What is a slurry trench

Upon reaching the appropriate hydration levels, confirmed by viscosity tests using a marsh funnel, the.Slurry wall construction is a technique used by civil engineers for building walls in those areas which are near rivers or oceans and for those places where the level of groundwater is high.The trench excavation is initially supported by either bentonite or polymer based slurries that prevents soil incursions into the excavated trench.The continuous diaphragm wall (also referred to as slurry wall in the us) is a structure formed and cast in a slurry trench (xanthakos, 1994).Slump cone slump fault slump fold slump mold

The slurry is a mixture of water and chemicals like bentonite designed to keep the cuttings in suspension so that the spoil can be easily pumped to the surface.The trench is simentensoly filled with slurry while clamshell digging the trench.The trench can be dug with a backhoe and often requires little or no maintenance.A system for constructing narrow underground walls utilizing the slurry trench method is disclosed wherein a first apparatus excavates from one end of a slurry filled trench and a second apparatus is utilized for filling the trench with a wall forming material and at least a part of the excavating and/or filling apparatus is floated on the slurry in the trench.Author links open overlay panel arturo ressi nicholas cavalli
