DE4404830A1 - Universal trench construction and shoring machine - Google Patents

Abstract

The machine has a main frame (1), with two guides for the shoring panels (2). The panels are vertically movable. Two driven shafts (12) have couplings (14) and gears (13). The gears mesh with racks (2.1) on the shoring panels. Shafts and gears may vibrate.An expander frame (4) may execute the support function of the main frame. It is vertically adjustable via cables and winches (17). A tilting device (3) for the shafts permits the gears to be released. A vibrator (5) is located on an arm, which is connected to the main frame. There is also a sand container. A trench digging machine (11) is also part of the unit.

Description

The invention relates to a continuously progressing Digging and digging implement, which in combination the Digging and supporting the trench, formed from a drive clear, torsionally rigid main frame, which is above the excavation pit can be positioned. The one on the main frame movable arranged excavator starts digging the trench. Here the shoring panels in this area are shown below mechanism described lowered. To those on the shoring racks arranged on the grips on the shaft sensitive slow rotating gear and pushes with the force from the torque down the shoring panel. This work can also of hydraulic cylinders with tabs on the Ver construction boards are taken over. About the couplings Controlled panel drive so that each panel is individually can be pressed. Repressing and dredging takes place until the required trench depth and length is enough.

The work in the trench (pipeline, cable, etc.) can now be done.

The boards can now be raised again in the filled area. The excavator pulls several panels out of the frame construction and reinserts them at the front in the working direction. The shoring panels are now very firmly attached to the main frame ( 1 ) due to the forces from earth pressure. Next, the expansion frame ( 4 ) is lowered to the required depth and relieves the main frame due to its spreading against the shoring panels ( 2 ).

The shafts and gears are removed using the folding device the racks of the sheeting panels and the whole Shoring device can now move forward by one or two shoring widths move. Now the waves fold back into their original position.

The process can now start again.

Significant advantages:

• - Low personnel costs
• - Low vibration  
• - Avoid obstacles
• - high security standard
• - Optionally equipped with caterpillar tracks drive or wheels
• - continuous work including ver seal in the pipe trench

Claims (1)

1. Trench sheeting device for excavating trenches using the cycle method, consisting of a main frame ( 1 ), an excavator ( 11 ) and a finite number of shoring panels ( 2 ), an expansion frame ( 4 ), 2 shafts ( 12 ) with couplings ( 15 ) and gear wheels ( 13 ) and racks ( 2.1. ) on the shoring panels, a folding device ( 3 ) for the shafts, a vibrating device ( 5 ), a storage container ( 7 ), axles with wheels ( 9 ) and auxiliary shoring panels ( 10 ), characterized by the following features:

• 1.1. There is a main frame ( 1 ) which has 2 guides over the entire length, in which the shoring panels ( 2 ) and ( 2.1. ) Are guided. The shoring panels ( 2 ) and ( 2.1. ) Can be moved vertically.
• 1.2. There are 2 disengageable driven shafts ( 12 ), which are provided with couplings ( 14 ) and gears ( 13 ). The gears engage in the racks ( 2.1. ) Of the shoring panels. The waves can also vibrate together with the gears.
• 1.3. There is a finite number of sheeting panels ( 2 ) which are provided with racks ( 2.1 ) on the inside.
• 1.4. There is a spreading frame ( 4 ), which takes over the supporting function of the main frame. The spreading frame can be adjusted vertically using ropes and winches ( 17 ).
• 1.5. There is a folding device ( 3 ) for the shafts so that the gears can be disengaged.
• 1.6. There is a vibrating device ( 5 ) which is connected to an automatic auxiliary boom. The auxiliary boom is connected to the main frame.
• 1.7. There is a sand reservoir ( 7 ) for filling the trench.
• 1.8. There are wheels and axles ( 9 ) on the front and rear of the main frame. All axes are adjustable in height.
• 1.9. There are auxiliary sheeting panels ( 10 ) that can be installed below and above the obstacles.
• 1.10. There is a digging device ( 11 ) which takes out the shoring panels that become free at the back and puts them back in the front. The digging device also takes over the necessary excavation work with a backhoe ( 16 )
• 1.11. There is a sliding guide ( 15 ) for the digging device.
• 1.12. There is a water drainage system permanently installed in the device ( 8 ).
• 1.13. There are several hydraulic cylinders ( 6 ) that pull the building boards ( 2 ) and ( 2.2. ) Up and down. This drive is optional.
