Abstract

A cover plate for a dam concrete water-stopping surface is an anti-freezing cover plate for a dam concrete water-stopping surface ice layer expansion joint. The cover plate includes a waterproof seal self-gluing layer; an EPDM layer I is arranged on the waterproof seal self-gluing layer; a reinforcing rib is arranged on the EPDM layer I; an electrical heating layer is arranged on the reinforcing rib; an EPDM layer II is arranged on the electrical heating layer; a waterproof seal gluing layer is arranged on the EPDM layer II; an anti-folding wear-resisting protection film is arranged on the waterproof seal gluing layer; a cable for reflecting the temperature and a water level signal is arranged on the anti-folding wear-resisting protection film; and a waterproof heating layer power supplying cable is arranged under the waterproof seal self-gluing layer. The invention provides an anti-scraping cover plate for dam concrete water-stopping surface ice layer expansion joint and an anti-freezing cover plate for dam concrete water-stopping parts, water gate working door pages, and embedded parts. The cover plate is high in tensile strength, is excellent in anti-collision performance, can prevent scraping and freezing, and is long in service life.

Description

technical field [0001] The invention relates to a cover plate used for the concrete facing water surface of a dam. Background technique [0002] At present, the cover plate used for the expansion joint of the concrete facing the water surface of the dam that is prone to freezing in winter, when the water level drops and the frozen layer falls due to suspension, the cover plate will be subjected to a large downward tearing force. When the ice layer breaks and arches upwards, the cover plate will be subjected to a large upward tearing force, such as a very sharp ice blade formed after the ice is broken, then in the process of falling or arching, the surrounding ice will squeeze it It is easy to scratch the cover plate; in addition, it will expand during the process of water turning into ice, so a very large additional load will be applied to the cover plate, and the cover plate itself will become brittle under the change of temperature, causing the cover plate itself It is ea...
