Короткий опис(реферат):

Рассмотрены способы контрольных испытаний натурных свай статическими вдавливающими нагрузками обычным и ускоренным методами с учетом опыта их выполнения на стройках в Сумской области. У статті розглянуто способи контрольних випробувань натурних паль статичними вдавлюючими навантаженнями звичайним і прискореним методами з урахуванням досвіду їх виконання на будівництвах в Сумській області.

Usually Sumy region have very difficult geological condition for construction process. In most cases designers have necessary to use different types of pipes for creation appropriate foundation for the civil and industrial buildings. For creation of such foundation builders have possibility to use enough wide circle of different types of appropriate construction equipment. And in all cases after creation of the pipe’s foundation we need to organize of the pipe testing. There are many different types of such testing processes was suggested and described in appropriate Construction norms and rules. Usually, all of them require enough specific types of the testing equipment. Today we can say, that all of this methods depend from the level of development of the construction sciences. Modern Ukrainian Construction Codes suggest several methods of the pipe testing. Big part of them require essential amount of the time and money expenses. Generally, all existing testing methods require enough big volume of the labour. And usually they is not clear for full understanding in many cases. In such situations the appropriate experience of the engineers is very important for receiving of the correct results. All time the desire of the construction workers to receive more simple and cheap method of the pipe testing was very powerful. For big part of the cases of using of different type of the pipe testing methods we can underline, that all of them is really enough difficult scientific process. Every step of this process is very important for receiving of the real results. And appropriate condition of using equipment is very important also. And appropriate experience of all participators very important also. Next important step is preparation of the working program of the testing. We need to underline, that this moment require very high qualified engineers. Last edition of the Ukrainian Construction Code include one economic method of the pipe testing, but without description of the details of its using (particularly for difficult geological condition). The authors added their experience of carrying out of the tests of the industrial and bored piles by static pressing load (for the Sumy region). Recommendations about the accelerated test methods and also about the further perfection of the test methods of the piles are given. This is the next step for development of the test methods of the pipe in Ukraine.
