Definitions

  • the invention relates to a slot device for the production of slots, z.E. for the production of diaphragm walls, duct installation and cable laying and a method for the production of slits.
  • the invention is based on the object of producing slots more cheaply and with a vertical termination at the end and at the beginning and deeper than is possible with previously known trenchers and cable plows.
  • This object is achieved by the slitting device according to claims 1 and 2 and by the production method according to claim 3.
  • the essentials of the invention in claim 1 are the slitting knives. These consist of a cutting edge at the front with an angle of attack in the direction of advance of the machine and in the running direction of the chain, a plate attached to the back of the chain, which closes the slot to be digged to the rear and thus prevents the floor from falling out and another plate that between the cutting edge and the back plate closes the slot down and transports the bottom up.
  • the main advantage of the device and method according to the invention is that it can be used to produce slots much more quickly and inexpensively, in particular deeper slots than with all previously known methods.
  • the reason for this, in comparison to the diaphragm wall grab and backhoe excavator, is the continuous operation of the device according to the invention and, compared to the auger milling machine, in the much greater performance of a chain milling machine.
  • the advantage of the device according to the invention lies in the possibility of milling or displacing vertically into the ground and bring the boom vertically out of the ground. The slope at the beginning and at the end of a trench, which inevitably occurs with conventional trenchers, is eliminated.
  • the slot closes again because the soil pressed into the side of the trench penetrates back into the slot. This means that after a cable, a water pipe or the shoring elements have been inserted, the trench does not need to be filled again. With the displacement wedges attached to a chain, much deeper slots can be made than with cable plows.
  • the tiltability of the device in relation to the carrier device allows use even on uneven floors.
  • the rotatability of the device allows the use of this device even where the slot has to be excavated next to side obstacles.
  • a great advantage lies in the fact that this device can be used not only as an independent self-propelled device in which the carrier device and slot device form a unit, but also as an inexpensive attachment, which makes the slot method according to the invention even more cost-effective due to the lower capital expenditure.
  • Be Particularly advantageous for the production of diaphragm walls or shoring is the attachment of the slot device to leader equipment of excavators, since this attachment enables the driver to lower the slot device vertically without great effort.
  • the side guide surfaces have the advantage that the running of the chain is stabilized and the chain is prevented from evading.
  • the deflector plates attached to the side of the slot device or holder promote the loosened floor to the side and prevent the floor from falling back into the slot.
  • a snail can also be attached if there is a large amount of soil, which conveys the soil to the side. Concrete or betonite can be introduced through a pipe attached to the device.
  • an insertion device for inserting shoring elements By attaching an insertion device for inserting shoring elements to the device, the slot device can be used for trench construction work.
  • the advantage of this combination of slot device and shoring device lies in the much higher shoring speed compared to all shoring methods previously available.
  • the slot device with the inserting device for shoring elements is attached to the leader of a 20 t excavator, then with a depth of the heart-digging trench of 3 m and thus also a slot depth of 3 m, a slot speed with medium soil of 100 to 120 m / h reached. If only 50% of this performance is considered as practical work, the performance of the slot device with the shoring device is four to five times greater than with all previous shoring methods. Instead of about 50 to 60 m daily output, a daily output of approx. 240 m on both sides is achieved.
  • sealing sheet rolling device which can be constructed, for example, so that the roller with the sealing sheets is horizontally attached above the slot and runs over a roller that is attached in the slot at a 45 degree angle
  • sealing work can be carried out extremely inexpensively.
  • Such sealing work are necessary, for example, when sealing the incoming Gruridrasser or on the slopes of canals and river courses to prevent water from penetrating.
  • cables can be laid simultaneously with the slot production.
  • the device is held on a carrier device or its extension arm (1) by a mounting frame (2).
  • the device consists of an extension arm (3) around which the chain (4) with slot knives (5) runs.
  • the cutting edge of this slitting knife has an angle of attack (11) both in the chain running direction and in the direction of the advance of the device.
  • the slitting knife is provided with a plate (12) covering the slot to the rear and also with a plate covering downwards, which is bevelled on two sides (FIGS. 2, 13) or on one side (FIGS. 4, 13) against the Chain runner tung.
  • the cutting edge (11) can either be as long as shown in Fig. 5 No. 11, or short, so that the bottom can fall out below the cutting edge.
  • Guide surfaces (14) are attached to the slitting knives (5) on the side.
  • Height-adjustable deflectors and baffles (15) are attached to the holder (6), which is attached to the boom, on the side of the slot device (3).
  • the guide and deflector plates (15) can be adjusted in height in relation to the slot device (3) and can be fixed by means of known devices such as a row of screw holes ( 1 6) one above the other on the slot device bracket or holder (6).
  • a tilting device (17) is installed between the carrier device and the slot device (3).
  • a rotating device (18) is attached between the holder (2) of the device and the carrier device.
  • a pipe with a separating plate (22) is attached to the holder (6) behind the boom with chain and knives, in order to fill support liquid into the slot, for example in the form of concrete.
  • the insertion device for shoring elements (7) with the guide rails (8) can be attached to the holder (6) or the unwinding devices for sealing sheets or a cable laying device.
