The gutter 1 shown in FIG. 1 is connected with a gutter 1a on the upstream side, a gutter 1b on the downstream side connected to the gutter 1a with a downward step, and a gutter 1b on the downstream side with a step. It is stepped from the gutter 1c. As shown in FIGS. 2 to 6, each of the gutters 1a, 1b, and 1c has a substantially U-shaped cross section in which the left and right side walls are inclined so as to expand upward, and the gutters 1a, 1c are shown in FIGS. As shown in FIG. 6, it has the same cross-sectional shape.

The upper end of the gutter 1b is at the same level as the gutter 1a, the bottom surface is flush with the bottom surface of the gutter 1c, and the depth to the bottom surface is larger than the depth of the gutters 1a and 1c, and is about twice or more.
In the gutter 1b, the angle members 2 are fixed to the lower portions of the left and right side walls of the gutter 1b by chemical anchors 3 (FIG. 7). A wedge-shaped receiving member 5 is attached on the horizontal portion of the angle member 2 along the inner side surface of the inclined side wall 1d. In this mounted state, the inner side surface of the receiving member 5 is vertical, and the horizontal portions 2a of the angle member 2 attached to the corresponding positions of the side walls of the gutter 1b project inward from the receiving member 5, respectively. The horizontal portion 2a protruding into the gutter from the receiving material 5 serves as a support portion for the earth and sand box 6.

A sediment box 6 as a cage for collecting sediment, which will be described later, is inserted from above between the vertical inner side surfaces of the left and right receiving members 5 mounted on the horizontal portion 2a of the angle member 2, and the inserted sediment box 6 is inserted. Is supported by being locked to the horizontal portion 2a of the angle member that projects inward of the gutter from under the receiving member 5 attached to the left and right side walls of the gutter 1b.

In the figure, 7 is a closing plate that is applied to the end of the gutter 1a from the lower side and hangs down to close the step with the gutter 1b, and 8 is applied to the end of the gutter 1c and directly above the gutter 1b. It is a gutter that closes the step.

The earth and sand box 6 as a cage for collecting earth and sand is a rectangular parallelepiped, and the entire other surface is formed of highly rigid expanded metal except that the upper surface is opened so that it is not easily deformed by the stored earth and sand. This expanded metal can be replaced with, for example, a high-rigidity wire mesh, a lattice, a punching metal, or the like. The same applies to the other expanded metals described below.

As shown in FIG. 8, the earth and sand box 6 also has a flange 7 protruding outward at the upper end of the side wall, and the earth and sand box in which a pair of earth and sand boxes 6 are paired flows so as to abut the flanges against each other. Multiple sets are arranged side by side in the direction. Then, in one earth and sand box 6 on the downstream side, a water stop plate 8 is attached under the flange of the downstream side wall along the downstream side wall on the horizontal portion 2a of the angle member 2, and the water stop plate 8 is attached. The entire surface of the downstream side wall of the earth and sand box 6 is covered to block rainwater so that rainwater cannot flow in and out between the earth and sand boxes 6.

As shown in FIG. 1, the earth and sand box 6 which is a combination of the earth and sand box 6 provided with the water stop plate 8 and the earth and sand box 6 without the water stop plate 8 as a pair is provided in the entire flow direction in the gutter 1b. The flanges are arranged side by side so as to abut against each other, a water channel 11 is formed on the gutter 1b under the earth and sand box, and rainwater passing through the bottom wall made of the expanded metal of the earth and sand box 6 passes through the water channel 11 and the gutter 1c. I am trying to leak to. The earth and sand mixed in the rainwater in the earth and sand box is filtered by the bottom wall made of expanded metal, and the sieved earth and sand are left in the earth and sand box and are stored.

In the earth and sand box 6, a dammed plate 13 made of expanded metal is provided upright on the water blocking plate 8 of the earth and sand box 6 in a suitable place, and earth and sand, dust, etc. mixed with rainwater overflowing on the earth and sand box 6 are collected. It is strained to prevent it from flowing out to the downstream side. More specifically, as shown in FIG. 5, another wedge-shaped receiving member 9 attached to both side walls of the gutter 1b is attached to the side wall of the gutter 1b in the same manner as the receiving member 5. Then, a dammed plate 13 made of expanded metal is inserted between the receiving materials 9 from above.

In the illustrated embodiment, one dammed plate 13 is provided, but a plurality of dammed plates 13 may be provided in the gutter 1b at appropriate intervals in the flow direction.

According to the present embodiment, rainwater mixed with earth and sand, dust, etc. passes through the gutter 1a through the gutter 1b, passes under the closing plate 8 and flows out to the gutter 1c (see FIG. 1), but in the gutter 1b, the first one. It flows into the second earth and sand box 6 through the earth and sand box 6 and then the side wall on the downstream side in the flow direction. The rainwater or the like that has flowed into the second earth and sand box 6 is blocked by the water stop plate 8 and does not flow out to the third earth and sand box 6. The rainwater or the like blocked by the water stop plate 8 is filtered at the bottom made of expanded metal in both the first and second earth and sand boxes 6, and the sieved earth and sand and dust are left in the earth and sand boxes. Then, the remaining rainwater containing earth and sand and dust under the sieve (hereinafter, rainwater including earth and sand and dust is referred to as "rainwater and the like") flows into the waterway 11 and gutters together with the rainwater and the like that have passed under the closing plate 8. It flows out to 1c.

As the sieved earth and sand and debris left in the earth and sand box collect in the earth and sand box, the outflow of rainwater and the like to the waterway 11 gradually decreases, and the rainwater and the like blocked by the water stop plate 8 are collected in both earth and sand boxes. It stays within 6 and gradually increases the volume of water.

When the rainwater or the like in both earth and sand boxes 6 is full, the rainwater or the like flowing from the gutter 1a overflows on both earth and sand boxes and flows into the third and fourth earth and sand boxes 6. After that, the same action as that of the first and second earth and sand boxes 6 described above is produced. The same applies to the nth and n + 1st earth and sand boxes 6.

In the last pair of earth and sand boxes 6, rainwater and the like pass through the side wall having no water stop plate, pass under the closing plate 8, and flow out to the gutter 1c.
Sediment and the like accumulated in the earth and sand box 6 are taken out from the earth and sand box 6 in a timely manner for cleaning and removal. Since the earth and sand box 6 is inserted between the receiving materials and is only supported on the horizontal portion of the angle material 2, it can be easily taken out by pulling up.

In the above-described embodiment, the earth and sand box 6 is entirely made of, for example, steel or hard resin and has high rigidity so as not to be easily deformed. However, the framework constituting the outline of the earth and sand box 6 is formed. If it is made of rigid steel or hard resin, or if a rigid member made of rigid steel or hard resin is attached, other wall parts do not have rigidity such as wire mesh or resin net. It can also be formed of a material. In this earth and sand box 6, if the framework has high rigidity, is solid, and is not easily deformed, the wall portion of the surface other than the framework is not rigid, and the stored earth and sand may be used to some extent. Even if it swells, there is no problem in practical use.

In the above embodiment, the horizontal portion of the angle member 2 is supported with an appropriate gap from the bottom wall of the gutter 1b, whereby the gutter 1b is provided with a water channel 11 under the earth and sand box. However, the earth and sand box 6 may be placed directly on the bottom surface of the gutter 1b. Further, the edge of the lower end of the earth and sand box 6 pushed in from above may bite into the inclined wall surface of the gutter 1b, and the earth and sand box 6 may be supported by the gutter 1b by the wedge effect. In either of the above cases, it is possible to eliminate the need for the attachment of the earth and sand box 6 and the tools and work for attaching the attachment as shown in the embodiment.

In yet another embodiment, pedestals are attached to both sides of the bottom of the gutter 1b or to the bottom of the groove, and the earth and sand box 6 is attached onto the pedestals. Under the earth and sand box, a water channel is formed between the pedestals on both sides or between the pedestal and the side wall of the gutter. The pedestal may also be formed hollow to allow rainwater or the like to pass through.

The pedestal that supports the earth and sand box 6 also needs only be placed at the bottom of the groove and does not require any other mounting tools or tools.
In the above embodiment, the earth and sand box 6 is provided with the water stop plate 8 and the dam plate 13, but the water stop plate 8 and the dam plate 13 are not always essential and may be deleted. In particular, as described above, when the earth and sand box 6 is landed on the bottom surface of the gutter 1 and placed directly, rainwater or the like can sequentially pass through the earth and sand box 6 and flow out to the gutter 1c without providing the water blocking plate 8. Is desirable.
