Abstract
The invention discloses the methods that the High water cut soil body is reinforced in vacuum pre-pressed joint biomineralization:A, the High water cut soil body is inputted into mud pit, then puts into bacillus subtilis powder and stirs evenly abundant flocculation;B, geotextiles are covered above mud pit and seal the soil body, will lay with the soil body, drain bar passes through geotextiles by evacuation duct system and connect with exhaust device, then carries out abundant pump drainage;C, it is connect by evacuation duct system with conveying device, silicate bacteria solution and carbon dioxide are transported in the soil body and are stood by evacuation duct and drain bar, exhaust device is connect with evacuation duct again and re-starts vacuum preloading draining, until the soil body sufficiently consolidates mineralising.The above method can combine biomineralization and vacuum preloading on the basis of bioflocculation, make the abundant consolidation and sclerosis of the soil body.
Description
Technical field
The present invention relates to a kind of methods of carbonate bacterium and phosphate bacterium composite deposition and consolidation pollution electroplating sludge.
Background technique
In the processing of traditional soil stabilization, vacuum preloading processing is generallyd use, but vacuum preloading processing is simply by subtracting
Moisture and air in few soil body, make soil body densification, but the property of the soil body fails to change, and the degree of consolidation is lower.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of vacuum pre-pressed joint biomineralizations to reinforce the High water cut soil body
Method, this method can pass through more environmentally-friendly mode more fully consolidated earth mass.
For this purpose, the method that the High water cut soil body is reinforced in vacuum pre-pressed joint biomineralization provided by the invention, including following step
Suddenly:
A, the High water cut soil body is inputted into mud pit, then puts into bacillus subtilis powder and stirs evenly abundant flocculation;
B, geotextiles are covered above mud pit and seal the soil body, will lay with the soil body, drain bar is worn by evacuation duct system
It crosses geotextiles to connect with exhaust device, then carries out abundant pump drainage;
C, connect with conveying device by evacuation duct system, by silicate bacteria solution and carbon dioxide pass through evacuation duct with
Drain bar is transported in the soil body and stands, then exhaust device is connect with evacuation duct and re-starts vacuum preloading draining, until
The soil body sufficiently consolidates mineralising.
Technical effect of the invention:It is flocculated, then carried out true to the soil body using bacillus subtilis powder in this method
Empty precompressed makes the preliminary consolidation and sclerosis of the soil body, then molten to each position input silicate bacteria of the soil body by evacuation duct and drain bar
Liquid and carbon dioxide make abundant carbon sequestration and mineralising in the soil body, further consolidate and promote hardness.
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 that the High water cut soil body is reinforced in vacuum pre-pressed joint biomineralization provided by the invention:
A, the High water cut soil body is inputted into mud pit, then puts into bacillus subtilis powder and stirs evenly abundant flocculation;
B, geotextiles are covered above mud pit and seal the soil body, will lay with the soil body, drain bar is worn by evacuation duct system
It crosses geotextiles to connect with exhaust device, then carries out abundant pump drainage;
C, connect with conveying device by evacuation duct system, by silicate bacteria solution and carbon dioxide pass through evacuation duct with
Drain bar is transported in the soil body and stands, then exhaust device is connect with evacuation duct and re-starts vacuum preloading draining, until
The soil body sufficiently consolidates mineralising.
It is 1% or 3% or 5% or 7% or 9% or 11% that bacillus subtilis powder, which accounts for the volume of soil body quality, in above-mentioned steps A.
The optimum mix amount that the bacillus subtilis powder accounts for soil body quality is %7.
It is 1% or 3% or 5% or 7% that silicate bacteria, which accounts for the volume of soil body quality, in above-mentioned steps C.The silicate bacteria
The optimum mix amount for accounting for soil body quality is 1%.
