Abstract
The present invention relates to a process for the treatment of building rubbish and a method of regeneration use. The method uses building rubbish which use waste bricks and waste concrete as principal ingredients. After the waste bricks and the waste concrete are manually sorted, the waste bricks and the waste concrete are respectively crushed into the particle size of smaller than 200mm. impurities such as metal products, blocks, etc. are removed, and the waste bricks and the waste concrete are respectively crushed into the graininess of smaller than 60mm by a machine to form available regeneration stone materials. Regeneration stones made by the waste bricks are respectively mixed with sand, fly ash and lime to form the filler of building foundation or road base materials. Regeneration stones made by waste concrete blocks are mixed with cement and the sand to form new concrete material. The present invention provides an approach of regeneration use for building rubbish and solves the problems that farmland is occupied by the building rubbish and environment is polluted.
Description
The present invention relates to the processing and the regeneration of building waste.
Along with the development of urban construction, reconstruction of the old city town and the building waste that produces is increasing.And the method for handling a large amount of building wastes at present is to bury hole or air storage, not only occupies cultivated land, contaminated environment, and has caused the wasting of resources.
The objective of the invention is to be that be the characteristics of main component at the problems referred to above and urban architecture rubbish with useless brick and waste concrete piece, a kind of processing and regeneration method of building waste are provided, occupy cultivated land and problem of environment pollution caused to solve it, and realize the purpose of regenerated resource development and utilization, saving resource.
The technical scheme of being taked is for achieving the above object: a kind of processing of building waste and the method for regeneration, it utilizes with useless brick and waste concrete piece is the building waste of main component, (a) with waste concrete piece and useless fragment of brick sorting, be crushed to granularity respectively less than 200mm, metal object, wooden unit impurity are rejected; (b) granularity that will reject impurity is crushed to granularity respectively less than 60mm again less than concrete block and the queen closer of 200mm, forms available regeneration stone material.
Technical scheme of the present invention also comprises: will be mixed with sand and flyash, lime to form respectively by the regeneration stone material that useless fragment of brick is made and change underfill material and roadbed material; To mix with cement, sand by the regeneration stone material that the waste concrete piece is made and form new concrete material.
In technical scheme of the present invention, the regeneration stone of being made by useless fragment of brick when composition changes underfill material and the weight ratio of sand are 3: 1; The weight ratio of regeneration stone of being made by useless fragment of brick when forming roadbed material and flyash, lime is 4: 5: 1; The weight ratio of regeneration stone of being made by the waste concrete piece when forming concrete material and sand, cement is 4: 2: 1.
The present invention is with the main building waste of city reconstruction of the old city town---and useless fragment of brick and concrete block carry out processing regenerated utilization, saved because of landfill and required human and material resources, the financial resources of stacking processing, solved because of its processing and taken a large amount of arable lands and environmental pollution problems, for turning waste into wealth, regenerated utilization of building waste provides a valid approach, but the construction material resource of saves valuable.
Below in conjunction with embodiment technical scheme of the present invention is described further.
To be that the building waste of main component is transported to special-purpose tipple with useless brick and waste concrete piece, after at first carrying out sorting via manually will give up fragment of brick and waste concrete piece, be crushed to granularity respectively less than below the 200mm, impurity such as metal object, timber are rejected, and then send in the jaw crusher through conveying machinery and vibrating feed machinery respectively, be crushed to below the granularity 60mm, form available regeneration stone material.
Embodiment 1: will mix sand by the regeneration stone that useless fragment of brick is made, its weight ratio with sand is 3: 1, can form after the mixing to build and change underfill material.The foundation ditch of dark 2-5m is by after the mix layered backfill of said ratio and rolling, and the foundation bearing capacity standard value can reach 300KPa, can do 7-10 one storey building ground.
Embodiment 2: will mix flyash and lime by the regeneration stone that useless fragment of brick is made, its weight ratio with flyash, lime is 4: 5: 1, fully can form roadbed material after the mixing.This material is the slow setting silicate material, and the roadbase of making will be formed integral layer, and its intensity is with increasing the length of time under certain temperature, humidity.Has plate body, water stability and certain freezing stability preferably after knot is hard.The unconfined compressive strength of soaking the saturated 28 day length of time in its construction back is 2MPa, and increases with prolonging the length of time; The modulus of resilience reaches 750MPa in the time of 1 month, reached 800MPa in 3 months, reaches 1000MPa in 6 months; Its freezing stability: five times the drying and watering cycle loss in weight is bordering on zero; Its temperature contracts coefficient less than 0.0005, and the coefficient of shrinkage is 0.0005～0.0002.Be applicable to the underlayment of main trunk road and the basic unit of less important arterial highway.
Embodiment 3: the regeneration stone that will make by the waste concrete piece and sand, cement by weight 4: 2: 1 and with the water mix, can form new concrete, its label can reach C10, is widely used in the concrete cushion of building foundation.
