Is there any technical specification for indoor sewage pipe connection to outdoor inspection wells?

The spacing between the storm sewer and the wall is generally 40 to 50mm.

When designing the main pipe diameter of the rainwater pipe, when there is no pressure flow (not full pipe flow), the design flow rate in the pipe is usually about 1m s, and the minimum design flow rate used should be greater than that of the sewage pipe, and the minimum design flow rate in the rainwater pipe when the flow is full.

The principles are as follows: 1. The fire pipe must let the rainwater pipe, because the rainwater pipe is a gravity flow and needs a slope, while the fire pipe is a pressure flow.

2. The burial depth is below the maximum permafrost line in the place.

3. If there is a large load on the ground, it is necessary to determine the buried depth after the impact calculation.

4. What specifications do rainwater pipes have:

The rainwater pipe is the main component of the villa roof drainage system, and its function is to systematically drain the rainwater collected in the roof gutter from the building. Color aluminum rainwater pipes adopt international standard sizes: 2x3 inch (51x75mm), 3x4 (inch rectangular storm water pipes, 3 inches (75mm), 4 inches (100mm) round storm water pipes.

5. If the rainwater pipe is close to the edge of the awning, the rainwater pipe can be led down from the side of the awning with an oblique elbow; If you are far away, you should wear a canopy, but you should add a sleeve.

The technical specifications for the design of sewage pipes are as follows:

1. The fire pipe must let the sewage pipe, because the sewage pipe is a gravity flow and needs a slope, while the fire pipe is a pressure flow.

2. The burial depth is below the maximum permafrost line in the place.

3. If there is a large load on the ground, it is necessary to determine the buried depth after the impact calculation.

4. What specifications do sewage pipes have?

The sewage pipe is the main component of the villa roof drainage system, and its function is to drain the rainwater collected in the roof gutter from the building in an organized manner. Color aluminum rainwater pipes adopt international standard sizes: 2x3 inch (51x75mm), 3xx101mm) inch rectangular sewage pipe, 3 inch (75mm), 4 inch (100mm) round sewage pipe.

5. If the sewage pipe is close to the edge of the awning, the sewage pipe can be led down from the side of the awning with an oblique elbow; If you are far away, you should wear a canopy, but you should add a sleeve.

First, you need to determine the outlet location and elevation of each pipeline, and then use this information to determine the height and location of the inspection well. During the construction process, you need to carry out the construction according to the elevation requirements on the design drawings to ensure that the height and position of each pipe meet the requirements. At the same time, you need to pay attention to the depth of the inspection well, making sure that it is deep enough to accommodate the connection and repair of the pipeline.

In the specific construction process, you need to dig out the location of the inspection well, and determine the height of the bottom of the well according to the elevation requirements on the design drawings. Then, you need to install the wellbore and Naidan manhole cover, and install the pipeline according to the outlet location and elevation requirements of the pipeline. When installing pipes, you need to make sure that the height and location of the pipes meet the design requirements and that the appropriate materials and tools are used to connect the pipes.

Finally, you need to carry out inspections and tests to ensure that there are no water leaks at the connections of the pipes and manholes, and that the water is flowing. If a problem is found, you need to repair and adjust it in time to ensure that the construction quality meets the requirements. In short, the construction of outdoor sewage inspection wells needs to be carried out strictly in accordance with the design requirements to ensure the safety and smoothness of the pipeline.

First, you need to determine the outlet and inlet heights for each pipe, as well as the elevation height of the inspection wells. You then need to calculate the elevation height of each pipe based on this data to ensure that they are all properly connected to the manhole. Next, you'll need to take measurements and markers in the field to make sure each pipe is in the correct position and height.

You can then start digging the trenches of the pipes and install the pipes to the correct depth and location. When installing pipes, you need to make sure that the pipes are sloped correctly so that the water can flow freely. Finally, you'll need to install manholes and connect each piping tassel to the correct inlet and outlet.

When installing manholes, you need to make sure that their elevation is highly sensitive and coarse, and that they have a strong and reliable connection to the pipeline. In short, the construction of the outdoor sewage inspection well to give the elevation of 4 pipelines needs to be carefully measured and calculated to ensure that the position and height of each pipeline are correct, and the slope of the pipeline and the elevation height of the inspection well should be paid attention to when installing.

Hello, it is recommended to follow the following steps for the construction of the sewage inspection well outside the indoor closure: 1According to the design drawings, determine the location and elevation of the inspection well, and excavate the corresponding pit on the site.

2.Place the prefabricated inspection well in the pit and adjust the position and levelness. 3.

Determine the elevation of the manhole cover and install interfaces on each pipe opening above the manhole. Connect the individual pipes to the interface. 4.

Install valves or shut-off valves under each pipe port for maintenance or shut-off in case of problems with the pipeline. 5.Each pipe mouth is filled with highly flowing concrete and its surface is smoothed.

6.Install the manhole cover to ensure that it can withstand the expected load and has a non-slip effect. 7.

Anti-permeation measures such as polyethylene film or stuffing glue are added around the manhole, and materials such as gravel and sand are filled in the pit before the construction is completed. It should be noted that during the construction process, we must pay attention to safety, reasonably arrange the construction process and construction personnel, and strictly abide by the relevant safety operation procedures. In addition, after the construction is completed, the construction site needs to be cleaned to ensure that the site is clean and tidy.

Can the outdoor drainage be discharged directly to the sewage reed well or should an inspection well be set up, and then discharged to the sewage well outside the room? Can the outdoor drainage be discharged directly into the sewage well, or is there an inspection well and then discharged into the outdoor sewage well?

To set up a withered inspection well, 1 the connection between the drainage pipe and the drainage pipe, should be provided with the inspection well connection; 2. Outdoor drainage pipes, except for the water flow difference of potatoes, should be connected to the top of the pipe; 3. The elevation of the top of the discharge pipe shall not be lower than the top elevation of the outdoor household pipe; 4. The deflection angle of the water flow at the connection shall not be greater than 90°. When the diameter of the drainage pipe is less than or equal to 300mm and the drop difference is greater than that, the number of losers can be limited by the angle.

Summary. Technical specification for the application of plastic inspection wells for construction quarters CECS227:2007 It is stipulated that the spacing of sewage pipes of 200 400 should be 40m, and the spacing of sewage pipes of 500 700 should be 60m.

The layout of the drainage channel should generally follow the shortest distance that the sewage should be discharged through gravity flow and the sewage treatment plant; The pipeline should be buried as parallel to the ground along the natural slope as possible to reduce the buried depth of the pipeline, and the shortest route to connect with the small flow pipe and the main pipe on a flat terrain; When the pipe depth reaches the maximum allowable value.

What is the distance between the sewage pipeline inspection well and the inspection well, and how many meters should one be set up.

Expansion and jujube information: Precautions for sewage pipeline inspection wells: Water is released into the upstream inspection wells of the sewage pipeline in the section to be tested through the nuclear vehicle of the lead shed for water transportation.

Observe the change of water level in the inspection well of Xia Huai excavation. If the water level in the downstream inspection well rises quickly, and the water level in the upstream inspection well is basically the same, it can be judged that the sewage pipeline is unblocked. Generally, the water flow velocity in the pipeline is so that the time required for the water level to rise can be estimated according to the length of the test pipe section.

If the water level in the downstream inspection well is basically unchanged or rises slowly, it can be judged that the sewage pipeline is not smooth.

Answer] :d knowledge points are empty: water supply and drainage, heating, gas engineering construction technology.

Be cautious to set up inspection wells at the connection between the discharge pipe and the outdoor drainage pipe. Generally, the distance between the center of the inspection well and the outer wall of the building is not less than 3m and not more than 10m. See textbook p74.

Blind with Hong.

The case of the hypocrisy clan is :d

This question examines the drainage system. An inspection well is set at the connection between the discharge pipe and the outdoor drainage pipe. Generally, the distance between the center of the inspection well and the outer wall of the building is not less than 3m and not more than 10m.
