Yintoni iYunithi yoThumelo loThutho/isixhobo sokutshixa?
Iyunithi yothumelo lomothuko (STU), ekwaziwa njengesixhobo sokutshixa (LUD), sisixhobo esidibanisa iiyunithi ezahlukeneyo zesakhiwo.Ibonakaliswe ngokukwazi ukuhambisa amandla eempembelelo zexesha elifutshane phakathi kwezakhiwo ezidibanisayo ngelixa livumela ukunyakaza kwexesha elide phakathi kwezakhiwo.Ingasetyenziselwa ukuqinisa iibhulorho kunye ne-viaducts, ngakumbi kwiimeko apho ukuphindaphinda, isantya kunye nobunzima bezithuthi kunye noololiwe baye banda ngaphaya kweendlela zokuqala zokuyilwa kwesakhiwo.Ingasetyenziselwa ukhuseleko lwezakhiwo kwiinyikima kwaye ineendleko zokonga i-seismic retrofitting.Xa isetyenziswe kuyilo olutsha ukonga okukhulu kunokufezekiswa ngeendlela eziqhelekileyo zokwakha.
Isebenza njani iyunithi yothumelo lweShock/Isixhobo sokutshixa?
Iyunithi yothutho yothutho / isixhobo sokutshixa siqukethe i-cylinder eyenziwe ngomatshini kunye nentonga yokuhambisa edityaniswe kwelinye icala ukuya kwisakhiwo kwaye kwelinye icala kwipiston ngaphakathi kwe-cylinder.I-medium ngaphakathi kwe-cylinder yi-silicone edibeneyo eyenziwe ngokukodwa, eyenzelwe ngokuchanekileyo iimpawu zokusebenza zeprojekthi ethile.Izinto ze-silicone ziyi-reverse thixotropic.Ngexesha lokunyakaza okucothayo okubangelwa utshintsho lobushushu kwisakhiwo okanye ukucutheka kunye nokunyuka kwexesha elide lekhonkrithi, i-silicone iyakwazi ukukhama ngevalve kwipiston kunye nesithuba phakathi kwepiston kunye nodonga lwesilinda.Ngokulungisa imvume efunwayo phakathi kwepiston kunye nodonga lwesilinda, iimpawu ezahlukeneyo zinokufezekiswa.Umthwalo wequbuliso ubangela ukuba intonga yokuhambisa ikhawuleze nge-silicone compound ngaphakathi kwe-cylinder.Ukukhawuleza kudala isantya kwaye kwenza ivalve ivalwe apho i-silicone ayinakudlula ngokukhawuleza ngokwaneleyo malunga nepiston.Ngeli xesha isixhobo siyatshixa, ngokuqhelekileyo ngaphakathi kwesiqingatha sesibini.
Apho iyunithi yothumelo lothuso/isixhobo sokutshixa sisebenza kuso?
1, iCable Stayed Bridge
Iibhulorho ezinkulu ezibanzi zihlala zineendawo zokufuduka ezinkulu kakhulu ngenxa yeentshukumo zenyikima.Uyilo olufanelekileyo lwesithuba esikhulu lunokuba nenqaba edityanisiweyo kunye nedesika yokunciphisa oku kufuduswa kukhulu.Nangona kunjalo, xa inqaba idityanisiwe kunye nedekhi, amandla okunciphisa kunye nokunyuka, kunye ne-gradients ezishisayo, zichaphazela kakhulu inqaba.Luyilo olulula kakhulu ukudibanisa umgangatho kunye nenqaba kunye ne-STU, ukudala umdibaniso osisigxina xa ufunwa kodwa uvumela umgangatho ukuba uhambe ngokukhululekileyo ngexesha lemisebenzi eqhelekileyo.Oku kunciphisa iindleko zenqaba kwaye okwangoku, ngenxa ye-LUDs, kuphelisa ukufuduka okukhulu.Kutshanje, zonke izakhiwo ezikhulu ezinexesha elide zisebenzisa i-LUD.
I-2, iBhulorho yeGirder eqhubekayo
Ibhulorho yokudibanisa eqhubekayo inokujongwa njengebhulorho yebhanti ene-span eqhubekayo.Kukho i-pier enye kuphela emiselweyo ekufuneka ithathe yonke imithwalo.Kwiibhulorho ezininzi, i-pier esisigxina ayikwazi ukumelana namandla eengcamango zenyikima.Isisombululo esilula kukongeza ii-LUD kwiindawo zokwandisa ukuze zontathu ii-piers kunye nee-abutments zabelane ngomthwalo we-seismic.Ukongezwa kwee-LUDs kuxabisa kakhulu xa kuthelekiswa nokomeleza i-pier esisigxina.
3, iBhulorho ye-Span enye
Ibhulorho ye-span elula yibhulorho efanelekileyo apho i-LUD inokudala ukomelezwa ngokwabelana ngomthwalo.
I-4, i-Anti-seismic retrofit kunye nokuqiniswa kweebhulorho
I-LUD inokudlala indima ebalulekileyo ekuncedeni injineli ekuphuculeni isakhiwo ngexabiso elincinci lokuqiniswa kwe-anti-seismic.Ukongeza, iibhulorho zinokomelezwa ngokuchasene nemithwalo yomoya, isantya, kunye nemikhosi yokuqhokra.
