Umnatha wentsimbi, njengesixhobo esibalulekileyo sokwakha, udlala indima ebalulekileyo kwiiprojekthi zokwakha zale mihla. Isakhiwo sayo esiyingqayizivele kunye nokusebenza okuphezulu kwenza kube yinto ekhethiweyo yokuqinisa izakhiwo, ukuphucula amandla okuthwala kunye nokuzinza. Eli nqaku liza kuhlalutya ngokubanzi izixhobo, iinkqubo zokuvelisa, iimpawu zesakhiwo kunye nemimandla yesicelo se-mesh yensimbi, kunye nokukhokelela abafundi ukuba babe nokuqonda okunzulu kwesi sixhobo sokwakha umlingo.
Ukukhetha izinto eziphathekayo kunye neempawu
Eyona mathiriyeli ekrwada yeumnatha wentsimbizibandakanya intsimbi eqhelekileyo ye-carbon structural, i-high-corrosion-resistant steel, i-high-temperature alloy steel, njl. Ezi zixhobo ziqinisekisa ukuqina, ukuxhathisa kwe-corrosion kunye namandla onke kunye nokuqina kwe-mesh yensimbi. Ngokukodwa, ukusetyenziswa kwentsimbi ephezulu enganyangekiyo kwi-corrosion kunye ne-high-temperature alloy iron yenza ukuba i-mesh yensimbi igcine ukusebenza okugqwesileyo kwiindawo ezifumileyo okanye ezonakalisayo.
Izinto ze-mesh zensimbi zikwabandakanya i-CRB550 yebakala le-CRB550 yeentsimbi zentsimbi epholileyo, i-HRB400 yebakala eshushu-i-ribbed metal bar, njl
Inkqubo yokuvelisa kunye neteknoloji
Inkqubo yokwenziwa kwe-mesh yentsimbi igubungela amakhonkco amaninzi afana nokulungiswa kwempahla ekrwada, ukusetyenzwa kwentsimbi yentsimbi, ukuwelda okanye ukuluka, ukuhlola kunye nokupakishwa. Okokuqala, intsimbi ekumgangatho ophezulu ehlangabezana nemigangatho yelizwe ikhethwa njengento ekrwada. Emva kokucubungula kwangaphambili njengokusika kunye nokulungelelanisa, ingena kwinqanaba le-welding okanye lokuluka.
Umnatha odityanisiweyo wamkela izixhobo zemveliso ezizenzekelayo ezizenzekelayo ukuwelda imivalo yentsimbi kunye ngokwesithuba esisetwe ngaphambili kunye neeengile ukwenza umnatha ngokuchaneka okuphezulu kunye nobukhulu obufanayo bomnatha. Le nkqubo yokuvelisa ayiphuculi kuphela ukusebenza kakuhle kwemveliso, kodwa iqinisekisa ukuqina kwendawo ye-welding kunye nokuchaneka kobukhulu be-mesh.
Umnatha olukiweyo usebenzisa inkqubo ekhethekileyo yokuluka ukuluka imivalo yentsimbi ecikizekileyo okanye iingcingo zentsimbi kwisakhiwo somnatha. Le nkqubo yokuvelisa ilungele ukwakha kunye neendleko eziphantsi, kwaye ifanelekile ukuqinisa izinto ezindongeni, ii-slabs zomgangatho kunye nezinye iindawo.
Iimpawu zesakhiwo kunye neenzuzo
Iimpawu zesakhiwo se-mesh yensimbi zibonakaliswa ikakhulu kwisakhiwo sayo segridi. Imivalo yentsimbi emide kunye ne-transverse igxininiswe ukwenza isakhiwo senqwelomoya kunye negridi eqhelekileyo. Esi sakhiwo sinokusasaza uxinzelelo ngakumbi kwaye sinciphise uxinzelelo lwengingqi, ngaloo ndlela kuphuculwe amandla kunye nokuzinza kwesakhiwo.
Izibonelelo ze-mesh yensimbi zibonakaliswa ikakhulu kule miba ilandelayo:
Phucula amandla olwakhiwo:Ukwakhiwa kwe-mesh ye-mesh yensimbi kunokunyusa umthamo wokuthwala ikhonkrithi kunye nokunciphisa i-deformation kunye nokuqhekeka.
Yandisa ukuqina kwesakhiwo:Ubunzima be-mesh yensimbi bukhulu, obunokuphucula kakhulu ubunzima obupheleleyo besakhiwo.
Phucula ukusebenza kwenyikima:I-mesh yensimbi inokuthintela ngokufanelekileyo i-deformation yekhonkrithi kunye nokunciphisa umonakalo wempembelelo yamaza e-seismic kwisakhiwo.
Yongeza ukuqina:I-mesh yensimbi ephathwe ngokukodwa (efana ne-galvanized) inokumelana ne-corrosion egqwesileyo kwaye inokwandisa ubomi benkonzo yesakhiwo.
Iinkalo zesicelo kunye namatyala
Intsimi yesicelo se-mesh yensimbi ibanzi, igubungela amashishini amaninzi afana nokwakha, ukuthutha, kunye nokugcinwa kwamanzi. Kwintsimi yokwakha, i-mesh yensimbi isetyenziswa ngokubanzi ekuqiniseni i-slabs yomgangatho, iindonga kunye nezinye iindawo zesakhiwo sezakhiwo eziphakamileyo, izakhiwo zokuhlala ezinamabali amaninzi kunye nezinye iiprojekthi. Kwintsimi yezothutho, i-mesh yensimbi isetyenziselwa ukuqinisa iindlela zokuhamba zendlela, iidekhi zebhulorho kunye nezinye iiprojekthi ukuphucula umthamo wokuthwala kunye nokuzinza kwendlela yokuhamba. Kwintsimi yokugcinwa kwamanzi, i-mesh yensimbi isetyenziselwa ukuqinisa izixhobo zokulondoloza amanzi ezifana namadama okugcinwa kwamanzi kunye ne-embankments ukuphucula uzinzo jikelele.
Imizekelo ethile ibandakanya: Kwizakhiwo eziphakamileyo, i-mesh yensimbi isetyenziselwa ukuqinisa i-slabs floor, iindonga kunye nezinye iindawo zesakhiwo, ukuphucula ukumelana nokuzamazama komhlaba kunye nokuthwala umthamo wesakhiwo; kwiiprojekthi zohola wendlela kunye neebhulorho, i-mesh yensimbi isetyenziswa ngokubanzi ukunyusa umthamo wokuthwala kunye nokuzinza kwendawo yendlela, ukuthintela ngokufanelekileyo iingxaki ezifana nokuqhekeka kwendlela kunye nokuhlaliswa; kwiiprojekthi zetonela kunye ne-subway, i-mesh yentsimbi isetyenziswa njengesixhobo esiphambili sokuphucula ukunganyanzeki kwesakhiwo kunye nokumelana nokuqhekeka.
