Definitions

  • the invention relates to a method for relieving an in a path body built-in part of acting Powers.
  • the invention also relates to a shaft from several rings standing on top of each other in a path, those to limit one set up in the way body Construction pit are supported and directed towards a path surface taper on one side to an edge that can be closed by a manhole cover.
  • the object of the present invention is therefore the built-in part to be installed in the way body so that in its area forces occurring evenly in a surrounding the built-in part Can be initiated underground.
  • This method ensures that already above the An even distribution of the forces takes place, so that the built-in part is not a major one by these forces Share must take over as the entire environment.
  • This large-scale distribution of the occurring loads is achieved, that in the entire area of the large component Densification of the environment occurs evenly so that a punctual break-in of highly stressed parts is avoided.
  • the built-in part therefore remains uniform within one compacted environment in its installation position without a selective distribution of stress on individual parts of the environment give way and thereby to a collapse of the whole Lead building.
  • the invention relates to a shaft made of several rings standing on top of each other in a path body a boundary of an excavation pit set up in the road body are supported and towards a path surface taper conically on one side to an edge that extends from a Manhole cover is lockable.
  • the task is solved by that in the area of the edge a force from the road surface receiving and on a surface adjacent to the edge distributing plate is provided on a Shaft surrounding layer is supported.
  • Such a plate has the advantage that it is in one hand is able to force the forces evenly into the environment derive the shaft and on the other hand because of their heavy weight to dampen vibrations. she can be laid easily and with the desired accuracy that they will bring the benefits they expect can.
  • a plate designed as a foundation plate with its Middle opening over a surrounding the opening of a shaft Edge pushed until the plate is just above an upper one
  • the boundary of the edge runs with its surface.
  • the foundation plate is supported on an adhesive layer, entered into a construction pit surrounding the shaft becomes.
  • the foundation slab is shortly after entering the adhesive layer, in particular a concrete layer, in these are embedded so that they are completely free from the curing
  • Adhesive layer is supported.
  • This intimate connection forms between the adhesive layer and the foundation plate this with the adhesive layer and one with the substrate bonded very resistant layer that has a high moment of inertia owns. Because of this high moment of inertia it dampens those introduced into the foundation plate from above Vibrations so strong that they are below the adhesive layer barely noticeable. Also distributed the large one lying on a slope of the shaft top Concrete layer the forces introduced into it on a large part of the slope.
  • Embedding the foundation slab can also be in a layer of gravel, granules, recycling material or from an elastic mass.
  • the foundation plate is largely in terms of its size adapted to the cross section of the excavation pit, for the renovation of the shaft is needed.
  • the foundation slab enabled those introduced into it Forces largely evenly over a comparatively large one Area into the underground, so that per unit area only comparatively small forces in the adhesive layer and thus be passed on underground.
  • This base plate has two functions, which consist of the one above the edge fill existing space even with large construction pits and on the other hand, due to a large mass, the vibrations that occur dampen before they can enter the shaft.
  • the base plate is made relatively thick, so that they are straight with usual means of transportation can still be moved. This heavy training of the base plate leads to this either together with the foundation plate or even without this a very damping Have function against the vibration loads that caused by passing vehicles and kept from the shaft Need to become.
  • the base plate also surpasses that Edge of the shaft, but is largely on a foundation surrounding the shaft. In this way comes a distribution of those introduced into the base plate Forces come about, so that the foundation and possibly also an existing foundation plate can be relieved.
  • the initiated Forces are in the shaft without endangering Derived underground.
  • the invention is at least one further plate above the base plate arranged for height compensation.
  • Support rings are used for this, which are also made in a rectangular shape, so that they are as large as possible on the one below them Rest the base plate. On the one hand, they have a smaller one Wall thickness than the base plate and thus also a smaller one Weight. You will be advantageous to filling out an above the base plate in some cases up to the surface of the Wege stressess existing space used, so that the of forces introduced above can be transferred well. To this way, the support rings contribute to an efficient construction at, which is geared to the loads occurring effectively by passing vehicles from the shaft keep away.
  • This elastic liner is designed in such a way that it can withstand significant vibrational loads Can take into account that of passing vehicles Vehicles are generated. For example, with trucks with four axles, the shafts at least four sometimes subjected to pressure and then relieved. there remains unconsidered that the suspension on uneven roads the vehicles generates further vibrations and via the Tires in the road body transfers. Hence will clearly that the vibration exposure of the road body dampening measures may be required due to high static weights alone not overcome can be. Therefore, between the individual parts of a shaft structure uses elastic materials that on the one hand are capable of transmitting high loads, but on the other hand, the vibrations transmitted by the shaft structure to dampen.
  • the elastic intermediate layers with the plates and / or Support rings firmly connected.
  • Such intermediate layers are either integrated into the plates and / or support rings or attached to their surfaces. In any case, they are enough to reduce the vibration loads that occur.
  • the elastic liners over each other applied area. Get this way they have a large force-transmitting surface so that they are suitable are to transfer the forces without prematurely yourself To take damage.
  • the elastic intermediate layers are only partially on the Surfaces of the plates and / or support rings applied.
  • This partial application has the advantage that in this way Vibration behavior of the plates and / or rings is best influenced can be.
  • these are comparatively narrow intermediate layers under a high dynamic load, so that they must be expected to wear out quickly.
  • the individual Parts of the shaft structure aligned so that they like a coherent building with a high damping effect Act.
  • the foundation plate has an opening receiving the edge on.
  • the foundation plate surrounds with your Open the entire top of the shaft so that this supported on all sides and thus relieved.
  • the highly endangered edge is thus protected from damage protected.
  • the foundation plate is the same in the load-bearing capacity of a subsurface surrounding the shaft available. This surface can be used when setting and repairing the shaft not in all surrounding the shaft Areas are compressed evenly, as not all Areas with a vibrator are equally easy to reach. In particular the vibrator in the area of the cone can only be very restrained be used.
  • the foundation slab overhangs the edge by a protective distance. This measure primarily creates the foundation slab used in the transmission of the occurring forces, but not the edge of the shaft. This remains relieved.
  • the protruding part of the foundation plate can be very well used as a seat for an elastic ring on which the base plate is opposite one of the shaft boundaries Supporting surface supports.
  • the base plate corresponding to the opening of the shaft Recess provided.
  • the base plate therefore covers the Edge of the shaft, so that all loads from this be kept away.
  • the base plate distributes these forces evenly on the foundation and any existing one Foundation plate.
  • the stones on the support ring in an adhesive layer stored are the stones on the support ring in an adhesive layer stored. This design is used in particular if the distance between the edge of the shaft and the Road surface the laying of one or more support rings makes necessary. In this case, the stones in the adhesive layer on the adjacent support ring supported.
