Consolidation (reinforcing) of Pisatel area
"Reinforcement of landslide – bus stop Pisatel, road IV-90023 "Golden Sands - Varna", within which the following facilities will be carried out: PILOT CONSTRUCTION № 1; PIT № 1, 2 and 3; horizontal drainage probing to the pits and discharging of leakages from shafts; supporting wall; anchoring constructions № 1 and 2; technological ways; control and measuring system". The site covers part of the coastal slope of residential area Chaika, including the way of road IV-90023 Varna – Golden Sands with length of 280 m, in the area of bus stop Pisatel. The region is located on the territory of old, conditionally stabilized landslides. The general strengthening scheme of the site stipulates performance of facilities and activities, which will guarantee the flawless operation of road IV-90023 Varna – Golden Sands. The projects determines execution of technological roads and working platforms, draining activities and load-bearing units.
Technological roads
Roads are with length of 216,00 m and are extension of the existing road between the hotels built and the working platforms for anchoring construction – 1 and anchoring construction -2.
