武漢地鐵5號線又一區間隧道雙線貫通

3月12日上午,武漢軌道交通5號線新生路站至三角路站區間(新三區間)左線盾構機緩緩剝離洞門最后一層混凝土,意味著新三區間隧道雙線勝利貫通。

 

 

新三區間與長江、沙湖交織相連,且與長江同向布設, 因此1252米長的盾構段掘進過程非常考驗工藝工法及參數控制。

 

難點一  水文地質極其復雜

新三區間剖面形態如同“人”字形,盾構機從新生路站出發以3‰的坡度爬至線路最高點,緊接著以5.98‰坡度“俯沖”至三角路站進洞接收。

 

同時,區間地質結構復雜,需要穿越軟硬不均、大量粉砂、超淺埋覆土等不良地質。

 

盾構區間多為高壓塑性土層,地下水十分豐富,地層反應靈敏,土體抗剪強度低,工程性能差,容易發生突泥涌水、泥土結餅等問題。以上均對盾構掘進姿態、隧道管片上浮下沉控制、地表沉降控制具有極大的挑戰。

 

項目部嚴格遵從設計方案,組織3臺三重管攪拌機耗時整整3個月時間,在地面對淺埋地層段進行土體改良,有效保證了盾構機掘進的穩定性和安全性。

 

難點二  上跨長江公路隧道

新三區間隧道與長江公路隧道正交,左右雙線均上跨長江公路隧道。

 

項目部專門組織技術力量提前編制施工方案、監測方案、應急預案等,并先后三次組織專家會進行論證和會審,積極主動與長江隧道管理單位對接。在跨越武漢長江公路隧道過程中,項目始終遵循“嚴控參數、緊密監測、加強巡視、強化信息、勻速推進”的20字方針,保證掘進指令執行到位和設備運行安全。

 

項目部全體工作人員100多個晝夜如履薄冰,今天新三區間雙線盾構機終于全部安全穿越成功完成接收,這個重要的工程節點來之不易。

 

5號線工程進展

武漢軌道交通5號線全長33.57公里,設站25座(地下站21個,高架站4個),目前新生路站、武鋼站等5座車站主體結構完工,楊園站至余家頭站等6個單線盾構區間實現貫通,高架區間全部在建。
