Description
Geomat
(3D-net, geomat, turf net and 3D-vegetation net) is a new type of slope grass protection material with three-dimensional structure suitable for sub soil and water conservation, which can effectively prevent soil and water loss, increase greening area and improve ecological environment.
Function of geomat: it can protect the land surface from the erosion of wind and rain before the turf grows, and stabilize the grass seeds at the initial stage of sowing;
After plants grow up, the composite protective layer composed of plant roots, stems, leaves, saprophytic grass system and net body can withstand the scouring of rainwater with high water level and high velocity; It can replace concrete, diamond block, masonry and other slope protection materials, and is mainly used for slope protection of roads, railways, rivers, dams, hillsides and so on.
Precautions for laying mesh cushion:
1、When using the crushed stone surface, it is necessary to consider the process of knocking soil and spraying soil first, and then hanging net and spraying.
2、When the gradient and ground perpendicularity are less than 45 °, the ordinary type shall be used, and when the gradient is greater than 50 ° and less than 90 °, the ultra-high strength type or em4, EM5 and other ordinary products with higher specifications shall be used.
3、When making slope protection materials facing the sea, it should be considered to cooperate with other auxiliary protection composite design.
4、It is only used for grass planting and slope protection on the surface, and cannot be used as deep reinforcement material.
5、When it is used for slope protection on the upstream surface of rivers, the construction should be completed three months before the rainy season to ensure that the turf slope protection above the normal water level grows firmly
