Heat-insulating surface water-conducting panel for preventing tunnel leakage

Abstract

To provide a thermally insulated surface water guide panel for tunnel leakage prevention having a heat insulation property with a thin installation thickness, and securing surface water guide performance as well as preventing leakage of water from a cut-off sheet to a front surface side.SOLUTION: A thermally insulated surface water guide panel 1 includes a panel body 10, for example, three attachment brackets 30, and a pressing plate 5 provided at the lower part on a front side. The panel body 10 comprises a three-layer structure of a front surface panel 11, a thermal insulation layer 12, and a cut-off sheet 13. Each of the three attachment brackets 30 is abutted on a rear surface of a lower rear edge part 114 of a lower panel member 11D, and is fixed on the panel body 10 with a bolt 6 penetrating through the front surface panel 11, the thermal insulation layer 12, the lower rear edge part 114, and the attachment bracket 30, and a nut 7 screwed on a rear end of the bolt 6. Further, a lower part of the cut-off sheet 13 is suspended so as to cover a rear of the fixed attachment bracket 30.SELECTED DRAWING: Figure 3
