At the exit from Lviv in the direction of Vynnyky, additional major repair works are under way on Lychakivska Street on the section from Bukova Street to the city boundary. Here, the slope is being reinforced and the pavements strengthened; in particular, on a section approximately 150 m long, a multi-layer reinforcement system is being installed.
According to LKP «Lvivavtodor», the technology used involves constructing the structure in layers. First, the base is prepared and the metal frames of the permanent formwork are installed. After this, geogrids are laid, sand is backfilled and carefully compacted. These layers are formed sequentially, one after another.
According to the director of LKP «Lvivavtodor», Mykola Vlasiuk, part of the work, in particular the installation of the metal frames and geogrids, is carried out manually, while special machinery is used at other stages. This multi-layer structure is intended to ensure the stability of the slope and provide additional protection for pedestrian areas.
As a reminder, works to reinforce the retaining walls and slopes on both sides of the road on this section of Lychakivska Street began on 19 March. The contractor is TOV «Avtomagistral-Pivden». Due to the operation of large-sized machinery, certain sections of the road are temporarily closed, and traffic is organised in a contraflow system with traffic light control.
At the end of August, on this same section, the construction of more than 100 m of a gabion retaining wall was completed — metal mesh baskets densely filled with stone, which also serve to reinforce the slope.
