PP Biaxial Geogrid polypropylene geogrid yo gushimangira umuhanda
Ibiranga ibicuruzwa
PP biaxial geogrid ikozwe muri polymer binyuze mu gusohora, gukora amasahani, gukubita inshyi hanyuma kurambura no kurambura.Ibikoresho bifite imbaraga zikomeye mubyerekezo birebire kandi bihindagurika, kandi iyi miterere irashobora kandi gutanga imbaraga zingirakamaro zo gukwirakwiza no gukwirakwiza uburyo bwiza bwurunigi rwiza mubutaka, bukwiranye no gushimangira ubuso bunini bwishingiro rihoraho.
Mu gukora PP biaxial geogrid, polymers izahindurwa kandi ihindurwe hamwe nubushyuhe no kwagura, bishimangira imbaraga zihuza iminyururu ya molekile kandi bigera ku ntego yo kuzamura imbaraga zabo.Kurambura kwayo ni 10% ~ 15% gusa yisahani yumwimerere.Niba karuboni yumukara nibindi bikoresho birwanya gusaza byongewe muri geogrid, birashobora gukorwa kugirango irwanye aside, alkali, ruswa no gusaza.
| 1, Biaxial Geogrid irashobora Kunoza ubushobozi bwo gufata umusingi |
| 2, Biaxial Geogrid irashobora Kurinda gucika no kugabanuka |
| 3, Biaxial Geogrid Nibyoroshye kubaka, kugabanya ibiciro no kubungabunga amafaranga |

Kwinjiza
(1) ubanza, umurongo uhanamye wa subgrade urekuwe neza.Kugirango tumenye ubugari bwa subgrade, buri ruhande rwaguwe na 0.5m.Nyuma yo kuringaniza ubutaka-fatizo, 25T vibratory roller ikoreshwa kumuvuduko uhagaze kabiri, naho umuvuduko wa 50T ukoreshwa inshuro enye.
(2) shyira 0.3m yubucucike buciriritse (bubi).Nyuma yo kuringaniza intoki nubukanishi, urujya n'uruza rwa 25T ruzahagarara kabiri.
