Iimpawu zekholamu enye zibhekisa kwiimpawu zendlela ezifakwe kwiipali enye, ifanelekile kwiimpawu zesilumkiso eziphakathi ukuya kwezincinci, ezithintelayo, kunye nemiyalelo, kunye neempawu ezincinci zesikhokelo. Umphetho wangaphakathi wophawu lwendlela olufakelweyo olufana neekholamu akufuneki lungene kwindawo evulekileyo yokwakhiwa kwendlela, kwaye ngokubanzi alukho ngaphantsi kwama-25cm ukusuka kumphetho wangaphandle wendlela okanye indawo yokunqumla yabahambi ngeenyawo okanye egxalabeni. Umphetho ongezantsi wophawu lwendlela uhlala kwi-150-250cm ukusuka emhlabeni. Xa lufakelwe kwiindlela zikamasipala ezinenani elikhulu leemoto zabakhweli, ukuphakama komphetho ongezantsi ukusuka kumphezulu wendlela kunokuncipha ngokuxhomekeke kwimeko ethile, kodwa akufuneki kube ngaphantsi kwe-120cm; xa lufakelwe ecaleni kwendlela kunye neendlela zezithuthi ezingezizo iimoto, ukuphakama kufuneka kudlule kwi-180cm.
Iimpawu ezinekholamu enye zihlala zisetyenziswa kwiindlela zephondo, kwiindlela zikazwelonke, kwiindlela ezinkulu, kwiindlela zasezidolophini, kwiindawo zokuhlala, ezibhedlele nakwiindawo zokupaka iimoto ezingaphantsi komhlaba.
Iziseko zeepali zeempawu zendlela zifakwa endaweni yazo ngokweemfuno zoyilo, kwaye ulawulo lwazo lomgangatho lubonakala kakhulu kuyilo lomxube wekhonkrithi. Ikhonkrithi kufuneka ixutywe ngokwesilinganiso somxube wedaka lokwakha. Inxalenye eveziweyo yomphezulu wendlela phezulu kwesiseko ngasinye kufuneka yakhiwe ngokuhambelana nemizobo yobunjineli kunye neenkcukacha zobugcisa. Ulungiselelo olusisiseko lokuqinisa isakhiwo, kunye neenkcukacha zecandelo ngalinye, kufuneka zihambelane nemizobo yobunjineli. Ucingo lwesinyithi olubhityileyo lobubanzi obufunekayo kufuneka lusetyenziswe ukukhusela iindlela zokuhlangana kweebha zokuqinisa ezithe tye nezithe nkqo, ukuqinisekisa ukuba akukho kurhuqwa okanye ukungahoywa. Imizobo yobunjineli kufuneka ilandelwe xa kubekwa iiflange zesiseko. Iincopho zeeflange zesiseko kufuneka zihlanjululwe neencopho zeendonga zesiseko sekhonkrithi, kwaye kufuneka zihambelane nesiseko. Ubude obuveziweyo beebholiti zeankile ezifakwe ngaphakathi kufuneka bulawulwe phakathi kwe-10 kunye ne-20 cm, kwaye kufuneka zibotshelelwe ngokuthe nkqo kwiiflange zesiseko.
Ikhonkrithi eqinileyo kufuneka igalelwe kumphezulu womngxuma wesiseko ongagutyungelwanga. Amandla okuxinwa kwekhonkrithi egalelweyo kufuneka ahlangabezane neemfuno zoyilo. Emva kokuba umngxuma wesiseko ugrunjiwe, ikhonkrithi kufuneka igalelwe kungekapheli usuku.
Ukuxinana okungcangcazelayo kubalulekile xa kugalelwa ikhonkrithi. Ukuqinisekisa ukuba i-concrete ixinene ngokulinganayo kwaye kuthintelwe ukufuduka kwe-formwork, ukuxinana kufuneka kwenziwe ngokulandelelana kusetyenziswa izixhobo zoomatshini okanye umsebenzi wabantu. Qinisekisa ukuba ii-anchor bolts kunye ne-base flanges zibekwe ngokuchanekileyo ngexesha lokungcangcazela.
Zonke iikona eziveziweyo mazilungiswe kakuhle zibe nombala wekhonkrithi ofanayo, kwaye umphezulu wodonga olusisiseko kufuneka ulungiswe kakuhle. Umphezulu wekhonkrithi kufuneka ube bushelelezi kwaye ulingane, ungabi namabala angalinganiyo okanye afana nehoneycomb. Emva kokugalela, qiniseka ukuba ikhonkrithi iyahlangabezana neemfuno zokuyilungisa kwaye uhlale kude nelanga elithe ngqo.
Ukuqinisekisa ukuba i-engile yokufakelwa kweempawu zekholamu ezimbini iyahlangabezana neemfuno, i-axis phakathi kweziseko ezimbini kufuneka ilawulwe ngononophelo ngexesha lokwakhiwa kweziseko zezibonakaliso zekholamu ezimbini, ingakumbi xa iziseko ezimbini zinobude obahlukeneyo.
Ukuqinisekisa ukufakwa ngokufanelekileyo kwemiqadi ethwala umthwalo wesibonakaliso se-gantry, isithuba phakathi kweziseko kunye nomgca osembindini kufuneka silawulwe ngononophelo ngexesha lokwakhiwa kweziseko zesibonakaliso se-gantry. Kufuneka sisekelwe kwiinkcukacha ezithile kunye nomzekelo we-gantry frame beam ethwala umthwalo.
I-Qixiang yinkampani eyenzaiipali zeempawu zendlelaUkongeza kwiimpawu ezibonisa umgangatho wesizwe, umzi-mveliso wethu ugxile kwiipali zeempawu ze-cantilever, ezinekholamu ephindwe kabini, kunye neepali zezibonakaliso zekholamu enye. Ubukhulu, iipateni, kunye nobukhulu obulungiselelwe wena ziyaxhaswa. Sinexesha lokuhambisa elikhawulezayo, umgca wethu omkhulu wemveliso, kunye nempahla eninzi. Simema abathengi abatsha nabangoku ukuba banxibelelane nathi ukuze bafumane ulwazi oluthe kratya!
