Description
Technical field
The present invention relates to a kind of seamless pavement structure that is connected with floorings of optimization CRCP and construction method.
Background technology
At present, with growing, the continuous reinforcement concrete topping of engineering technology（CRCP）Use also more and more popularize, though
Right continuous reinforcement concrete topping is because of the effect of contraction of its continuous reinforcement, but the crack of CRCP can continue to keep being in close contact, and split
Seam width very little, it is ensured that the transmission of load, prevents rainwater from invading the advantages such as corrosion reinforcing bar and being favored by engineers, but
Connection between conventional CRCP and floorings be all by hazard to bridge's pier or plate of leading the way, as its three separately designs construction,
The road surface installation grappling of leading the way after each Abutment Back of having to because of the difference such as its rigidity, construction, each end of the bridge are connected with leading the way
Place arranges retractor device；Thus, although lead the way plate and floorings, CRCP connecting portion of short time will not occur larger damage
Bad, but of long duration after, due to shrinking, creeping, the reason such as thermal strain, subgrade settlement and the stress caused by traffic loading, meeting
It was found that end of the bridge and the retractor device destructible that leads the way between plate, produce vehicle bump at bridge ends；Meanwhile, plate of leading the way is connected with CRCP grappling
The place of connecing easily occur concrete partial fracture, frangible etc. damage, not only affect integrally-built durability, and increase total life
Life cycle later maintenance expense；For the above harm, engineers carry out strengthening the common nothing of construction to the three junction
Seam treatment of road surfaces（Concreting, and arrangement of reinforcement are directly adopted, and relative dimensions are by rule of thumb）, although preferably work can be played in short-term
With, but only limitation experience remains a need for putting into substantial amounts of manpower, financial resources to its later maintenance.
