Chav Kawm D400, ua raws li cov qauv tsim nyog, nrog kev ntsuas ntsuas ntawm 400kN (kwv yees li 40 tons). Nws tuaj yeem tiv taus lub sijhawm ntev - lub sijhawm dhau ntawm cov tsheb hnyav 20-30 tons, ua kom pom kev tiv thaiv zoo tshaj -slip kev ua haujlwm thiab ua tau raws li qhov yuav tsum tau siv rau hauv cov haujlwm hnyav.
II. Cov yam ntxwv ntawm cov khoom
Lub hau npog no yog ua kom zoo rau qhov hnyav - lub luag haujlwm hauv nroog thiab qhib - huab cua ib puag ncig, ntsuas lub zog, kav ntev, thiab kev nyab xeeb, thiab ua raws li cov qauv kev lag luam.
(I) Siab -Cov khoom siv zog, ruaj khov
Cov khoom siv tseem ceeb yog cov hlau nplaum (QT500-7 lossis QT600-}3), nrog tus nqi spheroidization Ntau dua lossis sib npaug li 80%, cuam tshuam-resistant, corrosion-resistant, thiab kev pab cuam lub neej tshaj 15 xyoo. Rau cov xwm txheej tshwj xeeb, steel fiber reinforced pob zeb tuaj yeem xaiv tau, tsim nyog rau cov cheeb tsam txias sab qaum teb, nrog lub neej ua haujlwm tshaj 30 xyoo. Accessories yog ua los ntawm stainless hlau los txhim kho durability.
(II) Scientific Structural Design, ruaj khov thiab puas tsuaj -Cov pov thawj
Tus qauv tsim suav nrog cov ces kaum loj, txhawb nqa tav, thiab peb - taw tes ncua kev txhawb nqa kom ua tiav txawm tias thauj khoom faib thiab ua haujlwm ntsiag to. Ua ntej-drilled qhov thiab textured kev kho mob ntawm lub manhole puag txhim khu kev ruaj ntseg installation, thiab lub kaum sab xis positioning tsim txhim kho kev tsim kho efficiency.
(III) Kev tiv thaiv kev nyab xeeb, Kev txhawj xeeb -Dawb lav
Nruab nrog ntau txheej tiv thaiv nrog rau kev nyab xeeb keyways, tiv thaiv- tub sab nyiag, tiv thaiv- plam, thiab tiv thaiv- ntog nta. Qee cov qauv tuaj yeem nruab nrog kev paub txog kev ua haujlwm, ua kom muaj kev nyab xeeb los ntawm ntau yam xws li kev ua haujlwm, kev ua haujlwm, thiab kev tiv thaiv khoom vaj khoom tsev.
(IV) Muaj zog Adaptability, Ua raws li cov qauv
Ua raws li cov qauv tsim nyog hauv tsev thiab thoob ntiaj teb, nws tau sib haum nrog ntau yam kev tshuaj xyuas hauv nroog xws li cov kav dej, dej, thiab hluav taws xob. Nws tuaj yeem txais kev tsim qauv tsim kom sib xyaw nrog txoj kev nto, thiab cov ntaub ntawv tseem ceeb raug cim rau saum npoo kom yooj yim txij nkawm.
III. Siv tau Scenarios
Nrog rau 400kN load-cov kabmob muaj peev xwm thiab loj 900mm txoj kab uas hla, nws yog siv rau hauv:
Txoj kev hauv nroog loj thiab theem nrab, txoj kev nthuav dav, thiab txoj kev nyob deb nroog (tshwj xeeb yog thaj chaw uas muaj kev sib koom ua ke);
01
Hnyav- txoj kev thauj khoom xws li txoj kev loj thiab thawj- txoj kev hauv chav kawm;
02
Hnyav- chaw thau khoom xws li chaw nres tsheb loj, chaw nres tsheb thauj khoom, thiab chaw nres tsheb thauj khoom;
03
Cov cheeb tsam uas xav tau kev saib xyuas loj - txoj kab uas hla, xws li nyob ib ncig ntawm cov chaw nres tsheb roj thiab cov twj tso kua mis, thiab cov dej nag loj thiab cov kav dej phwj tuaj;
04
Lwm thaj chaw hauv nroog uas xav tau siab rau kev thauj khoom -cov kabmob muaj peev xwm thiab qhov loj me.
05
IV. Installation thiab Maintenance Points
Kev txhim kho kom raug thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb rau kev ua kom muaj kev pabcuam lub neej thiab kev nyab xeeb ntawm kev tsheb.
Yuav tsum tau nruab
Ntxuav lub manhole qhib, ncuav C30 pob zeb rau lub hauv paus thiab kho yam tsawg kawg 7 hnub;
Nruab lub manhole puag horizontally, ua raws li lub manhole qhib thiab txoj kev nto elevation (yuam kev tsawg dua los yog sib npaug zos rau 2 hli);
Sau lub manhole puag nrog mortar tag nrho, siv lub qhov nyob rau hauv lub manhole puag los txhim khu kev twb kev txuas stability;
Tom qab kev teeb tsa, ua cov kev hloov kho kom nruj kom haum, qhib du, thiab tso cov khoom tiv thaiv kom raug.
Cov Ntsiab Lus Kho
1
Ua kev soj ntsuam tsis tu ncua; hloov tam sim ntawd yog tias puas, tawg, lossis kho ntau tshaj 3 hli;
2
Ntxuav cov khib nyiab thiab cov xuab zeb kom ntseeg tau tias kev ua haujlwm tsis zoo thiab cov dej tsis muaj kev cuam tshuam;
3
Tshawb xyuas cov khoom siv; kho lossis hloov tam sim yog xeb lossis puas;
4
Nyob rau hauv ib puag ncig corrosive, ua tsis tu ncua los tiv thaiv- kev kho corrosion thiab tsis tu ncua kuaj load-cov kabmob muaj peev xwm.
