the piping system. The pipe section between two adjacent wells should be in a straight line, therefore, inspection wells need to be set up at the place where the pipeline section changes, the slope changes, the intersection and the elevation change, and the inspection wells need to be set up in sections on the excessively long straight pipe section (according to the pipeline diameter and the type of rain and sewage).

Summary. If the sewage well is used for urban construction or old city renovation, the depth of the sewage well is generally within 8 meters, and the diameter of the used sewage pipe is within meters.

What is the relationship between the size of the bottom of the sewage well and the depth of the well? Deep.

After inquiry, the state has not made regulations on the depth of the well and the size of the bottom.

The depth of the sewage well is not fixed, such as etc., among them, the depth of the sewage well is generally used. However, it should be noted that no matter which size you choose, you need to confirm the load-bearing and use environment, so that you can use it for a long time.

If the sewage well is used to serve the urban construction or the renovation of the old city, then the depth of the sewage well is generally within 8 meters, and the diameter of the used sewage bureau pipe is within meters.

Hello senior, I am asking about the sewage Xiaozai pipeline in the factory area, the diameter of the connecting pipe is 300mm, and 400mm, what is the depth of Mina Shenqin, meters, meters, meters, and the diameter of the bottom of the well?

The diameter of the wellhead cover plate is 700mm.

Excuse me. The sewage wells are the same size as the mouth of the well.

Is the depth of the well the same as the diameter of the upper and lower levels?

Yes.

Hello, I am glad to answer your question, according to your question, will digging a four-meter-deep well and putting domestic sewage in it pollute the groundwater? Nowadays, everyone will use laundry detergent and laundry detergent to wash clothes, which contain many chemical components, such as phosphorus, pre-bleaching whitening agent, fluorescent brightener, anti-corrosion agent, foam conditioner and so on. This repentance of some domestic sewage containing chemicals, which enters the surface and becomes an underground water source, will not only affect the quality of well water at home, but also cause pollution in ponds and rivers in the wild.

I hope mine can help you.
