1. Kumenyekanisha no gutondekanya kwikorera-sima / minisiteri
Kwishyira hejuru ya sima / mortar ni ubwoko bushobora gutanga igorofa iringaniye kandi yoroshye hejuru yanyuma (nka tapi, hasi mubiti, nibindi).Ibikorwa byingenzi byingenzi bisabwa harimo gukomera byihuse no kugabanuka guke.Hano hari sisitemu zo hasi zitandukanye kumasoko nka sima, gypsumu cyangwa imvange zabo.Muri iyi ngingo tuzibanda kuri sisitemu zitemba zifite imiterere iringaniye.Ubutaka bwa hydraulic butemba (niba bukoreshwa nkurwego rwa nyuma rutwikiriye, byitwa ibikoresho byo hejuru; niba bikoreshwa nkurwego rwinzibacyuho rwagati, byitwa ibikoresho byo kwisiga) muri rusange byitwa: sima ishingiye ku kwishyira hejuru. igorofa (hejuru yubuso) hamwe na sima ishingiye kurwego rwo hasi (cushion layer)).
2. Ibicuruzwa byibigize nibipimo bisanzwe
Kwishyira hejuru ya sima / minisiteri ni hydratulike ikomye yibikoresho bikozwe muri sima nkibikoresho fatizo kandi byuzuzanya cyane nibindi bikoresho byahinduwe.Nubwo formulaire zitandukanye ziboneka kurubu ziratandukanye kandi ziratandukanye, ariko muri rusange ibikoresho
Ntibishobora gutandukana nubwoko bwerekanwe hepfo, ihame ni rimwe.Igizwe ahanini nibice bitandatu bikurikira: ibipimo bisanzwe bya bamwe mubakora.

.Isubiranamo rya rubber ifu irusheho kunoza imitekerereze kandi igatanga imbaraga.
4. Ibicuruzwa byiza bisabwa hamwe nikoranabuhanga ryingenzi
4.1.Ibisabwa byibanze byo kwishyiriraho sima / minisiteri
(1) Ifite amazi meza, kandi ifite umutungo uringaniza mugihe cya milimetero nkeya, kandi
Igicucu gifite ituze ryiza, kuburyo gishobora kugabanya ibintu bibi nko gutandukanya, gutandukanya, kuva amaraso, no kubyimba.
Kandi birakenewe kwemeza igihe gihagije cyakoreshwa, mubisanzwe iminota irenga 40, kugirango byorohereze ibikorwa byubwubatsi.
(2) Uburinganire ni bwiza, kandi hejuru nta nenge zigaragara.
:
Imikorere igomba kuba yujuje ibisabwa byubatswe muri rusange.
(4) Kuramba ni byiza.
(5) Ubwubatsi buroroshye, bwihuse, butwara igihe kandi butanga akazi.
4.2.Ibikoresho byingenzi bya tekiniki yo kwishyiriraho sima / minisiteri
(1) Kugenda
Amazi ni ikimenyetso cyingenzi kigaragaza imikorere ya sima / marimari.Mubisanzwe, amazi arenze 210-260mm.
(2) Guhagarara neza
Iyi ngengabihe ni indangagaciro igaragaza ituze rya sima / minisiteri.Suka ibishishwa bivanze ku isahani yikirahure ishyizwe mu buryo butambitse, witegereze nyuma yiminota 20, ntihakagombye kubaho kuva amaraso bigaragara, gusibanganya, gutandukanya, kubyimba nibindi bintu.Iyi ndangagaciro ifite uruhare runini kumiterere yubuso no kuramba kwibikoresho nyuma yo kubumba.
(3) Imbaraga zo guhonyora
Nkibikoresho byubutaka, iki kimenyetso kigomba kubahiriza ibisobanuro byubwubatsi bwa etage ya sima, inzu isanzwe ya sima isanzwe.
Imbaraga zo kwikuramo igorofa ya mbere isabwa kuba hejuru ya 15MPa, naho imbaraga zo kwikuramo hejuru ya sima hejuru ya 20MPa.
(4) Imbaraga zoroshye
Imbaraga zihindagurika zinganda zo kwishyiriraho sima / minisiteri igomba kuba irenze 6Mpa.
(5) Igihe cyo guterana
Mugihe cyo gushiraho sima / minisiteri yo kwishyiriraho, nyuma yo kwemeza ko ibishishwa bingana, menya neza ko igihe cyo kuyikoresha kirenze iminota 40, kandi imikorere ntizagira ingaruka.
(6) Kurwanya ingaruka
Kwishyira hejuru ya sima / minisiteri igomba kuba ishobora guhangana ningaruka zumubiri wumuntu hamwe nibintu bitwarwa mumodoka isanzwe, kandi kurwanya ingaruka zubutaka birarenze cyangwa bingana na joules 4.
(7) Kwambara ukurwanya
Kwiyubaka-sima / minisiteri nkibikoresho byubutaka bigomba kwihanganira ibinyabiziga bisanzwe.Bitewe nuburinganire bwacyo buringaniye, iyo ubutaka bwubutaka bukomeye, imbaraga zayo zifata cyane cyane hejuru, ntabwo ari mubunini.Kubwibyo, kwihanganira kwambara ni ngombwa kuruta imbaraga zo kwikuramo.
(8) Huza imbaraga zingana kurwego shingiro
Imbaraga zo guhuza hagati yo kwishyiriraho sima / mortar hamwe nigitereko fatizo bifitanye isano itaziguye no kumenya niba hazaba umwobo no kugwa nyuma yo gukomera, bigira ingaruka zikomeye kumara igihe cyibikoresho.Mubikorwa nyabyo byubwubatsi, kwoza hasi yubutaka kugirango ubashe kugera kumiterere ikwiranye nubwubatsi bwibikoresho.Guhuza imbaraga zingirakamaro za sima yo murugo ibikoresho byo kuringaniza bisanzwe biri hejuru ya 0.8MPa.
(9) Kurwanya
Kurwanya Crack nikimenyetso cyingenzi cyerekana kwipima sima / minisiteri, kandi ubunini bwayo bujyanye no kumenya niba hari ibice, gutobora, no kugwa nyuma yibikoresho byo kwikuramo bigoye.Niba ushobora gusuzuma neza ukurwanya kwangirika kwibikoresho byo kuringaniza bifitanye isano nimba ushobora gusuzuma neza intsinzi cyangwa kunanirwa kwibikoresho byo kwipimisha.
5. Kubaka ubwisanzure bwa sima / minisiteri
(1) Ubuvuzi bwibanze
Sukura urwego shingiro kugirango ukureho umukungugu ureremba, irangi ryamavuta nibindi bintu bidahuza.Niba hari ibinogo binini murwego rwibanze, kuzuza no kuringaniza birakenewe.
(2) Kuvura hejuru
Koresha amakoti 2 yubutaka bwa interineti hasi hasi.
(3) Kuringaniza ubwubatsi
Kubara ingano y'ibikoresho bitandukanye ukurikije ingano y'ibikoresho, igipimo gikomeye cy'amazi (cyangwa igipimo gikomeye cy'amazi) hamwe n'ahantu ho kubaka, koga neza hamwe na mixer, usukemo ibishishwa bivanze hasi, hanyuma ukureho buhoro buhoro ibyatsi.
(4) Kubungabunga
Irashobora kubungabungwa ukurikije ibisabwa mubikoresho bitandukanye byo kuringaniza.
