Traditional rubber dam anchoring methods have long been beset by various challenges. The soft connections or hinge joints they employ suffer from issues such as insufficient strength, short service life, and weak erosion resistance in river channels, which severely impact the stability and durability of water conservancy projects. The new rubber dam anchoring structure developed by Qingdao Hechang High-tech Equipment Manufacturing Co., Ltd. specifically addresses these industry pain points. Through innovative design, it has achieved multiple breakthroughs in anchoring strength, service life, and installation efficiency, bringing about a revolutionary upgrade to the application of rubber dams in the field of water conservancy engineering. As a key piece of equipment in water conservancy projects for regulating water flow, flood control, and irrigation, the anchoring performance of rubber dams directly determines the safety and durability of the projects. Traditional anchoring methods mostly utilize a single type of soft connection or hinge joint, which generally have problems like insufficient strength, easy leakage, and short service life. Particularly in complex hydrological environments, frequent maintenance not only increases costs but also creates potential safety risks. The new anchoring structure developed by Qingdao Hechang High-tech Equipment innovatively combines bolt anchors with wedge anchors to form a dual protection system. Among them, the bolt anchor features a design of foundation bolts and double nuts. One end is deeply embedded in the foundation to form a stable stress point, and the other end achieves precise fastening through nut adjustment, ensuring the rigid connection strength between the rubber dam and the foundation. The wedge anchor consists of a lower base plate and an upper pressure plate. It tightly clamps the rubber dam body through a wavy contact surface, which not only increases friction to prevent slippage but also forms a multiple sealing structure, effectively solving the leakage problem. The core advantages of this structure are reflected in three aspects: first, the dual anchoring design achieves a "combination of rigidity and flexibility". The bolts provide lasting tensile force, and the wedges disperse local stress, greatly enhancing the overall resistance to water impact; second, the base plates and pressure plates made of special materials reduce wear on the rubber dam body, and together with the anti-corrosion treated bolt components, significantly extend the service life of the equipment; third, the modular installation process greatly simplifies the construction steps, saving a great deal of working hours compared with traditional techniques and reducing labor costs.

In terms of sealing performance, the new structure forms a three-dimensional sealing cavity through the tight interlocking of wedge blocks and the reflexed design of the rubber dam body, significantly reducing the leakage rate. It is particularly suitable for engineering scenarios with high water levels and strong water pressure. Meanwhile, the tightness of the nuts can be adjusted to adapt to different stress environments, offering far greater flexibility than traditional fixed modes.
As an enterprise focusing on innovation in water conservancy equipment, Qingdao Hechang High-tech Equipment Manufacturing Co., Ltd. has obtained a national utility model patent for this newly developed anchoring structure. The promotion and application of this technology will not only improve the safety level of water conservancy projects but also promote the wide application of rubber dams in fields such as urban flood control and ecological landscape, providing solid technical support for water-saving irrigation and water resource management.
Industry experts stated that this new anchoring structure has broken through the bottlenecks of traditional technologies. Its characteristics of "high strength + long service life + easy installation" are expected to become the new industry standard for rubber dam anchoring, helping China's water conservancy project construction move towards efficiency, safety, and low carbon.
The general manager of Qingdao Hechang High-tech Equipment Manufacturing Co., Ltd. said that the next step will be to develop a series of anchoring products based on this patented technology and collaborate with scientific research institutions to carry out research on the application of long-span rubber dams. "We hope that through technological innovation, rubber dams, as green water conservancy facilities, can play a role in more regions and provide equipment support for national strategies such as water-saving irrigation and ecological restoration."
