Abstract

The paper is dedicated to the development of methods of waterproofing curtains arrangement for seepage protection of irrigation canals. The analysis of the informational sources in the field of seepage protection of irrigation canals has been conducted together with the use of horizontal directional drilling and the bentonite usage. The innovative technology of such works is proposed. The gist of the innovative technology is the combination of horizontal directional drilling and waterproofing bentonite-containing mortar injection. The laboratory experiments of the protective curtain arrangement are conducted. Bentonite powder concentration per unit of volume of hardening mortar, discharge pressure (supply) of injection mortar, and duration of mortar supply are chosen as the most influencing technological factors. Soil filtration coefficient is selected as the most important indicator. It is concluded that the combination of values of low bentonite powder concentration and relatively high discharge pressure allows obtaining lowest soil filtration coefficient values.
