Three-dimensional vegetation earth-fixing mat

 

 

1. Three-dimensional vegetation earth-fixing mat product characteristics

Three-dimensional vegetation earth-fixing mat by the multi-layer plastic bump networking and two-way network stretching plane, and the transfer point by the hot-melt adhesive and after the formation of a stable three-dimensional structure of the network. Uneven surface appearance, flexible loose material, leaving more than 90% of the space charge fields of soil and sand. The bottom two-way network has a tensile elongation of the low strength of high character, plays a down-slope to prevent. The plant roots from the vegetation of the entire network in a comfortable cushion in a balanced manner through in-depth on the ground floor up to 0.5-2m deep. This vegetation, soil and the three network pad to form a strong composite inlay mechanical lock system, so as to protect the slope.

2. The role and purpose

1) The role of the homeland is very clear. Experiments show that there is no turf ago, when the slope angle to 45oC, three-dimensional network of vegetation mats of soil-block rate as high as 97.5 percent, when the slope is 60oC, the block rate as high as 84%, even though slope Oblique angle for the lead at right angles, can still block rate as high as 60%. In other words, this should not or can not hold the vertical slope on the map, due to the existence of the mat, can remain in block 60% of the earth to live, three-dimensional network of vegetation mats with excellent soil solid results, which is far better than flat net.
2) Grown into sod did not before; you can protect the surface from wind and rain erosion.
3) Garnish grass, grass seed can be firmly maintained evenly distributed on the slope, the wind and rain from the destruction and loss.
4) grown into sod, soil and mat and the three combined to form a strong mechanical lock embedded system-level winds and heavy rain to prevent attacks and withstand the high water level, the impact of traffic, instead of concrete, mortar stone tablets And so on as a permanent slope protection layer.
5) Using a black pad network will help to absorb a large number of thermal energy, increase temperature to promote seed germination and extend the growing season of plants.
6) Due to the rough surface, so that the wind, currents in the mat surface of countless small eddy, can play a role in energy dissipation, to bring the deposition in net in the pad.
7) The use of PE polymer additives and carbon black, and its chemical stability and reliable, life expectancy in the ground for up to 50-100 years in the entire transport and water conservancy project design life, to play such a complex mechanical lock system embedded role (For special needs, can-degradable plastic mat in the next few years will be in the soil disappeared, Leave No Trace).
8) Green vegetation to absorb motor vehicle exhaust, and can beautify the landscape, protecting the environment, Green Road, along the railway line.
9) The construction is simple, smooth surface, you can work.

4.Construction method

    When constructed, sticks can be used to penetrate the roll of net cushion and duil out the net cushion. You should nail around the net cushion with bamboo nail or wooden nail and plastic nail. The range between nails should be 30cm. 10 nails /per square meters. The length of nail is normally 15cm (above the surface), nail length should be lengthen if the soil is loose. When constructed in slope roads, the nails in upward slope should be longer than the downward slope. Net cushion should be kept flat with more nails needed if the earth surface is complicated and varied. Joint parts should be at least 2cm. nails in joint parts should be nailed more to keep the net cushion tight without space. The shape of the nail and the upper end width of the nails should be twice as the net diameter to keep the net cushion vertical. Grass seeds are planted depending on the greensward condition. Grass seed selection should accord with the local climate. Long roots and small bushes growing many years should be the best choice. The depth of grass seed planting should be in net cushion to take the effects of better protection. After the grass seeds are planted. The surface soil covering will cover the net cushion to avoid the net cushion from sunlight so as to extend the usage time, but will be helpful for the grass buds to come and grow up. After the grass seeds are planted, water percentage in soil layer should be 40%-50%.  When the net cushion is paved in the upper end of slope, the joint part in the direction of lengthway should be angled 60 0C underneath the surface 30cm.The bottom end of the slope should have 50cm flat surface. A storage water channel should be dug out 20cm away from the net cushion for convenience to irrigate because the upper part of the slope contains more water than the bottom part.

 Pave work is the key point among the entire projects (when it is used on the slope).The pave work should be done 3-4 months before the rain season so that the grass can have enough time to grow.
