Problems solved by technology

[0003] Existing slope treatment technologies include sash, protective wall, shotcrete protection and chemical method protection, etc. These traditional engineering methods have the following problems: workload Large, high manpower and material resources consumption, long construction time
These measures belong to the rigid combination of slope surface and protection. In the early stage, the treatment objects need to be treated, resulting in increased time and cost. In the later stage, due to long-term exposure, it is not suitable for vegetation growth, and it is not conducive to environmental protection. Moisturizing ability, wind erosion resistance, and erosion resistance The ability is poor; the reinforcement of common chemical methods includes inorganic materials such as cement and organic materials such as polyacrylamide, which inevitably have certain toxicity and are not friendly to the environment
In the emerging method of using microorganisms to fix soil, microorganisms are difficult to cultivate, which is not conducive to large-scale promotion in actual engineering

Embodiment approach

[0026] A kind of slope reinforcement implementation method of canavalan urease in conjunction with biopolymer, it comprises the steps:

[0027] Step 1): Remove the gravel and garbage on the slope surface, dig out planting holes at equal intervals, sow the slope plant seeds into the planting holes, cover and level the soil again;

[0028] Step 2): pouring the clear liquid of canavaliase urease, the cementing mixed solution and the biopolymer solution at the planting hole, and repeatedly pouring the clear solution of the canavalin urease, the cemented mixed solution and the biopolymer solution at regular intervals;

[0029] Step 3): After the slope plant seeds germinate, pour the canavalin urease clear solution, the cementing mixed solution and the biopolymer solution into the planting hole again;

[0030] Step 4): The urea in the cementing mixed solution is decomposed by the urease in the clear solution of canavalan urease to generate carbonate ions, and combines with the calci...

Embodiment 1

[0040] Taking the 45°1# high and steep slope of a hydropower station slope greening site as an example, take a sample plot of 5m×5m as an example. Step 1 cleans up other rubbish such as broken stones, and step 2 digs out seed planting holes, and the adjacent interval is 20cm , sow tall fescue and bermudagrass seeds washed with deionized water at a density of 25g / m 2 and 8g / m 2 , Step 3: Infuse 45ml of clear bean urease liquid, 5ml of cementing mixture and 45ml of biopolymer solution every 4 days for 30 days. The cementing mixture and 45ml biopolymer solution were used to measure soil porosity, soil compressive strength, pH value, vegetation coverage, penetration strength, number of tall fescue and bermudagrass seeds per square meter before each pouring.

Embodiment 2

[0042] Take the nearby 45°2# high and steep slope, take 5m×5m as the sample plot, step 1 clean up the remaining rubbish such as gravel, step 2 dig out the seed planting holes, the adjacent interval is 20cm, and the seeds are washed with deionized water of tall fescue and bermudagrass seeds with a density of 25g / m 2 and 8g / m 2 , Step 3 Infuse 45ml of canavalin urease clear solution, 5ml of cementing mixture and 60ml of biopolymer solution every 4 days for 30 days. The cementing mixture and 60ml biopolymer solution were used to measure soil porosity, soil compressive strength, pH value, vegetation coverage, penetration strength, number of tall fescue and bermudagrass seeds per square meter before each pouring.

Abstract

The invention discloses a slope reinforcement implementation method of combining canavalia gladiata urease with a biopolymer. The slope reinforcement implementation method comprises the following steps that 1) broken stone blocks and garbage on the surface of a slope are removed, plant planting holes are dug at equal intervals, slope plant seeds are sown into the plant planting holes, and soil mass is covered and leveled again; 2) canavalia gladiata urease clear liquid, a cementing mixed solution and a biopolymer solution are poured into the plant planting holes, and the canavalia gladiata urease clear liquid, the cementing mixed solution and the biopolymer solution are poured repeatedly at set intervals; and 3) after the slope plant seeds sprout, the canavalia gladiata urease clear liquid, the cementing mixed solution and the biopolymer solution are poured into the plant planting holes again. According to the slope reinforcement implementation method, the anti-scouring capacity of the soil mass can be remarkably improved, the protection strength of vegetation to the slope is enhanced, the compressive strength of the slope is remarkably improved, the problem that a slope matrix is prone to being scoured by rainwater and eroded by wind and sand is solved, and application and popularization are better facilitated.
