What is the difference between a seepage ditch and a blind ditch ?

Blind ditch: also known as culvert, refers to the drainage and interception culvert of coarse-grained materials such as filling crushed and gravel set up in the roadbed or foundation and paved with an inverted filter layer (some of which are buried with permeable pipes). It is an underground drainage channel used to drain groundwater and lower the water table.

Seepage ditch: The large area of groundwater in the subgrade working area or below is collected in the ditch by infiltration mode, and the water is discharged to the designated place along the ditch, and this kind of underground drainage facilities are collectively referred to as seepage ditch. Since the seepage ditch has the function of collecting water flow, the seepage ditch must be "open" along the way.

The above is the definition. From the construction site, they are basically the same, but the seepage ditch is more troublesome to do. If you have to make a difference, 1

The blind ditch must have a cover plate, and the seepage ditch can be dispensable. 2.Blind ditches can also seep water from the surroundings, but mainly from one place to another (point-to-point), while seepage ditches mainly seep water from the surroundings to another place (belong to the face-to-face type).

It should be made clear that there are now permeable pipes buried in blind ditches and seepage ditches, so some people say that it is wrong to see if there are permeable pipes to distinguish them.

One of the main ones is the invisible ditch outside.

One is. Can leak into the inside of the ditch.

Blind grooves are hidden in structures. The two functions are similar.

Seepage ditches, including rock-fill seepage ditches, tubular seepage ditches, and cavern seepage ditches, are used to lower or eliminate groundwater levels.

The seepage ditch needs to construct a drainage layer, a filter layer, and a closed layer.

The function and content of blind ditch and seepage ditch are basically the same, and they are commonly found in municipal and housing construction projects.

However, it can be clearly seen that the materials used in the blind ditch and the materials used in the seepage ditch are not exactly the same, and the seepage ditch is applicable when the groundwater flow is large; The groundwater flow is small, and the seepage ditch and blind ditch are all applicable.

One of the main ones is the ditch that you can't see from the outside, and the other is the ditch that can leak inside.

Blind grooves are hidden in structures. The two functions are similar.

The explanation of the word seepage ditch is: seepage ditch shèngōu. (1) A culvert under the street to drain the ground from water.

The explanation of the word seepage ditch is: seepage ditch shèngōu. (1) A culvert under the street to drain the ground from water.

A culvert dug under the street to drain water from the ground.

2. Chinese dictionary.

In the north, the gutter hole is called the seepage ditch. Refers to a culvert built under the street to drain water.

3. Network Explanation.

Seepage ditch is a facility set up underground to lower the groundwater level or intercept groundwater. Seepage ditches are suitable for formations where groundwater is shallow or there is no fixed aquifer. Seepage ditches include rock-fill seepage ditches, tubular seepage ditches, and cave seepage ditches.
