FIELD: construction.
SUBSTANCE: invention is a water-protective-decorative umbrella, which can be used to solve the problem of diversion from passenger zones of excess water that has entered through joints of tunnel tubing. Umbrella consists of panels with sides (2) installed on sides along long sides of panels and fasteners. Panels consist of three layers: front sheet, which is an element of architectural decor, rear sheet of aluminium and aluminium cellular filler between them, layer (3) of waterproofing, deposited on rear layer.
EFFECT: reduced complexity and labour intensity of installation and repair work with simultaneous provision of effective suspension of umbrella to bearing lining and protection against water penetration for both inclined and horizontal tunnel; longer service life due to use of corrosion-resistant materials; improving repairability due to the fact that the most loaded part of the umbrella – the waterproofing layer does not require special equipment and machines for application and can be repaired or completely replaced directly at the construction site.
