Isoenergetic deformation composite foundation for solidifying aggregate through microorganisms, and construction method

Abstract

The invention discloses an isoenergetic deformation composite foundation for solidifying aggregate through microorganisms, and a construction method. The composite foundation comprises a plurality ofpile bodies and cushion layers, the cushion layers are arranged at the top ends of the pile bodies, the pile bodies are connected into an integral structure through the cushion layers, and the pile bodies and the cushion layers are filled with the aggregate solidified through the microorganisms. The method comprises the following steps: 1, a field is leveled; 2, construction is prepared; 3, a piledriver is in place; 4, hammering is conducted to form a hole; 5, the hole is filled with the aggregate; 6, the work of the step 5 is repeated; 7, an isoenergetic deformation compaction pile of the aggregate solidified through the microorganisms is formed; 8, the pile driver is moved to the next pile; 9, the ground is tamped; and 10, the cushion layers are flush with the ground surface. The isoenergetic deformation composite foundation for solidifying the aggregate through the microorganisms, and the construction method have the advantages that local materials are used, waste is turned into wealth, environmental protection is facilitated, the engineering cost is saved, and the concept of green development is met.

Description

technical field [0001] The invention relates to a composite foundation and a construction method, in particular to an equal-energy deformation composite foundation and a construction method using microorganisms to solidify aggregate. Background technique [0002] At present, large-scale engineering construction is being carried out on vast islands and reefs far away from the mainland. However, the islands and reefs are far away from the mainland, lack of sand, gravel and fresh water resources, and the transportation is inconvenient. If the sand, gravel and fresh water are transported by sea from the distant mainland, the cost of sea transport of sand, gravel and fresh water per cubic meter will reach 0.16-0.19 based on the shipping cost of bulk cargo. Considering the freight of cement and mineral admixtures, the cost of raw materials per cubic meter of concrete is as high as 2,600 to 2,800 yuan, which greatly increases the cost of the project, and it is difficult to guarante...
