Description
Technical field
The present invention relates to CONSTRUCTION OF CABLE-STAYED BRIDGE technical fields, specifically, being related to a kind of hanging cable construction of king-tower vertical transfer cable-stayed bridge
System and its construction method.
Background technique
Cable-stayed bridge is also known as Cable stayed bridge, can be divided into steel deck cable stayed bridge, in conjunction with girder stayed-cable bridge and coagulation by material difference used in beam
Native girder stayed-cable bridge.Cable-stayed bridge is mainly made of Sarasota, girder, suspension cable, is directly to be pulled in girder on bridge tower with many drag-lines
A kind of bridge, be by the tower of pressure-bearing, the rope of tension and to hold a kind of structural system that curved beam body combines.Cable-stayed bridge is one
Kind of self-anchored type system, the horizontal force of suspension cable by joist support by.Beam is further supported at other than being supported on pier by king-post extraction
On suspension cable.More and more Cable stayed Bridge Main Towers use head tower structure, and since head tower self weight is lighter, vertical transfer construction is can be used in king-tower
And it shapes.
After Construction of Pylon, hanging cable of stay cable construction is carried out, traditional hanging cable method generally uses tower crane or truck crane
Lifting hanging cable is carried out, or sets up scaffold auxiliary messenger wire, or mounting suspension carries out lifting hanging cable at the top of king-tower.
According to tower crane lifting method carry out installation suspension cable, it is desirable that scene has tower crane mounting condition, to ground into
Row consolidation process, tower crane need to be attached on king-tower, and hanging cable, which finishes, to repair king-tower.
Installation suspension cable is carried out according to truck crane, when mounting height is higher, the truck crane tonnage needed is larger, lease
Expense is relatively high, and there are biggish insecurity factors for truck crane itself.
According to scaffold auxiliary messenger wire, scaffolding steel pipe lease expenses is high, and scaffold building risk is big, need to depend on master
Tower needs to repair king-tower after construction.
Hanging cable construction is carried out according to the mode in king-tower mounting suspension, needs to ask the item at the top of king-tower with mounting suspension
Part, and need additional suspender that hanger is lifted upper tower top and install.
Method more than carries out hanging cable construction, exist have ready conditions do not allow, security risk is high, the drawbacks such as costly.
Summary of the invention
