Comparison of Advantages Between Pneumatic Shield Gates and Rubber Dams in Shenyang – Let’s Take a Look!
We hope this brief overview can offer useful references for you.
A rubber dam is constructed by anchoring high-molecular synthetic materials onto a base slab to form an enclosed structure. It inflates with water or air to serve as a water-retaining barrier. When water retention is no longer needed, the water or air inside the dam bladder is drained, restoring the original flow cross-section of rivers and canals. Rubber dams are widely applied in flood control, irrigation, power generation, water supply, inland waterway navigation, tide retention, urban landscape improvement, as well as movable cofferdams and temporary water-blocking works for canal systems.
Compared with conventional sluice dams, rubber dams feature the following merits:
Reduced consumption of three key construction materials: steel, timber and cement;
Lower construction cost, cutting total investment by 30% to 70% in most cases;
Simple structure and short construction cycle, normally ranging from 3 to 6 months;
Large single-span layout, negligible flow obstruction, light dead weight and excellent seismic resistance.
Rubber dams are mainly applicable to sluice and dam projects with low water head and large span. They can be installed on reservoir spillways as gates or movable overflow weirs to expand reservoir storage capacity and power generation head. Built across river courses as low-head long-span overflow dams or weirs, they eliminate the need for hoisting equipment and service bridges required for conventional sluices. Deployed in canal systems as intake gates, diversion gates and check gates, they facilitate convenient water storage as well as water level and flow regulation.
Shenyang pneumatic shield gates are adopted for coastal wave breakwaters and tide gates. Resistant to seawater corrosion and marine organism attachment, they outperform metal sluice gates in service performance. They also work as upstream and downstream gates for large-span lock bays of ship locks. When used as construction or movable cofferdams, rubber movable cofferdams feature adjustable elevation and allow overflow over the weir crest. Earth filling for cofferdam construction is unnecessary, keeping river channels clean while cutting labor costs and construction periods. For urban landscape projects, rubber dams with colored bladders boast elegant shapes and smooth lines, serving as attractive urban landmarks.
Welcome to our company for consultation on purchasing Shenyang pneumatic shield gates. We will elaborate further in our next session. Goodbye!
