FIELD: construction. ^ SUBSTANCE: invention relates to methods for erection of hydrotechnical structures in mining and construction industry, where return water is applied. Method for erection of hydrotechnical structure includes preparation of soil by means of its mixing with return water and further supply of produced pulp for its sorting into fine and large fractions, discharge of fine fractions into sections of settling tank, relief of water from one section of settling tank into another one. Large fraction after sorting is sent to hopper, afterwards water is supplied in it to transport large fraction into sections of settling tank, at the same time large fraction is sent to sections of settling tank from the side that is opposite to the point of fine fraction discharge. ^ EFFECT: improved efficiency of hydrotechnical structure action due to increased extent of return water treatment. ^ 4 dwg |
