Abstract

The invention discloses a method for mineralizing and reinforcing a clay roadbed by using carbon fixation bacteria. The method comprises the following steps that A, streptomyces microflavus is cultured, and a bacteria solution is obtained; B, quartz sand is poured into clay for forming a roadbed, stirring for mixing is conducted, and then a mixture of the streptomyces microflavus bacteria solution, slaked lime and foam carbon dioxide is poured into the mixture of the clay and the quartz sand for sufficient stirring; C, standing is conducted to form a carbonized coagulum. The method for reinforcing the clay roadbed is more environmentally friendly, the operation is more convenient and faster, and the reinforcing effect is better.

Description

technical field

[0001] The invention relates to a method for mineralizing and strengthening clay roadbed by carbon-fixing bacteria. Background technique

[0002] The methods used to reinforce the traditional clay subgrade are as follows: 1. Dig away the clay, 2. Fill the subgrade with new materials such as slag and stones, and 3. Roll the road several times with a roller compactor to compact it. The above-mentioned reinforcement method consumes more man-hours, is costly, is inconvenient to operate, and is prone to collapse in the later stage. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a more convenient, quicker and more environmentally friendly method of using carbon-fixing bacteria to mineralize and reinforce clay roadbeds.

[0004] For this reason, the method provided by the invention adopts the mineralization of carbon-fixing bacteria to reinforce the clay roadbed, comprising the following steps: [000...
