Document Type and Number:
WIPO Patent Application WO/2014/111104
Kind Code:
A3
Abstract:
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).
