Abstract

The invention discloses a method for efficiently forming hollow bricks through high-pressure microorganism solid soil. The method comprises the following steps that 1, a material needed by a die is prepared; 2, organic glass plate with holes is assembled; 3, a light die is manufactured, and geotechnical cloth is tailored according to the size; 4, two transverse screw rods are disassembled; 5, a PVC pipeline is installed in a rectangular die cavity; 6, sandy soil is added to a cavity defined by the geotechnical cloth, and a geotechnical cloth top cover is sewn; 7, by means of the two transversescrew rods, the distance between two longitudinal side plates is fixed; 8, prepared bacteria are poured into a test piece, and then the whole die is placed in a chemical solution, and located under the pressure of two standard atmospheric pressures; and 9, after reacting is carried out for 3 days, biology solid soil hollow bricks are formed. Compared with traditional hollow bricks, the hollow bricks formed efficiently through the high-pressure microorganism solid soil does not need to be inserted and formed at a high temperature, air pollution is reduced, the environment is protected, and themethod is an ecological environment-friendly method.

Description

technical field

[0001] The invention relates to a method for manufacturing hollow bricks, in particular to a high-efficiency molding method for high-pressure microbial soil-fixing hollow bricks. Background technique

[0002] my country is in a period of rapid economic development, and the demand for construction land is constantly expanding, requiring more infrastructure construction to meet people's production and living needs. However, today's construction land resources are very limited, which requires land or The sand is solidified and improved. Traditional soil improvement methods often need to add a series of polluting chemical components, which may cause water pollution problems and even affect human health.

[0003] The scientific research team of the project team is researching new environment-friendly soil and sand reinforcement technology, using a microbial-induced calcium carbonate precipitation method that widely exists in nature in the biomineralization process...
