Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold-resistant horizontal gutter installed on the wall surface of a structure such as a tunnel to guide water leaking from the wall surface of the structure to a drain.

Joints for concrete construction exist on concrete wall surfaces of structures such as tunnels. In addition, groundwater that has permeated the concrete wall surface may freeze and cause cracks. Groundwater may pass through the concrete wall surface through these joints and cracks and leak into the inside of the tunnel or the like as water leakage.

In order to guide such water leakage to the drainage ditches, conventionally, horizontal and vertical gutters have been installed on the walls of structures. An example of a conventional horizontal gutter is described in Patent Document 1. As shown in FIG. 6, the structure is such that a water guide trough 12 having a U-shaped cross section is fixed to a wall surface 10 with an anchor bolt 11 . However, in cold regions, the leaked water freezes inside the water conduit 12, making it difficult to flow, creating icicles and side ice, which poses a danger to people and vehicles passing through the tunnel and may damage electrical equipment. be.

Therefore, Patent Document 1 also describes a cold-resistant horizontal gutter suitable for cold regions. As shown in FIG. 7, the structure is such that the periphery is surrounded by a heat insulating material 13 to block it from the outside air so that it will not freeze even when the outside temperature drops. However, the cold-resistant horizontal gutter covered with the heat insulating material 13 as shown in FIG. 7 has a problem that maintenance and inspection work is difficult because the operator cannot visually confirm the frozen state inside.
