Ngeke kube namaphutha eziqondisweni ze-longitudinal kanye ne-longitudinal zonqenqema.Ngakho-ke, kuphela ngokuthola isikhundla sekholomu ngokusho komgwaqo, kungaqinisekiswa ukuthi ngeke kube namaphutha ekuqondeni kwenetha elivikelayo ekuqondeni kwe-longitudinal (ngendlela).Ngakho-ke, ku-longitudinal ( Endleleni), ngeke kube nephutha ekubekweni konqenqema, futhi ngeke kube nephutha ekuqondisweni kwenetha lokuvikela, futhi ngeke kube khona ukuphambuka ku-longitudinal kanye ne-longitudinal. izikhombisi-ndlela.

1. Okokuqala, thola ibanga eliphakathi kwamakholomu, futhi uthathe amabhuloho omgwaqo omkhulu, izindawo zokuphuma zokuphepha, izimbobo ezinezikhala ezivikelekile ezigudlukayo, ama-viaducts, neziphambano zeleveli njengezinga elisukela nge-laser.Kunezinhlobo ezimbili zezikhala zekholomu: 2 m kanye no-4 m.Isikhala esingu-2 m yikholomu ephakanyisiwe, kanti isikhala esingu-4 m yikholomu evamile.Kodwa-ke, ohlelweni lwangempela lokwakhiwa kobunjiniyela, ukuhlukaniswa okungajwayelekile kuvame ukwenzeka.Indawo yokufaka ibhodi ayiqinisekile, ngakho-ke zama ukugwema izikhala ezimise okukhethekile lapho unquma ukuhlukana kwamakholomu.
2. Ukuma okuqondile: okokuqala, dweba umugqa oqondile ngepensela elibomvu onqenqemeni ngokwebanga eliphakathi kwamakholomu, bese usebenzisa intambo nesipikili ukubeka umugqa endleleni, lungisa umugqa ngokuqhubekayo, bese usebenzisa. ipensela elibomvu ukuthola umugqa oqondile oqondile ukuya kumugqa ohambisanayo emugqeni.Ulayini, bese uthola umugqa oqondile emugqeni ovundlile oqonde ngqo kumugqa ovundlile, bese ubeka umugqa oqondile oqonde kumugqa ovundlile, ukuze uqinisekise ukuthi umugqa ovundlile womugqa ovundlile uqondile. emgqeni ovundlile.
3. Ubude bekholomu yokulawula: Ukuthi usilingi womhlobiso wekholomu uzinzile yini, ukuzinza kodonga lwe-guardrail yesivinini esikhulu kunquma ubude obuphelele bekholomu, okuyisici esiphezulu kakhulu somonakalo womugqa wekholomu emelene nokungqubuzana.Enqubweni yokuqala yokwakha yephrojekthi yekholomu ephikisana nokushayisana, sicabange ukuthi itshe lonqenqema ngokungangabazeki lisendaweni ephakeme ngokuphelele.Ngokwemidwebo yokwakha, ukuphakama kwesakhiwo sodonga lwekholomu kuphakeme ngo-1750 px kunetshe lonqenqema.Lapho kufakwa ikholomu yokuqala, ikholomu ngayinye Isekelwe ekuphakameni okuphelele, ngokusho kwemidwebo yokwakha, udonga olulodwa luphakeme ngo-1750 px kunonqenqema, bese kuba iposi ngalinye liyashaywa, lapho isando senqwaba siwela ensikeni, okuthunyelwe ngakunye. kumele ishaywe esigxotsheni, bese Hit ikholomu kukholamu, bese ushaya ikholomu kukholamu, bese wenza ukuphakama kwekholomu kube ukuphakama okuphelele, ngokusho kwemidwebo yokwakha, ukuphakama kwekholomu kuphakeme kakhulu, futhi ikholomu ngayinye kufanele ibe phezulu
4. Ukungazinzi kodonga lwamatshe onqenqemeni olujwayelekile kubonakala odongeni lwekholomu, okugcina kubangela ukungazinzi okuphelele kwe-high-speed guardrail.Ngenxa yenani lamakholomu, kunzima kakhulu ukulungisa, futhi indlela elandelayo yokulawula ukuphakama okuphelele kodonga lwekholomu isetshenziswa., qala ngokubala ukuphakama okuphelele kodonga lwamatshe onqenqemeni ngokusekelwe ekuphakameni okuphelele kwendawo yomgwaqo, bese ubala ukuphakama kwesakhiwo sodonga lwekholomu ngokweqiniso lokuthi udonga lwekholomu kufanele lube ngo-1750px ngaphezu kodonga lwamatshe onqenqemeni, futhi bese ukala ngokunembile ikholomu ngayinye lapho ufaka ikholomu.
