Definitions

  • the present invention relates to an apparatus for the assembly by interlocking of large diameter pipes, in particular concrete pipes used mainly for sanitation.
  • Each pipe is generally lowered, surrounded by a sling attached to a crane, above the bottom of the excavation, so that its male end is located substantially opposite the female end of the pipe previously laid.
  • a cable type traction device is then hooked to a sling placed for example around one of the pipes already laid.
  • the hook of the traction device is connected to the sling supporting the pipe to be laid and the male end of the pipe to be laid is fitted into the female end of the pipe already laid by operating the traction device. During this whole operation the hose must remain suspended from the lifting sling.
  • the interlocking of two pipes can also be carried out by traction inside the pipes, using a traction device generally supported, on the one hand, on a manhole placed every forty to sixty meters in such sanitation pipes and, on the other hand, on a plank, an iron bar or the like applied crosswise against the inner stop collar of the female end of the pipe to be laid.
  • a traction device generally supported, on the one hand, on a manhole placed every forty to sixty meters in such sanitation pipes and, on the other hand, on a plank, an iron bar or the like applied crosswise against the inner stop collar of the female end of the pipe to be laid.
  • the present invention relates to an apparatus which simplifies the assembly by fitting of large diameter pipes and significantly reduces the risks of laying such pipes.
  • the invention also relates to an apparatus which makes it possible to reduce the cost of laying these pipes.
  • the apparatus according to the invention comprises a carriage capable of rolling inside the pipes laid, on the bottom of the latter.
  • the trolley makes it possible to move the device as the laying of the pipeline progresses, by assembling elementary pipes. For each pipe to be laid, the trolley is immobilized in the last pipe laid, the pipe to be laid is leveled and centered in relation to the pipe already laid and the pipe to be laid is fitted into the pipe laid by operating the device. traction.
  • the immobilization and leveling and centering device comprises at least one strut articulated between its two ends on the carriage so as to be able to pivot in a longitudinal vertical plane of the cart.
  • a sole is articulated on the lower end of this strut.
  • a vault is articulated on the upper end of this same strut so as to be able to pivot in a longitudinal vertical plane of the carriage.
  • the device further comprises an operating member for pivoting the strut so as to straighten it relative to its rest position to bring the sole and the arch against the inner face of the laid pipe, at two or two points almost diametrically opposite.
  • the strut In order to allow the use of the same device for pipes of different diameters, it is advantageous for the strut to be telescopic.
  • the struts are two in number, are mounted side by side on the carriage and are each connected to one of the two outer segments of the arch made up of three segments articulated one on the other along axes s extending in the length direction of the carriage.
  • the member for operating the strut and the traction devices are advantageously constituted by hydraulic jacks supplied by a common hydraulic pump passing through a distributor.
  • the apparatus according to the invention used for the assembly of two pipes 1,2, for example concrete comprises a carriage 3 capable of rolling inside the pipes.
  • the carriage is formed by a chassis 4, preferably welded, carried by two front wheels 5 and two rear wheels 6.
  • the wheels are inclined outward so that the planes of said wheels are substantially perpendicular to the tangent to the inner periphery of the hose, at the point of contact of each wheel with said perimeter.
  • Two telescopic struts 8 are articulated on the chassis 4, by two articulated axes 7 aligned, horizontal, perpendicular to the longitudinal axis of the carriage 3, so as to be able to pivot in two longitudinal vertical planes of the carriage 3.
  • Each leg of force 8 comprises an outer tubular section 9 articulated by said axis 7 on the chassis 4, a median tubular section 10 protruding on either side of the section 9 and capable of sliding in the latter, as well as an inner section 11 exiting towards the top of the middle section 10.
  • the tubular section 11 has transverse holes making it possible to limit, by means of pins not shown or the like, the depth of insertion of the section 11 into the section 10.
  • the two tubular sections medians 10 are interconnected, substantially at their two ends by two spacers 12.
  • Each of the two tubular sections 10 has, at its lower end, a sole 13 articulated by a ball joint on the section 10.
  • Two hydraulic cylinders 14 are articulated on the rear of the chassis 4 along aligned axes of articulation 15, horizontal, perpendicular to the longitudinal axis of the carriage 3, so as to be able to pivot in the same planes as the struts 8.
  • the piston rod of each of these jacks 14 is articulated on the tubular section 10, below the chassis 4, substantially at the lower end of the section 10, by articulation axes 16.
  • a tension spring 17 extended by a threaded rod 18 is attached to each of the axes 16, the nut 19 screwed onto the threaded rod 18 taking support on a projecting tab 20 fixed at the rear on the tubular section 9.
  • the spring 17 seeks to raise the section 10 relative to the section 9 in which it can slide.
  • a vault 21 is articulated around two aligned axes, transverse, horizontal, so that said vault can pivot relative to the struts 8 in a vertical plane longitudinal of the carriage.
  • the vault 21 is made up of several curved segments 23 articulated one on the other along longitudinal axes 24.
  • the two tubular sections 11 are articulated on the two outer segments 23 of the vault.
  • a compression spring 25 is inserted between the upper end of each tubular section 11 and the arch 21, in front of the hinge pins 22, so that the springs 25 seek to pivot the arch 21 as a whole in the direction counterclockwise in fig. 1.
  • a hydraulic cylinder 26 is mounted below the chassis 4, in the median longitudinal plane of the carriage 3.
  • the cylinder 26 is articulated by a horizontal transverse axis 27 on the lower cross member 12. Its piston rod 28 which extends towards the front ends with an eye 29.
  • the jack 26 is supported in a substantially horizontal position by a stirrup 30 fixed below the chassis 4.
  • the cylinders 14 and 26 are controlled by passing through a distributor 31, by a common hydraulic pump 32 which, in the example shown, is operated manually using a lever 33.
  • the spacing of the left and right wheels (track) both at the front and at the rear is adjustable, namely by the fact that the yokes 34 bearing the wheels can be fixed with variable spacings on the chassis 4, for example using bolts 35.
  • the front wheels 5 can be steered by the fact that their yokes 34 are fixed on a common support 36 articulated by a single central bolt on the chassis 4. This orientation of the front wheels can be advantageous for example to move the device outside of pipes.
  • Pipe 1 constitutes the last pipe laid in a series of pipes, for example concrete, constituting a pipe of a sanitation system. In the case shown, this involves assembling another pipe 2 with the pipe 1.
  • each of the pipes 1, 2 comprises a female end 37 with a collar and a male end 38 intended to be fitted into the female end 37.
  • the male end 38 carries a seal 39 made of elastomer placed in a throat. provided on male end 38.
  • the device according to the invention placed inside the pipe 1, is advanced towards the free end of the latter, in this case towards the female end 37, so that its front wheels 5 are located near the female end 37.
  • the overall length of the struts 8 is adjusted so that it is somewhat greater than the diameter of the pipes.
  • the jacks 14 are not under pressure and the struts 8 occupy a more inclined position relative to the vertical than in FIG. 1, under the action of the springs 17.
  • the soles 13 and the arch 21 are not in contact with the internal face of the pipe 1.
  • the pump 32 is then maneuvered to send, using the distributor 31, pressurized oil into the jacks 14, the piston rod 15 of which thus emerges from the cylinder.
  • the flanges 13, on the one hand, and the arch 21, on the other hand, are supported at two more or less diametrically opposite points against the internal face of the hose 1, which blocks the device relative to the pipe 1, the vault 21 projecting beyond the female end piece 37 over part of its length,
  • the pipe 2 is then brought, suspended for example from a sling, its male end 38 being turned towards the female end 37 of the pipe 1, from the top and from the right in FIG. 1, in line with the pipe 1, so that the upper part of its male end 38 comes to bear by its internal face on the vault 21.
  • the piston rod 28 of the jack 26 is attached to the eye 29 one end of a cable 40, the other end of which is subject to a counter-support element 41, for example a plank or an iron bar, placed crosswise in the collar of the female end 37 of the pipe 2.
  • the person operating the device is in the immediate vicinity of the fitting area of the two pipes and can therefore, on his own, perfectly monitor the fitting operation.
  • This person can, preferably, enter the pipe to be laid as soon as the latter has, for example, descended into the excavation and is nearby above the bottom of the latter. It then always remains inside the pipe to be laid, therefore protected from any risk of the excavation falling.
  • a possible fall of the pipe to be laid would not from this moment, no more unfortunate consequence since the fall height would be low and the person inside the pipe could support it without any damage. For this reason, it even becomes possible to lay such pipes using hydraulic equipment. This is forbidden until now due to the compulsory presence of workers in the excavation, below the pipe to be laid, to guide the latter during nesting, which always implies the use of a first machine by hydraulic example to dig the excavation and a second mechanical machine to lower the pipe into the excavation.
  • the apparatus according to the invention is designed so as to leave the center of the pipes free to allow the passage of a laser beam used as a guide means for laying pipes composed of nested pipes.
