Forming compression anchor with tensile member (5), anchor head, and compression body

摘要

The compression anchor consists of a tensile member, an anchor head and a compression body (8) and its formation starts with sinking a borehole in the ground, into which the tensile member is located. In order to form the compression body, a binding injection material is injected into the lower region of the borehole.The binding material is injected under pressure of 100-700 bar. The borehole surrounding ground is cut-up to form drilling debris, with which the injecting material is mixed. The injecting is carried out by a high pressure injection linkage (5) with lower end outlet nozzle.
