FOUNDATION SOLUTION WITH LOW IMPACT ON THE ENVIRONMENT

摘要

The paper deals with a new solution for realising foundations, having a lower impact on the environment than classical foundation solutions. The proposed solution consists of realising foundation holes punched with the help of a spherical tamper. A semi-spherical precast foundation or a monolith semi-spherical foundation will be introduced in the obtained hole. The spherical punching element cooperates better with the foundation ground leading to the uniform improvement both in depth and laterally wise of the foundation ground. The presented foundation is easy to realise and efficient. It aims at avoiding a more expensive and hard to realise indirect founding system needing special, high capacity equipment. That would block the respective location for a long time altering the environment. This solution for the realisation of foundation holes plays a great part in reducing the volume of digging and of materials used in the foundations, the quantities of materials needing transportation (soil, concrete, steel-concrete, wood for formworks, etc.) as well as the shortening of the construction period. All these factors have favourable impact on the environment, the investment costs being finally much smaller than in the case of other known solutions.
