Description

The invention relates to a mobile enclosure with a stud frame with a fairing, for temporarily secured areas, namely for non-traffic tunnel cross sections in the context of the renovation or the construction of tunnels.

The need to refurbish and upgrade existing tunnels is immense throughout the world. Regardless of whether it is a tunnel used by motor vehicles or trains, in the context of renovation and expansion it is only necessary to impair traffic to the necessary extent. Usually, these construction measures are accompanied by a reduction to the still to be used tunnel cross-section. In the railway sector, this means that there is often a reduction from a two-way to a single-track route, so that there is sufficient space for the construction work around the single-track tunnel cross section remaining for further use. It is important to einhausen the remaining tunnel cross-section, so on the one hand prevents passing trains z. B. can collide with construction equipment and on the other hand passing trains and tracks z. B. are protected against stone chipping. This portal-like housings are formed by a stud, which is provided with a corresponding panel, suitably made of sheet metal. From the DE-OS 38 35 459 a device for re-cutting a tunnel profile is known. For this purpose, a machine which carries on a chassis a milling device, which is provided with a pivotable in height cutting arm. The cutting arm is installed in the cutting arm bearing on a support, which in turn is mounted in a Fußlager on a lifting member. The entire milling device is mounted on a carriage assembly consisting of a longitudinal and a cross slide exists. In addition to the re-cutting of a tunnel profile, a number of different tasks are involved in tunnel rehabilitation and tunnel construction. These are z. As the securing of the old tunnel vault leading by means of anchoring, the drilling of blasting holes and their occupancy for the blowing out of the extension ring, the later securing this extension by shotcrete and possibly anchor and the loading and the removal of the mountains. All of the above work must be accomplished with massive building equipment around the mentioned portal-like enclosure around. For reasons of space alone, various jobs such as anchor securing, blasting, loading and transport can not be performed during locomotive operation. From the JP-1 0-252-376 is a mobile enclosure for non-traffic tunnel cross sections in the context of the renovation or the construction of tunnels known. The enclosure includes a movable work frame. For the process of a propulsion aggregate, however, the entire work frame must be moved in the axial direction with respect to the housing, which leads to a very cumbersome, heavy and costly solution. This is especially true in view of the extremely cramped conditions in a tunnel renovation, just in the gap between the inner wall of the tunnel and the working frame with the various units. An individual or even unscheduled use of these units is thus virtually impossible, because always the massive work framework must be set in motion as a whole. From the DE 31 30 568 is a track device known, which is designed as a stable hood. This hood is adapted to the cross section of the deformed track area and extends far into the deformed area as well as into the already built-through area. This track-laying device serves as the basis for a cap lifter for the installation of expansion arches, which are guyed between the track sill and ridge. The contour of this device is therefore oriented to the expansion arches. Such a device is not suitable as a mobile enclosure in connection with tunnel cross sections which are not subject to traffic during the rehabilitation or expansion of these tunnels.

Thus, the present invention has the object to provide a device for the rehabilitation and expansion of tunnels, in which a variety of work can be performed even with continued driving.

This object is achieved in that the housing is designed as a support frame for receiving serving for propulsion units, wherein the outside of the housing is equipped with a plurality of parallel arranged in the axial direction of the rail pairs for moveable receiving ever an aggregate.

The enclosure thus fulfills its original purpose of protecting the vehicle, e.g. a train provided residual tunnel cross-section addition, another function as a base and support frame for various propulsion units serving, z. As shotcrete manipulator, drilling and Ankersetz- or charger.

A particularly robust embodiment provides that the outer side of the housing is equipped with rails for moving the units in order to be able to use different devices, possibly also simultaneously. Thus, a mobility of the aggregates or their simultaneous use is independent of the movement of the housing itself possible.

To achieve the greatest possible margin in terms of the longitudinal axis direction of the housing, it is proposed that rails are arranged in the axial direction. These can extend between both ends of the enclosure, so the reach is maximum.

Additionally or alternatively, it is provided that rails are arranged in the radial direction. These should extend at least over the upper half of the enclosure. An angle of approximately 180 ° for accordingly round trained, bow-shaped rails in the radial direction is considered sufficient to be able to process all areas of the tunnel surrounding the tunnel cross-section with the appropriate equipment can.

With regard to the running in the axial and radial directions rails is thought that a plurality of parallel rail pairs are provided in order to ensure the use of multiple equipment at the same time and independently.

A particular embodiment of the invention provides that the rails are part of a displaceably arranged bridge. On the bridge, the equipment can be moved in the radial direction, the bridge itself is movable in the axial, ie in the longitudinal axis direction of the housing. Thus, one and the same device can be moved both in the axial and in the radial direction, so that the entire tunnel cross section can be reached and processed around the enclosure.

It is envisaged that serves as aggregate at least one drilling or anchoring device. This unit should expediently be arranged in the front region of the portal-like enclosure in order to carry out the first work as seen from the outlet, namely the drilling and setting of blasting holes or the anchoring for additional protection of the mountains.

In addition, it is provided that the aggregate is a charger, preferably a conveyor, which is also integrated in the portal-like enclosure. Hereby the immediate removal of the mountains can be realized.

In a preferred embodiment, it is provided that the conveyor is designed as an inclined conveyor with a loading apron. The bulk material can be promoted in this way on the feederhouse in a vehicle, to then be transported away.

In this sense, the proposal is to be understood that the inclined conveyor is arranged sufficient space for a transport vehicle leaving. The discharge of the feeder must therefore be positioned at the appropriate height so that the trucks can be loaded there with the bulk material. The use of a monorail conveyor with corresponding transport containers would be conceivable here.

To secure the construction site contributes significantly if used as aggregate at least one shotcrete manipulator. This should be conveniently located in the rear of the enclosure to provide immediate backup of the remaining expansion after demolition.

It is also thought that the aggregate is a hydraulic hammer, a stone cutter or a cutting head. These are provided for processing the rock in the context of cross-sectional widening and tunnel rehabilitation and should also be arranged on the housing movable in the longitudinal and / or transverse direction expediently.

Another proposal aims to serve as an aggregate work platform, which is also integrated into the housing and arranged on this adjustable. The adjustability may relate on the one hand to a mobility on the rails and on the other hand additionally or alternatively to an adjustability by telescoping.

A particularly suitable variant provides that the working platform has foldable trained work surfaces. For this purpose, there are correspondingly pivotally mounted work surfaces on the outer sides of the enclosure, which can be swung up or down in case of need, to be able to work in the tunnel cross section as large a space as possible. If, on the other hand, there is only a small space requirement during transport or in case that other units are in use, these work platforms can be folded.

It has already been pointed out that the central work involved in the construction and rehabilitation of tunnels is the drilling and filling of the blast holes and the subsequent protection of the expansion by shotcrete. Therefore, it is expedient if drilling and anchoring device and shotcrete manipulator are provided in the direction of advance one behind the other on the housing. This ultimately makes it possible at the same time to make holes or anchor on the one hand and on the other hand at the other, the rear end of the enclosure with shotcrete to secure the expansion and this during the railway operations.

A further embodiment of the invention provides that the housing is equipped with a movable carriage, which carries a quick-change device. With the latter, the various units are compatible, so that a quick replacement and then the immediate commissioning is possible.

It is important to maintain the railway operation as far as possible in an unrestricted way. Therefore, it is considered appropriate if the housing is also equipped with a contact wire or a busbar. Catenary or busbar, mobile stored, serve as a catenary for electric locomotives and should therefore be positioned as possible below the housing ensuring the mobility of the units so that they are protected from damage and water. The enclosure can be moved independently of the contact wire or the busbar.

Additional possibilities arise when the housing is formed by at least two decoupled parts. Depending on requirements, these two or more parts form a unit in the sense described above or the parts are used separately, with the relevant aggregates on be coordinated with the respective application. As a result, additional flexibility for the use of various aggregates can be achieved.

It is provided that, for example, a part of the housing is designed as a support frame for receiving the units serving for propulsion and a part of the housing as a protective device. The two parts form either the addressed unit in the sense described above, or the trained purely as a protection part of the enclosure is separated from the other, the units receiving, part used.

In addition, it is thought that the protection device is adjustable in height. Cylinders thereby ensure e.g. the height adjustment and, if necessary, adaptation to the respective vault and also to its support. A multi-part and / or movable protective roof is also practicable.

Therefore, it is expedient if the protective device is installed on the housing movable. Again, the mentioned rails can serve as a basis for this.

In addition, it is provided that a part of the housing is designed as an installation portal for the tunnel lining. Here, for example, installation portals for concrete elements such as segments intended for the expansion of the tunnel cladding. The same applies to systems for tunnel sealing such as e.g. Geomembranes. This part of the enclosure can be designed separately movable and equipped with appropriate rail sections for the mobility of the actual installation device.

In order to ensure a safe and reliable dedusting of the work area, it is also provided that in conjunction with a suction port, the housing is equipped with an inflatable tube to seal the old tunnel. This bridges the gap between the enclosure forming the portal and the old tunnel.

The invention is characterized in particular by the fact that a mobile housing for use in the context of the renovation or the construction of tunnels is created with the faster and safer than before various finishing work can be performed simultaneously. While the remaining for the motor vehicle or train tunnel cross-section is surrounded by the housing and secured accordingly, this already existing device is now also advantageously used to record various equipment essential for the tunnel construction. In particular, intended for drilling and Ankersetzeinrichtungen, Spritzbetonmanipulatoren, chargers or work platforms. Rails in the radial and / or axial direction on the outside of the support frame formed by the housing ensure the mobility of the units and thus their simultaneous use. By simultaneous and at least temporally minimally offset work such as securing the old tunnel vault, anticipatory anchoring, adjusting the protective roof, drilling the holes and filling the holes, securing the extension by shotcrete and loading and removal of the mountains can save considerable time and ultimately a tunnel can be rehabilitated much faster and therefore cheaper.

At the objects of the FIGS. 1 to 8 and 11 to 14 it is not part of the invention.

FIG. 1 These are the drilling and tethering device 17, 18 and the spray manipulator 16 at the rear end 19 of the housing 1. Both are movable in the longitudinal axis direction 25 of the housing 1, wherein the drilling and tethering device 17th 18 is located in the direction of advance 30 in front of the spray manipulator 16. Accordingly, the drilling and anchoring device 17, 18 to the front end 20 of the housing 1 can be moved. The drilling and bolt setting device 17, 18 and the shotcrete manipulator 16 are on the one hand on rails 9, 12, 9 ', 12' in the radial direction, relative to the housing 1 movable. On the other hand, the mobility is also given in the direction of the longitudinal axis 25, namely on the rails 12. As shown in FIG FIG. 1 the housing 1 thus prepares itself in the tunnel 7 by first drilling holes 17 by means of the drilling device, then blasting is carried out in order to then secure the expansion ring over the shotcrete manipulator 16. The enclosure 1 itself forms the framework for the various units 2. It consists of a stud 3 with panels 4, suitably made of sheet metal.

FIG. 2 illustrates that the housing 1 on the one hand in its interior, the area to be protected 5 in the form of the remaining tunnel cross-section 6 serves as protection for the tracks 27 traversing trains. On the outside 8 there are the rails 9, 12 for the units 2, of which the tethering device 18 is shown here by way of example. Good to see is also the bow-like construction of the rails 9, 12, which extend by about 180 ° over the upper half of the enclosure 1. This leaves a sufficiently large space in the form of the remaining cross-section 28 for work that can be performed without endangering the housing 1 passing vehicles.

In this residual cross-section 28 is located, as in FIG. 3 illustrated, the charger 26 exemplified here with working platform 29, which is not integrated into the housing 1 in this illustration. On the outside 8 of this housing 1 are the two bridges 21, 21 ', which are arranged there movable and serve to accommodate the various units 2.

In frontal view, this enclosure 1 is again in FIG. 6 shown.

The various variations also show the once again FIGS. 7 and 8 with the anchor setter 18 at the front end 19 of the housing first Various positions of the anchor setter 18, denoted by the further reference numerals 18 ', 18 ", 18"', 18 "" shows FIG. 8 ,

In the FIGS. 9 and 10 an enclosure 1 is shown, in which it is primarily about the mobility of the units 2 in the direction of the longitudinal axis 25. To recognize rails 9, 11 in the axial direction in FIG. 10 while in FIG. 9 illustrates that three pairs of rails 13, 14, 15 are arranged parallel to each other in the upper region of the housing 1. The pairs of rails 14, 15 serve to accommodate drilling devices 17, 17 ', while the central rail pair 13 serves to receive a shotcrete manipulator 16.

Another variant of the invention show the FIGS. 11, 12 and 13 These are shown here in the decoupled state, wherein a part 22 of the housing 1 is designed as a support frame for receiving the propulsion units serving 2, while the other part 23 is a pure protection device 24 without aggregates offers. Again, the drill 17 is shown as an aggregate 2 in two different positions 17, 17 'in order to emphasize the flexibility of this housing 1. In this embodiment, the drilling equipment 17 and the spray manipulator 16 are struck as aggregates 2 fixed to the portal formed by the part 22 of the housing 1.

FIG. 14 shows the housing 1 with located on the outside 8 working platforms 33, 33 '. The work surfaces 34, 34 'are designed to be foldable in the directions of arrows 49 and 15. These are located directly on the portal and do not need to be brought into the work area via separate vehicles. Furthermore, also provided with the reference numeral 45, serving as a catenary for electric locomotives contact wire can be seen. This contact wire 45 is located below the rail 12 in the region of the upper edge of the remaining tunnel cross-section 6. The protective device 24 is formed in height above the cylinder 56, 57 adjustable.

FIG. 15 illustrates how the protective device 24 serves to protect the old tunnel cross-section 52 during blasting and is located in the front area of the housing 1 for this purpose. The protective device 24 may be arranged to be movable. By way of example, further units, hydraulic hammers, drilling and anchoring device are provided with the reference numerals 40, 17 and 18 in this housing. The reference numeral 43 designates the intake port, which, in conjunction with the inflatable tube 44 between the old tunnel cross-section 52 and the housing 1, ensures that the dedusting works.

Finally shows FIG. 16 in particular, the additional installation portal 46 as a further decoupled part 32 of the enclosure. About this installation portal 46 concrete and other expansion elements, such. B. tubbing for the tunnel lining by means of the installation portal 48 provided on the installation device 48 can be installed. This installation device 48 in turn is movable on rails 53, 54 in the axial or radial direction. The reference numeral 40 designates the hammer, 16 the shotcrete manipulator. Furthermore, the charger 36 in the form of the conveyor 37 or inclined conveyor 38 with the loading apron 39 and the upper discharge 55 can be seen. As a transport vehicle 41 here is a truck 42, which can advantageously transport the tubbing in order to then be able to carry away the supplied via the charger 36 mountains. The housing 1 according to the invention alternatively or additionally also offers the possibility of transport via a monorail monorail.
