Description
Technical field
It the utility model is related to mechanical equipment technical field, more particularly to it is a kind of using construction refuse regenerated building block
Process units.
Background technology
Building waste refers to the slag that people produce in the production activity for being engaged in the construction industries such as removal, construction, finishing, repairerment
Soil, waste and old concrete, the general designation of waste and old masonry and other discarded objects.Classify by generating source, building waste can be divided into engineering dregs,
Decoration garbage, removal rubbish, engineering slurry etc.;Classify by constituent, dregs, concrete block, broken can be divided into building waste
Stone, brick and tile fragment, waste mortar, mud, asphalt blocks, waste plastics, old metal, useless bamboo wood etc..
Building waste refers to the construction waste produced in engineering due to the reason such as artificial or natural, including waste residue soil,
Spoir, remaining mud and rejected material etc..These materials are itself no any help for building, but in the mistake of building
The material that is produced in journey can so reach preferable Engineering Project Construction, just because of being one, it is necessary to handled accordingly
A overall process, so the consideration of its link is prior.
With industrialization, the acceleration of urbanization process, construction industry is also fast-developing at the same time, the building waste produced together
Increasing, the quantity of Chinese architecture rubbish has accounted for more than the 1/3 of municipal refuse total amount.
By 2011, for Chinese city solid life refuse storage up to 7,000,000,000 tons, it was 21 that can calculate building waste total amount
Hundred million to 2,800,000,000 tons, the annual new building waste that produces is more than 300,000,000 tons.Simple stacking mode is such as taken to handle, annual newly-increased building
The processing of rubbish will all account for 1.5 hundred million to 200,000,000 square metres of lands used.China is in the economic construction high-speed developing period, every year can not
Produce several hundred million tons of building wastes with avoiding.If handling and utilizing not in time, society, environment and resource will be given to bring unfavorable shadow
Ring.
The quantity of China's building waste has accounted for the 30%-40% of municipal refuse total amount.With 500-600 tons/ten thousand square metres
Standard calculates that, to building waste the year two thousand twenty, China is also by about 30,000,000,000 square metres of newly-increased construction area, newly generated building waste
It will be a shocking numeral.However, most building wastes just transport countryside to without any processing by unit in charge of construction
Or rural area, air storage or landfill, the pork barrels such as substantial amounts of land acquisition expense, refuse collection expense are consumed, meanwhile, clear and heap
The problems such as being flown upward with dust, sand-lime of dropping during putting causes serious environmental pollution again.
1st, building waste, which is arbitrarily stacked, is also easy to produce security risk
The addressing that most cities building waste stacks ground largely has randomness, and it is hidden to leave many safety
Suffer from.Construction site is more nearby to stack place as the interim of building waste, due to only scheming easy for construction and lacking due protection
Measure, under the influence of extraneous factor, building waste heap, which occurs collapsing building waste, arbitrarily to be stacked -- and military original assistant officer is collapsed, and hinders road very
Happen occasionally to the phenomenon for rushing at other buildings.In suburb, swag irrigation canals and ditches are that the preferred of building waste stacks ground mostly, this is not only
The Regulation capacity to water body is reduced, also leads to top drainage and the reduction of flood carrying capacity.
2nd, building waste is serious to water resource pollution
Building waste due to the leaching of fermentation and rainwater, washes away during stacking and landfill, and surface water and underground
The immersion of water and sewage -- percolate or the leachate being percolated out, can cause the serious pollution of peripheral ground water and underground water.
Place where the garage is piled up mainly has the pollution channel of surface water body:Rubbish is scattered in the handling process to be stacked near field
Pool, in ditch;Place where the garage is piled up leachate is in overland flow, inflow surface water body;Leachate exists in place where the garage is piled up
It can be seeped into soil layer in surface water body nearby.Influence of the place where the garage is piled up to underground water is mainly then that refuse pollution is oozed with leachate
Enter water-bearing layer, secondly cause depth to pollute by being penetrated into supply water-bearing layer by the river and lake swag of refuse pollution.In landfill leachate not
Only contain a large amount of organic pollutions, but also contain a large amount of metals and non-metal contaminants, water-quality constituents is very complicated.Once drink
This contaminated water, it will very big harm is caused to human body.Building waste causes water pollution.
3rd, building waste influences air quality
With the continuous development in city, substantial amounts of building waste is arbitrarily stacked, not only land occupation, but also pollutes environment,
And directly or indirectly affect air quality.
The building waste in China is handled by the way of landfill mostly at present, but building waste is in stacking process,
Under the effect such as temperature, moisture, some organic substances are decomposed, and produce pernicious gas, as big in contained in building waste waste gypsum
Sulfate ion is measured, sulfate ion can be converted into the hydrogen sulfide with rotten-egg odour under anaerobic.
Waste paperboard and culled wood leachable lignin and tannic acid and decompose generation volatile organic acids under anaerobic,
This noxious gas emission will pollute air into air;Bacterium, dust in rubbish are drifted with the wind, cause the dirt to air
Dye;A small amount of flammable building waste can produce poisonous carcinogen again in burning process, cause the secondary pollution to air.Build
Building refuse causes air pollution.
4th, building waste land occupation reduces soil quality
With the increase of urban building waste amount, dumping point is also increasing, and the area of place where the garage is piled up also by
Flaring is big.The phenomenon that rubbish strives ground with people has arrived quite serious stage, and most suburban place where the garage is piled up is more with outdoor heap
Based on putting, after undergoing long-term expose to the sun and rain, harmful substance in rubbish (wherein include paint in urban building waste,
The polycyclic aromatic hydrocarbon structure compound matter that coating and pitch etc. discharge) penetrated into by landfill leachate in soil, so as to occur a series of
Physics, chemistry and biological respinse, such as filtering, absorption, precipitation, or absorb for root system of plant or absorbed by Microbe synthesis, cause
The pollution of Suburb Soil, so as to reduce soil quality.Building waste land occupation, reduces soil quality-Wu Yuancheng
In addition, the urban building waste of air storage, under the effect of a variety of external force, less crushed stone also can be near
Soil, change the material composition of soil, destroy the structure of soil, reduce the productivity of soil.In addition in urban building waste
The content of heavy metal is higher, and under the action of many factors, it will be chemically reacted so that heavy metal in soil content increases
Add, this will improve content of beary metal in crop.Contaminated soil, generally without natural self-purification capacity, it is also difficult to logical
Cross dilution diffusion method and mitigate its pollution level, it is necessary to take the method for costly transformation soil to solve.
Fold and bury
The main methods of China's building waste are by under its landfill at present.Its harm is:
It is to take a large amount of soils first.Only by taking Beijing as an example, shown according to related data:Built before Olympic venue construction to original
The dismounting built, and the construction in new building site, Beijing will set twenty or thirty building waste eliminate-incorporate-land, cause no small soil every year
Ground pressure.
Secondly cause serious environmental pollution.Adhesive for building, coating, paint in building waste are not only to be difficult to biology
The macromolecule polymer material of degraded, also containing harmful heavy metal element.These discarded objects are buried under the ground, and can cause underground
The pollution of water, directly jeopardizes the life of nearby residents.
It is to destroy soil texture, cause ground settlement again.Burying method now is:After 8 meters of garbage loading embeading plus bury 2 meters
Soil layer, but it is difficult to again long vegetation on soil layer substantially.And the earth's surface for filling region can then produce sedimentation and sink, to pass through suitable
The long time can be only achieved stable state
Construction refuse regenerated utilize in China has had certain technical foundation, the either research in laboratory or city
Field application has certain achievement.
Many discarded objects in building waste are sorted, reject or crush after, can be used as regenerated resources again sharp mostly
With such as:The metals such as steel scrap muscle, waste iron wire, waste electric wire and various steel scrap accessories, can for sand, for masonry mortar, plastering mortar,
Concrete cushion etc. is beaten, can be also used for making the building materials such as building block, Paving bricks, lattice brick.
Stacked due to building waste and compare concentration, place is than relatively limited, and traffic is not very convenient, it is proposed that select building
Refuse grinder.The equipment carries out multiple stage crushing to various large-scale bulk materials.Occupation area of equipment is small, can save a large amount of capital construction
And change of address expense;It is broken without material shipped off-site is crushed again that scene can be carried out to material, so as to substantially reduce thing
The freight of material.Construction waste crusher can also be very suitable for construction waste crushing according to actual field design development.
