METHOD FOR RECONSTRUCTION AND RENOVATION OF VERTICAL JOINTS BETWEEN PREFABRICATED ELEMENTS OF HYDRAULIC STRUCTURES

摘要

The invention relates to the reconstruction and renovation of hydraulic structures (HS), for example to the reconstruction and renovation of waterfront (berth) and coast-protecting structures, shell-type concrete piles, concrete slabs and massif where is necessity for ground-impenetrable sealing of vertical joints between prefabricated elements. The method is characterized by ground-impenetrable sealing of vertical joints between prefabricated elements of wall of berth, for example between of shell-type piles, where close to their surfaces is sunk down the box from inside of berth on depth of designed mark. The cut off ground between box and surfaces of shell-type piles is taken away. In the formed cavity is inserted the bag, for example from nonwoven synthetic material, which is filled by inert material (sand, gravel). Thereby the offered method allows to decrease significantly the cost of works and making repair without stoppage of services of vessels.
