INSPECTION OF THE TECHNICAL CONDITION OF HYDRAULIC STRUCTURE "HRANITNA NABEREZHNA" ON THE DNIPRO RIVER

English abstract

Inspection of engineering structures, including hydraulic structures, is one of the main components of maintaining their safety. The purpose of such measures is to assess the safety of operation to prevent various hydraulic accidents, preparation for scheduled or emergency repairs or reconstruction. Diving inspection of hydraulic structures includes a thorough inspection of the underwater part of the structure together with the survey of the changing horizon of the aquatic environment, the surrounding waters and the bottom near the berths, inspected the bottom in the areas of movement of vessels. This is how they detect clutter, sunken objects, washes and ravines. Hranitna Naberezhna is located in Kyiv on the right bank of the Dnieper River parallel to the embankment highway between the berth of the river station and the pedestrian bridge, with a total length of 350 m. In terms of design, the embankment is a retaining wall, which has built-in staircases with platforms that allow people to descend into the water. At the same time, the retaining wall has two structural types. The wall of the first structural type is located in those places where the size of the construction pit during building was limited due to the close location of the roadway. In these places the pit was fenced with a vertical metal tongue 6.5 m long. The sheet pile was driven from the pioneer pit from the mark of 95.75 m to the mark of 93.5 m, in which a pile field, a monolithic grid and a prefabricated reinforced concrete wall with an apron were arranged. The wall of the second constructive type differs from the first constructive type in that it is built in a pit without tongue and the rear pile row has not vertical, but 14 m long gantry piles. The outer faces of the embankment are decorated with granite: the top of the wall has granite stone, the front face is lined with granite slabs. During the inspection of the hydraulic structure of the granite embankment, which is on the section from the river station berth and the pedestrian bridge of the highway embankment, the detected defects do not pose a threat to the safe operation of the hydraulic structure. The technical condition of the main structural elements of the structure, namely: sheet pile row, pile field, retaining wall, bottom fastening, decoration, water area, superstructure, railing, stairs, cover of intermediate berth sites was satisfactory.
