Creating a microclimate in underground structures

 

Introduction

Building of buildings and constructions under the ground has its own characteristics, the complexity increases when the object is built in the conditions of permafrost.

This is due to the special properties of permafrost, which should be considered when designing industrial and civil objects. The existing recommendations in this area focused mainly on the preservation of permafrost, the creation of special conditions that hinder the development of their thawing and degradacii their physico-mechanical properties .

Practical implementation of these recommendations has led to widespread use in these climate zones pile foundations, subfield ventilated, etc. significantly reduce the heat ducts from the buildings to the ground, which prevents them from thawing.

However, the need to ensure public safety in cases of technological disasters, the requirements of bodies for civil defense and emergencies give the task of construction of underground structures, including in the conditions of permafrost, a particular specificity.

The existing experience of building such facilities Continue reading

Megalithic constructions of the Urals

Megalithic constructions of the Urals.

Megalithic structures are one of the most impressive archaeological sites. Their various types are known in the Mediterranean, in parts of Northern Europe and on the Atlantic coast of Western Europe. Under this concept combined a variety of masonry structures: dolmens, avenues of menhirs, and rock gallery-tombs (Gimbutas 2006). In Eastern Europe up to the present time the only known megalithic structures were the dolmens of the Western Caucasus.

In recent years, appeared of megalithic monuments in the southern Urals, dated to the bronze age. Usually they are presented with avenues of menhirs, however, the sizes of these structures were not as impressive. Therefore, to call these megalithic structures with great care. However, studies over the last five years has led to the opening of a brand new Ural type of monuments that can be named megalithic with good reason.

The opening of the Ural dolmens was largely unexpected for experts, especially since it was made not by archaeologists. In the last 10 years the historians had published information about Ural dolmens, located to the North of the city Pyshma, Sverdlovsk region. The initiator of these searches were Cheerful A. A. and V. G. Nepomnyaschiy. They suggested that these are ancient monuments close to Caucasian and European structures of this Continue reading

DESIGN AND CONSTRUCTION OF THE METRO

a survey on the construction of the underground railroad in Moscow appeared at city Council repeatedly: in 1902, was considered the project of engineer P. I. Balinskiy, in 1912 — the project of engineer P. P. yureneva and others. In 1918-1920 architectural Studio, headed by A. V. Shchusev and I. V. Zholtovsky, in the reconstruction of the capital was proposed to construct the subway. This quick and convenient form of transport attracted the attention of specialists. But the need for it at the time is not yet ripe. If the existing sizes of passenger traffic could still do without the metro.

Before 1917, Moscow was served by two modes of public passenger transport — tram and horse riding. In the first years of Soviet power have increased the number of tram routes, and in 1924 opened bus traffic. By 1931 the population of the capital compared with the pre-revolutionary time has doubled. Moscow had a dense network of tram tracks and about 200 buses. 90% the volume of passenger transportation had the tram 9% — on the bus. The trams were overloaded beyond measure. On the bus was talking about how foreign the new. Then there was the need to build an underground road.

In 1931 on the basis of conducted surveys and engineering-geological Continue reading
