　　深中通道E32管節實(shí)體浮運演練

深中通道E32超寬變寬管節完成實(shí)體浮運演練，預計8月在深中通道東側沉放對接安裝。E32管節與東人工島島頭堰筑段對接，是沉管隧道的首個(gè)非標準管節。

E32管節作為超寬變寬曲線(xiàn)沉管管節，管節型長(cháng)超過(guò)120米，型寬由53.6米漸變至55.46米，最寬處可達雙向10車(chē)道。本次實(shí)體演練中，E32管節從廣州南沙龍穴島船廠(chǎng)浮運至廣州港后原路返航，單程總里程6.072公里（3.28海里），項目部組織船組按計劃分別進(jìn)行了沉管進(jìn)出港池、180度回旋掉頭、橫流浮運、模擬隧址系泊、順航道浮運、回拖等多項科目演練。面對復雜、狹窄的演練區域，拖輪編隊如同“穿針引線(xiàn)”般精準操控，特別是在港池內將E32管節沿港池中軸線(xiàn)以偏差不超過(guò)5米的精度完成了進(jìn)出港池操作，僅用四條拖輪即在前后左右僅10米范圍內完成了模擬隧址系泊科目演練，大幅刷新了拖輪編隊操縱精度。（來(lái)源：深圳特區報）
