Abstract

The present invention relates to a drainage system and, more particularly, includes a water collecting well body having therein a water collecting space part open on upper and lower sides and installed underground, an inflow part for rainwater inflow from a road shoulder to the water collecting space part, a horizontal drainage part performing horizontal drainage in a case where the rainwater collected at the water collecting space part has a certain water level or a higher water level, and a fiber mat provided at the open lower end part of the water collecting space part, causing the rainwater stored at the water collecting space part to infiltrate into soil by means of lower-side passage, and filtering precipitates. According to the present invention, foreign substances such as solids are treated before rainwater inflow from a sidewalk and a road to a drainage facility. Then, the rainwater flows in. Accordingly, the service life and efficiency of the drainage facility can be improved. In addition, the drainage efficiency can be further improved by means of direct soil infiltration of precipitate-removed rainwater.

Description

[0001] The present invention relates to a pretreatment apparatus for rainwater drainage facility,

The present invention relates to a pretreatment apparatus, and more particularly, to a pretreatment apparatus for an excellent drainage facility capable of improving the lifetime and drainage efficiency of a drainage facility by removing foreign matter before introducing the collected stormwater into the drainage facility .

Generally, as the impervious surface of a city is increased due to packaging or the like, a sewage facility composed of rainwater collectors, conduits, and the like for draining rainwater is provided.

However, these sewage facilities have a problem that the amount of the excellent penetration into the soil is extremely small as the sewage is drained directly to the river or sea without the constitution for permeating the storm into the soil.

Particularly, during the rainy season in summer, the stormwater can not be received by stormwater due to the torrential rain, resulting in the formation of waterdrops, which can not pass people or pass the vehicle.

Also, there is a problem that the sewer lid or the collecting lid is damaged by the backflowing due to the surge of the drainage amount, or the lid is raised by the water pressure, causing secondary damage.

In order to overcome this problem, as disclosed in Japanese Utility Model Registration No. 20-0467111, a device capable of easily flowing backward when not only water is introduced but also a large amount of drainage is used.

However, such a device does not provide a source solution for drainage, and has nothing to do with the drainage efficiency, and also has a problem that the function of penetrating the storm with the soil is also deteriorated.

Also, since the collected rainwater contains foreign matter such as solid matter, there is a problem that the life of the drainage facility is shortened and the drainage efficiency is lowered.

Accordingly, there is an urgent need to develop a technique for removing foreign matter before the storm enters the drainage facility, thereby improving the lifetime and drainage efficiency of the drainage facility.

The drain filter 436 is provided inside the other end of the drain pipe 432 to filter the fine material contained in the rainwater.

The drain filter 436 is formed of a lightweight aggregate and is filled in the other end of the drain pipe 432.

The drain filter 436 may be manufactured by filling a plurality of lightweight aggregate materials in the net, and the drain plate 434 may be inserted into the separate drain pipe 432.

3, the water collecting hole 110 is formed in a quadrangular shape when viewed from a plane, and the fiber mat 500 is formed to correspond to a lower end of the water collecting hole 110. As shown in FIG.

The fiber mat (500) is produced by weaving at least one of coconut fiber and jute fiber.

Accordingly, the fiber mat 500 is environmentally friendly, minimizing contamination of the soil, allowing the collected water to pass downward easily, and also allowing the sediment to fall.

Here, an installation means (700) for installing the fiber mat (500) on the collecting body (100) is further included.

As shown in FIG. 4, the mounting means 700 includes a guide tab 710, a mounting bar 720, a mounting portion 730, and a mounting handle 740.

The guiding jaw 710 is provided at each corner of the collecting body 100.

The installation bar 720 has a predetermined length and is provided to be movable along the guide tabs 710.

The installation fixing part 730 is provided to fix the lower end of the installation bar 720 to the corresponding edge of the fiber mat 500.

Further, the installation handle 740 is provided at the upper end of each installation bar 720.

The plurality of installation bars 720 fixed to the fiber mat 500 are moved upward or downward along the guide tabs 710 so that the fiber mat 500 can be moved And can be installed or removed at the lower end of the shaft 110.

Thus, if the fiber mat 500 is clogged by the sediment and the rain can not penetrate into the soil, the new fiber mat 500 can be easily replaced.
