海太长江隧道一头连着南通海门,一头连着苏州太仓,总长11.185公里,其中盾构段就有9.315公里。它也是目前世界上最长的公路水下盾构隧道。这个国庆假期,隧道的施工进展如何?来看总台记者从施工现场发回的报道。

总台记者 唐高林:现在我所在的位置,是在长江江底之下30多米深的施工现场。在我身后,就是正在掘进的“江海号”盾构机。国庆假期,这里仍有600多名工人奋斗在一线,确保施工如期推进。

先简单介绍一下这条隧道的基本情况:它一头连着南通海门,一头连着苏州太仓,是目前世界上最长的公路水下盾构隧道。 整个隧道是双向六车道设计,分左右两个独立隧洞,两条线的开工时间相隔四个月。先开工的是右线,就是我现在站的这条线。“江海号”盾构机的作业面,目前已经到了8000米的位置;左线的“沧渊号”刚刚顺利通过水面下75米深的最低点。这也标志着,这一前一后、一右一左两条线,全都闯过了整条隧道水压最高、风险最大、地质最复杂的关键段落。

为什么左右两条隧洞不一起开工,非要一前一后错开呢?现场的技术人员告诉我,海太隧道的施工条件,业内人员总结叫“四超”:超长距离、超大断面、超高水压、超大埋深。在水面下75米的最低点,盾构机正面顶着的水土压力能达到7.5巴。这个压力相当于每平方米的地面上,压着大约51辆的小轿车。

这么大的压力,要是两台盾构机同时开动,江底的地层会被反复扰动,施工风险也会变高。所以两条线必须拉开足够的时间差和空间距离。这样做还有一个好处,就是前面的盾构机在施工中遇到的难题和积累的经验,都可以共享给后面的班组,这样施工效率和安全系数大大提高。

工欲善其事,必先利其器。再给大家说一下超级装备——盾构机。以我身后的“江海号”为例,它的直径有16.64米,差不多五层楼那么高,我们现在,其实是在它的“肚子”里面。

整台盾构机分成前面的刀盘、中间的盾体,后面的配套设备。技术人员跟我说,盾构机不光个头大,还搭载了多项国内外首创技术。最前面的刀盘转动起来,就能够轻松打碎前方的泥土砂石。

这是一把撕裂刀模型,真实刀具是用合金打造的,重量达到400斤。它不光力气大,还特别“聪明”。大家看刀具中间这个黄色部件,是一个实时监测传感器。当掘进的时候,刀具的转速、土层的硬度、磨损情况等,所有数据都会适时回传到后台,工程师盯着屏幕就能掌握掘进状态,从而保证盾构机走得稳,不跑偏。

隧道建好之后,整个隧道分成三层:最上面是排烟的烟道层,中间是行车道,最底下一层分成三块,分别是管线廊道、疏散通道和逃生楼梯间。以后万一隧道里出现突发情况,人员可以顺着逃生楼梯下到底层,乘坐救援车快速撤离,这个设计是国内首创的救援车专用通道。

按照计划,海太长江隧道2028年基本建成。整个南通区域内,166公里的长江岸线上,有8座过江通道,也就是当地所说的“八龙过江”。未来,这里开车过江只需要10分钟,从海门出发半个多小时就能到上海市区。海太隧道的建成,对于推动长三角一体化和跨江融合发展具有重要意义。

高铁新线开通 奔赴森林的“快”进“慢”游

重大工程落地,也会重塑一个地方的旅游版图。这个国庆假期前夕,哈伊高铁正式开通。这条新高铁,也正在催生伊春“快”进“慢”游的文旅新热潮。

从哈尔滨出发,一路向北,直入小兴安岭。车窗外刚刚掠过黑土粮仓,转眼便是万顷松涛林海。

旅客 宋宝珍:开阔,连绵起伏,这一路上都是景,特别快乐。

不少游客一到站,先去租辆车。伊春西站周围,几家原本主营二手车销售的门店也主动转型,把车辆和场地投入旅游接待,抢抓文旅新机遇。

游客 李怡君:我们在伊春本地租车,四五天时间,就能把伊春的核心景点游览一遍。

国庆假期期间,正是小兴安岭秋色最盛的时候:汤旺河奇石彩林交相辉映,金祖峰日出云海霞光万丈,茅兰沟潭水倒映着五彩斑斓的秋色。伊春溪水国家森林公园今年新栽植荷兰菊等观赏花卉,花海与五花山色相融。

商户 张磊:不少游客看完五花山,顺便选购山货,销路一下子打开了。

一条高铁缩短时空距离,东北边疆高铁路网布局加快完善,沿线也被持续激活。

伊春市溪水林场养顺农家院负责人 吴文丽:一直忙活到晚上。高铁通了以后,感觉人一下子多了。

与此同时,民宿集群、康养旅居、林间小院等新型住宿业态,也在当地快速崛起。

伊春市文化广电和旅游局副局长 王晓微:哈伊高铁打通伊春对外联通的交通瓶颈,我们做强“高铁+生态旅游”模式,持续完善吃、住、行、游、购、娱全链条配套。

新开的高铁线拉近远方与山水的同时,也正在不断激发着新的消费活力:数据显示,国庆前夕,雄商高铁、西康高铁、宜兴高铁、哈伊高铁4条新线集中开通,穿越华北、西北、华中、东北,带动沿线酒店预订量同比增长均超20%,还有一批沿线小城正尝试接住高铁带来的新流量:陕西安康面向游客推出围绕高铁票的票根经济礼包;湖北兴山借高铁加速让土特产出山;黑龙江铁力则加紧建设新的游客集散中心。

高铁飞驰穿山越岭,打开新的发展空间。

海岛追风 绿色能源基地变旅游打卡地

“十五五”期间,东海等海域的海上风电基地建设,正在加快推进。位于东海之滨的福建平潭,这座海岛上的“大风车”,眼下不仅向外输送绿电,这个国庆假期也吸引来许多游客。绿色能源基地,现在成了假期里的热门旅游打卡地。

总台央视记者 刘柏煊:到了下午,气温稍降,在平潭这条环岛公路上,车流和人流慢慢聚集起来。今年的国庆假期,这里首次启用潮汐车道,高峰时单向一车道变成两车道,更加方便游客的出行和观光。

游客 李彦臻:从网上看到这个照片觉得很美,一下子就过来了。

游客 花浩然:大国制造和景点结合起来,让我感到很自豪。

游客 曹大东:一列一列的风机,感觉很壮观,也很酷。

国家电网平潭供电公司运维技术员 李善烜:我们平潭全年有200多天都是大风天,现在我们海上、陆上风机一共有200多台,每隔几百米,就能看见我们转动的“大风车”。

总台央视记者 刘柏煊:走上环岛公路,这个拐角处,反倒是人气最高的一个点位。转角的一瞬间,视野豁然开朗,整片的大海和成片的风车,直接扑面而来。

除了近岸的“风车海”,平潭还坐拥陆上的“风车森林”,陆上风机错落地分布在乔木林中,这里又是另一种玩法:游客在这里徒步、登高,可以近距离置身“大风车”底下。

游客 赵雨:尤其是近观以后,震撼感更加明显,大国重器给我们的一种力量感。

伴随“风车”旅游线路向森林深处延伸,今年以来,一系列靠山面海的消费空间,也在沿途不断“生长”起来。

福建平潭,一度因为风大而难以留住游客;而现在,这座海岛因为“风车”景观,迎来新的“风口”。

平潭海上风电场工作人员 孙中昊:我们这两列风机,基本上就沿着海岸线分布,有大有小、有疏有密,在考量到经济性、安全性的前提下,也打造一个立体的、有层次的“风车”布局。

平潭综合实验区旅游与文化体育局副局长 欧阳桢:我们正在持续丰富“风车”系列文旅产品,推出滨海追风、风车主题旅拍,策划特色“风博物馆”等,把“风车”变成一条可看、可玩、可学的文旅线路产品。

“Panda Diplomacy” from Nixon to Trump-Xi Summit: The Tension between Symbolic Meaning and Strategic Reality

Chinese giant pandas "Ping Ping" and "Fu Shuang" arrived in Atlanta, United States, on September 27, beginning a ten-year stay. When Xi Jinping announced the matter at the White House, he called the panda an envoy of friendship between China and the United States. The article points out that although panda diplomacy was once a tool for Beijing to create a friendly image, competition between China and the United States has now extended to areas such as technology, trade, and military affairs, and the symbolic significance of pandas has been questioned. Taiwan should be wary of hard power competition behind soft diplomacy.
