Definitions

  • the invention concerns a transport device for use in driving tunnels with a tunnel boring machine (TBM), where the excavated material is transported away from the tunnel boring machine by a conveyor belt with a support construction preferably mounted on wheels and with a belt magazine.
  • TBM tunnel boring machine
  • a belt magazine is normally used in order to extend the belt as the tunnel boring machine advances.
  • This magazine is usually provided at the back-up rig, but systems are also known in which the belt magazine is located at the other end of the conveyor belt, but in the hitherto used systems a parallel-running transport system is established for transport of men and equipment, with or without tracks.
  • the combination of conveyor belt and transport system for men and equipment will require a tunnel diameter of approximately 4.5 m.
  • the object of the present invention is to rationalize the total transportation system in tunnel boring machine operations.
  • cutters with split rings will preferably be used whereby it will be sufficient to replace cutter rings which can be conveyed to the tunnel face by a person by hand.
  • the transport system should permit the supply of water, air, energy, audio-visual communication equipment etc. in such a manner that no equipment for the tunnel operation is affixed to the tunnel's surface. This permits a simplification or even elimination of the supplementary work involved in removing all the equipment necessary for transport of men and materials, air, water and electricity, etc. which has to be performed after the tunnel is completed, but before it can be put into service.
  • a further object is to provide greater safety for the crew during the actual boring with the tunnel boring machine.
  • the basic principle of the device according to the invention is to employ a conveyor belt system for the removal of excavated tunnel material.
  • This con ⁇ veyor belt has a support structure which preferably run on wheels, but may slide on the tunnel wall.
  • This construction is designed in such a way as to provide transport means for all transport requirements.
  • the main girders of the support construction may therefore be used as supply lines for water, ventilation and compressed air, etc. to the tunnel boring machine, or water etc. out of the tunnel.
  • the support construction is further equipped with hooks for the suspension of power lines and other cables, such as, e.g., telephone, TV, lights etc.
  • a principle feature of of the device according to the invention is that the conveyor belt carrying structure also includes a trackway for transport units for men and equipment.
  • the machine's operator cabin may be located outside the tunnel, as instrument signals etc are transmitted via cables which are suspended on the support system.
  • the operation of the tunnel boring machine is thereby controlled and monitored via television screens and other audiovisual aids.
  • a further advantage which is achieved by means of the invention is that with this transport system the equipment may be rapidly removed from the tunnel after the drilling is completed, and by pulling at the entrance end of the transport system both back-up rig and tunnel boring machine may be pulled out. All lines and cables will be pulled out along with the carrying structure and winded onto reels, thus leaving the tunnel ready for operation as soon as the tunnel driving equipment has been removed. Since the tunnel has no trackway that reduces the tunnel area, it is only any eventual lining which may reduce the diameter, thus enabling withdrawal of the tunnel boring machine to be made with a minimum dismantling of elements. The improved efficiency will considerably reduce the time needed to put the tunnel into service.
  • Fig. 1 is a schematic view illustrating the drving of a tunnel with a tunnel boring machine and the devices according to the invention, with a cross-section view A-A in Fig. IA, fig. 2 is a view illustrating the tunnel exit and the installation of the special belt magazine,
  • fig. 3 is a cross section view of a tunnel and of a device according to the inven ⁇ tion,

  • fig. 5 a cross section view of a modification of the embodiment in fig. 4,
  • fig. 6 a length view of a frame section of the invention.
  • the length of the actual tunnel boring machine is usually between 10-15 m.
  • the back-up rig which is necessary for operating the acutal tunnel boring machine may have a length of 10-30 m. To this must be added a loading system which often is over 100 m long for conventional rail operation. For operation with conveyor belt with belt magazine behind the tunnel boring machine, the belt magazine often has the same length.
  • the back-up rig is shortened to a fraction of that of hitherto known systems and will normally only have a transformator with its electrical switches and air handling systems for air sirculation, and preferably have the operator cabin at the tunnel entrance where the belt magazine also is located.
  • the number of loops in the belt magazine is adapted to suit the local conditions with regard to space.
  • Fig. 1 shows a design according to the invention.
  • the actual tunnel is indicated by 1.
  • the tunnel may also be curved.
  • the tunnel boring machine is indicated by 2 and illustrated innermost in the tunnel, while the back-up rig is indicated by 3.
  • Behind the back-up rig 3 follows the device according to the invention, which consists of a support structure 4, which supports a conveyor belt 5.
  • the back-up equipment 3 is preferably sledge mounted, while the support structure 4 are mounted on wheels which run on the tunnel floor and may be steered by a gravity pendulum wheel.
  • the required tractive power to be exerted by the tunnel boring machine 2 thereby becomes relatively modest, even with a tunnel length of several kilometres.
  • the force in the conveyor belt 5 will normally be sufficient to pull the back-up rig and support structure 4 with belt 5 backward and maintain a tractive power in the connection 7 to the tunnel boring machine.
  • connection arm 7 or the connection arm 7a between the back-up rig and the conveyor belt support structure 4 the entire tunnel cross section is made available for any special work which may be necessary, for instance grouting, lining, concrete spraying.
  • a control panel is mounted in the back-up rig, duplicating the control panel in the operator cabin at the tunnel entrance. This control panel is used for carrying out any securing work in the tunnel or when servicing the tunnel boring machine equipment.
  • the conveyor belt 5 leads from a loading point at the end of the back-up rig 3 to an unloading point outside the tunnel.
  • the conveyor belt and its support construction 4 are more clearly illustrated in fig. 3 and 4.
  • the support structure is provided with wheels 6, but runners may also be used.
  • the support structure is composed of four longitudinal girders 8, 9, 10 and 1 1, of which one or more are hollow and buttressed with intermediate stays which are not specifically indicated.
  • On the outside of one of the lower main girders may be located brackets for a footpath 19.
  • the distance between the lower girder 10, 11 of the support construction 4 is greater than the distance between the two upper girders 8, 9.
  • the support construction 4 is preferably made of aluminium in order to keep the weight low and avoid rust and save painting.
  • On the two upper girders 8, 9 of the support structures 4 are provided tracks for the wheels of a transport unit 14.
  • This rail track 17 is of steel and is bolted to the girders so they may be exchanged individually.
  • Other embodiments are also possible, for instance by special wheel design.
  • the vehicle 14 is used for transport of men and equipment to the tunnel boring machine or out from it. However, the transport of material by the vehicles 14 cannot pass the loading point for the tunnel material on the belt during drilling.
  • the vehicle By suspending the loading funnel 15 pivotally when drilling is halted, the vehicle may be driven up to the support structure's end point 16, where heavier loads are unloaded.
  • the tunnel floor should be free of obstacles from this point up to the drilling head, thus enabling heavier material to be transported on the tunnel floor on this strecth by means of a winch in the known manner.
  • Fresh air is supplied via one or more of the hollow main girders 8, 9, 10 and 11 in the support structure for the conveyor belt.
  • the girders with the largest opening are preferably used for fresh air, while smaller ones may be used for water or compressed air as required. If the conveyor belt carrying structure has only one hollow element as shown on fig. 4, it will be used for fresh air.
  • the optional tubes 26, 27 may be used for other purposes. Cable for power supply may be suspended on hooks 18, preferably on one of the upper girders.
  • the main power cable and other cables should be suspended on opposite sides of the support structure. As mentioned above, these girders are also designed as rails for the transport vehicle.
  • flanges for joining the girders 8 and 9 are given the same cross section shape as the upper part 13 of said girders or the ends of said part 13 are cut out so that the upturned support surface goes right up to the joint with the girders 8 and 9.
  • the track 17 is preferably made of steel and is bolted to the main structure.
  • the individual support structure section is preferably assembled by bolts or screws for easy dismantling.
  • the dimension of the greater hollow elements should preferably be chosen to allow the smaller to be put inside the bigger.
  • the section length should preferably be under 6 m, making them suitable for container transport.
  • the tubular elements at the structure are preferably interconnected by clamps and cardan couplings as used in quick-coupling pipes.
  • the transport vehicle 14 can be operated by muscle power or a motor. When an accumulator and electrical motor is used the transport vehicle may be remotely controlled using well known technique. Combined with telephone system it may provide savings since goods may be transported without being accompanied by a person.
  • the use of a system for tunnel boring machine operation as described provides a back-up rig which is simpler and with fewer units which require inspection than in the known operational systems.
  • the actual boring of the tunnel may be performed without people in the tunnel and the efficiency of men and equipment is improved. This results in faster tunnel excavation at reduced cost.
  • the system also saves the work of removing ventilation and rails and the clean up work after break-through, thus substantially reducing the time needed to put the tunnel into service.
  • the transport system which is pulled by the tunnel boring machine will allow the tunnel boring machine to pull several kilometres of conveyor with its carrying structure as the tunnel boring machine advances. Quite simply, new sections of the belt carrying structure are added at the free end of the transport construction. Likewise are cables, water tubes and conveyor belt sections added at the tunnel entrance.
  • Fig. 1 also illustrates the operator cabin 20 located outside the actual tunnel.
  • the structure in fig. 3 is principally for tunnels without curves.
  • the figures 4, 5 and 6 illustrate two embodiments of the invention's carrying structure 4, which are for tunnels which run in curves.
  • the main support element of the frame work is a hollow girder 10 for fresh air to the tunnel boring machine, and with elements 20, 21 and tracks 17, the wheel 6 and the conveyor belt 5.
  • This embodiment is of advantage when the tunnel is curved as there will only be the tubular elements 10 which are connected to one another.
  • This connection has spheric connectors "cardan couplings" as used for quickcoupling tubes.
  • the wheel 6 are mounted on ball or roller bearings 22 so they rotate around their centre pins 23.
  • the wheels When running through a curve the total structure will be drawn up on the tunnel wall on the inner side of the curve by the conveyor and the rails track will get a transversal angle.
  • the wheels have an arm 24 which is connected to a pendulum 25 fixed to the rail 17.
  • the pendulum 25 When the structure moves to one side the pendulum 25 will turn the wheel in the opposite direction provided the pendulum is mounted in the forward direction of the movement of the structure.
  • the arm 24 and the pendulum 25 may consequently be mounted on either side of the wheel 6 depending on the structure being pulled inward or outward at the tunnel.
  • Tubes 26 and 27 are optional.
  • a side support arm 28 with a wheel 29 that extends in the direction of the curve centre to some few centimetres distance from the tunnel wall when the centre plane of the conveyor belt carrying structure and the tunnel centre plane are coinciding.
  • Each section will have one side support.
  • the support wheel 29 shall preferably run at the vertical part of the tunnel wall when activated.
  • Fig. 5 shows the configuration of the side support arm 28 and its wheel 29 in a bigger tunnel than on fig. 4.
  • the conveyor belt with support structure are identical in figures 4 and 5, but a distance element 30 has been inserted at the wheels 6. Construction elements for pendulum or side support are all made simple to connect/disconnect so they may be mounted to some of the structure sections before they enter the curve of the tunnel and dismounted after passing the curve.
