Abstract

The invention relates to the technical field of dam body heat preservation layer ice shifting resistance, and particularly relates to a graphene anti-ice-shifting intelligent temperature control structure. The graphene anti-ice-shifting intelligent temperature control structure comprises a polyurethane heat preservation layer, a graphene heating structure system layer, a leveling layer and a one-cloth two-coating polyurea layer which are sequentially arranged on the base face of a dam body in a stacked mode; and the graphene heating structure system layer is connected with a temperature control device. According to the structure, the ice shifting effect is eliminated through the arrangement of the graphene heating structure system layer, and crack harm caused by out-of-control dam heat preservation is avoided.

Description

technical field [0001] The invention relates to the technical field of anti-icing technology of a dam body insulation layer, in particular to a graphene anti-icing intelligent temperature control structure. Background technique [0002] Mass concrete has been widely used in construction projects, especially in water conservancy projects in water conservancy projects. In addition to the construction process of mass concrete projects, it is necessary to overcome the problem of temperature gradient caused by water heating in the initial stage of concrete pouring, and must also overcome the problem of large temperature gradient caused by concrete being a poor conductor under the environmental conditions of large temperature difference in the later stage. , so as to avoid cracks in the concrete and cause greater harm to the dam body. [0003] At present, various types of insulation boards and polyurethane insulation are generally used in the later stage of temperature control. T...

Problems solved by technology

[0003] At present, various types of insulation boards and polyurethane insulation are generally used in the later stage of temperature control. The polyurethane spraying seamless insulation layer with better effect is better, but there are also various factors that cause the base layer of the dam body and the insulation layer to fall off continuously. The reasons are as follows: 1. The thermal insulation is affected by the water pressure, and it is in a state of creep deformation for a long time. The thermal insulation layer completely relies on the bond strength with the dam body to bear the tensile force. Therefore, the firmness between the thermal insulation layer and the dam body is affected by 2. Due to the location of the ground in the alpine region, freezing of the water surface in winter is inevitable, and the bonding between the ice body and the dam body will also change with the water level. The rise and fall of the ice body will generate the pulling force of the ice body on the insulation layer, that is, the phenomenon of ice pulling, which will cause serious damage to the insulation layer and cause the insulation layer to fall off.
