Abstract

Antud lõputöö annab ülevaate Saue linna seni uusima kergliiklustee ehitamisest geodeedi pilgu läbi. Objekti valmimisaeg oli 2015. aasta detsembri algus ja pidulik avamine 31. detsembril. Suurem osa antud tööst keskendub pigem nendele ehitusetappidele, milles töö autor ise osales. Vähem kajastatakse teemasid, kus autorit ennast kohal ei olnud. Ehitusgeodeetilisi töid oli mitmeid: alusvõrgu rajamine, erinevad märkimised ja teostusmõõdistused. Lõputöös kirjeldatakse kõiki neid töid etappide kaupa, et lugejal tekiks arusaam ja ettekujutus ehitusobjektil toimunust. Räägitakse 3D- kleepsude otstarbest ja paigaldamisest ning lühidalt ka nende efektiivsusest tänapäeva tee-ehituses. Põhjalikumalt analüüsitakse objektil valitsenud ohtusid ja probleeme. Arutletakse, kuidas oleks saanud geodeetilisi töid, just piketaaži ja raadamispiiri märkimist võsaga kaetud ning raudteega rööbiti kulgevas alas kiiremini teostada. Analüüsitakse ka, miks topograafilise alusplaani jaoks mõõdistusi teinud geodeet võis määrata maapinna kõrgused valesti ning kas see oli tingitud ajalisest faktorist või tähelepanematusest. Selle juures tuuakse välja geoloogiliste uuringute tulemused antud probleemses lõigus. Teostusmõõdistusi analüüsides oli enamus ehitatust nõuetekohased ning hälbed jäid lubatud piiridesse. Küll aga esines lubatust suuremaid hälbeid truupide paigaldamisel. Truubi põhjakõrgus võis erineda kuni 5 cm, kuid ühel truubil oli erinevus 9 cm. Sellegipoolest võeti objekt vastu.

Abstract [en]

The tile of this thesis is „Engineering survey of pathway construction at Saue railway station“. This thesis gives an overview of the building of the latest light traffic road in Saue through the eyes of a geodesist. Completion time for this object was in the beginning of December 2015 and was officially opened on December 31st. Most of the work in the thesis will focus on those stages of the building in which the author took part in himself. Subjects where the author didn’t participate, will be less reflected. There were numerous construction surveys: establishing the grid, different stakings and as-built surveys. All these works will be described in stages, in order to give the reader an understanding and perception of what happened at the construction site. The thesis will explain function and installation of 3D-stickers and their effectiveness in modern road construction. The threats and challenges that occured on the object will be thoroughly analyzed. Questions like how the geodedic tasks, especcially marking the pickets and deforestation border on areas covered with underwood and that are parallel to the railway, could be done faster, will be discussed. Thesis will also analyze, why the geodesist, who made the measurements for the topographic base plan, might have marked the ground levels incorrectly, and whether it was due to the time factor or oversight. With this, the geodetic survey results in the problematic area, will be pointed out. The built survey analysis shows that the majority of what was built met the requirements and the deviations were within acceptabale limits. However, higher deviations occured while installing the culverts. The culverts height of the bottom could vary up to 5 cm, but on one of the culvert, the difference was 9 cm. Despite of that, the object was accepted.
