|The innovative CeTeau Vacuo is designed to accelerate the consolidation for soft and very soft saturated fine- grained soils.
The system consists of installing prefabricated vertical drains, individually connected below the surface to vacuum transmission pipes. These pipes are than connected at surface level to a horizontal tubing system by means of specially developed airtight T-couplings. The so-called drainage screens, a row of vertical drains that are connected at the top to a horizontal line, are brought outside the surcharge (if any) and connected to a combined vacuum air pump that has been developed in-house.
The advantage of this method over the traditional sealing by geo-membrane is that leaks are fully traceable even after surcharge loading.
This loading process creates an accelerated isotropic consolidation in the soil mass in a relatively short time, eliminating the need for long-term and potentially unstable surcharge loads. The system is applicable in under the following conditions; Stability problems, No space for shallow slopes or berms, minimal allowable deformation of subsoil ( close to buildings) or Short construction time available.
