Description
Technical field
The invention belongs to building engineering field, and in particular to a kind of reinforced concrete inner support ecology Demolition Construction method.
Background technology
Traditional reinforced concrete inner support method for dismounting has pneumatic pick to cut two kinds of method and blasting procedure, is that pneumatic pick cuts method sound
Sound reaches more than 100 decibels, and noise is big.Implement demolition blasting, to shift to an earlier date and be sent to notice to reassure the public to each household resident around, or even arrange
Temporarily withdraw and close a road to traffic, can just implement.The noise vibration and dust formed in demolishing process influence huge to nearby residents, also
There is static mechanical patterning method：By reinforced concrete inner support be segmented into " disc saw " or " chain saw " cut-out, the construction technology with
Construction noise is small, but generally requires to set up supporting row frame at reinforced concrete support beam bottom, as support bracket, construction costs compared with
Height, it is strict to construction machinery requirement.
In sum, traditional reinforced concrete inner support method for dismounting can usually produce larger noise pollution, influence
Building 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 worthy of note that, garbage collection intractability is big after existing reinforced concrete inner support is removed, and engineering is built
If the duration can produce certain influence.
In consideration of it, being actually needed based on current engineering, urgently invent that a kind of not only can effectively to reduce environment dirty at present
Dye, and site operation efficiency can be improved, the reinforced concrete inner support ecology Demolition Construction of construction costs can also be reduced
Method.
The content of the invention
