Description
Oppfinnelsen angår en fremgangsmåte til å forbinde' en The invention relates to a method for connecting a
rørledning under vann med en tunnel på land, hvor det fra landsiden er sprengt en tunnel som ender blindt i umiddelbar nærhet av det sted hvor rørledningens forbindelse med tunnelen skal opprettes, og hvor det på dette sted i tunnelen støpes en betongblokkering med gjennomføringsåpning for et rør. pipeline under water with a tunnel on land, where a tunnel has been blasted from the land side that ends blindly in the immediate vicinity of the place where the pipeline's connection with the tunnel is to be established, and where a concrete block with a passage opening for a pipe is cast at this place in the tunnel .
I norske patentskrifter nr. 137461 og 139101 er foreslått In Norwegian patent documents no. 137461 and 139101 it is proposed
slike fremgangsmåter med en betongblokkering og henholdsvis bortsprengning av den gjenstående fjellpropp eller ved gjennom- such methods with a concrete block and respectively blasting away the remaining rock plug or by

Hensikten med oppfinnelsen er å tilpasse metoden for The purpose of the invention is to adapt the method for
gjennomboring ifølge norsk patent nr. 139101 til kjente rør-legningsmetoder, med inntrekning av rørledningen fra sjøsiden. drilling according to Norwegian patent no. 139101 to known pipe-laying methods, with the pipeline retracting from the sea side.
Dette oppnås ifølge oppfinnelsen ved det som er angitt This is achieved according to the invention by what is indicated
i kravet. in the claim.
Oppfinnelsen er en sammensetning av kjent teknologi for gjennomføring av en ny fremgangsmåte. Et utførelseseksempel på oppfinnelsen skal nedenfor forklares under henvisning til tegningen. The invention is a combination of known technology for carrying out a new method. An embodiment of the invention will be explained below with reference to the drawing.

Fig. 3 viser skjematisk tetnings- og faststøpningsorganene Fig. 3 schematically shows the sealing and casting members
for borstang og rørledning. for drill rod and pipeline.
Oppfinnelsens fremgangsmåte er karakterisert ved følgende The method of the invention is characterized by the following
trekk: traits:
En borstang 2 som forlenges med skjøteborstenger avhengig A drill rod 2 which is extended with extension drill rods depending
av fjellproppens lengde føres gjennom en pakningsboks bestående av et rørstykke 7 med tetningsorganer og gjennom et rørstykke 5 of the rock plug's length is passed through a stuffing box consisting of a pipe piece 7 with sealing means and through a pipe piece 5
innstøpt i en betongblokkering 6. embedded in a concrete block 6.
Under boringen mates borkakset vekk fra et borhode 1 med During drilling, the cuttings are fed away from a drill head 1 with
en skrue og med trykkvann fra trykkvannsdyser montert bak bor- a screw and with pressurized water from pressurized water nozzles mounted behind the drill
hodet 1 . Trykkvannet transporterer borkakset ut av det oppborede hull og ned i brønn 9 som på forhånd er utsprengt foran betongblokkeringen 6. Gjennom betongblokkeringen 6 er innstøpt et pumperør 8 som går ned i brønnen 9. Ved hjelp av en pumpe plassert på tunnelsiden pumpes borkaks ut til et lukket system. the head 1 . The pressurized water transports the cuttings out of the drilled hole and down into the well 9, which is previously blasted in front of the concrete block 6. Through the concrete block 6, a pump pipe 8 is embedded which goes down into the well 9. With the help of a pump located on the tunnel side, the cuttings are pumped out to a closed system.
Gjennom dette transportsystem for borkaks og bruk av skjøtestenger er det mulig å gjennombore en fjellpropp med et hori-sontalt hull, selv om overdekningen på vannsiden skulle bli liten, idet fjellproppens lengde ifølge oppfindelsen kun er avhengig av forholdene på stedet. Through this transport system for drilling cuttings and the use of extension rods, it is possible to drill through a rock plug with a horizontal hole, even if the coverage on the water side should be small, as the length of the rock plug according to the invention is only dependent on the conditions on the site.
Etter utført gjennomboring fjernes borhodet, skrue og trykkvannsdyser After drilling, the drill head, screw and pressurized water nozzles are removed
fra borstangen 2 på vannsiden ved dykker. Deretter monteres en krok på borstangen 2 og det opprettes en strekkforbindelse til rørledningen 10. Ved nå å reversere mateordningen på boremaskin 4, trekkes rørledningen 10 inn gjennom det oppborede hull, gjennom det innstøpte røret 5 og ved aktivisering av tetningsringene oppnås en tett forbindelse. Brønnen 9 igjenstøpes ved at betongmørtel pumpes inn gjennom røret 8. Dermed presses også mørtel inn i åpningen mellom rørledningen 10 og borhullet. For-bindelsen mellom rørledningen 10 og tunnelen er dermed etablert og rør-stykket 7 demonteres fra rørstykket 5. Den videre rørmontasje av rør-ledningen 10 skjer nå tørt inne i tunnelen. from drill rod 2 on the water side by divers. A hook is then mounted on the drill rod 2 and a tensile connection is created to the pipeline 10. By now reversing the feed arrangement on drilling machine 4, the pipeline 10 is pulled in through the drilled hole, through the embedded pipe 5 and by activating the sealing rings a tight connection is achieved. The well 9 is recast by pumping concrete mortar in through the pipe 8. This also forces mortar into the opening between the pipeline 10 and the borehole. The connection between the pipeline 10 and the tunnel is thus established and the pipe section 7 is dismantled from the pipe section 5. The further pipe assembly of the pipeline 10 now takes place dry inside the tunnel.
Andre karakteristiske trekk er at rørstykket 5 innvendig er forsynt med ledeskinner for sentrering av rørledningen 10 og tilknyttes rør for inji sering av mørtel. Foran betongblokkeringen 6 er det montert et støtte-lager 3 for borstangen 2. Dette lager har hydrauliske klemmer som holder lageret sammen under boringen, og som demonteres ved fjernstyring fra tunnelsiden etter utført boring. Other characteristic features are that the pipe section 5 is internally provided with guide rails for centering the pipeline 10 and is connected to pipes for injecting mortar. In front of the concrete block 6, a support bearing 3 for the drill rod 2 is mounted. This bearing has hydraulic clamps which hold the bearing together during drilling, and which are dismantled by remote control from the tunnel side after drilling has been completed.
For montasje bak betongblokkeringen 6 sprenges en omløpstunnel utenom denne. Denne omløpstunnel igjenstøpes med en vanntett adkomståpning. For installation behind the concrete block 6, a bypass tunnel is blasted outside of this. This bypass tunnel is recast with a watertight access opening.
En annen metode for montering er at det maskinelle utstyr anbringes Another method of assembly is for the mechanical equipment to be placed
før betongblokkeringen 6 igjenstøpes, og at det i denne er en vanntett, lukkbar åpning for eventuell inspeksjon før boring. before the concrete block 6 is cast again, and that there is a watertight, closable opening in this for possible inspection before drilling.
