Izibonda zokujongaZisetyenziswa kakhulu kubomi bemihla ngemihla kwaye zifumaneka kwiindawo ezingaphandle ezifana neendlela, iindawo zokuhlala, iindawo ezintle, izikwere, kunye nezikhululo zikaloliwe. Xa kufakwa iipali zokujonga, kukho iingxaki zokuthutha kunye nokulayisha, kunye nokukhulula impahla. Ishishini lezothutho lineenkcukacha zalo kunye neemfuno zeemveliso ezithile zothutho. Namhlanje, inkampani yeepali zentsimbi iQixiang iza kwazisa amanyathelo athile okhuseleko malunga nokuthuthwa kunye nokulayisha, kunye nokukhulula iipali zokujonga.
Amanyathelo okuthuthwa kunye nokulayisha kunye nokukhupha iipali zokubeka esweni:
1. Inxalenye yelori esetyenziselwa ukuthutha iipali zokujonga kufuneka ibe nee-guardrails ezidityanisiweyo ezinde nge-1 m kumacala omabini, ezine kwicala ngalinye. Umgangatho wenxalenye yelori kunye nomaleko ngamnye weepali zokujonga kufuneka zahlulwe ngamaplanga omthi, ayi-1.5 m ngaphakathi kwesiphelo ngasinye.
2. Indawo yokugcina izinto ngexesha lokuthuthwa kufuneka ibe tyaba ukuqinisekisa ukuba umaleko osezantsi weepali zokujonga usekelwe ngokupheleleyo kwaye ulayishwe ngokulinganayo.
3. Emva kokulayisha, qinisa iipali ngentambo yocingo ukuze zingaqengqeleki ngenxa yokuguquguquka ngexesha lokuthuthwa. Xa ulayisha kwaye ukhulula iipali zokujonga, sebenzisa i-crane ukuziphakamisa. Sebenzisa iindawo ezimbini zokuphakamisa ngexesha lenkqubo yokuphakamisa, kwaye ungaphakamisi iipali ezingaphezulu kwezimbini ngexesha. Ngexesha lokusebenza, kuphephe ukungqubana, ukuwa ngequbuliso, kunye nokuphakamisa okungafanelekanga. Musa ukuvumela iipali zokujonga ukuba ziqengqeleke ngqo emotweni.
4. Xa ukhulula, musa ukupaka kwindawo ethe tyaba. Emva kokukhulula ipali nganye, qinisa iipali eziseleyo. Nje ukuba ipali ikhululwe, qinisa iipali eziseleyo ngaphambi kokuba uqhubeke nokuthutha. Xa zibekwe kwindawo yokwakha, iipali mazilingane. Vimba amacala ngokukhuselekileyo ngamatye kwaye uphephe ukuqengqeleka.
Iipali zokujonga zinezicelo ezintathu eziphambili:
1. Iindawo zokuhlala: Iipali zokujonga kwiindawo zokuhlala zisetyenziselwa ikakhulu ukujonga nokuthintela ubusela. Ngenxa yokuba indawo yokujonga ijikelezwe yimithi kwaye igcwele izindlu nezakhiwo, ukuphakama kweepali ezisetyenzisiweyo kufuneka kube phakathi kweemitha eziyi-2.5 nezi-4.
2. Indlela: Iipali zokujonga indlela zingahlulwahlulwa zibe ziintlobo ezimbini. Uhlobo olunye lufakelwa ecaleni kweendlela ezinkulu. Ezi pali zingaphezulu kweemitha ezi-5 ubude, kwaye ukhetho luqala kwiimitha ezi-6, 7, 8, 9, 10, kunye ne-12. Ubude bengalo buhlala buphakathi kwemitha e-1 kunye ne-1.5. Ezi pali zinemfuno ezithile zezinto zokwakha kunye nomsebenzi. Ipali yemitha ezi-5 idla ngokufuna ububanzi bepali obuncinci obuyi-140 mm kunye nobukhulu bepali obuncinci obuyi-4 mm. Ipali yentsimbi eyi-165 mm idla ngokusetyenziswa. Izinto ezifakwe kwiipali ngexesha lokufakelwa ziyahluka ngokuxhomekeke kwiimeko zomhlaba kwindawo leyo, kunye nobunzulu obuncinci obuyi-800 mm kunye nobubanzi obuyi-600 mm.
3. Ipali yezibane zendlela: Olu hlobo lwepali yokujonga luneemfuno ezintsonkothileyo. Ngokubanzi, ukuphakama kwesiqu esiphambili kungaphantsi kweemitha ezi-5, ngokuqhelekileyo ziimitha ezi-5 ukuya kwiimitha ezi-6.5, kwaye ingalo isusela kwimitha e-1 ukuya kwiimitha ezili-12. Ubukhulu bepayipi yepali ethe nkqo bungaphantsi kwee-220 mm. Ipali yokujonga ingalo efunekayo yimitha ezili-12 ubude, kwaye isiqu esiphambili kufuneka sisebenzise ububanzi bepayipi obuyi-350 mm. Ubukhulu bepayipi yepali yokujonga bukwatshintsha ngenxa yokwandiswa kwengalo. Umzekelo, ubukhulu bepali yokujonga bungaphantsi kwee-6 mm.Izibonda zemiqondiso yendlelazidityaniswa nge-arc welding engaphantsi komhlaba.
