Paralink combined with low-improvement DMM method.

Suppress overall deformation of the fill soil and achieve cost reduction with a low improvement rate! Examples of construction are also introduced with photos.

The "Low Improvement DMM Method" is a construction technique that places improved columns across the entire width in the transverse direction, which can suppress overall deformation of the embankment and allows for cost reduction by using a low improvement rate (by widening the spacing of the improved columns). When ground improvement is carried out at a low improvement rate, issues such as differential settlement between the improved and unimproved areas may arise, necessitating surface treatment as a countermeasure. For surface treatment, geosynthetics (Paralink) installation and shallow improvement methods are effective. [Selection of Geosynthetic (Paralink) Standards] ■ Determination of target differential settlement amount ■ -1 Calculation of proportional coefficient α ■ -2 Determination of tensile rigidity EA ■ Confirmation of tensile strength ■ Determination of required part numbers *For more details, please refer to the PDF materials or feel free to contact us.
