Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-function type gutter having a function of promptly draining rainwater from a roadway, a function of delaying it into a river or the like, and a function of recharging groundwater.

[0002]

2. Description of the Related Art Regarding road gutters, there is a demand for road management that drains rainwater as soon as possible so that rainwater accumulated on the road surface will not hinder the running of vehicles, and a large amount of rainwater. There is a relative need for river disaster prevention and sewage treatment to drain rainwater as slowly as possible so that the river will not be flooded or the capacity of the sewage treatment facility will be exceeded due to the inflow of water.

In recent years, it has been pointed out that harmful effects of draining and removing all rainfall water to rivers, that is, inhibition of tree growth, ground subsidence, groundwater salinization, etc., due to a decrease in groundwater level. The requirement for environmental conservation is added to recharge groundwater by returning as much water as possible to the ground.

In order to remove rainwater at an early stage, the bottom plate of the gutter body, which is joined in series to form a gutter, is formed in a downward slope from the upstream end toward the downstream end, and the length of the gutter is increased. It is sufficient to secure the required water transfer gradient along the direction. In the variable gradient type gutter disclosed in Japanese Utility Model Publication No. 56-51113, the upper portions of the left and right side plates of the gutter body are connected by horizontal beam portions at the front and rear ends, and the lower portions of the left and right bottom plates are entirely opened. The bottom slab concrete is placed at the laying site according to the water guide gradient.

In the procedure for constructing the variable gradient type gutter, after laying foundation stones on the bottom of the excavation trench in the ground and compacting them with a rammer or the like, the foundation concrete is placed by a ready-mixed car after a while. It After the basic concrete is hardened to a predetermined strength, a predetermined number of gutter main bodies are laid in sequence, bottom slab concrete is poured from the upper opening of the gutter main body, and leveled finish is performed in accordance with the designed water guide gradient.

However, in this variable gradient type gutter,
Since there are many processes such as compaction of foundation stones, placing of concrete, placing of floor concrete and even finishing, there is a problem that the construction period as a whole is long. Further, since it takes a lot of time to set the concrete from the ready-mixed concrete car, the road obstruction such as road closure and one-way traffic is given for a long time. The inability to pass water immediately after placing the bottom slab concrete is also a factor preventing the shortening of the process.

Further, since the bottom slab concrete must be cast and evenly finished from the relatively narrow opening of the gutter body, the work efficiency is poor, and the slope of the top surface of the bottom slab concrete is designed. It takes a lot of time to finish it according to the water transfer gradient. Since the finish is inaccurate in reality, it is pointed out that there are many examples of construction in which the required downflow speed and water flow rate are not obtained.

[0008] Furthermore, basic Kuriishi, basic concrete,
All of the processes related to the bottom slab concrete work are manual work, and as described above, each process is interrupted and chopped each time, which is a serious problem for construction workers. It is a construction method that cannot deal with the problems of shortage and aging.

[0009] This variable slope type gutter is emphasized only to quickly process the rainwater drainage, and cannot meet the above-mentioned requirements for river disaster prevention and environmental conservation. Is. Also, regarding the early drainage function, there is a problem in maintenance after installation. In other words, in reality, the top surface of bottom slab concrete is not always finished uniformly, and uneven portions are left, so mud and sludge easily accumulate in these uneven portions, and these act as flow-over resistance and drainage performance. Lower. It is necessary to remove mud etc. to recover the drainage performance, but since the upper opening of the gutter body is narrow, the work is not easy and it takes a long time, and it is often left in the middle of halfway It is also unsanitary.

[0010]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to improve the workability of laying, to easily cope with mechanization and labor saving of the work, and to easily maintain and manage the work after laying, and to prevent rain on the road surface. It is an object of the present invention to provide a multi-function gutter having both the function of early removal of water, the function of delaying inflow to rivers and sewerage facilities, and the function of groundwater recharge.

[0011]

The multi-functional gutter of the present invention has a midsole plate 4 housed between the left and right side plates 2 and 3 of the gutter body 1 in the following description with reference to the reference numerals in the accompanying drawings. The inner space of the gutter body 1 is divided into a rainwater drainage space 5 and a rainwater storage space 6, and the insole plate 4 is arranged so that the upstream end 4a is higher than the downstream end 4b. The water passage portion 7 opening to the rainwater storage space 6 is formed in the insole 4, and the water passage portions 9 and 10 opening to the laying ground 8 are formed in the gutter body 1.
It is formed on one or both of the bottom plate 11 and the side plates 2 and 3.

[0012]

Operation: A base is formed by compacting crushed stone, etc. at the bottom of the excavation groove on the road side, and a predetermined number of gutter main bodies are laid in series on the upper surface of the base, and the gutter is selected by an appropriately selected known joining method. The main bodies 1 and 1 are sequentially joined to form a side groove. After that, the support members 14 and 15 are attached to the left and right side plates 2 and 3 by the fixing members 12 and 13 fixed to the left and right side plates 2 and 3,
The insole plate 4 inserted into the inner space of the side groove main body 1 from the upper surface open portion is engaged with the support members 2 and 3 to support the insole plate 4 at a predetermined inclined position. Before or after accommodating the insole 4, the void between the laying groove and the gutter body is backfilled, and all laying work is completed.

The open upper surface of the gutter main body 1 is closed by a cover plate 16 in a conventional manner to prevent the wheels of the traveling vehicle from falling off and the foot of a pedestrian from falling down. The rainwater on the road surface passes through the water passage opening 17 such as the grating portion of the cover plate or the groove hole, and the gutter body 1
Flows into the inner space of. A part of the rainfall water that has fallen to the insole 4 flows down at a predetermined speed in the rainwater drainage space 5 due to the water guide gradient of the insole 4, and the rivers connected to the downstream side of the gutter. Flow into sewer treatment facility.

Another part of the rainwater is the water passage 7 of the insole 4.
Flows into the rainwater storage space 6 of the gutter body 1. Rainwater permeates into the laid ground 8 from the water passage portion 9 of the bottom slab 11 and the water passage portion 10 of the side plates 2 and 3 of the rainwater storage space 6. Depending on the relationship between the volume of the rainwater storage space 6 and the total cross-sectional area of the water passages 9 and 10 and the amount of rainwater that has flowed in, a portion of the rainwater stays in the rainwater storage space 6 for a certain amount of time, Even after the stop, rainwater continues to penetrate into the ground 8.

[0015]

Embodiment In the embodiment shown in FIGS. 1 and 2, the gutter main body 1
Is a U-shaped gutter with the entire upper surface open.
The lid plate 16 is fitted onto the lid receiving stepped surface 18 on the upper side of 3. A sand wash layer 20 is formed at the bottom of the excavation groove 19 of the ground 8, and a rainwater permeation induction layer 21 is provided on the upper surface side of the sand wash layer 20 by a void forming member such as crushed single-grain stone. The rainwater permeation guide layer 21 by crushed stones is also provided on the ground portion adjacent to the left and right side surfaces below the gutter body 1. The rainwater permeation guide layer 21 is surrounded by a civil engineering sheet 22.

In this embodiment, not only the bottom plate 11 is provided with the water passage portion 9 but also the left and right side plates 2 and 3 are provided with the water passage portion 10. However, only the side plates 2 and 3 are provided with the water passage portion. When it is provided, and when the water passage 10 is provided as high as possible in the rainwater storage space 6, the pollutants mixed in the rainwater from the road 23 and the sidewalk 24 are deposited on the bottom plate 11, Since only clear water infiltrates into the soil from the water flow section 10, the problem of soil pollution associated with underground infiltration of rainfall water is reduced. Penetration of contaminants can be considerably reduced by inserting a sedimentation basin in the middle of the gutter.

The space 6 for storing rainwater is filled with a void holding member 25 such as crushed stone or crushed stone. The rainwater is filled and stored in the space between the space holding members 25, 25,
It gradually penetrates into the soil from 10. Further, the water flow in the rainwater storage space 6 is disturbed by the gap holding member and becomes slow. Therefore, even if the rainwater storage spaces 6 and 6 communicate with each other over the entire length of the gutter and the rainwater storage space 6 is directly connected to the water inlet of a river or the like, the delay of the inflow to the river or the like is effectively achieved. To be done.

The insole 4 is made of a material such as a reinforced concrete plate or the like, which has a mechanical strength higher than a certain level and is resistant to corrosion. The insole plate 4 is produced under quality control at the factory, and the upper surface portion through which the rainwater flows is formed smooth so that the flow resistance is small. The insole 4 can be used in combination with a plurality of sheets.

The water passage portion 7 of the insole 4 and the water passage portions 9 and 10 of the gutter main body 1 are circular through holes. The water passage may be formed of a square through hole, a circular or square diameter opening, or the like. The whole or a part of the insole plate 4 and the side plates 2 and 3 may be formed by molding a porous material or may be formed by a mesh material. The same applies to each of the following examples.

Mutual joining of the gutter main bodies 1 and 1 does not require casting and curing of basic concrete, and is not affected by weather conditions such as rainfall or environmental conditions of the laying site such as spring water, and the construction period is very short. Therefore, it is possible to employ an eccentric seat plate type joint structure that can obtain a joint that is sufficiently strong against uneven settlement.
