Yog vim li cas yog manhole npog puag ncig - nws yog ib tug yuav tsum los yog kev lig kev cai?

Yog vim li cas yog manhole npog puag ncig? Thiab yog dab tsi lawv yuav tseem yuav? Raws, lub daug yuav ua tau square los yog rectangular zoo. Tab sis xws li ib tug tsim, es - tsis suav rau hauv txoj cai. Hatch - tsis yog ib qho yooj yim qhov, nws yuav tsum tau securely kaw. Nws yuav tsum muaj ib qho yooj yim mus ua hauj lwm thiab kev nyab xeeb siv.

Yog hais tias yooj yim - nws yog ib qho kev pib xyaum ua, nyob rau ntxawg theem, lub ntseeg ntawm load nws yuav muab puag ncig hau tsim. Nws yog nyob ntawm tus duab ntawm lub hauv paus configuration uas, nyob rau hauv qhov tseeb, yog ib tug phwj manhole.

dej system

Sewer network - ib tug complex ntawm vaj tse tsim los rau cov sau thiab tshem tawm ntawm wastewater los ntawm cov kev kho mob chaw rau cov neeg siv. Qhov no yog feem ntau yooj yim ua nrog rau cov kev pab los ntawm underground hlauv taws xob. Khawb ib trench, nws nteg cov yeeb nkab, uas yuav tsum tau tawm wastewater.

Yuav tsum tau kev pab rau hauv lub system tom qab ib tug tej yam deb tsim nyog kev soj ntsuam ntawm cov mine. Nyob rau hauv cov nqe lus ntawm lub nroog infrastructure nrog tuab tsev lub sij hawm mus sewers tsuas nrog txoj kev los ncaj qha rau hauv qab rau lawv. Nyob rau hauv cov ntaub ntawv no, lub vehicular tsheb hatches yuav tsum tau securely kaw. Tab sis yog vim li cas yog manhole npog puag ncig? Lawv yuav tsum muaj lub zog txaus los mus tiv lub siab tshaj plaws tau thauj load.

Nyob rau hauv lub nroog loj tus xov tooj ntawm manholes thiab tag nrho cov hom ntawm mines yuav yog pua pua txhiab. Nws tsis yog tsuas yog kav dej phwj, yog tseem network ntawm kev sib txuas lus: dej, cua kub, hluav taws xob, roj, xov tooj thiab thiaj li nyob.

manholes

Rau yooj yim nkag tau mus rau lub kev sib txuas lus ntawm lub zoo ncej feem ntau yog nqa tawm ib puag ncig puab. Rings phwj siv rau lub erection ntawm xws lug, feem ntau ua los ntawm kev reinforced.

Cov cylindrical zoo ntawm lub qhov dej no feem ntau haum rau cov kev pab cuam. Nyob rau hauv cov mines ua ntau xis ua hauj lwm. Lawv yog cov tsim rau qhov cua, txij thaum lub ncig ntawm huab cua nyob rau hauv tus kwv uas cylindrical zoo yog ntau khaus.

Qhov luaj li cas ntawm lub hau cheeb tsam ntawm lub hauv paus thiab ib puab inch xaiv raws li lub hom phiaj ntawm saib tus ncej. Nyob rau hauv cov ntaub ntawv no, tag nrho cov ntsiab ntawm lub kaw lus yuav yog tus tseem zoo ib yam. Nws yuav siv sij hawm mus rau hauv tus account lub qhov chaw, tau load, tsheb siv.

Yog vim li cas yog manhole npog puag ncig?

Nws nyob ntawm qhov zoo ntawm lub hau. Nyob rau hauv ib tes, cov neeg ua hauj lwm yuav tsum muaj ib qho yooj yim nkag tau mus rau underground hlauv taws xob. Nyob rau lwm cov tes, cov zoo yuav tsum tau securely kaw los mus tiv thaiv tej ingress ntawm txawv teb chaws tej khoom, los xyuas kom meej qhov muaj kev nyab xeeb zog ntawm cov neeg taug kev thiab tsav tsheb tsheb. Round hau zoo tshaj plaws haum rau qhov no, thiab yog li ntawd nws yuav tsum yog ib tug daug lawm.

Nyob ntawm seb lub hom phiaj lawv muab faib raws li cov hom kev sib txuas lus, nteg nyob rau hauv lawv: engineering cable tes hauj lwm, dej haus, roj pipelines, cua sov mains, cua daj cua dub thiab dej khib nyiab kua. Qhov luaj li cas ntawm ib tug manhole nyob rau hauv ntau lub teb chaws sib txawv. Nyob rau hauv Russia, tus qauv loj (645 thiab 800 hli) yog feem ntau siv. Hatches, ua tsis los ntawm lub xeev cov qauv, tsim thiab tsim los ntawm manufacturers nyob rau hauv raws li qhov kev txiav txim thiab tej kev uas yuav tsum tau.

Yog vim li cas yog ib tug manhole npog puag ncig?

Qhov no configuration muaj ob peb zoo. Yav tas los hatches tau ua los ntawm ntau daim. Lawv yuav ua tau square, rectangular, oval thiab txawm daim duab peb sab yuav qhia tau cov kev taw qhia ntawm cov dej ntws. Txawm li cas los, cov hloov puab ntawm lub hau muab tau lub feem ntau tsim nyog.

Nws yeej tsis nyob rau hauv lub zoo, raws li yog hais tias nws twb tsis muab. Ib tug yeej hau yooj yim qhib, li ntawd, tus quab yuam daim ntawv thov point nyob qhov twg lub vajvoog yuav tau tib yam. Nws muaj peev xwm yuav dov, muab tso rau hauv ntug. Nyob rau hauv lub chaw ua khoom ntawm xws li ib tug qauv yog kev lag kev luam ntau muaj txiaj ntsim.

Lub round zoo ntawm lub hau yog tsawg yuav raug subsidence. Nws muaj peev xwm mas ib tug ntau dua load nrog tib thickness, uas txhais tau tias nws yuav ua tau thinner tsis tau poob zoo. Nyob rau hauv zus tau tej cov round castings muaj ib sab feem pua ntawm cov tsis xws luag (kab noj hniav, pores, kab noj hniav).

cov ntaub ntawv uas

Lub hauv paus thiab lub manhole npog rau kev manholes no feem ntau yog ua los ntawm cam khwb cia hlau. Qhov no cov ntaub ntawv uas muaj ib lub zog, uas enables load nqa thiab corrosion kuj rau ib ntev lub pab lub neej. Nyhav lug txaus thauj tus traveler yuav tsis mej tsa thiab xaub cover. Cam khwb cia hlau npog yog ua nyob rau hauv lub smelting ntawm ob raw cov ntaub ntawv, lawv yog cheaper steel counterparts.

Nyob rau hauv qhov chaw nyob qhov twg muaj tsis muaj vehicular tsheb, nruab hnyav thiab muaj hwj chim loj tsim yus. Tsis ntev los no muaj yas hatches, polymers thiab puas cov ntaub ntawv. Lawv yog cov yooj yim, pheej yig dua, muaj ib tug txaus paj tau paj ntawm kev ruaj ntseg, ntev kev pab cuam lub neej.

Nyob rau hauv private tsev txhua yam rau dej kua, cov khoom manholes thiab lub taub dej khawb tso tsheb hlau luam dej siv rings ua los ntawm kev reinforced. Nyob rau hauv cov ntaub ntawv no nws yog justified teem rau sab saum toj ntawm lawv tib lub hauv paus rau lub daug. Lub cover yog tseem manufactured los ntawm qhob. Nws yog ib tug loj inch, nws tsis yog muaj nyob rau hauv lub zawj, tab sis tsuas yog muab kaw qhov qhib ntawm lub daug. Loj heev kev tsim kho yog hnyav txaus, nws yuav tsis ntawd txav. Nws muab cov tsim nyog muaj kev ruaj ntseg thaum lub sij hawm lub lag luam.

Specification thiab labeling

hnyav hatches (cov chav kawm ntawv T) yog siv los txhim kho tsheb loads. Tej zaum lawv yuav muaj ib tug luj ntawm 100 kg thiab ib tug tuab ntawm ntau tshaj 100 hli. Qhov twg yog tsis muaj vehicular tsheb yog muab siv lub teeb hatches (A class). Siv lub vaj, lawns thiab lwm qhov chaw (cov chav kawm ntawv A) muaj ib lub cheeb ntawm 540 hli thiab ib tug tuab ntawm 50 mm.

Yog vim li cas yog manhole npog puag ncig thiab cov cim? Qhov no yog ua li cas rau lub yooj yim ntawm cov paub txog lawv koom rau lub hlauv taws xob. Nyob rau lawv kaus mom imyutsya tsiaj ntawv: GS - gas network, MG - gas ntsiab GHG - hluav taws kub hydrant, etc.
