三乡水浸追踪：大涌口泵站2028年完工，有望缓解内涝积水

Core Viewpoint - The article discusses the severe flooding issues faced by Sanxiang Town in Zhongshan during heavy rainfall, highlighting the ongoing construction of the Maowan River flood control project aimed at alleviating these problems by 2028 [1][4][6]. Group 1: Flooding Issues in Sanxiang - Sanxiang Town has historically suffered from severe flooding due to its geographical location, which resembles a "water basin" with limited drainage channels [3][4]. - The recent heavy rainfall recorded a maximum of 214 mm in three hours, classified as a once-in-a-century event, exacerbating the flooding situation [1][3]. - The town's drainage relies heavily on the Maowan River, which has limited capacity to handle the influx of water during heavy rains [3][4]. Group 2: Flood Control Measures - The Maowan River flood control project, initiated in early 2022, consists of four phases and aims to create a comprehensive flood defense system [4][6]. - The project has already shown effectiveness, with approximately 600,000 cubic meters of water volume reduced during the recent flooding due to the construction of various flood control facilities [5][6]. - The first phase of the project, which includes the expansion of drainage channels, is nearly complete, while the second phase has also made significant progress [4][5]. Group 3: Future Improvements - The total investment for the Maowan River flood control project is 4.062 billion yuan, with the completion expected by 2028 [6][10]. - The construction of the Dayongkou Pump Station is crucial for enhancing drainage capacity and is anticipated to fundamentally resolve the flooding issues caused by external tidal influences [10][12]. - The project aims to significantly improve the annual flooding conditions in Sanxiang and surrounding areas once fully operational [6][10]. Group 4: Emergency Response and Preparedness - Sanxiang Town has implemented effective emergency response measures, achieving zero casualties during the recent flooding event [13][15]. - The town's proactive approach included preemptive drainage of newly constructed flood control lakes and coordinated emergency response efforts [13][15]. - Compared to previous years, the number of affected underground parking lots and damaged vehicles has significantly decreased, indicating improved flood management [15].
