Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container lid used for a container such as a side groove and a drainage groove.

[0002]

2. Description of the Related Art In gutters of roads and the like, stiles are installed at locations where the direction of the gutters is changed in the course of the ditch and the road merges or branches with other gutters. The basin is formed deeper than the gutter, and water from the upstream side of the gutter flows into the basin and then flows out into the gutter on the downstream side.

The structure of the basin differs depending on its installation location and the structure of the gutter. For example, a basin installed in a gutter below the slope of a road has an internal dimension of 300 as shown in FIG.
A concrete sill body 50 having a depth of about 500 mm to a depth of about 500 to 1000 mm and a cover 60 is used.

The container main body 50 is formed by stacking a plurality of stages of cylindrical blocks 52 and 53 on a bottom plate 51. On the uppermost block 53, a grid-shaped cast steel or concrete lid called grating is used. 60 is mounted.

[0005]

Since the lid 60 has holes formed at lattice intervals of about several mm so that water from the road surface or the slope can easily flow into the main body 50 of the grid,
Various substances such as earth and sand, dust, and dead branches flow into the basin body 50 together with water through the holes. Most of the substance that has flowed into the container main body 50 flows out to the gutter on the downstream side together with water, but a part thereof is deposited on the bottom of the container main body 50.

[0006] When dust or the like is accumulated in the main body 50, not only the water flow into and out of the gutter becomes worse, but also the water overflows from the grid to the road, and the lid 60 is pushed up together with the deposits and comes off. . For this reason, the deposit has to be removed, and the work of removing this deposit is conventionally done in a few months.
It is done at a rate of about once.

This work of removing the deposits must be carried out manually in a narrow pit, and since the number of pits is extremely large, a great deal of labor is required for the work. This kind of problem is not limited to the gravel installed on the ditch below the slope, but it also occurs on the gravel installed on ordinary road gutters, drainage ditches in residential areas, and gutters on reclaimed land. .

[0008] The problem to be solved by the present invention is to obtain an effective means for preventing dust and the like from flowing into a basin such as a side groove or a drain groove.

[0009]

Means for Solving the Problems A container lid of the present invention is a container lid used for a container such as a side groove or a drainage groove, characterized in that a stone material is filled in a frame body whose upper and lower surfaces can pass water. And

At least the upper surface and the lower surface of the frame body are made of a material such as a mesh body, a grid plate, and a perforated plate that allows water to pass through without interruption. Since the side wall does not necessarily need to be water permeable, it may be made of the same material as the upper and lower surfaces, or may be made of a normal plate material or the like.
For example, the entire frame body can be formed of a wire mesh.

When the frame body is formed by a wire mesh, the wire mesh is formed into a shape having a flange portion supported by a lid receiving portion at the upper end of the box. For the wire net, a wire net having a strength that can maintain the shape of the frame body when the stone is filled is used as a material, and a wire net with a mesh slightly smaller than the filled stone is used. For example, a wire having a diameter of 4 to 5 mm is used as a wire mesh of 20 to 30 mm, and the wire mesh is formed into a shape of a lid to form a frame. By filling a stone material in the frame body, a container lid is constructed.

When the frame body is formed of a wire mesh, it is preferable to attach a reinforcing frame to the portion corresponding to the peripheral wall of the frame body in order to prevent the frame body from losing its shape. As a reinforcing frame, bar material,
A lattice plate material, a plate material or the like can be used.

Further, the portion corresponding to the upper surface of the frame body can be opened and closed so that it becomes easy to wash or replace the soiled or clogged stone material for a long period of use. Further, a handle for carrying can be provided on the reinforcing frame attached to the portion corresponding to the peripheral wall of the frame body.

The stone material to be filled in the frame is large enough not to drop from the stitches on the lower surface of the frame. It is easy for water and sand to pass between the individual stone materials in the filled state, and dust and dead branches It is preferable to use a stone material having a shape such that there is a gap that does not allow the passage of such materials. It is also desirable to combine large and small stones to adjust the gap between the stones.

In the case lid 10 of this embodiment, a frame body 2 formed of a wire netting 1 is filled with a stone material 3, and a reinforcing frame 4 is attached to a peripheral wall and a bottom surface of the frame body 2.

The wire mesh 1 is a mesh body formed by weaving a steel wire having a diameter of about 4 mm so that the size of the stitches is about 25 mm.
As shown in FIG. 2A, the wire netting 1 is formed into a frame body 2 including a peripheral wall 21 having a large upper part and a smaller lower part, and a top wall 22 and a bottom wall 23. A box-shaped reinforcing frame 4 with a step shown in FIG. 2B is mounted around the peripheral wall 21 of the frame body 2. Further, steel bars 41 are attached to the lower end of the reinforcing frame 4 in a cross shape to reinforce the bottom surface 23 of the frame body 2.

As shown in the partial cross-sectional view of FIG. 1, the frame body 2 with the reinforcing frame 4 mounted thereon has the upper end of the block 53 when the cell lid 10 is placed on the upper end of the block 53 of the cell 50. The upper step of the peripheral wall 21 is formed in a shape having a flange portion that is supported by the lid receiving portion 53 a, and the lower step of the peripheral wall 21 is formed so as to fit inside the block 53.

The frame body 2 is filled with a relatively large stone material 3 and a relatively small gap stone material 3a to be filled in the gap to complete the container lid 10. In the state where the frame body 2 is filled with the stones 3 and 3a, the gap between the individual stones allows water and sand to pass through but does not allow dust and dead branches to pass through. It is prevented from flowing into 50.

Further, in the frame body 2 of this embodiment, as shown in FIG. 2A, the upper surface 22 of the frame body 2 is surrounded by the peripheral wall 21.
It is attached so that it can be opened and closed freely. By opening and closing the upper surface 22, the stones 3 and 3a can be easily taken in and out when the stones 3 and 3a are filled in the frame 2 and when the stones 3 and 3a are washed or replaced after long-term use. Becomes

It is made easy to hold the container lid 10 when it is attached to and detached from.

As described above, in this embodiment, the frame body 2 formed of the wire mesh 1 is filled with the stones 3 and 3a to form the container lid 10, so that it flows with water from the road surface or the slope. It prevents dust and dead branches from flowing into the basin 50. As a result, unlike the conventional case, dust or the like does not accumulate on the bottom of the basin 50, and water can flow in and out smoothly. In addition, since dust and the like do not accumulate on the bottom of the basin 50, the conventional deposit removal work is unnecessary.

When the reinforcing frame 4 is attached to the frame body 2, the frame body 2 is prevented from losing its shape and can be used for a long period of time. Further, by opening and closing the portion corresponding to the upper surface of the frame body 2, the stone materials 3 and 3a that have become dirty or clogged due to long-term use can be taken out from the frame body 2 and washed or replaced. You can easily. further,
Providing the handle 42 on the reinforcing frame 4 facilitates handling of the container lid 10.

The above embodiment is an example of the box cover applied to the square box installed in the gutter below the slope of the road. However, the box cover of the present invention can be applied to ordinary road gutters and houses. The present invention can be applied not only to square basins but also to circular basins, and can be applied to basins installed in drainage ditches of towns, side ditches of landscaping, and the like.

[0025]

According to the present invention, the following effects can be obtained.

(1) By filling a stone in a frame made of wire mesh to form a container lid, dust, dead branches and the like that have flowed with water are prevented from flowing into the container.
