Description

Technical Field [0001] The present invention relates to a GRATING FILTER APPARATUS OF DRAIN-OUTLET,

The present invention relates to a drain hole grating filter, and more particularly, to a drain hole filter having a very excellent filter performance, and is very convenient for collecting and collecting foreign matter. In addition, since the structure is simplified and the manufacturing process is simplified, To a drain hole grating filter.

In a variety of floor spaces having roads or arbitrary spaces, drainage holes connected to drainage lines at predetermined distances are provided so that rainwater that has fallen on the road surface can be smoothly discharged through the drainage holes.

Since the drainage port is a simple opening that is opened to the road surface, various kinds of waste such as sand, stone, tree branches, fallen leaves, cigarette butts, etc. may be introduced, and these may cause clogging of the drainage port and the drainage passage.

Therefore, a steel grating on the lattice is provided at the inlet of the drain hole to allow the inflow of rainwater while preventing the penetration of relatively large foreign matter.

However, in the case of snow or rain as in the known fact, cigarette butts, fallen leaves or other garbage that has been thrown on the road are drained by flowing rainwater along with rainwater. Normally, the drain pit is covered with a cover such as a grill, so that large sized trash is filtered, but a cigarette butt or other small trash passes through the grill and flows into the drain pit.

The drain pit is provided with a drain pipe leading to the main drain pipe of the underground, and the drain pipe may be narrowed or clogged due to various kinds of dirt introduced as described above. Also, when various sludge flows into the main sewer pipe, it accumulates in the main sewer pipe and it becomes necessary to dredge it.

As is known, dredging of a sewer pipe is costly and, in some cases, if it is not possible to dredge it, it is necessary to replace the sewer pipe, so that there is a problem that huge facility operation cost is required. In addition, since the dirt discharged through the main sewer pipe is drained to the ground water or the river, the dirt on the road is eventually washed away by the rainwater, thereby contaminating the river or the ground water.

In order to solve such a problem, Korean Patent Laid-Open No. 10-2014-0000178, entitled 'Grating Filter for Road Drainage', will be described. As shown in FIG. 1 and FIG. 2, a plurality of filter modules are constructed and installed outside the steel grating .

The above-mentioned prior art has an advantage that it is very easy to arrange foreign matters because the filter can be easily installed and dismantled by an operator.

Further, since each filter module has a relatively high height, there is an advantage that the foreign matter collecting capacity can be maximized.

However, in the case of the conventional art, when drainage is introduced in a short period of time such as a rainy season or a localized heavy rainstorm, external foreign substances are introduced at the same time, so that the drainage property can be lowered due to foreign substances collected suddenly.
