Description

The invention relates to a method for refurbishing a Shaft with a shaft lining made of plastic.

Moreover, the invention relates to a device for rehabilitation a pit in which at least one sewer opens, with a plastic shaft lining.

Mines including the sewer drains entering into them represent a significant environmental problem. For this Basically, an extensive program for the rehabilitation of Pit facilities launched. This program will be in the next Decade to a comprehensive renovation and modernization the entire sewage system and in particular the pits to lead.

There are a lot of remedial measures in the past been tested. These were very expensive on the one hand and on the other hand also time consuming. So were dilapidated Pit plants that meet the requirement for leak-proofing and invading water did not do it often completely rebuilt. In view of the extensive earthworks and the installation of new pits is this procedure very expensive and therefore not suitable for large-scale use in the area-wide rehabilitation of sewage systems.

In addition, it was found that masonry and concrete Pit to meet the high tightness requirements are not up to it. Made in this way Shaft walls are open-pored and allow both Discharge of wastewater as well as entry of groundwater. An open-pore material is therefore for the production of Pit facilities not suitable. Later on the shaft wall Applied sealing material carries the high continuous loads usually not enough bill.

On the other hand, from the standpoint of tightness, the Use of manhole liners made of plastic material proven. This permanently prevents the passage of water both out of the shaft and into the shaft. However, there have been difficulties that consisting of plastic sheets manhole liners within the shaft only with difficulty and with large ones Effort could be aligned. There were solutions known that lead to a seal of the shaft bottom and possibilities should provide a watertight connection with the manhole lining. For this purpose deep-drawn floors were used, already in the manufacturer Gullies were incorporated through which the water should be passed through the shaft. This floor construction But they were not only expensive to produce but especially when laying. In particular, showed almost insurmountable difficulties in the ground furnished ground gutter with that of sewers connected sewage system. Appropriate Attempts to exclude the gutters to the sewers, presupposed expensive directional systems, which are rare Satisfied the high demands on tightness against wastewater. They therefore arranged the existing manhole constructions only incomplete under, so that elaborate reconstruction measures had to be performed before the prefabricated floors could be used. He was threatened by these difficulties Thought of shaft failures failing with the help of prefabricated manhole liners should be made.

The object of the present invention is therefore a method and to provide a device by means of which a more appropriate Installation of manhole liners is made possible.

This object is achieved in terms of the method thereby that the mine with respect to at least one sewer is adjusted and the manhole lining re through the pit extending portion of the sewer aligned and connected to it.

The passage of a sewer through a mine is already known, but without that on this The resulting channels as a basis for the entire lining of the shaft is used. The knowledge of the fundamental Meaning of the channel formed in the area of the mine for the absorption and release of water and as an element the adjustment of the entire pit to prevent Movements, for example, by floating and as a basis for a static alignment of the necessary installations for Sealing of the shaft interior relative to the surrounding Soil was recognized later and eventually led to Subject of the invention described herein.

By aligning the manhole lining with respect to the sewer The shaft lining became a solid foundation which, over time, also through aging the corresponding materials are not subject to fluctuations is. At the same time, the orientation of the shaft lining led Regarding the sewer also changes in the assignment between the manhole lining on the one hand and the shaft are excluded on the other hand.

A shaft system (2) embedded in a road surface (1) consists essentially of a shaft wall (3) and a Shaft bottom (4). The shaft wall (3) surrounds an interior space (5) facing towards the road surface (1) of a Opening (6) is completed. On the shaft wall (3) is in the direction of the interior (5) a steel fabric (7) attached. In addition, protrudes into the shaft wall (3) a dowel (8) into it.

At a distance (9) of about 10 cm is with the shaft wall (3) a manhole lining (10) connected concentrically to a surface (11) of the shaft wall (3). there is assumed that the mine (2) a has circular cross-section.

The shaft wall (3) is usually made of masonry Stones or concrete. In any case, it can be assumed that that the shaft wall (3) is open-pored, so that approximately on an outer side (12) of the shaft wall (3) accumulating groundwater through the shaft wall (3) can get into the distance (9). This can be in the Distance (9) form a water column, which is suitable, the Manhole lining (10) in the direction of the interior (5) deform. To prevent such deformation, the Shaft lining (10) connected to the shaft wall (3), for example by means of the dowel (8) or by an attachment on steel mesh (7).

The shaft lining (10) consists of a water-impermeable Plastic, for example polyethylene. These Manhole lining (10) is in the form of a deformable plastic web into the interior (5) brought in and then with respect the shaft wall (3) aligned so that between the manhole lining (10) and the shaft wall (3) over the entire height of the mine (2) and over its entire length Cross section of the distance (9) is about the same size.

In a lower part (13) facing the shaft bottom (4) the pit (2) are in the shaft wall (3) holes (14), (15) provided, through which a channel (16) with their raw-shaped ends (17), (18) in the direction of sewers (19), (20). Through these sewers (19), (20) wastewater is on the one hand towards the mine (2) and on the other hand from this further towards, for example transported a treatment plant, not shown. The raw-shaped ends (17), (18) are designed in this way, that they are in one of the sewer (19), (20) enclosed Interior (21), (22) can protrude and opposite this sealed by means of seals (23), (24), (25) are. These three seals (23), (24), (25) lie in Longitudinal direction of the channel (16) on its raw-shaped ends (17), (18) in a row.

In the area of the interior (5) has the channel (16) only a partial cross-section (26), in whose area they are a in Direction to the opening (6) open top (27). In the area of this open top (27) is the gutter (16) and via this also the sewer (19), (20) accessible from the outside, for example, to clean and control the sewer (19), (20). In addition, in the field of open shell (27) wastewater from the interior (5) in the Get gutter (16) and transported into the sewer (19), (20) become.

The gutter (16) consists of two gutter sections (28), (29). Each of these two sections (28), (29) protrudes with the respective tubular ends (17), (18) in the respectively adjacent Sewer (19), (20) into it. This will be the gutter sections (28), (29) aligned so that they are with each other collide adjacent ends (39), (31) in the interior (5). In this position, the two ends (30), (31) connected by a weld (32).
