南洞庭大橋首套斜拉索準備掛設

斜拉索上半部分固定完成


7月3日,經過8個小時的奮戰,南洞庭大橋首對斜拉索掛設完畢。益南公司經理歐陽心和及集團副總經理、總工程師盛希參加了鋼箱梁安裝工程施工專題協調與推進會,并到施工現場對斜拉索準備工作及施工安全進行現場督導。

施工前,項目部組織技術人員反復討論,制定了完備的施工方案,對施工作業人員進行了嚴格的安全交底和技術交底,確保萬無一失。斜拉索掛設開始后,施工作業人員通力協作,將吊索運送至指定位置,熟練地操作放索架、展索,然后通過索塔頂塔吊、卷揚機、滑輪組及鋼絲繩進行“穿針引線”。作業人員精益求精,不放過任何一個細節,確保了掛點牢靠、定位精確。

本次南洞庭大橋首對斜拉索掛設安全、優質、高效,各項技術參數達到預期目標,為以后斜拉索掛設積累了寶貴經驗,也為大橋年底全線具備通車條件打下了扎實基礎。(長江分公司  謝樂)


【施工背景簡介】

南洞庭湖大橋作為南益高速的控制性工程,是目前湖南省內第一大跨徑雙塔雙索面斜拉橋。斜拉索是南洞庭大橋的重要組成部分,斜拉索標準索距為12m,加密區為5m,每個索塔兩側各布置17對,全橋共68對(136根)斜拉索。斜拉索主梁上采用錨拉板構造錨固,塔上采用鋼錨梁構造錨固,張拉端設計在塔端。斜拉索采用抗拉標準強度為1770mpa平行鋼絲斜拉索,斜拉索護套采用彩色高密度聚乙烯材料,斜拉索錨頭為冷鑄錨,根據索力的不同,采用PES7-85、PES7-109、PES7-127、PES7-151、PES7-187五種規格,拉索最長無應力索長237.53m,單根拉索平行鋼絲最大重量約為15t,屆時重達1.3萬多噸的鋼箱梁重量將被拉起。
