Cov kav dej phwj tuaj, zoo li lwm yam, yog tsim los ntawm cov khoom sib txawv uas tau tsim los ua kom muaj kev ua haujlwm tau zoo tshaj plaws. Cov no suav nrog manholes, uas tsim nyog rau kev saib xyuas thiab kev saib xyuas ntawm lub xeev ntawm lub system. Kev npaj ntawm manholes yuav tsum tau thaum hloov txoj kab nqes ntawm cov khoom sau, txoj kab uas hla ntawm cov kav dej thiab lawv cov kev taw qhia.

Ntau yam manholes

Kev tshuaj xyuas qhov dej, nyob ntawm tus qauv tsim, tej zaum yuav yog ib hom. Ntawm lawv nws yog ib qho tsim nyog kom paub qhov txawv: linear, teb, nodal, tswj, ntxuav, sib txawv, nrog rau cov uas muaj qhov loj qhov ntev ntawm lub hatch. Linear yog nyob rau ntawm cov kab ncaj nraim, cov rotary yog siv nyob rau hauv cov chaw uas cov kav dej phwj hloov nws cov kev taw qhia. Lub qhov dej nodal nyob rau hauv cov chaw uas muaj ob peb ceg txuas. Xws li ib tug node yuav tsis muaj ntau tshaj peb inlet thiab ib lub qhov hluav taws xob yeeb nkab. Yog hais tias peb tham txog ib tug loj collector, ces tus tsim yog hu ua lub connecting chamber. Tswj lub qhov dej yuav tsum tau nruab rau hauv cov chaw uaskev sib txuas ntawm lub vaj, lub Hoobkas, nrog rau kev sib txuas hauv lub quarter rau txoj kev. Lub qhov dej ntxuav yog nyob rau hauv thawj qhov chaw uas muaj sedimentation yog ua tau vim qhov qis tshaj. Lawv qhov kev xav tau tshwm sim thaum xav tau cov kav dej.

Tsim

Manholes yuav yog ib hom, tab sis feem ntau muaj cov qauv tsim zoo sib xws. Lawv suav nrog cov hauv qab no: caj dab, tais, hatch, ua haujlwm chamber thiab hauv paus. Lawv tuaj yeem ua los ntawm cov ntaub ntawv sib txawv, xws li: yas, cov pob zeb muaj zog, cib lossis pob zeb. Yog hais tias lub qhov dej nyob rau ntawm qhov chaw uas tsis muaj pavement, ces nyob ib ncig ntawm kev tsim kho ntawm lub qhov muag tsis pom kev, nws yog ib qho tsim nyog yuav tau ua kom cov dej ntws zoo. Kev tshuaj xyuas qhov dej nyob rau hauv cov nqe lus ntawm feem ntau muaj cov duab ntawm ib daim duab plaub los yog lub voj voog. Lub hauv paus yog ua los ntawm cov pob zeb muaj zog, uas yog mounted rau ntawm lub hauv ncoo pob zeb crushed. Hauv kev tsim, cov kav dej nkag mus rau hauv lub tais, uas yog qhov tseem ceeb ntawm kev siv tshuab. Nws yog qhov tsim nyog rau kev txav ntawm cov dej khib nyiab. Nws tag nrho qhov siab yuav tsum tsis txhob tsawg tshaj li txoj kab uas hla ntawm cov yeeb nkab loj. Nws yog ua los ntawm monolithic pob zeb siv templates. Cov txee yog mounted rau ntawm ob sab ntawm lub tais, ntawm qhov chaw ua haujlwm. Cov ntsiab lus no yuav tsum muaj qhov nqes me ntsis ntawm lub tais.

Dab tsi ntxiv koj yuav tsum paub txog tus qauv tsim ntawm lub manhole

Saib xyuasCov kav dej phwj tuaj tau nruab nrog cov ntaiv thiab cov hlua khi rau qhovntsej thiaj tsis mob. Thiab lawv qhov siab feem ntau yog sib npaug li 1800 millimeters, txoj kab uas hla yuav tsum sib haum mus rau txoj kab uas hla ntawm cov yeeb nkab. Lub caj dab, raws li txoj cai, muaj tus qauv loj, uas yog 700 millimeters. Lub manhole hatch yuav tsum nyob ntawm qhov siab ntawm 70 mus rau 200 millimeters saum av. Cov khoom no plays lub luag haujlwm ntawm kev tiv thaiv lub koob yees duab los ntawm clogging. Nws tiv thaiv tib neeg los ntawm kev sib tsoo. Raws li cov khoom siv rau lub hatch, cam khwb cia hlau tuaj yeem siv tau, nrog rau cov ntaub ntawv polymeric, qhov kawg ntawm qhov txawv ntawm lub zog, durability thiab lightness. Cam khwb cia hlau hatches, txawm tias loj dua, yog qhov tseem ceeb rau kev tso rau ntawm txoj kev, qhov chaw lawv yuav raug hnyav.

Manhole yam ntxwv

Yav dhau los, qhov dej tau ua los ntawm cov pob zeb thiab cib, tab sis niaj hnub no cov qhov dej yas tau siv ntau zuj zus, uas muaj cov khoom zoo ntawm kev nruj. Nyob rau sab hnub poob, cov tshuab no tau siv sijhawm ntev heev. Frost tsis kam ntawm cov khoom siv no tsis ntxiv qhov nrov rau cov khoom lag luam hauv tebchaws Russia rau qee lub sijhawm, tab sis niaj hnub plastics niaj hnub no haum rau huab cua hnyav tshaj plaws. Cov qauv tsim los ntawm cov yas tsis txawv ntawm cov pob zeb uas muaj zog hauv yuav luag txhua yam. Cov qauv muaj lub hauv paus, lub hau npog telescopic thiab cov yeeb nkab ncej. Manhole rings muaj qee zaum tam sim no, nrog rau lub manhole thiab slab. Cov tshuab yas muaj ntau yam zoo dua li cov cuab yeej siv dag zog, vim tias lawv muaj qhov tso tawm hauv lawv lub hauv paus uas tau hloov kho rau qhov ntev.cov kav dej phwj tuaj. Yog tias peb tab tom tham txog cov cuab yeej siv dag zog, ces lawv xav tau kev hloov pauv hauv qhov rau cov kav dej thiab lawv cov tsim, uas suav nrog cov nqi sijhawm thiab nyiaj txiag.

Txawm tias qhov tseeb tias qhov dej yas zoo li tsis yooj yim, kev ntseeg tau tuaj yeem paub qhov txawv ntawm lawv cov yam ntxwv, vim tias cov khoom zoo li no muaj peev xwm ua rau muaj kev kub ntxhov. Yog tias, xav txog ib qho ntawm cov kav dej phwj tuaj, koj pom cov cim 3634 99 - cov manholes ntawm cov manholes nyob rau pem hauv ntej ntawm koj. Tej zaum lawv yuav muaj cua daj cua dub tshwj xeeb hauv dej, txhua tus ntawm nws tus kheej hauv chav kawm. Cov chav kawm hauv qab no feem ntau yog: chav kawm B, uas muaj peev xwm ua haujlwm ntev txog 12.5 tons, thiab chav kawm D, nws tuaj yeem tiv taus txog li 40 tons ntawm lub sijhawm ua haujlwm.

yam ntxwv ntawm cov kua dej yas manholes

Kev tshuaj xyuas dej zoo ua los ntawm cov yas tsis ntev los no tau nce zuj zus los ntawm cov neeg siv khoom. Qhov no yog vim qhov tseeb tias nws tuaj yeem siv rau ntawm qhov dav dav ntawm qhov kub ntawm -25 txog +45 degrees. Sab hauv ntawm cov yeeb nkab yog du kom yooj yim ntxuav. Cov dej ntws tawm yog siv los txuas cov kav dej thiab tom qab ntawd sau cov dej ntws tawm. Qhov siab ntawm tus pas nrig kav thiab cov naj npawb ntawm qhov chaw tawm tuaj yeem xaiv tus kheej los ntawm cov neeg siv khoom, txhua yam yuav nyob ntawm qhov chaw. Cov qauv zoo li no tau npaj ua haujlwm rau ntau tshaj 50 xyoo, thiab lawv tau ua raws li cov kav dej polypropylene. Manhole kav muaj qhov hluav taws xob txoj kab uas hla ntawm 63 txog 200millimeters, thaum txoj kab uas hla ntawm tus pas nrig yeeb nkab yog tus qauv thiab yog 315 millimeters.

Kev ncua deb ntawm cov kab hluav taws xob

Qhov kev ncua deb ntawm cov kab hluav taws xob yuav nyob ntawm txoj kab uas hla ntawm cov yeeb nkab. Yog li, yog tias txoj kab uas hla yog 50 millimeters, ces qhov kev ncua deb yog 35 millimeters. Yog tias txoj kab uas hla ntau dua 2000 millimeters, cov kauj ruam ntawm cov qhov dej yuav tsum yog 300 meters. Nrog tus nqi nruab nrab ntawm 700 txog 900 millimeters, cov qhov dej yuav tsum tau muab tshem tawm ntawm ib leeg los ntawm qhov deb ntawm 100 millimeters.

Qhov tob ntawm cov kav dej manhole

Kev txhim kho cov kav dej phwj yuav tsum ua kom tiav nrog kev teeb tsa cov kav dej. Qhov tob ntawm lawv cov nteg tuaj yeem sib txawv ntawm 30 mus rau 40 centimeters, tab sis nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account qhov nqes hav ntawm cov yeeb nkab hauv av, nws yuav tsum yog ib centimeter ib meter ntawm txoj kev. Koj yuav tsum tsis txhob nqa mus nrog txoj kab nqes ib qho, txij li qhov nkag mus rau hauv qhov dej yuav tsum siab dua, uas yuav ua rau qhov tsawg kawg nkaus poob ntawm ntim. Tsis txhob hnov qab txog cov dej tsis zoo ntawm cov kav dej phwj tuaj. Thaum khawb ib lub trench, koj yuav tsum tsis txhob khawb tob, txawm tias koj npaj yuav ntxiv lub ntiaj teb hauv qab cov yeeb nkab. Nws yog qhov zoo tshaj plaws kom tawm ntawm cov npoo me me, vim tias cov av sprinkled tuaj yeem sag dhau sijhawm, uas yuav ua rau txoj kab nqes ntawm txoj kev poob. Txwv tsis pub muab cov khoom tso rau hauv qab, vim lawv tuaj yeem ua rau cov yeeb nkab puas.

Zaj lus

Tsis txhob tso tsegkev yuav khoom ntawm cov khoom yas hauv kev pom zoo ntawm cov pob zeb ua ntej ua ntej npaj manholes, txij li lawv yog nruj nruj, tuaj yeem nteg tau yooj yim piv rau cov khoom hnyav, thiab kuj muaj tus nqi qis. Thaum lub sij hawm installation, kev siv cov cuab yeej tshwj xeeb tsis tas yuav tsum tau, nrog rau thaum lub sij hawm thauj khoom thiab tshem tawm, koj tuaj yeem nqa cov haujlwm no yam tsis muaj kev pab sab nraud. Cov ntsiab lus zoo li no yooj yim rau kev khiav lag luam, vim lawv tsis tas yuav tsum tau ntxuav tas li. Environmentally friendly cov ntaub ntawv yog siv nyob rau hauv tus txheej txheem ntawm lawv manufacture.
