Description

  The present invention relates to a structure of a groove lid receiving frame portion of a water channel block and a groove lid receiving frame member of the water channel block.

  Conventionally, a water channel block provided as a side groove for drainage on a sidewalk or a roadway is widely known, and the water channel block has a water channel groove inside a concrete block body having a U-shaped or inverted U-shaped cross section. An opening is formed on the upper surface of the block body so that the groove lid can be removably mounted. For example, rainwater that accumulates on the road surface during rainfall is collected at the road edge by the slope provided on the road, and is collected and drained from the groove lid provided on the upper surface of the side groove to the waterway groove inside the waterway block. .

  However, it is rainwater that flows in from the upper side that drains from the conventional groove lid. There was a problem that rainwater collected at the stepped portion formed between the pavement layer and the side wall of the side groove on which the groove cover was placed, and the road could not be drained sufficiently from the groove cover and the road was flooded, resulting in obstacles to traffic. Further, in recent years, a water-permeable pavement layer having good drainage is provided on the surface layer portion to prevent flooding of the road pavement surface. Even in this case, it is necessary to collect and drain rainwater that accumulates between the permeable pavement layer and the non-permeable pavement layer below it. Has also been proposed (see, for example, Patent Document 1).

  In the drainage block as a drainage facility for this drainable pavement, the groove lid is formed of reinforced concrete, and a belt-like slit portion is formed in the longitudinal direction at the center portion of the groove lid, and is fitted into the slit portion. Grating is provided. Also, a drain hole is formed in the side surface of the groove lid, and a resin drain pipe communicating from the drain hole to the inside of the groove is embedded, and water is collected around the drain hole in the side surface for collecting water. A recess is formed. By comprising in this way, rain water can be drained from the groove lid side surface to the groove inside the channel block.

However, when an impact or load is applied due to the passage of a person or vehicle on the upper surface of the groove lid, if a resin drain pipe is buried inside the concrete groove lid as described above, the groove will depend on the usage environment. There is a risk of damage due to insufficient strength of the lid. In addition, there is a concern that sufficient drainage capacity cannot be obtained when regulating the number of drain pipes and the size of the diameter in order to prevent a decrease in strength. Furthermore, at the time of forming the groove lid, it is necessary to fix a resin drain pipe in the mold or to form a notch that becomes a water intake recess, which makes the manufacturing process extremely complicated.
