Definitions

  • the invention relates to sewerage articles, in particular manhole covers and street attachments, which consist of a frame embedded in the carriageway surface and an insert, in particular an inlet grate or a manhole cover.
  • plan-level processing of the two contact surfaces did not lead to the desired success.
  • the level support can be disturbed by warping or the ingress of dirt, which in turn leads to the tilting of the insert and finally to the abrasive wear of the contact surfaces.
  • a further improvement in the form of a damping insert made of elastomer integrated in at least one support surface does not bring a permanent solution to the problem in many cases. It has been shown that the damping insert incorporates the penetrating dirt, so to speak, and then has a sanding effect on the counter surface with this dirt. The result is also selective wear of the contact surface in the frame.
  • the depressions can be molded in and do not require any machining.
  • the depressions can have the shape of troughs or blind holes.
  • the covering is applied after the connection or filling. This can compensate for the distortion that may have occurred due to the setting of the concrete.
  • the contact surfaces are then absolutely flat.
