Mafambiro Ekuvandudza muKushandiswa kweAkasiyana-siyana Ongororo Matsime Anovhara muUrban Roads

Inspection tsime mavhavha chikamu organic chikamu mumaguta migwagwa. Mukuita kwemaguta, kuvakwa kwemigwagwa chiyero chakakosha chekuyedza mhedzisiro yayo. Zvose kune vashanyi vekunze uye vagari vemo. "Chifukidziro chegomba chakashaikwa" mumvuri, haungangounzi kusagadzikana kwekufamba, asiwo kukonzera tsaona dzinodonha, izvo zvinounza zvakanyanya kukuvadzwa kwemidziyo uye kukuvadzwa kwevanhu. Zvinogona kuonekwa kuti mukuvakwa kwemaguta, maitiro ekugadzira. uye shandisa manhole mavhavha inofanira kuva nyaya yakakosha.

Kuongorora kweChina kwechivharo chemugodhi kwakasangana nematanho matatu, nhanho yekutanga kubva pakati pema1990. Pamberi peizvi, akawanda ekuongorora matsime mavhavha aive akasimbiswa kongiri mhando, nehukuru hwakasiyana; Nekuti pombi yemagetsi haina kuvigwa zvakadzika, hapana chivharo chegomba chinoshandiswa. Mukati memakore ekuma1990, zvivharo zvekongiri zvakasimbiswa zvakatsiviwa nezvivharo zvesimbi. Nekudaro, iyi batch yemanhole inovhara iri nyore kuita ngura nekudonha munzvimbo ine mwando.

Chikamu chechipiri ndechekupera kwema1990, China yakatanga kuvandudza mwero wezvivharo zvemanhole, uye yakatanga kusimudzira kushandiswa kweakakomberedzwa esimbi manhole mavhavha, uye shaft yekuongorora tsime yakashandurwa saizvozvo. Nekuda kweiyo yakanaka corrosion kuramba kwezvinhu zvakakandwa zvesimbi, yakabatana chiyero yakatarwa yakagadzirwa. Naizvozvo, chikamu chakati wandei cheichi batch chekuongorora mabheji chichiri kushandiswa.

Danho rechitatu nderekuti mushure megore ra2008, nekubuda kwezvinhu zvitsva uye tekinoroji yekuisa nyowani, mhando dzemavharo emugodhi mitsva dzinonyanya kusanganisira FRP manhole mavhavha, mavhavha esimbi faibha manhole uye anoumbwa anovharisa manhole, nezvimwewo uye anti-kuba mhedzisiro pane cast iron zvinhu mhando, uye ruzha rwekutsika kwevanhu kana kukunguruka kwemotokari idiki.

Maitiro ekushandisa kweakakanda simbi manhole chivharo

Cast iron inspection yetsime mavhavha ane mhedzisiro yakanaka pakudzivirira ngura, uye akawanda manhole mavhavha achiri akanaka mushure menguva refu yekushandiswa. Nokudaro, inoshandiswa zvakanyanya. Vamwe vagadziri vari kufunga nezvekuwedzera mhete dzerabha kukanda mavharo emakomba esimbi kuderedza ruzha. Kune zvakare vanogadzira kuti vavandudze kukiya kwayo kuitira kugadzirisa dambudziko rekusakwana anti-kuba basa.

Kunyangwe kuongororwa kwezvivharo zvetsime kungaratidzika kushoma mune zano remaguta uye manejimendi. Nekudaro, inzvimbo yakakosha mukutonga kwemadhorobha, iyo yakakosha kune runako rweguta, kuchengetedzwa kwevagari uye kuchengetedzwa kwepombi. Pakuronga kwemadhorobha uye manejimendi, zvinodikanwa kugara uchishandisa zvishandiso zvitsva uye matekinoroji matsva kuongorora mavhavha akanaka uye kusimbisa manejimendi. Panguva imwecheteyo, inogona kukurudzira kurapwa kwe "artistic" yezvivharo zvemanhole, kuitira kuti uwedzere ruvara rwakajeka kune kuchengeteka, nyore uye kunaka kweguta.

Mazwi akakosha: kuvakwa kwemadhorobha, manejimendi emigwagwa, tarisa chivharo chetsime, hupenyu hwemaguta
