Abstract

Tema ovog rada su CIPP (eng. cured-in-place pipe) cijevi koje se koriste za sanaciju podzemnih netlačnih cjevovoda za odvodnju i kanalizaciju bez iskopa. Prikazano je laboratorijsko ispitivanje savojnih svojstava CIPP-a koje je provedeno u Laboratoriju za ispitivanje konstrukcija u Zavodu za tehničku mehaniku na Građevinskom fakultetu. Prikazani su rezultati i analiza podataka. Izrađeni su numerički modeli u računalnom programu Abaqus, koji prikazuju ispitivanje savijanjem u tri točke na ravnim i zakrivljenim uzorcima. Provedena je validacija numeričkog modela sa zakrivljenim uzorcima na temelju eksperimentalnih rezultata. Prema normi HRN EN ISO 11296-4 uspoređene su računske i numeričke vrijednosti savojnog modula. Provedena je analiza utjecaja geometrijskih karakteristika kod zakrivljenih i ravnih uzoraka.

Abstract (english)

The topic of this paper are cured-in-place pipes (CIPP) used for trenchless rehabilitation of underground non-pressure pipelines for drainage and sewage. The laboratory test of the flexural properties of CIPP, conducted in the Structural Testing Laboratory of the Department of Engineering Mechanics at the Faculty of Civil Engineering, is presented. The results and data analysis are presented. Numerical models, simulating the three-point bending test on flat and curved test pieces were created using the Abaqus software package. The numerical model with curved samples was validated based on the experimental results. According to the standard HRN EN ISO 11296-4, the calculated and numerical values of the flexural modulus were compared. An analysis of the influence of geometrical characteristics for flat and curved test pieces was performed.
