Underground construction
One of the structural units of Construction Association interbudmontazh, the company “Interbudtunnel” performs works on construction and installation of various underground structures, tunnels, engineering and transportation networks, as well as load-bearing walling of buildings and structures.
The company performs tunneling for various purposes in areas of high seismicity and complex geological conditions, as well as continuous improvement of the tunnels.
Interbudtunnel is a member of International tunneling Association (ITA) and a member of the International Association of horizontal directional drilling.
The company is equipped with modern and progressive. machines and mechanisms, necessary for the performance of all complex of works on construction of tunnels. Material and technical base “Interbudtunnel” includes three of the tunnel system ( two with a diameter of 6 m and one d 3.75 m), rolling stock, materials handling machinery, excavation equipment, Autonomous diesel power and ventilation systems, power equipment, surveying instruments and equipment, life support equipment, machinery for construction “wall in the ground”, equipment for drilling and blasting: drilling rigs, hammers, tunnel excavators, loaders, lifts, the shotcrete installation.

Mysterious Stonehenge
The harsh and inhospitable terrain seems plain of Salisbury in southern England. Icy chilly winds blow here all year round. Viewing a blog about travel. found an interesting photo of stone mounds in England. In the Neolithic period, about five thousand years ago, there survived in the harsh conditions the people about whom we know very little. Bronze age people and their descendants left behind something special. It strikes the imagination of mankind even today. Mounds stone rings and megalithic culture produce an indescribable impression.
Stonehenge is one of famous monuments of this culture. This is a special temple of eternity. If you look at the temple from the height of bird’s flight, he will reveal the secret of their structure.

Archaeologists were able to solve the who, when and how built the Stonehenge. Why was this temple built? To this question the answer is still not found. Continue reading
The most ancient structures in the world
Geological structure. Like North America, Eurasia millions of years ago was part of the ancient continent of Laurasia. From other continents of the globe it features an extremely complex crustal structure. This is the result of a long and complex geological history of its development.
Gigantic in size Eurasia is not only all Eurasian lithospheric plate . But some of the other Indo-Australian . Along the line of collision, the crust is crumpled in folds – they formed the Alpine-Himalayan fold belt . Therefore, the mountain that appeared in this zone, located on the fringes along the coast, as on other continents, and inland and southern parts of Eurasia. Along the East coast of the mainland stretches another fold belt Pacific . arising at the junction with the Pacific lithospheric plate.
Fold belt are seismic zones, where the intense movements of the earth’s crust, earthquakes and volcanoes. The largest active volcano in Europe within Mediterranean seismic belt is Hekla, Etna and Vesuvius . Active volcanoes of Asia – Klyuchevskaya Sopka, Fuji, Krakatoa, and others – are Pacific seismicheskogo. Continue reading
