  • pavement work can be performed continuously without interruption in the manhole. The construction efficiency can be increased, and the manhole does not become a protruding obstacle even if the road is temporarily opened during pavement construction, so that vehicles and passers-by can use the road safely.
  • Filler is filled into the fitting surface of the fitting body and the surrounding pavement.
  • the filler used is a pressure-sensitive adhesive that has an adhesion control layer consisting of a porous film, porous fabric, and porous paper in which a large number of circular holes and square holes are formed. When detached, it can be easily peeled off.

Since the position of the manhole is covered with pavement and cannot be determined, measure the distances from the multiple reference points at the road edge to the center of the manhole in advance and mark the pavement surface. If the mark cannot be found, use a metal detector or install a transmitter (not shown) on the temporary lid to detect the signal and obtain the position of the Manhorne.

Abstract

L'invention concerne un procédé de construction de trou d'homme sans couvercle en acier afin d'uniformiser la partie trou d'homme avec la chaussée. Le confort lors de la marche et la circulation des voitures s'en trouvent améliorés, ainsi que l'efficacité fonctionnelle de la construction de la chaussée. Ledit procédé consiste à créer une ouverture (3) en découpant et en enlevant la chaussée juste au-dessus du trou d'homme de forme conique, en ajustant à l'ouverture (3) un corps adapté (1) du même matériau que celui de la chaussée, et en remplissant avec un élément de remplissage les espaces entre le corps adapté et la chaussée de façon à former un couvercle. Ainsi, la surface de la chaussée et le corps adapté (1) s'intégrant l'un à l'autre, on élimine le sentiment d'inconfort dû au couvercle en acier, on augmente l'efficacité fonctionnelle, puisque l'opération de revêtement de la chaussé n'est pas interrompue à la partie trou d'homme, et on empêche la survenue de glissades sur le couvercle en acier.
