Description
Technical field
The invention belongs to building engineering fields, and in particular to a kind of reinforced concrete inner support ecology Demolition Construction method.
Background technique
Traditional reinforced concrete inner support method for dismounting has pneumatic pick to cut method and two kinds of blasting procedure, cuts method sound for pneumatic pick
Sound reaches more than 100 decibels, and noise is big.Implement demolition blasting, to shift to an earlier date to each household resident around and be sent to notice to reassure the public, or even arrange
Temporarily withdraws and close a road to traffic, it is just implementable.The noise vibration and dust formed in demolishing process is huge on nearby residents influence, also
Have static mechanical patterning method: by reinforced concrete inner support be segmented into " disc saw " or " chain saw " cutting, the construction technology with
Construction noise is small, but generally requires to set up supporting row frame at reinforced concrete supporting beam bottom, as support bracket, project cost compared with
Height requires construction machinery stringent.
In conclusion traditional reinforced concrete inner support method for dismounting can usually generate biggish noise pollution, influence
Build surrounding enviroment；Though Novel static machine cuts method can effectively reduce construction noise, auxiliary stand need to be set up under beam, applied
Work cost is higher.It is worth noting that garbage collection processing difficulty is big after existing reinforced concrete inner support is removed, engineering is built
If the duration can generate certain influence.
In consideration of it, the actual needs based on current engineering, urgently inventing one kind at present not only can be effectively reduced environment dirt
Dye, and site operation efficiency can be improved, the reinforced concrete inner support ecology Demolition Construction of project cost can also be reduced
Method.
Summary of the invention
The purpose of the present invention is to provide a kind of reinforced concrete inner support ecology Demolition Construction method, not only difficulty of construction
It is low and high-efficient, the duration of a project is shortened, cost saves and environmental pollution is low, will not generate the pollution of noise, sewage etc., energy
