preparation example Construction

[0051] In some technical schemes, the preparation method of water retaining agent comprises:

[0052] Grinding the dried weathered coal to 300 mesh, adding sulfuric acid whose mass is 20%-60% of the pulverized weathered coal and whose concentration is 60-70% to react for 3-5 hours to obtain a flocculent reactant, and then add the flocculent reactant adding humus whose mass is 20-40% of the flocculent reactant, stirring and mixing to obtain the first mixed polymer;

[0053] Use ethyl acetate and / or xylene as a solvent, and add crushed plastic and / or foam to it, dissolve for 24-26 hours, then add starch with a mass of 20-25% of the crushed plastic and / or foam , shearing and emulsifying for 2-3 hours at a rotating speed of 3-35,000 r / min to obtain the second mixed polymer;

[0054] Mix the first mixed polymer and the second mixed polymer with a mass ratio of 1: (0.7-0.9) and then disperse and stir for 2-5 minutes under the condition of 2-25,000 r / min, and then in 1- Dispersing ...

Abstract

The invention provides a method for greening rock slopes in cold regions, which belongs to the field of ecological restoration. The method includes measuring the slope, vegetation coverage, rock Porosity and saturated water content; use slope, vegetation coverage, rock porosity and saturated water content as parameters to obtain the soil filling base of the rock slope to be greened; set anchor rods on the rock slope after leveling , and after fixing the geonet on the anchor rod, fill the vegetation matrix on the surface of the geonet according to the amount of foreign soil filling base; for the treated rock slope every 10-15 days, use 10-40kg / m 2 Irrigate with the same amount of water for 2-3 months. The invention adapts measures to local conditions, and the whole restoration process is more precise, and the germination rate and survival rate of grass seeds are improved by increasing the agglomeration characteristics, water retention and air permeability of the external matrix.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a method for greening rock slopes in cold regions. Background technique [0002] Slope is one of the important environments for human survival, and it is also an important part of engineering construction. In the process of engineering construction, human beings will inevitably transform the surface of the lithosphere. Among them, some large-scale engineering activities of human beings, such as: open-pit mining, road construction, hydropower construction, etc. , Often a large amount of excavation will be carried out on the rock mass, and some temporary or permanent rock engineering slopes will be formed. [0003] In recent years, with the continuous promotion and implementation of engineering construction, a large number of rock slopes have been formed in my country, especially in some alpine regions, the formation speed of rock slopes is gradually increasing; thus, the gre...
