とを可能にした複合機能型側溝に関するものである。BACKGROUND OF THE INVENTION The present invention relates to a multi-function type gutter having a function of promptly draining rainwater such as a roadway, a function of delaying it to flow into a river or the like, and a function of recharging groundwater. Prevents pollution caused by contamination of pollutants, pollutants, dust, etc. that occur in the ground or groundwater, and prevents clogging that significantly reduces the permeation function. Furthermore, when the clogging prevention function declines, the functional recovery is ensured. The present invention relates to a multi-function type gutter capable of being implemented.

Description of the Related Art As for road gutters, there is a demand for road management that drains rainwater accumulated on the road surface as soon as possible so that it does 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 the rainwater as slowly as possible so that the river will not be flooded or the capacity of the sewage treatment facility will not be exceeded due to the inflow of water.

わっている。In recent years, it has been pointed out that harmful effects of draining and removing all rainfall water to rivers, that is, obstruction of tree growth, ground subsidence, seawater salinization phenomenon, etc., due to a decrease in groundwater level. There is an increasing demand for environmental conservation to recycle groundwater as much as possible to recharge groundwater.

打設している。In order to remove the 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 to 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 parts of the left and right side plates of the gutter body are connected by horizontal beam parts at the front and rear ends, and the lower parts of the left and right bottom plates are entirely open. , At the laying site, bottom slab concrete is placed in line with the water guide gradient.

計導水勾配に合わせて均し仕上げが行われる。In the procedure for constructing the variable slope type gutter, after foundation stones are laid on the bottom of the excavation groove in the ground and tampered with a rammer or the like, the concrete is placed by a ready-mixed concrete car after a while. After the basic concrete has hardened to a predetermined strength, a predetermined number of gutter main bodies are laid in sequence, bottom slab concrete is poured from the top opening of the gutter main body, and leveling and finishing is performed according to the designed water transfer gradient.

短縮を妨げる要因になっている。However, in this variable gradient type gutter,
There is a problem that the overall construction period is long because of the large number of steps such as compaction of foundation stones, placing of concrete, placing of slab concrete and leveling. Further, since it takes a lot of time to place concrete from the ready-mixed concrete car, it causes traffic obstruction such as road closure and one-way traffic for a long time. Inability to pass water immediately after placing the slab concrete is also a factor that impedes the shortening of the process.

ていない施工例も少なからず指摘されている。Further, since the bottom slab concrete must be poured and leveled and 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 to introduce water. It takes a lot of time to finish on a gradient. Since the finish is inaccurate in reality, it is pointed out that there are many examples of construction in which the required flow rate and water flow rate are not obtained.

All of the processes related to slab concrete require manual work, and as described above, each process is interrupted and chopped into pieces, resulting in a shortage of construction workers, which is currently a serious problem. This is a construction method that cannot deal with the problem of aging.

もある。[0009] This variable slope type gutter is emphasized only to quickly process the rainwater, 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 irregularities are left behind, so mud and sludge are likely to accumulate in these irregularities, and these act as drainage resistance. Reduce performance. 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 a halfway It is also unsanitary.

That is, in the methods (a) to (e), the outflow suppression amount and the stored permeation amount are small. For example, the method of infiltration masu is a point installation and the amount of infiltration is small.The infiltration underground trench method is a point and a line, but both are insufficient, and the underground burial construction cost increases and clogging occurs. It is difficult to recover the function when it hits. The method using the penetrating U-shaped groove is less effective and easily causes clogging, and it is difficult to recover the function of the clogging.

This means that the amount of water flowing out to the river and the sewer main becomes large, and it is necessary to increase the river water supply and increase the capacity of the sewer main, which increases the project cost and costs a lot of maintenance. . Also, in the case of combined sewerage, the capacity of the terminal sewerage treatment facility will be exceeded, and there is a risk that untreated sewerage will flow into rivers and the sea.

It is an object of the present invention to provide a multi-function type gutter having both a water intake function, a storage function, and a permeation function, which can easily recover the function when clogging occurs.

Sequential bonding is performed by a known bonding method to construct a multi-function side groove. In this case, the water intake column 7 attached to the standing side wall 2 of the upper drainage space 18 is attached at the factory or at the time of laying. After the bottom slab 15 of the upper drainage groove space 18 is mounted, the laying groove and the vacant space of the gutter body 17 are backfilled, and the laying work is completed.

The water flows into the inner space of the gutter main body 17 from the water passage openings such as the grating portion 8 and the groove hole. Part of the rainwater that has fallen to the bottom slab 15 flows down at a predetermined speed in the upper drain groove space 18 due to the water guide gradient of the bottom slab 15 and flows into the river or sewer treatment facility connected to the downstream side of the gutter.

The open upper surface of the gutter main body is closed by a cover plate 38 in accordance with a conventional method to prevent the wheeling of the traveling vehicle and the foot of a pedestrian from falling. A slope is provided on the road surface 37 in the direction of the gutter so that rainwater can quickly flow into the gutter. Rainwater on the road surface flows into the upper drain from the grating part of the cover plate 38 or the like. The lower storage grooves 19, 19 of the left and right multifunctional side grooves 17 are communicated with each other by a penetration trench pipe 51.
