The use of pile construction tenders back to the island as a construction platform filling , backfilling from Z0 to Z33 pier , with the construction of access roads and building island platform construction is completed, from north to south successive pile construction commenced .
Island built backfill construction, drilling pile construction , pile reinforcement cage installation
(2) cap construction
The tenders are rectangular pile separation structure , in addition to the bridge approach abutments Z0 cap thickness 2.5m, other Z1 ~ Z30 Approach No. cap thickness are 4m, Approach No. Z31 main bridge pier cap handover thickness 5m, the main bridge Z32, No. Z33 cap thickness are 6m, except Z0 cap pouring concrete once completed , Z1 ~ Z33 No. pile of 2-3 times pouring completed . Pile construction platform using reclaimed land back to the island to promote the construction , Z0 ~ Z12 form using open-cut excavation , the rest were using steel sheet pile cofferdam sealing process .
The main bridge steel sheet pile injections , the main bridge purlin steel sheet pile construction , pile template installation .
3 pier construction

Pouring concrete on using the full framing construction technology .
Full Support situ beam construction, installation and construction of cast steel beams , concrete pouring cast beam construction, the construction is completed in-situ concrete beams .
8 bridge deck construction
Bridge deck construction including C40 8cm thick polypropylene fiber reinforced concrete, fiber reinforced polymer modified asphalt waterproof layer , 6cm Marty fat gravel asphalt SMA-16, modified asphalt emulsion adhesive layer 0.4 ~ 0.6kg/m2, 4cm asphalt Marty fat gravel SMA-13 and so on.
Floor system and ancillary facilities construction , asphalt paving construction , asphalt pavement rolling construction, construction finished floor system , after the completion of the whole bridge construction photos .
* General Bay Area on the 14th Road Sea Bridge project a bid in the superior leadership attaches great importance to and under the correct leadership , through the careful construction project department staff under the strict control of basic construction , substructure and superstructure construction developed effective effective construction process , making the whole part of the entry qualification rate reached 100% , the appearance of good quality . The leadership of the company and the project quality and safety department attaches great importance to the safety and quality inspectors set up a special group to strengthen on-site supervision , making the whole construction period without any safety and quality accidents.
The project was the owners of units ( ** P Bay Project Management Limited ) as 2012 annual " safety and quality standardization management demonstration site " and " Best civilized construction site ." Fully demonstrates that the owners of our highly recognized engineering , but also has been encouraging . My unit will also take this opportunity to continue to work for the general Bay for more contributions ** municipal building , I hope I'm in the municipal engineering units to more successful , my unit will continue to uphold the "intentions pouring your satisfaction " the concept of service for municipal building ** pouring more fine works .
Thank you !
