Description

TECHNICAL FIELD [0001] The present invention relates to a sewage pipe malfunction isolation device,

The present invention relates to a sewage pipe malodor shielding device for preventing a malodor generated in a sewer pipe from flowing back to the ground, and a construction method thereof.

Generally rainwater-like stormwater is discharged to rivers and rivers through sewage pipes connected to the roadside fixtures.

However, in the dry season when there is no stormy stream, gaseous hydrogen sulphide (H2S) is generated while the sludge is decayed in the sludge sediment layer which remains in the sewer pipe.

If the gas H2S is lighter than air and left untouched, the sewer pipe becomes a malodor moving path and flows back to the ground. The odor that flows back to the ground causes discomfort to the people moving there and pollutes the air It causes.

In addition, in the case of a sewer pipe having a part of polluted water, a harmful insect such as a mosquito hatches, and hatching mosquito larva penetrates into a residential area through a sewer, and pathogens caused by insect pest have a problem of hindering environmental hygiene.

Therefore, in order to prevent infiltration of malodor, noxious gas and insect pest that has flowed backward from the sewage pipe, the apparatus disclosed in Japanese Patent No. 10-1024146, as shown in Fig. 1, is equipped with an excellent discharge pipe 310 A forward elastic regulating bar 211 and a rear elastic regulating bar 222 which extend so as to be elastically adjustable to the front elastic ring 210 and the rear elastic ring 220 The tube member 100 is temporarily opened by the pressure of the water when the stormwater is introduced into the storm drain pipe 310 through the elastic fixture 200 provided therein, The tube member 100 is closed by its own weight due to the own weight of the load member 110 attached to the tube member 100 so that the odor flows back through the tube member 100 of the sewer pipe To prevent It is.

The above-described conventional malodor shielding apparatus has a disadvantage in that it is easily torn due to the simple manufacture of the tube member 100 made of vinyl material. Particularly, in case of rainy season, The tube member 100 is easily damaged due to its short service life, and the maintenance personnel need to periodically inspect and repair the tube member 100, which makes maintenance difficult.

In addition, the tube member 100 has a disadvantage in that it is easily lost if the elastic member 200 is fixedly secured to the elastic member 200 through the use of a velcro tape (commonly referred to as a squeak).

In addition, the elastic fixture 200 is easily deformed due to the material made of the steel material, so that even if the elastic fixture 200 is closely attached to the discharge pipe 310 at an early stage, the elastic fixture 200 is loosened and detached from the discharge pipe.
