The geotextile mat three dimensionalis a new geosynthetic material with three-dimensional structure suitable for soil and water conservation, which can effectively prevent soil erosion, increase green area and improve ecological environment.

1) geotextile mat three dimensionalcan replace concrete, asphalt, riprap and other slope protection materials, mainly used for highway, railway, river, embankment, hillside and other slope protection.

2) The geotextile mat three dimensionalcan protect the land from wind and rain before the turf grows.

3) The composite protective layer formed by geotextile mat three dimensionalcushion plants can withstand the scour of high water level and high velocity.

4) Geotextile mat three dimensionalcan greatly reduce the project cost, which is only 1 / 7 of the concrete slope protection and dry masonry slope protection, and 1 / 8 of the mortar block stone slope protection.

5) Due to the use of polymer materials and UV anti UV stabilizers, the geotextile mat three dimensionalhas high chemical stability and no pollution to the environment (the degraded mesh pad can leave no trace in the soil two years later).

6) The construction of geotextile mat three dimensionalcushion is simple, and it can be constructed after the surface is leveled.

Geotextile mat three dimensionalfor slope surface leveling: in order to ensure the close combination of geotextile mat three dimensionaland slope surface, the slope surface after acceptance shall be carefully leveled manually, and all debris, plants, garbage and other obstacles that may cause lifting of the net pad shall be removed.

Improvement of geotextile mat three dimensional: the slope with poor soil filling conditions and unfavorable to grass growth shall be backfilled and improved with the thickness of 2-5cm, and wetted with water to make the slope naturally settle to stability.

Setting out of geotextile mat three dimensional: after finishing the beach surface, first set out the position of each volume of reinforced three-dimensional steel wire mesh mat, and drive the setting out pile to fix it.

The cutting length of the geotextile mat three dimensionalis 300cm longer than the slope surface. It is laid along the slope. When laying the mesh, the mesh shall be closely attached to the slope surface as much as possible to prevent suspension. When laying, the mesh shall be kept flat without wrinkles. The mesh shall be overlapped and lapped with a width of 10cm. At the same time, it is necessary to ensure that the upstream reinforced 3D wire mesh pad is laid on the downstream reinforced 3D wire mesh pad. The upper end of the geotextile mat three dimensionalshall be pressed into the stone wave wall, and the lower end shall be pressed into the stone concrete toe protection. The three-dimensional net is fixed by U-nails, and then filled and compacted. The overlapping parts between the mesh pads shall be made into "U" shaped nails with no less than φ 8 steel bars for anchor nails, so as to connect them as a whole. During the construction, it is forbidden to drive vehicles, people or machinery on the geotextile mat three dimensional.

It is better to cover the soil with fertile topsoil. For the poor thin soil, it should be filled with organic fertilizer and chemical fertilizer to improve its fertility. In order to ensure that the covered soil is full of mesh bags and does not press the bags, it should be filled in layers and times, and watered until the mesh bag layer is not exposed.

Grass seed should have good resistance to adversity. It can be sown manually or hydraulically. After being sown manually, it should be sown with 2-3cm fine-grained soil. During rainy season construction, it should be covered with non-woven cloth to promote the germination and growth of grass seed, and it can also be covered with straw and straw woven mat

Geotextile mat three dimensionalearly maintenance

The geotextile mat three dimensionalslope protection should pay attention to watering maintenance, and the maintenance period depends on the growth of slope vegetation, generally no less than 45d; it should spray broad-spectrum chemicals regularly to prevent the occurrence of various diseases and pests in time; after the germination of grass seeds, it should timely carry out supplementary sowing in the sparse grass free area. The geotextile mat three dimensionalis widely used, and the unique production process makes the product structure more scientific and reasonable.
