Plastic cast iron manhole anovhara chinhu chakakosha chinowanikwa mumigwagwa yemudhorobha nenzvimbo dzeveruzhinji.Nzira dzakasiyana-siyana dzavanogona kushandiswa uye zvakakosha zvakakosha zvezvivharo zvegomba izvi zvakagadzirwa nesimbi yakakandwa zvinovaita sarudzo yekutanga mumunda wezvivharo zvegomba.
Maitiro ekugadzira echifukidzo chegomba akakosha zvakanyanya, uye chivharo chepurasitiki chakakandwa chesimbi chinotora nzira yekukanda.Izvi zvinogadzira mavharo emugodhi wesimbi nokudira simbi yakanyunguduka muforoma uye kubvisa chakuvhe pashure pokunge chatonhora nokuoma.Anotevera ndiwo nhanho huru mukugadzirwa kweanogoneka cast iron manhole anovhara.
Kutanga, kuumbwa kwekugadzira kugadzira kuumbwa kunogadzirwa.Molds dzinowanzo gadzirwa nejecha rakagadzirwa zvakanyanya rinokwanisa kumira kutonhora kwakanyanya uye kuchengetedza kunaka kwechigadzirwa chekupedzisira.Zvadaro, dururira mvura yakakandwa simbi muforoma.Iyi nzira inoda kunyatso kudzora tembiricha uye chiyero chekudira kuti ive nechokwadi chemhando uye kuvimbika kwekukanda.
Zvadaro, simbi yakakandwa inoda kutonhora uye kusimba.Izvi zvinogona kuwanikwa nekurega mold igare kwenguva yakati pane tembiricha isingaperi.Nguva yekutonhora uye yekurapa zvinoenderana nehukuru hwechivharo chegomba uye nezvinodiwa zvechigadzirwa.Chinangwa chedanho iri ndechekuona kuti simbi yakakandwa yakanyatsogadziriswa uye ine kuoma kunodiwa uye simba.
Pakupedzisira, chifukidziro chesimbi chakakandwa chinoda kubviswa kubva muforoma uye kugadziridzwa gare gare.Kazhinji, pachange paine zvakasara pachivharo chemugodhi zvinoda kubviswa pasati paitwa mushonga wepamusoro kana kurapwa kwekupisa kuti iwedzere kusamira kwemamiriro ekunze uye kusaita ngura.Chigadzirwa chekupedzisira chinoda kuongororwa kwemhando kuti ive nechokwadi chekutevedzera zvinoenderana nemitemo yenyika uye zvinodiwa.
Iyo yekukanda nzira inoshandiswa kune inogoneka cast iron manhole mavhavha ine akati wandei akakosha mabhenefiti.Heano mashoma mashoma mabhenefiti:
1. Kugara kwenguva refu: Zvivharo zvesimbi zvinogoneka zvinogoneka zvine kusimba uye kusimba.Ivo vanokwanisa kumirisana nekuremerwa kwakawanda uye kazhinji traffic, zvichiita kuti ive yakakodzera kushandiswa mumigwagwa nenzvimbo dzeveruzhinji.
2. Kuchengetedzwa: Iyi mhando yevhavha yemugodhi ine yakanakisa kuchengetedza kuita.Mamiriro avo epamusoro uye magadzirirwo anogona kupa yakanaka anti-slip athari, kuderedza njodzi yekukuvara kune vanofamba netsoka uye mota nekuda kwekutsvedza.
3. Corrosion resistance: Plastic cast iron manhole mavhavha ane simba rekusagadzikana kumakemikari nemvura munzvimbo.Izvi zvinovabvumira kuita zvakanaka mumamiriro ekunze emvura uye akaoma.
4. Economical: Zvichienzaniswa nezvimwe zvinhu, mutengo wekugadzira wepurasitiki cast iron manhole anovhara wakaderera.Izvo zviri nyore kugadzira uye zvisingadhure mumidziyo, zvichiita kuti ive sarudzo yakasarudzika yemaguta mazhinji uye masangano everuzhinji.
5. Plasticity: Maitiro ekukanda epurasitiki cast iron manhole anovhara anogona kuona maumbirwo akaomarara uye magadzirirwo.Izvi zvinopa vagadziri vezvivharo zvemugodhi nerusununguko rwakakura rwekugadzirisa zvivharo zvemugodhi mumhando dzakasiyana uye saizi zvichienderana nezvinodiwa chaizvo.
Muchidimbu, mapurasitiki akakandwa esimbi manhole anovhara anogadzirwa nekukandira maitiro, ayo ane akawanda mabhenefiti akadai sekusimba, kuchengeteka, kusadzivirirwa nekuora, hupfumi uye plastiki.Aya mabhenefiti anoita kuti gomba resimbi rakakandwa rivhare sarudzo yakajairika yekuvharisa manhole mumaguta uye inoshandiswa zvakanyanya munzvimbo zhinji dzeveruzhinji.Ingave mugwagwa kana nzira yemugwagwa, chivharo chepurasitiki chakakandwa mugomba chinogona kupa ruzivo rwakanaka rwemushandisi uye vimbiso yekuchengetedza veruzhinji.
