Successful Practice of the Rubber Dam Project in Zhangzhou City, Fujian Province

Since its completion and commissioning in 2012, the Rubber Dam Project in Zhangzhou City, Fujian Province has not only become a core facility of the local water conservancy system, but also demonstrated the advantages of rubber dam technology in urban water conservancy construction through its diverse benefits.

I. Project Overview: A Core Water Conservancy Facility Adapting to Regional Needs

The rubber dam in Zhangzhou City, Fujian Province, with a height of 2.5 meters and a length of 180 meters, was officially completed in 2012. As a key project for river regulation and water resource control in Zhangzhou City, this rubber dam needs to take on multiple tasks such as flood control, irrigation, and water environment improvement. The technical team of Qingdao Hechang High-Tech Equipment Manufacturing Co., Ltd. participated in the core links of the project throughout the whole process. From the early-stage design to the later-stage construction, they fully integrated the local hydrological characteristics and topographic conditions to ensure that the dam body is highly compatible with the regional water conservancy system.

II. Technology and Craftsmanship: Core Support for Ensuring Project Quality

The rubber dam bag, the core component of the rubber dam, is the key carrier of the project's technology. Our technical team adopts high-strength and anti-aging special rubber materials, endowing the dam bag with excellent water pressure resistance, ultraviolet resistance, and corrosion resistance, enabling it to operate stably in the natural water environment for a long time. During the construction phase, the team precisely controlled the flatness and sealing of the dam bag installation, and optimized the foundation engineering structure according to the local geological characteristics to ensure the overall firmness of the dam body.

In addition, the automated filling and drainage system supporting the project is a major highlight: through intelligent control technology, the height of the dam body can be quickly adjusted according to the river water level and water demand, realizing "impoundment on demand and efficient flood discharge", which greatly improves the convenience and accuracy of operation and management.

III. Operation Effects: A Model Project with Both Water Conservancy and Social Values

Over the past decade since its commissioning, this rubber dam has achieved remarkable results:

• • Flood Control and Disaster Mitigation: During the flood season, the dam height can be quickly lowered to discharge floods, effectively enhancing the river's flood-carrying capacity and building a "safety barrier" for residents and farmland along the coast.
• • Irrigation Empowerment: During the non-flood season, it stores water to provide a stable irrigation water source for tens of thousands of mu of farmland in the surrounding areas, directly contributing to the efficiency improvement of agricultural production.
• • Ecological Benefits for the People: The wide water surface formed by the dam's impoundment has improved the regional water environment and become a new venue for citizens' leisure and sightseeing, featuring both ecological and social benefits.

The success of this project not only verifies the technical strength of Qingdao Hechang's technical team in the field of water conservancy equipment manufacturing, but also provides a reference model for the construction of similar urban water conservancy projects.

From design to construction, and from technological innovation to benefit realization, the Rubber Dam Project in Zhangzhou City, Fujian Province is a vivid practice of Qingdao Hechang High-Tech Equipment Manufacturing Co., Ltd. in implementing the concept of "water conservancy empowering urban development". With scientific technology and exquisite quality, it has injected strong momentum into urban water conservancy construction and sustainable development.
