AI Technical Summary
In existing technologies, it is difficult to effectively insulate and retain moisture in bridge piers under low-temperature conditions, which affects the construction quality.
A heat-insulating and moisture-retaining protective cover for a pier has been designed, including a cover body assembly and a sealing connection mechanism. The cover body assembly is composed of multiple layers of materials, including a blended yarn layer, a moisture-absorbing layer, a heat-insulating layer, a wear-resistant layer, a silver ion antibacterial fabric layer, and a UV-resistant layer. It achieves a sealed covering through a through tube, a bottom rope, and an elastic band assembly, and provides heating by combining a disc-shaped graphene electric heating wire.

Technical Field
[0001] This invention relates to the field of pier maintenance cover technology, and in particular to a heat-insulating and moisture-retaining pier maintenance cover. Background Technology
[0002] Concrete needs curing after pouring to reach its proper strength. In road and bridge construction, if there is a sudden drop in temperature, construction is carried out in winter, or construction is carried out in cold regions at high altitudes or latitudes, the temperature for concrete curing may not be reached, affecting the quality of construction.
[0003] The heating and insulation device for concrete curing in pier construction, disclosed in CN221297617U, comprises a heating and insulation module installed on the steel formwork of the pier. The back of the steel formwork has crisscrossing ribs forming grooves between them. Multiple heating and insulation modules are respectively installed in the grooves of the steel formwork. Each heating and insulation module includes a frame, on which an insulation board is fixed. A heating element is disposed on the inner surface of the insulation board. The ribs have through holes, and the outer edge of the frame has a fixing structure that is detachably connected to the through holes. Multiple fixing structures are arranged around the frame.
