Usoro mmepe na ntinye nke mkpuchi ọma nyocha dị iche iche n'okporo ụzọ obodo

Ihe mkpuchi olulu mmiri nyocha bụ akụkụ organic nke okporo ụzọ mepere emepe. N'ime usoro ime obodo, iwu okporo ụzọ bụ ụkpụrụ dị mkpa iji nwalee nsonaazụ ya. Ma maka ndị ọbịa si mba ọzọ na ndị bi na mpaghara. "Mkpuchi manhole na-efu efu" bụ onyinyo, nke na-agaghị eweta nsogbu na njem njem, ma na-ebutekwa ihe mberede na-ada ada, nke ga-eweta nnukwu mmebi ihe onwunwe na mmerụ onwe onye. Enwere ike ịhụ na n'ime usoro iwu obodo, otu esi emebe na iji ihe mkpuchi manhole kwesịrị ịbụ isiokwu dị mkpa.

Nlele China na-ekpuchi ihe mkpuchi olulu ahụ enwetala nkebi atọ, nke mbụ site na etiti 1990s. Tupu nke a, ọtụtụ n'ime mkpuchi olulu mmiri nyocha bụ ụdị ihe a na-emesi ike, nke nwere nha dị iche iche; Ebe ọ bụ na a naghị eli ọkpọkọ ọkụ ahụ nke ọma, ọ dịghị ihe mkpuchi oghere ọ bụla. N'etiti 1990s, e ji ihe mkpuchi igwe dochie anya ọtụtụ ihe mkpuchi ihe mkpuchi ụlọ siri ike. Otú ọ dị, ihe mkpuchi nke oghere a na-adị mfe nchara ma daa na gburugburu ebe iru mmiri.

Nkeji nke abụọ bụ njedebe nke 1990s, China malitere ịmepụta ọkọlọtọ nke mkpuchi mkpuchi, ma malite ịkwalite iji ihe mkpuchi nkedo nkedo gburugburu, na ogwe nke nyocha nke ọma gbanwere otú ahụ. N'ihi ezigbo nguzogide corrosion nke ihe nkedo, a haziri nkọwapụta ọkọlọtọ jikọtara ọnụ. Ya mere, a ka na-eji akụkụ dị ukwuu nke ihe mkpuchi olulu mmiri a.

Usoro nke atọ bụ na mgbe afọ 2008 gasịrị, site na mmepụta ihe ọhụrụ na teknụzụ ntinye ọhụrụ, ụdị ihe mkpuchi ọhụrụ na-agụnye FRP manhole cover, ígwè fiber manhole cover na composite manhole cover, wdg. Ndị a na-ekpuchi oghere nwere mma mgbochi corrosion. na mmetụta mgbochi izu ohi karịa ụdị ihe nkedo ígwè, na ụda nke ịzọda mmadụ ma ọ bụ ịgbagharị ụgbọ ala dị ntakịrị.

Ngwa ngwa nke ihe mkpuchi igwe nkedo

Ihe mkpuchi nkedo nkedo nke ọma na-enwe mmetụta dị mma na nguzogide corrosion, na ọtụtụ mkpuchi manhole ka dị mma mgbe ejiri ogologo oge mee ihe. Ya mere, a na-ejikarị ya eme ihe. Ụfọdụ ndị na-emepụta ihe na-atụle ịgbakwụnye mgbanaka rọba iji wụnye ihe mkpuchi ígwè iji belata mkpọtụ ha. E nwekwara ndị na-emepụta ihe na-emeziwanye mkpọchi ya iji dozie nsogbu nke ọrụ mgbochi ezughi oke.

Ọ bụ ezie na nyocha nke mkpuchi nke ọma nwere ike iyi ihe na-adịghị mkpa na ndụmọdụ na nlekọta obodo. Otú ọ dị, ọ bụ akụrụngwa dị mkpa na njikwa obodo, nke dị mkpa maka ịma mma nke obodo, nchekwa nke ụmụ amaala na nchebe nke pipeline. Maka nhazi na njikwa obodo, ọ dị mkpa iji ihe ọhụrụ na teknụzụ ọhụrụ na-eme ihe mgbe niile iji nyochaa mkpuchi nke ọma na iwusi njikwa ike. N'otu oge ahụ, ọ nwere ike ịkwado ọgwụgwọ "ihe nka" nke mkpuchi manhole, ka ọ wee tinye agba na-egbuke egbuke na nchekwa, ịdị mma na ịma mma nke obodo ahụ.
