Special hydraulic works of the joint-stock company Gidrospetsstroi for the 850th anniversary of Moscow

Abstract

1. The joint-stock company Gidrospetsstroi has accumulated fundamental experience in the development and introduction of progressive technologies in the area of special underground works, including underpinning foundations, construction of pile foundations, and stabilization of weak soils by various methods. 2. The team at Gidrospetsstroi for more than 40 years has successfully carried out antiseepage and reinforcement measures on civil and industrial objects in Moscow and the Moscow Oblast, including a number on the instructions of the Russian Federation government and Moscow city government. By now works have been carried out on more than 1000 objects just in the capital. 3. To prevent developing deformations of buildings and structures, Gidrospetsstroi used the construction of bored-injection (rootlike) piles for the first time in domestic practice in Moscow (1976). This technology was subsequently introduced actively on objects in Moscow and abroad. 4. For the 850th anniversary of Moscow, Gidrospetsstroi carried out works on constructing bored cast-in-place and bored-injection piles as well as grouting of foundations and foundation-soil contact at many objects of the capital. 5. The long accumulated experience of performing special works, highly skilled engineers and workers, mobility and flexibility of the system, which includes the necessary links—all this gives ground to consider that the joint-stock company Gidrospetsstroi can successfully accomplish almost all new upcoming tasks. .
