Description

Technical Field

[0001] The utility model relates to the technical field of anti-landslide mechanisms for construction, in particular to a plant fiber blanket suitable for highway slopes. Background Art

[0002] At present, the soil quality of highway slopes is mainly sandy soil, which is easy to construct but has the possibility of overall landslide.

[0003] Landslide refers to the natural phenomenon that the soil or rock on the slope slides down the slope as a whole or in a dispersed manner along a certain weak surface or weak zone under the action of gravity due to factors such as river scouring, groundwater activity, rainwater soaking, earthquakes and artificial slope cutting. The moving rock (soil) is called a displacement body or sliding body, and the underlying rock (soil) that has not moved is called a sliding bed.

[0004] Plant fiber blankets are made of advanced production equipment and process technology, with natural fibers such as straw as the base, together with high-quality grass seeds, nutrients, special paper, shaping nets and other materials (depending on the purpose), and are processed in one go on a large production line. Spreading plant fiber blankets on the surface can resist water erosion, wind erosion, solidify the surface, prevent soil and water loss, and store surface moisture. They can be widely used in sandy soil, hillsides, rivers, mining reclamation, railways, roadbed slope ecological protection, gardens, airports, football fields, golf courses, roof gardens, etc.

[0005] However, for low-fill sections with a range of 3≤H≤7, after the construction of traditional plant fiber blankets, it is difficult to cope with the problem of overall slope sliding caused by rainfall. Therefore, in order to solve the problem of slope water damage, it is necessary to optimize the structure of the plant fiber blanket and improve the tensile strength and fixing strength of the plant fiber blanket to prevent slope soil landslides. Utility Model Content

[0006] The utility model provides a plant fiber blanket suitable for highway slopes to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A plant fiber blanket suitable for highway slopes, comprising a plant fiber blanket main body, wherein the plant fiber blanket main body is composed of two sets of polypropylene fixed nets, a plant straw layer and a non-woven fabric supporting layer, wherein the two sets of polypropylene fixed nets are distributed at the upper and lower ends, and the plant straw layer and the non-woven fabric supporting layer are located between the two sets of polypropylene fixed nets;

[0009] The polypropylene fixed net is composed of a polypropylene net, a galvanized iron wire net and a fixed card slot.

[0010] A further improvement of the technical solution of the utility model is that the density of the galvanized wire mesh in the polypropylene fixed mesh is 4 pieces / m2, the galvanized wire mesh is 20cm*20cm, and the fixed card slot is located at the galvanized wire mesh.

[0011] A further improvement of the technical solution of the utility model is that the base of the fixed card slot is made of iron, and the fixed card slot is welded to the galvanized iron wire mesh.

[0012] The further improvement of the technical solution of the utility model is that: a plurality of groups of long bamboo sticks are arranged in an array at the fixed card slot, the center size of the fixed card slot is consistent with the long bamboo stick, and the size of the long bamboo stick is 35cm*2.5cm. Its function is to increase the length of the anchor nail, increase the fixing strength of the plant fiber blanket, and effectively use the tensile force of the plant fiber blanket to prevent soil landslides caused by rainfall.

[0013] The further improvement of the technical solution of the utility model is that the plant straw layer is made of a mixture of degradable rice straw and coconut shreds, and the non-woven fabric supporting layer is composed of non-woven fabric and soil adhesive. The soil adhesive on the non-woven fabric supporting layer is to increase the friction between sandy soil particles, reduce the water permeability of the slope, and reduce the problem of soil loss.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] The utility model provides a plant fiber blanket suitable for highway slopes. After artificially brushing the slope, plant grass seeds are sown, and the plant fiber blanket is subsequently laid. It is fixed with long bamboo sticks at the fixing slots, and the remaining parts can be fixed with U-shaped nails or T-shaped bamboo sticks, so as to avoid the possibility of overall landslide during construction, solve the problem of water sections on the slope, optimize the existing plant fiber blanket structure, and improve the tensile strength and fixing strength.
