Raws li lub ntsiab lus tseem ceeb ntawm spatial txhais thiab kev ruaj ntseg, kev xaiv ntawm cov khoom laj kab cuam tshuam ncaj qha rau kev ua tau zoo, kev ua haujlwm ntev, thiab kev sib raug zoo nrog ib puag ncig thiab tus nqi.Faced nrog ntau yam kev thov scenarios thiab puas tau -ua kom muaj kev xav tau, kev xaiv cov khoom siv suab nrov tau dhau los ua ib qho tseem ceeb ntawm laj kab tsim thiab kev siv, yuav tsum tau xav txog kev ua tau zoo, kev ua tau zoo thiab ib puag ncig.
Cov ntaub ntawv hlau tseem tuav txoj haujlwm tseem ceeb hauv kev lag luam laj kab, tshwj xeeb yog hlau thiab txhuas alloys. Hlau muaj lub zog siab thiab nruj, ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev cuam tshuam loj lossis kev thauj khoom tsis zoo, xws li thaj chaw muaj kev lag luam thiab kev thaiv tsheb. Txawm li cas los xij, nws qhov kev tiv thaiv corrosion yuav tsum tau kho saum npoo xws li kub -dip galvanizing, hmoov txheej, lossis fluorocarbon txheej los txhim kho huab cua tiv thaiv. Aluminium alloys, ntawm qhov tod tes, yog lub teeb yuag thiab corrosion-resistant, yooj yim rau kev thauj mus los thiab kev teeb tsa. Lawv feem ntau siv nyob rau hauv toj roob hauv pes los yog ib ncig ntawm cov qauv rhiab rau lawv tus kheej qhov hnyav. Thaum lawv lub zog qis dua cov hlau me ntsis, kev ua kom zoo hla - ntu thiab kev txhawb nqa cov tav tuaj yeem ua tau raws li kev ruaj ntseg feem ntau.
Daim ntawv thov ntawm polymers thiab cov ntaub ntawv sib xyaw yog nthuav. Hloov cov yas xws li polyethylene thiab polypropylene muaj cov tshuaj tiv thaiv zoo heev thiab rwb thaiv tsev, ua rau lawv haum rau cov av noo, saline, lossis tshuaj lom neeg ib puag ncig. Lawv cov txheej txheem molding yog hloov tau, tso cai rau lawv ua rau hauv mesh, daim ntawv, lossis cov seem tsis tu ncua kom tau raws li cov kev xav pom thiab ua haujlwm. Cov iav fiber ntau reinforced plastics (FRP) muab lub teeb yuag thiab lub zog siab, ua kom pom kev zoo dua qub thiab ruaj khov nyob rau hauv siab - av noo, siab - ntsev ntug dej hiav txwv ib puag ncig. Lawv tuaj yeem tsim los ua pob tshab lossis ib nrab-cov ntawv pob tshab, ntsuas kev tiv thaiv thiab pom kev.
Ntoo, raws li cov khoom siv ib txwm siv, feem ntau yog siv hauv vaj thiab toj roob hauv pes laj kab vim nws qhov kev ntxhib los mos thiab eco- tus phooj ywg zoo. Txawm li cas los xij, ntoo raug cuam tshuam los ntawm kev tawg lossis tawg los ntawm cov av noo hloov pauv, xav tau kev kho mob nrog cov tshuaj tua kab mob, carbonization, lossis cov tshuaj tiv thaiv ib puag ncig, nrog rau kev saib xyuas tsis tu ncua thaum siv. Xyoob, kuj yog ib qho khoom siv dua tshiab, muaj cov tawv tawv zoo. Tom qab siab - kub nias thiab kab - pov thawj kev kho mob, nws tuaj yeem siv rau kev sib cais sib cais thiab zoo nkauj fencing, embodying qis - carbon mus kom ze.
Cov pob zeb thiab pob zeb feem ntau yog siv rau cov ciam teb ruaj khov thiab cov toj roob hauv pes enclosures, muab lub zog compressive siab thiab kev saib xyuas ntev - lub sijhawm pub dawb. Txawm li cas los xij, lawv hnyav, muaj lub voj voog siv ntev, thiab xav tau siab - lub hauv paus zoo. Cov txheej txheem Prefabrication feem ntau yog siv los txhim kho kev ua haujlwm. Eco- cov ntaub ntawv tus phooj ywg, xws li biodegradable polymer mesh ua ke nrog cov nroj tsuag nce toj kev txhawb nqa, tuaj yeem txhawb kev sib txawv ntawm biodiversity thiab ib puag ncig kev koom ua ke thaum ua tiav kev sib cais.
Kev xaiv cov khoom yuav tsum xub xav txog qhov kev ua haujlwm thiab kev siv tshuab ntawm cov ntaub ntawv siv. Qhov thib ob, nws yuav tsum ntsuas qhov cuam tshuam ntawm huab cua hauv zos, tshuaj lom neeg xov xwm, thiab kev saib xyuas cov xwm txheej ntawm kev ua haujlwm ntev. Thaum kawg, kev txiav txim siab yuav tsum tau txiav txim siab txog lub neej- cov nqi voj voog thiab cov ntsuas ib puag ncig. Nyob rau hauv cov ntsiab lus ntawm kev loj hlob ntsuab, qhov tseem ceeb ntawm kev rov ua dua tshiab thiab qis dua - cov khoom siv hluav taws xob thiab cov txheej txheem pab txhawb kev sib koom ua ke txhawb kev siv laj kab thiab kev tsim kho kom ruaj khov. Kev txiav txim siab ntawm cov ntaub ntawv tshawb fawb yog qhov tseem ceeb lav rau kev ua kom ntev - kev cia siab rau lub sijhawm, kev ua haujlwm ntawm kev lag luam, thiab kev ua phooj ywg ib puag ncig ntawm laj kab.
