Description
Technical field
The present invention relates to a kind of processing method for processing the mud dregs produced in Process of Urban Development, especially exist
The soil dug out in urban construction, such as subway work, building construction dig the processing method of the dregs of ground generation.
Technical background
Subway construction and high-rise building building are the marks that a city develops rapidly.Built in subway construction and high-rise building
In building, the substantial amounts of soil for being mined out will necessarily be produced.The method for processing this kind of soil now only has a kind of mode, is exactly
In the perimeter strip in city, some soil are set up by Na Chang in the place for being adapted to mound.The soil produced in Process of Urban Development
Directly these be sent to by soil car filled by Na Chang, this processing method its be substantially exactly the local excavation for needing to build
Soil out has been transported to the place that need not temporarily carry out urban construction.But, conduct is adapted in surrounding city
Received place side, it is also fewer and feweri, have no alternative but, an overload operation can only be received by existing, form artificial massif, this people
For massif soil property it is of a relatively loose, once by geographical environment change and weather conditions influenceed, such as earthquake or for a long time rain,
It is easy to cause artificial landslide, causes immeasurable artificial loss.Such as this summer, City in South China it is this by Na Chang
Artificial landslide, just almost several industrial areas on massif periphery are all ruined and are buried, cause huge casualties and wealth
Produce loss.
Chinese patent literature CN1868597A discloses a kind of integrated conduct method of building waste, its process step bag
Include:After building waste is suitably crushed, the debris such as metal therein, bamboo and wood, plastics are sorted and is detected, then by surplus material
Pour into the service sink of the lattice screen frame (unit) with three stage layereds, cleaned with water and stirred, material through three stage layereds lattice screen frame (unit)
After screening, be separated into from the bottom to top cement mortar, in, little particle sandstone grain and large-block material layering discharge, cement mortar also passes through
Multi-stage mechanical separating sieve production line, continues screening and is separated into mud and husky, Shi Li;The large-block material separated is delivered to brokenly again
Broken crusher machine, crush after material again through three-level screen frame (unit) sizing screening, be separated into powder and it is small, in, bulky grain sandstone grain;And
The mud separated is precipitated in being then conveyed into sedimentation basin, is dried to tonerde, and water then enters circulatory pool and recycles.It is this
Although method meets the advantage of the theory of environmental protection and sustainable development with the recyclable comprehensive utilization of all materials after treatment,
But, in actual implementation process, due to its first have to by building waste suitably crush after, then again by metal therein, bamboo,
The debris such as wood, plastics sorting detection, this process processing speed is very slow, because subway or skyscraper are all in the very short time
Substantial amounts of soil occurs, if all first crushed, then the debris such as metal, bamboo and wood, plastics is sorted, this is accomplished by substantial amounts of stockyard
To store pending silt particle during yesterday, it is for this is to the urban land of an inch of land is an inch of gold or unsuitable.
Therefore, how soil of the quick industrial treatment as produced by urban construction, make its turn waste into wealth be pendulum in people
In face of a problem demanding prompt solution.
The content of the invention
In order to solve the deficiencies in the prior art, the present invention is provided to society and a kind of will can produced in Process of Urban Development
Soil, carries out rapid industrial treatment, so that it becomes the method for the industrial treatment mud dregs of construction material and industrial soil.
