Abstract

The invention discloses a novel rubber dam body, which comprises a dam base located on the bottom part of a riverbed and constructed by concrete, rubber cloth and pier walls arranged on the dam base at intervals. A plurality of bolts are pre-buried on two sides of the pier walls and the dam base; the rubber cloth is fixed onto the dam base and the pier walls through a sealing and pressing mechanism; and the sealing and pressing mechanism comprises rubber gaskets sleeving on the bolts, pressing pillars pressing on the rubber cloth and sleeving on the bolts, and screw caps in threaded connectionwith the bolts. The novel rubber dam body provided by the invention is easy to press the bolts, uniform in stress distribution, good in sealing effect, not easy to damage a dam bag, and particularlysuitable for a dam height exceeding more than 7m.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering construction, and in particular relates to a novel rubber dam body. Background technique [0002] The rubber dam project is a new type of water-retaining structure, which uses rubber and fiber-synthesized adhesive cloth as the dam bag, which is anchored on the dam floor to form a closed flexible water-retaining structure. Because of its novel structure, convenient lifting, obvious social benefits, and convenient management, it is widely used in many fields such as flood control, irrigation, urban and rural water supply, hydropower generation, and beautification of the environment. The rubber dam bag is filled with water and stretched, and the dam bag bears the internal and external pressure of the water. It is the main body of the water retaining operation of the project. The anchorage of the rubber dam bag must not only have good sealing performance, but also be firm and rel...
