Embodiment 1
[0046] This embodiment provides a microbial restoration fluid applied to slope protection of sandy foundation pits. The microbial remediation solution includes a microbial mineralization solution and a microbial cementation solution that are independent of each other.
[0047] Wherein, the microbial mineralization solution is composed of mineralizing bacteria liquid and mineralizing bacteria nutrient solution which are independent of each other. The mineralization bacteria liquid includes 1# mineralization bacteria liquid and 2# mineralization bacteria liquid used independently; the spraying amount of the mineralization bacteria liquid is (5~10) L / m 2 , the spraying volume ratio of the mineralizing bacteria liquid and the mineralizing bacteria nutrient solution is 1:(2~5). The mineralizing bacteria nutrient solution includes 3g / L~6g / L NutrientBroth, 0.4mol / L~0.7mol / L CO(NH 2 ) 2 , 0.25mol / L~0.5mol / L CaCl 2 2H 2 O, 0.2mol / L~0.3mol / L NH 4 Cl, 0.15mol / L~0.2mol / L NaHCO 3 . ...
Embodiment 2
[0055] This example provides an application method of microbial restoration fluid in the slope protection of sandy foundation pits, which is applied to sandy foundations with a slope range of (1:0.75) to (1:1.5) in the sandy foundation pit pit.
[0056] refer to image 3 , when the sandy foundation pit is not excavated in layers, the application method includes the following steps:
[0057] Step 1 provides the microbiological remediation fluid applied to the slope protection of sandy foundation pits prepared according to Example 1. Wherein, adopt sprayer to spray described microbial restoration liquid to the side slope surface of described sandy foundation pit. The spray rate of the microbial remediation liquid should ensure that the microbial remediation liquid penetrates into the spray point and does not flow down along the side slope surface of the sandy foundation pit. And before spraying the microbial restoration solution on the sandy foundation pit, first determine th...
Embodiment 3
[0068] In implementation 1, the bacillus cementum bacterial strain that is used to prepare desert self-source cementing bacteria liquid is isolated from desert red loam. Its specific separation method is as follows:
[0069] refer to Figure 9 , the isolation method of bacillus cementum comprises the following steps:
[0070] S1. Take n grams of desert soil at 120-150 cm from the desert soil in Inner Mongolia, put it into 10 n grams of sterile distilled water and shake it for 15-20 minutes, then let it stand for 12 hours, and take the supernatant for subsequent use;
[0071] S2. Inoculate the supernatant into No. 1 liquid medium, and carry out constant temperature shaking culture;
[0072] S3. According to the concentration gradient of dilution, prepare the liquid after constant temperature shaking culture in step S2 into dilution solutions of different concentrations, and apply the dilution solutions of different concentrations on the plates with No. 1 solid medium on the u...
