| This article deeply analyzes the history of rubber dam, the present home and abroad research and application for it, while predicting its future development.For rubber dam project is of simple structure and easy to operate, while having low requirement for the plate of the foundation, thus the key to rubber dam technology is the dam bag's anti-pull intensity, circum-oriented relative extending rate, internal pressure ratio, anchor structure as well as operation procedure. Citing five-meter-high Nanfei River Rubber Dam in Hefei, one of the highest double-anchor water rubber dam in China as an example, while deeply analyzing some representative rubber dam projects in China, the article theoretically exploits the relationships among some technical parameters such as anti-pull intensity, internal pressure ratio, circum-oriented relative extending rate, etc.Also has the author brought up his own opinion on rubber dam design &calculation theory, which is of high theoretical and applicative value for parameter optimization and combination of water rubber dam with a height of above 3.5 meters. It also helps when building over-five-meter-high rubber dam using seamless rubber dam and rubber dam with steel wire as its frame.This article also exploits safety measures for designing &building rubber dam in navigation areas. It gives some suggestions that should be noticed during the operation management if the rubber dam. It also introduces some simple dam bag repairing technologies. This article is also of some reference value for scientifically running the rubber dam and expanding its life span. |
