On the morning of January 30, with the slow rise of the Xijiang water intake gate on Liyuzhou Island in Shunde, Foshan, a major national water conservancy projectPearl River Delta Water Resources Allocation ProjectThe official opening of the water marks the successful completion of the water resources allocation project with the largest investment, the longest water transmission line and the widest water receiving area in Guangdong Province so far. The project has become another super project completed in Guangdong Province after the official opening of the Hong Kong-Zhuhai-Macao Bridge.

Ensure the safety of water supply in the Bay Area
The Pearl River Delta Water Resources Allocation Project is a landmark project among the 172 major water conservancy projects for water conservation and water supply in China, and has been included in the "Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area", "Outline of the National "14th Five-Year Plan", "Outline of the National Water Network Construction Plan" and other important plans, and is also an important part of the "five vertical and five horizontal" water resources allocation backbone network in Guangdong Province.
The water intake at the source of the project - Lei Yue Chau Pumping Station.
The total length of the project is 1132 km, annual water supply 170.8 billion cubic meters, benefiting more than 32 million people along the water transmission line. The project diverts water from the Xijiang River system to the eastern part of the Pearl River Delta, starting from Liyuzhou in Shunde, the main stream of the Xijiang River in the west, crossing the Shiziyang, and reaching the Gongming Reservoir in Shenzhen in the east.
The Pearl River Delta Water Resources Allocation Project is open to waterIt marks Guangdong's realization of "West Water and East Economy".It will completely change the single water supply pattern of Nansha District, Shenzhen City and Dongguan City, and provide emergency backup water sources for Hong Kong, Panyu in Guangzhou, Shunde in Foshan, etc., and gradually return the ecological water in the Dongjiang Basin, so as to fully ensure the water supply security of the Guangdong-Hong Kong-Macao Greater Bay Area.

Create a number of world bests
The Pearl River Delta Water Resources Allocation Project is an ecological and intelligent project in the new eraIt is constructed 40 to 60 meters underground by means of a deep buried shield, which is extremely difficult to construct。In the process of engineering construction, it is necessary to cross the Xijiang River three times, and the Pearl River Delta region has a dense river network, dense buildings, staggered road networks, complex underground faults, and changeable geology.
The shield tunnel crosses the bottom of the lion's ocean.
In the face of the huge difficulties and challenges brought about, in the design stage, in order to avoid important urban facilities and residential gathering areas, the engineering team crossed mountains and mountains, and did their best to keep the construction areas along the line away from the downtown area, residential areas and ecological areas. During the construction phase,The project "tailor-made" 48 large-scale shield machines for each construction section to overcome difficulties such as crossing structures, crossing mountains and waterways, opening warehouses and changing tools in complex geology, and overcoming groundwater obstacles, creating a number of firsts in the history of water conservancy construction in China and the world.
At the same time, the builders carried out scientific research and prototype tests, and worked together to overcome many world-class problems such as long-distance deep-buried shield construction, high-pressure lining design and construction, wide-lift variable-speed water pump research and development, and long-distance deep-buried pipeline maintenanceIt has created the shield tunnel with the highest water transmission pressure and the longest prestressed lining water transmission tunnel in the world, and built the world's largest long-distance pressure water transfer project.
Build smart water conservancy projects
The water transmission line of the Pearl River Delta Water Resources Allocation Project spans the core urban agglomeration of the Guangdong-Hong Kong-Macao Greater Bay Area, crossing 4 high-speed railways, 8 subways, 12 expressways, and 16 rivers, lakes and seasThe whole line adopts the method of deep buried shield pipeline, and the water pipeline is built in the underground space with a depth of 40 to 60 meters.
Gongming Reservoir officially ushered in the water of the Xijiang River.
By employing this deep water delivery method,The permanent land acquisition of the project is only 2,600 acres, which saves nearly 20,000 acres of land compared with the traditional open channel water conveyance method, and the proportion of land saving is as high as 90%.It will also leave shallow underground space resources for municipal, electricity, gas and other pipe networks and subways, and reserve a large number of surface and shallow underground space resources for the future development of the Bay Area.
In addition, considering the efficient operation and low-energy operation after the completion of the project, the construction team integrated advanced information technologies such as the Internet of Things, big data, and cloud computing into the design work, and built systems such as project management, site supervision, safety monitoring, quality inspection, BIM+GIS, and electronic files, providing all-round perception and multi-dimensional services for engineering construction management, and making every effort to build an ecological and smart water conservancy project in the new era.
Weibo software empowers construction
Pearl River Delta Water Resources Allocation ProjectApply the electronic file management system of Weibo software, comprehensive construction units, operating units management requirements, the establishment of electronic archives management, taking into account the construction project and enterprise archives resource utilization needs. The electronic file management system receives electronic documents formed by multiple business systems, and successfully realizes the single set management of various types of electronic files such as drawings, quality assessment documents, BIM results, and audio and video materials.
In March 2022, the Pearl River Delta Water Resources Allocation Project was identified as:The third batch of pilot projects of electronic document archiving and electronic archives management of the National Archives Administration。In the whole process, Weibo Software supports the Pearl River Delta Water Resources Allocation Project to carry out relevant pilot work and provides technical support.
Guangdong Yuehai Pearl River Delta Water Supply, the construction unit of the Pearl River Delta Water Resources Allocation Project, joined hands with Weibo Software to carry out the construction of digital archives around the construction goal of "building an ecological and intelligent water conservancy project in the new era". According to the construction requirements, combined with the actual work of enterprise archives, and relying on the construction of the water resources allocation project in the Pearl River Delta, Weibo Software promotes the digital, standardized and systematic construction of digital archives and improves the level of enterprise archives management. In 2023, Weibai helped the company successfully pass the evaluation of Guangdong Provincial Enterprise Digital Archives, and used Weibai's electronic file system and technical support services throughout the process.
