Background

The green belt is used as an important component unit of a road section structure and has important functions of separating lanes with different functions, beautifying road landscape, preventing glare at night and the like, but the problems of water accumulation, water seepage and the like possibly caused by improper drainage treatment of the green belt can generate a larger water damage effect on a roadbed and pavement structure of a road and is also a structural weak point possibly causing diseases in the road structure. Therefore, the water prevention and drainage design of the green belt is very important in more road designs, particularly highway designs, and the traditional mode water prevention and drainage design taking the 'separation and seepage prevention' as the main design concept is formed.

In the traditional waterproof process, a method of directly paving and pasting waterproof earthwork is adopted. The effect of subgrade settlement deformation is often neglected in the traditional process. Especially collapsible loess area, because the collapsible deformation volume of loess is bigger than general road bed, the deformation of production can be bigger, and the probability that waterproof geotechnological cloth destroyed can increase a lot, and later stage restoration wastes time and energy and can cause the quality problems such as the road bed settlement of road.
