Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a combined rubber dam structure. Background Art

[0002] Rubber dam, also known as rubber sluice, is made of high-strength synthetic fiber fabric as a load-bearing frame, coated with rubber inside and outside as a protective layer, processed into rubber tape, and then anchored to the dam bag on the reinforced concrete fixed dam body. However, the existing rubber dam structure has the following disadvantages:

[0003] At present, the injection and drainage pipe of the rubber dam is fixedly connected to the dam bag. When the dam bag is filled with water and swells, the connection between the injection and drainage pipe and the dam bag will be stretched open. The frequent filling and drainage of the dam bag will affect the sealing of the connection between the injection and drainage pipe and the dam bag. Secondly, the dam bag is easily scratched by sharp objects in the water during use, thereby affecting the service life of the rubber dam. Therefore, the utility model proposes a combined rubber dam structure. Utility Model Content
