Core Viewpoint - The rapid development of water conservancy construction in recent years has led to the implementation of several major water conservancy projects, particularly those that have been under discussion for many years [1][5]. Group 1: Major Projects and Investments - The "Yin Da Ji Min" project in Sichuan is set to commence construction within the year, with a total static investment of 57.4 billion yuan and a construction period of 96 months [2][3]. - The project aims to draw water from the Dadu River to the Chengdu Plain, with a designed water intake flow of 80 cubic meters per second and a total water conveyance length of 304.4 kilometers [3]. - The project will involve three energy recovery power stations with a total installed capacity of 388 megawatts [3]. Group 2: Water Supply and Coverage - The "Yin Da Ji Min" project will supply water to eight cities and 43 counties, with average water supply volumes projected to be 1.326 billion cubic meters in 2035 and 1.523 billion cubic meters in 2050 [4]. - The Dujiangyan irrigation area is expected to reach an irrigation area of 11.647 million acres by 2025, expanding its coverage to include new regions [4]. Group 3: Growth in Water Investment - National water conservancy investment has shown rapid growth, with significant projects being launched, including the "Yin Da Ji Min" project and others like the "Yin Jiang Bu Han" project, which has a total investment of 58.235 billion yuan [5][6]. - In the first quarter of this year, eight major water conservancy projects were initiated, with a total investment scale of 43.73 billion yuan, representing a year-on-year increase of 27.8% [6]. - Water conservancy construction investment reached a historical high of 1.1996 trillion yuan in 2023, following a record of 1.0893 trillion yuan in 2022, marking a 43.8% increase from 2021 [7].

Core Insights - The Guangxi Water Resource Allocation Project has achieved significant milestones with the early completion of the Mutoulu Tunnel, which was finished 72 days ahead of schedule, and the successful connection of the Chicken Spirit Tunnel's first branch tunnel to the main tunnel [1][2] Group 1: Project Achievements - The Mutoulu Tunnel, measuring 811.24 meters, faced challenges due to poor surrounding rock conditions but was completed ahead of the original contract period [1] - The Chicken Spirit Tunnel's first branch tunnel, approximately 735 meters long, successfully connected to the main tunnel after six months of continuous work [2] Group 2: Construction Techniques and Safety Measures - The construction team implemented strict safety measures and adhered to principles such as "advanced management, strict grouting, short advance, strong support, early closure, and frequent measurement" to ensure safety during the Mutoulu Tunnel's construction [1] - Advanced geological forecasting methods, including TSP and geological radar, were employed to monitor and adjust construction processes dynamically, reducing risks [1][2] Group 3: Project Significance - The Guangxi project is a key national water network initiative, progressing at a rate of 126 meters per day, and aims to create a 491-kilometer "underground galaxy" beneath karst terrain [2]

Group 1 - The approval of construction land for the Guangxi Water Resource Allocation Project (Beihai Section) marks the completion of land approval for all five cities involved, with a total area of 2006 acres [1] - The project is part of the 150 major water conservancy projects deployed by the State Council, with a total investment of 27.839 billion yuan, and is a key component of the national water network [1] - The project will provide urban and industrial water supply for key cities such as Nanning, Beihai, Qinzhou, and Yulin, benefiting nearly 14 million people and supporting agricultural irrigation and ecological improvement [1] Group 2 - Since the construction mobilization meeting on September 8, 2023, all six main lines and twelve branch lines of the Guangxi Water Resource Allocation Project have commenced construction [2] - Key construction milestones include the completion of the first round of preliminary model testing for the main water pump model and the installation of TBM for the Zhoucun tunnel [2]
