“…Test integriteta šipa sa senzorom (SIT) u praksi se zove i test eha zvuka (SET) ili test eha šipa (PET), a pripada grupi niskodilatacionih testova (LST). Test integriteta šipa sa senzorom (SIT) zasniva se na teoriji jednodimenzionalne propagacije talasa kroz šip, s ciljem utvrđivanja: stvarne dužine šipa, postojanje defekata i diskontinuiteta i redukcije poprečnog preseka šipa [6]. Takođe, analiziraju se: promena signala u domenu glave šipa, kvalitet odziva signala u bazi šipa, promena…”

“…Sonic Integrity Test (SIT) is in practice also called the Sonic Echo Test (SET) or Pile Echo Test (PET), and it belongs to the group of Low Strain Tests (LST). SIT is based on the theory of one-dimensional wave propagation through the pile, with the aim of determining: the actual length of the pile, existence of defects and discontinuities and reduction of the pile cross-section [6]. In addition, it analyzes variation of signal in the pile head domain, signal response quality at impedance duž stabla šipa, promena slojeva tla u kojima je šip izgrađen i postojanje proširenja poprečnog preseka duž stabla šipa.…”

“…amplitudes as a function of the corresponding signal Test integriteta šipa sa sondama (CSL) zasniva se na propagaciji talasa, primenom sondi s razdvojenim transmiterom i risiverom. Ovim testom se interaktivno i simultano, između instaliranih cevi u šipu, detaljno može ispitati integritet šipa celom dužinom po svim poprečnim presecima [6]. Ispitivanje integriteta sprovodi se kod svih tipova armiranobetonskih bušenih šipova.…”

“…Crosshole Sonic Logging (CSL) is based on wave propagation using separate transmitter and receiver sensor. With this test, the integrity of the pile can be thoroughly examined interactively and simultaneously, between the installed pipes in the pile, along entire length and across all cross sections [6]. Integrity testing is performed on all types of bored reinforced concrete piles.…”

“…The experience of the authors of this paper indicates that there is often an inadequate interpretation of the pile testing standards, even of the complete testing methodology. In this sense, the focus of this paper is to present some of the authors' experiences and to indicate the need for consistency in the implementation of the pile testing methodology presented in [6]. On the other hand, the application of several methods in pile integrity testing allows a better understanding of the final test solution.…”

Problematika ispitivanja integriteta šipova u poslednjih dvadesetak godina doživela je ekspanziju u pogledu: metodologije ispitivanja, tehnike i instrumentalizacije ispitivanja, raznovrsnosti tipova testova ispitivanja, softversko-hardverske podrške ispitivanju i teorije i obrade signala. U tom smislu, biti građevinski inženjer ili inženjer geotehnike sa iskustvom u oblasti projektovanja i izgradnje fundamenata nije dovoljan uslov, već se zahteva multidisciplinarnost u razmatranju problematike ispitivanja šipova. Pored standardnih naučnih disciplina, kao što su teorija elastičnosti, mehanika tla, dinamika tla, mehanika stena, fundiranje, ispitivanje konstrukcija, zahteva se i dobro poznavanje relativno novije naučne tematike interakcija konstrukcija-tlo, ali i drugih naučnih tematika (koje se primarno ne izučavaju u građevinarstvu ili u geotehnici), kao što su: talasna teorija, metoda karakteristika, teorija i obrada signala, termodinamička teorija i slično. U zavisnosti od stepena poznavanja određenih naučnih disciplina, zavisi i stepen pouzdanosti primenjene metodologije i interpretacije rezultata ispitivanja. Iskustva autora ovog rada pokazuju da se neretko nailazi na neadekvatnu interpretaciju standarda ispitivanja šipova, pa i kompletne metodologije ispitivanja. U tom smislu, težišta ovog rada jesu da se predstave određena iskustva autora rada i da se ukaže na potrebu za doslednošću u primeni metodologije ispitivanja šipova, koja je prikazana u radu [6]. S druge strane, primena nekoliko metoda u ispitivanju integriteta šipova omogućava bolje sagledavanje finalnog rešenja ispitivanja. Sve ove metode, primarno, zasnivaju se na talasnoj teoriji, ali i na procesiranju signala i na numeričkim analizama.

Nowadays, the decrease in number of urban areas for buildings is observed. Therefore, a novel construction of buildings has to be carried out in dense buildings areas. Construction buildings in historical districts become the most complicated goal. In order to preserve the cultural heritage, to ensure the safety of existing buildings and structures, and also safe building under, it is necessary to competently select the technology of digging pile foundations. Technological precipitation usually occurs at dynamic and vibration effects during the operation of equipment on the site and at pile construction. These effects cannot be analysed and depend on the quality of the work performed, the equipment chosen correctly and the technology applied. It is intended to eliminate the possible technological precipitation of buildings in the surrounding area by applying gentle technology-intensive operations. The article provides and systematizes defects that occur during CFA (Continuous Flight Auger), DDS (Drilling Displacement System), etc. The analysis of factors that influence on the appearance of defects has been made, and also the estimation of technologies from the preparation of wells when installing drilling and embroidery piles on the surrounding development in weak soils has been made.
