Intangiriro kuri basalt fibre geogrids

2025-02-13

1.Gusobanura fibre ya basalt geogrid
Basalt geogrid ni hatoranijwe ubudodo bwa basalt fibre, gukoresha imashini yintambara yo mumahanga yateye imbere ikozwe muri substrate, gukoresha imiterere yicyerekezo cyintambara, gukoresha neza imyenda mumbaraga zintambara, kugirango itezimbere imiterere yubukanishi, kugirango igire imbaraga zingirakamaro, imbaraga zamarira hamwe no guhangana nigitambambuga, hanyuma nyuma ya asfalt nziza ihinduwe neza hamwe numuyoboro wibikoresho. Irakurikiza ihame ryo guhuza ibisa, yibanda kumikorere yabyo hamwe nuruvange rwa asfalt, kandi ikarinda byimazeyo fibre substrate, igatezimbere cyane kurwanya abrasion hamwe nogukomera kwimyanya ya substrate, kugirango ikoreshwe mukuzamura pavement, kurwanya imvune zangiza nizindi mpanuka zo mumuhanda, kandi gushira iherezo rya kaburimbo ya asfalt biragoye gukemura ikibazo.

2.Ibiranga fibre yibanze ya geogrid

Igicuruzwa gifite ibyiza bya Imbaraga Zirenze, kuramba gake, kurwanya ubushyuhe bwinshi, modulus nyinshi, uburemere bworoheje, gukomera kwiza, kurwanya ruswa, igihe kirekire cyumurimo, byoroshye guhuza, nibindi, birashobora gukoreshwa cyane mumihanda ya sima ishaje, gufata neza ikibuga cyindege, inkombe, inkombe zinzuzi, kurinda imisozi, kuvura umuhanda no kongera ibiraro mukuzamura ubukana, gushimangira ubukana, kongera imbaraga, kumeneka hamwe nibi bikurikira byerekana, kandi Irashobora gukwirakwiza pavement irimo guhangayika kandi ikongerera igihe cyumurimo wa kaburimbo.
Imbaraga zingana cyane no kuramba: basalt fibre geogrid ishingiye kuri fibre ya basalt nkibikoresho fatizo, kandi imbaraga za basalt fibre tensile imbaraga ni nyinshi cyane, kuruta izindi fibre nicyuma gisanzwe. Mugihe kimwe, ifite modulus ndende, ifite imbaraga nyinshi zo kurwanya deformasiyo, kurambura kuvunika ntabwo biri munsi ya 3%.
Nta kunyerera kwigihe kirekire: nkibikoresho bishimangira, hamwe nubushobozi bwo kurwanya ihindagurika mugihe cyumutwaro wigihe kirekire ko kurwanya ibinyabuzima ari ingenzi cyane, fibre ya basalt ntizanyerera, kugirango ibicuruzwa bishobore gukomeza gukora igihe kirekire.
Ubwiza buhebuje bwumubiri nubumara: fibre ya basalt ubwayo ifite imbaraga zo kurwanya aside na alkali kwangirika, geogrid ya basalt irashobora kurwanya imyambarire itandukanye ndetse nisuri yimiti, ariko kandi ikarwanya isuri yibinyabuzima n’imihindagurikire y’ikirere, kugirango imikorere yayo idatakara.
Ubushyuhe bwiza bwumuriro: gushonga fibre ya basalt muri 1500 ° C cyangwa irenga, gukoresha igihe kirekire ubushyuhe buri hagati ya -260 ° ~ 650 °, kugirango urebe ko basalt geogrid mugikorwa cya pave kugirango uhangane nubushyuhe bwo hejuru.
Igiteranyo cyo gufunga no kubuza: kuko i basalt geogrid ni mesh imiterere, beto ya asfalt muri rusange irashobora kwinjizwa, kugirango habeho gufunga imashini yashizwemo. Uku kubuza kubangamira urujya n'uruza, kugirango ivangwa rya asfalt mugihe cyumutwaro rishobora kugera kumurongo mwiza wo guhuzagurika, ubushobozi bwo gutwara imitwaro myinshi, imikorere myiza yo kohereza imizigo no guhindura ibintu bike.
Kandi imvange ya asfalt ihuza: basalt geogrid mugikorwa cya nyuma yubuvuzi ibikoresho bisize byateguwe kubuvange bwa asfalt, buri fibre iba yuzuye neza hamwe na asfalt ifite urwego rwo hejuru rwo guhuza, bityo ukemeza ko fibre ya basalt fibre geogrid murwego rwa asfalt itazatandukanwa nuruvange rwa asfalt, ahubwo ihujwe hamwe.
Kurwanya umunaniro ukabije: basalt geogrid murwego rwa asfalt, irashobora kuba umuvuduko wibiziga hejuru yumuhanda hamwe no guterwa no guhagarika umutima no guhagarika umutima, gushiraho akarere ka buffer hagati y’ibice byombi by’imihindagurikire, guhinduka gahoro gahoro aho guhinduka bitunguranye, bikagabanya ihinduka ritunguranye ry’imihindagurikire y’ubutaka bwa asfalt. Muri icyo gihe, uburebure buke bwa basalt geogrid bugabanya kugorora kaburimbo, kwemeza ko kaburimbo itazabaho ihinduka rikabije.
Ubushyuhe bwo hejuru burwanya ubukana: ikoreshwa rya basalt geogrid murwego rwa asfalt, igira uruhare rwa skeleton murwego rwa asfalt. Guteranya muri beto ya asifalt unyuze kuri gride, ugakora sisitemu yo gufunga imashini ikomatanya, kugabanya urujya n'uruza rwinshi, kongera imbaraga zo guhuza imbaraga murwego rwo hejuru rwa asfalt, hejuru yubutaka bwa asfalt ya buri gice cyundi, bikumira asifalt yubuso bwa asifalt kugirango ikine uruhare rwo kurwanya kurigata.
Kurwanya ubushyuhe buke kugabanuka: mubihe byubushyuhe buke, kugabanuka kwa beto ya asfalt, bikaviramo guhangayika, iyo guhangayika birenze imbaraga zingana za beto ya asfalt, bikaviramo gucika. Basalt geogrid mugukoresha urwego rwa asfalt, kunoza urwego rwububasha bwimbaraga zinyuranye, kugirango imbaraga za tensile ya beto ya asfalt itezimbere cyane, irashobora kunanira imihangayiko nini itabangamiwe. Byongeye kandi, nubwo kubera agace kahantu hacitse, mubice bivamo guhangayikishwa cyane, na transfert ya basalt geogrid ikabura, ibice ntibizakura mubice.
Kugabanuka gutinda kumeneka: muri asfalt hamwe na basalt geogrid igorofa, kubuza impagarara cyangwa guhagarika umutima biterwa numutwaro wimodoka, kurekura umurego, nkibikoresho bya asifalt beto ibikoresho byongera imbaraga, kugirango ugere kubintego yo gutinda kugabanya ibice.

3.Gukoresha geogrid hamwe na fibre yibanze
Geogrid mugushira mubikorwa ibitekerezo byingenzi byimbaraga, kurwanya amarira, hamwe no guhuza ubutaka, kuramba nubukungu bwacyo. Kugeza ubu, geogrid yakoreshejwe mu rwego rw’imihanda nyabagendwa, umuhanda wa gari ya moshi, inkombe z’ubutaka, kuzamura imisozi ya banki, gushyigikira no kugumana imiterere, gusana ibice byavunitse, gusana ibyangiritse no gusana no gukumira no gukumira no gukumira. Cyane cyane ikoreshwa rya geogrid mukuzamura pavement no gukumira ibice byo gutekereza. Gutekerezaho ni umuhanda-nyakatsi urwego rwimihindagurikire yubushyuhe cyangwa umutwaro ufite nini cyane kandi ukabyara ibice, kandi unyuze hagati yikwirakwizwa ryimihindagurikire yumuhanda, bikabyara inzira ihagaritse cyangwa itambitse hagati yurwego kandi bigatuma umuhanda ucika. Gukoresha geogrid ikora cyane birashobora kunoza neza imbaraga zogosha hagati no kugabanya umunaniro wumuhanda, bikwirakwiza impungenge, bityo bikarinda neza ko habaho ibice bya kaburimbo, kandi bikagabanya cyane amafaranga yo gufata neza umuhanda. Gutekerezaho ni ibintu bikunze kuboneka muri pavement ya asfalt. Kubice byo kumurika hejuru yumuhanda, gushyira urwego rwa geotextile hagati yubuso bwa asfalt hamwe no munsi yacyo birashobora gukuraho cyangwa gutinda kubyara ibisekuru byerekanwa mubice byubuso, bityo bikongerera igihe cyo gukora umuhanda. Ariko pavement ya asfalt isuka ubushyuhe bugera kuri 160 ℃, bikavamo geotextile cyangwa polymer geogrid, guhindagurika, koroshya, kuburyo imikorere yayo igabanuka cyane. Gukoreshwa muri asfalt pavement geogrid nibyiza gukoresha basalt fibre geogrid, kubera ko basalt fibre geogrid ifite ubushyuhe bwiza, hamwe nimbaraga nyinshi, modulus nyinshi, kuramba gake, coefficient nkeya yo kwagura ubushyuhe nibindi biranga.
