Digital scale drainage boards, also known as plastic drainage strips, come in various shapes such as wavy and harmonica. The center features an extruded plastic core board, which serves as the framework and conduit of the drainage strip, with a cross-section in parallel. Both sides are wrapped with non-woven geotextile as a filter layer. The core strip supports the structure and channels water from the filter layer upwards, providing an excellent vertical passage for soft soil treatment using drainage consolidation methods, such as silt, cohesive soil, and fill soil. It shortens the consolidation time of soft soil. Bagged sand wells are long bags filled with permeable geotextile and sand-gravel, placed in soft soil foundations to form drainage sand columns, accelerating the consolidation of soft soil. The bagged sand well machine with and without a gate frame uses two different types of machinery. When constructing bagged sand wells for soft soil foundations, the processes differ.
