Definitions

  • the present invention relates to a method for renovating wells, especially drain wells.
  • Old drain wells made of concrete rings tend to become untight in the course of time partly because the rings located above the frost limit lift out of position when the frost is beaking up, and partly as a result of corrosi ⁇ on.
  • the concrete rings and pipes used in old drain pipe systems corrode at an ever-increasing rate for example as a result of the increasing use of strong detergents.
  • Suita ⁇ ble materials for the ring elements include polyurethane, polyester, epoxy, polyethene, polypropylene, light concre- te, etc.
  • Fig. 1 shows schematically in section a sideview of a well renovated according to this invention
  • Fig. 2 shows an example of a ring element according to the invention, seen from above.
  • the object of the invention is to renovate old wells, especially wells made of concrete rings 1, which wells have become untight as a result of corrosion or mutual movement of the concrete rings 1.
  • the renovation is performed so that semi-circular ring elements 3 with a smaller diameter than the inner diameter of the original well are led into the old well through an opening 2.
  • the advantage of using semi-circular ring elements 3 is that they can be led simply into the well through the conventional opening 2 without having to remove any concrete covers.
  • the first pair of ring elements 3 is placed concentrically on the bottom of the old well and joined together e.g. by rive- ting. The eventual gap between the bottom and the ring elements 3 is then tightened in a suitable manner.
  • the next pair of ring elements 3 is placed above the first pair of ring elements 3 and joined together.
  • the ring elements 3 placed on top of each other are kept in position by conven- tional, co-acting joint grooves 4 along the upper and lower edge of the ring elements 3.
  • the ring elements 3 located on top of each other are placed so that they overlap each other, whereby the vertical seams 5 between the respective pair of ring elements 3 are located on different planes.
  • the joint grooves 4 then affect such that they keep each pair of ring elements 3 together.
  • the best possible strength is obtained, if the ring elements 3 on two layers on top of each other are turned 90° in relation to each other.
  • the gap between the old well rings 1 and the ring elements 3 is filled with concrete 6, whereby a completely tight and corrosion resistant well is obtained, which is not affected by frost either.
  • the ring elements 3 are preferably made of polyurethane, polyester, epoxy, polyethene, polypropylene, light concrete or the like by casting in a closed form or by centrifugal casting. According to a preferred embodiment, the form is filled only partially with a plastic mass containing an expansion medium, which mixture after the expansion fills the entire form. A suitable foaming degree is obtained, when a ring element 3 of polyurethane has a density of ca. 0.2 - 0.6 cm 3 .
  • the main part of the ring elements 3 forms during the joining a cylinder, but the uppermost pair of ring elements 3a can preferably have a form, which results in a trunca- ted, eventually slanting cone, especially, if the old concrete well is built with a corresponding form.
  • the polyurethane ring elements 3 preferably have a height, which is slightly smaller than the height of the concrete rings 1.

Abstract

Cette invention concerne un procédé de rénovation de puits, plus particulièrement destiné aux puits de drainage. Elle se caractérise par le fait que des éléments annulaires semi-circulaires (3, 3a) d'un diamètre inférieur au diamètre intérieur du puits d'origine sont introduits dans le vieux puits, à travers une ouverture (2), lesdits éléments annulaires (3, 3a) étant empilés de manière concentrique et par paires les uns au-dessus des autres dans le puits jusqu'à une hauteur voulue, après quoi, l'espace existant entre les anneaux du vieux puits (1) et les nouveaux éléments annulaires (3, 3a) est rempli de béton (6).
