Adaptability It can be adapted to all types of buildings, retaining walls, and structures for various uses. The improvement diameters range widely from φ400 to φ1200mm. The design strength can be set within the range of Fc=400 to 1500kN/m2. Construction machinery and plants can be selected from small to large sizes depending on site conditions. In some cases, administrative agencies may relax design conditions such as the allowable stress of the improved ground and the upper limit of improvement length. Low Cost Depending on the ground conditions, it may be possible to support at shallower depths than pile foundations. The quality control surcharge factor is small, which helps to minimize excessive material usage. By adopting "Inspection Method A," quality inspections can be conducted at minimal cost. Proper selection of improvement diameter can lead to shortened construction periods and cost reductions.

Cross Swing Column Method

Benefits of Applying to Small-Scale Buildings, etc. The Cross-Wing Column Method has been recognized, as a result of numerous tests, to allow for the relaxation of quality control in small-scale buildings, as follows. This enables significant reductions in the costs associated with quality control, even though it is a method that obtains performance certification. Please refer to the standard specifications table for the conditions applicable to small-scale buildings. Mix design tests can be omitted. Quality inspections can be conducted using mold cores.
