Description

  The present invention relates to a water passage covering device for a groove that covers an upper portion of a groove such as a drainage groove so that water can flow.

  It is a water-flow covering device that covers the upper part of a groove constructed using groove members such as U-shaped groove blocks so that it can harmonize with the scenery of parks and maintained streets. In addition, it is known that a large number of pebbles can be filled so as to be flowable (see, for example, Patent Document 1). In such a water flow covering device, a water permeable grating in which a lattice portion formed by assembling a large number of main bars and cross bars in a lattice shape is disposed at the bottom of a rectangular enclosure frame at an opening at the top of a groove. A structure in which a large number of pebbles are filled in a flowable manner on the lattice portion in the enclosure frame, and receiving frames that are opposed to each other are provided on the upper portions of both side walls of the groove, and a large number of main bars are provided below the receiving frames. And the water-permeable grating formed by assembling the crossbar in a lattice shape is stored to cover the opening at the top of the groove, and a large number of pebbles can flow in the space between the receiving frames on the upper surface side of this water-permeable grating It is configured to be filled.

In such a configuration, a large number of pebbles are filled on the lattice portion of the water-permeable grating or the lattice-like water-permeable grating so as to be flowable without being bonded to each other by an adhesive or the like. Water can flow into the channel through the gaps between the pebbles, and even if mud etc. enters, it is screened out by the movement of pebbles that can flow, and clogging is unlikely to occur. It can be held well over a long period of time. On the other hand, since the upper part of the ditch road is covered with a large number of pebbles, there is an advantage that there is no unnatural appearance and it is in good harmony with the scenery of parks and maintained streets.
