Koj hnov ​​kev tsim kho ntsuab, thiab lub siab dhia mus rau lub hnub ci vaj huam sib luag, cov hlau siv dua tshiab, lossis cov xim qis-VOC. Tsis tshua muaj kev sib tham pib ntawm lub hauv paus, tshwj xeeb nrog ib yam dab tsi zoo li rudimentary li cov Kev Sib Tw Trapezoidal. Qhov ntawd yog thawj qhov kev xav tsis zoo. Hauv kev xyaum, kev xaiv ntawm lub hauv paus hom tsis yog hais txog kev thauj khoom xwb; nws yog thawj cov khoom tseem ceeb thiab kev txiav txim siab lub zog ntawm qhov chaw, teeb tsa lub suab rau tag nrho qhov project cov peev txheej hneev taw. Kuv tau pom ntau yam specs default mus rau qhov loj loj sib kis footing vim nws yog tus qauv, nchuav ntau pua cubic yards ntawm cov pob zeb ntxiv uas tsis muaj leej twg tau nug. Lub trapezoid, thaum siv judiciously, txiav los ntawm cov pov tseg - lus thiab figuratively.

Ntau dua ib qho duab: Geometry ntawm Efficiency

Lub hauv paus ntsiab lus yog ncaj qha: lub trapezoidal cross-section zoo dua tsom iav qhov kev sib kis ntawm cov khoom thauj los ntawm ib kem lossis phab ntsa mus rau hauv av. Ib daim duab plaub muaj ntau cov pob zeb tuag hauv nws cov ces kaum uas tsis ua haujlwm zoo. Los ntawm txoj kab nqes ntawm sab, koj txo qhov ntim ntawm cov pob zeb xav tau ntau heev rau tib lub peev xwm thauj khoom. Peb tab tom tham txog 15% mus rau 30% tsawg pob zeb, nyob ntawm cov av bearing siab thiab kem load. Qhov ntawd tsis yog qhov tsis tseem ceeb. Txhua qhov cubic mev ntawm cov pob zeb tsis nchuav yog kwv yees li 400 kg ntawm CO2 tsis tso tawm los ntawm cov cement ntau lawm, ntxiv rau tag nrho cov dej sib txuas, kev sib sau ua ke, thiab kev thauj mus los.

Tab sis nws tsis yog rab phom khawv koob. Kev ua tau zoo hinges rau cov ntaub ntawv qhia txog av. Yog hais tias koj tau txais qhov tso cai bearing siab tsis ncaj ncees lawm, tag nrho optimization backfires. Kuv nco qab txog qhov project warehouse qhov twg peb tsim ib tug zoo huv si, sloped footing system raws li kev xeem ua ntej. Tom qab ntawd, kev soj ntsuam ntxaws ntxiv tau nthuav tawm lub hnab ntim muag. Peb yuav tsum rov qab mus rau qhov dav dua, nplawm lub ncoo hauv ntu ntawd, uas zoo li ib kauj ruam rov qab. Nws yog ib zaj lus qhia: tus qauv tsim ntsuab tshaj plaws yog ib qho uas muaj zog thiab ua raws li cov ntaub ntawv muaj tseeb, tsis yog qhov kev xav zoo xwb.

Txoj kev ua haujlwm rau lub trapezoid yog me ntsis nyuaj dua rau txoj kev ncaj nraim. Nws yuav tsum muaj cov kws txawj ntoo lossis cov txheej txheem ua haujlwm tshwj xeeb. Qee zaum, tus nqi ua haujlwm thiab cov khoom siv formwork tuaj yeem cuam tshuam cov kev txuag nyiaj, tshwj xeeb tshaj yog rau cov haujlwm me me. Qhov ntawd yog qhov kev sib tw ua lag luam. Koj yuav tsum khiav cov lej rau tag nrho cov kev cuam tshuam hauv lub neej, tsis yog cov nqi khoom siv xwb. Ntawm qhov loj dua, rov qab footings, zoo li rau kab kab sib chaws hauv lub tsev lag luam, cov formwork tuaj yeem rov qab siv tau ntau, ua rau lub trapezoid yog tus yeej.

Material Synergies thiab Supply Chain Realities

Txo qhov ntim pob zeb ua lwm yam: nws txo qhov kev thov rau kev txhawb nqa. Lub pob zeb me me txhais tau hais tias muaj kev ntxhov siab hauv sab hauv thiab feem ntau tso cai rau qhov yooj yim rebar layout. Qhov no yog qhov chaw muab khoom tuaj. Siv lub zog siab, tsim tau zoo rebar tuaj yeem ua kom zoo dua qhov tsim. Piv txwv li, tus neeg muag khoom zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd. (https://www.zitaifasteners.com), raws li nyob rau hauv Tuam Tshoj tus qauv loj ib feem ntau lawm puag, muab qhov zoo ib yam ntawm fasteners thiab lwm yam Cheebtsam uas ua kom muaj zog tawb tuav lawv cov qauv tsim thaum lub sij hawm ua vaj tse. Qhov kev cia siab ntawd yog qhov tseem ceeb thaum ua haujlwm nrog ntau cov formwork geometry.

Kev thauj mus los yog ib qho loj, feem ntau saib tsis taus ib feem ntawm lub hauv paus ntawm cov pa roj carbon hneev taw. Qhov chaw ntawm koj cov neeg muab khoom siv tseem ceeb. Handan Zitai qhov sib thooj rau txoj kev tsheb ciav hlau loj thiab txoj kev sib txuas (xws li Beijing-Guangzhou Railway thiab National Highway 107) tsis yog qhov chaw muag khoom xwb; nws txhais ua qis embodied zog rau lub bolts thiab accessories uas yuav siv tau nyob rau hauv formwork systems los yog anchorages. Thaum koj tab tom sim txo qis tag nrho cov ntaub ntawv profile ntawm lub hauv paus, txhua qhov txuas hauv cov saw hlau suav. Kev xa khoom los ntawm lub chaw tsim khoom nrog cov khoom siv logistical txhawb nqa lub hom phiaj dav dav.

Txawm li cas los xij, muaj kev ceev faj. Green Source tsis yog nyob ntawm qhov deb xwb. Nws yog hais txog kev tsim khoom ua ntej. Puas yog steel zeb siv hluav taws xob arc rauv nrog cov khoom siv rov ua dua tshiab? Qhov ntawd yog ib lo lus nug peb tab tom pib nug ntxiv, thawb lub hom phiaj ntsuab txhua txoj kev rov qab mus rau cov khoom siv raw. Lub trapezoidal footing ua nrog nkauj xwb, thee-fired steel rebar tseem muaj qhov hnyav hneev taw, txawm tias nws siv cov pob zeb tsawg.

On-Site Nuances thiab Kev Tswj Dej

Cia peb nkag mus rau hauv av. Trapezoidal footing, nrog nws txoj kab nqes, tuaj yeem cuam tshuam sib txawv nrog cov av thiab dej. Thaum lub sij hawm excavation, lub sloped profile tej zaum yuav ruaj khov nyob rau hauv tej yam av ntau tshaj ib tug ntsug-sided qhov, txo shoring xav tau kev pab. Tab sis nyob rau hauv cov huab cua ntub heev, qhov loj ntawm qhov chaw ntawm daim ntawv sloped tuaj yeem ua rau muaj kev yaig lossis dej ntog ua ntej lub ncuav. Koj xav tau kev tswj xyuas qhov chaw zoo - qhov chaw nrawm ntawm cov pob zeb ntshiv lossis cov ntaub thaiv npog.

Ib zaug kuv tau ua haujlwm ntawm ib qhov project ze ntawm lub rooj dej siab. Lub trapezoidal tsim, los ntawm kev tsim txiaj ntawm qhov ntiav ntiav rau tib qhov kev coj tus kheej (lossis muaj lub hauv paus dav dua rau kev ruaj ntseg), tau pab peb khaws lub hauv paus ncoo saum lub rooj dej hauv qee qhov chaw, zam cov nqi thiab lub zog siv cov txheej txheem sib sib zog nqus dewatering. Qhov ntawd yog qhov yeej npaj txhij txog. Nws hloov qhov kev xaiv ntawm cov qauv mus rau qhov zoo dua hydrological.

Conversely, qhov ua tiav ntawm qhov chaw sloped yog trickier. Yog tias koj tab tom npaj rau lub hauv paus uas tej zaum yuav raug cuam tshuam rau kev tsim vaj tsev (hauv qee qhov kev tsim ntsuab niaj hnub), tau txais kev sib tw, kev ncaj ncees-ntsej muag pob zeb ua tiav ntawm txoj kab nqes yuav tsum tau zoo heev formwork thiab pouring txheej txheem. Ib txoj hauj lwm botched ntawm no txhais tau tias kev kho ntau dua, ntau cov ntaub ntawv rau patching-negating thawj zaug txuag nyiaj. Nws xav tau tus qauv siab dua ntawm cov khoom siv tes ua.

Lub Neej Txoj Kev Pom Zoo thiab Deconstruction

Kev tsim kho ntsuab yog txav mus dhau qhov kev tsim kho theem ua tau zoo. Peb tab tom pib xav txog qhov kawg ntawm lub neej. Trapezoidal footing, frankly, yog ib yam nkaus li ib yam li lwm yam pob zeb hauv paus. Nws tsis yog tsim los rau kev tshem tawm yooj yim. Txawm li cas los xij, nws cov khoom siv tau zoo txhais tau tias tsis muaj kev sib koom ua ke nrog yog tias cov qauv raug rhuav tshem ib hnub thiab qhov chaw kho. Tsawg loj kom tawg, tsawg rubble kom rub tawm, thiab muaj peev xwm ntau dua rau kev ntxuav rov qab.

Qhov no txuas rau kev tsim kho kom haum. Ib qho yooj yim, optimized foundation yuav tso cai rau yav tom ntej ntsug expansion nrog tsawg kev txhawj xeeb txog overloading tus thawj footings. Peb tsim ib lub koom haum zej zog nrog rau qhov no hauv siab. Cov ntaub qhwv trapezoidal tau loj nrog lub mezzanine yav tom ntej hauv siab. Cov neeg tau txais kev cawmdim ntawm qhov pib ua vaj tse, thiab lub tsev muaj txoj hauv kev loj hlob yam tsis xav tau kev cuam tshuam lub hauv paus ntxiv dag zog tom qab. Qhov ntawd yog lub tswv yim ntsuab mus sij hawm ntev.

Tab sis cia peb ua tiag: feem ntau cov footings tau faus thiab tsis nco qab lawm. Qhov tiag tiag lifecycle yeej yog nyob rau hauv lub upfront peev nyiaj txuag. Lub luag haujlwm ntawm trapezoid feem ntau yog txo qis cov pa roj carbon monoxide thawj zaug thiab kev cuam tshuam ecological cuam tshuam los ntawm cov khoom siv rho tawm. Nws daim ntawv pov thawj ntsuab tau txais yuav luag tag nrho thaum thawj ob peb lub lis piam ntawm qhov project, kaw rau hauv lub neej ntawm lub tsev.

Tshaj Qhov Zoo Tshaj Plaws: Thaum Nws Tsis Ua Haujlwm

Nws yuav tsis muaj lub luag haujlwm los pleev xim qhov no raws li kev daws teeb meem thoob ntiaj teb. Rau cov khoom siv me me (cov tsev me me, cov tsev), cov khoom siv ruaj khov yog qhov tsawg, thiab qhov ntxiv formwork complex tsis tsim nyog. Txoj cai ntawm kev txo qis rov qab siv tau. Tsis tas li ntawd, nyob rau hauv cov cheeb tsam seismic, cov qauv tsim ua ntej hloov pauv mus rau ductility thiab lub zog dissipation. Lub footing zoo ua subordinate rau qhov yuav tsum tau ntawm seismic khi-beams thiab shear phab ntsa. Lub trapezoid tseem tuaj yeem haum, tab sis nws tsis yog kev txhawj xeeb tsav tsheb.

Kuv tau koom nrog hauv qhov kev rov tsim dua uas peb xav tau los txhawb nqa cov qauv uas twb muaj lawm. Sim tsim cov duab trapezoidal hauv nruj, cov hauv qab daus uas twb muaj lawm yog npau suav phem. Peb siv cov ntaub qhwv lub ntsej muag rau kev yooj yim thiab ceev. Qhov kev xaiv ntsuab tshaj plaws yog qee zaum ib qho uas txo qis qhov chaw cuam tshuam thiab lub sijhawm tsim kho, txo lub zog tag nrho thiab kev sib raug zoo ntawm kev tsim. Dogma tsis muaj qhov chaw nyob ntawm qhov chaw nyob.

Yog li, qhov kev txiav txim yog dab tsi? Cov Kev Sib Tw Trapezoidal yog ib tug muaj zog, underutilized cuab tam nyob rau hauv ntsuab siv cov cuab yeej. Nws lub luag haujlwm tsis yog glamorous, tab sis nws yog cov khoom siv tseem ceeb. Nws yuam kom muaj kev xav ntau ntxiv nrog rau thawj lub tsev peb tso. Nws hais kom peb nug txog lub neej ntawd, kom muaj nuj nqis engineering precision, thiab xav txog cov saw hlau uas txhawb nqa nws. Nws yuav tsis daws txhua yam, tab sis nyob rau hauv cov ntsiab lus tseem ceeb - nrog cov av zoo, kev npaj ua haujlwm ntse, thiab kev pom zoo ntawm cov khoom siv - nws yog ib qho yooj yim mus rau kev tsim ntau dua nrog tsawg dua. Thiab qhov ntawd, ntawm nws qhov tseem ceeb, yog qhov kev tsim kho ntsuab yuav tsum yog li cas.
