Description

  The present invention is a collection that can guide a fluid such as rainwater on a road surface into a drainage channel with a side groove lid, a pedestrian boundary block, or the like that is provided so as to cover an opening region of the drainage channel such as a U-shaped groove. The present invention relates to a concrete secondary molded product having a water function, a road structure configured using a large number of concrete secondary molded products having a water collecting function, and a method for molding a concrete secondary molded product having a water collecting function.

For example, a drainage channel such as a side ditch is provided at the end of a roadway or sidewalk to collect and flow rainwater or domestic wastewater. Among such drainage channels, those having an open upper surface are provided with a lid (side groove lid) or the like so as to cover the open area. There is also a type (pedal road boundary block) that also serves as a boundary block that describes the boundary between the roadway and the sidewalk.
These side gutter lids and boundary blocks are provided with water collection holes (also referred to as drainage slits, etc.) for actively collecting rainwater or sewage flowing on the road into the drainage channel. Many are provided.

  Conventionally, the water collecting hole provided to guide such rainwater to the drainage channel is clogged with mud, sand, fallen leaves, etc., and the water collecting ability is reduced or it does not function at all. The problem of not having occurred.

  Therefore, in order to solve such a problem, the prior art is trying to eliminate the clogging of the water collecting hole by forming the water collecting hole into a tapered shape (a hem-spreading shape) that is expanded toward the drainage channel. Is also provided (see Patent Document 1).

However, in the case of such a prior art, a separate problem has arisen. In other words, mud, sand and fallen leaves flow into the drainage channel together with rainwater, etc., and the clogging of the water collecting hole is eliminated, but by repeating these, it accumulates at a considerable height at the bottom of the side groove. Things will accumulate.
If mud, sand, fallen leaves, etc., increase in volume at the bottom of the side groove in this way, the side drainage capacity of the side groove is reduced, and in the worst case, there is a possibility that the situation cannot be drained and flooded.

Therefore, when deposits accumulate in the bottom of the side groove to some extent, the local residents open the side groove lid at a predetermined position and scrape the deposits away.
Or, if the amount of deposits is enormous or the range is too wide for the local residents, a specialized cleaning company that has received a request from the government or local residents Open the gutter lid, place the high-pressure washing hose connected to the special vehicle into the gutter, discharge the high-pressure washing water, let the sediment flow in the direction of the designated soot, and the sediment accumulated in the soot It may become a situation where a large-scale work must be performed to suck up the vacuum.
