The invention relates to mining and construction and can be used in devices for automatic control of the position of the tunnel complexes used, for example, in the construction of tunnels and reservoirs for various purposes.

You know the automatic position control is passed to the sliding rods. /Cm. for example, USSR author's certificate 135050, CL E 21 D 1/00, published. 1961/.

The disadvantage of this device is that it is inaccurate, cumbersome and cannot be used, for example, in shield tunneling complexes used in the construction of tunnels.

It is also known a device for automatic control of the position of the shield tunnel complex, which includes placed at the rear of the complex unit direction of penetration in the form of a source light beam; fixed to the body of the shield visor objective with built-in image sensor controlling the position of the shield, the optical axis of which is in the initial position colinear with the target goal, and automatic processing of information about the location of the complex and its delivery to the operator. /Cm., for example, SU 949188, CL E 21 D 9/06, 07.08.1982/.

The main disadvantage of the known device is the fact that the image sensor with a complex and delicate optics placed on the movable part of the tunnel system in a very limited space and therefore requires additional safeguards it from damage, as well as additional power cable with connection equipment, stackable progresses complex in the items during the construction of tunnels and pipelines of small diameter.

In addition, the placement of the image sensor on the movable part of the tunnel complex due to the presence in the source control system beam /for example, laser/, which serves as a knob direction of penetration and requires additional energy costs.

The closest solution to the proposed technical essence and the achieved result is the automatic control of the position of the tunnel complex including unit areas penetrations in the form of a theodolite placed in front of and behind the tunnel complex targets, the video probe control static state of the complex and automated processing of information about the location of the complex and its delivery to the operator, electrically connected with the image sensor (see, for example, DE 4017833, CL E 21 D 9/06, 06.02.1992/.

The disadvantage of this device should include the fact that it cannot be applied for the rapid and continuous monitoring provisions in the dynamics of the head part of the tunnel complex.

Object of the present invention is to provide such a device which obviates the aforementioned disadvantage of the known device and automatic control of the position of the tunnel complex including unit areas penetrations in the form of a theodolite mounted on the casing of the tunnel complex sighting target, image sensor and automatic processing of information about the location of the complex is electrically connected with the image sensor, the latter performed with a position-sensitive matrix and embedded in theodolite and target the purpose of the led is placed through the transverse plate in a plane perpendicular to the longitudinal axis of the housing of the tunnel complex and symmetrically relative to the axis, with the optical axis of the image sensor in the initial position of the tunnel complex colinear with the target goal.

The invention is illustrated in the drawing, where

in Fig. 1 - shows a General schematic view of the tunnel complex in longitudinal section showing the device of the present invention in position after installation of the initial section of the tunnel

a in Fig.2 is a view along arrow a in Fig.1, schematically depicting the sighting target placed on it by the LEDs.

The device is mounted on the shield tunnel complex, containing the head part 1 of the shield, swivel relative to the direction of penetration /project tracks the tone of the ITA have the possibility of longitudinal displacement relative to each other due to the presence of a telescopic connection and power cylinders 4 between them. As shown in Fig. 1, the shield abuts the rear face to the front face of the lining 5 of the tunnel. The rear end of the tunnel lining apart in a pressure cooker 6 jacking station 7, located in the starting pit 8.

The device controlling the position of the tunnel complex contains the referencing direction of penetration 9 installed in the starting pit 8 and made in the form of a standard theodolite equipped with a video probe 10 with a position-sensitive matrix CCD/. On the housing head part of the shield 1, and more precisely in the recess walls secured /in this case still/ target the purpose of containing the LEDs 11, placed on a strap 12 in the plane perpendicular to the longitudinal axis of the warhead 1 shield and symmetrically to the axis. In this case, the number of LEDs is three. In the initial position of the sector, i.e., when the longitudinal axis of the shield matches the slope of the tunnel/ center targets set on the optical axis of the image sensor 10 /kulinarne/.

For information about the location of the complex in space and delivery of this information to the operator on ground-based equipment 13, the device is equipped with an automatic processing of the position information kolihalova cable 14 with the image sensor 10.

The device operates as follows.

Design and direction of penetration asked by theodolite 9.

In the initial position of the complex target purpose /11, 12/ by hydraulic cylinders 4 set colinear with the optical axis of the image sensor 10.

After advancing the head part 1 of the shield in the direction of drilling using hydraulic cylinders 4 probable lateral, vertical, torsional or combined reject her from the predetermined route. As a result of these deviations is offset targets /11, 12/ with deviations of the LEDs 11 from its original position. The amount and nature of these deviations are recorded CCD video probe 10, the signals from which are received in an automatic system for further processing according to the programs that implement the algorithms for the calculation of certain offsets, and outputting to the monitor the operator of the received data. After that, the operator carries out the usual steps for the future operation of the tunnel system.

Thus, by posting the video probe in free and fixed area subject to the fulfillment of targets of LEDs and combining the image sensor with theodolite, directional drilling, it has become possible DOS is reducing production and operating costs.

According to the applicants present technical solution meets the criteria of the invention "novelty" because the analysis of the information available in the scientific and patent literature on the subject, showed no mention of known technical solutions, similar declared by a combination of traits listed in the claims. The claimed technical solution also meets the criteria of the invention "significant differences" because the exclusion or replacement of any of the distinguishing characteristics of the invention will lead to the impossibility of achieving applicants purpose.
