DE102006046813A1 - Cover section for supply or discharge line, has circular elastomer ring arranged behind cap-type sprocket and receiving forces from working loads, and resins allowing pipes hardening to produce statically supporting construction - Google Patents

Abstract

The section has a cap-type sprocket (1a) that is provided with a rubber or rubber-like elastomer mixture (3), where the section is made of rubber-or rubber-like materials e.g. elastomers. The materials are connected with fibers or felt portions in an operating process. Appropriate resins are applied on a carrier material and allow hardening of small pipes by appropriate hardening process, such that the section produces a statically supporting construction. A circular elastomer ring (7) is arranged behind the sprocket and receives forces from working loads. An independent claim is also included for a method of attaching profiles from elastomer in sewers by vulcanization robots.

Description

The The invention relates to a method for producing a hat profile made of rubber or rubber-like Substances used in combination with e.g. Fibers or fiber-like Materials supplemented which are used for the rehabilitation of house connections in sewers can be used. Another embodiment of the invention consists of vulcanised rubber in or at the service connection duct or rubber-like Materials directly on the site of repair of suitable machines 8sanierungsrobotern) be introduced.

hat profiles for the rehabilitation of house connection lines are already some Years in use. The current state of the art is detailed in ICT commodity test "renovation of house connection spigot Test 06/2004 and 11/2004 described.

One Hat profiles for house connection renovation is a renovation process to improve the current functionality of an existing domestic connection line to the main channel. Here is a flexible short tube made of carrier material soaked in a reaction resin and i.d.R. over a Robot device introduced into the house connection to be renovated.

There is the so-called hat profile with water or air pressure form-fitting of Robot pressed against the pipe wall of the old pipe. By the subsequent hardening of the Reaction resin creates a new sleeve-free and fabric-reinforced plastic short tube in the existing house connection line. Hat profiles have in the Usually a three-layer wall construction. Seen from the inside out, you meet first on an inner film made of PEHD or PU. It prevents contact during curing with the robot arm and forms the pipe inner wall after installation. Behind it is the so-called composite; a combination of cured resin system, support material and / or reinforcement. The last layer or the pipe outer wall may possibly be UP resin Liners formed by an outer film become. She should be a possible Leakage of excess resin prevent.

The support materials the hat profiles are processed into short-sleeved with a hat wreath and form after impregnation with the respective resin systems the complete hat profile as a short tube. The carrier materials can essentially be divided into two groups: synthetic fibers (needle felt) and glass fiber fabrics (eg corrosion-resistant E-CR glass) The substrates have to with Resin as possible Completely imbued become (impregnation). The curing of the resin is predominantly through thermal initiators such as e.g. Hardening with steam or warm Water performed. But also a light curing over Fotoinitatoren is possible.

One Disadvantage of all the above systems is the fact that the resin-impregnated Hat profiles represent a rigid system and a hinged connection to the main channel not possible is. This leads often to further damage on the already renovated service line, as natural movements from the underground as a result of traffic loads or subsidence in the ground can not be absorbed by these rigid systems.

Of the Invention is based on the object to eliminate the aforementioned disadvantages, in which a system is created, which is a renovation of the service line via a absolutely dense and articulated hat profile made of rubber and / or rubber fiber composites allows.

This is characterized according to the invention solved, that in the elastomer mixture viewed from the inside if necessary with a Fitted with foil can be and represents the pipe inner wall, by interference of fibers a carrier material for the Outside lying fiber fabric skin, which for mounting the hat profile impregnated with resin is fixed and according to the known curing process.

In order to the hat profile at the approach of the main channel to the house connection channel one articulated connection receives is a circumferential elastomer ring located just behind the hat cap. This serves primarily to the occurring forces, e.g. from traffic loads or subsidence, so that a demolition of the rehabilitated Hat profiles and thus leaks consisting of infiltrations avoided by groundwater or Exfiltrationen contaminated wastewater become.

An embodiment is in 1 and 2 shown.

This shows 1 the hat profile according to the invention ( 1 ) with hat-wreath ( 1a ), which of the pipe inner wall ( 2 ) viewed with a rubber or rubber-like elastomer mixture ( 3 ) is provided in or on the skin of suitable fibers ( 4 ) are integrated, which outwardly the known Fasergewebehaut ( 5 ) form. This fiber fabric skin ( 5 ) is used for mounting the hat profile with suitable resins ( 6 ) and according to the known Curing process fixed. As circumferential breaking point and simultaneous hinged connection is a reinforced elastomer ring ( 7 ) attached to the hat profile.

2 shows the main channel ( 8th ) on which the hat profile ( 1 ) in the house connection channel ( 9 ) is integrated. The elastomer mixture ( 3 ) represents in this case possibly in combination with a film, the newly renovated pipe inner wall. To the outside to the leaky house connection channel ( 9 ), the carrier skin connected to the elastomer mixture forms fibers ( 4 ) the new tube outer wall.

A Further redevelopment can be achieved by mechanical vulcanization be made of rubber applied at the point of damage, the house connection to be rehabilitated in or on (for example by vulcanizing robots) he follows. Here, the raw material on the known vulcanization introduced at the refurbishment and cured. The resulting rubber body is in shape and size the damage feature adapted and can appropriate movements at the rehabilitation center take up.
