The prefabrication of the piers and abutments of the Second East Passage in Xiamen started the first construction廈門第二東通道墩台預制開始首件施工(gōng)

　　Recently, the prefabrication yard of Xiamen Second East Passage Project started the construction of the first pier and abutment. The construction personnel on site methodically installed templates and erected steel bars.

    近日，廈門第二東通道工(gōng)程預制場開始首件墩台施工(gōng)，現場施工(gōng)人員有條不紊地安裝模版、搭設鋼筋。

　  Xiamen Second East Corridor Project is a provincial key project. Its sea-crossing bridge section follows the construction concept of "factory, large-scale, standardized, and assembled". The substructure adopts large-scale prefabricated piers. It is the second cross-sea bridge project in China and the first in our province that adopts the vertical dry joint matching prefabrication method. Among them, the prefabrication of piers and abutments is the key process of the entire project. A total of 35 prefabricated piers and abutments are required, divided into 83 components, and the prefabrication period is 18 months.
     廈門第二東通道工(gōng)程爲省重點項目，其跨海橋梁段遵循“工(gōng)廠化、大(dà)型化、标準化、裝配化”的建設理念，下(xià)部結構采用裝配式大(dà)型預制墩台，是除港珠澳大(dà)橋外(wài)國内第二個、我(wǒ)(wǒ)省首個采用豎向幹接縫匹配預制工(gōng)法的跨海橋梁項目。其中(zhōng)，墩台預制爲整個項目的關鍵工(gōng)序，共需預制墩台35座，分(fēn)爲83個構件，預制工(gōng)期爲18個月。

　  In view of the difficult installation and protection of epoxy steel bars in prefabrication construction, the high requirements for temperature control and crack resistance of mass concrete, the difficulty in pouring and vibrating ultra-high concrete, and the high requirements for vertical matching of dry joints in prefabrication accuracy, since mid-April , the Provincial Transportation Quality and Safety Center will go to the front line to supervise and disclose the project, carry out legal popularization and technical services for quality and safety management, quality engineering creation, construction of a strong transportation country, etc., and timely convey the latest industry regulations for road and water transportation construction.

     針對預制施工(gōng)需解決環氧鋼筋安裝及保護難度大(dà)、大(dà)體積混凝土溫控抗裂要求高、超高混凝土澆築振搗難度大(dà)、幹接縫豎向匹配預制精度要求高等技術難題，4月中(zhōng)旬以來，省交通質安中(zhōng)心下(xià)沉一(yī)線對項目進行監督交底，對質量安全管理、品質工(gōng)程創建、交通強國建設等方面開展普法宣傳和技術服務，及時傳達公路水運建設最新行業規定。（省交通質安中(zhōng)心、廈門路橋建設集團有限公司）
