中新网北京10月18日电 (记者夏宾)近日，中国地下工程装备研制取得重大突破——由中交天和自主研 制、用于山东枣庄山亭抽水蓄能电站地下工程开挖直径6.53米的"墨子号"双护盾硬岩掘进机(TBM)下 线。"墨子号"凭借全球"最小转弯半径"技术，刷新同类(6米级)地下掘进装备技术极限。 山东枣庄山亭抽水蓄能电站地下工程，堪称"地下迷宫大冒险"。地层结构犹如千层酥，既分布坚硬的石 灰岩，夹杂松软的页岩，还暗藏溶洞、断层和地下水，掘进时稍有不慎就可能遭遇塌方或涌水险情。 而更大挑战在于掘进路线曲折复杂，"墨子号"需在3.25公里深层地下，完成高难度"花式走位"，从顶拱 中导洞出发，返回上层排水廊道岔口后进入上游排水廊道，沿斜坡一路向下穿越交通洞，再转入尾水隧 洞支洞，先后穿越2号、1号尾水隧洞，最终从下水库进出水口"破土而出"，一路需完成包括60米极限半 径在内多个急转弯(相当在标准泳池完成U型掉头)，堪称TBM掘进"花样滑冰"。复杂的转场路线和极限 转弯半径，在全球同类工程中属首次。 面对连续急转弯带来的"卡壳"、排渣不畅乃至"迷路"风险，中交天和研发团队为"墨子号"打造系统性解 决方案，确保在深地空间灵活穿行、精 ...
