IHBD60-Udidiibhulorho yavela eJamani kwaye yaziswa eTshayina ngemveliso yobuninzi ngohlalutyo lwesakhiwo sayo ziinjineli zeGreat Wall.

Intshayelelo yeHBD60-Udidiibhulorho isukela kwizithintelo zobugcisa kunye nokusilela kweBailey Bridge. Njengoko yaziwa kubo bonke, i-Belle Bridge sisakhiwo esiqhelekileyo sebhulorho yentsimbi, engumqadi webhulorho ephezulu kunye nesezantsi kunye nepini enye edibanisa iyunithi ye-truss njengowona mqadi wesakhiwo sebhulorho, enezibonelelo zesakhiwo esilula, ukuguquguquka okunamandla kunye nokutshintshiselana okulungileyo. Kodwa nokuba umthwalo awukho mkhulu, unokufikelela kwiimitha ezingama-60 kuphela kwisithuba esinye.

Ngoko ke,Iqela elikhulu leDongauqalise iHBD60-Udidiibhulorho. Nangona i-truss ithatha intsimbi enkulu, isakhiwo silula, esingenayo nje inzuzo yokuguquguquka okuqinileyo kwebhulorho yentsimbi yeBailey, kodwa yenza umda wexesha, iphucula ubude bexesha elinye kwaye igcine iindleko zebhulorho yokukhwela. .

HBD60uhloboumqadi wentsimbi owenziwe ngaphambili udla ngokuthatha ukrozo oluphindwe kabini oluqinisiweyo kunye nesixhobo sesithathu, esidityaniswe kumacandelo asemgangathweni anje ngeentsimbi zokuphela, iisegmenti zetruss eziqhelekileyo, iichords, iichords eziqinisiweyo, iichords zesithathu, imiqadi enqamlezileyo, imiqobo yokubopha umoya, kunye nezixhaso ezithe nkqo. I-truss ephambili idibaniswe ngamabholithi aphezulu. I-truss eqhelekileyo yi-3.048m ubude, kunye nobude obuyi-2.250m kunye nobude obuphindwe kabini be-4.500m. Kukho iitrasi ezimbini kwelinye icala, kwaye indlela yenqwelo ithatha indawo eyomeleziweyo yebhulorho yekhonkrithi okanye umgangatho webhulorho yentsimbi.

UThutho kunye noGcino lwe-HBD60 UhloboIibhulorho zeZakhiwo zeNsimbi

I-1) Ngexesha lokulayishwa, ukuthutha, kunye nokukhulula inkqubo yamacandelo ngexesha lokuthunyelwa, kuyimfuneko ukuphepha ukulimaza ifilimu yepeyinti, kunye nomonakalo wokungqubana kunye nokuguqulwa kwamacandelo.

2) Iindlela ezininzi zothutho kufuneka zisetyenziselwe ukuthuthwa kwecandelo, kwaye kungakhathaliseki ukuba yiyiphi enye esetyenziswayo, ukuthutha okuphakathi kufuneka kuncitshiswe.

3) Xa amacandelo okuthumela, umenzi kufuneka anike umsebenzisi isatifikethi somgangatho wemveliso, uluhlu lwamacandelo emveliso, kunye nemiyalelo yokusebenzisa ibhuloho yensimbi.

I-4) Ukugcinwa kweebhulorho zetsimbi kufuneka kuqhutywe kwiindawo zokugcina iimpahla, kwaye ulawulo lwazo kufuneka luqhutywe ngokuhambelana nemimiselo efanelekileyo yeMithetho yoLawulo lweeNdawo zoThutho lwezoThutho lweSizwe kunye neNcwadi yoLawulo yeSizwe soKhuseleko lwezoThutho lweMpahla yokugcina izinto. .

5) Ukuqinisekisa uxhulumaniso olugudileyo lweebholiti eziphakamileyo phakathi kwamacandelo ebhulorho yensimbi, iyunithi yokucubungula kufuneka ithathe amanyathelo asebenzayo kunye anokwenzeka ukukhusela i-deformation yecandelo ngexesha lokugcinwa kunye nokuthuthwa kwamacandelo ebhulorho yensimbi.

6) Ngexesha lokugcinwa kunye nokuthuthwa kwamacandelo, ingqwalasela kufuneka ihlawulwe ekukhuselweni kwesakhiwo sensimbi yokugqoka indawo. Ukuba kukho nawuphi na umonakalo, kufuneka ulungiswe ngexesha elifanelekileyo. Iyunithi yokucubungula kufuneka iphuhlise inkqubo yokulungiswa kwendawo yokugubungela ehlangabezana neemfuno zethu zokwakha.
