Description

  The present invention relates to a side groove block, and more particularly to a side groove block that can discharge wastewater that is likely to overflow into the nearby soil or a reservoir.

  A large number of gutter blocks are embedded on the side of a road to constitute a drainage channel, and various types have been proposed in recent years, but most of them are integrally formed of concrete. In such a side groove block, a groove cover or a grating is placed and stored in a mounting step portion formed on the inner side of the upper end of the side wall so that the upper surface of the groove cover or the grating is substantially the same as the road surface. In addition, direct drainage from the road into the gutter block can be performed.

  Such a conventional gutter block is very effective because it can drain not only the drainage collected in the drainage channel but also the rainwater falling on the road to other places. However, if the amount of drainage drained through the drainage channel exceeds the drainage capacity, the drainage of the rainwater on the road becomes impossible as well as overflowing from the side groove onto the road (so-called overflow).

  Thus, in this type of gutter block, it is conceivable that a part of the drainage is drained to a place other than the gutter block such as underground, for example. There are various technologies as proposed in

  “The lateral groove pipe for permeable paved road and its arrangement structure” described in Patent Document 1 is “a side groove pipe embedded in the side edge of the permeable paved road, and a large amount of rainwater such as rain water that falls temporarily concentrated” By constructing and arranging rainwater to absorb and supply water, the permeated rainwater on the road is supplied to the ground as much as possible to reduce sewage treatment operation, and the water permeability of the road can be discharged quickly and efficiently. The purpose is to make full use of the utility, and as shown in FIG. 9, the drainage channel 3 is connected to one side wall 2b of the groove tube body 2 having the main drainage channel 3 along the length direction. A water-absorbing hole 6 is formed, and a water supply hole 7 communicating with the drainage channel 3 is formed in the other side wall 2c to form the side groove tube 1. The side groove tube 1 is formed along the side edge of the permeable paved road. The water absorption hole 6 is buried on the road side, and the water supply hole 7 is arranged on the opposite road side. Those having a structure.

  The “drainage pavement side gutter culvert for drainage pavement” described in Patent Document 2 is a “capped side gutter culvert method that continuously drains rainwater that has penetrated into the pavement and surface water that does not penetrate into the pavement. It is made for the purpose of “discharging at the shortest distance into the side groove without passing through the gap between the lid plate and the inner surface of the side groove”, and as shown in FIG. Protruding line (8) is provided, drainage hole (11) penetrating from bottom corner (4) along drainage pavement side edge under lid in side groove, or vertical groove (10) and upper end on side wall outer surface The drainage holes (11) connected in a 14a shape and penetrating under the lid in the side groove are arranged at an appropriate interval. "

  The "water storage system" described in Patent Document 3 is made for the purpose of "retaining drainage water such as rainwater in a water storage space provided in the basement so that the stored water can be used as drinking water". 11, “the first water tank 1, the first side groove 2 as a water inflow path connected to the water inlet 12 of the first water tank 1, and the water purification layer side A second water storage tank 3 communicating with the first water storage tank 1 through a first outflow hole 13 provided, and discharge holes 14 provided in the first water storage tank 1 and the second water storage tank 3, respectively. The first and second water guide pipes 4 and 5 communicated with each other by 22 and the second side groove 6 as a drainage channel connected to the water discharge port 15 provided in the first water storage tank 1. In the water storage system, a space support for forming a water holding space in the first water tank 1 is used. The frame member 1a and stacked, those having a structure such that part of the provision of the purified water layer 11 as a cleaning unit ".

The “perforated drainage ditches and basins” described in Patent Document 4 are “effectively utilizing natural water without waste by mutually recirculating running water and spring water, helping to prevent ground runoff disasters, and even destroying the environment. The purpose is to provide drainage side ditches and water collecting basins that lead to the suppression of water flow, and as shown in FIG. 12, a plurality of holes 1 are provided in the U-shaped side ditches and basin to recirculate running water and spring water. Natural water can be used effectively without waste, and the ground spring water from long-term heavy rain can be absorbed and discharged to help prevent ground drainage disasters, and this product can be commercialized by recycling industrial waste plastics. ”.

However, the technique of Patent Document 1 may be capable of “absorbing and supplying a large amount of rainwater such as rainwater that is concentrated temporarily”, but has a very complicated structure as shown in FIG. Therefore, it seems to be very difficult to integrally form this with concrete. (Difficulty of manufacture) Further, the “water absorption hole 6” opened on the road side is highly likely to be “clogged”, and it is considered that an effective function cannot be exhibited over a long period of time. (Difficulty in sustaining functions)
Further, even in the technique of Patent Document 2, it seems that the “drain hole 11” shown in FIG. 10 is very small, and the manufacture of such a drain hole 11 is difficult only for a concrete block. Instead, it is considered that it is likely to be “clogged” as in the case of Patent Document 1 described above.

Furthermore, the technique of Patent Document 3 also has a very complicated structure as a whole as shown in FIG. 11, and not only is it difficult to select the installation location, but the cost is also enormous. It seems to take. (Lack of economic efficiency)
And in the technique of patent document 4, as shown in FIG. 12, since it forms the "round hole 1 for water flow" also in a bottom face, it always drains from this round hole 1 to the lower side. Although there may be no “drainage overflow” problem, the soil in the soil near the gutter will always be infiltrated, which not only weakens the ground, but in some cases It is possible that the underside gutters may be scoured by the drained water. (Ground softening and scouring)
As described above, the conventional gutter block has advantages and disadvantages, and in particular, little consideration has been given to overflowed drainage.

Therefore, the present inventors, for this type of gutter block,
(1) It can be integrally molded with concrete and is easy to manufacture. (2) Only the overflow drainage that exceeds the capacity of the gutter block should be discharged into the nearby soil. (3) Since overflow drainage often occurs temporarily, it slows the penetration of overflow drainage into the soil even after that time has passed. The present invention has been completed as a result of various investigations on how to make it possible to be able to be performed.

  That is, the object of the present invention is to provide a gutter block that can be easily manufactured, can discharge only overflow drainage, and can prevent softening or scouring of the nearby ground. There is to do.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“ A side groove block 10 having a U-shaped cross section, a groove lid or grating 13 mounted on a mounting step portion 11 a formed on the inner upper portion of the side wall 11, and a water reservoir 15 provided below the bottom surface 12 . Because
Outside or inside at least one side wall 11 of the groove block 10, is opened to置段portion 11a near the mounting of the upper end portion 14a, an overflow passage 14 with Keru settings which is opened to the lower end 14b to the bottom surface 12 near
Side groove block 10 characterized by filling water drainage 15a in drainage basin 15 "
It is.

That is, as shown in FIGS. 1 to 4, the side groove block 10 according to the first aspect of the present invention is basically U-shaped in cross section and is placed on the mounting step portion 11 a formed on the inner upper portion of the side wall 11. Mizofuta or grating 13 is one that was placed. Here, the bottom surface 12 of the side groove block 10 is blocked . The reason is that the drainage channel formed by the side groove block 10 is used for normal drainage, that is, the side groove block 10 is normally formed. drainage channel performs drainage to distant by passing a, when there is a temporary heavy rain, outside the groove block 10 only overflow drainage to be leaving overflow from the groove block 10, i.e. the lower side and near This is because we want to drain the water.

  The gutter block 10 is provided with an overflow passage 14 having an upper end portion 14a opened near the mounting step portion 11a and a lower end portion 14b opened near the bottom surface 12 outside or inside at least one side wall 11 thereof. Is. The overflow passage 14 may be formed by an overflow pipe 20 connected to the side wall 11 as shown in FIGS. 1 to 3, but may also be formed directly in the side wall 11 as shown in FIG. is there.

  Regardless of whether the overflow passage 14 is formed directly in the side wall 11 or the overflow pipe 20 is used as the overflow passage 14, the upper end portion 14a is important in any case. It is opening near the part 11a, and the lower end part 14b is opening near the bottom face 12. This is because the side groove block 10 allows only the overflow drainage exceeding its capacity to penetrate into the soil in the vicinity of the side groove block 10, so that the upper end portion 14a of the overflow passage 14 is first placed on the mounting step portion 11a. It must be opened in the vicinity to receive only overflow drainage, and the lower end portion 14b of the overflow passage 14 must be opened in the vicinity of the bottom surface 12 in order not to return the received overflow drainage into the side groove block 10. Because it must be done.

  It should be noted that a “net” or “lattice” for preventing fallen leaves and dust from entering the upper end portion 14 a of the overflow passage 14 is preferably provided. Further, the maximum diameter of the overflow passage 14 should be such that the strength of the side wall 11 is not impaired. If the minimum diameter is about 3 to 5 cm, there is almost no fear of clogging.

  When the overflow passage 14 is constituted by the overflow pipe 20, a hole is formed in the side surface of the side wall 11 so that the overflow pipe 20 can be inserted, and the side groove block 10 is installed in the hole at the construction site. The upper end portion 14a of the overflow pipe 20 may be inserted. Further, an insertion portion 11b is formed on the side end surface of the side groove block 10 as shown in FIG. 2, and the insertion portion 11b on the side of another side groove block 10 installed adjacent to the side groove block 10 is used. The overflow pipe 20 may be inserted into the formed hole.

  If the lower end of the overflow pipe 20 is opened toward the outside of the gutter block 10 as illustrated in FIG. 3, it is only possible to prevent softening or scouring of the nearby ground. The mortar can be attached to the lower side of the gutter block 10. A water absorbing material 15b such as grits is laid on the lower side of the side groove block 10, the side groove block 10 is placed thereon, and the lower end portion 14b of the overflow passage 14 or the overflow pipe 20 is connected to the water absorbing material. If it opens in 15b, overflow drainage can be osmose | permeated in the said water absorption material 15b, and the temporary water retention of the overflow drainage by the water absorption material 15b can be performed.

Therefore, the side grooves block 10 of this, first, can be produced integrally simply by concrete, can discharge only the overflow drained by an overflow passage 14, a soft reduction and scouring of the ground in the vicinity of the installation was It can be prevented from being generated.

Also, in the gutter block 1 0 This, Ru opening of Setea the lower end portion 14b of the overflow passage 14 to the reservoir masu 15.

At the side groove blocks 1 0 this, as shown in FIGS. 5 to 7, a water mass 15 is provided on the lower side of the bottom surface 12, opening the lower end portion 14b of the overflow passage 14 or an overflow pipe 20 in the water mass 15 in the I'm allowed.

Is, at the side groove block 10, the overflow drainage is supplied to the water storage masu 15 by the overflow channel 14 or an overflow pipe 20. In other words, the overflow drainage that is temporarily generated is stored in the reservoir 15 through the overflow passage 14 or the overflow pipe 20, so that it does not overflow on the road or the like. Since the drainage channel can be configured in the same manner, the overflow drainage is discharged to another location through the drainage channel by the reservoir 15.

  Of course, as shown in FIGS. 5 and 6, the water storage tank 15 may be configured as a separate body from the upper side groove block 10, and as shown in FIG. You may comprise as an integral thing. 5 and FIG. 6, when configured as a separate body from the upper side groove block 10, the use as shown in FIGS. In the case where it is configured to be integrated with the side groove block 10 as shown in FIG. 7, the manufacturing process can be simplified.

Therefore, the side grooves block 1 0 This is can be integrally produced simply by concrete, can discharge only the overflow drained by an overflow passage 14, it does not generate a weak reduction and scouring of the ground in the vicinity of the installation was It is something that can be done.

  In the side groove block 10, the water absorbing material 15 a is filled in the drainage trough 15.

  That is, in this gutter block 10, as shown in FIG. 5, the water reservoir 15 is filled with the water absorbing material 15b, and it is possible to temporarily retain the overflow drainage introduced by the water absorbing material 15b. Is. As this water-absorbing material 15b, a synthetic resin raw material having a large number of water retaining holes, for example, sponge or other equivalents can be used as well as the above-mentioned “grindstone”.

  The overflow drainage is temporarily retained by the water absorbing material 15b, so that the drainage from the drainage port 15a is not abruptly performed. That is, the overflow drainage introduced into the reservoir 15 is once stored in the reservoir 15 and permeates into the surrounding soil through the drainage port 15a with a lapse of time. The same applies to the water that has entered from the surrounding soil, not the overflow drainage. For this reason, the rapid discharge of the overflow drainage is suppressed, and the overflow drainage gradually permeates into the surrounding soil and is not scoured.

  Therefore, the side groove block 10 according to the first aspect of the present invention exhibits the functions described above and can further suppress the occurrence of scouring.

Furthermore, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is the gutter block 10 according to claim 1 ,
“A drainage port 15a is provided in the reservoir 15”
It is.

That is, in the side groove block 10 of the second aspect, as shown in FIGS. 5 to 7, which is provided with drain outlet 15a at its water mass 15, thereby, as the water mass 15 is drainage If not configured, the overflow drainage introduced through the overflow passage 14 or the overflow pipe 20 into the reservoir 15 can be soaked in the surrounding soil from the drainage port 15a with time. The drain port 15a may be formed as a relatively large hole, and a nonwoven fabric, a net, or the like may be disposed inside.

  That is, in this gutter block 10, since the drainage port 15a formed in the reservoir 15 is buried in the soil, the overflow drainage once stored in the reservoir 15 passes through the drainage port 15a to the surrounding soil. It penetrates inside. This means that scouring is not caused by overflow drainage, and conversely, excess water in the surrounding soil can be guided into the reservoir 15 when overflow drainage does not occur. Also means.

Therefore, the side grooves block 10 of the second aspect, in addition to exhibit similar features of the first aspect, without generating the scouring, it is possible to penetrate the overflow drainage in the soil surrounding, also overflow When drainage is not generated, excess water can be stored.

As described above in detail, in the present invention,
“ A side groove block 10 having a U-shaped cross section, a groove lid or grating 13 mounted on a mounting step portion 11 a formed on the inner upper portion of the side wall 11, and a water reservoir 15 provided below the bottom surface 12 . Because
Outside or inside at least one side wall 11 of the groove block 10, is opened to置段portion 11a near the mounting of the upper end portion 14a, an overflow passage 14 with Keru settings which is opened to the lower end 14b to the bottom surface 12 near
Filling the drainage basin 15 with the water absorbing material 15a "
