Encourage Vegetation on Gentle Non-soil Slope
As
Hong Kong is geographically hilly region, most of the territories development is
associated with the slope stabilization and protection work. Shotcrete is the
most commonly used methodologies to cover the soil slope and prevent surface
erosion. Therefore, numerous
natural vegetation woodland slopes are gradually reduced, environmental
pollution is magnified, the ecology system is damaged whereas the macro climate
is affected. In 1998, Toyo introduced an advanced slope greening technique from
Japan. By spraying the organic fibrous mulch material on steep slope and provide
reliable planting medium, it is firstly named as Hydromulching in Hong Kong in
the project of Smithfield Road, Hong Kong, contract no. HY/94/20.
Three
important elements of Hydromulching are turf reinforcement mat, fiber soil and
erosion control mat. Turf reinforcement mat is a 3-dimensional PVC coated
rhombic galvanized wire mesh. The function of the mat is to reinforce the
cohesiveness of fiber soil over the slope. Fiber soil is the organic mulch
materials, which is the mixture proven to be gas permeable, strong power in
retaining water and have long lasting nutrient for the well establishment of
grass. The bio-degradable erosion control mat making up by coconut fiber, which
is an environmental friendly material, with low heat absorption rate and high
moisture retaining capacity.
The system does allow the vegetation itself to create an equilibrium environment to grow and encourage primary and secondary germination of the vegetation on steep soil slope with slope gradient up to 75o or gentle non-soil slope with slope gradient up to 60o.
