Definitions

  • the present invention relates to an apparatus for digging into the ground very deep trenches.
  • drilling rigs of the type comprising a chassis suspended by cables from a lifting device, chassis at the bottom of which milling drums are rotated in opposite directions to break up the ground by allowing said chassis to sink into the ground to dig an excavation.
  • a rectangular frame is made on the ground. concrete whose inner section corresponds substantially to the outer section of the chassis, position the chassis inside the frame by resting it on the ground while the milling drums are turning.
  • the chassis then begins to sink into the ground while being held in its working position by the frame.
  • the orientation of the chassis remains suitable, which makes it possible to obtain boreholes which, after meeting, form a continuous trench and substantially flat.
  • the chassis may tend to follow a path helical, i.e. it can sink into the ground by turning around its vertical longitudinal axis.
  • the applicant company has already written in the patent EP-A-0 592 325 an apparatus for digging trenches in the ground of the same type as above, in which the chassis is further provided with its upper part of a freely pivoting muffle by which it is suspended from the lifting gear. Thanks to this freely swiveling block, the chassis can be oriented by hand before starting an excavation, in particular by positioning it obliquely to the hoist, allowing, by playing on the length and orientation of the mast of the hoist, position the chassis above a guide frame, without having to place the lifting device strictly at the perpendicular to this frame. This is particularly advantageous when want to drill perpendicular to a non-movable obstacle such as a corner of building.
  • the present invention aims to provide a simple and economical device which resolves in particular the drawback recalled above.
  • the present invention relates to an apparatus for performing trenches in the ground of the type intended for digging excavations in progress vertically in the ground, comprising a frame provided, at its upper part, with a swivel block for suspension by a cable to a lifting device and, at its part lower, of milling drums able to disaggregate the ground on a section allowing the chassis to pass in the wake of the milling drums, the device further comprising a hose which connects it to the ground surface and serves for evacuation ground debris torn off by the milling drums, characterized by the fact that the swivel block is motorized.
  • the debris removal hose is also referred to as of mud hose, because the excavation is dug under mud and debris is evacuated by pumping mud in the vicinity of the milling drums.
  • the invention it is possible to correct any untimely rotation of the chassis in the drilling, due to the fact that the motorized muffle allows to print a torque of rotation to the chassis, by leaning either on the cables which connect the muffle to the lifting device and on the mud hose, possibly only on the muffle cables.
  • the mud hose which is usually a six-inch pipe of diameter provided with a frame, in fact provides sufficient support for the motorized muffle of the device according to the invention gives the chassis a couple of rotation to correct the orientation of the device in the excavation.
  • the muffle is consisting of a simple rotating joint comprising an upper part connected to the lifting gear and a lower part connected to the chassis, the two parts of the joint being axially pivotable with respect to each other, around a connected channel with the mud hose which allows pumping debris pumped in the vicinity of the milling drums.
  • a motor integral with the lower part of the rotating joint meshes then a toothed wheel secured to the upper part of the rotary joint.
  • the muffle is constituted by a multiple rotating joint which comprises, in addition to the central channel connected to the mud hose, at least one peripheral annular channel for the passage of the pressurized fluid supplying the chassis motors.
  • a motor meshing a gear can be used to rotate the bottom of the seal rotating relative to its upper part.
  • the muffle is constituted by the structure described in French patent application No. 2,696,758, a motor having been added to motorize the muffle.
  • the connector which connects the channel to the mud hose is designed to allow axial pivoting of the muffle relative to the flexible mud, so as to release said hose from torsional stresses which may appear when lowering the chassis into the trench.
  • this swivel connector is locked in rotation, to allow the muffle to rest on the mud hose and on the muffle cables to give the chassis a torque.
  • the present invention also relates to a method of making trenches using a drilling rig of the type comprising a frame provided with its upper part of a swivel block connected by cables to a lifting machine, chassis at the bottom of which milling drums are driven rotation to break up the terrain by allowing said chassis to sink into the ground, said apparatus further comprising a hose which connects it to the ground surface and is used for the evacuation of ground debris torn off by the milling drums, this process being characterized in that it consists in detecting a possible rotation of the chassis relative to its vertical longitudinal axis and to rotate the block rotating in the opposite direction to that of the chassis rotation to print a torque on the chassis by pressing on the hose and / or cables.
  • the apparatus shown in the drawing includes a lifting device consisting of a platform 1 provided with tracks 2, and on which rest in particular an articulated mast 3, a reel 4 for a large mud hose diameter (not shown) for reassembling the cuttings, reels 5 for oil pressure hoses, a winch 6 for the lift cable (not shown), and a device 7 for controlling and monitoring the various organs of the device.
  • a lifting device consisting of a platform 1 provided with tracks 2, and on which rest in particular an articulated mast 3, a reel 4 for a large mud hose diameter (not shown) for reassembling the cuttings, reels 5 for oil pressure hoses, a winch 6 for the lift cable (not shown), and a device 7 for controlling and monitoring the various organs of the device.
  • a chassis 8 is suspended by the lift cable (not shown) at the free end of the articulated mast 3, the cable being engaged on a fixed block at the end of the mast and on a motorized swivel block 9 at the top of the chassis 8, which allows the chassis to be oriented in any direction.
  • This pivoting block 9 which is shown in section in FIG. 2, comprises an upper part 10 intended to be suspended from the hoist and a lower part 11 secured to the chassis, these two parts being pivotable one relative to each other around a vertical axis 12.
  • the upper part 10 of the muffle comprises two pulleys 13 for the passage of the lift cable 14 and a plurality of connections 15 for hydraulic hoses 16, the whole being mounted on a plate 17 a .
  • a hub 17 b integral with this plate 17 a extends downwardly defining seven peripheral grooves 18 distributed axially along the outer surface of this hub.
  • a central channel 19 extends over the entire height of this hub.
  • the lower part 11 of the muffle comprises a cylindrical body 20 which surrounds the hub 17 b and comprises seven annular grooves 21 of rectangular section on its inner face, opposite the peripheral grooves 18 of the hub, separated by grooves 22 of smaller dimensions which house seals 23 between the grooves.
  • the grooves in correspondence of the hub 17b and the cylindrical body 20 define peripheral annular channels which are each connected to a connector 15 of hydraulic hose leading to the upper part of the muffle by a specific channel 24 formed in the plate 17 a and in the hub 17 b .
  • annular channels are each connected to a connection of hydraulic hose 25 leading to the lower part of the block through a channel specific 26 produced in the body 20.
  • the mechanical connection between the fixed part of the muffle 17 a , 17 b and its rotating part 20 is carried out using an annular bearing 30 whose external ring 32 is integral with the fixed plate 17 a and whose internal ring 34 is secured to the upper end of the cylindrical body 20.
  • the central channel 19 of the hub extends into the lower part of the muffle and allows the passage of delays pumped in the chassis in the vicinity of milling drums. It is connected to the mud hose 27 by a swivel connector 28 which can be locked in rotation.
  • the axial passage 19 of the hub 17 b is extended by a cylindrical sleeve 36 fixed on the upper face of the plate 17 a .
  • This sleeve is connected to the lower end 27 a of the mud hose 27 by the pivoting connector 28 integral with the end 27 a and into which the sleeve 36 enters in rotation.
  • the axial passage 19 is extended by a pipe for raising the cuttings, the pipe 38 being integral with the chassis 8. It is not necessary to provide a seal between the passage 19 and the pipe 38 since this assembly is immersed in the drilling mud.
