Problems solved by technology

At the same time, for some slopes with poor soil, it is not conducive to the growth of plants. Although the ordinary soil layer has certain fertility and soil activity, the thickness of the soil layer is relatively thin, and the ability to supply nutrients and fertilizers is relatively limited. Solve the problem of short-term supply of nutrients, which is not conducive to the long-term growth and development of vegetation
Secondly, the ordinary soil layer does not have good bonding force with the slope to be repaired, and cannot play the role of reinforcement. Once encountering slightly bad weather conditions, it may pose a threat to the stability of the slope, and even small landslide phenomenon

Embodiment 1

[0043] This embodiment provides an ecological slope protection method based on straw reinforced soil substrate, such as Figure 1~2As shown, its constituent elements mainly include: straw-reinforced soil substrate 1, plant seeds, slope holes 2, geogrid 3, and slope 4 to be repaired; the present invention provides a straw-reinforced soil substrate 1. The straw-reinforced soil substrate 1 includes main materials and auxiliary materials. The main materials include straw and common loess, wherein the straw is rice straw, and the rice straw needs to be soaked in polyvinyl alcohol powder and water at a ratio of 1: 40% by weight in the glue solution for 1 day to enhance its anti-corrosion ability; the common loess refers to the accumulated soil under the loess slope and the loess at the foot of the slope; the auxiliary materials include Trichoderma, potassium salt, trace Elemental fertilizer, lime, polyvinyl alcohol powder; the rice straw reinforcement ratio of loess in the main mate...

Embodiment 2

[0054] The difference between the present embodiment and the foregoing embodiment is that corn stalks are used as the reinforcement material for the soil, which specifically includes the following steps:

[0055] The straw-reinforced soil substrate 1 includes main materials and auxiliary materials. The main materials include straw and common loess, wherein the straw is corn straw, and after the corn straw is crushed into 1-10 cm, it is soaked in polyvinyl alcohol powder and Water was placed in the glue solution formed with a mass ratio of 1:40 for 1 day to enhance its corrosion resistance; the following implementation content was the same as in Example 1.

[0056] The ecological slope protection method based on the straw reinforced soil substrate provided in this embodiment comprises the following steps:

[0057] Step 1: Repair and level the slope surface that needs to be repaired, remove the sharp protrusions, and prevent the geogrid from being damaged by sharp or hard object...

Embodiment 3

[0063] The difference between the present embodiment and the foregoing embodiment is that its application site is a high and steep slope that needs to be repaired, and it specifically includes the following steps:

[0064] The straw-reinforced soil substrate 1 is the same as that in Example 1. The mass percentages of main ingredients, Trichoderma, potassium salt, trace element fertilizer and lime in the straw-reinforced soil substrate 1 are 96.8:0.1:0.1:0.5:2.5.

[0065] The ecological slope protection method based on the straw reinforced soil substrate provided in this embodiment comprises the following steps:

[0066] Step 1: Repair and level the slope that needs to be repaired, first use the 3D net to protect the slope to strengthen the overall structure of the slope, and at the same time prevent the loss of soil nutrients, and leave holes corresponding to the plane area of ​​the slope holes on the 3D net ;

[0067] Step 2: According to the measured length, width, and hei...

Abstract

The invention discloses an ecological slope protection method based on straw reinforced soil substrate. Including straw-reinforced soil substrate, plant seeds and civil grids, straw-reinforced soil substrate includes main materials and auxiliary materials, the main materials include straw and ordinary loess, the two are mixed with water to form straw-reinforced soil, and auxiliary materials include Trichoderma , potassium salt, trace element fertilizer, lime, polyvinyl alcohol powder, wherein the straw is soaked in polyvinyl alcohol solution for a period of time. Slope protection method: first level the slope surface, excavate holes in the soil layer on the slope surface, insert a part of the cage-shaped geogrid into the hole, and fill it with straw-reinforced soil substrate, cover the slope surface and the surface of the civil grid A mixture of straw-reinforced soil substrate and pure plant seeds completes the construction of the slope protection substrate. The invention can effectively recycle waste straw, reduce environmental pollution, and simultaneously improve the current situation of poor stability of the base material of ecological slope protection and barren soil of the base material. The method has low cost and wide application prospect.

Description

technical field [0001] The invention relates to an ecological slope protection method, in particular to an ecological slope protection method based on a straw-reinforced soil substrate, and belongs to the fields of slope protection, water and soil conservation and ecological restoration. Background technique [0002] As a major grain-producing country in the world, our country produces a lot of straw every year, which becomes agricultural waste in many places and puts a huge pressure on the environment. Some straws are not effectively used and are burned because they have no place to pile up, directly polluting the environment . Therefore, rational utilization of straw resources and sustainable utilization of agricultural waste has become an increasingly urgent issue. At the same time, for some slopes with poor soil, it is not conducive to the growth of plants. Although the ordinary soil layer has certain fertility and soil activity, the thickness of the soil layer is relat...
