Description

The mixed in place wall (MIP wall) consists of cylindrical overlapping columns, formed without casing where - when using the triple mixing tool - three intersecting piles are made simultaneously. The in situ soil is mechanically blended with a cement-based slurry. The result is a homogeneous mixed-in-place wall used for water cut-off and / or earth retention. Construction sequence Triple rod mixing installation process, in accordance with the requirements of standard prEN 14679: ‘Deep mixing” - Deep Soil Mixing or DSM (wet DMS method 1. In advance excavation of a guide trench approximately 0.5 m deep to accommodate the cement slurry during execution. Alignment of the triple mixing tool with the centreline of the wall. Commencement of the boring phase. 2. Throughout the descent, the auger-based triple mixing tool continues to rotate while self-hardening cement slurry is injected through the hollow stems of the central tubes, to the bottom of the augers. 3. The three mixing screws are driven by individual, however coupled rotary heads. Compared to the rotation direction of the inner auger, both outer augers rotate in opposite direction so as to mix the soil intensively with the binder grout.. 4. After reaching depth specified by the design, standard up to 14 m, the triple mixing tool is withdrawn under rotation and simultaneous injection of grout. With a thickness of 0.40 m and a width of 1 m, several intersecting panels are installed in order to form a homogeneous and continuous wall in the soil. 5. Insertion of the reinforcing elements, e.g. profiles.
