US 8,944,184 B2 · Suspension extraction device

Abstract

The present invention concerns a device for proving the quality of a jet grouting body. Such a jet grouting body is produced by means of a drilling and grouting linkage assembly. An extraction device according to the invention for extracting a suspension from such a jet grouting body comprises: a first segment with a cavity comprising a fluid, in particular a liquid, in which a first chamber is provided, the volume of which can be modified and which is connected with an opening for extracting a specimen, and a further segment which is intended to receive the fluid from the cavity. By receiving the fluid in the further segment, the volume of the first chamber can be enlarged; furthermore the extraction device can be integrated in a drilling and grouting linkage assembly.
