Combine connecting structure.
Background technique
With the development of our country's economy, the construction infection of Urban Bridge increasingly by citizen, government, owner, set
Count the attention of unit and unit in charge of construction.Traditional construction method based on cast in situs is used in inner city, it will certainly be with
Existing road blocks traffic as construction site for a long time, and construction noise can not be controlled effectively, and construction equipment, auxiliary are set
It applies needs to repeat to configure, causes resources and energy consumption big, financial resource and material resource waste the problems such as more.How construction quality and warp guaranteed
Under the premise of Ji property, more quickly, efficiently, bridge is built up in low energy consumption, be the project that must be solved.
Since this century, the Oversea bridges such as domestic Donghai Bridge, the Yangtze Bridge, port Zhuhai and Macao bridge take the lead in using bridge
Beam prefabricated assembling technique, Shanghai City was in recent years in order to adapt to the requirement of green construction, good Min is overhead, northern transverse passage-way, S7 high
Frame, military project road be overhead, promotes the use of bridge prefabrication in the projects such as ring road under ring road, the overhead middle Xing Lu in north and south under middle ring National Road spells
Dress technology.Country vigorously advocates environmentally protective construction mode in recent years, and prefabricated assembled technology is to reduce construction pollution, promoted
The effective means of construction quality.
Urban Bridge substructure precast assembly technology mainly uses grout sleeve interconnection technique and ripple both at home and abroad at present
Two kinds of technology paths of pipe interconnection technique.Grout sleeve interconnection technique is a kind of live rebar connecting technology, is perfused in sleeve high
Strength mortar connects reinforcing bar by mortar bond stress.Bellows interconnection technique is a kind of live Bar Anchorage technology, in wave
High-strength mortar is perfused in line pipe, by bond stress Bar Anchorage in concrete component.Both technologies require constructing
In-site pouring high-strength mortar (is commonly called as wet construction), and the requirement for site operation is relatively high, any one sleeve or bellows
Grouting failure, can all lead to the reinforcing bar Joint failure, construction risk is larger.If can have one in the construction of precast pier on-site consolidation
Technique other than kind wet construction, reduces the technical difficulty to construction, it will pushes the universal of bridge prefabrication assembling technique.
