[0028] 1. Coconut fiber vegetation blanket; 2. Seed layer; 3. Slope; 4. Planting soil; 5. Anchor. DETAILED DESCRIPTION

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a coconut fiber vegetation mat for protecting the revetment of the present embodiment comprises a plurality of coconut fiber vegetation mats 1 arranged on the slope 3 of a river, a mountain or a terrace, wherein the plurality of coconut fiber vegetation mats 1 are overlapped in sequence along the extension direction of the slope 3, the coconut fiber vegetation mats 1 are anchored on the slope by anchors 5, a seed layer is sprinkled on the coconut fiber vegetation mat 1, a layer of planting soil 4 is covered on the seed layer, and a seed layer is sprinkled on the surface of the planting soil 4.

[0031] like Figure 1 As shown, the multiple coconut fiber vegetation blankets 1 of this embodiment are overlapped in sequence in a manner that the upstream coconut fiber vegetation blanket 1 presses the downstream coconut fiber vegetation blanket 1 along the slope. The method of overlapping multiple coconut fiber vegetation blankets in a manner that the upstream coconut fiber vegetation blanket presses the downstream vegetation blanket along the slope is convenient to overlap, beautiful, and has strong resistance to wind, rain, water flow, etc.

[0032] Preferably, the overlapping width of two adjacent coconut fiber vegetation blankets 1 is 8 cm to 12 cm, and can be 9 cm, 10 cm, 11 cm, etc.

[0033] Optionally, the bottom of the coconut fiber vegetation blanket 1 has a seed layer 2. Multiple layers of green plants can be arranged on the slope, which is beneficial to the stability of the slope.

[0034] like Figure 1 As shown, in this embodiment, the overlap of two adjacent coconut fiber vegetation blankets 1 is anchored by anchoring pieces 5. Anchoring by anchoring pieces is conducive to the stable anchoring of the coconut fiber vegetation blanket on the slope.

[0035] Preferably, at least one anchor 5 is anchored within every 2 to 3 square meters of the slope 3 .

[0036] A preferred solution of this embodiment is that the top of the slope 3 has a levee crest, the bottom of the slope 3 has a levee foot groove, and the upper and lower ends of the coconut fiber vegetation blanket 1 extend respectively and are fixed on the levee crest and in the levee foot groove through anchors 5. This prevents the coconut fiber vegetation blanket from being lifted up on the levee crest or the levee foot groove, and enables the coconut fiber vegetation blanket to be stably anchored in the levee crest and the levee foot groove.

[0037] like Figure 2 As shown, the anchor 5 of this embodiment is a U-shaped structure.

[0038] Specifically, the width of the U-shaped structure is 4-6 cm, and 5 cm can be selected. The length of the U-shaped structure is 35-50 cm, and 42 cm, 45 cm can be selected.

[0039] Among them, the coconut fiber vegetation blanket 1 is an environmentally friendly plant covering material made of natural materials, mainly used in ecological restoration and greening projects. It is mainly made of natural materials such as coconut shell fiber and straw through special processing and weaving, and has the characteristics of environmental protection and degradability; the coconut fiber vegetation blanket is composed of two layers of reinforced mesh and the middle plant fiber mesh, and is a degradable blanket material processed by composite quilting technology. It is an ideal slope protection greening grass blanket for river ecological slope construction, which can effectively play the role of slope protection and greening. The coconut fiber vegetation blanket is made of coconut fiber and crop straw (such as straw) through special processing and weaving. The material of the coconut fiber ecological blanket is relatively dense, the fiber thickness is adjustable, and the degradation time is as long as 3-5 years; while the straw fiber ecological blanket is mainly made of crop waste such as wheat straw and straw, and the degradation time is short, usually completing degradation within 6 months to one year. The material and three-dimensional structure of the coconut fiber vegetation blanket can reduce the evaporation of surface water. At the same time, it absorbs and stores water by itself, which is more water-saving than other greening projects, and effectively reduces the cost of irrigation and maintenance. The coconut fiber vegetation blanket uses plant fiber as a carrier, has good degradability, and is pollution-free to the environment. After laying, it can effectively prevent the damage to the slope by adverse factors, and play a physical protection role for the slope and plants. The coconut fiber vegetation blanket can effectively change the temperature and humidity of the slope, accumulate fertilizer and retain moisture, and improve the growth conditions of plants. It is especially suitable for dry and barren areas. The coconut fiber vegetation blanket is packaged in rolls, which is convenient and fast to construct, simple to maintain, and greatly reduces the cost of the project. The upper and lower reinforcement nets and the middle fibers of the coconut fiber vegetation blanket can absorb the energy generated by the impact of rainwater, reduce the scouring force of rainwater on the land surface, and prevent soil particles from moving with the water flow. The coconut fiber vegetation blanket plays an important role in the field of ecological restoration and greening. It can be used in scenes such as the repair of highway slopes, exposed mountains, protection of river slopes, and reclamation of mining areas. In addition, coconut fiber vegetation blankets can also be used in greening projects in urban roads, parks, green spaces, roof gardens and other places to beautify the environment and improve ecological quality.

[0040] The coconut fiber vegetation blanket of this embodiment can be used to protect the revetment, and can be used for flexible slope protection of roads, railways and river slopes. It is not only easy to construct and has good soil consolidation effect, but also can be carried out simultaneously with the roadbed construction. Different plant communities are used to consolidate the soil and protect the slopes, and the slopes are protected in real time. The construction cost is much lower than the traditional method, and the later maintenance cost is almost zero. The coconut fiber vegetation blanket can be applied to various urban greening. It not only has a fast construction speed, but also has a high survival rate and strong selectivity. Different grass species can be selected according to different soils and different uses, and it does not require a large amount of water, which fundamentally solves the current water use situation and saves a lot of costs.

[0041] This embodiment also provides a construction method for protecting the revetment with the coconut fiber vegetation blanket, comprising the following steps:

[0042] S1, clearing stones and plant roots on the slope 3 of the river, mountain or terrace, and filling the low-lying areas on the slope 3;

[0043] S2, multiple coconut fiber vegetation blankets 1 are laid longitudinally in sequence along the extension direction of the slope 3 (if they are laid along the river bank, they are installed vertically along the coastline), and multiple coconut fiber vegetation blankets 1 are overlapped in sequence along the slope 3 in the manner of upstream coconut fiber vegetation blanket 1 pressing downstream coconut fiber vegetation blanket 1, and anchored with anchors 5; specifically, during installation, the length of the slope and the depth of the grooves at both ends are measured, and the coconut fiber vegetation blankets of corresponding lengths are calculated and cut, and the blanket body is moved to the corresponding position, unfolded along the slope and adjusted in position (pay attention to distinguish the front and back of the blanket body), and the coconut fiber vegetation blanket is placed in the groove at the top and foot of the embankment and fixed with anchors (the spacing between anchors is 1m), and one anchor is fixed every 2-3 square meters at the other slope positions under normal slope conditions.

[0044] S3, after laying and anchoring, sow a seed layer on the surface of the coconut fiber vegetation blanket 1, and cover it with a layer of planting soil 4. After the planting soil 4 is compacted, it evenly fills the coconut fiber vegetation blanket 1 and overflows the preset height of the coconut fiber vegetation blanket 1; sow local grass seeds or seed-sown flowers with well-developed root systems on the surface of the coconut fiber vegetation blanket; and cover it with a layer of planting soil, and then sow vegetation grass seeds once more on the surface of the planting soil layer. After laying, it should be quickly anchored and covered with planting soil. The thickness of the covering soil is about 10cm. The best effect is to evenly fill the blanket body with a little overflow after the ground is compacted.

[0045] S4, non-woven fabrics are covered on the slope surface of the construction slope 3 to protect the vegetation during the germination period; the seed layer needs to be watered and maintained for one to two weeks after sowing to ensure the moisture required for the germination period; when watering, excessive water flow should be avoided to damage the uniform distribution of seeds. Different planting methods can also be selected according to design requirements and specific project conditions to achieve a three-dimensional hydraulic effect.

[0046] Specifically, first level the slope surface, clean up the debris on the slope, backfill and tamp the low-lying areas to ensure a smooth slope, lay the coconut fiber vegetation mat from bottom to top, so that it is in full contact with the slope soil, use U-shaped steel bars as anchors to fix the coconut fiber vegetation mat, and place stones to weigh it down according to the site conditions, then cover the surface with a thin layer of soil, plant grass immediately, and finally cut live plant branches. Consider leaving a margin at the top and end of the vegetation mat and use stones to make a smooth transition.

[0047] The coconut fiber vegetation mat constructed on the slope is divided into four layers. The first layer is the natural soil of the slope. The second layer is the seed layer of the coconut fiber vegetation mat. Grass seeds such as bermudagrass, bahia grass, large-leaf oil grass, peanut and shrubs such as bougainvillea and azalea can be selected; the third layer is the coconut fiber vegetation mat, which not only strengthens the embankment, but also provides an environment for vegetation growth and can be quickly degraded; the fourth layer is 10cm planting soil, which provides a growth environment for plant seeds; the coconut fiber vegetation mat is fixed with U-shaped steel bars (round steel).

[0048] The construction method of this embodiment has a fast construction speed, a high survival rate, and strong selectivity. Different grass species can be selected according to different soils and different uses, and no large amount of water is required, which fundamentally solves the current water use situation and saves a lot of costs.
