@, Good news!Another people's livelihood project starts

The mountains and rivers and the livelihood, Sanjiang connected to promote development

September 29th

Hanjiang Rongjiang Lianjiang Water Department Connection

The follow -up optimization project officially started construction

This project is a major people's livelihood water conservancy project that the Guangdong Provincial Party Committee and the Provincial Government have highly planned construction from a global situation. Sexual water deficiency problems, supporting high -quality development of East Guangdong region, and accelerating the construction of the "one core, one area, one area" regional development pattern are of great significance.

Covering more than 8.5 million people in eastern Guangdong

"After the project is completed, more than 800,000 people in eastern Guangdong increased an average of 311 million cubic meters per year. It will effectively increase the water supply and emergency water supply capacity of eastern Guangdong, forming a water supply, complementary, and sustainable water supply. The guarantee system. "Zhu Chaorong, director of the Construction Division of the Provincial Water Resources Department.

The Hanjiang River Basin is wide, the Rongjiang River is deeply beautiful, and the trainer is roundabout. However, due to the uneven distribution of local water resources, the local storage capacity is insufficient, and the contradictions of water are prominent. In recent years, with the development of economic and social development, the lack of water allocation capabilities has become a major bottleneck that restricts the development of eastern Guangdong. Especially in 2020 and 2021, the Hanjiang River Basin and eastern Guangdong have encountered rare drought in history, and the resources and engineering water deficiency in the eastern Guangdong region were further prominent.

In this regard, the Guangdong Provincial Party Committee and the Provincial Government attach great importance to the overall planning of the economic and social development of the eastern Guangdong region to build water conservancy projects and revitalize water resources in eastern Guangdong.

Last year, the Luhu Tunnel Dreatment Project of Luhu Tunnel was built in Luhu Tunnel Dreatment Project (hereinafter referred to as the "Sanjiang" connection project) of the Hanjiang Rongjiang Lianjiang Water Department (hereinafter referred to as the "Sanjiang" connection project). The tensions of long -term water sources, insufficient water supply, and water quality deficiency in the Jieyang area are greatly alleviated.

In order to better optimize the regional water resource allocation pattern and improve the regional water safety guarantee capacity, the follow -up optimization project of the "Sanjiang" connection project will be based on the "Sanjiang" connection project to use the basically built Luhu Tunnel water drainage project and Rongjiang Guanbu water drainage project, newly built a closed water pipeline, and deployed Hanjiang water resources to Shantou Chaoyang District, Chaonan District and Jieyang Puning City, and Chao'an District, Chaozhou City. The original ecological hydration function designed by the "Sanjiang" connection project will be adjusted to focus on urban and rural water supply, and taking into account the improvement of the water ecological environment.

According to reports, the project is composed of "one -to -two branches". The project will receive water from Xishan Creek, the end of Chao'an Ancient Lane from the end of the Hanjiang Luhu Tunnel Tuning Project, build a pipe in the pipeline of the main drums, pasto the water of the Hanjiang River to the Rongjiang Guanbu to pick up the water inlet, and then use the Rongjiang Guanbu to divert water project. Through Chaoyang split trunk lines, Puning, and Chaonan split lines, they are watering to the Hexi Reservoir of Chaoyang District, the Tangkeng Reservoir of Puning City, and the Qiufeng Reservoir in Chaonan District. At the same time, Puning and Chaonan Branch Create 1 new mountain pumping station, with a total installed capacity of 7,200 kilowatts.

The project is expected to be completed in 2026

The follow -up optimization project of Hanjiang Rongjiang Lianjiang Water Department is responsible for investing, construction, and operation management by Yuehai Group. The total investment of the project is 10.118 billion yuan, the total length of the water traffic line is 71.65 kilometers, and the total construction period is 40 months. It is expected to be completed in 2026.

"About half of the water recowing lines of more than 70 kilometers are shield construction. The construction of mountains, rivers, and railways requires many times along the construction line. The construction is extremely difficult." Said Liu Meisheng, general manager of Guangdong Yuehai Yue Water Supply Co., Ltd.

According to Zhang Wu, the person in charge of the project project, the water level height difference of 10 meters to 20 meters in the water level of Hanjiang and Rongjiang systems. During the construction of the project, the water flow is smoothly connected and the pressure is accurately regulated. At the same time, the project needs to overcome complex water conditions and hydrogeological conditions.

For example, the shield tunnel of about 20 kilometers in length is located in the fourth -series accumulation layer mainly based on sludge, sludge soil, viscous soil, and sand layer. The shield water tunnel tunnel is facing severe softness and sand layer liquefaction. The project of the project Chaoyang Division of Yanbird Mountain to Dadan Mountain needs to cross the mountain with a length of about 2.5 kilometers. It is mainly located in the weak and weathered granite belt to the breeze belt, and the rock quality is hard. In addition, the Chaoyang split trunk line TBM tunnel is about 3.9 kilometers long, with an buried depth of more than 200 meters, and there are no less than 11 broken layers of broken belt. The construction difficulty is extremely high.

In the next 40 months, the construction team will rely on scientific and technological innovation, apply new processes and methods, and gradually overcome the design of the deep -rich and weak strata shield tunnel design and the stable and infiltration control technology, Hanjiang Rongjiang training in the river system Key technologies of connecting pressure control flow and optimization scheduling of multi -water sources, under the conditions of hard rock geological conditions, no well -receiving rock top pipes in the top of key technologies, large buried and deep -fractured super -hard rocks and other complex geological conditions, TBM key construction technology, etc. Difficulty in items.

The relevant person in charge of the Provincial Department of Water Conservancy said that with the construction of a series of people's livelihood water conservancy projects in the future, the problem of tight urban and rural life water in the eastern area of ​​Guangdong will be fundamentally solved. Provide solid water conservancy support for the high -quality development of eastern Guangdong.
