Abstract
The method of microorganism consolidation by grouting river bottom mud disclosed by the invention, includes the following steps：A, construction section both ends are subjected to river closure, and the river water in section of constructing is drained；B, drain bar is set into riverway sludge, draw water hair is inserted into bottom of river channel, drain bar and draw water hair are connect with total pipeline, total pipeline appearance configures exhaust device and conveying device, calcium source, bacillus subtilis and silicate bacteria mixed solution and carbon dioxide are conveyed into riverway sludge through total pipeline and drain bar by conveying device, riverway sludge surface puts into calcium source, bacillus subtilis and silicate bacteria mixed solution；C, after riverway sludge sufficiently flocculates and forms the layering of bed mud and top clear water, exhaust device is used to connect the moisture in pump drainage top clear water and mud with the draw water hair and the drain bar simultaneously first；D, drain bar is connect with conveying device again, by calcium source, silicate bacteria solution and carbon dioxide is defeated is transported in the soil body by drain bar, and stands to its solidification.The above method can large-area treatment riverway sludge, while the moisture pump drainage in the muck surface and the soil body after bioflocculation being walked, and convey mineralized bacterium into the soil body using original pump drainage channel, makes the soil body from obtaining abundant consolidation and sclerosis inside it to surface.
Description
Technical field
The present invention relates to a kind of methods of microorganism consolidation by grouting river bottom mud.
Background technique
In the processing of traditional riverway sludge commonly using the river sludge that directly scoops away, and in bottom of river channel casting concrete layer
Method, but this method is serious to the pollution of river, seriously destroys river channel natural ecology.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of method of microorganism consolidation by grouting river bottom mud, the party
Method can by it is more environmentally-friendly, more protect natural ecology in a manner of reinforce bottom of river channel.
For this purpose, the method for microorganism consolidation by grouting river bottom mud provided by the invention, includes the following steps：
A, construction section both ends are subjected to river closure, and the river water in section of constructing is drained；
B, drain bar is set into riverway sludge, is inserted into draw water hair to bottom of river channel, drain bar and draw water hair connect with total pipeline
Connect, total pipeline appearance configures exhaust device and conveying device, by conveying device through total pipeline and drain bar into riverway sludge
Calcium source, bacillus subtilis and silicate bacteria mixed solution and carbon dioxide are conveyed, riverway sludge surface puts into withered grass gemma
Bacillus and silicate bacteria mixed solution；
C, after riverway sludge sufficiently flocculates and forms the layering of bed mud and top clear water, first using exhaust device simultaneously with institute
It states draw water hair and connects moisture in pump drainage top clear water and mud with the drain bar；
D, drain bar is connect again with conveying device, calcium source, silicate bacteria solution and carbon dioxide is conveyed by drain bar
Into the soil body, and stand to its solidification.
Technical effect of the invention：The above method can large-area treatment riverway sludge, while by the silt after bioflocculation
Moisture pump drainage in mud surface and the soil body is walked, and mineralized bacterium is conveyed into the soil body using original pump drainage channel, make the soil body from its
Inside obtains abundant consolidation and sclerosis to surface.
Detailed description of the invention
Fig. 1 silicate bacteria mineralising calcium oxide generates calcite cementitious material XRD diagram.
Specific embodiment
With reference to embodiments, the present invention will be described in further detail, described in specific embodiment only use
To explain the present invention, it is not intended to limit the present invention.
The method of microorganism consolidation by grouting river bottom mud provided by the invention, includes the following steps：
A, construction section both ends are subjected to river closure, and the river water in section of constructing is drained；
B, drain bar is set into riverway sludge, is inserted into draw water hair to bottom of river channel, drain bar and draw water hair connect with total pipeline
Connect, total pipeline appearance configures exhaust device and conveying device, by conveying device through total pipeline and drain bar into riverway sludge
Calcium source, bacillus subtilis and silicate bacteria mixed solution and carbon dioxide are conveyed, riverway sludge surface puts into withered grass gemma
Bacillus and silicate bacteria mixed solution；
C, after riverway sludge sufficiently flocculates and forms the layering of bed mud and top clear water, first using exhaust device simultaneously with institute
It states draw water hair and connects moisture in pump drainage top clear water and mud with the drain bar；
D, drain bar is connect again with conveying device, calcium source, silicate bacteria solution and carbon dioxide is conveyed by drain bar
Into the soil body, calcium source generally selects calcium nitrate or calcium oxide, and stands to its solidification.
In the above method, after the step D, the drain bar and total pipeline are removed, in no rainy day gas every other day by silicon
Hydrochlorate bacterium mixed solution is sprayed at river surface using spraying device, continuous to spray more than three times, generally continuously to spray four
Suboptimum.
