超大截面矩形盾構機在滬亮相

   超大截面矩形盾構機在滬亮相 地下施工不用挖開馬路“處女航”挖出臨空園區28米長隧道
   建地鐵用的盾構機通常都是圓的,你見過用矩形的盾構機來掘進地下隧道嗎?近日,上海虹橋臨空園區10-3、11-3地塊地下連接通道工程,歷時20余天,由上海建工集團自主研發的地下空間新型非開挖利器--國內首臺土壓平衡超大截面矩形盾構機首推完成。該通道建成后,將連接鄰近商務樓地下二層車庫的交通。
   昨天,記者在現場看到,這臺盾構法掘進的超大截面“矩形盾構機”,橫截面為10.1米×5.3米,頭部由8個大刀盤和3個小刀盤組成軸向伸縮式刀盤,通過交錯旋轉可形成無盲區施工,近似實現全斷面切削,邊邊角角都能照顧到。
   研發人員開發的一整套從管片設計、管片運輸到管片自動拼裝適用于矩形盾構的管片機械化拼裝技術。這一系列創新技術的運用,確保了超大截面矩形隧道結構的穩定和矩形盾構機的順利推進。貫通后的矩形隧道無滲漏,最大變形量完全處于允許的范圍之內。目前,矩形盾構機及矩形隧道創新技術已申請國家專利30項,具有完全的自主知識產權。
   超大截面矩形盾構機的“處女之航”開掘出的斷面為9.75米×4.75米的近似矩形的地下連接通道,長28米,位于上海虹橋臨空地塊的福泉北路,下穿1.8米雨水、給水、電信、電力、燃氣等7條管線。如果采用明挖法施工,不僅管線搬遷費用高昂,延長工期的同時也會妨礙園區交通的正常運行。使用矩形盾構機開挖隧道后,可免去遷移管線費時費力的困擾,確保工程如期完工。在這次掘進過程中,福泉北路地面繁忙的交通通行如常,地下低噪音施工也把對緊鄰商務樓的影響降到最低。
    與傳統的圓形盾構開掘出的圓形通道上下兩端浪費比較大相比,矩形盾構施工的空間利用率可提升20%以上,可淺覆土長距離曲線掘進,掘進施工時對周邊環境影響小,填補了國內隧道工程建設中的空白,將對國內大城市主干道下穿隧道、地下管線密布區地下通道特殊節點的處理,以及建筑物間地下連接通道建設等產生示范效應和深遠影響。
   在虹橋臨空園區地下連接通道工程“小試牛刀”后,這臺超大型矩形盾構機將投入到虹橋商務區與中國博覽會綜合體地下人行隧道東段工程的施工。
