Ibiranga nibyiza byo guteramo ibyuma bifata ibyuma bifata ibyuma
Ibipimo bifatika byerekana imbaraga zingutu, kurambura, imbaraga zitanga umusaruro, hamwe numutwe wumutwaro urenze hejuru cyane ugereranije nibisanzwe bitwikiriye ibyuma.
Igikoresho cyo kurwanya ubujura gihujwe nu mwobo uhamye, uruzitiro rwamasoko, hamwe namakarita yo gukosora.Mugihe cyo gufungura, gufunga byabigenewe bigomba kwinjizwamo no kuzunguruka 90 ° kumasaha kugirango amasaha yemererwe gusohoka.Irashobora guhita ifunga muburyo bworoshye, butekanye, kandi bwizewe.
Iyo uzamuye hejuru yumuhanda, igifuniko cya manhole gisukwa hejuru yumuhanda hejuru yikigero cyo hanze, kandi nta mpamvu yo gucukura ibifuniko byose bya manhole mugihe cyo kuyishyiraho.
Bitewe no gukoresha polichlorine ether padi hejuru yuburinganire bwikigero no gutwikira, ubujyakuzimu bukwiranye hagati yikigero nigifuniko byiyongereye.Guhuza ingingo esheshatu zikoreshwa kugirango hamenyekane neza hagati yikintu nigipfukisho, kandi impeta zikoreshwa mugukuraho urusaku no kugabanya kunyeganyega.
Mu rwego rwo kwemeza neza, igifuniko cya manhole cyahujwe nubuso bwumuhanda kugirango bigere ku ngaruka zo gutunganya umujyi.
Icyitonderwa cyo Gushiraho Amashanyarazi ya Ductile
1. Kugirango uzamure imbaraga zo guhonyora impeta y'iriba no kongera umwanya wicara hejuru yubutaka bwimpeta y'iriba, diameter y'imbere yumubiri w iriba ntigomba kuba irenze diameter yimbere yimpeta y'iriba mugihe ushyira iriba impeta.
2. Imiterere yurubuga rwiriba rugomba kuba rufite amatafari yubakishijwe amatafari, agomba kuba akomeye kandi aringaniye kugirango agire imbaraga zubaka mbere yo gushiraho impeta yiziba hamwe nintebe.
3. Mugihe ushyiraho urusyo, hejuru yubuso ntigomba guhagarikwa.Urashobora kwifashisha uburyo bwo kwishyiriraho impeta nziza.
4. Iyo ushyize impeta y'iriba hamwe n'intebe yo gusya, bigomba gushyirwa ahantu mbere yuko beto iri munsi yimpeta yiziba hamwe nintebe ya grake (uburebure bwa beto ntibugomba kuba munsi ya 30mm), kandi impeta yiziba igomba guhuzwa. cyangwa kunyeganyezwa n'imbaraga zo gukora iriba hamwe na beto bifatanye neza, kugirango wongere ubuso bwubusabane hagati yimpeta iriba hamwe nintebe yo gusya hamwe na platifomu.
5. Ubushobozi bwo kwikorera ibicuruzwa nyuma yo kwishyiriraho ntibishobora kurenza ubushobozi bwihariye bwo gutwara ibicuruzwa.
6. Mbere yo gushiraho igifuniko, kura imyanda iyo ari yo yose kuriba kugirango wirinde guhuza igifuniko n'iriba.
7. Fungura ukoresheje igikoresho kidasanzwe.
8. Iyo igifuniko cya manhole hamwe nigituba cyamazi yimvura kidashyizwe mumwanya, bigomba gushyirwa ahantu hizewe kugirango ibinyabiziga bitagenda.
9. Kurikiza byimazeyo ibisabwa byavuzwe haruguru kugirango ushyireho, bitabaye ibyo ntabwo tuzakora inshingano.
