摘要:
The object of the invention is a container (1) especially for chemical substances consisting of a substance chamber (2) of tubular plastic film (10) and a funnel-shaped headpiece (3). The film consists of low-density and the headpiece of high-density plastic. The tubular plastic film (10) is secured in the headpiece (3) by pressing. The headpiece (3) may be divided into a plate-shaped (4) and a tubular (5) section. On the side towards the substance chamber, the plate-shaped section (4) has an annular groove. The plastic film (10) is pressed into place by a securing ring with a U-shaped cross-section which can be pressed into the annular groove. A snap mechanism holds the securing ring firmly in the groove. The tubular plastic film (10) is firmly pressed between the securing ring and the groove walls. The container (1) can be closed at the rear by a suitable closure device.

A robot for the repair of sewer pipes comprises a carriage unit driven by a traction motor (2) arranged internally of a carriage housing (1) with wheels (7,9). The carriage housing (1) is connected to a rotary head (15) arranged immediately before the carriage housing (1). The rotary head (15), having tools and/or inspection devices mounted thereon, is driven by rotary motor (22). The traction motor (2) and the rotary motor (22) are arranged in a mutually overlapping relationship. The rotary head (15) is connected to a hollow shaft (23) extending through the whole carriage housing (1). The rotary head (15) is adapted for attachment of a robot arm carrying a tool support. A swivel arm of the robot arm as well as the tool support can be swiveled by hydraulic cylinders. The end of the robot arm facing away from the rotary head (15) is provided with a support wheel.

The invention involves a device and a process which can be employed for sealing building branch lines (3b) leading from a building or a collecting manhole directly to a sewer main (4) using a relining process in which liners (1) made of self-hardening/self-curing sealant are used. In the process according to the invention, a pipe repairing machine (6) is employed which features a rope guiding device (10) at its front end (14), said rope guiding device (10) being comprised of a roller mount (15) to which a deflection pulley (5) and a retaining roller (16) are affixed. The pipe repairing machine (6) into whose rope guiding device (10) the rope (7) to which the liner (1) is attached is threaded is positioned inside the sewer main (4) at the building branch line junction (2) in such a manner that the rope (7) does not come into contact with the building branch line edge (9) facing the pipe repairing machine (6) when taut. While the rope (7) is being pulled through the building branch line (3b), a support foot (11) with a brake block (12) ensures that the pipe repairing machine (6) does not shift.

The new, remote-controlled installation of sheathing into inaccessible manifolds and junctions from subsidiary into main piping makes it possible to repair damaged intersections cheaply, rapidly and reliably, without the intersection having to be exposed by excavation. An application device (1), which is installed on a pipe-repairing machine, makes insertion of a lost sheathing (4) into the subsidiary piping (8) possible. The cavity (12) which comes about in this way between the sheathing (4) and the damaged part is subsequently sprayed with specially suited sealing mass by means of a high-pressure nozzle (13).

The invention in question is a repairing machine, which is suited to repairing damaged conduits which are inaccessible for repair work. This repairing machine is remote-controlled and monitored with television cameras. At the head of the driving carriage, various devices, which are necessary for the repairs, can be attached to a motor-driven rotatable toolhead. A simple construction of the movable head has made it possible to accomplish all of the necessary movements with uncomplicated mechanics, and at the same time, to forego a tedious slide coupling for the control lines without letting them get tangled with the device. Therefore, with this invention, the production costs for the whole device could be lowered and, likewise, the proneness to repairs could be reduced.

摘要:
This invention is a new method and at the same time a new piece of equipment for the renovation of damaged pipelines in which formation of fragments has come about or the pipelines have partly been completely destroyed. The machine can be fitted to a channel renovation robot or to a conventional luge and can be remote controlled with television support. With the machine, which has a simple locking mechanism (4), a metal sheathing (11) is inserted into the interior of the pipe. The sheathing is ejected there in order to repair a damaged point or a missing piece of pipe, whereupon a sealing mass is pressed onto the outside through holes in the sheathing.
