WebbThe density of the slurry mix must be carefully monitored and adjusted to produce the correct outward pressure to prevent the trench walls from collapsing. Slurry walls are typically constructed by starting with a set of concrete guide walls, typically 1 metre (3 ft 3 in) deep and 0.5 metres (1 ft 8 in) thick. Webb68 A typical slurry trench in layered soils is illustrated in Fig. 2a. During trench excavation, 69 the trench is filled with slurry to avoid trench collapse. The pressure on the trench side 70 walls exerted by the slurry is typically less than the sum of the earth pressure at-rest and 71 hydrostatic pressure before excavation. http://ce561.ce.metu.edu.tr/files/2013/11/slurry-trench-wall-2.pdf chisholm slovenian home
