Abstract

Käesolevas töös annab autor ülevaate geodeetilistest töödest, mis tehti objektil „Balticconnector“. Töö objektil algas 2018. a. maikuus ja kestab tänaseni. 2019. a. mai seisuga on paigaldatud peaaegu 35 km torusid, kokku on paigaldada 53.4 km. Lõputöö esimeses osas antakse ülevaade objektist ja kasutatud instrumentidest. Seejärel tutvustab autor topograafilise plaani koostamist ja töö käigus esinenud probleeme. Tööd tehti elektrontahhümeetriga Topcon DS-103 ja GNSS vastuvõtjaga Topcon HiPer SR. Lõputöö teises osas on kirjeldatud mahamärkimistöid, mis koosnevad raadamisest; horisontaalpuuraukude, sealhulgas hülside märkimisest; ning piketaaži, telje ja põlve märkimisest. Selles peatükis loetleb autor püstitatud eesmärke ja tööde teostamiseks kasutatud meetodeid. Lõputöö viimases osas antakse ülevaade teostusmõõdistamisest. Peatükis on kirjeldatud kraavi, hülsi ja torustiku teostusmõõdistust. Kirjeldatakse ka torustiku teostusmõõdistamisele kehtivaid nõudeid. Nii topograafiline plaan kui teostusmõõdistused teostati vastavalt topo-geodeetilistele uuringutele ja teostusmõõdistamisele esitatavatele nõuetele.

Geodetic Servicing of Gas Pipeline. This present thesis provides an overview of geodetic work performed on Balticconnector. Work on the premises commenced in May of 2018 and is still ongoing to date. As of May 2019, nearly 30 km of pipeline have been laid down out of total of 54.4 km. Part One of the graduation thesis renders an outline of the premises and of the instruments used. Next, the paper describes the preparation of the topographical survey plan and lists problematic issues that emerged during the course of the work. Work was performed using a Topcon DS-103 total station and a Topcon HiPer SR GNSS receiver. Part Two of the graduation thesis describes staking out work that consists in deforestation; staking out of horizontal wells, including sleeves; and marking out of stationing, axle, and knee. This chapter specifies the objectives set and methods used to perform relevant work. The last part of the graduation thesis provides an overview of the as-built survey. This chapter describes the ditch, sleeve, and as-built survey of the pipeline. Requirements applied to pipeline asbuilt surveying are also listed. The topographical survey plan and as-built surveys were carried out in adherence to requirements applicable to topo-geodetic surveys and as-built surveys.
