Rubber dam, also called rubber sluices, are made from high strength synthetic fiber fabric mechanical skeleton, internal and external coating rubber protective layer, processed into fabric, then its anchorage in the floor into a closed dam bag, through the pipe ing water (gas) will be the bulge forming filling bag over the dam.The dam crest can overflow, and can adjust the dam height according to the need, control the upstream water level to play the benefit of irrigation, power generation, shipping, flood control and tide.Rubber dam is also called rubber sluice, which can be divided into two types: water filling and inflatable.
feature
Rubber DAMS are divided into two types: water filling and inflatable.The filling time of the dam is longer than the inflatable dam.In terms of cost, the two types of DAMS are similar.The application condition of rubber dam is similar to the sluice gate, and it has the following characteristics compared with the conventional dam.
One is low cost.Can reduce investment 30% ~ 70%, can save steel 30% ~ 50%, cement 50%, lumber 60% above.
Second, the construction period is short.The dam can be installed only 3 days to 15 days. Most of the rubber dam construction benefits in that year.
The three is the soft shell structure of the dam, which can resist earthquakes, waves and other shocks, and the water stop is good, the span is large, and the flood season is not blocked, which can be used for landscaping in urban areas.
Fourth, the maintenance is small, the management is convenient.The life of rubber dam bags is usually 15 ~ 25 years.
Construction: rubber dam is mainly composed of civil parts, dam bags and anchoring parts, filling and drainage (gas) facilities and control system.The rubber dam should be carried out in strict accordance with the prescribed scheme and operating procedures. The pressure of water filling in the dam should not exceed the design pressure, so as to avoid the blasting of the dam bag.Rubber dam, although few repairs, unlike conventional steel gate, which needs regular besmear brushs antirust paint, but also should check regularly, especially after the flood, to check whether there is a floater stabbed on the dam bag, as well as the dam, dam vibration friction wear, pebble hit the bag and the bottom the impact of the dam bag, etc.Rubber dam bags can be easily damaged by sharp and tau kok objects. Therefore, the management scope and safety area of rubber dam should be de
apply
Rubber dam to increase reservoir capacity and power generation head;Used for water rolling dam or overflow weir, which can be used as low water head, large span, etc.It can be used as the entrance lock, water sluice and control gate to conveniently store and regulate water level and flow.Used for seawall or dam breakers along the coast, which is better than the metal gate due to the impact of sea water and Marine life.For the upper and lower gate of the gate lock with larger span;For construction cofferdam or activity weir, rubber activity cofferdam height can be raised and can be lowered, and can be overflowed from the weir, not to be used to build weir can keep the channel clean, save labor and shorten the working period;Used for urban landscaping works, with color dam bags, beautiful shape, smooth n add a beautiful scenery for urban construction.
