Project description

FERGES company is a supplier of steel pipes for earthworks and foundation works in 2018, works were carried out to strengthen the soil of the pit for the construction of the Capital Towers residential complex, our company happened to participate in this project as a supplier of steel pipes.

The use of the "wall in the ground" method for fixing the walls of the pit was due to the increased level of groundwater at the location of the construction site, as well as the need to build a deep pit in which four underground floors were located. Such a depth would require very large dimensions when excavating a pit with slopes, while the "wall in the ground" whose depth was 25-27 m, allowed to limit the dimensions of the excavation to the dimensions of the structure.

The mechanical characteristics of the site soils made it possible to use factory-made products, due to which the wall in the soil was made with a prefabricated monolithic version. However, such a modification did not eliminate the need for a spacer system, the horizontal elements of which were made of round steel pipes with a diameter of 1020 mm and a wall thickness of 12 mm, resting on a belt of steel of a smaller diameter of 530 mm with a wall of 9 mm running along the perimeter of the pit. Delivery was carried out in the stages planned by the contract, which made it possible to carry out the planned scope of work without suspending the construction process. Another difficulty was the delivery of large-diameter pipes since the object is located in the very center of the city. As a result of the correctly and carefully completed preparatory work, the transportation of large diameter pipes by FERGES company motor vehicles took place exactly on time and following all the requirements of the legislation of the Russian Federation. A reliable guarantee of this is the unconditional professionalism and absolute responsibility of our company's specialists.
