Definitions

  • the present invention relates to a separation-preventing device of a manhole cover, and more particularly, to a separation-preventing device of a manhole cover, which can prevent movement and separation of a manhole cover, thereby preventing cracks of a concrete road around the manhole buried in the ground.
  • a manhole is communicated with a water supply hole and a sewage ditch. So, when the water supply hole and the sewage ditch are clogged due to lots of sewage and a flood, manhole construction work is carried out for inspecting the inside of the manhole after a manhole cover is opened. Furthermore, the manhole construction work is also carried out every predetermined interval for electric wiring of cables or city gas construction. In addition, the manhole construction work is also carried out on the asphalt road. In this case, repairing work must be carried out for covering the asphalt road with Ascon (Asphalt concrete) or concrete again when the road surface is not even due to the first asphalt road construction work or aging of the asphalt road. At this time, the manhole construction work has to be carried out in such a way that the manhole formed in the road serves as an underground passage of a drainage system.
  • Ascon Ad
  • FIG. 1 shows a structure of a conventional manhole.
  • a manhole body 10 is located at a side of the underground passage communicating with the water supply hole and the sewage ditch.
  • the manhole body 10 includes a height- variable ring 20 seated on an upper opening part 11 and having retaining steps respectively formed on the upper and lower portions of the inner periphery of the height- variable ring 20.
  • a manhole cover 30 is placed on the upper retaining step of the height- variable ring 20.
  • the conventional manhole cover 30 is put in the manhole body 10 or the height- variable ring 20. Therefore, when heavy and large-sized trucks con- tinuously pass the top surface of the manhole cover 30, the manhole cover 30 is slightly moved from the seated portion between the manhole cover 30 and the manhole body 10. Particularly, in case of a small-sized manhole cover 30 which has a diameter of about 20cm, the outer circumference of the manhole cover 30 is worn away as long time goes by, and so, the manhole cover 30 is separated from the manhole body 10 due to the external instantaneous power and pressure. Since the conventional manhole cover 30 does not have any device for preventing separation from the manhole body, in case of the small-sized manhole cover 30, children can easily lift the manhole cover, and thereby, accidents may occur.

Abstract

L'invention concerne un appareil empêchant la séparation d'un couvercle de regard et comprenant: un corps de regard enterré dans le sol et présentant une partie creuse formée dans celui-ci; un anneau à hauteur variable monté sur le corps de regard et présentant un étrier de retenue formé sur la surface périphérique interne de celui-ci; un couvercle de regard disposé à l'intérieur de l'anneau à hauteur variable; et une partie empêchant la séparation permettant de fixer le couvercle de regard, ladite partie comprenant: un élément support disposé sur l'anneau à hauteur variable; et un élément de fixation connecté à l'élément support de manière à fixer la surface supérieure du couvercle de regard. Quand des camions lourds et aux dimensions importantes passent en continu sur la surface supérieure du couvercle du regard, l'appareil selon l'invention permet de minimiser le déplacement dudit couvercle, empêchant ainsi des craquelures de se former dans la route en béton asphaltique autour du regard enterré dans le sol.
