Description

  The present invention relates to a lid receiving structure for a grating lid installed in the middle of a water permeable side groove in a water permeable side groove whose upper surface of a side groove main body is covered with a water permeable road surface layer having a rainwater drainage function.

Conventionally, a water-permeable side groove is known in which the upper surface of the side groove body is covered with a water-permeable road surface layer having a rainwater drainage function (see Patent Document 1 and Patent Document 2).
This water-permeable side groove forms a lid by connecting a plurality of lid members made of chevron-shaped molds while maintaining gaps that serve as water openings, and this lid is formed between the left and right lid receiving step surfaces formed on the side groove body. This is a culvert structure in which a water-permeable road surface layer is formed on the lid.
Therefore, rainwater permeates through the water-permeable road surface layer and flows into the inside of the side groove main body through the gap between the lid members forming the lid, thereby allowing rainwater to be efficiently drained into the side groove.

In such a water-permeable side groove, a grating lid is installed in the middle.
In the lid receiving structure of the grating lid, a lid receiving frame is placed between the left and right lid receiving step surfaces formed on the side groove main body, and the lid receiving frame is placed on the left and right lid receiving step surfaces. The vertical frame member and the front and rear horizontal frame members connected and fixed between both ends of the vertical frame member are formed into a rectangular frame, and the front and rear support frame members that support the grating lid from below are formed in the lid receiving frame. Provided (see Patent Document 3).
The grating lid has a function as a water drop lid, and when this grating lid is removed, it becomes an opening of a water-permeable side groove (underdrain), so cleaning and inspection of the underdrain is performed through this opening. It also has a function as a management bag that can be used.

When cleaning the inside of a water-permeable side groove, it is common to use high-pressure washing and vacuum together. Insert the washing hose and vacuum hose into the underdrain with the grating lid removed. .
However, in the conventional grating lid cover receiving structure, the front and rear support frame members that support the grating lid from below are connected and fixed along the inner surfaces of the front and rear horizontal frame members that constitute the lid receiving frame. The opening length in the front-rear direction is shortened by the presence of the support frame member.
For this reason, when inserting the hose for washing | cleaning and the hose for vacuums into a culvert from an opening part, there existed a problem that an operation | work became difficult.

  In addition, conventionally, since the front and rear support frame members that support the grating lid from below are attached in contact with the inner surfaces of the front and rear horizontal frame members constituting the lid receiving frame, at the front and rear ends of the grating lid, There is no place for earth and sand to flow down from the grating lid, and earth and sand stays in the corners between the inner surfaces of the front and rear horizontal frame members and the upper surface of the front and rear support frame members, causing clogging and impairing the water drop function. There was a problem.
