JP2006063614A - Side ditch with water storage function - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a side ditch with the water storage function for preventing a high temperature rise in a city center part by a heat island phenomenon by paving of a road such as asphalt of the city center part. <P>SOLUTION: A drain part 8 and water reservoirs 9 and 9 partitioned by a partition plate 7 having the height lower than side plates 6 and 6, are arranged in parallel in the flowing water direction of a body 5 in the body 5 of the U-shaped side ditch. Water permeable holes 10, 10, 10 and 10 are arranged in a bottom part 11 for permeating a part of waster water flowing to the drain part 8 to soil under the body 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a side groove such as a roadway having a function of storing rainwater.

  In recent years, as paving of roads and the like in urban areas progresses, the soil is covered with asphalt and the like, and the cooling effect due to water evaporation of the soil is reduced, contributing to the heat island phenomenon.

In order to solve this problem, a water permeable road as shown in Patent Document 1 has been considered. However, since the water permeable hole is clogged with dust and the water permeability is lowered, periodic maintenance is required, and soil under the road Rainwater that has penetrated into the soil is not always retained as soil moisture, and most of it is washed away as groundwater, so if the day without rain continues for a while, the soil moisture will be used up and the effect cannot be demonstrated. There was a case.
JP 47-30132 A

  Then, this invention makes it a subject to provide the side groove | channel with a water storage function which prevents the high temperature of the inner city part by the heat island phenomenon etc.

  The present invention has been made to solve the above problems, and the first invention is a side groove with a water storage function, wherein one or a plurality of water storage portions are provided.

  2nd invention is a side groove | channel with a water storage function characterized by making part or all of the bottom part of a drainage part into a water-permeable structure in 1st invention.

  3rd invention is a side groove | channel with a water storage function characterized by providing the drainage part and the water storage part in parallel in 1st or 2nd invention.

  As described above, according to the present invention, it is possible to store rainwater while maintaining a general drainage function, and the stored water is consumed only for evaporation. You can expect. Moreover, the cooling effect by the water | moisture content evaporation from a soil can also be anticipated by making the bottom part of a drainage part permeate into soil as a water-permeable structure.

  In addition, by providing a plurality of water storage portions in the direction of water flow, even if they are installed as side grooves on a slope road, all the water does not flow down and remains in the water storage portion, so that a cooling effect can be exhibited.

  FIG. 1 shows an embodiment according to the present invention, in which 1 is a U-shaped side groove body, 2 and 2 are side plates of the body 1, and 3 and 3 are lower partition plates 4 and 4 than the side plate 2. It is a water storage section partitioned by.

  In such an embodiment, excess water is drained when the amount of water flowing into the gutter exceeds the capacity of the water storage unit 3, and when the amount is below the capacity, water is stored in the water storage unit 3.

  FIG. 2 shows a second embodiment according to the present invention, wherein 5 is a U-shaped side groove body, 6 and 6 are side plates, and 7 is a partition plate for partitioning the drainage portion 8 and the water storage portion 9 from the side plate 6. It is provided at a low height. Reference numerals 10, 10, 10, and 10 denote water-permeable holes provided in the bottom 11 of the drainage unit 8.

  In the second embodiment, the water flowing into the main body 1 passes through the drainage portion 8, and a part of the water is discharged to the soil below the lateral grooves through the water-permeable holes 10. When the amount of flowing water increases and the water level exceeds the partition plate 7, a part of the drainage flowing through the main body 1 is stored in the water storage unit 9.

  FIG. 3 shows a third embodiment according to the present invention, in which 12 is a body of an L-shaped side groove, 13 is a side plate, 14 and 14 are water storage sections, 15 is a drainage section, and 16, 16, 16, and 16 are drainage sections. It is a water-permeable hole provided in the bottom part 17 inclined.

  According to the third embodiment, most of the water drained from the road surface first flows into the water storage unit 14 and is stored therein. The overflowed water is drained through the drainage unit 15, and part of the water is passed through the water permeation holes 16. Is discharged into the soil below the main body 12.

1 shows Example 1 according to the present invention, where (a) is a plan view and (b) is a cross-sectional view taken along the line AA. FIG. FIG. 2 shows a second embodiment according to the present invention, in which (a) is a plan view and (b) is a cross-sectional view taken along the line BB. FIG. 3 shows Example 3 according to the present invention, in which (a) is a plan view and (b) is a cross-sectional view taken along the line CC.
