waterstop steel phaj

Thaum cov neeg feem coob hnov 'waterstop steel phaj', lawv pom ib lub tiaj tus, inert daim hlau. Qhov ntawd yog thawj qhov yuam kev. Nws tsis yog ib qho kev thaiv xwb; nws yog ib qho dynamic tivthaiv nyob rau hauv ib qho kev sib koom ua ke, thiab nws cov kev ua tau zoo hinges ntawm cov ntsiab lus feem ntau spec ntawv gloss. Qib, qhov chaw tiav, qhov sib npaug ntawm cov galvanizing - cov no tsis yog cov ntsiab lus kawm. Kuv tau pom tej yaam num uas lub phaj ntsib ASTM A36 ntawm daim ntawv tab sis ua tsis tau tejyam nyob rau hauv lub trench vim hais tias tsis muaj leej twg txiav txim siab yuav ua li cas nws nto yuav sib raug zoo nrog cov hydrophilic sealant. Nws yog cov khoob ntawm txoj kev xav thiab ncuav uas txhais tau tias ua haujlwm tiag tiag.

Core Misconception: Material vs. System

Qhov mob taub hau loj tshaj plaws uas kuv ntsib yog qhov kev xav ntawm kev yuav khoom. Cov kws kho tsheb hais txog qhov tuab 6 hli waterstop steel phaj, 300mm dav, thiab xav tias txoj haujlwm tiav. Tab sis lub phaj ntawd tsis muaj txiaj ntsig yam tsis xav txog nws lub luag haujlwm hauv qhov system. Yuav ua li cas yog anched? Puas yog cov bolt qhov punched lossis drilled? Punched qhov tawm me ntsis burr uas tuaj yeem rhuav tshem cov ntaub thaiv npog ib puag ncig thaum lub sijhawm teeb tsa - cov ntsiab lus me me uas ua rau muaj qhov loj. Kuv ib txwm hais kom drilled qhov rau cov ntawv thov tseem ceeb, txawm tias nws raug nqi ntau dua. Nws yog kev sib ntaus nrog kev yuav khoom txhua lub sijhawm, tab sis nws yog kev sib ntaus tsim nyog muaj.

Tom qab ntawd muaj qhov teeb meem ntawm qhov ntev. Peb ib zaug xaj 3-meter ntev ntev rau lub qhov dej ntev. Zoo li muaj txiaj ntsig. Tab sis nyob rau hauv lub teb, splicing cov seem nyob rau hauv ib tug av nkos, kaw trench yog ib tug npau suav phem. Ua kom tiav ib qho txuas ntxiv, watertight weld nyob rau hauv cov xwm txheej no yuav luag tsis yooj yim sua. Peb tau kawm ua haujlwm nrog tus neeg tsim khoom los muab cov kev cai ntev uas haum rau peb cov ncuav qab zib, txo qis cov pob qij txha. Nws xav tau kev sib koom ua ntej ua ntej nrog tus neeg muag khoom zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd., tab sis kev lag luam tawm hauv kev ntseeg tau yog qhov tseem ceeb. Lawv qhov chaw nyob hauv Yongnian, qhov chaw tsim khoom loj, ua tau zoo li no ntawm kev hloov pauv, kev tsim khoom tsim ua tau yam tsis muaj kev siv nyiaj txiag.

Galvanizing yog lwm lub kaus mom worms. Ib txheej zinc txheej hnyav, hais tias 600 g / m2, tsis lav qhov sib xws. Kuv tau txais daim hlau uas cov txheej txheej tau sib sau ua ke ntawm cov npoo tab sis nyias nyias hauv nruab nrab. Nyob rau hauv ib puag ncig alkaline ntawm pob zeb, qhov chaw nyias ua lub anode thiab corrodes aggressively. Tam sim no, kuv ib txwm hais tias galvanizing yuav tsum tau ua tom qab tag nrho cov txiav thiab drilling tiav. Qhov no ua kom cov npoo txiav raug tiv thaiv. Nws zoo nkaus li pom tseeb, tab sis koj yuav xav tsis thoob tias pes tsawg mills sim muab cov khoom ua ntej coated rau fabrication.

Kev Txhim Kho: Qhov Kev Xav Tau Raws Li Av

Koj tuaj yeem muaj lub phaj zoo meej, thiab tseem ua tsis tiav ntawm kev teeb tsa. Txoj cai tseem ceeb: nws yuav tsum tau kho ua ntej lub pob zeb nchuav. Suab yooj yim. Tab sis nyob rau hauv ib tug complex formwork nrog rebar congestion, zoo txhawb ib tug ntev, floppy steel phaj yog ib tug khoom siv tes ua. Yog tias nws tsis nruj, kev co pob zeb yuav txav nws, tsim kom muaj qhov tsis muaj zog. Peb pib siv nplooj siab L-shaped anchoring tuav welded ntawm ib ntus, khi lawv rov qab mus rau lub ntsiab rebar tawb. Nws ntxiv cov khoom tab sis tshem tawm kev txav mus los.

Kev sib koom ua ke nrog lwm cov ntaub ntawv tseem ceeb. Qhov twg waterstop steel phaj ua tau raws li PVC lossis roj hmab waterstop, kev hloov pauv nthuav dav yog txhua yam. Tsuas yog muab lawv ua ke yog thov kom muaj teeb meem. Tam sim no peb siv lub Hoobkas-fab fab kev hloov pauv hloov pauv uas kho cov hlau rau hauv qhov hloov pauv hloov pauv, uas peb mam li lauj kaub rau hauv lub sealant. Nws yog ib qho me me, kim, tab sis nws yog lub pob zeb tseem ceeb ntawm tag nrho cov kev sib koom tes. Kev nrhiav cov khoom siv txhim khu kev qha no yog qhov tseem ceeb, uas yog vim li cas peb feem ntau saib mus rau cov tuam txhab tshwj xeeb hauv kev sib koom ua ke hauv kev lag luam. Lub siab ntawm cov kws tshaj lij thiab kev xa khoom hauv thaj chaw zoo li Yongnian District, nrog nws txoj kev ncaj qha mus rau kev tsheb ciav hlau loj thiab txoj kev sib txuas, txhais tau hais tias cov neeg muag khoom muaj peev xwm muab tau cov kev ua tiav, sib xyaw ua ke ntau dua li cov khoom sib cais xwb.

Kev tshuaj xyuas Weld yog lwm qhov kev sib tw hauv cheeb tsam. Ntawm ib qhov project, peb tau zoo nkauj nruam fillet welds. Dhau kev kuaj pom. Tab sis peb muaj ib tug xau. Qhov teeb meem? Micro-fissures los ntawm vuam sai heev nyob rau hauv huab cua txias. Cov hlau tau ntsib spec, tab sis qhov xwm txheej tsis yog. Tam sim no, rau cov pob qij txha tseem ceeb, peb qhia meej thiab them rau kev kuaj dye-penetrant ntawm ib qho piv txwv ntawm thaj chaw welds. Nws tsis yog tus qauv kev coj ua, tab sis nws ntes cov qhov tsis zoo uas koj tsis pom.

Cov Accessories uas tsis xaiv tau

Bolts thiab txiv ntseej yog ib qho kev xav tom qab kom txog thaum lawv ua tsis tiav. Siv cov qauv carbon steel bolts kom ruaj ntseg galvanized waterstop steel phaj yog ib qho classic galvanic corrosion ntxiab. Peb muab kub-dip galvanized fasteners los ntawm tib batch raws li lub phaj kom paub meej compatibility. Txawm li ntawd los, cov xov yuav tsum tau caum tom qab galvanizing los xyuas kom meej torque. Qhov kev nthuav dav ntawm cov fasteners no yog vim li cas qee zaum peb hla dhau cov neeg xa khoom thiab mus ncaj qha rau cov kws tshaj lij. Ib lub tuam txhab xws li Handan Zitai, nyob rau hauv Tuam Tshoj tus qauv loj tshaj plaws hauv paus, nkag siab cov nuances vim lawv nyob thiab ua pa fastener logistics thiab metallurgy. Lawv qhov sib thooj rau kev nthuav dav thiab kev tsheb ciav hlau tsis yog qhov chaw muag khoom xwb; nws txhais tau hais tias lawv tuaj yeem tswj tau qhov kev xa tawm ntawm cov khoom tshwj xeeb, coated uas lub zeb steel loj yuav tsis thab nrog.

Bentonite panels qab phaj yog lwm qhov nuance. Lawv yog ib tug thaub qab, ib tug swellable cushion. Tab sis yog tias qhov sib txawv ntawm lub phaj thiab lub ntsej muag excavation loj heev, bentonite tuaj yeem nthuav tawm tsis sib xws thiab tsim voids. Peb tam sim no qhia txog qhov sib txawv siab tshaj plaws ntawm 25mm thiab xav tau cov bentonite los nruab rau hauv ib txheej txuas ntxiv, tsis muaj kev sib tsoo. Nws yog kev siv zog los tshuaj xyuas, tab sis nws kaw txoj kev kawg rau dej.

Thaum kawg, muaj kev npaj nto rau sealants. Ib qho ci, tshiab galvanized nto yog txaus ntshai rau adhesion. Peb xav tau lub teeb cheb-blast lossis acid etch ntawm thaj chaw uas yuav siv lub sealant, ua tawm ntawm qhov chaw raws li kev tswj xyuas. Sim npaj qhov chaw nyob rau hauv ib qho chaw ntub dej, qias neeg trench yog qhov lav tsis tau.

Cov lus qhia los ntawm Kev Ua Tsis Taus

Thaum ntxov hauv kuv txoj hauj lwm, peb muaj phab ntsa hauv qab daus ntws tawm ntau heev. Waterstop steel phaj yog rau spec, ntsia seemingly kom raug. Tus neeg ua txhaum? Kev daws teeb meem sib txawv. Lub tsev nyob, tab sis cov phab ntsa sab nraud tsis txav ntau npaum li cas. Lub steel phaj, rigidly embedded nyob rau hauv ob qho tib si, sheared txoj cai ntawm kev tsim kho kev sib koom tes. Nws yog ib qho teeb meem tsim, tsis yog cov khoom siv. Lub phaj ua nws txoj haujlwm zoo heev. Tam sim no, nyob rau hauv cov cheeb tsam uas paub los yog muaj peev xwm sib txawv txav, kuv sib cav tawm tsam ib lub phaj steel. Peb siv lub tshuab hybrid nrog lub nruab nrab-lub teeb roj hmab waterstop uas tuaj yeem ua raws li kev txav mus los, flanked los ntawm cov hlau phaj rau kev tiv thaiv corrosion ntxiv thiab thaub qab. Nws yog qhov nyuaj dua, tab sis nws lees paub qhov tseeb.

Qhov kev ua tsis tiav ntawd tau qhia kuv kom saib saum toj. Tam sim no, kuv nug tus kws kho qhov teeb meem kev sib hais haum ua ntej kuv tseem qhia txog hom waterstop. Nws tau txav kuv lub luag haujlwm los ntawm tsuas yog siv cov specs mus ua ib feem ntawm kev sib tham txog kev pheej hmoo.

Lwm zaj lus qhia me ntsis: lub sijhawm logistics. Peb ib zaug muaj ib pab pawg zoo meej tuaj txog ntawm qhov chaw ob lub lis piam ntxov. Lawv tau khaws cia rau hauv av, tsis muaj kev tiv thaiv. Los ntawm lub sij hawm ncuav, lawv muaj nto xeb thiab paug. Peb yuav tsum tau sandblast lawv nyob rau ntawm qhov chaw, uas ruined lub meej galvanizing. Tam sim no, peb qhov kev yuav khoom suav nrog cov qhov rais xa khoom nruj thiab cov txheej txheem khaws cia ntawm qhov chaw - nce siab ntawm cribbing thiab npog. Qhov no yog qhov chaw muab khoom siv logistical kev ntseeg siab yog qhov tseem ceeb raws li lawv cov metallurgy. Ib lub chaw tsim khoom nyob nrog kev nkag ncaj qha mus rau National Highway 107 thiab Beijing-Shenzhen Expressway, zoo li Zitai, feem ntau tuaj yeem ua haujlwm zoo kom haum rau lub sijhawm tsim kho kom ntseeg tau ntau dua li tus neeg xa khoom nyob deb, txo cov kev pheej hmoo cia.

Kaw lub voj: Nws yog Hais Txog Kev Cia Siab

Yog li, dab tsi yog qhov takeaway? Qhia meej a waterstop steel phaj tsis yog ib qho haujlwm checkbox. Nws yog ib qho kev tawm dag zog hauv kev cia siab tias txhua yam uas tuaj yeem mus tsis ncaj ncees lawm ntawm lub Hoobkas hauv pem teb thiab kev kho zaum kawg ntawm cov pob zeb. Nws yog hais txog kev tswj cov txheej txheem ntawm lub zeb, thaum lub sij hawm fabrication, logistics, thiab thaum lub sij hawm installation. Cov khoom siv yooj yim, tab sis qhov system tsis yog.

Cov txiaj ntsig zoo tshaj plaws los ntawm kev kho cov phaj tsis yog cov khoom lag luam, tab sis raws li cov khoom siv precision. Qhov no txhais tau hais tias koom nrog cov neeg muag khoom uas nkag siab txog tag nrho cov ntsiab lus, tsis yog tus nqi tonnage xwb. Nws txhais tau tias nrhiav cov neeg koom tes hauv thaj chaw tsim khoom sib koom ua ke - qhov chaw uas cov kws tshaj lij fastener, txheej txheej, thiab kev sib koom ua ke sib koom ua ke. Tus nqi tsis yog nyob rau hauv cov hlau xwb; nws yog nyob rau hauv cov ntaub ntawv sau, kev paub txog yuav ua li cas kom cov hlau ua tau zoo nyob rau hauv lub ntiaj teb tiag, tsis zoo tag nrho ntawm qhov chaw tsim kho.

Thaum kawg, kev vam meej yog nyob ntsiag to. Nws yog qhov tsis muaj qhov xau, qhov tsis muaj kev ntshai hu rov qab. Nws yog phab ntsa qhuav hauv qab daus uas tsis muaj leej twg xav txog dua. Thiab qhov ntawd yog qhov kev qhuas siab tshaj plaws rau qhov dej tso dej, nyob rau ntawm qhov chaw zoo, zoo-ntsia hlau phaj, tuaj yeem tau txais.
