Definitions

  • Apparatus for excavating trenches includes a pair of vertical piles each having a guide rib thereon, adapted to be driven in parallel relation into the soil; a vertically movable chassis provided with upper and lower grooved guide rollers yieldably engaging the guide ribs; a grab bucket suspended below said chassis; cable means for suspending said chassis; outwardly divergent rails forming an upward extension of the guide ribs above the soil; scrapers on the chassis disposed adjacent each lower roller engaging their respective guide ribs; and brushes on the chassis disposed adjacent each upper roller engaging their respective guide ribs; the chassis, grab bucket, scrapers and brushes being all of same width as the trench which is excavated by the apparatus.
  • the present invention relates to a new apparatus for the digging of trenches, principally with a view to excavating deep narrow trenches intended for the placing of a wall embedded in the earth.
  • a method of excavating trenches comprises the steps of implanting two vertical piles in the soil each of these piles having a guide face on which there rolls an excavating machine formed by a chassis fitted with a bucket grab, and lowering the machine into the ground on the piles while operating the bucket grab.
  • the guiding of the machine is preferably ensured by flexibly mounted rollers on the chassis, hearing on opposing faces of the two piles.
  • FIGURE 1 is an assembly view illustrating two possible positions of a machine according to the invention
  • FIGURE 2 is a plan view of the machine shown in FIGURE 1, and
  • FIGURE 3 is an end view of the machine.
  • the first step is to implant vertically in the soil two concrete piles A of known type, which extend to the full depth desired for the trench.
  • Each of the piles A is preferably made with a cruciform shape and their opposing faces are furnished with a sheath of sheet metal 2 forming a roller rail of semicircular crosssection.
  • each pile A carries in the conventional manner one or more transverse holes 3 which are used to mount draw bolts 4, ensuring the fixing of a 3,466,769 Patented Sept. 16,, 1969 framework 5 on the top or the aforementioned piles A.
  • the framework 5 rests on the soil and it supports two rails 6 which diverge upwards and at their bases register with the sheet metal sheaths 2 of the piles A.
  • the rails 6 are arranged in the vertical plane which is fixed by the axes of the two piles A. These rails 6 are rigidly held at their tops by a frame 7.
  • the assembly of the rails 6 and the sheet metal sheaths 2 constitutes a metal roller-way 2-6, which is used to ensure the guiding of an excavating machine which will now be described in detail.
  • the excavating machine in question includes a chassis 8 which is suspended from a manipulating cable 9 of which the control is ensured from the exterior of the trench by any known means. These means may consist of a winch, a crane or any contracting machine whatever.
  • the chassis 8 is provided with four guide rollers arranged in symmetrical pairs on each side of its vertical axis, that is to say, two upper rollers 10 and two lower rollers 11. Each roller 10 or 11 is mounted free in a supporting fork 12 which is attached to a stem 13 able to slide horizontally against a compression spring 14 in a seating provided for it in the chassis 8.
  • Each roller 10 or 11 has a groove 15 (FIGURE 3) with a profile of the arc of a circle which allows it to run along the rails '6 or the sheet metal guides 2.
  • the assembly is of dimensions such that the springs 14 are always compressed when the machine is placed between two piles A on which it rolls on its rollers 10 and 11 (FIGURE 1).
  • each lower roller 11 There is provided below each lower roller 11, a metal shoe 16 of which the tip is shaped exactly to fit the external contour of the corresponding roller-way 2-6, which it thus scrapes so as to remove from it any grit or deposits which may harm the smoothness of rolling. Similarly, there is placed immediately below each upper roller 10, a metal brush 17 intended to complete the cleaning of the appropriate roller-way 2-6.
  • a hydro-electric bucket grab 18 of known type, of which the automatic or semi-automatic action is controlled from the outside.
  • This bracket 18 principally includes two jaws 19 jointed about transverse spindles 20.
  • chassis 8 of the machine is suspended from the cable 9 by means of a block 21 which may be aligned in any required direction in relation to the chassis 8 then locked in any position whatever.
  • the machine When the chassis 8 is lowered into the position 801 shown in FIGURE 1, the machine begins to come into contact with the rails 6 by its lower rollers 11 which contract in the direction opposite to that of the arrows 22.
  • the upper rollers 10 When the machine is further lowered, the upper rollers 10 enter in their turn into contact with the rails 6, then in proportion as the level of the soil is approached, the various springs 14 are compressed finally to hold the rollers firmly applied against the sheet metal sheaths 2 when the machine is engaged between the piles A.
  • the bucket grab 18 When the jaws 19 come into contact with the soil, the bucket grab 18 is operated in the usual manner so as to take a load of earth which is then raised by means of the cable 9 before tipping it out of the trench.
  • the shoes 16 and the metal brushes 17 are given a width equal to that of the jaws 19 of the bucket grab (FIGURE 3).
  • piles A are shown extending to the full depth of the trench to be excavated, it should be understood that it may in some instances be suflicient to arrange them deep enough to allow the rollers 11 to descend enough to allow the grabs 19 to cut out the required depth.
  • Apparatus for excavating trenches comprising a pair of vertical piles each having a guide rib thereon, adapted to be driven in parallel relation into the soil; a vertically movable chassis provided with upper and lower grooved guide rollers yieldably engaging said guide ribs; a grab bucket suspended below said chassis; cable means for suspending said chassis; outwardly divergent rails forming 4 an upward extension of the guide ribs above the soil; scrapers on the chassis disposed adjacent each lower roller engaging their respective guide rib; and brushes on the chassis disposed adjacent each upper roller engaging their respective guide ribs; the chassis, grab bucket, scrapers, and brushes being of same width as the trench which is excavated by the apparatus.
