摘要： The invention relates to a boring and laying device for trenchless pipe laying, comprising a boring head for loosening the rock, said boring head having a connection for a pilot bore linkage; a pump for suctioning and discharging debris loosened by the boring head; a transport portion behind the boring head, at least one suction element being provided in said transport portion for receiving and discharging the loosened rock; and a connecting portion which has a connection for the pipeline. The invention also relates to a boring and laying method for trenchless pipe laying, wherein a pilot boring process is carried out from a starting point to a destination along a specified boring line. The pilot boring process is carried out by advancing a pilot boring head with a pilot bore linkage, a boring and laying head being connected to an end of the pilot bore linkage after reaching the destination. The boring and laying head is connected to the pipeline and is used to expand the borehole, and simultaneously the pipeline is laid by retracting the pilot bore linkage from the borehole at one side and/or by inserting the pipeline into the borehole. Debris loosened by the boring head is hydraulically received behind the boring head of the boring and laying device and is discharged from the borehole by means of a pump.

摘要： The invention relates to a device for conveying away drillings removed by a drilling tool (113) during the creation of a drill hole (101, 102) for laying a pipeline, said device having at least one pump (12) for pumping away a drilling liquid mixed with the drillings and at least one receiving body (11) with at least one receiving chamber (17), which is connected via openings (14) to a drillings region (117) behind the drilling tool (113). The problem addressed by the invention is therefore to create a device for conveying away drillings, with which it is possible reliably to transport away the drillings via a pressure conveying system. According to the solution of the invention, a receiving element (13) for mechanically receiving the drillings is provided on the receiving body (11), on which receiving element at least some of the openings (14) are arranged, via which the drillings reach the receiving chamber (17).
