Kugeza ubu, nta bipimo ngenderwaho birambuye by’igihugu byubaka inganda zivunika, ariko hariho ibipimo bigaragara byo kugenzura no gutahura ibikoresho bitandukanye bivunika mu rwego rw’igihugu GB / T ku bikoresho byangiritse.Urashobora kwifashisha ibipimo ngenderwaho kugirango upime ubwubatsi bwa castable.Reka tubaganire muri make.
Ibikoresho byinshi bishobora kugenzurwa no kugeragezwa ukurikije uburyo busanzwe bwigihugu bwo gupima uburyo bwo kwagura ubushyuhe bwibikoresho bivunika (GB / T7320).Ibikoresho byangiritse bigomba gusukwa hakurikijwe ingingo zikurikira:
1. Ahantu hubatswe hagomba kubanza gusukurwa.
2. Iyo ibishishwa bivunika bivanze n'amatafari yangiritse cyangwa ibicuruzwa bitanga ubushyuhe, hazafatwa ingamba zo kurwanya amazi kugirango ziherere.Mugihe cyo kubaka, imbaho zifuro hamwe nigitambaro cya pulasitike birashobora gukoreshwa mu kubitandukanya, kandi birashobora gukurwaho nyuma yo kubaka.
Uruganda rukora ibicuruzwa rurakwibutsa ko ubuso bwibikorwa bikoreshwa mugusuka itanura bigomba kuba byoroshye, hamwe no gukomera nimbaraga zihagije, kandi gushiraho no gukuraho impapuro zifite imiterere yoroshye bigomba kuba byujuje ibi bikurikira:
1. Inkunga igomba gushyirwaho kandi igakurwaho kugirango byoroherezwe kumeneka.Ibiti bikozwe mu giti bigenewe kwaguka bigomba gushyirwaho neza kugirango birinde kwimuka mugihe cyo kunyeganyega.
2. Kubintu byangiritse bifite ruswa cyangwa gufatana hamwe, hashyirwaho urwego rwo kwigunga kugirango rufate ingamba zo kurwanya ubufatanye, kandi gutandukana kwemererwa gutandukanya uburebure bwikigereranyo ni + 2 ~ - 4mm.Impapuro ntizishobora gushyirwaho kumasuka yasutswe mugihe imbaraga zayo zitageze kuri 1.2MPa.
3. Impapuro zishobora gushirwaho mu buryo butambitse mu bice no mu bice cyangwa mu bice bitandukanye.Uburebure bwa buri cyuma cyubatswe bugenwa hakurikijwe ibintu nkubushyuhe bwibidukikije busuka umuvuduko wikibanza cyubatswe nigihe cyo kugena abaterankunga.Mubisanzwe, ntibishobora kurenga 1.5m.
4. Impapuro zikorera imitwaro zizakurwaho iyo castable igeze kuri 70% yimbaraga.Impapuro zidafite imitwaro zigomba gukurwaho mugihe imbaraga zishobora guterwa neza ko itanura ryubatswe hamwe nu mfuruka bitazangirika kubera gusenyuka.Ibikoresho bishyushye kandi bikomeye bigomba gutekwa kubushyuhe bwagenwe mbere yo kubikuraho.
5. Ingano yubunini, umwanya wo gukwirakwiza nuburyo bwo kwaguka bihujwe hamwe n’itanura ryuzuye ryuzuye bigomba kubahiriza ibishushanyo mbonera, kandi ibikoresho byuzuzwa hakurikijwe ibishushanyo mbonera.Iyo igishushanyo kitagaragaza ubunini bwikinyuranyo cyo kwaguka, impuzandengo yagutse yo kwaguka kuri metero imwe yumuriro.Ubuso bwagutse kumurongo wumucyo wangiritse urashobora gushyirwaho mugihe cyo gusuka cyangwa gukata nyuma yo gusuka.Iyo itanura rifite uburebure burenze 75mm, ubugari bwumurongo wo kwaguka bugomba kuba 1 ~ 3mm.Ubujyakuzimu bugomba kuba 1/3 ~ 1/4 cy'itanura rifite uburebure.Umwanya wo kwagura umurongo ugomba kuba 0.8 ~ 1m ukurikije imiterere y'iriba.
6. Iyo umubyimba wogukoresha insimburangingo ziterwa na mm 50mm, uburyo bwo gutwikira intoki burashobora kandi gukoreshwa mugukomeza gusuka no gutobora intoki.Nyuma yo gusuka, hejuru yumurongo hagomba kuba haringaniye kandi huzuye nta gusya.
Umubyimba wumucyo utanga urumuri rushobora kwangirika δ <200mm, hamwe nibice bifite aho bihurira hejuru yitanura ritarenga 60 birashobora gusukwa mukiganza.Iyo isuka, igomba kugabanwa neza kandi igasukwa ubudahwema.Inyundo ya rubber cyangwa inyundo yimbaho bizakoreshwa muguhuza ibice hamwe ninyundo imwe nigice cyinyundo muburyo bwa plum.Nyuma yo guhuzagurika, icyuma gishobora kwerekanwa kizakoreshwa mu kunyeganyega no guhuza itanura hejuru.Itanura rifite itanura rigomba kuba riringaniye, ryuzuye kandi ridafite uduce duto duto.
