The Trench
Mitemo yenyika uye yedunhu nemirairo yevhu rakavharwaPE mapaipiinofanira kuteverwa panguva yekuvakwa kwemugero unodiwa. Mugero unofanirwa kubvumira zvikamu zvese zvepombi kuti zvinge zviri pakadzika pasina chando uye upamhi hwakakwana.
Trench widths
Tichifunga nezve purojekiti uye mhedzisiro yekuwedzera kune mapaipi kubva pasi, mugero wakafara unofanirwa kuve wakatetepa sezvinobvira.
A rondedzero inokurudzirwa migero yakafara. Aya makoshero anofambirana nemisimboti yekuti hupamhi hwemugero hunofanirwa kuve hwakatetepa sezvinobvira kuitira kuderedza mitoro yekunze nemitengo yekuisa, uku ichipawo nzvimbo yakakwana yekupa iyo yakatsanangurwa compaction.
Iyo yakagamuchirwa chaiyo mugero upamhi huchakanganiswa nemamiriro evhu, majoini masisitimu, uye kana majoini akaitwa mugero.

Pamusoro Ground Installation
CHUANGRONG PE mapaipi anogona kuiswa pamusoro pevhu kuitira kumanikidza uye kusamanikidza kushandiswa mune zvese zviri zviviri kuratidzwa kwakananga uye akadzivirirwa mamiriro. Mapaipi eBlack PE anogona kushandiswa mumamiriro ekubuda kwezuva akananga pasina kumwe kudzivirira. Iko PE mapaipi emavara kunze kwevatema anoshandiswa mumamiriro akafumurwa, ipapo mapaipi anoda kuchengetedzwa kubva kuzuva. Ipo mapaipi ePE akaisirwa mumamiriro ekuratidzwa akananga, ipapo iyo yakawedzera tembiricha yezvinhu zvePE nekuda kwekuratidzwa inofanirwa kuverengerwa mukumisikidza kushanda kwekumanikidza kweiyo PE pombi. Tembiricha yenzvimbo inovaka mamiriro senge padhuze nemitsara yeutsi, ma radiator, kana mashefu emhepo anofanirwa kudzivirirwa kunze kwekunge mapaipi ePE akachengetedzwa zvakafanira. Iko kunoshandiswa zvinhu zvekurembera, izvi zvinofanirwa kunge zvakakodzera zvikumbiro zvekuratidzira.
Zvekubhedha & Backfill
Iyo yakacherwa pasi pemigero inofanirwa kuchekwa, uye ive isina matombo ese, uye zvinhu zvakaomarara. Midziyo yekurara inoshandiswa mumigero uye mumigero ichave imwe yeiyi inotevera:
1. Jecha kana ivhu, risina matombo anopfuura 15 mm, uye chero mapundu evhu akaoma anodarika 75 mm muhukuru.
2. Dombo rakapwanyiwa, hurungudo, kana giredhi zvinhu zvemagiredhi zvine saizi inodarika 15 mm.
3.Zvakacherwa zvisina matombo kana muriwo.
4. Mapundu evhu anogona kuderedzwa kusvika pasi pe75 mm muhukuru.
Muhuwandu hwemashandisirwo epombi yePE, hushoma hwe75mm yemidziyo yekurara inoshandiswa mumigero uye mumigero mukuchera ivhu. Pakucherwa mudombo, hudzamu hwepamubhedha 150 mm hunogona kudiwa.
Chasara chegoronga, kana kuzara kwemupendero zvinogona kugadzirwa nezvinhu zvakacherwa kare.
Izvi zvinofanirwa kunge zvisina matombo makuru, zvinhu zvemuriwo, uye zvinhu zvakasvibiswa, uye zvinhu zvese zvinofanirwa kunge zvine saizi yakakura isingasviki 75 mm.
Ipo mapaipi ePE akaisirwa munzvimbo dzine mitoro yakakwira yekunze, ipapo zvinhu zvekudzosera kumashure zvinofanirwa kunge zviri zvechiyero chakafanana neyemubhedha uye pamusoro pezvinhu.
Thrust Blocks & Pipe Restraint
Mathrust blocks anodiwa kune CHUANGRONG PE mapaipi mukumanikidza kushandiswa uko majoini haarambe kureba mitoro. Mathrust blocks anofanirwa kupihwa panguva dzese shanduko munzira.
Iko kunoshandiswa kongiri zvidhinha, mapoinzi ekusangana pakati pepombi yePE, kana yekukodzera uye iyo thrust block inofanirwa kuchengetedzwa kudzivirira abrasion yePE. Rubber kana malthoid sheeting inogona kushandiswa kune chinangwa ichi.
Zvese zvigadziriso uye zvinhu zvinorema senge simbi yakakandwa mavharuvhu zvinofanirwa kutsigirwa kuitira kudzivirira kurodha kwenzvimbo pane PE zvinhu. Uye zvakare, uko mavharuvhu anoshandiswa, iyo torque mitoro inosimuka kubva pakuvhura / yekuvhara mashandiro inofanira kurwiswa nemabhuroka anotsigira.
Curving yePE Pipelines
Mapaipi ese ePE akaiswa payakakombama anofanirwa kudhonzwa zvakaenzana pamusoro pehurefu hwese curve, uye kwete pamusoro pechikamu chipfupi. Izvi zvinogona kutungamira kune kinking mudiki dhayamita, uye/kana matete emadziro pombi.
Mapaipi mahombe dhayamita PE (450mm uye pamusoro) anofanirwa kubatanidzwa pamwechete, obva akweverwa zvakaenzana kune radius inodiwa. Iyo Minimum inotenderwa bend radius yeHDPE pombi inogona kuwanikwa.
Relining & Non-dig Trench
Mapaipi aripo anogona kuvandudzwa nekuisa CHUANGRONG PE mapaipi mumapombi ekare. Mapombi ekupinza anogona kudhonzwa panzvimbo nemahwindi emuchina. Relining ne PE pombi inopa chimiro chechimiro chinokwanisa kumirisana nekumanikidza kwemukati kana kurodha kwekunze pasina kuvimba nesimba rakasara reiyo yekutanga yakashatiswa pombi zvinhu.
Mapombi ePE anoda kupfupika kwekupinda nekubuda migero kuti agamuchire PE pombi radius kutungamira mupombi iripo, uye gungano rewinch rinoshandiswa kudhonza PE liner parutivi pepombi. Iyo idiki yekubhenda radius yePE liner inogona kuverengerwa sekutsanangurwa pasi pePipeline Curvature yebhuku.
Mapombi ePE anogona zvakare kushandiswa mumapurojekiti asiri ekuchera mugero, akadai seHorizontal Directional Drilling (HDD). Kumwe kushandiswa kwekutanga kwepaipi hombe yePE dhayamita mukuchera kwakananga kwaive kwekuyambuka nzizi. PE pombi inokodzera kuisirwa uku nekuda kwekushivirira kwayo uye yakasanganiswa yekubatanidza sisitimu iyo inopa zero-inodonhedza-chiyero chejoini nedhizaini tensile kugona yakaenzana neyepombi.
Kusvika pari zvino, vadhiraivha vakaisa pombi yePE yegasi, mvura, uye pombi dzesuweji; maconduits emagetsi; uye zvakasiyana-siyana zvemakemikari mitsara.
Zvirongwa izvi zvaisanganisira kwete kungoyambuka nzizi chete asiwo kuyambuka migwagwa mikuru uye maruramiro enzira nomunzvimbo dzakasimukira kuitira kuti zvisavhiringidze migwagwa, nzira dzemotokari, uye panopindwa napo mabhizimisi.
Kugadzirisa uye Kuchengetedza
Zvinoenderana nekukuvadza kwakasiyana, kune marudzi ekugadzirisa matekinoroji ekusarudza. Kugadzirisa kunogona kuitwa pane diki dhayamita pombi nekuvhura yakakwana nzvimbo yemugero uye nekucheka chakaremara. Dzorera chikamu chakakanganisika nechikamu chitsva chepombi.
Kugadzirisa pombi yakakura yedhayamita inogona kuitwa nechidimbu che spool. Chikamu chakakanganisika chinobviswa.Kuzotevera, muchina wekusanganisa butt unodzikiswa mugomba.Makatani eFlanged anosanganiswa kune imwe neimwe yakavhurika magumo, uye iyo flanged spool assembly inosungwa panzvimbo. Iyo flanged spool inofanirwa kugadzirwa nemazvo kuti ikwane mukaha unobuda mupombi.
