“FAXX和MAXX”广西龙门大桥通车FAXX和MAXX 红树林保护举措有成效

  中新FAXX和MAXX网钦州12月29日电(翟李FAXX和MAXX强)12月29日,广西交通投资集团投资建设的龙门大桥项目顺利通车,大桥横跨西部陆海新通道骨干工程——平陆运河的出海口,穿越广西钦州七十二泾风景区,与桥下的蚝排、郁郁葱葱的红树林、星罗棋布的绿岛相映成画。

  龙门大桥是广西首座千米级跨海悬索桥,是国道G228丹东至东兴广西滨海公路主线的重要组成部分,项目路线全长7.637公里,穿越钦州茅尾海红树林自然保护区边缘及七十二泾风景区,涉及红树林范围广。如何与红树和谐相处,是龙门大桥建设的重点工作之一。在建设过程中,项目团队采取了多种举措对红树林进行保护,并取得了成效。

  据广西交通投资集团介绍,为最大程度降低对红树林的占用,通过调整龙门大桥最初的设计路线,不惜增加约5亿元投资,避开茅尾海红树林核心保护区。同时,将现浇箱梁改为预制小箱梁,取消承台,改为桩基接墩柱设计,保护了约17000株红树林不被破坏。

  在建设过程中,项目团队还创新性移植扬帆立交施工区域永久占用红树林1120余株,包括桐花树、秋茄及白骨壤三个树种,林龄均超过30年;采取“插针法”搭建施工钢栈桥,实现钢栈桥范围内红树林零砍伐;引入红树林人工补光、模拟人工降雨、坡脚及边坡防护等措施,还原红树林原生长环境;设置红树林敏感区观测点,动态跟踪监测红树林生长状况;积极落实红树林生态恢复工作,完成项目红树林FAXX和MAXX异地恢复补种4.44公顷。红树林保护取得国家发明专利2项,牵头制定广西地方标准1项。

  作为北钦防一体化的重大基础设施支撑项目,龙门大桥的通车意味着广西滨海公路的“卡点”被打通,将防城港与钦州港的行车时间由原来的1.5小时缩短至25分钟左右,有力促进北钦防一体化和北部湾经济区高质量发展,助力西部陆海新通道建设。按照规划,广西滨海公路将建成“车在海边走,人在画中游”的景观大道,龙门大桥无疑是最精彩的一段。(完)
