Lub qhov dej tuaj yeem nruab tau thaum tso ntau yam kev sib txuas lus - cov kav dej, cov kav dej, cov kab hluav taws xob, thiab lwm yam. Tab sis feem ntau, lawv cov phab ntsa tau ntxiv dag zog nrog cov nplhaib npaj tshwj xeeb. Cov khoom ntawm ntau yam no yuav muaj qhov sib txawv, txoj kab uas hla thiab qhov siab.
ntau yam tseem ceeb
Thaum tso kev sib txuas lus, lub nplhaib zoo tuaj yeem siv tau:
- Phab ntsa. Cov khoom zoo li no yog siv los tsim lub caj dab ntawm ntau yam qauv zoo.
- qauv. Rings ntawm hom no yog siv los ntxiv dag zog rau phab ntsa ntawm lub qhov dej rau kev sib txuas, cov kav dej, cov kav dej, thiab lwm yam.
- Pab txhawb nqa. Cov nplhaib zoo li no yog tsim los txiav txim thiab sib txawv ntawm qhov tsis zoo thiab cov qauv tsim.
Cov nplhaib zoo tuaj yeem ua los ntawm cov pob zeb ua pob zeb lossis yas. Ob qho tib si siv ntau zaus thaum tso kev sib txuas lus, thiab tuaj yeem muaj qhov zoo thiab qhov tsis zoo.
Yuav ua li cas yog cov pob zeb muaj zog
Cov khoom ntawm no ntau yamyog tsim los ntawm cov cement mortar thiab hlau fittings. Pob zeb rings yog poured rau hauv pwm ntawm ib tug tshwj xeeb tsim.
Yuav kom lub nplhaib kom muaj zog li sai tau, vibrocompression technology yog siv rau hauv lawv cov khoom. Qee qhov tsis zoo ntawm cov khoom ntawm hom no yog qhov hnyav heev. Cov khoom siv pob zeb ua kom muaj zog yog ntsia rau hauv qhov pits, feem ntau yog siv cov cuab yeej tshwj xeeb. Qhov hnyav ntawm lub nplhaib zoo nrog ib txoj kab uas hla ntawm 1000 hli, phab ntsa tuab ntawm 80 hli, qhov siab ntawm 890 m ua los ntawm cov pob zeb qib 200, piv txwv li, yog 0.6 tons.
Yuav ua li cas yog hom pob zeb muaj zog
Thaum npaj cov qhov dej rau ntau lub hom phiaj, lawv tuaj yeem siv tau:
- Ntxhais zoo nkauj. Cov khoom ntawm hom no tuaj yeem siab lossis qis. Rings ntawm hom no kuj txawv ntawm phab ntsa thickness.
-
Zoo hauv qab ntiv nplhaib. Cov khoom no yog tsim los ntawm high-strength qhob qib M200-M500. Rings ntawm hom no yog cov qauv monolithic thiab yog siv los muab cov tso tsheb hlau luam kaw.
- Nplhaib nrog lub xauv. Cov nplhaib zoo li no muaj qhov tshwj xeeb notches nyob rau hauv qab thiab nyob rau sab saum toj raws cov npoo. Cov khoom ntawm hom no yog siv thaum sib dhos zoo shafts, piv txwv li, ntawm cov av tsis ruaj khov.
Cov pob zeb ua pob zeb zoo yog puag ncig lossis square hauv cov duab. Thaum tso kev sib txuas lus, thawj hom khoom siv feem ntau yog siv.
kos npe ntawm cov pob zeb pob zeb
Yuav kom cov neeg siv khoom nkag siab txog lub hom phiajlub hom phiaj ntawm lub nplhaib, manufacturers cim lawv nyob rau hauv ib tug tshwj xeeb txoj kev. Qhov zoo tshaj plaws hauv cov ntawv tsim kho rau cov khoom ntawm hom no yog:
- KO - txhawb pob zeb txhawb nqa lub nplhaib ntsia hauv qab - hauv lub hauv paus ntawm kuv;
- KS - phab ntsa rings;
- KVG - cov khoom siv hauv kev npaj dej lossis roj qhov dej;
- KLK - rings siv hauv cov kav dej nag;
-
KFK - cov khoom siv hauv kev teeb tsa cov kav dej lossis cov khoom sib txuas.
Ntxiv rau cov ntawv, cov cim ntawm cov pob zeb ua vaj tse feem ntau muaj cov lej qhia lawv txoj kab thiab qhov siab. Cov npog thiab hauv qab ntawm cov khoom no tuaj yeem raug cim raws li cov ntawv PP lossis PK thiab PN thiab PD.
qauv qhov ntau thiab tsawg ntawm cov pob zeb pob zeb
Thaum npaj txhua yam kev sib txuas lus, cov khoom siv ntawm hom no muaj ntau qhov ntau thiab tsawg. Tab sis feem ntau, cov phab ntsa ntawm lub qhov dej yog ntxiv nrog cov nplhaib zoo:
- KS10-9 890 mm siab thiab 1 m inch;
- KS10-6, uas nws qhov ntev yog 590 thiab 1000 hli feem;
- KS10-3 250 mm siab thiab 1 m inch.
Cov phab ntsa tuab ntawm cov pob zeb ua kom muaj zog siv hauv kev sib txuas lus tuaj yeem sib txawv ntawm 70-120 hli. Feem ntau, cov khoom uas muaj txoj kab uas hla ntawm 1 m yog ntsia rau hauv qhov dej, tab sis thaum txhim kho engineering systems, rings ntawm lwm qhov ntau thiab tsawg tuaj yeem siv - los ntawm70 mus rau 200 cm. Qhov siab ntawm cov khoom xws li 10-100 cm.
yam ntxwv ntawm cov khoom siv ntxiv dag zog
Cov dej khib nyiab feem ntau yog ua los ntawm cov cement mortar siv cov xuab zeb sib tov sib xyaw. Tseeb tiag, thaum lub sijhawm ua haujlwm, cov khoom no feem ntau nkag mus rau hauv dej.
In the manufacturing of reinforced concrete rings, enterprises use not dog dig formwork, but special vibroforms. Ib tug reinforcing qauv yog xub ntsia rau hauv lawv. Cov pob zeb sib tov yog muab tso rau hauv pwm thiab compacted los ntawm kev vibration. Cov thev naus laus zis no ua rau nws tuaj yeem tsim cov nplhaib ruaj khov tshaj plaws.
Dab tsi yog qhov dej yas
Cov khoom ntawm hom no, tau kawg, me ntsis qis dua rau cov pob zeb ntxiv. Txawm li cas los xij, xws li cov nplhaib muaj ib qho txiaj ntsig tseem ceeb. Cov qhov dej yas yog yooj yim dua rau nruab dua li cov pob zeb uas muaj zog. Koj tuaj yeem txhim kho cov khoom zoo li no hauv qhov chaw yam tsis tas siv cov cuab yeej tshwj xeeb, tsuas yog los ntawm tes.
Qhov dej ntawm hom no yog ua los ntawm cov ntaub ntawv polymeric thiab tuaj yeem muaj ob phab ntsa du thiab corrugated. Nyob ntawm txoj kab uas hla, cov khoom ntawm hom no tau muab faib ua nqaim (txog 1 m) thiab dav (dhau 1 m).
Yam khoom yas zoo rings
Los ntawm kev tsim, cov khoom ntawm ntau yam no tau muab faib ua monolithic thiab prefabricated. Cov hom tom kawg ntawm qhov dej yog kim dua, tab sis kuj pom tau tias siv tau yooj yim dua. Yog tias xav tau, lub qhov dej zoo li no tuaj yeem hloov kho rau lub qhov tob ntawm txhua qhov tob.
Los ntawm lub hom phiaj, cov khoom zoo li no tuaj yeem yog:
- sej;
- tap;
- kho dej.
Cov kav dej yas lim dej, tig, yog:
- kho nrog lub tais;
- sedimentary, ntxiv los ntawm cov kav dej;
- poob;
- tshuaj ntsuam kaw nrog ntaiv;
- eccentric.
Tsis tas li ntawd, thaum tso kev sib txuas lus, cov kav dej kaw tau siv tau. Cov khoom zoo li no muaj hauv qab thiab npog nrog lub hau.
Ntau yam raws li cov khoom siv ntawm kev tsim khoom
Nyob rau hauv no hais txog, cov yas lim dej yog qhov txawv:
- polyethylene nrog lub neej ua haujlwm ntev;
- ruaj khov polypropylene;
- corrosion-resistant fiberglass.
Kev tsim ntawm txhua hom nplhaib no yog qhov kev teeb tsa ntawm qhov chaw siv sijhawm tsawg kawg nkaus. Tag nrho cov seams thiab pob qij txha ntawm cov khoom yas yog xav ua ntej.
Qhov ntev thiab yam ntxwv ntawm lub qhov dej yas
Cov khoom ntawm ntau yam no, tau kawg, kuj txawv ntawm cov duab thiab qhov loj me. Cov nplhaib zoo ua los ntawm cov yas tuaj yeem muaj txoj kab uas hla ntawm 600 mus rau 1500 hli. Phab ntsa thickness ntawm cov khoom ntawm hom no feem ntau yog 50 hli. Tab sis kuj tseem muaj cov kev xaiv tsis zoo rau cov nplhaib nrog cov phab ntsa tuab lossis nyias.
siabyas rings pib los ntawm 500 mm. Ntawm qhov dej siab tshaj plaws, daim duab no yog 1500 mm. Sab nraud, cov nplhaib yas feem ntau yog ntxiv nrog stiffeners, uas ua rau kom lub neej ua haujlwm tau zoo. Txawm hais tias qhov tseeb tias lub qhov dej yas ntawm cov khoom siv pob zeb muaj zog tsis zoo, feem ntau lawv muaj peev xwm tiv taus av tsis muaj teeb meem ntau.
