10月12日,三峡枢纽新通道先行开挖区巨大的基坑内,电动重卡往来奔忙;雾炮持续喷出水雾,抑住扬尘;护坡格构整齐排布,绿植破土而出。
该项目位于三峡枢纽新通道上游引航道末端,长约935米。三峡枢纽新通道工程管理部主任宫照光告诉记者,作为三峡枢纽新通道施工的“试验场”,先行开挖区已圆满完成全部爆破开挖任务,目前正开展出渣和支护工作,环保管控始终贯穿施工全流程,为后续工程绿色施工积累了宝贵经验。
土石方资源化循环利用是项目绿色施工的一大亮点。宫照光介绍,先行开挖区项目累计完成土石方开挖近800万立方米,这些石料会先分类,适宜利用的将转化为工程建设资源。
“先行开挖区剥离了近20万立方米表土,我们分区堆存在堆场。等施工结束,这些珍贵的熟土将重新用于场区和渣场复绿,实现土壤资源的循环再利用。”宫照光说。
水资源同样实现闭环循环。宫照光表示,施工现场砂石加工和车辆冲洗产生的废水经过处理后用来洒水降尘、浇灌植被,“不让一滴污水流入长江。”
在污染管控方面,项目搭建起全链条扬尘防控体系,现场布设10座洗车池及冲洗平台,配备约20台洒水车持续降尘;砂石车间全封闭作业,配套除尘、喷淋装置,全域推行湿法施工、裸土覆盖、密闭运输,精细管控施工污染。
在节能减排方面,项目推行绿色运输,实现低噪零排放。水电四局新通道项目部副经理朱四辈介绍,开挖区投用40台纯电动重卡,运行噪声控制在60分贝以内,较燃油重卡能耗下降40%以上,目前已累计减排二氧化碳约2960吨。
宫照光表示,依托一系列绿色创新实践,先行开挖区为重大水利工程实地打样,探索工程建设与长江生态保护共生共赢的可行路径。
三峡水运新通道工程是“十五五”期间开工建设的首个国家重大标志性工程,由三峡枢纽新通道和葛洲坝航运扩能两部分组成。其中,三峡枢纽新通道位于已建三峡船闸北侧,规划新建双线连续五级船闸,线路长约6680米。

Traditional industrial enterprises such as Fangda Special Steel and Jiangzhong Medicine Valley in Nanchang, Jiangxi, have achieved green transformation through environmental protection investment and circular economy. The former heavily polluted factory areas have been transformed into national 4A-level tourist attractions and ecological forests, reflecting Jiangxi's effectiveness in promoting green and low-carbon industrial development.

The Central Meteorological Observatory issued a marine weather bulletin on October 12, stating that affected by strong winds and localized fog, windy weather of varying degrees will occur in the Bohai Sea, Yellow Sea, South China Sea and other offshore waters in the next few days, and reminded ships in relevant sea areas to pay attention to safety.

The New Taipei City Environmental Protection Bureau holds the 12th Love Heart Flea Market "Christmas Environmental Treasure Hunt", which will be held on November 21. From now until November 13, the "Good Things Set Sail" second-hand goods collection order is launched, calling on the public to donate unused items at home for charity sales, and all proceeds will be donated to the disadvantaged.

Guangyang Island in Chongqing was once ecologically damaged due to over-development. Since commercial development was suspended in 2017 and a systematic project of "natural restoration as the mainstay, artificial restoration as the supplement" was implemented, it has restored its beautiful ecological scene and has become a successful example of biodiversity protection and ecological restoration in the Yangtze River Basin.

On October 12, cold air affected northern my country, causing rainfall in North China, Northeast China and other places. In the next few days, as cold air moves southward and combines with warm and humid air, there will be heavy rainfall from the southwest to the middle and lower reaches of the Yangtze River, which will be extreme in local areas. The public needs to be on guard against geological disasters.

The Sichuan Provincial Government Information Office held a press conference on the 12th to introduce the achievements of the fifth anniversary of the construction of the Sichuan area of the Giant Panda National Park. Gu Xiaodong said that the area relies on natural landscapes and relics, with an average annual ecological experience of more than 3 million people, and achieves a balance between strict ecological protection and public welfare sharing.
