Trial works on soil consolidation before tunnel construction

This paper describes the results of the trial workd conducted in a test area, which is a part of Krasnopresnensky prospect including an automobile tunnel combined with one of the metro lines that are being built in Moscow. The objective of these works was to detemine the technological regularity of soil consolidation before inter-tunnel connections are friven. Basics of the injection technology were checked in the laboratory. From the results, the composition and penetrating capacity of the injected micro-cement grout suspension were determinated. The injection and control works in the test area have indicated that the ground may be successfully fixed by appying a manchette injection method of micro-cement-based grout.
