Description

[Detailed description of the invention] The present invention is a non-sediment type curb drainage pipe unit that has a sub-drainage section for draining a small amount of rainwater and a main drainage section for discharging a large amount of rainwater. Sediment and dust that tends to accumulate in the drainage channel due to rainwater is retained on the permeable material surface covering the top surface of the sub-drainage channel section, allowing only the rainwater to pass through, and this sediment is removed by a sweeper and deposited inside the unit. It is intended to prevent this from happening.

Fine earth and sand carried by the wind and vehicles, asphalt dust scraped off by vehicles, and tire wear dust are scattered on the bridge road surface. This rainwater flows into the roadside drainage pipes, but because the drainage pipes cannot be designed to have a large slope on bridges, they gradually accumulate inside the bridge over a long period of time, becoming compacted and reducing drainage efficiency. Eventually, the water overflows, so regular cleaning and management is required, which requires a great deal of effort and expense.

Therefore, attempts have been made to make cleaning easier by making the lid open and close or by drilling a long hole in the lid, but this is extremely inefficient as the work is done manually. The inside of the drain pipe could be cleaned by increasing the length of the sweeper's brush, but this would damage the road surface pavement, making this impossible.

The present invention allows cleaning with this sweeper to be applied without having to use a long brush.
It has a front wall that stands up from the front and rear edges and the middle of the bottom plate and forms main and sub-drainage channels that are parallel to each other, a rear wall that is higher than this, and a partition wall that is lower than the rear wall, and the upper surface of the main drainage channel is directed toward the partition wall. The sub-drainage channel is covered with a lid that can be opened and closed, and the upper surface of the sub-drainage channel is covered with a water-permeable material.

According to this, a normal amount of rainwater passes through the permeable material and flows into the sub-drainage channel section, and earth and sand are captured by the water-permeable material and do not flow into the sub-drainage channel section or the main drainage channel section. If this sediment accumulates on the permeable material to a certain extent, the water permeability to the sub-drainage channel will decrease, so if you use the brush of the sweeper to reach over this accumulated layer and scrape it off, this water permeability will increase again. Rise. If the clogging becomes severe after long-term use, the water-permeable material can be replaced with a new one. In addition, the width of this water-permeable material is smaller than the width of the tires of a large vehicle, so the wheel load is not directly applied to it, and the water-permeable material itself has a considerable load-bearing capacity, so damage caused by the wheels is unlikely. Unthinkable.
In the case of heavy rain, there are two types of rainwater: one enters the sub-drainage channel through the permeable material, and the other enters the main drainage channel through the drainage hole on the slope of the lid, but both parties work together to drain a large amount of rainwater. . Open the lid of the main drain and clean it as necessary.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is a bottom plate, 2 is a front wall that stands up from the front edge of the bottom plate 1, 3 is a rear wall that stands up from the rear edge of the bottom plate 1, and 4 is a partition wall that stands up from the middle of the bottom plate 1 and is lower than the rear wall 3. There is. These walls 2, 3 and 4 form a main drain section 5 and a sub drain section 6 which are parallel to each other. Reference numeral 7 is for covering the main drainage channel section 5 with a lid, and a drainage hole 9 that is long in the direction of the main drainage channel section 5 is bored in the slope section 8 that extends downward in the direction of the partition wall 4 . This lid 7 is appropriately secured to the partition wall 4 and the rear wall 3 so as to be removable. In the illustrated example, the locking is performed as follows. That is, a locking portion 10 is formed downward at the lower end of the slope portion 8, square notches 11 are provided from the lower end at appropriate intervals in the length direction of the locking portion 10, and these are connected to the main part of the partition wall 4. The dowels 12 are fitted into square dowels 12 planted at similar intervals on the side of the drainage channel 5. Further, a horizontal portion 13 is formed at the upper end of the slope portion 8, and the end thereof is bent downward to form a locking portion 14, and similarly to the above, a horizontal portion 13 is formed at appropriate intervals in the length direction of the locking portion 14. Square notches 15 are provided from the lower end, and these are fitted into square dowels 16 implanted at the same spacing on the main drainage channel 5 side of the rear wall 3. Furthermore, in order to increase the load resistance, support pieces 17 that come into contact with the lower end surface of the locking part 14 are fixed to the rear wall 3 at appropriate intervals. These configurations are only examples of locking the lid 7, and a hinge opening/closing type, a palms-clasp type, etc. can also be adopted.
On the other hand, the upper surface of the sub-drainage channel section 6 is covered with a water-permeable material 18. This water-permeable material 18 may be a commercially available product, and should preferably be one that is resistant to clogging, has load-bearing properties, and has little deterioration over time. Various methods of covering this can be considered, but
In this example, it looks like this: Sub-drainage section 6
A support plate 19 of an appropriate length and having a width that matches the inner diameter of
Attach them at appropriate intervals along their length. A reinforcing plate 20 is then fixed between the support plate 19 and the bottom plate 1. The front wall 2 side of the support plate 19 is made to stand up along this side, and its upper end is bent horizontally to form a restraining piece 21, and the upper end of the partition wall 4 is also bent to face this restraining piece 21 to form a restraining piece. 22, the water-permeable material 18 is stable and will not escape even if subjected to impact. If a window 23 is opened at the lower end of the partition plate 4, the main and sub-drainage channels 5 and 6 can be shared.

In the drawings, M is mortar, P is pavement layer, S is floor slab, J is joint board, and A is anchor.

This unit is installed as usual on the deck of the road side of the viaduct using mortar M, and with the surface of the water-permeable material 18 located approximately on an extension of the surface of the pavement layer P. Similar units at the ends of the units are successively connected to the sluice through the joint plates J, and are connected to the vertical pipes at predetermined positions, as in the past.
In the case of a small amount of rainfall, the rainwater flowing on the paved surface comes to the surface of the permeable material 18 and permeates there, and the water flows through the sub-drainage channel section 6.
and flows down the slope along the slope. Sediment and the like that are on the surface of the pavement layer P and have flown with the rainwater are captured by the water-permeable material 18 and do not accumulate in the sub-drainage channel section 6. In the case of heavy rain, the amount of rain that passes through the permeable material 18 is not enough to absorb the rain, and the rain reaches the slope part 8 of the lid 7, and the drainage hole 9
It flows down through the main drainage channel section 5 and is discharged. If dirt or the like accumulates on the surface of the water-permeable material 18, by operating a sweeper and scraping it off, the water permeability efficiency can be restored to its original level. If the water permeability efficiency decreases due to clogging due to long-term use, use water permeable material 18.
You can replace it with a new one.

According to the present invention, since the upper surface of the sub-drainage channel is covered with a water-permeable material, it is possible to prevent soil, etc. from accumulating and hardening in the sub-drainage channel and main drainage channel, reducing drainage efficiency, and removing it using a sweeper. This has the effect of dramatically improving work efficiency and making maintenance easier and cheaper.
