There are four types of drainage, namely: open ditch drainage, concealed pipe drainage, shaft drainage, and biological drainage.
1. Open ditch drainage.
Open ditch drainage refers to the excavation of drainage ditches at all levels to form a drainage ditch network, and the water enters the water conveyance ditch network (bucket ditch, branch ditch, dry ditch) from the field ditch network (moisture ditch, hair ditch, agricultural ditch), and finally flows into the discharge area (river, lake, sea).
2. Concealed pipe drainage.
Hidden pipe drainage, refers to the buried pipe in the ground to remove excess water in the farmland soil, reduce the groundwater level, in addition to the pipeline, there is also a ditch of a certain depth, the top cover soil or the bottom of the ditch fill with water filtration materials, and then backfill the soil, called the culvert, and use a special rat plough to penetrate out the tubular channel in the soil layer below the field surface, to drain water, called rat channel drainage.
3. Shaft drainage.
Vertical shaft drainage, referred to as well drainage, refers to the arrangement of a number of well points in the drainage area, and the well water is pumped through a pump to lower the groundwater level.
4. Biological drainage.
Biological drainage refers to the use of plants to absorb and transpirate soil water to lower the groundwater level.

The type of drainage refers to the method of moving water from one place to another. Here are the common ways to drain water:
1.Natural drainage: Natural drainage refers to the drainage of water through topography and gravity. For example, rainwater flows down the mountains and into rivers or lakes.
2.Pipe drainage: Pipe drainage refers to the movement of water from one place to another through pipes. For example, sewers and drains in the home.
3.Pumping station drainage: Pumping station drainage refers to pumping water from a low place to a high place through a pumping station. For example, pumping sewage from a low sewer to a high treatment plant.
4.Gutter drainage: Gutter drainage refers to the movement of water from one place to another through a gutter. For example, draining rainwater from drains on roads.
5.Hydraulic engineering drainage: Hydraulic engineering drainage refers to the movement of water from one place to another through hydraulic engineering. For example, water is diverted from the mountains to the plains through reservoirs and aqueducts.
The above are common drainage methods, and different drainage methods are suitable for different occasions and needs. When choosing a drainage method, it is necessary to consider factors such as the distance, height, flow rate, and water quality of the drainage.

External drainage system: refers to the rainwater drainage form in which there is no rainwater bucket on the roof and no rainwater pipe inside the building.
According to whether there is a gutter on the roof.
It can be divided into gutter drainage system and gutter drainage system.
Internal drainage system: refers to a rainwater drainage system with a rainwater bucket on the roof and a rainwater pipe inside the building.
The internal drainage system can be divided into single-bucket drainage system and multi-bucket drainage system, open internal drainage system and closed internal drainage system.

What are the drainage methods of buildings: 1. Open ditch drainage Huai swimming: mainly used for projects with small groundwater volume, or projects where the terrain is conducive to direct drainage; 2. Well point precipitation:
The precipitation of well points is divided into light well points, dredging well points, deep well points, etc. The main function is to construct large-diameter stove laughing pumping wells around the foundation pit. It is suitable for formations with large water output; 3. Blind ditch drainage:
Blind ditches are generally located around buildings or structures and are made up of sand and pebbles. The blind ditch and the excavation of the foundation pit should be combined as far as possible, and the spacing of the blind ditch should be determined according to the engineering geological conditions.

1. Open ditch drainage. Excavate drainage ditches at all levels to form a drainage ditch network, and water enters the water conveyance ditch network (bucket ditch, branch ditch, dry ditch) from the field ditch network (moisture ditch, hair ditch, agricultural ditch), and finally flows into the discharge area (river, lake, sea).
2. Concealed pipe drainage. Buried pipes are buried underground to remove excess water from farmland soil and reduce groundwater levels; In addition to pipelines, there are also ditches of a certain depth, covered with soil or filled with water filtration materials at the bottom of the ditch, and then backfilled, called culverts; There is also a special rat passage plough that penetrates the tubular passage in the soil layer below the field surface to drain water, which is called rat channel drainage.
3. Shaft drainage. Referred to as well drainage, a number of well points are arranged in the drainage area, and well water is pumped through a pump to lower the groundwater level.
4. Biological drainage. The absorption and transpiration of soil moisture by plants are used to lower the groundwater level.

The decoration of the bathroom is also very important in home decoration, it is the place where we wash off the dirt on the body, if it is not handled well, if the sewer is blocked and leaking in the future, it will not only affect the quality of our home life, but also seriously affect our mood.
And the bathroom drainage method summarizes three categories for you! Including: different layer under the drainage method, the same layer caisson drainage method, the same layer after the drainage method!
1. Drainage method under heterolayer board:
For a long time, China's toilet drainage design scheme adopts heterolayer plate drainage, that is, the drainage pipe of sanitary appliances is laid on the upper part of the lower toilet. The specific method is to lay the drainage branch pipe of each appliance in the toilet vertically through the floor slab to the upper part of the toilet on the lower floor, and then connect the drainage branch pipe of each sanitary appliance with a horizontal branch pipe and discharge it to the sewage standpipe. In this way, the drainage branch pipes of the upper toilet are all in the upper part of the toilet of the lower household, and all the hidden dangers of water leakage are left in the home of the lower household.
2. Which noisy type of caisson drainage party on the same floor:
The structural slab of the toilet is sunk more than 350mm, and the sanitary ware drainage pipe is laid in the caisson (i.e., on the structural plate), and then discharged to the sewage riser. After the pipeline is laid, the caisson is backfilled to the building elevation with light building materials (fly ash, ceramsite concrete, coke ballast, etc.), and the caisson backfill layer is secretly laid with side drains connected to the sewage ventilation pipe. In this way, the toilet drains are not guessed to be on the structural board and have no connection with the residents on the lower floor.
3. Drainage method after the same layer:
The structural slab of the toilet sinks 50-100mm, the floor drain adopts the special floor drain for drainage on the same floor, the toilet adopts the rear drainage type, and the horizontal branch pipe of drainage is parallel to the wall and laid close to the ground on the board to discharge to the sewage standpipe. Due to the small sinking size of the bathroom, the horizontal drainage branch pipe belongs to the open laying, and it is necessary to use lightweight plates to close the exposed drainage pipe, that is, the wall is thickened by 120mm from the ground 1m section to achieve the purpose of closing the horizontal drainage branch. In this way, the toilet drains are all on the board, and the thickened wall part is only 1m high, which can be placed with ornaments to save less space.
The drainage methods under the heterolayer board, caisson drainage on the same floor and drainage after the same layer have their own advantages and disadvantages in actual use, and each has its own scope of application. The scope of use of the same layer caisson drainage and the same layer drainage method will be more and more extensive, and the development prospect is obviously better than that of the drainage method under the heterolayer plate.

What are the types of roof drainage? As follows: Hello, dear, roof drainage is divided into two ways: organized drainage and unorganized drainage.
1) Unorganized drainage, also known as free falling, is to extend the roof panel out of the wall to form an eaves, and the rainwater on the roof falls freely through the eaves. Unorganized drainage is easy to wet walls, doors and windows, so it is only suitable for.
Second- and three-storey houses or minor buildings. (2) Organized drainage is to divide the roof into a number of drainage areas according to different slope directions, so that the rainwater is concentrated in the roof gutter or gutter, and then the rainwater is directed to the ground drainage system through water diversion devices such as downspouts and downspouts. According to the downspouts in indoor and outdoor, they are divided into internal drainage and external drainage.
The water diversion device for roof drainage includes iron sheet product drainage, asbestos cement product drainage, cast iron product drainage, glass fiber reinforced plastic product drainage, hard polyvinyl chloride (PVC) product drainage, etc.
You can dig a trench to drain the water, you can use a pump to drain the water, dig a pit at the deepest point of the water and pump it to pump water.
High-rise buildings, copper walls and iron walls, crumbling, crooked, dangerous, brilliant, magnificent, magnificent.
Pump dredging method. When the small pipe is blocked, you can plug the hose of the pump into the drain pipe, seal the drain, and then put in enough water to quickly pump air into the sewer, and the pipe can be dredged. Soda and vinegar dredging method. >>>More
