Method for mounting nozzle jet floor, involves lifting nozzle jet lance with part of holes in bore hole up to depth, and bringing column to form reinforcer, where column is vertically arranged at distance from nozzle jet floor

摘要

The method involves introducing a nozzle jet lance into a hole up to a given depth into a substrate (2). A hardening medium is injected into the depth in the substrate to form a distance column (4) based on a nozzle jet process. The introduction of the lance and the injection of the medium for holes are repeated to form a closed nozzle jet floor (1) formed by the column. The lance is lifted with a part of the latter holes in a bore hole up to another depth. Another column is brought to form a reinforcer (3), where the latter column is vertically arranged at a distance from the floor.
