Yintoni esifanele sinikele ingqalelo kuyo xa silungisa ukuthwala kunye nesiseko sebhulorho yeBailey?

Ngenxa yesakhiwo sayo esilula, ukumiswa ngokukhawuleza, ukutshintshiselana okulungileyo kunye nokuguquguquka okuqinileyo, i-Bailey Bridge isetyenziswa ngokubanzi kubomi bemihla ngemihla. Ke yintoni ekufuneka sinikele ingqalelo kuyo xa silungisa ukuthwala kunye nesiseko sebhulorho yeBailey?

1. Xa iBailey Bridgeityhalelwe kwindawo emiselweyo, umqadi wesikhokelo uya kususwa kwaye ikholamu yokugqibela ifakwe ukulungiselela ibhulorho kwindawo. Xa isendaweni, phakamisa ibhulorho esezantsi ngejekhi, susa iliwa kunye nepleyiti yesampulu, hambisa ibhulorho phantsi kwelitye uye kwipleyiti yesitulo esele ifakwe ngaphambili; uze uwele ibhulorho ngokucothayo kwisihlalo sebhulorho. Ipleyiti yentsimbi eshinyeneyo iya kubekwa phakathi kwejekhi kunye nebha yomtya esezantsi ukusabalalisa umthwalo phezu kweegrooves ezimbini zebha yomtya. Isikhundla sayo sibekwe kakuhle kwindawo yokudibanisa i-truss string pole kunye ne-bailey pole.

2. Xa ibhulorho ihla, isantya sokumisa i-jack nganye kufuneka ihambelane, ukuze ungagxininisi ubunzima bebhulorho kwi-jack ethile, ebangela umonakalo kwi-jack okanye i-truss string rod kunye nezinye iingozi ezinzulu. Kwi-span encinci kunye neebhulorho ezinobunzima, ii-crowbars zingasetyenziswa. Nokuba yeyiphi na indlela, kufuneka uqale uhlale kwibhanki enye kwaye kwenye ibhanki. Xa yakhiwe kumhlaba othambekileyo, ijekhi kufuneka ibekwe ngokuqinileyo, ukuthintela ukutyibilika.Kwangaxeshanye, 1-2 abaqhubi kufuneka babelwe kwelinye iliwa lebhanki ukujonga ukuba kukho nasiphi na isiphoso, ukuba ibhulorho ivaliwe okanye i-offset. inkqubo yokuphehlelelwa; jongana neengxaki ngexesha, nqumamisa ukuqaliswa ukuba kuyimfuneko, sebenzisa i-jack ukuphakamisa ibhulorho kwaye uhambise i-roller. i-truss iqhutywe kwindawo yokulinganisa, enokulungiswa ngendlela yokutsala umsila.

3. Ukususwa kwebhuloho kufuneka kuqhutywe ngokulandelelana kwe-reverse yokwakhiwa. Xa umehluko wobude phakathi kwedekhi yebhulorho kunye ne-pavement ingaphantsi kwe-15 cm, ipleyiti enye yelap inokusekwa. Esinye isiphelo sepleyiti sibekwe ngaphakathi kweqhosha lomqadi, kwaye esinye isiphelo sibekwe endleleni, kodwa umqamelo kufuneka ufakwe ngezantsi. iipleyiti zomlenze kufuneka zifakwe. Xa isiza silinganiselwe, sinokutsalwa ngasemva ngelixa sichithwa, kwaye ke iitrasi kunye namanye amacandelo anokususwa nganye nganye. Susa umnyango kwaye uphume kuqala, emva koko uphezulu ekupheleni kwebhuloho ngejack, susa ikholamu yokuphela kunye nebhuloho, faka ilitye, kwaye ufake isiphelo sebhuloho; imiqadi kufuneka yongezwe phakathi kwamacwecwe amabini, kwaye inkxaso yeplate kufuneka ibekwe phantsi komqadi. I-truss itsalwa ngokucothayo ngasemva kunye nomntu okanye i-mechanical traction.Tsalo ngaxeshanye ukulawula ngokungqongqo ukutyhala kunye nesantya sokutsalwa, ukunyanzeliswa ukuba kufane, ukutyhala ukuba kucothise kwaye kugudiswe, kungacothi kakhulu okanye kukhawuleze kakhulu.

I uhola wendlela ibhulorho yentsimbi, ibhulorho yeBailey, i-Bailey beam kunye nezinye iimveliso eziveliswa yi-Great Wall Heavy Industry zinandipha igama elihle ekhaya nakwamanye amazwe, kwaye zithunyelwa kumazwe amaninzi.Injongo yethu kukuqonda iziphene ezikumgangatho ophezulu kunye nomthamo wemveliso, ngentliziyo epheleleyo ukubonelela. abathengi ngenkonzo ekumgangatho ophezulu, injongo yethu ishishini kukuba: ukubonelela abathengi ngeemveliso ezikumgangatho ophezulu, ukubonelela ababoneleli abaqeqeshiweyo, unxibelelwano oluthembekileyo. Wamkelekile abahlobo abavela kuzo zonke iinkalo zobomi ukuba beze kulingo, ukuze baseke unxibelelwano lwexesha elide lweshishini.
