Reconstruction Progress of Tupoleva Street in Zhukovsky
29 October 2021
The reconstruction of Tupoleva Street in Zhukovsky commenced in 2018. Stroytransgaz JSC operates at the section of over 2.7 km from the road junction at the intersection of Tupoleva Street and Tupolevskoye Highway to the bridge over the Khripan River. During the project, the road will be expanded from two to six lanes, three in both directions, and a four-lane tunnel will be built. The estimated traffic speed on the new motorway will be 70 km/h with a prospective traffic flow of about 50,000 vehicles a day.
To date, the pit foundation development for the WDF tunnel facility (water drainage facility) has commenced. Production and auxiliary premises will be located there upon completion of the works. The main purpose of WDF is to collect storm water from the tunnel drainage network and pump it into the existing drainage network.
The depth of the foundation pit for the WDF will be 16 meters (the depth of the tunnel is 12 meters). To avoid the collapse of the foundation pit walls, the enclosing structures of the SASF (Special Auxiliary Structures and Facilities) have been built by now. They are bored piles installed along the perimeter of the foundation pit with jet grouting piles installed behind it to avoid groundwater inflow.
In addition, to reinforce the enclosing structures of the tunnel facility, four belts of ground anchors are now built to install girders along the perimeter of the enclosing structures. This will eliminate the risk of the SASF collapse during construction.
A closed drainage system is provided at the facility to drain surface water. Water from the pavement of the reconstructed Tupoleva Street is drained to the projected storm sewer with subsequent treatment in a local waste water treatment plant (LWP). To date, 2.2 km of storm sewers or 45% of the total amount have been completed.
The construction of beds* for sections 2-11 of the main course of the tunnel has been completed, and the workers commenced reinforcing and concrete embedding of the walls. There will be 35 sections in total. The minimum bed thickness is 1.4 m. The walls have a uniform thickness of 0.6 m. The maximum thickness of floor structures is 1.25 m. 20% of the scheduled concrete embedding works have been completed to date.
* The lower tunnel element where the road pavement is built.
The length of the new tunnel will be 712 m. It will have four traffic lanes. The tunnel will become part of a two-level road junction and provide smooth transit traffic.
In addition, the road pavement of the motorway (17,000 m2 or 25%) has been completed. Sidewalk and bus stop road pavement (2,600 m2) has been completed.
Construction and installation works on new overpasses are in progress. At one pedestrian crossing, the handrails are installed, and the superstructure is prepared for glazing. At the second crossing, the metal tower support structures are being built and painted. At the third crossing, load-bearing metal structures, staircases and turning platforms are installed. There will be five crossings in total, and two of them have been completed by now.
50 machine units and 300 workers such as builders, machine operators, engineers and technicians and others are involved at the construction site.
The Tupoleva Street section to be reconstructed is a continuation of the approach (built in 2016) to Zhukovsky from the M-5 Ural Highway. The completion of works will allow to increase the road capacity by redistributing the transit traffic and improving the vehicle accessibility of Zhukovsky and Ramenskoye municipal districts. The construction is scheduled to be completed in 2022.
