Definitions

  • the invention relates to a method for free-milling a manhole cover and / or a manhole cover bearing with a round milling head and to an apparatus for carrying out the method.
  • manhole covers and manhole covers are free-milled or drilled during the rehabilitation of manholes, such that a cylindrically constructed milling or boring head reams or drills the manhole cover and the manhole cover rest freely. Vertical milling edges are produced and the manhole cover support with the manhole cover is lifted out.
  • the manhole covers installed in the refurbishment of the prior art are nowadays designed for larger loads, for example up to 40 tons.
  • the entire substructure of the shaft is not designed for these high loads, especially in older shafts. This means that either the entire manhole base has to be replaced, which is very costly, or the substructure is not removed, which then often settlement damage occur.
  • the prior art includes a method and apparatus for repairing or replacing parts of the bituminous pavement around a duct ceiling or the like.
  • a device with a centering tree is arranged in a shaft head.
  • the centering tree has centering arms which center a centering slide over a shaft head.
  • a milling head is arranged, which is rotated by the cutter receiving arm by 360 ° about the centering.
  • a recess is formed around the manhole cover receptacle.
  • the manhole cover must be removed to center the centering tree in the manhole cover space.
  • the milled material is thrown into the open manhole and the channel then has to be laboriously cleaned.
  • the formation of the recess is very complicated, since the milling head with the cutter receiving arm has to be pivoted through 360 °, and thus the milling process takes a relatively long time.
  • the method and the device according to this prior art have the further disadvantage that the device must be centered very exactly.
  • the centering must be vertically formed absolutely exactly, so that a uniform recess can be milled around the manhole cover receptacle.
  • the prior art (DE 43 26 000 A1) includes a pin drill bit for beating drilling.
  • This pin drill bit has a conically tapered drill head having an end face with inserted carbide pins. With this drill bit, however, it is only possible to create drill holes. A free milling of manhole cover recording is not possible with this belonging to the prior art drill bit.
  • the prior art further includes a device with which a manhole cover pad can be milled free.
  • This belonging to the prior art device has an inclined cutting edge, wherein the inclined cutting edge is formed as a circumferential axis about a central axis of the device cutting.
  • This device which belongs to the prior art, also has the disadvantage that the formation of the recess is very complicated, since the cutting edge has to be pivoted through 360 ° around the device. As a result, the processing takes a long time.
  • the prior art (DE 298 23 787 U1) a device for milling or drilling, which has a support frame with at least two support legs. On the support frame is a milling or drilling tool arranged.
  • a milling or drilling tool arranged on the support frame.
  • the formation of an oblique edge is not provided according to this document.
  • the prior art also includes a device for exchanging a frame of a manhole cover embedded in an asphalt surface.
  • the vertical milling edge formed in this case has the disadvantage that the built-in manhole cover can not permanently carry the large loads occurring today, for example up to 40 tons, so that after a relatively short time the manhole must be rehabilitated again.
  • the technical problem underlying the invention is to provide a method for free-milling a manhole cover and / or a manhole cover, in which the said disadvantages do not occur, as well as a device for carrying out the method.
  • the manhole cover and / or manhole cover bearing are milled free with a round milling head, with the round milling head by lowering the milling head in the vertical direction an annular opening is formed with an oblique milling edge, and in that the milling head the Manhole cover and / or the manhole cover rest completely surrounds, it is possible to form the annular opening with the oblique milling edge in a single operation by a single lowering of the milling head.
  • the manhole cover and / or manhole cover with a round Milling head which produces an oblique milling edge, are milled free, a bore with an oblique milling edge is present in a renovation or a new construction of the shaft, in which a new manhole cover pad is used.
  • This new manhole cover support is based on the oblique cutting edges in the support layer of the road asphalt, so that not the entire load of manhole cover and the manhole cover is supported by the substructure, but a large part of the pressure is absorbed by the asphalt or the ground.
  • a rehabilitation of a shaft is possible in such a way that the manhole cover and / or the manhole cover rest are milled free with an oblique milling edge.
  • the manhole cover and manhole cover are then removed. Thereafter, a new manhole cover rest is inserted into the free-formed opening with the oblique cutting edges, and the manhole cover is finally inserted into the manhole cover rest.
  • a manhole cover which also has conically tapered side surfaces.
  • an optimal distribution of force is achieved on the surrounding asphalt.
  • the Inclination angle of the tapered side surfaces formed substantially equal to the inclination angle of the oblique Fräskanten.
  • an optimum distribution of force is achieved on the support layer of the asphalt and the shaft substructure.
  • a mortar is introduced into the opening with the oblique edges milled free in accordance with the method according to the invention.
  • This is preferably a high-strength, fast-curing assembly or grouting mortar.
  • This mortar fulfills two tasks. On the one hand, a frictional connection between the manhole cover support and the oblique edges of the milled opening is thereby achieved. As a result, the manhole cover rest optimally supported on the asphalt carrier layer. On the other hand, it is possible through the mortar to make a height compensation of the manhole cover overlay when inserting, so that in the end a flat surface is formed and the manhole cover rest at the same height as the road surface.
  • the oblique milling edge is formed with a milling head, which also has a conically tapered shape.
  • the side surfaces of the milling head, which are conically tapered, are occupied with milling bits.
  • the lower annular edge of the milling head has additional Fräsm facedel.
  • the milling head according to the invention is arranged on conventional milling devices.
  • This device has a support frame.
  • the support frame in turn has three support legs in order to achieve a firm footing during the milling process.
  • the device is arranged on a carrier vehicle, such as an excavator, backhoe or crane.
  • the engine of the device is driven by a hydraulic system of the carrier vehicle.
  • the device has an outer and an inner guide frame, wherein the milling head according to the invention is arranged on the inner guide frame.
  • This inner guide frame is vertically displaceable against the outer guide frame.
  • the loads can be transferred to the intact area further out with an additional cone ring.
  • the cone ring has an adapter function.
  • Fig. 1 shows a device (1) having a conically tapered milling head (2).
  • the milling head (2) has on its side surface (3) milling chisel (4).
  • a lower annular rim (5) also carries milling bits (6).
  • the device is designed as a mounting device on a carrier vehicle (not shown).
  • the device (1) has for this purpose a suspension (7).
  • the device (1) is supported by three support legs (8, 9, 10).

  • the manhole cover (12) is arranged in an asphalt carrier layer (15) and an asphalt cover layer (16).
  • the opening (17) has obliquely running milling edges (18, 19).
  • the shaft substructure with the shaft cone (14) of the shaft (11) is retained.
  • a mortar (20) advantageously introduced a high-strength, fast-curing grout into which in turn a manhole cover (21), as shown in Fig. 3, is used.
  • the manhole cover also has conically tapered side surfaces (22), the inclination angle of the inclination angle of the oblique Fräskanten (18, 19) are adjusted.
  • the manhole cover (21) is inserted into the mortar (20). On the one hand, this results in the frictional connection between the manhole cover support (21) and the asphalt carrier layer (15). On the other hand, this height compensation is possible, so that a flat road surface (23) is formed.
  • the manhole cover support (21) additionally rests on a substructure (24) from the grouting mortar (20). With the substructure (24) the actual height compensation is made.
  • the manhole cover (21) has a peripheral edge (27) for over-paving in the ceiling exclusion.
  • the manhole cover (25) is inserted into the manhole cover. Before or after insertion of the manhole cover (25), a fine layer (26) of asphalt is finally applied to the asphalt carrier layer (15).
