Pillow rubber dams are shaped like pillows, and are mainly suitable for low-head, large-span sluices and dams. For example, they are used as gates or movable overflow weirs on reservoir spillways to increase reservoir capacity and power generation heads; they are used as low water heads on rivers. Water heads, large-span rolling dams or overflow weirs can be used without conventional gate hoists, working bridges, etc.; used in canal systems as intake gates, diversion gates, and control gates, which can easily store water and adjust water level and flow ; Used as a wave breakwater or tidal lock along the coast. Because it is not affected by seawater erosion and marine organisms, it has a better effect than metal gates; used for the upstream and downstream gates of ship locks with larger spans; Construction of cofferdams or movable cofferdams, the height of rubber movable cofferdams can be raised and lowered, and can overflow from the top of the weir. It does not need to take soil to build the weir, which can keep the river clean, save labor and shorten the construction period; used in urban garden projects, adopted The colorful dam bags, with beautiful shapes and smooth lines, can add a beautiful scenery to urban construction.
Pillow-type rubber dams are mainly suitable for large-span river projects, used as low-head, large-span dams or overflow weirs on the river, which can easily store water and adjust the water level and flow; used for wave breakers or barriers along the coast Tide gates, because they are not affected by seawater erosion and marine organisms,
During the overflow operation of the rubber dam surface, the dam bag will vibrate, tremble, and vibrate; the main cause of the dam bag vibration when the dam bag collapses and overflows or the negative pressure is generated by flood discharge. The spoiler set on the dam bag body will form an empty space between the dam bag and the spoiler when the water flows over the spoiler.
