BATTER DRAINAGE OF EARTHWORKS Russian patent published in 2017 - IPC E02B11/00 E02B3/12 

FIELD: construction.

SUBSTANCE: batter drainage on the lower slope is made of prefabricated gabion mattresses 1 of modular design with the width 1-1.5 m, the thickness 0.4-0.6 m and the length up to 2.5 m, and from the underlying layer 5 of the light fascines 2. The underlying layer 5 of light fascines 2 in the base and gabion mattresses 1 from above are bundled with galvanized metal wire. Along the top row of mattresses 1 with deepening into the slope the heavy mattresses of bags 6 with local soil and vegetation are stacked, which are reliably bundled with each other and with gabion mattresses 1 on the slope. At the foot of the drainage in the downstream above the gabion mattresses 1 the stone backfill 7 of gravel and pebble soil is made. The efficiency of the drain device design is improved.

EFFECT: batter drainage in the offered design can be most effectively used in critical conditions of rivers of plains and foothill areas, where low pressure earthen dams and dikes of fine sand and clay soils are erected.
