FALL PREVENTION DEVICE FOR MANHOLE
The present invention relates to a manhole. Specifically, according to the present invention, in a manhole main body, chemical anchor nuts are installed at equal intervals on the lower part inner periphery spaced apart from a manhole frame so as not to interfere with the manhole frame. In addition, after a fall prevention grating is inserted, an anchor bolt is fastened to the chemical anchor nut so that the fall prevention grating is firmly and tightly fixed to the manhole main body. Therefore, damage to a connection part due to shaking, and so on is prevented. A fall preventing apparatus for the manhole of the present invention comprises: a manhole main body; a manhole bracket; a manhole cover; the fall prevention grating; and an odor blocking film.
본 발명은 맨홀에 관한 것으로서, 상세하게는 맨홀 본체에서 맨홀 프레임과 미간섭되도록 맨홀 프레임과 이격된 하부 내주연에 등간격으로 케미컬 앵커 너트를 설치하고, 추락 방지 그레이팅을 삽입한 다음 케미컬 앵커 너트에 앵커 볼트를 체결하여 추락 방지 그레이팅이 맨홀 본체에 견고하게 밀착 고정되도록 함으로써 흔들림 등에 의해 연결 부위가 파손되는 것을 미연에 방지하도록 하는 맨홀용 추락 방지 장치에 관한 것이다.
