METHOD OF DREDGING IN ROCKS

摘要

FIELD: hydraulic engineering; may be in performance of drilling and blasting operations in dredging and formation of slopes. SUBSTANCE: method includes loosening of ground layer by drilling and blasting beyond the limits of design profile in strip covering slopes and adjacent territory and water area bottom. Loosened ground layer thickness is constant on bottom and variable thickness in slope height. Then ground is removed within the design profile, layer is filled over bottom area on larger depth and/or structure is erected for damping wave energy. Thickness of loosened layer in slope foot and on bottom shall be not less than the height of rated wave at approach to slope. EFFECT: reduced height of waves and wave pressure on slopes and reduced velocities of flows. 3 cl, 6 dwg
