Embodiment Construction

[0020] Clay: It is taken from the local area. It is a kind of yellow-colored and sticky soil unique to the local area. It is formed by the crustal rocks after long-term weathering and geological processes. The particle size ranges from >0.005 mm to <0.05 mm;

[0021] Peat soil: peat soil production base in Tonghua City, Jilin Province;

[0022] Water retaining agent: Beijing Green Singularity Technology Development Co., Ltd.;

[0023] Adhesive: Beijing Green Singularity Technology Development Co., Ltd.;

[0024] Organic fertilizer: Beijing Yite Organic Fertilizer Factory;

[0025] Grouting machine: Beijing Haoyuan Zhengye Machinery Equipment Co., Ltd. Model: SJ350.

[0026] In this embodiment, the lower slope section of Huangtutai Highway in the Mentougou section of National Highway 109 is selected, with a slope of about 70 degrees; the area is 1200m 2 The stone is limestone, and its particle size (diameter) has four grades from 5cm to 60cm; due to the different sizes of gr...

Abstract

The invention discloses soil for greening grouting on a soilless gravel slope and a grouting method thereof. The volume ratio of each component of the soil is: 100-1000 parts of substrate, 1 part of nutritional additive, and the addition amount of organic fertilizer is the substrate and nutrient 1% to 10% of the total volume of additives. The soil for greening grouting on soilless gravel slopes and the grouting method thereof according to the invention have a good effect on the ecological restoration of soilless gravel slopes. The invention provides sufficient growth environment and space for plants, the planting survival rate reaches over 95%, and the plants grow well, and the water retention effect is more than 2 times higher than that of "conventional soil-covered" planting plants, which not only saves materials, but also reduces maintenance The number of times, strong resistance to rain erosion. The invention realizes the self-propagation of artificial forced greening to natural vegetation, restores the ecology of the exposed soilless gravel surface well, and makes environmental protection and infrastructure harmonious.

Description

technical field [0001] The invention relates to a soil for greening, in particular to a soil for greening and grouting on soilless gravel slopes. Background technique [0002] At present, the country vigorously advocates the development of mountainous areas, economic development, and village-to-village projects. However, hydropower projects and other basic construction projects must split mountains and build roads, resulting in the formation of large-scale slopes in mountainous areas with a slope of about 35-85 degrees without soil debris. Stone slope. The gravels on this soilless gravel slope are of different sizes and have a deep accumulation depth. The deepest part can reach more than 2 meters without soil, and the slope is very unstable, prone to dangerous situations such as landslides. Due to the special ecological environment of the soilless gravel slope, the local microclimate has deteriorated and the biological chain has been destroyed. It is difficult to grow plant...
