The scaffolding may have deformation because of the settlement of ground base. Then how to solve such settlement?
Set frame tubes or diagonal tubes on the transversal intersection of the double line scaffolding and stand a group of standing tubes every two lines until to the outside deformed scaffolding frame. All the frame tubes or diagonal tube shall set on solid and sturdy ground base.
Whenever there is any broken of the unload of scaffolding or in the connection system, recover the unload connection methods according to the original scheme design and recover the deformed parts and tubes. Such as for the correction of scaffolding towards outside, set a chain block of 5t in each open room to tie to the scaffolding body. Then loose all the rigid connection joints and the chain block will be tightened inverted at each joint until all the deformations have been corrected.
For the deformation of cantilevered beam exceeded its regulated value, then strengthen its anchor points and tighten its u jack heads to hijack the roof by the use of steel props.
