Reconstruction Features of Drainage Works in Cohesive Soils

Abstract

Stated: features of drainage work in cohesive soils. Given: characteristics of processes and effects con-nected with physical and mechanical properties of clay soils. Shown: function of protective-filter materials in drainage work. Presented: analytic dependences for estimation of drainage parameters in cohesive soils with respect to imperfection of absorbing wells and contact strength structures. Assigned: water intake power of absorbing wells in cohesive soils can be increased with the use of depth filters. At drainage reconstruction it is recommended to use plastic pipes with the area of water intake holes being no less than 20 cm2/m.
