Definitions

  • the invention relates to a set of equipment of a locking system for a manhole structure that can be closed with a manhole cover.
  • the invention also relates to a manhole structure, in particular a sewer manhole, which can be closed with a manhole cover and has at least one partial volume that can be separated from the rest of the manhole volume and closed with a closure system.
  • the present invention also relates to a method for rehabilitation of a shaft structure and the use of a locking system for rehabilitation and / or production of a shaft structure.
  • Shaft structures are essential components of public and private infrastructure facilities. It is only through shaft structures that infrastructure lines running underground, such as Laying sewage, water, electricity or telecommunication lines over longer distances, connecting them to one another in network structures, maintaining them and, if necessary, replacing them.
  • Shaft structures typically have a cavity that is present in the subsurface or is embedded in another structure, which is accessible through an opening and can be closed on the surface with a manhole closure or manhole cover.
  • Infrastructure lines of the respective infrastructure facilities for example pipelines, channels, gutters and / or cables, then open into the cavity of the shaft structure and / or are passed through it. This makes it possible to merge infrastructure lines in the shaft structure, to cut them, to change direction or to bridge the height. Also Infrastructure lines in or through the shaft structure can be checked, maintained and / or cleaned.
  • Older sewer networks which are based on mixed systems, are typically renovated in such a way that the existing manhole structure is only used for the sewage network, while an additional manhole structure is built for the rainwater sewer network - or vice versa.
  • this increases the space requirement when renovating older sewer networks in the area of the shaft structures strong. This is particularly problematic in locations with limited underground space, for example in urban areas with a high density of underground infrastructure facilities or in the area of the track systems of trams and trains, which are sensitive with regard to ground movements.
  • the object of the invention is therefore to provide advantageous devices and / or methods with which manhole structures for infrastructure facilities can be constructed or renovated in a manner that saves space, is inexpensive and / or simple. This especially in connection with infrastructure facilities in which several and different infrastructure lines have to be run separately from one another.
  • corresponding devices and methods for sewage systems with separate sewer networks for waste water and rainwater are to be provided.
  • the solution to the problem with regard to the device is defined by the features of independent claim 1.
  • the features of independent claim 18 define the solution with regard to the method.
  • manhole structures can be realized in which two or more infrastructure lines running through a manhole structure can be separated from one another in a liquid-tight manner in the same manhole structure.
  • a partial volume that can be separated from the rest of the shaft volume can be implemented in an already existing shaft structure or in a new shaft structure that can then be opened or closed with the closure according to the invention.
  • the closure is locked with the locking unit, the separable partial volume and the remaining partial volume are completely separated from one another. If the locking unit is in the release position and the lock is opened, there is, on the other hand, access to the separable partial volume from the remaining partial volume. If necessary, e.g. For maintenance work, access to the individual infrastructure lines is possible through a single shaft structure with a single shaft cover, while in normal operation the infrastructure lines are routed completely separated from one another through the same shaft structure.
  • the locking unit for the manhole cover and its coupling to the locking unit ensures that the manhole structure is only locked correctly and completely Closure can be closed. This ensures that the separable partial volume and the remaining shaft volume are safely separated from one another when the shaft cover is closed. Incorrect manipulation is almost impossible.
  • a single shaft structure can be used to implement a system which enables different infrastructure lines to be separated just as reliably and safely as a conventional separation system in which the access to the infrastructure lines is implemented via separate shaft structures.
  • the equipment set according to the invention thus makes it possible to renovate existing manhole systems with unchanged space requirements, so that they can be used for separation systems. Furthermore, new shaft systems can be designed directly for separation systems with the equipment set according to the invention. In both cases there is a significant cost reduction and space saving, the latter both in the subsurface and on the surface, where only a single manhole cover is necessary.
  • construction or renovation work can be considerably simplified when using the equipment set according to the invention.
  • significantly smaller and easier-to-operate construction sites are possible for construction or renovation work compared to conventional separation systems.
  • you can manage with significantly smaller trench profiles while in the case of renovation work or the conversion of an older mixed system to a separation system, the floor does not have to be opened at all, as the renovation can be carried out directly in the existing shaft.
  • the equipment set according to the invention is of particular interest for the renovation or construction of manhole structures for sewage infrastructure lines.

Since the first intermediate wall 331, seen from the left, has a recess which is complementary to the cross section of the bolt in the area of the cuboid projection, the bolt 310 in the FIG Fig. 3a rotational position shown are not moved in the axial direction to the left, since the cuboid projection 314 is present on the first partition 331. A movement in Fig. 3a to the right is also prevented by a guide pin 311 protruding in the radial direction from the bolt 310 with a spherical grip, which rests against the second partition 332.
  • a flange-like entrainment element 312 in the radial direction from the bolt 310.

  • the locking element 520a can be additionally supported in the locking position within the guide 510a by the projection 515a.
  • the groove 522a.1 lies directly on the complementary projection 515a, which also prevents the blocking element 520a from being in the horizontal direction when a large force is exerted on the free end 521a jumps out of the locked position and can be pushed down.
  • the locking element 520a is thus both hooked with the hook-shaped end section 521a at the upper end on the edge of the guide 510a and is supported on the inside on the projection 515a.
