大运河传媒讯 （董明 桂艳 发自广西桂林）“平陆运河建设是一项极其复杂的系统工程，正因为复杂，难题接踵而至，我们在闯关中摸索出一套套属于自己的解法。”10月15日，2026年世界运河大会在广西桂林闭幕。作为西部陆海新通道的骨干工程，平陆运河2022 年 8 月开工，今年9月 16日建成通航，用整整四年时间，为西南地区打通了一条出海最便捷、最经济、距离最短的国际水运大通道。会上，平陆运河集团党委书记、董事长王劼耘分享了克服建设平陆运河挑战背后的六大关键技术创新。Grand Canal Media News (Dong Ming, Gui Yan, from Guilin, Guangxi) “The construction of the Pinglu Canal is a highly complex systematic project. It is precisely because of its complexity that numerous challenges arise. Through trial and error, we have developed our own solutions.” On October 15, 2026, the World Canal Conference 2026 concluded in Guilin, Guangxi. As a key project of the Western Land-Sea New Corridor, the Pinglu Canal began construction in August 2022 and was put into operation on September 16 this year. Over a full four years, it has created the most convenient, cost-effective, and shortest-distance international water transportation route for the southwestern region. At the conference, Wang Jieyun, Secretary of the Party Committee and Chairman of the Pinglu Canal Group, shared six key technological innovations that helped overcome the challenges associated with the construction of the canal.
高水头省水船闸高效安全运行技术。马道枢纽的水头高度接近 30 米，要在这样的三级省水船闸里实现水资源节约与通航效率兼得，本身就是一对矛盾。我们对省水池的布置形式、复杂高效的输水系统做了深入研究，拿出了针对性方案；又针对大型平面闸门做了 1:1 的实体模型试验，研发出缓冲装置，终于攻克了大型闸门快速启闭的耐久与安全难题。Technologies for the efficient and safe operation of high-head water-saving lock systems. At the Ma Dao Hub, the height of the waterhead is approximately 30 meters. It is a contradiction to achieve both water conservation and navigation efficiency in such three-level water-saving lock systems. We conducted in-depth research on the layout of water-saving reservoirs and the complex yet efficient water delivery systems, and developed targeted solutions. Additionally, we conducted 1:1 physical model tests on large-scale flat gates, and created buffer devices. Finally, we managed to overcome the challenges related to the durability and safety of rapid opening and closing of large gates.
船闸大尺度复杂结构混凝土长寿命的关键技术。马道枢纽、企石枢纽的三级省水船闸廊道密布，像地下宫殿，异形结构多，怎么解决温控及混凝土的长寿命问题，我们首次提出 130 年的混凝土控制指标体系，从材料到工艺层层攻关，解决了大型复杂结构的开裂风险。Key technologies for ensuring long service life of concrete structures in large-scale, complex lock systems. At the Ma Dao Hub and Qishi Hub, there are many three-level water-saving lock corridors. These structures resemble underground palaces with various irregular shapes. To address issues related to temperature control and the long service life of concrete, we proposed a 130-year concrete control system. By addressing issues at every level—from materials to construction techniques—we were able to reduce the risk of cracking in large, complex structures.
运河环境低影响的建设技术。平陆运河跨流域、跨区域，26 条支流先后汇入。支流横向冲击影响行船、泥沙冲入威胁航道，我们研发了支流口汇入消能与泥沙协控装置，把这两个隐患一并化解。途经红树林生态保护区、饮用水源等高度敏感区域，我们又研制出成套疏浚装备，严格控制悬浮物扩散，守护一河清水。青年枢纽地处潮汐河段，上游正是钦州取水口，我们最终圆满解决了取水口防咸的问题。Construction techniques that have minimal impact on the canal environment. The Pinglu Canal spans different basins and regions, with 26 tributaries flowing into it. The tributaries can cause disruptions to navigation and pose a threat to the waterways due to sediment. We developed devices to mitigate the effects of these tributaries and control sediment levels, thereby eliminating these problems. As the canal passes through mangrove ecosystems and areas with high sensitivity regarding drinking water sources, we also developed a set of dredging equipment to control the spread of suspended particles, ensuring clean water in the river. The Qingzhou Hub is located in a tidal area, with the Qinzhou water intake nearby. We successfully addressed the issue of salt intrusion at the water intake.
高密度桥梁群拆建的协同技术。平陆运河全线有 27 座跨运河桥梁需要拆建，仅钦州城区段 8.3 公里范围内就集中了 8 座。拆桥容易，但必须保证原有交通不断行。我们的思路是先修保通桥保障通行，再拆旧桥、建新桥，新桥通车后再撤掉保通桥。城市施工空间狭小、安全环保要求高，我们就在设计方案、施工方案、交通组织上反复打磨，最终让施工与城市正常运转两不误。Coordinated technologies for the dismantling and reconstruction of high-density bridges. There are 27 bridges across the Pinglu Canal that need to be dismantled or rebuilt. In the 8.3-kilometer area around the Qinzhou urban area, 8 such bridges are located. Dismantling bridges is easy, but it is essential to ensure continuous traffic flow. Our approach is to first build bridges that maintain traffic flow, then dismantle the old bridges and build new ones. After the new bridges are operational, the bridges that maintained traffic flow can be removed. Given the limited space and high safety and environmental standards in urban areas, we carefully refined our design plans, construction methods, and traffic arrangements, so that construction can proceed without disrupting urban operations.
巨量土石方的快速处置与资源化利用。平陆运河建设中，3.15 亿立方米的巨量土石方的处置利用，是我们一个大的科研课题。从土质快速识别、挖运方案、分类处置，到资源化利用、堆填方式、表土改良复垦，我们打通了全链条，最终实现了 98% 的综合利用率 —— 让工程开挖的渣土变成了可再利用的资源。Rapid disposal and resource utilization of large amounts of soil and rock materials. During the construction of the Pinglu Canal, the disposal and utilization of 315 million cubic meters of soil and rock materials represent a major research project for us. From the rapid identification of soil properties, excavation and transportation plans, classification and disposal, to resource utilization, landfill methods, and soil improvement and restoration, we have established a complete chain of processes. As a result, a comprehensive utilization rate of 98% was achieved – allowing the waste from the construction work to be turned into reusable resources.
全生命周期的智慧运河关键技术。我们构建了决策智能、管控精准、安全可靠、服务高效的智慧运河体系，覆盖智慧建造、智能运维、智能监测、智能航行、智慧物流、智慧服务六大场景。依托平陆运河项目，我们联合院士专家团队开展技术攻关，承担了 41 项国家级、省部级科研项目，创造了多项世界和国内之最。Key technologies for an intelligent canal throughout its entire lifecycle. We have developed an intelligent canal system that features intelligent decision-making, precise control, safety and reliability, and efficient service. This system covers six main areas: intelligent construction, intelligent operation and maintenance, intelligent monitoring, intelligent navigation, intelligent logistics, and intelligent services. Based on the Pinglu Canal project, we have worked together with academic experts to carry out technical research, and have undertaken 41 national and provincial-level scientific research projects. We have also set several records both in the world and at the domestic level.
平陆运河为重塑中国水网布局开了新篇，也推动着广西现代水网协同建设迎来新高潮。更重要的是，这条新通道还将重构中国与东盟的产业链、供应链与价值链，为区域经济发展打开一扇全新的大门。The Pinglu Canal has opened up new possibilities for reshaping China’s water network structure. It has also promoted the coordinated development of modern water networks in Guangxi. More importantly, this new channel will also reshape the industrial chains, supply chains, and value chains between China and ASEAN countries, opening up a whole new path for regional economic development.
