Definitions

  • the present invention relates to a device for removing cuttings when making trenches or excavation of great depth.
  • a solution consists in interrupting the drilling to lengthen by adding a new element the pipe which is used for the evacuation of the cuttings.
  • This solution has the drawback of requiring work to be interrupted, which constitutes a significant loss of time and money, given the immobilization of very expensive equipment which is necessary for this type of work.
  • the present invention relates to a device which makes it possible to dig trenches or excavations of great depth using a lifting device whose height is only a fraction of the depth of the trench and without it it is necessary to interrupt drilling to modify the structure of the device which allows the removal of cuttings.
  • the subject of the present invention is a device for the evacuation of cuttings resulting from the drilling of a trench or an excavation under mud at a great depth, characterized by the fact that the cuttings evacuation pipe comprises a first lower section arranged in the vicinity of the drilling cutters, which is constituted by a telescopic tube and a second section constituted by a flexible tube connected to the first section by one of its ends and the other end of which terminates in the vicinity of the ground at the point of unloading the spoil , this second section being supported between its two ends by a pulley which is suspended from the upper part of the lifting machine, and the height of which can be modified during work.
  • a blocking device which allows the two elements of the telescopic tube to be joined, in particular in the position where these two elements are inserted into one another.
  • the second flexible section of pipe is supported by a pulley itself suspended from a cable descending from the top of the lifting device which is wound on a winch preferably exerting a constant force .
  • the flexible section of the pipeline automatically adapts to the configuration of the device which varies with the descent of the cutters into the ground.
  • the upper part of the female element of the telescopic tube as well as the upper part of the male element of this tube are held in vertical position by means of guide glasses of which they are integral and which are crossed by a cable which supports the milling machine during its work.
  • the device according to the invention makes it possible for example, using a lifting device which has a total height of approximately 50 meters, to dig excavations the depth of which can reach approximately 140 meters without it being necessary to modify the structure of the device when lowering the cutter into the trench.
  • the device according to the invention can be implemented in different ways.
  • the two elements of the telescopic tube are tucked into each other and are locked on each other so that the telescopic tube does not stretch under the action of the discharge pressure of the cuttings, while the pulley supporting the flexible section is raised to the top of the lifting machine.
  • the pulley is then gradually lowered as the drilling progresses so that the telescopic tube, the two elements of which are tucked into each other, sinks into the ground as the cutter descends and this until the top of the telescopic tube reaches ground level.
  • the cutter can continue to descend, while the two telescopic tube elements gradually move away from each other until their maximum.
  • milling machine 4 which is intended to dig in the ground the trench 5 while being suspended at the top of the crane by one or more cables not shown.
  • the cutters are driven in rotation using electric or hydraulic motors which are supplied from the crane or from a power unit by pipes not shown.
  • the evacuation of drill cuttings mixed with the mud of the trench is carried out according to the invention by a pipe which comprises a first telescopic section 6 constituted by a female element 6 a inside which can slide a male element 6 b which itself constitutes a tube allowing the circulation of cuttings and mud.
  • a blocking device not shown makes it possible to immobilize the element 6b with respect to element 6 a , in particular in the position where these two elements are completely tucked into each other, as seen in FIG. 1.
  • the flexible pipe section 7 is supported by a pulley 8 itself suspended from a cable 9 passing over a pulley 10 at the top of the mast 3 of the crane, so that from the ground, it is possible to move the pulley 8 as desired to raise or lower it relative to the top of the crane.
  • the other end of the cable 9 is connected to a winch which exerts on it a constant force which thus makes it possible automatically to adapt the position of the pulley 8 to the descent of the cutter .
  • the device according to the invention is shown in FIG. 1 in its highest position, the male element 6 b being retracted as far as possible in the female element 6 a of the telescopic section 6, and the pulley 8 being raised in its highest position in relation to the top of the crane.
  • the strawberries are located slightly above the ground.
  • the extent of the descent of the cutter 4 corresponds substantially to twice the height of the lifting machine plus the increase in length of the telescopic section 6 which corresponds to the maximum output of the element 6 b out of element 6 a .
  • FIGS. 2 to 5 show the different phases of using the device according to the invention.
  • FIG. 2 shows the device in its initial position for which the male element 6 b of the telescopic tube is completely retracted into the female element 6 a , the pulley 8 being brought back to the top of the lifting machine.
  • the cutters are located substantially at ground level, and the elements 6 a and 6 b are secured to each other by any device placed at the top of the telescopic tube.
  • the cable 9 which supports the pulley 8 is connected to a winch with constant torque so that the pulley 8 is subjected to a sufficient upward force to maintain the flexible section 7 of the pipeline while being able to follow the downward movement of strawberries which gradually sink into the ground by digging the trench.
  • the male 6 b engages by first stationary element in the trench followed by the lower end of the flexible tube section 7.
  • This device is useful first of all for guiding the male element 6 b when it is lifted from the female element 6 a and on the other hand also for holding the upper part of the female element 6 a in the event where the telescopic tube protrudes substantially above the chassis of the milling machine as is the case in the embodiment shown in Figure 1.
  • FIG. 6 shows the female element 6 a of the female telescopic tube 6 a in which the male element 6 b slides.
  • the upper part of the male element 6 b is connected to the end of the flexible pipe 7.
  • the telescopic tube can rise over a height of several tens of meters above the frame of the milling machine.
  • the flexible tube 7 is liable to be subjected to movements due to the pumping of the cuttings, it is understood that it is preferable to keep the upper part of the telescopic tube in alignment with its lower part.
  • this type of device comprises milling machines of considerable weight and which it is necessary to support using one or more cables which terminate at the top of the lifting machine and which by the traction exerted on them makes it possible to determine the bearing force on the ground of the milling machine.
  • this or these support cables are perfectly vertical and aligned with the milling machine.
  • a second arm 16 is fixed with a screw socket 17 on the upper part of the male element 6 b and is provided with a bezel 18 at the inside of which the cable passes 12.
