Embodiment Construction
[0020] The present invention will be further described in detail in conjunction with the following examples, wherein the specific examples described are only used to explain the present invention, and are not intended to limit the invention.
[0021] The method for the carbonization and mineralization of photosynthetic microorganisms provided by the invention to strengthen residual soil comprises the following steps:
[0022] Step 1: first pour the calcium hydroxide solution into the residual soil;
[0023] Step 2: refilling with an equal volume of photosynthetic bacteria solution, said photosynthetic bacteria including cyanobacteria and / or purple bacteria;
[0024] Step 3: then inject carbon dioxide into the soil at low pressure for 6 hours;
[0025] Step 4: Repeat the above steps 1 to 3 until the calcium hydroxide solution and the photosynthetic bacteria solution cannot be injected.
[0026] The above-mentioned calcium hydroxide solution adopts the calcium hydroxide supern...

The invention discloses a method for reinforcing residual soil by carbonization and mineralization of photosynthetic microorganisms. The method includes the following steps that firstly, calcium hydroxide solutions are first injected into the residual soil; secondly, isovolumetric photosynthetic bacterium solutions are injected; thirdly, then carbon dioxide is introduced into soil mass at low pressure for six hours; and fourthly, the first step, the second step and the third step are cycled until the calcium hydroxide solutions and the photosynthetic bacterium solutions cannot be injected. Theinvention further discloses construction equipment used in the method for reinforcing the residual soil by carbonization and mineralization of the photosynthetic microorganisms. The method and the equipment can reinforce the residual soil more environmentally friendly and at low cost, and enable the reinforced soil mass to have certain self-repairing capability.
Description
Background technique [0001] Residual soil is the accumulation of loose debris and soil left in place after rock weathering without being transported. This weathered layer is called residual layer. The residual layer gradually transitions upward to the soil layer, and gradually transitions downward to the weakly weathered layer of semi-weathered rock. Soil layers, residual layers, and weathered rock layers form a complete weathering crust. [0002] Residual soil often appears in some mountains, and these residual soil areas are prone to landslides or falling rocks, posing a great safety hazard. [0003] The traditional treatment method generally uses concrete to be forcibly solidified, which causes great damage to the environment, is not environmentally friendly, and is incompatible with the surrounding natural environment. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for carbonizing and mineralizing r...
