Example Embodiment
[0025] Example 1
[0026] In this example, a construction method of microbial stirring grouting pile is used to strengthen the silt foundation, the design pile length is 9.0m, and the pile diameter is 0.6m. The steps of the method are as follows:
[0027] a. According to the ratio of adding 100g nano-calcium sulfate in every L of bacterial liquid, the bacterial liquid and nano-calcium sulfate are mixed to make a suspension;
[0028] b. Stir the suspension prepared in step a into the foundation to be reinforced to form a closely arranged cylindrical bacteria-containing soil mixing zone 1, and the amount of the suspension is 1% of the pore volume of the bacteria-containing soil mixing zone 1 0.9 times;
[0029] c. Insert the grouting pipe 3 into the center of the sterile zone 2 between the cylindrical bacteria-containing soil bodies;
[0030] d. Inject the mixed solution of calcium chloride and urea into the foundation through the grouting pipe 3, and let it stand for 6 hours ...

[0034] Example 2
[0035] In this example, a construction method of microbial stirring grouting pile is used to strengthen the silty clay foundation. The design pile length is 9.0m, and the pile diameter is 0.6m. The steps of the method are as follows:
[0036] a. According to the ratio of adding 165g nano-calcium sulfate in every L of bacterial liquid, the bacterial liquid is mixed with nano-calcium sulfate to make a suspension;
[0037] b. Stir the suspension prepared in step a into the foundation to be reinforced to form a closely arranged cylindrical bacteria-containing soil mixing zone 1, and the amount of the suspension is 1% of the pore volume of the bacteria-containing soil mixing zone 1 0.9 times;
[0038] c. Insert the grouting pipe 3 into the center of the sterile zone 2 between the cylindrical bacteria-containing soil bodies;
[0039] d. Inject the mixed solution of calcium chloride and urea into the foundation through the grouting pipe 3, and let it stand for 15...

[0043] Example 3
[0044] In this example, a construction method of microbial stirring grouting pile is used to strengthen the clay foundation, the design pile length is 9.0m, and the pile diameter is 0.6m. The steps of the method are as follows:
[0045] a. According to the ratio of adding 220g nano-calcium sulfate in every L of bacterial liquid, the bacterial liquid is mixed with nano-calcium sulfate to make a suspension;
[0046] b. Stir the suspension prepared in step a into the foundation to be reinforced to form a closely arranged cylindrical bacteria-containing soil mixing zone 1, and the amount of the suspension is 1% of the pore volume of the bacteria-containing soil mixing zone 1 0.9 times;
[0047] c. Insert the grouting pipe 3 into the center of the sterile zone 2 between the cylindrical bacteria-containing soil bodies;
[0048] d. Inject the mixed solution of calcium chloride and urea into the foundation through the grouting pipe 3, and let it stand for 24 hours...
