Overview of Hydraulic Weir
Hydraulic weir also known as spillway weir, can help prevent flooding and protect downstream areas. The hydraulic structure is also highly durable and reliable, with low maintenance requirements. Hydraulic dam can be designed to meet a wide range of project requirements, making them a versatile solution for water management applications.
Hydraulic cylinders support at the back of the panel to lift up the gate for blocking water or to drop down the gate in the case of flood discharging. Hydraulic structure is applicable to various hydrological and geological conditions; hydraulic barrages are widely used in river landscape, storage of irrigation water, expension of reservoir capacity and other water conservancy hydropower, water ecological civilization and urbanization construction projects. This technology has obtained series of patents issued by State Intellectual Property Office of P.R.C and has been listed in 2014 Catalogue of Key Promotion and Guiding for Advanced Water Conservancy Practical Technologies.
As a professional hydraulic dam construction company, spillway weirs include rubber weir and simplified elevated dam, custom design and service are provided by BIC, according to overseas and national water resources and hydropower environments.
Water Level Control and Flood Protection
Modern dams rely on hydraulic drive systems with cylinders to manage gate movement and positioning for both water level control and flood protection. Depending on the gate type—radial, rotary, slide, or flap—the hydraulic cylinders must be custom-engineered to suit the specific mechanical configuration. These designs can follow DIN, ASME, or regional standards, and can be adapted to meet unique customer requirements. Key functions such as load holding, synchronization, and safety are achieved through manifold blocks, which are typically directly flanged to the cylinders. By offering in-house engineering and production of both hydraulic manifolds and power units, we provide customers with fully integrated system solutions for civil engineering applications. A reference list showcasing our experience from over 300 projects is available upon request.

Applications of hydraulic weirs
Hydraulic weirs are used in a variety of water management applications, including flood control, dam safety, hydroelectric power generation, and navigation. Radial spillway gates can be installed in a variety of hydraulic structures, including spillway weirs and spillway dams. Spillway tainter gates are often used in conjunction with other water management solutions, such as inflatable rubber dams and water diversion structures.
Widens Hydraulic Dam applicability to special conditions, such as mountain area, cities, rivers have floating matters, siltation and ice discharging.
