Original Abstract

Repeated problem in foundation of the pylon of bridge structure is the unstable subsoil with low bearing capacity. The stabilization of subsoil by grouting mixtures, in places where the original subsoil does not have the demanded bearing capacity is a technology known already for more decades. It concerns the pumping process of liquid with changeable viscosity into the soil, into disintegrated soil or concrete with the aim to decrease the permeability. Clay-cement or purely cement suspensions were formerly used for this purpose. However this methods do not meet sufficiently the requirements of todays building industry. The endeavour or trend of the last years is the utilization of economically not demanding waste materials. This is the advantageous utilization of these materials exactly into grouting mixtures for the stabilization of subsoil or for filling of bulk caverns. The basic condition to prepare grouting and filling materials of quality is the viscosity of this material. The viscous grouting and filling material should fill in or fill around the structure or element to establish a block against liquids or vapours. It is further of great importance to enable the escape of air and to prevent the formation of air pockets. The most suitable way of the solution of these problems with foundation of the pylon of bridge structure is technology of soil stabilization - grouting systems.
