Embodiment 1

[0025] 1. Slope reinforcement process

[0026] (1) First, use sand to make a slope with a top surface width of 20cm, a length of 40cm, a height of 20cm, and a slope ratio of 1:1 in the model box, such as figure 1 (make two identical slopes, one without any treatment, as a control group);

[0027] (2) Grind the dried soybeans into soybean powder, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration).

[0028] (3) Preparation of treatment powder: Mix urea and calcium chloride at a molar ratio of 1:1 (prepared immediately to prevent deterioration of the reagent).

[0029] (4) Insert 5 plastic pipes with a diameter of 2 cm from the top of the slope along the width and length direction at intervals, the distance between each plastic pipe is 10 cm, and take out the plastic pipe and the internal soil to make a grouting hole ,Such as figure 2 ;

[0030] (5) Preparation of plant urease reinforcement solution: Wei...

Embodiment 2

[0038] (1) First, use sand to make a slope with a top surface width of 20cm, a length of 40cm, a height of 20cm, and a slope ratio of 1:1 in the model box, such as figure 1 ;

[0039] (2) Grind the dried soybeans into soybean powder, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration).

[0040] (3) Preparation of treatment powder: Mix urea and calcium chloride at a molar ratio of 1:2 (prepared for current use to prevent deterioration of the reagent).

[0041] (4) Insert 5 plastic pipes with a diameter of 2 cm from the top of the slope along the width and length direction at intervals, the distance between each plastic pipe is 10 cm, and take out the plastic pipe and the internal soil to make a grouting hole ,Such as figure 2 ;

[0042] (5) Preparation of plant urease reinforcement solution: Weigh soybean flour and treated powder with a mass ratio of 1:2, and add a certain amount of water according to th...

Embodiment 3

[0046] (1) First, use sand and soil in the model box to make a slope with a top surface width of 20cm, a length of 40cm, a height of 20cm, and a slope ratio of 1:1, such as figure 1 ;

[0047] (2) Grind the dried soybeans into soybean powder, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration).

[0048] (3) Preparation of treatment powder: Mix urea and calcium chloride at a molar ratio of 2:1 (prepared for use now to prevent deterioration of the reagent).

[0049] (4) Insert 5 plastic pipes with a diameter of 2 cm from the top of the slope along the width and length direction at intervals, the distance between each plastic pipe is 10 cm, and take out the plastic pipe and the internal soil to make a grouting hole ,Such as figure 2 ;

[0050] (5) Preparation of plant urease reinforcement solution: Weigh soybean flour and treated powder of equal mass, and add a certain amount of water according to the mass...

Abstract

The invention discloses a slope strengthening method based on plant urease reinforcing liquid. Grouting treatment is carried out on the interior of a slope through the plant urease reinforcing liquid,and spraying treatment is carried out on the surface layer of the slope. The plant urease reinforcing liquid is prepared from bean flour rich in urease, processing powder and water, and constituentsof the processing powder include urea and calcium salt, wherein the mass ratio of the bean powder to the processing powder is 1:1-1:2, and the mass ratio of the bean powder to the water is 1:10-1:20.The plant urease reinforcing liquid obtained by adding the water into the bean powder and the processing powder is fed into the slope and sprayed onto the surface of the slope, crystallization of calcite is promoted through carbonate generated in a urea hydrolysis reaction and the rising of ph in the reaction process, low-carbon and environment-friendly crystal matter high in strength and adhesivestrength is formed and is filled and adhered among soil particles of the slope, the soil strength can be remarkably improved, the effect that the slope is strengthened is achieved, and the overall stability of the slope is improved.

Description

technical field [0001] The invention relates to a slope reinforcement method, in particular to a slope reinforcement method based on a plant urease reinforcement solution, and belongs to the technical field of civil engineering. Background technique [0002] With the development of civil engineering, more and more people pay attention to the stability of slopes, and the slope reinforcement technology is becoming more and more perfect. There are many slope protection technologies at this stage, such as soil nailing walls, riprap revetments, block Stone slope protection, block pavement slope protection, surface planting vegetation slope protection, etc., these technologies have disadvantages such as poor effect, high cost, complicated construction, and difficult maintenance. [0003] The plant urease reinforcement technology can effectively improve the strength of the slope soil and improve the stability of the slope through the biological process that is ubiquitous in nature....
