ROCK-FILL HYDRAULIC STRUCTURE WITH OPERATION PLATFORM, ALSO WITH MOORAGE FOR SMALL VESSELS

摘要

FIELD: construction. ^ SUBSTANCE: rock-fill hydraulic structure with an operation platform comprises a mooring and a wave-absorbing facilities with a metal frame. The mooring and wave-absorbing facilities adjoin each other in longitudinal direction. On top, inside and at both sides of the frame there is filling arranged. The filling forms a shaded slope at the structure's side, and a sea slope - at the opposite side. Metal frames are installed along the shaded slope with displacement towards it. The mooring facility is made of a row of prefabricated L-shaped elements. Each L-shaped element is made as a front supporting vertical metal element and a horizontal transverse reinforced concrete U-shaped bar. The supporting element is installed onto a foundation reinforced concrete slab. Ends of the U-shaped bar are arranged below water level. Prefabricated L-shaped elements are installed relative to each other with a certain pitch. Prefabricated L-shaped elements are rigidly connected to each other with the help of longitudinal reinforced concrete connecting elements, and also with the help of prefabricated reinforced concrete ribbed elements. Prefabricated reinforced concrete ribbed elements are installed on top along the whole upper surface of a horizontal transverse reinforced concrete U-shaped bar. The longitudinal reinforced concrete connecting element is made as a frame bar or a beam. The height of the longitudinal reinforced concrete connecting element does not exceed the height of the horizontal transverse reinforced concrete U-shaped bar. Pitch of prefabricated L-shaped elements is determined by calculation. Distance between metal frames does not exceed pitch of prefabricated L-shaped elements of the mooring facility. ^ EFFECT: increased extent of operation platform protection against waves effect and coastal flows. ^ 6 cl, 4 dwg
