Method for lining boreholes for deep bores and device for carrying out said method

Abstract

The invention relates to a method for lining boreholes for deep bores. A lining method, which makes a rapid process sequence possible with a substantially uniform borehole diameter, is characterized, according to the invention, in that the borehole is lined directly after boring with a hybrid material consisting of a fibrous material and a hardenable medium. The invention also relates to a device for carrying out the method.

1 . A method for lining boreholes for deep bores, characterized in that the borehole is lined directly after drilling with a hybrid material consisting of a fiber material and a curable medium. 
     
     
         2 . The method as claimed in  claim 1 , characterized in that the wall of the borehole is continuously lined. 
     
     
         3 . The method as claimed in  claim 1 , characterized in that the curable medium is sprayed onto the fiber material. 
     
     
         4 . The method as claimed in  claim 1 , characterized in that the hybrid material can be applied onto the borehole wall in one layer or in multiple layers. 
     
     
         5 . An apparatus for carrying out the method as claimed in  claim 1 , characterized by a borehole lining module which has spray nozzles for applying a curing medium, and a reinforcing fabric laying apparatus. 
     
     
         6 . The apparatus as claimed in  claim 5 , characterized in that the borehole lining module is connected to supply devices outside the borehole via flexible pipe and/or hose lines, wherein the pipe and/or hose lines serve for the supply and removal of the materials relating at least to the borehole lining module and for the feeding in of the electric supply lines. 
     
     
         7 . The apparatus as claimed in  claim 5 , characterized in that at least the borehole lining module is connected to a workplace outside the borehole via data lines, for example a bus system. 
     
     
         8 . The apparatus as claimed in  claim 7 , characterized in that, via the data lines, in addition to the system parameters, such as, for example, feed speed, all of the ambient parameters in the borehole, such as, for example, temperature, pressure, rock density and the like, can be determined via sensors coupled to the data lines and can be transmitted to the workplace in order to control the borehole lining module.
