    9月5日上午,隨著盾構機刀盤緩緩從洞門處破土而出,由鄭州公司承建的鄭州市軌道交通4號線08標段貨棧街站至航海東路站右線區間順利貫通,為后續工程施工創造了有利條件。

  08標貨棧街站至航海東路站右線區間全長2055.974m,設六條平曲線、一處聯絡通道、一處聯絡通道兼泵房、一處區間風井。“開拓一號”盾構機從2017年12月30日始發,歷時8個月,成功下穿隴海鐵路、側穿世紀歡樂園摩天輪以及下穿中州大道直徑1.6米污水管等多處重大風險源。其中,在下穿中州大道直徑1.6米污水管過程中,盾構機刀盤頂距離污水管管底僅60厘米,施工難度之大為鄭州市地鐵施工首例。經項目施工人員兩天兩夜努力,最終順利完成下穿。 (朱靜)
