Dam waterproof insulation structure and manufacturing method

Abstract

The invention discloses a dam waterproof insulation structure and a manufacturing method. The dam waterproof insulation structure comprises a crush resistance structure plate and an insulation layer;the crush resistance structure plate is used for being fixed to the exterior facade or a slope of a dam, the crush resistance structure plate comprises an installing platform, the bottom end of the insulation layer is arranged at the installing platform, the inner side of the insulation layer is stuck to the exterior facade or the slope, and a first waterproof layer is arranged on the outer surface of the insulation layer. The crush resistance structure plate is arranged below the insulation layer, the crush resistance structure plate is fixed to the dam, upward pressure of water to the bottomof the insulation layer is transmitted to the dam, buoyancy of the insulation layer in water is eliminated, the phenomenon that the insulation layer is damaged or disengaged from the base layer of the dam body is avoided, and the insulation effect is ensured. The first waterproof layer is arranged on the outer surface of the insulation layer, the phenomenon that buoyancy is generated when the insulation layer is soaked with water is avoided, and the stability of the insulation layer is further ensured; the surface of the first waterproof layer is coated with an anti-ice pulling coating, so that the phenomenon that the insulation layer is damaged by an ice layer is avoided.

Description

technical field [0001] The invention relates to the technical field of dam waterproof and heat preservation, in particular to a dam waterproof and heat preservation structure and a manufacturing method. Background technique [0002] Water dams (reservoir dams, canal dams, dams in rivers and lakes, offshore dams, and offshore concrete structures, bridge piers, and embankments, etc.) in cold regions and severe cold regions are used to prevent low temperature freezing and waterproofing in winter. Measures to set up light insulation layers (such as polyurethane foam and polystyrene boards) in the water level fluctuation area of ​​the dam body (including the underwater part), because the specific gravity of light insulation boards is lower than that of water, when soaked in water, the long-term Under a relatively large buoyancy, after a period of time, the bonding force of the interface of the base layer of the insulation layer decreases and / or the strength of the insulation laye...

Problems solved by technology

[0002] Water dams (reservoir dams, canal dams, dams in rivers and lakes, offshore dams, and offshore concrete structures, bridge piers, and embankments, etc.) in cold regions and severe cold regions are used to prevent low temperature freezing and waterproofing in winter. Measures to set up light insulation layers (such as polyurethane foam and polystyrene boards) in the water level fluctuation area of ​​the dam body (including the underwater part), because the specific gravity of light insulation boards is lower than that of water, when soaked in water, the long-term Under a relatively large buoyancy, after a period of time, the bonding force of the interface of the base layer of the insulation layer decreases and / or the strength of the insulation layer body decreases, resulting in it being unable to withstand the buoyancy of the water, the light insulation layer will break away from the base layer of the dam body and float to the On the water surface, the thermal insulation failure and waterproof failure caused the dam to lose its protective function; in addition, after the water surface of the low-temperature dam freezes, the ice layer sticks to the thermal insulation material on the surface of the dam. Due to the low body strength of the lightweight thermal insulation layer , when the temperature rises, the water level drops after the ice body away from the dam melts, and the ice lump or thick ice layer adhering to the dam insulation layer or the concrete surface of the dam pulls down the insulation layer or the concrete base layer, causing the insulation layer and / or concrete failure
