isakhiwo se-bollard yentsimbi yensimbi

I-bollards yokhuseleko lwensimbi

Ubunzulu obunemigangatho ye-Chedi buya kuhlangabezana neemfuno zoyilo, kwaye ubunzulu obunemigangatho baya kuhlangabezana nezi mfuno zilandelayo:
1. Xa i-cheng ingcwatywe kumhlaba owomileyo okanye amanzi angaphantsi komhlaba, ubunzulu bokungcwatywa kufuneka bube yi-1.0-1.5 amaxesha angaphantsi kwe-1.0m; Ngomaleko ongezantsi onjengentlabathi kunye nesanti, ubunzulu obungcwalisayo kuyafana, kodwa kuyacetyiswa ukuba ungabi endaweni ye-Tube engaphantsi kwe-0.5m ngaphantsi komda wetyhubhu, kwaye ububanzi bokubuyiswa kufuneka budlule Ububanzi betyhubhu yokukhusela nge-0.5-1.0m.
2. Ngamanzi anzongonzongo kunye nomhlaba othambileyo womhlaba kunye nomhlaba otyhafileyo, umda osezantsi wetyhubhu yokukhusela kufuneka ihambe nzulu kwi-suble engafezekanga; Ukuba akukho mahluko ungafikelelekiyo, kufuneka ufake i-0.5-1.0m kwigrabile enkulu kunye ne-bibeble.
3. Kwindawo yemilambo echaphazelekayo ngokugculela, umda ongezantsi wetyhubhu yokukhusela kufuneka ungenise kungaphantsi kwe-1.0m ngezantsi komgca wesikhule. Imilambo ichaphazeleke kakhulu yi-Stuur yendawo, umda osezantsi wetyhubhu yokukhusela kufuneka ingenelele ngaphantsi kwe-1.0m ngezantsi komgca wendawo yendawo.
4. Kwiindawo ezinamanzi omhlaba ovuthayo, umda osezantsi wetyhubhu yokukhusela kufuneka ungenelele ungaphantsi kwe-0.5m ukuya kumhlaba ongaphantsi komhlaba ongaphantsi komda; Kwiindawo zika-IsmmIsstrost, umda osezantsi wetyhubhu yokukhusela kufuneka ungene kwi-sublefrost yomaleko akukho ngaphantsi kwe-0.5 m. I-0.5m.
I-5. Kumhlaba owomileyo okanye xa ubunzulu bamanzi bungaphantsi kwe-3m kwaye akukho mazantsi ebuthathaka ezantsi kwesi siqithi, i-cheng ingangcwatywa ngendlela evulekileyo, kwaye umhlaba wodongwe ugcwaliswa ezantsi kwaye ujikeleze I-cheng kufuneka idityaniswe kwizinto.
I-6. Xa umzimba wesilinda ungaphantsi kwe-3m, kwaye umhlaba otshiweyo kunye nomhlaba othambileyo ezantsi kwesi siqithi awusetyenziswanga, indlela evulekileyo yokungcwaba inokusetyenziswa; Xa isando sinyibilika, isikhundla senqwelomoya, ukuqunjelwa nkqo kunye nomgangatho wonxibelelwano kufuneka ulawulwe ngokungqongqo.
7. Emanzini apho ubunzulu bamanzi bungaphezulu kwe-3m, ukhuseleko olukhuselekileyo kufuneka luncede kwiqonga lokusebenza kunye nesakhelo sesikhokelo, kunye neendlela zokwenza inkohliso, ijeyithi, njl. Njl. Kufuneka isetyenziselwe ukuntywila.
8. Umphezulu ophezulu we-cheng ufanele ube yi-2m ngaphezulu kwenqanaba lamanzi lokwakha okanye inqanaba lamanzi aphantsi komhlaba, kunye ne-0.5m ephezulu kunomhlaba wokwakha, kwaye ukuphakama kwayo kufanele ukuba kufezekiswe iimfuno zodaka emngxunyeni.
9. Kwityhubhu yokukhusela ityhubhu, ukuphambuka okuvumelekileyo kumphezulu ophezulu yi-50mm, kwaye ukuphambuka okuvunyiweyo kotyekelo yi-1%.
