1. the filling type water and soil protection blanket has good openness and high water permeability, can ensure that an environment-friendly ecological revetment with natural river bank permeability is built, although the blanket body is filled with gravels and asphalt, the porosity can still reach more than 40 percent, not only can ensure the water exchange and regulation functions between the river bank and the river water body, but also can ensure that the root system of a plant can easily penetrate through the blanket body to grow upwards or downwards, and form good vegetation coverage effect and landscape effect on the slope surface, and the hard closed revetment can obstruct the natural exchange of river water and peripheral underground water, cut off the migration path of microorganisms in the water and destroy the environment of the laying derivation of the natural ecology.

2. Through the tests of various domestic and foreign test institutions such as river and sea university, Colorado State University (USA) and the like, the filling type water and soil protection blanket can resist the short-time flow rate of 6m/s under the condition of vegetation combination, and can replace hard slope protection materials paved at the normal water level and the parts below the normal water level to ensure the stability of slopes, banks and riverways.

The filling type water and soil protection blanket has good environmental protection performance, the raw material is polyamide (PA 6), the high polymer material cannot be naturally precipitated and absorbed, and the filling type water and soil protection blanket does not have chemical reaction with common substances in water and soil. The product passes the European Union environmental protection certification and can be used for drinking water source engineering.

The filling type water and soil protection blanket is used as a structure with good integrity and flexibility, better adapts to the local settlement of the foundation soil, can release the concentrated stress in the structure through small internal deformation, cannot generate structural damage, and avoids the problems of uneven settlement cracking and easy rapid diffusion of damage points which are possibly generated by adopting a rigid masonry structure.

5. The filling type water and soil protection blanket can be put into use after construction, and the problems that the cement masonry structure needs to be maintained for a certain period and the structure needs to be delayed in efficiency are solved.

6. Compared with the traditional scheme of mortar masonry or concrete precast blocks, the bank slope ecological protection technology of the filling type water and soil protection blanket is adopted, and the engineering cost is saved by 12-20% through rough estimation.

The above embodiments are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should be considered as not departing from the scope of the present invention.
