Would this work? What prevents the tube from collapsing?
The primary goal is to accelerate the consolidation of saturated, fine-grained soils like clays and silts. These soils hold water tightly, leading to instability and potential foundation issues.
Wick drains provide pathways for water to escape these soils.
The drains consist of a core that allows water flow, surrounded by a geotextile filter that prevents soil particles from clogging the drain.
By providing these drainage paths, water is drawn out, and the soil compresses, increasing its stability.Used in combination with pre-loading, or surcharging, wick drains (PVDs) evacuate pore water from soft, compressible soils to induce consolidation and settlement. This allows for expedited construction, which can begin in as little as one to three months as opposed to much longer wait times if wick drains are not used.The reduction of water content of the saturated layers allows the soils to better accommodate superimposed loads and minimizes future settlement. - Menard company
