A kind of planting mesh blanket for slope repair and slope repair method

Abstract

The invention discloses a plant-growing meshwork carpet for slope restoration and a slope restoration method. The plant-growing meshwork carpet comprises a fine grid linen net surface layer, a seed layer, a coconut net geotechnical grid chamber and a fine grid linen net bottom layer; plant-growing matrix fills in the coconut net geotechnical grid chamber; all parts are fixed into a carpet-shaped coil through degradable fibers. The plant-growing meshwork carpet is high in flexibility, and can be bent at random to be adapted to various uneven slopes; the seed layer can be collocated at random as requirement, the rooting and sprouting effects are good, the slope entironment can be improved within a short period, the ecological benefits are increased, and moreover, the benefiting period is long; the manufacturing cost is low, the materials are easily obtained, the maintaining cost is low, and thus the economic benefit is obvious, and a good landscaping effect is achieved.

Description

technical field [0001] The invention relates to a planting net blanket for slope repair and a slope repair method. Background technique [0002] With the rapid development of the economy, the construction of highways, railways and other traffic roads across the country, the excavation of mines, and the development of villas in the middle of the mountain by real estate developers have damaged the ecological environment of the mountain, forming a large number of exposed slopes and causing damage to the original surface vegetation. , soil erosion, debris flow, landslides and other environmental problems, so exposed slopes have become a concern in the field of ecological restoration. [0003] At present, the commonly used methods for slope restoration mainly include: planting green plants, hanging nets and spraying foreign soil, digging ditches and planting grass, planting grass in geocells, placing vegetation bags / blankets, etc., all of which have some shortcomings: [0004] P...

AI Technical Summary

Problems solved by technology

[0008] (1) Non-woven fabric as seed cushion: the grass roots are short and shallow, and it is difficult to pass through the non-woven fabric to take root on the slope, which affects its rooting and planting;

[0009] (2) Plastic woven net or nylon fiber net: it has a certain waterproof and evaporation effect, but because the material does not absorb water, it also prevents precipitation from entering the bag, and the damage is serious after being exposed to wind and sun, and it is not good for later use;

[0010] (3) Planting bags / blankets such as comprehensive Chinese patents CN2212882Y, CN203313630U, CN101538622A, CN2671324Y have the following disadvantages: 1. seeds and growth substrates are mixed and filled in planting bags / blankets. Uneven distribution and uncontrollable density; ②The seeds and substrate are mixed and sandwiched in the middle of the vegetation blanket, and the growth is inhibited and easily deformed; ③The dense fiber layer has a small porosity, which is not conducive to sunlight and seedlings to pass through, so that the seedlings are trapped in the bag. growth, the bottom layer close to the slope is also a dense fiber layer, which hinders the function of grass roots from passing through and attaching to the stable slope; ④The non-stereoscopic structure between the upper and lower surfaces of the vegetation bag / blanket, if used on high and steep slopes, rainfall or Under the action of gravity, the growth substrate in the bag does not have enough adhesion and will sag and the plants will move

Even in the vegetation blanket of Chinese patent CN203313630U, there are well-shaped coconut fiber threads every 1m, but because the interval is too wide, and the coconut fiber bag is soft and has no support structure, the matrix will sag
