Under the action of pressure, water can enter the lower mixture from the upper mixture through the communication gap of the mixture itself. However, after the interlayer of geotextile is installed, after the filament nonwoven geotextile factory pr...

1. Is there any influence from the spread of the film? After the film is laid, the infiltration line before the film rises slightly, while the infiltration line after the film decreases significantly. At the same time, the constant water headline ...

Soil erosion is a major global production and environmental problem. The most serious soil erosion is the steep slope of bare soil. In highway construction, especially highway construction, a large number of exposed steep slopes are often formed, ...

The connection between the test section and the conventional section appeared earlier, indicating that there are still weak sections in the variable cross-sections of the two structural layers where only geotextiles are laid, and special treatment...

Grouted masonry, concrete, or film can be used for canal seepage prevention. Kangping County is located in a severe cold area, with deep freezing and large frost heaves. If a rigid anti-seepage structure is adopted, a large number of replacement l...
