Abstract

The invention discloses a novel rubber dam body. The novel rubber dam body is provided with a dam base, a pier wall and a rubber dam bag, wherein an anchoring device for anchoring the rubber dam bag comprises an anchoring bolt, a steel cushion plate, a bottom cushion sheet, a steel pressing plate and a compression nut; the anchoring bolt and the steel cushion plate are pre-buried in the dam base; the bottom cushion sheet is arranged on the steel cushion plate; two parallel inner pressing strips are arranged under the bottom cushion sheet; two parallel outer pressing strips are arranged under the steel pressing plate; the distance between the outer pressing strips is more than that between the inner pressing strips; a plurality of dam bag protecting plates are hinged on the dam base corresponding to the upstream of the rubber dam bag; the shape of the dam bag protecting plates is adapted to that of the rubber dam bag which is stretched; a water-isolating layer is arranged at the end part position of the inner cavity of the rubber dam bag; and a water inlet / outlet with small caliber is formed in the lower part of the water-isolating layer. Compared with the prior art, the novel rubber dam body has the advantages that the rubber dam bag is prevented from being loosened and worn, leakage of the rubber dam bag and damage to the rubber dam bag are reduced, the maintenance cost and the management cost of the rubber dam bag are reduced, and the rubber dam is enabled to normally run.

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...
