Improvement of Bolt ClipPlate Anchoring Technology for Water Filling Rubber Dams and Its Application

In combination with the rubber dam project at Xiaobudong on the Yihe River at Linyi City, the major technical problems in bolt clip anchoring of water filling rubber dams are fully analyzed. Through the comparison of different anchoring stress conditions of rubber dams on the upper and lower reaches, some improvement on the embedded length and the diameter of anchor bolts is made. New techniques, such as the one time casting of the anchoring elements, anti corrosion treatment of anchoring elements and anti seepage treatment of the anchorage lines are proposed, which have been used in the construction of engineering projects and generated great economic benefits.
