Integrated water filled rubber dam: It is a rubber dam bag made by molding the dam fabric skeleton material and inner and outer covering rubber according to the entire process, and through continuous one-time vulcanization process. The overall water filled rubber dam uses water as the expansion medium and is divided into two types: slope type and plug type.
Product principle
Using the hollow principle, when inflating or filling with water, the rubber expands, the dam body increases, the water is accumulated, and the water level is raised; When flood discharge is required, water or air should be discharged, and the height of the dam body should be lowered. The rubber dam material is composed of reinforced canvas that bears the tension of the dam bag and a rubber layer that protects the canvas and ensures airtightness. The rubber layer is usually distributed in the outer, middle, and inner layers of the dam bag, exerting the effectiveness of each layer of rubber。
| Outer rubber Due to the high amount of floating debris in rivers, special rubber with properties such as wear resistance, sunlight resistance, heat resistance, and ozone resistance is used. | Middle layer rubber Directly protecting the rubber layer of the canvas, connecting two or more layers of canvas, providing good adhesion between the rubber and canvas. | Inner layer rubber In addition to its function of protecting canvas, it also has high water and air tightness. |
| The difference from traditional splicing rubber dams in China is that the overall dam bag does not have a repeated process of secondary vulcanization and secondary splicing. The fabric strength of the dam bag in the warp and weft directions is consistent, and the thickness is uniform. There are no relatively weak links in the overlapping parts of the entire dam body. ● Time saving:The overall dam bag technology has high production efficiency and short delivery time. ● Material saving:There is no need to use materials such as leveling plates during installation. ● Save money:The manufacturing cost of integrated dam bag technology is reduced, with high cost-effectiveness and comprehensive benefits. |
The operating conditions of rubber dams are similar to those of water gates, and compared with conventional gate dams, they have the following characteristics:
| Low cost It can reduce investment by 30% to 70%, save steel by 30% to 50%, cement by about 50%, and wood by more than 60%. | Short construction period The installation of the dam bag can be completed in only 3-15 days, and most rubber dam projects benefit from the same year of construction. |
| Flexible soft shell structure The dam body is a flexible soft shell structure that can resist earthquakes, waves and other impacts, and has good water stopping effect. It has a large span and does not block water during the flood season. It can be used for urban landscaping. | Less maintenance, convenient management The service life of rubber dam bags is generally 15-25 years. |
Rubber dams are mainly suitable for low head, large-span gate and dam engineering, such as serving as gates or movable overflow weirs on reservoir spillway to increase reservoir capacity and power generation head; Used as a low head, large-span rolling dam or overflow weir on rivers, without the need for conventional gate hoists, working bridges, etc; Used as an inlet gate, diversion gate, and regulating gate on the canal system, it can conveniently store water and regulate water level and flow rate; Used as a breakwater or tidal gate along the coast, it is more effective than metal gates as it is not affected by seawater erosion and marine life; Used for upstream and downstream gates of large-span orifice locks; Used for construction or activity cofferdams, rubber activity cofferdams can be raised or lowered in height, and can overflow from the top of the cofferdam. It does not require soil to build a cofferdam, which can keep the river clean, save labor, and shorten the construction period; Used for urban landscaping projects, it adopts colored dam bags with beautiful shapes and smooth lines, which can add a beautiful scenery to urban construction.
Hydroelectric power generation Rubber dams can increase the capacity of reservoirs, increase the water flow drop of reservoirs, and thus increase power generation. | Recharge groundwater Rubber dams can throttle the river channel at the mouth of the sea, increase the upstream water level, and increase the amount of groundwater recharge. | Rainwater and sewage diversion Rubber dams can divert rivers, thereby maintaining the ecology of water sources and avoiding water pollution. | To block saltiness and store light Rubber dams can be built at the estuary to protect the freshwater resources of rivers. | Urban landscape Rubber dams can raise the upstream water level, form a large area of gentle water surface, and enrich the urban landscape. |
