Abstract

PURPOSE: A manhole grating is provided to prevent the accumulation of foreign materials because foreign material blocking covers are formed as two end grates and end bars are angled. CONSTITUTION: A manhole grating comprises foreign material blocking covers which are formed on two sides and end bars which are formed at an angle on the other sides. The bent lower parts of the ends bars are cut to insert and weld manhole grating I-bars(6). Reinforcing steel plates(7) are installed on the rear sides of the lower parts of the end plates.

Description

Foreign body blocking manhole grating {omitted}

The present invention relates to a manhole grating, which is a drain cover, to drop foreign materials installed in the automatic closure switch of a foreign material installed at the bottom of the manhole with the foreign material blocking cover (2) and the end bar (4) on each side of the manhole so that foreign matter does not stop in the manhole grating. It is possible to collect and reinforce with a reinforcing steel plate at the bottom rear of the inclined structure of the end bar is a stronger manhole grating.

At present, the structure covered by the manhole grating has a disadvantage in that foreign matter accumulation is exposed as it is, and the present invention is also capable of saving raw materials by strengthening the end bar in the construction of the manhole. Therefore, in recent years, because the odor breaker is installed at the bottom of the manhole grading, foreign matter is more accumulated around the manhole. In this way, the front and rear end bar inclination and one space on both sides of the manhole grating prevents the foreign material from stopping by the foreign material blocking cover, so that the foreign material is dropped into the automatic switchgear, concealed, and collected.

Therefore, the present invention prevents foreign matters from accumulating in the end bar 4 and manhole grating both sides with a foreign matter blocking cover 2 on both sides of the manhole grating. It is.

The manhole grating according to the present invention reinforces the reinforcing steel plate 7 at the bottom of the rear lower and lower portions of the back and rear of the manhole grating front and rear end bar 4 to insert the eye bar 6 so that dirt and foreign substances do not stop and fall into the sewer. It is characterized by the configuration of the C-shaped steel, which prevents the circular damage of the furnace and foreign matter blocking cover (2) on both sides of the manhole grating.

As described above, the present invention is that the manhole grating foreign matters do not accumulate and the foreign matter falls to the automatic automatic switchgear so that the manhole grating is always clean.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 7, the structure of the present invention is filed on the basis of a manhole grating housing 1 currently installed on the market. Existing manhole gratings are installed with odor breakers at the bottom of the manholes, where foreign matters are concealed in the center, and clean, but foreign matters are accumulated around the manhole gratings and dirt is accumulated on each side. Thus, in the present invention, the reinforcing steel plate 7 is exposed to the lower end of the rear surface of the back of the eyebar 6 after assembly welding where the manhole grading eyebar 6 is inserted into the blue bottom to bend the end bar 4 of the front and rear inclined. The manhole grating is reinforced up and down to prevent circular breakage, which is stronger, and each compartment on each side is composed of a foreign material blocking cover (2) and a C-shaped steel, which is stronger and does not accumulate foreign matter at all. (Here, foreign matter of manhole grating on both sides The reason for constructing the blocking cover 2 is that if the foreign matter blocking cover 2 is not configured, the housing 1 of the manhole grating is wider than the sewer so that one space on both sides is blocked by the foreign matter blocking cover 2 so that the foreign matters fall into the sewer. After the installation of the automatic switchgear, the foreign substance at the bottom of the manhole grating can be used to block odor and prevent backwater. It is clean.

Claims

Reinforced steel plate on the exposed side of the lower end of the end bar 4 after assembling and welding by inserting the eye bar 6 into the lower end of the manhole grating on both sides of the foreign matter blocking cover 2 and the end bar 4 of the front and rear sides. 7) Stronger foreign material blocking manhole grating to prevent damage to the circle by reinforcing.
