Description
Technical field
The present invention relates to bridge structure technical fields, specially a kind of prefabricated superposed type anti-collision wall for urban viaduct
And its construction method.
Background technology
At present, increasing with city vehicle, the unobstructed exception of urban transit system major trunk roads is important, and overpass is in city
Link role is often played in city's traffic, carries very big traffic pressure, neat and artistic degree is also an appearance of city
Important embodiment.
So in the newly-built or reconstruction and extension project of urban viaduct, construction period and construction quality are often policymaker
The emphasis of concern.And traditional overpass both sides anti-collision wall needs reinforcing bar binding, installation pipeline to bury generally using cast-in-place engineering method
The complicated procedures of forming such as template, casting concrete, maintenance, form removal inside and outside part, branch, low construction efficiency, the duration is longer, often results in
The lasting congestion of traffic restricts local socio-economic development；And anti-collision wall is up-narrow and down-wide, cast in situs quality is not easy to ensure,
The phenomenon that concrete surface voids and pits, often occurs, and seriously affects the aesthetic measure of anti-collision wall and the durability in later stage, needs
It often safeguards and overhauls, larger manpower financial capacity is caused to waste；In addition, during site operation, worker is needed in high aerial peace installation and dismantling
Template is unloaded, easily falls and causes safety accident, there are larger personal safety hidden danger.
Invention content
For above-mentioned technical problem, the purpose of the present invention is to provide a kind of for the prefabricated folded of urban viaduct
Box-like anti-collision wall and its construction method, rational in infrastructure, connection is reliable, and site operation speed can be greatly improved, and shortens construction work
