Claims (21)
1. Polymerintegralgeonet dannet ved uniaksialt eller biaksialt at strække og udlægge et måtteagtigt materiale med et system af perforeringer eller indhak til flere indbyrdes forbundne, orienterede strenge med et arrangement af åbninger deri, kendetegnet ved, at det måtteagtige materiale og polymergeonettet er fremstillet af polyethylente-rephthalat.
2. Polymerintegralgeonet ifølge krav 1, hvor det måtteagtige polyethylenterephtha-latmateriale er biaksialt strukket og udlagt til dannelse af et geonet med molekylært langsgående orienterede strenge og molekylært tværgående orienterede strenge, som er indbyrdes forbundne med orienterede mødepunkter, der definerer generelt kvadratiske eller rektangulære netåbninger.
3. Polymerintegralgeonet ifølge krav 1, hvor polyethylenterephthalaten er en homopolymer eller en copolymer.
4. Polymerintegralgeonet ifølge krav 1, hvor polyethylenterephthalaten er udvalgt fra gruppen bestående af amorf polyethylenterephthalat, krystallinsk polyethylenterephthalat, og polyethylenterephthalatglykol.
5. Polymerintegralgeonet ifølge krav 1, hvor det måtteagtige polyethylenterephtha-latmateriale er uniaksialt strukket og udlagt til dannelse af et generelt kvadratisk eller rektangulært net af i det væsentlige parallelt orienterede strenge og et sæt af i det væsentlige parallelle tværstænger, der generelt står i lige vinkler på strengene, hvor en ende af hver streng er udlagt ind i tilstødende parallelle tværstængers strenge.
6. Polymerintegralgeonet ifølge krav 1, hvor nettet er konfigureret til struktur- eller konstruktionsforstærkningsformål.
7. Integralgeonet ifølge krav 1, hvor det måtteagtige materiale har en begyndelsestykkelse på mindst cirka 1,4 mm, og hvor det måtteagtige begyndelsesmateriale og inte-gralgeonettet er fremstillet af krystallinsk polyethylenterephthalat.
8. Integralgeonet ifølge krav 7, hvor polyethylenterephthalatstrengene indbefatter i det væsentlige tværgående orienterede strenge forbundet med i det væsentlige langsgående orienterede strenge.
9. Udgangsmateriale til fremstilling af et polymerintegralgeonet dannet af et måttelignende materiale med huller eller fordybninger deri, som giver åbninger, når det måtteagtige materiale strækkes uniaksialt eller biaksialt, kendetegnet ved, at det måtteagtige materiale er fremstillet af polyethylenterephthalat.
10. Udgangsmateriale ifølge krav 9, hvor polyethylenterephthalaten er krystallinsk polyethylenterephthalat.
11. Udgangsmateriale ifølge krav 9, hvor det måtteagtige materiale har en begyndelsestykkelse på mindst 1,4 mm.

14. Jord konstruktion omfattende en masse af partikelformigt materiale, der er forstærket ved deri at indlejre et polymerintegralnet i henhold til krav 1.
15. Fremgangsmåde til forstærkelse af en masse af partikelformigt materiale, hvilken fremgangsmåde omfatter at indlejre polymerintegralgeonettet i henhold til krav 1 i massen af partikelformigt materiale.
16. Fremgangsmåde til fremstilling af et polymerintegralgeonet dannet ved strækning og udlægning af et måtteagtigt udgangsmateriale med huller eller fordybninger deri til tilvejebringelse af flere indbyrdes forbundne, orienterede strenge og konfigurering af hullerne eller fordybningerne som geonetåbninger, kendetegnet ved, at det måtteagti-ge udgangsmateriale og polymerintegralgeonettet er fremstillet af polyethylenterephthalat.
17. Fremgangsmåde ifølge krav 16, hvor det måtteagtige polyethylenterephthalatud-gangsmateriale er orienteret ved uniaksial eller biaksial strækning.
18. Fremgangsmåde ifølge krav 16, hvor polyethylenterephthalaten er krystallinsk polyethylenterephthalat.
19. Fremgangsmåde ifølge krav 18, hvor det måtteagtige udgangsmateriale har en begyndelsestykkelse på mindst 3 mm.
20. Fremgangsmåde ifølge krav 16, hvilken fremgangsmåde yderligere omfatter trinnet at manipulere en variabel forbundet med polyethylenterephthalaten for at forbedre modstandsdygtigheden af integralnettet over for hydrolyse, idet variablen udvælges fra gruppen bestående af carboxylendegruppe, molekylvægt, krysta Min itet, orientering, overfladeareal, temperatur, pFI-værdi og kation-tilstedeværelse.
21. Fremgangsmåde til tilvejebringelse af en geonetkonstruktion ved uniaksialt eller biaksialt at strække et måtteagtigt udgangsmateriale med huller eller fordybninger deri til tilvejebringelse af et integralgeonet med flere orienterede strenge og flere netåbninger, og at indlejre integralgeonettet i en masse af partikelformigt materiale, kendetegnet ved, at det måtteagtige udgangsmateriale og integralgeonettet er fremstillet af krystallinsk polyethylenterephthalat.
