Description
Technical field
The present invention relates to ancient building recovery technology field, in particular to a kind of side that city-wall brick is prepared using shield waste pulp
Method.
Background technique
With the continuous promotion of Chinese national economy, more and more tier 2 cities, even three line cities are high, also start to repair
Subway is built, thus generates a large amount of shield waste pulp every year.During shield-tunneling construction, excavation earth material is mixed to form highly dense with muddy water
Mud is spent, by slurry pump and pipeline to ground, by drum screen, the physical separation such as desander are formed can not reuse in engineering
Thick slurry, thickness slurry is discharged into abandoning stock tank.The slurry-outlet quantity of slurry shield is generally 2~3 times of digging volume, if without appropriate, it will
Periphery ecological environment can be damaged.Meanwhile shield spoir is underground deep layer soil property, the pollution of itself is small, is fabulous
Recycling material, therefore proper treatment should be subject to, in favor of development and utilization from now on.
Traditional mud conditioning technology has landfill method, solidification method, soil cultivating method etc..Common landfill method volume of earthwork
It is bigger, and do not have ecological functions, hidden danger may be left for Environmental security；Solidification method high expensive, and thoroughly change
The physical property for having become shield spoir increases the difficulty of resource utilization；Soil cultivating method is to topography and geomorphology and soil knot
Structure is more demanding, is not easy expansion and implements.
Currently, the construction of the characteristic small town town He Gu old countries is being carried out in domestic many places, need a large amount of caesious imitative
Ancient city wall brick, country again forbid fire clay brick, this for the resource utilization of shield waste pulp provide good Policy Background with
Huge social demand.
Summary of the invention
The present invention provides a kind of methods for preparing city-wall brick using shield waste pulp, and preparation method is simple for this, cost
It is low, energy conservation and environmental protection, use easy to spread.
The technical solution of the present invention is as follows:
A method of city-wall brick is prepared using shield waste pulp, comprising the following steps:
(1) it stirs: by percentage to the quality, by raw material by following proportion mixing: shield waste pulp 55%~65%, flyash
15%~25%, miberal powder 15%~20%, exciting agent 3%~5%, iron oxide black 0~2%；
(2) it forms: hydraulic brick making machine molding, briquetting pressure 20 will be sent by the raw material of step (1) after mixing evenly
~40MPa opened sample after 24 hours；
(6) it conserves: molding city-wall brick sprinkling maintenance 7 days.
Wherein it is preferred to which the moisture content of the shield waste pulp, less than 25%, density is less than 1.3g/cm3。
Wherein it is preferred to which the miberal powder is solid waste-Water Quenching Slag of iron-smelter sale, drying grinding to 300 mesh
The above fineness.
Wherein it is preferred to which it is 0.5~1.5:1 bunt gypsum and white cement that the exciting agent, which is weight ratio,.
Wherein it is preferred to which the fineness of the bunt gypsum is 200 mesh, the fineness of the white cement is 200 mesh.
The exciting agent is saline and alkaline composite material, and bunt gypsum and white cement clinker can provide villaumite excitation, sulphate activation
It with good triple stimulation effects caused by alkali-activated carbonatite, can react, aggregate into strong with shield waste pulp, flyash and miberal powder
Higher bulk material is spent, the intensity requirement of city-wall brick is met.Also, added with iron oxide black, the mesh for adjusting city-wall brick color is played
's.If flyash color is darker, iron oxide black can be used less, can also not have to, keep the color of city-wall brick more life-like.
Beneficial effects of the present invention:
1. shield waste pulp have been carried out resource utilization by preparation method of the invention, scientific disposal makes its minimizing, harmless
Change, recycling and innoxious, it is at low cost, and energy-saving ring is kept.
2. there is good compression strength and frost resistance using the city-wall brick of the method for the present invention preparation, and brick body color is blueness
Grey, color are more life-like.
3. city-wall brick of the invention uses compression moulding, complex production process in sintering process, energy consumption height, Yi Chan great are avoided
The problem of carbon dioxide isothermal chamber gas of amount.
4. of the invention, preparation method is simple, at low cost, and energy conservation and environmental protection.
