Description

  The present invention relates to a side groove cover constituting a side groove installed as a drainage groove, a side groove using the side groove lid, and a construction method thereof.

  A conventional lid-type side groove has a structure in which a handle hole is provided in the lid for the purpose of cleaning the inside of the side groove, and the lid and the side groove main body are separated. For this reason, there is a problem that it is difficult to walk on the side groove, and when the vehicle passes on the side groove, it makes a rattling sound and is troublesome. Conventionally, this problem has been dealt with by integrating the lid and the side groove main body with cast-in-place concrete, but there is a problem that the construction period becomes long because curing is required.

  Therefore, steel permeable lid construction methods (see, for example, Patent Document 1), concrete buried lid construction methods, and the like have been developed as methods that can cope with this. In these methods, the surface of the gutter is asphalt pavement, making it easy for pedestrians to walk and improving visibility for car drivers. However, these methods are not necessarily economically advantageous.
