Which code requires that the drain should not have stagnant water?

In construction engineering, the drainage system is a very important part, its role is to discharge rainwater, sewage, etc. to the designated place to ensure the normal use of the building. As part of the drainage system, the design and construction of the gutter must comply with the relevant codes and standards to ensure its proper operation and safety.

According to the Code for Design of Building Drainage (GB 50015-2019), the drainage ditch should be designed to be free of water accumulation to ensure smooth and hygienic drainage. The design of the gutter should take into account factors such as the amount of drainage, slope, section shape, etc., to ensure that the water in the gutter can flow quickly and will not be trapped in the gutter.

However, in actual construction, there is sometimes water accumulation in the drainage ditch. This may be due to unreasonable design of drainage ditches, non-standard construction, untimely maintenance, etc. If the drain is waterlogged for a long time, it will not only affect the drainage effect, but also breed bacteria, mosquitoes and other hygiene problems, and even lead to damage and leakage of the drain.

Therefore, in order to ensure the proper functioning and safety of the gutters, the drainage system in the construction project must comply with the relevant codes and standards, and the gutters should be designed to be free of water accumulation. If there is water accumulation in the gutter, measures should be taken in time to clean and maintain it to ensure the smooth flow and hygiene of the gutter. At the same time, the design, construction and maintenance personnel of the construction project should also have the relevant knowledge and skills to ensure the proper operation and safety of the drainage system.

Hello, the drawing specifications generally say so, but in fact it is impossible to do without, it is recommended to master the slope when constructing. Thank you!

Gutters are not counted as floor area. The floor area refers to the projection area of the building on the ground, including all the rooms, corridors, stairs, balconies, and other spaces inside the building. Whereas, a gutter is a facility built for drainage and is not part of the internal space of the building, so it is not included in the floor area.

Drainage ditches are very important facilities in building design and construction. It can effectively drain rainwater and sewage around the building, ensuring the stability and safety of the building. The design section of the drainage ditch and the construction of the car need to follow the relevant codes and standards to ensure its function and quality.

Floor area is an important indicator in the sale and appraisal of a home. Buyers and appraisers need to accurately calculate the square footage to determine the value and ** of the home. Therefore, the drainage ditch is not counted as the construction area, and it has no impact on the value and ** of the house.

In conclusion, gutters are not considered floor area, but they play an important role in building design and construction. Architects and construction crews need to design and construct gutters to ensure their function and quality.

The calculation method of the floor area is stated in the budget base price (fixed amount), and the drainage ditch is only a measure during construction, and the floor area cannot be calculated.

The gutter does not count the floor area, and the list and quota are the same

A gutter is a facility used to drain water, usually used in places such as cities, roads, buildings, farmland, etc. The main function of drainage ditches is to collect and discharge rainwater, groundwater, sewage carrying water, etc., to keep the environment clean and safe.

There are many types of gutters, which can be divided into curb gutters, concrete gutters, limestone gutters, plastic gutters, etc., depending on their use and location. Among them, curb gutters are the most common one, which are usually located on both sides of the road and are used to collect rainwater and sewage on the road surface, preventing water from soaking the road surface and affecting traffic safety.

The design and construction of drainage ditches needs to consider a variety of factors, such as topography, rainfall, soil type, water velocity, etc. When designing, it is necessary to determine the length, width, depth, slope and other parameters of the drainage ditch according to the actual situation to ensure that the drainage effect is good. During construction, it is necessary to pay attention to the material selection of the drainage ditch, the construction quality, the setting of the drainage outlet, etc., to ensure the stability and durability of the drainage ditch.

Apart from gutters, there are some other facilities for drainage, such as rainwater harvesting systems, rain gardens, rainwater barrels, etc. These facilities can effectively collect and utilize rainwater, reducing the pressure on urban drainage and adding greenery to the city.

In conclusion, drainage ditches are an indispensable part of urban construction, which can effectively collect and discharge rainwater, groundwater, sewage, etc., to keep the environment clean and safe. In the future of urban construction, we need to pay more attention to the design and construction of drainage facilities to meet the challenges brought about by climate change and urbanization.

Underground drainage ditches belong to structures, because structures generally refer to places where people do not directly carry out production verification and living activities.

A drainage ditch refers to a ditch that diverts water from side ditches, interception ditches, and low-lying areas near roadbeds, crops, and dwellings to ditches other than roadbeds, crops, and residential areas. The design of the drainage ditch is based on the engineering layout and engineering standards of the drainage system, the depth and spacing of the drainage ditch in the field are determined, and the flow, water level, section size and engineering quantity of the drainage excavation ditch and buildings at all levels are analyzed and calculated.

Drainage ditches belong to municipal works. First, if it is a drainage ditch in the city, it should be a municipal project. Second, if the drainage ditch in the village of Xiangbeisui should be a construction project.

There's a difference. There are drainage pipes in the city, including sewage pipes and rainwater pipes, and there is no chaos in the countryside, and sewage and rainwater flow down the streets.

Dear, your stool is good, I am happy to answer your <>

Answer: The drainage ditch is indirect drainage, and the ground drainage ditch that is not often drained should take measures to waterproof and seal the drain, and generally take the indirect drainage (water replenishment) method into the drainage ditch at regular intervals according to the climatic conditions. The pool (tank) drainage outlet has outdoor rainwater inspection wells and basement drainage ditches (should"Indirect"drainage), roof rainwater gutters, etc., their excretion capacity is large and small, and cannot be treated equally.

Drainage ditches are generally laid at both ends or lower ends of slope interception ditches to eliminate surface runoff that cannot be accommodated by interception ditches. The terminus of the gutter is connected to a cistern or a natural drain. 2. The specific drop of the drainage ditch on the slope surface is determined according to the location of its drainage place (reservoir or natural drainage channel), when the position of the drainage outlet is at the foot of the slope, the drainage ditch is roughly arranged orthogonally with the slope contour line; When the position of the drainage ditch is on the slope vertical and rough remaining surface, the drainage ditch can be basically laid along the contour line or diagonally with the contour line.

All kinds of laying must be prepared with anti-scouring measures (turf or stone lining). 3. The drainage ditches at both ends of the terraced area are generally arranged orthogonally with the slope contour line, and are roughly in the same direction as the road at both ends of the terraces. Generally, soil drainage ditches should be set up in sections to fall water.

The longitudinal section of the drainage ditch can be consistent with the large section of the terraced area, with the width of each field as a horizontal section, and the height of each field as a water fall, and anti-scouring measures should be taken at the water fall (paved with turf or stone lining).

Summary. Further information: The distance between the laying of sewer pipes and private houses should meet the following requirements:

When the pipe diameter is less than or equal to 200mm, the horizontal spacing is 15m, when the pipe diameter is greater than 200mm, it should be greater than or equal to 2 5m；The horizontal spacing between the drainage pipe and the building foundation should be greater than or equal to 2 when the buried depth is shallow than the building foundation

According to the overall plan, the layout of roads and buildings, the elevation of the terrain, the whereabouts of sewage and rainwater and other factors, in accordance with the principle of the shortest pipeline, the smallest buried depth, and as much as possible self-draining. 2. Drainage pipes should be laid in parallel along the perimeter of roads and buildings to minimize the intersection of each other and other pipelines. 3. The pipeline should not be on the sidewalk or under the grass on the outside of the road.

Hello, the distance between the drainage ditch and the building is 80 cm - 1 meter can be Ha Extended information: The distance between the laying of the sewer pipe and the house should meet the following requirements: when the pipe diameter is less than or equal to 200mm, the water stuffy flat spacing is 1

5m, when the pipe diameter is greater than 200mm, it should be greater than or equal to 2 5m；The horizontal spacing between the drainage pipe and the building foundation should be greater than or equal to 2 when the buried depth is shallow than the building foundationAccording to the overall plan, the layout of roads and buildings, the elevation of the terrain, the whereabouts of sewage and rainwater and other factors, in accordance with the principle of the shortest pipeline, the smallest buried depth, and as much as possible self-draining.

2. Drainage pipes should be laid in parallel along the perimeter of roads and buildings, and try to reduce the intersection of each other and other pipelines. 3. The pipeline should not be on the sidewalk or under the grass on the outside of the road.
