Abstract

Na lokaciji postojeće Dječje bolnice Srebrnjak u Zagrebu,
predviđana je dogradnja bolnice građevinom na istočnoj strani
postojeće zgrade. Zbog brežuljkastog karaktera topografije terena i
prosječnog nagiba ~26°, podzemni dio novoplaniranog dogradnog
objekta će se nalaziti u zasjeku koji će biti dubok i preko 12 m, te je
postojeću zgradu i iskop, odnosno građevinsku jamu, potrebno
zaštiti i osigurati stabilnost kosina.
Građevinske jame su iskopi u zemlji kojima se olakšavaju
građevinske aktivnosti kao što su radovi temeljenja, radovi na
podzemnim instalacijama, gradnja podruma i sl. Mogu biti plitke ili
duboke te mogu predstavljati značajne rizike za radnike, okolne
zgrade i okoliš ako nisu pravilno poduprte i zaštićene. Jedna od
učinkovitih metoda zaštite građevinskih jama je korištenjem pilota.
Piloti se postavljaju po obodu građevinske jame da bi se osigurala
bočna potpora i spriječilo urušavanje tla ili kosine. Piloti su
konstrukcijski elementi koji se koriste za prijenos opterećenja s
konstrukcije na tlo. Obično se koriste u geotehničkom inženjerstvu
za duboko temeljnje tj. podupiranje zgrada, mostova i drugih
struktura koje su izgrađene na mekom, slabom ili kolapsibilnom tlu.
Postoji nekoliko vrsta pilota, a izbor vrste ovisi o čimbenicima kao
što su uvjeti tla (čvrstoća, krutost, stišljivost), potrebna nosivost i
ograničenja konstrukcije.

Abstract (english)

The existing Srebrnjak Children's Hospital in Zagreb is going
to be expanded a with a building on its eastern side. Due to the hilly
character of the topography of the terrain and the average slope of
~26°, the underground part of the newly planned building will be
located in a cut that will be more than 12 m deep. Therefore, it is
necessary to protect the existing building and the excavation, i.e.
the construction pit, as well as to ensure the stability of the slope.
Construction pits are excavations in the ground that facilitate
construction activities such as foundation work, work on
underground installations, construction of basements, etc. They can
be shallow or deep and they can pose significant risks to workers,
surrounding buildings and the environment if they are not properly
supported and protected. Using piles is one of effective methods of
protecting construction pits.. Piles are placed around the perimeter
of a construction pit to provide lateral support and to prevent soil or
slope collapse.. Piles are structural elements used to transfer loads
from a structure to the ground. They are usually used in geotechnical
engineering for deep foundations, i.e. supporting buildings, bridges
and other structures that are built on soft, weak or collapsible soil.
There are several types of piles, and the choice of type depends on
factors such as soil conditions (strength, stiffness, compressibility),
required load capacity, and structural limitations.
