The movable scaffolding system is a kind of built-in mould, use pier or support platform as the support for the cast-in-situ construction of the bridge.
It is widely used in the continuous beam construction of road bridge and railway bridge, which is the more advanced construction method.
The movable scaffolding system can be divided to overhead movable scaffolding system and underslung movable scaffolding system.
Overhead movable scaffolding system
It is composed by leg mechanism, support girder, inner and side mould, main beam lifting mechanism, side suspension and hydraulic system etc.
Underslung movable scaffolding system
It is composed by pier side bracket, supporting platform, main beam, bottom mould and cross linking, side mould and support, medium pole beam, typhoon protection device and hydraulic system etc.
◆1.The construction is not affected by the conditions such as the river, the clearance of the road bridge and the foundation.
◆2.The construction process is programmed, the degree of mechanization is high, the quality is good.
◆3.The upper and lower structures can be constructed in parallel and can shorten the construction period.
◆4.Bridge equipment construction, reusable.
◆5.Stress clear, safety, construction deformation and quality are relatively easy to control.
