Tus nqi zoo tshaj
Kev lag luam tus nqi ntawm cov khoom siv hlau grooved feem ntau qis dua li ntawm cov hlau tsis muaj steel; txheem couplings thiab luj tshib tsuas yog ob peb mus rau ob peb lub kaum os yuan ib chav tsev. Nrog rau kev tswj hwm tus nqi yuav khoom, lawv tsim nyog rau feem coob ntawm cov qauv pej xeem, hauv nroog, thiab hluav taws kub - kev tiv thaiv dej thiab dej ua haujlwm.
Kev ua tau zoo ua tau raws li tus qauv yuav tsum tau ua
Lawv muab cov corrosion kuj ntawm cam khwb cia hlau nrog toughness mus txog ntawm cov hlau. Nrog lub zog compressive tshaj 100 MPa thiab zoo heev tiv thaiv seismic kev ua ub no, kev sib hais hauv av, thiab to, lawv ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv tseem ceeb xws li kev tiv thaiv hluav taws thiab dej dav dav thiab dej ntws, muab kev pabcuam lub neej ntawm ntau xyoo lawm.
Tus nqi qis rau cov khoom siv thiab kev tu
Cov khoom no ua raws li cov qauv kev sib koom ua ke hauv lub tebchaws, ua kom muaj kev lag luam siab, thiab siv cov khoom siv sib hloov tau. Kev teeb tsa yuav tsum tsis muaj cov txheej txheem tshwj xeeb, thiab cov nqi kho lossis hloov pauv tau qis dua li cov khoom siv niche, uas ua rau txo qis tag nrho cov tswv cuab hauv lub sijhawm ntev.
