Abstract :Sleeps west Huai high speed Huai An to exchange ties salt river bridge total length 577.04m. The bridge surmounts the Huaiyin area domestic salt river. The cross salty river bridge main span uses 80+140+80m three cross variable cross-section prestressed concrete continual box Liang. The approach span uses 30m completely constant section partial prestressed concrete combination box Liang, the bridge opening arrangement carries on the control according to bridge head depth of fill H=6.0m about. And toward sleeps west Huai high speed Huai An to exchange the direction approach span bridge span arrangement for 6×30m, a six association, after first simple support, continuously; After the Huai An urban district direction approach span is as soon as three unite the first simple support continuously partial prestressed concrete combination box Liang, the bridge span arrangement for 3×30m. Goes on stage the beginning, they proposed “by the first-class management, constructs the first-class project, unfolds the invincible army elegant demeanor” the slogan, established has improved the strict rules and regulations, drew up has guaranteed superior, argued vigorously the country superior quality objectives.

Has only used 15 days, completed the entire line standard to be highest, equipment excellent test chamber, and first through Development organization's approval. 20 days completed the project department near to suppose the duty, one month has completed 11 kilometers access roads and 4 temporary bridge's construction works, took the lead to pull open the drill hole pile and the roadbed construction prologue in the entire line, in the Development organization organized in the construction earlier period preparatory work inspection obtained first, slept the Huai Highway Headquarters to hold on-the-spot meeting in this sign section, requested the entire line Construction to study to them. Key word: Prestressed concrete continual box Liang constructs earlier period preparatory work the drill hole pile soft base processing arch of bridge construction
