Combined tunnel or shaft drilling machine with simultaneous locking and stiffening of the shaft tunnel and return transport of the excavation material.

The! Combinations he invention relates to a machine by means of which tunnels or shafts without first tearing open the Abräur.unaterials (earth, rock, etc.) except for the approach of the hole - drilled in a work passage, boarded, stiffened with 3eton, cast or other building material and at the same time the excavated material (soil, rock ac.) is fed out during the drilling of the tunnels are plastic sealed.

The! Conventionalle way of making tunnels or shafts consists in tearing up the earth, propping it up and then turning on the tunnel or shaft and filled with liquid or plastic, later hardening building materials, then switch off again and the resulting cavities are filled with filling material and compacted.

The procedures known so far are pronounced time consuming, with high labor costs and by the respective cordoning off of the boating sector with traffic obstructions and considerable inconvenience (Noise pollution etc.) for road users and residents.

According to previously known methods also related formwork material can be rarely used again ..

The material and wage costs that were previously known to be applied are disregarded after cumbersome procedures of considerable noise pollution and traffic obstructions for residents and road users - In addition to the long construction times that have to be accepted, this is of considerable importance. The environmental pollution is also the same as before Procedure extraordinarily high.

The combination invention is based on the task of a combined tunnel or shaft boring machine with simultaneous boarding and stiffening of the shaft tunnel as well as return transport of the excavated material to propose the disadvantages of the previously known methods listed above removed, disabilities etc. prevented and limited to a minimum.

This eliminates:

Blocking off whole '.fohnsciete for traffic Tearing up the existing road surface, Consumption of considerable formwork material, so far high noise pollution and Environmental pollution and, at the same time, the enormous wage costs incurred so far.

This object is achieved according to the invention by dciß the combined machine a windmill-wing type Carrying an Abraunikopf, which breaks down the existing material

and at the same time transported into the funnel under the tube shaft on the conveyor belt below.

In doing so, the overburden head, which is directly located behind the actual drill, also be constructed in such a way that the tunnel or shaft each is almost angular and is only slightly rounded.

The stiffeners of each with hard materials coated clearing sheets are designed so that when drilling and clearing the material this directly reaches the conveyor belt via the funnel.

O ^v

The hard material coated drill to which the first clearing flight follows, again by one at least 2 m long, supporting shaft.

Then there are the second ones firmly mounted on the same shaft - at least the one 2/3 diameter of the first clearing wing exceeding the clearing wing with the actual. Tunnel diameter as well as stiffeners that are attached in such a way that the waste material on the .under the './eile running Conveyor belt arrives.

At the far end of the Uelle there is a bearing with housing.

On the same square, but in front immediately behind the stiffening of the clearing head are at least three hydraulic cylinders - individually controllable but ultimately coordinated with one another - the in turn, on firmly welded. Steel rail run, mounted.

The drilling and clearing head in controlled in the desired direction.

The hammer drill attached to the end of the skin can be driven with compressed air or electrically.

Between the clearing head and the steel ring behind it, there are several plastic injection nozzles or Welding equipment attached after the removal of the excavated material by applying a plastic filament Prevents the remaining material from crumbling after drilling and clearing.

The steel ring itself contains several nozzles on its front, to which in turn a flexible nozzle Hose is connected, by means of pressure more fluid or plastic, at least later hard the building material to be pressed and at the same time together with the hammer drill the whole combination with drives forward.

Thanks to the flexible ones connected to building material pumps Hoses and the nozzles, which in turn are seated on the steel ring, are controlled depending on the change in direction via hydraulic cylinder - more or less building material pressed in.

The steel ring with its outer and inner plastic spray nozzles and building material connection pieces must have a ball joint on the same shaft and strong springs between the clearing head and ball joint and bracket of the bearing, on dam. the hydraulic cylinders are mounted, are stiffened in such a way that indirectly the pressure of the building material pumps the forward movement of the combined machine.

The one needed to stiffen the tunnel The building material is made of small rollers, which the inner plastic cladding presses over the entire circumference of the tunnel until the building material has hardened distributed.

A welding device is used to pass through the steel ring one of the at least three necessary steel rails directly at the rear end of the steel ring welded onto which the rollers of the hydraulic cylinders run, which in turn immediately behind the .Stiffening on the above-mentioned camp are appropriate.

Icings and Cu rails are continuously connected to the hydraulic cylinders with the drilled Tuxaiel.

These rails must have a certain length with ball joints lengthways and crossways to make it possible a change of direction through small knobs with a spring holder on the rails.
