Definitions

  • the invention relates to a method for rehabilitation and extension of existing tunnel profiles, in which after an optional disassembly of an inner shell of the tunnel to be rehabilitated in a further step, the outer rock is removed.
  • the invention relates to a chisel for equipping an automatic hammer used for rehabilitation and expansion of existing tunnel profiles for carrying out this method and a mobile enclosure with a stud and a lining for temporarily secured areas, especially for tunnel cross-sections which are not subject to traffic during the renovation of existing ones Tunnel profiles, in which the enclosure is designed as a supporting framework for receiving units serving for the propulsion.
  • the inventive method is particularly well suited for the rehabilitation of railway tunnels. Due to tunnel damage, changing operating conditions or newly imposed guidelines and standards, the need for refurbishment of existing tunnels is considerable. Of particular importance for the choice of a suitable construction measure for the rehabilitation, renewal or expansion of an existing tunnel are the expected levels of intervention in traffic, especially in railway operations. Interruptions or diversions should be avoided as strictly as possible. Especially with single-tracked or reduced during the construction of a track double-railed tunnels renovation work such as a profile widening with arched outbreaks and production of an inner shell so far only possible with complete blockage of the tunnel due to the cramped space. In practice it has become Tunnel expansion established a tool combination of hydraulic hammers and drills. The old vault and its back packing are mechanically broken.
  • this object is achieved in that the rock to be removed is first perforated in sections by means of a plurality of bores and that the rock is subsequently released and / or split off by a splitting action exerted on the bores via an automatic hammer equipped with a conically designed bit.
  • the old inner shell of the tunnel to be rehabilitated is removed.
  • This is usually z. B. made of natural stones or brick and is torn by means of hydraulic hammers.
  • the extension of the profile then takes place by removing the rock.
  • a partial perforation of the rock in the region to be removed takes place by producing a plurality of bores.
  • These are then used as a starting point for the targeted use of an automatic hammer.
  • a particularly accurate profile extension can be achieved by ensuring the separation of a largely exact amount of rock. All work can be carried out while the traffic is running without any blocking break or other obstruction, since the space required for the procedure is particularly low.
  • the use of the automatic hammers to loosen the rock is advantageously controlled so that slipping or flying rock does not interfere with railway operation through the tunnel-in-tunnel system.
  • the bit has a cone whose front end is smaller than the diameter of the borehole and whose rear end is larger than the diameter of the borehole.
  • the bit at the front end of the cone has a diameter of about 100 mm and / or at the rear end of the cone has a diameter of about 220 mm in order to achieve the effects mentioned.
  • the cone extends over a certain amount in the region of the front end of the chisel. It is envisaged in this context that the length of the cone is about 500 mm.
  • the bit is formed at its front end as a flat chisel or has such a flat chisel.
  • the object according to the invention is achieved in that the aggregate used is at least one automatic hammer, which is arranged to be movable on a carriage arranged on a console in the longitudinal direction and / or in the transverse direction.
  • Such housing serves on the one hand as protection of the remaining free for vehicles residual tunnel cross-section and on the other hand as a basis and support structure for various propulsion units serving such.
  • one or more automatic hammers are provided, which are movable on the housing. Serves for this purpose a carriage positioned on a console, to which this automatic hammer is assigned and which is arranged to be adjustable in the longitudinal direction and / or in the transverse direction.
  • a hammer proves to be particularly agile and flexible, because all workspaces are accessible and if possible over the entire length as the entire scope of the mobile housing.
  • an unlimited number of aggregates can be used in parallel in this way.
  • a plurality of consoles are arranged laterally and / or on the housing.
  • the enclosure has three such consoles, each with an automatic hammer, each one console side and a top of the housing arranged.
  • These brackets can be rigid or in turn movable.
  • At least one axis of rotation is provided between the console or the carriage and the multi-function arm.
  • the multi-function can be rotated together with this at its opposite end associated automatic hammer.
  • At least one pivot axis is provided between the console or the carriage and the multi-function arm.
  • the multi-function arm with hammer is pivoted in this way about an axis that is assigned to either the console or on this adjustable slide.
  • the invention is characterized in particular by the fact that a method and a device for the rehabilitation and extension of existing tunnel profiles are created, which allow in several ways new ways in the rehabilitation of tunnels.
  • Even rock of maximum hardness can be degraded in the process of the invention by way of splitting, without causing an impairment of the traffic in the tunnel.
  • the rock is then selectively dismantled by automatic hammers.
  • Such a hammer is equipped as a machining tool with a chisel as a splitting tool, which in turn has a cone to improve the wedge or gap effect.
  • a hammer in turn is according to the invention on a mobile housing, positioned on a so-called "tunnel in the tunnel and on a multi-function arm arbitrarily swivel and rotatable and additionally on a carriage in the longitudinal direction and / or in the transverse direction arbitrarily adjustable on the housing.
  • the battered multifunction arms for the hammers can thus be additionally adjusted in height on the protective housing. Furthermore, a pivoting of the attachment point for the multi-function can be done.
  • FIG. 1 shows the section of a mobile housing 1, consisting of a stud 3 and panels 4.
  • a mobile housing 1 On the mobile housing 1 is in this illustration next to the platform 21 a trained as an automatic hammer 5, laterally positioned on the housing 1 unit 2 can be seen.
  • the hammer 5 is assigned to a multi-function arm 9.
  • the latter is associated with the carriage 10, which in turn is arranged on the bracket 6 in the transverse direction to the longitudinal axis 24 movable.
  • the bracket 6 is in this embodiment of the invention in the direction of the longitudinal axis 24 on the Housing 1 adjustable.
  • a pivot axis 12 is located at the upper end 25 of the carriage 10. It thus takes place a pivoting of the attachment point of the multi-function arm 9 in order to represent its movements even shorter and more compact.
  • FIG. 2 the enclosure 1 is shown with a located on the console 6 in its lowest position carriage 10 so that the corresponding applies to the multifunction arm 9 together with automatic hammer 5 and chisel 15, so that the sole 5 can be reached via the hammer 5.
  • Cylinders 26, 27, 28 ensure the various adjustment possibilities of the carriage 10 or of the multifunction arm 9.
  • FIG. 3 shows an enclosure 1 with the panel 4 and a unit 2 arranged thereon in a rear position. More precisely, is located at the top 13 of the housing 1 a permanently installed here console 6. On this console 6, a carriage 10 is transverse to the longitudinal axis 24 of the housing 1 adjustable or movable.
  • the reference numerals 11 and 22 respectively denote the axes.
  • the unit is in the out FIG. 4 in a forward position.
  • the carriage 10 together with the unit 2 is moved accordingly in the longitudinal axis direction 24 to the front to edit the mountains 8.
  • FIG. 6 shows in addition the side view of a housing 3 with the arranged on the top 13 aggregate 2.
  • the carriage 10 in the longitudinal direction 24 of the housing 1 is movably positioned. Thanks to the Caribbeanspiels diverse cylinder 33, 34 and the rotation and pivoting possibilities about the axes 11, 22 and 35 can be achieved with the automatic hammer 5 and the chisel 15 almost any position and solved in accordance with rock or split off.
  • FIGS. 7 and 8 An alternative embodiment of this show the FIGS. 7 and 8 , There, a console 6 is positioned laterally on the housing 1. About the carriage 10, the unit 2 together with the drill arm 9 is maximally between the rear in position FIG. 7 rear and the front position in FIG. 8 traversable. Thus, positions are high up, as in FIG. 7 illustrated, or in the area of the sole, as in FIG. 8 shown, realizable.
  • FIG. 9 Subject of FIG. 9 is a chisel 15.
  • the chisel 15 is received with its rear end 29 of the automatic hammer, not shown here, including the constriction 31 is used.
  • the focus is here on the front end 30 of the chisel 15, where a cone 16 is located.
  • the cone 16 extends between its front end 17 and its rear end 18 evenly between the two diameters d1 and d2, preferably in a ratio of 1.0 / 2.2, in order to realize a favorable effect in the splitting of the rock.
  • At the tip 32 of the bit 15 is a striking bit 19 instead of a round tip to chisel away small bumps can.
