Ukufaka ii-Bollard Casings zoKhuseleko lweNsimbi: Isikhokelo soBunjineli

Imigangatho yoFakelo lweeNqanaba zeBollard zoKhuseleko lweNsimbi

Xa kufakwa ii-bollards zokhuseleko zentsimbi enzima—ingakumbi kwiindawo ezinzima ezifana nonxweme, unxweme lomlambo, okanye iindawo zoshishino ezifumileyo—ukuthembeka kwesiseko yeyona nto ibalulekileyo. I-bollard inamandla kuphela njengenkqubo yayo yokubambelela. Ukufaka kakuhle isigqubuthelo sokukhusela (isilingi) kuqinisekisa ukumelana nempembelelo ixesha elide kwaye kuthintela utshintsho lwesakhiwo ngokuhamba kwexesha.

Apha ngezantsi kukho isikhokelo sobuchwephesha sokufakela iibhokisi zentsimbi zokhuseleko kwiindawo ezahlukeneyo zomhlaba kunye neemeko zamanzi.

Ufakelo Lomhlaba Owomileyo Namanzi Anganzulu

Kwizinto ezisemgangathweni zokufakelwa emhlabeni owomileyo okanye emanzini anganzulu, ubunzulu bokufakelwa buxhomekeke ngqo kwisakhiwo somhlaba:

• Iileya Zomhlaba Ezingenakushukunyiswa (Udongwe/Umhlaba Oxineneyo):Ubunzulu bokungcwaba kwebhokisi kufuneka bubeI-1.0 ukuya kwi-1.5 iphindwe ubukhulu obungaphandleyebhokisi, enobunzulu obuncinci obungqongqoImitha eyi-1.0.

• Iileya Zomhlaba Ezingena Kumanzi (Isanti/Intlabathi):Sebenzisa umlinganiselo wobunzulu ofanayo nowentla. Nangona kunjalo, ukuthintela amanzi ukuba angonakalisi isiseko, gqobhoza uze ufake umhlaba onesihlabathi endaweni yawo ngodongwe oluxineneyo nolungangeni manzi. Olu donga lufanele lwandise ubuncinaneNgaphantsi kweemitha eziyi-0.5umda ongezantsi we-casing, kunye nobubanzi obungena endaweni yokubuyisela obudlula ububanzi be-casing nge0.5 ukuya kwi-1.0 yeemitha.

• Amanzi Anganzulu kunye Nomhlaba Ozinzileyo:Ukuba ubunzulu bamanzi bungaphantsi kweemitha ezi-3 kwaye akukho maleko we-silt obuthathaka, ungasebenzisaindlela evulekileyoQinisekisa ukuba udongwe olujikeleze ezantsi nasemacaleni ebhokisi luxinene kakuhle ngokweengqimba.

Amanzi anzulu, iDaka, kunye nemilambo ethambileyo

Kwiindawo ezifumileyo okanye ezimanzini, isingxobo kufuneka sidlule kwiileya zomphezulu othambileyo ukuze sibambelele kumhlaba othwala umthwalo:

• Idaka Elikhulu Nedaka Elithambileyo:Umphetho ongezantsi webhokisi kufuneka ungene nzulu kumaleko womhlaba ozinzileyo nongenamanzi. Ukuba akukho maleko ungangeniyo, ibhokisi kufuneka iqhube0.5 ukuya kwi-1.0 yeemithakwi-gravel exineneyo okanye kwi-pebble layer.

• Iibhedi zeMilambo ezisengozini yokutyiwa yiScour:Kwiindawo ezichaphazeleka yimisinga etshintshayo kunye nokukhukuliseka komhlaba, umzantsi webhokisi kufuneka uhlale ubuncinciImitha eyi-1.0 ngaphantsi komgca oqhelekileyo wokuskrolaKwiindawo ezijongene nokukhukuliseka okukhulu kwendawo, kufuneka ubuncinane kudluleImitha eyi-1.0 ngaphantsi komgca wokuskrola wendawo.

• Amanzi anzulu (Ngaphezulu kune-3m):Xa usebenza kubunzulu bamanzi obungaphezulu kweemitha ezi-3, qinisa i-casing usebenzisa iqonga lokusebenza elikhethekileyo kunye nesakhelo sesikhokelo. Yitshonise i-casing endaweni yayo usebenzisa iindlela zobungcali ezifana nokungcangcazela, ukubethela ngehammer, okanye ukuphosa amanzi.

Iindawo Ezinemozulu Embi Nezibandayo

Ukuhamba komhlaba okubangelwa kukuqhekeka kweqabaka kunokushenxisa iziseko ezinganzulu lula.

• Iindawo zokuQhotsa zeXesha:Umzantsi webhokisi kufuneka ungene ubuncinaneIimitha eziyi-0.5 kumhlaba ongakhenkceziswangangaphantsi komgca weqabaka wasekuhlaleni.

• Iindawo ezihlala zingumkhenkce:Ibhokisi kufuneka ingene ubuncinaneIimitha eziyi-0.5 ngqo kumaleko oqinileyo we-permafrostukugcina uzinzo kwisakhiwo.

Imigangatho yoKuphakama, uLungelelaniso, kunye noKunyamezela

Ukuchaneka ngexesha lenkqubo yokutshona kubalulekile ukuqinisekisa ukuba i-bollard ihlala imile ngokugqibeleleyo kwaye ibonakala kakhulu:

• Iimfuneko zoBude:Umphezulu webhokisi kufuneka uhlaleIimitha eziyi-2.0 ukuphakamangaphezu komgangatho wamanzi okwakha (okanye umgangatho wamanzi angaphantsi komhlaba), kwaye ubuncinci0.5 yeemitha ukuphakamangaphezu komhlaba wokwakha ogqityiweyo. Kufuneka ihambelane nokuphakama okufunekayo kwekhonkrithi yangaphakathi okanye inqanaba lodaka.

• Ulawulo lokuSinki (Kwizingxobo ezingaphantsi kwe-3m):Ukuba usebenzisa ihamile okanye ukungcangcazela ukuntywilisela isingxobo, jonga ngononophelo kwaye ulawule ulungelelwaniso oluthe tye, ukuthambekela okuthe nkqo, kunye nomgangatho woqhagamshelo lwamalungu.

• Ukunyamezelana Okuvumelekileyo:Kwisingxobo esisetwe ngokupheleleyo, ukuphambuka okuthe tye okuvumelekileyo komphezulu ophezulu50 mm, kwaye ukuphambuka okuthe nkqo okuphezulu okuvumelekileyo (ukuthambekela) yi1%.

Imigangatho yoShishino kunye neeReferensi zoBunjineli

Ukuqinisekisa ukuthotyelwa kwemigangatho yokhuseleko lwesakhiwo sehlabathi kunye nesiseko, ezi ndlela zokufakela zihambelana nezi zinto zilandelayo:

1. Iinkcukacha zoYilo lweBhuloho le-AASHTO LRFD:Lo mgangatho ubonelela ngezibalo zokulinganisa ukumelana nomhlaba ecaleni, izibalo zomgca wokukrwela, kunye nokuthembeka kwesakhiwo esisisiseko kwimisebenzi yoluntu.

2. I-ASTM D1143 / D1143M (Iindlela zoVavanyo eziQhelekileyo zeZiseko eziNzulu phantsi koMthwalo oQondisiweyo we-Static Axial):Lo mgangatho ulawula indlela iibhokisi kunye neenqwaba eziqhutywa nzulu eziziphatha ngayo phantsi komthwalo kwiintlobo ezahlukeneyo zomhlaba, ukuqinisekisa ukuba umlinganiselo wokutshintshwa komhlaba kunye nobunzulu obuchazwe apha ngasentla unika ukumelana okuphezulu kwempembelelo.
