1—8月,全国水利建设落实地方政府专项债券、银行贷款、社会资本共3128.1亿元,其中,引入民间资本134.3亿元,同比增长80.1%。
广东省湛江市麻章区,双向四车道的雷湖快线车来车往。路面下7米多深处,一条管线横穿而过,不声不响、悄然贯通。
沿道路一侧“环北部湾广东水资源配置工程(施工D2标)”牌子所指方向,可见一口巨大的工作井。爬上一人高的井沿,再顺着窄窄的铁架子下到井底,便置身一个宽大的圆形“洞口”——并排走三四个人绰绰有余。望向“洞内”,一片漆黑,不时有对面工作井里施工、说话的回声“嗡嗡”传来。
“实际上,现在不在洞里,在管子里。这是我们为工程项目定制的大口径顶管。”广东青龙管业有限公司副总经理张宪伟一边用手势比画,一边解释,“混凝土管,一个顶一个,紧紧连接起来,为工程输水管道在地下穿行打通一条道。”
环北部湾广东水资源配置工程是国家水网骨干工程,投资规模大、输水线路长、建设条件复杂。作为民营企业,青龙管业参与了工程建设。
施工段往东50多公里,湛江吴川市黄坡工业园区,青龙管业生产车间内设备轰鸣。“这是振动器在工作,给焊接好的钢桶浇筑混凝土。”青龙管业总经理袁帅介绍。
顺着生产线往下看,一个浇筑好的圆柱体大管,正在机器里缓缓转动,让伸出来的机械爪,绕着自己4米口径的“大腰围”转圈。“这是缠丝机,混凝土外缠钢丝,缠完还要再浇筑一层混凝土。”袁帅告诉记者,这样几十吨重的大管,在这条生产线上,几个小时就能出一个。
“顶管深埋地下,适配大流量长距离的隧洞输水场景,承载内外双向压力,抗压、抗腐蚀要求高。”袁帅介绍,整套制造流程和材料参数,都是根据施工标准、环境条件专门设计,“混凝土的强度等级,钢环上焊接U型筋的角度、数量、间距等,都不能有半点大意。”
这处生产基地,专门生产PCCP(预应力钢筒混凝土管)、塑管、钢管等,已为多个工程项目供应管材超200公里。基地为环北部湾广东水资源配置工程定制的PCCP里,还专门预置了芯片。每根管的生产参数、检验信息等,动动指尖就能查询。“管材有了身份证,深埋在地下也一目了然。”张宪伟说。
青龙管业集团营销总经理王占虎介绍,紧跟重大水利工程建设,集团已在相关地区落地近30座专业化生产基地。
随着国家水网建设全面提速,行业需求集中释放,包括青龙管业等在内的广大民营企业迎来发展机遇。以环北部湾广东水资源配置工程为例,管材供应方面有来自山东的民营企业,工程服务端有上海的民营企业参与施工监理……“从管材供应到监理检测,从用地保障到数字赋能,民营企业在重大工程全链条各展所长、同频共振。”广东粤海粤西供水有限公司有关负责人说。
“水网建设持续推进,市场机会越来越多。作为民营企业,真切感受到国家重大水利工程带来的发展机遇。”袁帅认为,重大项目投资体量可观,带动上下游产业链协同发展,给企业带来实实在在的成长空间。“我们对后续发展很有信心,将持续做好技术研发、市场开拓,进一步把产品质量、供货交付能力做扎实,把企业自身发展融入国家水利建设的大局。”袁帅说。(记者 贺林平)

On September 24, the Yijing X9 was officially launched in Guangzhou. As the second-generation family flagship that is a native integration of Dongfeng and Huawei's Qiankun full stack, a total of 4 models have been launched, with limited-time rights prices starting from 279,800 yuan. The model integrates six major intelligent solutions of Huawei Qiankun and is equipped with the industry's first all-time and space security architecture "Tianqiong Intelligent Shield". It also provides three basic rights and eight limited-time rights, with a comprehensive rights value of up to 100,000 yuan.

Asian stock markets generally fell on Monday. Affected by the surge in long-term U.S. government bond yields, China's ChiNext Index fell more than 4%, and South Korean stocks fell 2.6% to fall below 7,000 points. The Nikkei Index also turned from gains to losses. Market concerns about the progress of ceasefire negotiations between the United States and Iran and expectations of U.S. interest rate hikes have pushed up global borrowing costs.

The world's most advanced 12-inch wafer foundry VSMC in Singapore held an opening ceremony. Chairman Fang Lue said that the factory will support industry growth and strengthen the resilience of the global supply chain, and thanked TSMC, NXP and the Singapore government for their support. Singapore's Minister of Trade and Industry Chen Shilong pointed out that VSMC will create 1,600 job opportunities, with a production capacity of 44,000 wafers, and a process covering special process nodes from 40 nanometers to 130 nanometers.

In May 2026, the heads of state of China and the United States met in Beijing and agreed to establish the Intergovernmental Trade Council. In September, the two sides reached consensus on the working procedures of the Trade Council, the US$30 billion reciprocal tax reduction framework and the product list during the eighth round of economic and trade consultations. The United States will reduce taxes on approximately US$30 billion of goods imported from China, including toys and home appliances, and China will reduce taxes on approximately US$30 billion of goods imported from the United States, including agricultural products and medical equipment. More than 90% of products will be exempt from all mutual tariffs and enjoy most-favored-nation status. The two sides agreed to establish an agricultural working group under the Trade Council and plan to hold its first meeting before the end of 2026 to expand practical cooperation in the agricultural field.

As the construction of "good houses" advances, the construction industry is shifting from traditional on-site construction to an industrial, digital, and intelligent factory manufacturing model. Modular buildings realize parallel production between factories and construction sites, with an all-factor module being rolled off the production line every 20 minutes on average. The Huazhang Xinzhu project was delivered in 365 days, and the construction period of the Huabichang Hutong project was reduced from 15 months to 3 months. This transformation not only improves construction speed and accuracy, but also significantly reduces waste, material loss and energy consumption. It also changes the role of construction workers from manual labor to technical operations, and robots and AI begin to be applied to production lines.

Canadian snowshoe brand SOREL will officially set up a branch in Taiwan in 2026.
