Round rocks and quarterly deposits.

Its natural humidity often lies in the range of 6-16%, the volumetric weight is determined by the value of 2.0-2.1 g/cm3 (sometimes more); It is developed only with pneumatic hammers and t. D.

As the foundations of structures, indigenous clay and other ages should be evaluated. But they, due to the differences in the genesis, have their own characteristics, which would be ignored by the mistake of the builders. For example, the black Jurassic clay of the Moscow Region and the Upper Volga contain a lot of pyrite, which has a harmful effect on reinforced concrete structures, and Permian clay is a large number of salts that are easily soluble in water, t. e. They are salted. This forces builders to be especially attentive to the moisturizing of the latter, which, as you know, is associated with an increase in porosity, can lead to uneven precipitation of structures, etc. D. This is important in such a type of work as a blind area of ​​the foundation.

In the case of construction on widespread younger quarterly deposits, the nature of their formation should be taken into account, the presence of relatively fresh and loose sediments, the non -restraint of individual layers by extension, the speed of shift in the vertical context, as well as small power, and in most cases, the inaccessibility of the layers of layers.

From the comparison of the given data, it is clear how the indigenous rocks and quarterly deposits differ abruptly. But the matter is not only in the difference in the age of breeds, which affects their features within the group, system, department, tier, horizon, layer, but also in their formation, t. e. genesis. In this regard, it is enough to compare the well-known glacial durable clays and weak lake-lactic clays to make sure to make sure the fairness of what was said.

All this taken together once again emphasizes that without knowledge of geology data in the broad sense of the word, it is impossible to successfully solve the tasks related to the study of the work of the pile-band system. This work shows that the processes occurring in clay soils when piles piles are mainly physico-chemical and the main one is thixotropics among them.
