Tool for sinking wells when driving tunnels, galleries or similar structures

The subject of the invention is a tool with which when driving tunnels, galleries or similar structures wells can be sunk from the bottom of the tunnel or gallery tube.

When building tunnels or tunnels, the bottom of which is below the groundwater level and where the groundwater is with it If the well is to be lowered with the help of wells, it is particularly advantageous to start wells from the bottom of the tunnel or gallery to sink. This creates, in contrast to the commonly used drilling of the wells from the terrain surface, no disruptions to this, especially not in the traffic area, as long as tunnels or galleries are built under traffic roads.

In addition, when boring a tunnel, the depth between the surface of the terrain is determined from the outset by the tunnel or Stoilen tube and tunnel floor saved in drilling depth.

Another advantage is that when drilling a well from the tunnel tube this takes place directly in the tunnel axis and not, as was the case with the drilling of the 'Selände surface from is unavoidable, sideways from Tunnel must be done.

The advantages outlined have the disadvantage that the working space in tunnels or galleries is narrow _. Underground drilling is less than drilling from the surface of the ground.

To drill wells from tunnels or galleries To make out more economical, drilling devices are known in which drilling columns are clamped in the tunnel on which drill heads, drill rods and drilling tools be guided. You have your own electrical, hydraulic or pneumatic drive units

In so far as all the individual parts of the drilling equipment are retracted separately, their construction is cumbersome and time-consuming. In order to avoid these disadvantages, drilling devices are known, in which all the individual elements, such as drilling column with drilling head, drilling tools and drive unit on one Chassis are mounted, which can be rail-bound or rail-less. These drilling jigs are closed before Moved to place and brought into drilling position. The disadvantage here is that the vehicle at the The narrowness of the tunnel or adit itself takes up a certain amount of space and thus further narrows the working space.

The aim of the invention is therefore to create a drilling device which in the case of tunnels or tunnels that are driven using a propulsion shield "in a simple manner Jacking shield can be attached and attached to their Drive to use the existing hydraulic system for propelling the shield, so that both on their own fairground as well as a separate drive system can be dispensed with.

This results in a particularly advantageous application of the invention if a dismantling and segment moving device is available in the jacking shield and the drilling device is combined with this will.

FIG. 1 shows a cross section through the 6th drive shield with a retracted drilling device.

Figure 2 shows a longitudinal section through the jacking shield with the excavation and segment moving device and the drilling device carried by this during the installation of a drilling tube *

According to the invention, the drilling device consists of a drilling frame (2), a 3-ear slide (3), a drill head (4) and the associated one Drilling tool (5).

To hang up a & s entire. Drilling device (1) in the dismantling and segment relocating device (6), holding devices (7) are attached to the side of the drilling frame (2).

The drilling rig (i) is laid as a whole with a Stollenhunt retracted-

The swivel arm (8) of the dismantling and segment moving device (6) reaches under the holding devices (7) attached to the drilling frame (2) and with their help lifts the entire drilling device (i) from the Stoilenirunt. While the drilling device (1) is being lifted by the dismantling and segmenting device (6), it is simultaneously set up and brought into the vertical working position.

The drilling carriage (3) slides upwards and in the drilling frame (2) down. This longitudinal movement is caused by a hydraulic working cylinder (9}> which one? at; upper latch of the drilling frame (2) and on the other hand on the latch of the drilling slide (3) is attached.
