Intangiriro ku miterere y'ubutaka bwa basalt fibre

2025-02-13

1. Ibisobanuro bya fibre ya basalt akarere k'isi
Jewogridi ya Basalt ni ubudodo bwa basalt, gukoresha imashini yo kuboha igezweho iboshye mu buryo bw’umwimerere, gukoresha imiterere y’ubudodo bwo kuboha mu buryo bw’icyerekezo, gukoresha neza umwenda uri mu mbaraga z’ubudodo, kunoza imiterere yabwo, kugira ngo bugire imbaraga zo gukurura, bugire imbaraga zo gucika no kudacika, kandi nyuma yo gukoresha asphalt nziza yahinduwe itwikiriwe n’urusobe rw’ibikoresho. Ikurikiza ihame ryo guhuza ibintu kimwe, yibanda ku mikorere yayo ivanze n’uruvange rwa asphalt, kandi ikarinda byuzuye fibre substrate, irushaho kunoza cyane uburyo bwo kurwanya kwangirika no kudacika kw’ubudodo, kugira ngo ishobore gukoreshwa mu kunoza inzira, kurwanya imiyoboro y’amazi n’ibindi byago byo mu muhanda, kandi guhagarika inzira ya asphalt biragoye kongera ikibazo.

2. Ibiranga fibre geogrid y'ibanze

Ibicuruzwa bifite ibyiza byo Imbaraga nyinshi, uburebure buke, ubushyuhe bwinshi, modulus nyinshi, uburemere bworoheje, gukomera neza, kurwanya ingese, kumara igihe kirekire, byoroshye gushyiramo, nibindi, bishobora gukoreshwa cyane mu muhanda wa sima ushaje, kubungabunga inzira y'ikibuga cy'indege, inkombe z'uruzi, kurinda imisozi, gutunganya inzira z'umuhanda n'ibiraro n'ibindi bikorwa by'ubuhanga, bishobora guha umuhanda uburyo bwo kongera imbaraga, gukomeza, gukumira umunaniro ukabije mu muhanda, kwaguka kw'ubushyuhe n'ubukonje no guhindagurika kw'imivuduko n'inyuma y'imivuduko ikurikira, kandi bishobora gukwirakwiza umuhanda ufite imbaraga no kongera igihe cyo gukora umuhanda.
Ingufu nyinshi zo gukurura no kurekura gato: fibre ya basalt geogrid ishingiye kuri fibre ya basalt nk'ibikoresho fatizo, naho imbaraga zo gukurura fibre ya basalt ni nyinshi cyane, kurusha izindi fibre n'icyuma gisanzwe. Muri icyo gihe kandi ifite modulus nyinshi, ifite ubudahangarwa bukomeye bwo kwangirika, kurekura kwa fracture ni munsi ya 3%.
Nta gukurura igihe kirekire: nk'igikoresho gikomeza imbaraga, gifite ubushobozi bwo kurwanya guhindagurika mu gihe cy'umutwaro w'igihe kirekire, ubudahangarwa bw'igitutu ni ingenzi cyane, fibre ya basalt ntizakurura, kugira ngo ibicuruzwa bikomeze gukora neza igihe kirekire.
Ubudahangarwa bwiza cyane ku mubiri no mu mikorere: fibre ya basalt ubwayo ifite ubudahangarwa bukomeye ku ibara rya aside na alkali, imiterere y’ubutaka ya basalt ishobora kurwanya kwangirika gutandukanye ku mubiri no kwangirika kw’imiti, ariko kandi ikarwanya isuri y’ibinyabuzima n’imihindagurikire y’ikirere, kugira ngo imikorere yayo idacika.
Ubushyuhe buhamye: aho fibre ya basalt ishonga muri 1500 ° C cyangwa irenga, ikoreshwa mu gihe kirekire ry'ubushyuhe buri hagati ya -260 ° ~ 650 °, kugira ngo hamenyekane ko geogrid ya basalt mu mikorere yo kubaka pavement kugira ngo ihangane n'ubushyuhe bwinshi.
Igiteranyo cy'ingufuri n'imipaka byashyizwemo: kubera ko geogrid ya basalt ni imiterere y’urushundura, beto ya asphalt iri mu gice cy’urushundura ishobora kwinjiramo, kugira ngo habeho uburyo bwo gufunga bukozwe mu buryo bwa mekanike. Iyi mbogamizi ibangamira urujya n’uruza rw’ibice by’urushundura, kugira ngo uruvange rwa asphalt mu gihe cy’umutwaro rushobore kugera ku rwego rwo hejuru rwo gufunga, ubushobozi bwo gutwara imizigo bwinshi, imikorere myiza yo kohereza imizigo no kudahinduka cyane.
Kandi guhuza imvange ya asphalt: imiterere ya basalt mu buryo bwo kuvurwa nyuma yo kuvurwa ibikoresho bitwikiriwe byagenewe imvange ya asphalt, buri fibre yuzuye asphalt ifite urwego rwo hejuru rwo guhuza, bityo bigatuma imiterere ya basalt fibre mu urwego rwa asphalt itavangwa n'imvange ya asphalt, ahubwo ihuzwa neza hamwe.
Kurwanya umunaniro: imiterere y'ubutaka bwa basalt mu gice cy'ubuso bwa asphalt, bishobora kuba umuvuduko w'ibiziga hejuru y'umuhanda ndetse no gukwirakwira kw'imitsi yo gukandagira no gukurura, ishyirwaho ry'agace k'ubuhumekero hagati y'uturere tubiri tw'imitsi, impinduka z'imitsi buhoro buhoro aho guhinduka mu buryo butunguranye, bigabanya impinduka zitunguranye z'imitsi ku gice cy'ubuso bwa asphalt. Muri icyo gihe, uburebure buke bwa basalt geogrid bugabanya ihindagurika ry'umuhanda, bigatuma inzira idahinduka cyane.
Uburyo bwo gufunga burwanya ubushyuhe bwinshi: gukoresha imiterere ya basalt geogrid mu gice cya asphalt, bigira uruhare mu gufunga urwego rwa asphalt. Guteranya beto ya asphalt binyuze mu rusobe rw'amazi, bigakora sisitemu yo gufunga ikoresheje ikoranabuhanga, bikagabanya urujya n'uruza rw'ibintu, byongera imbaraga zo gufatanya mu gice cya asphalt, igice cya asphalt cy'igice cya buri gice, bikabuza igice cya asphalt gusunika kugira ngo kigire uruhare rwo kudateranya imiterere.
Kurwanya ubushyuhe buke: mu gihe cy'ubushyuhe buke, beto ya asphalt ikonje igabanuka, bigatuma habaho imbaraga zo gukurura, iyo imbaraga zo gukurura zirenze imbaraga zo gukurura za beto ya asphalt, bigatuma habaho imiyoboro. Basalt geogrid mu gukoresha urwego rw'ubuso bwa asphalt, yongera imbaraga zo gukurura, kugira ngo imbaraga zo gukurura za beto ya asphalt zirusheho kwiyongera, kandi ishobore kurwanya imbaraga zo gukurura cyane nta kwangirika. Byongeye kandi, nubwo bitewe n'agace k'aho imiyoboro iherereye, mu miyoboro igaragaramo imbaraga zo gukurura, binyuze mu kwimura no gusibangana kwa basalt geogrid, imiyoboro ntizahinduka imiyoboro.
Kugabanya imiyoboro igaragara nyuma yo gutinda: muri asphalt hamwe na basalt geogrid flat layer, bigabanya umuvuduko wo gukata cyangwa gukurura bitewe n'imizigo yo mu muhanda, birekura umuvuduko, nk'ibikoresho byo gukomeza imiyoboro igaragara nyuma yo gukata beto, kugira ngo bigere ku ntego yo gutinda kugabanya imiyoboro.

3. Gukoresha geogrid hamwe na fibre y'ibanze
Geogrid mu gushyira mu bikorwa ibintu by'ingenzi birebana n'imbaraga, kurwanya amarira, no guhuza ubutaka, kuramba no ubukungu bwabwo. Kuri ubu, geogrid yakoreshejwe mu rwego rw'umuhanda munini, inzira ya gari ya moshi, ubutaka butemberamo, kongera imisozi, gushyigikira no kubungabunga imiterere, gusana icyuho cy'amabuye, gusana inzira no gukumira no kugenzura icyuho cyo kugarura urumuri. Cyane cyane ikoreshwa rya geogrid mu kongera inzira no gukumira icyuho cyo kugarura urumuri. Icyuho cyo kugarura urumuri ni urwego rw'imizi y'umuhanda bitewe n'impinduka z'ubushyuhe cyangwa umutwaro ufite byinshi cyane bigatuma habaho icyuho, kandi binyuze mu gukwirakwira kw'icyuho hagati y'umuhanda, bigatera intera ihagaze cyangwa itambitse hagati y'icyuho kandi bigatuma ubuso bw'umuhanda bucika. Gukoresha geogrid ifite imikorere myiza bishobora kunoza neza imbaraga zo gukata icyuho hagati y'icyuho no kugorama kw'umuhanda, bigatatanya ubwinshi bw'icyuho, bityo bikarinda ko icyuho cyo kumanuka mu muhanda kibaho, kandi bikagabanya cyane ikiguzi cyo kubungabunga umuhanda. Icyuho cyo kugarura urumuri ni ikintu gikunze kuboneka mu muhanda wa kaburimbo. Ku cyuho cyo kugarura urumuri mu buso bw'umuhanda, gushyira urwego rwa geotextile hagati y'urwego rwa asphalt n'igice cyo munsi bishobora gukuraho cyangwa kugabanya umuvuduko w'icyuho cyo kugarura urumuri mu rufatiro rw'ubutaka, bityo bikongera ubuzima bw'umuhanda. Ariko ubushyuhe bwo kumanuka mu muhanda wa asphalt bugera kuri 160 ℃, bigatuma geotextile cyangwa polymer geogrid zipfundika, zihinduka, zoroha, bityo imikorere yazo igabanuka cyane. Gukoresha geogrid ya asphalt pavement ni byiza gukoresha fibre ya basalt geogrid, kuko fibre ya basalt geogrid ifite ubushobozi bwo kwihanganira ubushyuhe, kandi ifite imbaraga nyinshi, modulus nyinshi, uburebure buke, ingano nto y'ubushyuhe n'ibindi biranga.
