METHOD OF HYDRAULIC STRUCTURE CONCRETING Russian patent published in 2002 - IPC

FIELD: construction engineering; applicable in concreting of hydraulic structures, including those with small joint openings. SUBSTANCE: method includes injection of cement mortar into section-to-section joints. Cement mortar is dispersed and contains surfactant and introduced coagulant. Cement mortar is injected to section-to-section joints by tiers, from bottom upward, and from sides to center of structure. Prior to injection of mortar into joint, structure base is subjected to strengthening cementation. In so doing, motion of section to headwater is measured and stressed-strained state of structure is determined. EFFECT: higher efficiency of work due to improvement of stressed- strained state of structure. 4 dwg, 3 tbl
