Abstract
Post is constrained the present invention relates to a kind of high strength steel pipe using cementing microorganism cement, belongs to Structural Engineering field.High strength steel pipe constraint post includes high strength steel pipe, cementing microorganism cement.The high strength steel pipe is constrained in outside microorganism cement, so as to improve the compression strength of microorganism cement；The calcium carbonate crystal and cementing gravel solidfied material that the cementing microorganism cement is formed by microbial inoculum, cementing solution and sand by biochemical reaction are constituted.The invention provides a kind of cementing microorganism concrete column of high strength steel pipe constraint, can be used for using in high-rise, high-rise building combined structure system, concrete can be replaced as the vertical main material for carrying, there is compression strength higher under the sidewise restraint effect of high strength steel pipe.Microorganism cement realizes the zero-emission of pollutant in manufacturing process, meets the developing direction of green building, with more wide future in engineering applications.
Description
Technical field
The present invention relates to Structural Engineering field.
Background technology
Using the high strength steel pipe constraint post of cementing microorganism cement developed on the basis of steel tube confined concrete post
A kind of novel combined column structure type come.Steel tube confined concrete is the fill concrete in thin-wall steel tube, steel pipe not between
Undertake external loads, and a kind of main combined member that effect of contraction is played to core concrete, rigidity high with bearing capacity
Greatly, the characteristics of anti-seismic performance is superior, has been applied in high-rise, high-rise building and reinforcing engineering.Due to steel pipe not
It is stressed directly, can avoids or postpone thin-wall steel tube and local buckling is produced because of compression, therefore steel tension can be given full play to
The characteristics of mechanical property is good.It has been applied to the solidification of loosening sand or silt using microbial inoculum and cementing solution
In composite pile foundation and reinforced soft soil ground.Microbial inoculum and cementing solution are substituted steel by the present invention with the mixing cured thing of sand
The effect of the concrete in pipe confined concrete models, forms a kind of new high strength steel pipe using cementing microorganism cement and constrains
Post.In existing document, there is not yet this constrains the structure type of post using the high strength steel pipe of cementing microorganism cement.
The invention provides a kind of cementing microorganism concrete column of high strength steel pipe constraint, can be used for using high-rise, Super High
In building composite structure system, concrete can be replaced as the vertical main material for carrying, in the sidewise restraint of high strength steel pipe
Effect is lower to have compression strength higher.Because microorganism cement can substitute concrete, thus reduce conventional cement firing
During carbon dioxide and other pollutants discharge, be a kind of green material.Microorganism cement is in manufacturing process
The zero-emission of pollutant is realized, meets the developing direction of green building, with more wide future in engineering applications.The invention
Processing and fabricating it is convenient, can be mixed and stirred by the way of normal concrete, poured and be conserved, because high strength steel pipe can generation
For formwork, thus convenient and quick construction.
The content of the invention
The invention provides a kind of cementing microorganism concrete column of novel high-strength steel tube confinement, substituted using microorganism cement
Conventional concrete, forms steel tube confinement post, in can be used for using high-rise, high-rise building combined structure system, can replace mixed
Solidifying soil has compression strength higher as the vertical main material for carrying under the sidewise restraint effect of high strength steel pipe.Micro- life
Thing cement realizes the zero-emission of pollutant in manufacturing process, meets the developing direction of green building.
Technical scheme is as follows：
A kind of cementing microorganism concrete column of novel high-strength steel tube confinement, it is characterised in that：Its high strength steel pipe constrains post bag
Include high strength steel pipe, cementing microorganism cement.Cementing microorganism cement passes through bioid by microbial inoculum, cementing solution and sand
Learn calcium carbonate crystal and cementing gravel solidfied material composition that reaction is formed；High strength steel pipe constrains in the outer of cementing microorganism cement
Portion, improves the resistance to compression bearing capacity of cementing microorganism cement such that it is able to instead of concrete as the vertical main member for carrying.
The present invention has following effective effect：
1. replace the effect of conventional cement using novel microbial cement, reduce carbon emission, be a kind of environmental protection material
Material.
2. microorganism cement has compression strength higher under high strength steel pipe effect of contraction, can undertake building structure
Vertical load.
3. processing and fabricating is convenient, can be mixed and stirred by the way of normal concrete, poured and be conserved, due to high-strength steel
Pipe can replace formwork, thus convenient and quick construction.
This can reduce the discharge of pollutant using the high strength steel pipe constraint post of cementing microorganism cement, bearing capacity compared with
Height, easy construction, with more wide future in engineering applications.
Brief description of the drawings

Fig. 2 is strong constraint post top view high of the invention.
In figure：1-high strength steel pipe, 2-cementing microorganism cement.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A. microbial inoculum 3, cementing solution 4, sand 5 are transported to job site and are mixed and stirred, form microorganism cement
2。
B. after high strength steel pipe 1 is lifted in place, microorganism cement 2 is poured to high strength steel pipe and is conserved.
The present invention provides a kind of high strength steel pipe constraint post using cementing microorganism cement, is substituted using microorganism cement and passed
System concrete, forms steel tube confinement post, in can be used for using high-rise, high-rise building combined structure system, can replace coagulation
Soil has compression strength higher as the vertical main material for carrying under the sidewise restraint effect of high strength steel pipe.Microorganism
Cement realizes the zero-emission of pollutant in manufacturing process, meets the developing direction of green building, has a extensive future.
