Waa maxay cabbirrada cutubyada iftiinka calaamadda?

Calaamadaha taraafikadawaa calaamado iftiin oo sharci ahaan isku xiran oo tilmaamaya baabuurta iyo dadka lugeynaya inay sii socdaan ama ay istaagaan waddooyinka. Waxaa ugu horreyn loo kala saaraa nalalka calaamadaha, nalalka waddooyinka, iyo nalalka isgoyska. Nalalka calaamaduhu waa aalado muujiya calaamadaha taraafikada iyagoo adeegsanaya taxane nalalka casaanka, jaalaha ah, iyo cagaarka ah. Dalalka adduunka oo dhan waxay si cad u qeexeen oo inta badan isku mid ah qawaaniin u gaar ah macnaha midabada kala duwan ee nalalka calaamadaha. Cabbirka cutubyada nalalka calaamaduhu waxay ku diyaar yihiin saddex cabbir: 200mm, 300mm, iyo 400mm.

Dhexroorka godadka lagu rakibayo ee cutubyada iftiinka calaamadda cas iyo cagaarka ah ee ku yaal guriga calaamadda waa 200mm, 290mm, iyo 390mm, siday u kala horreeyaan, iyadoo dulqaadkiisu yahay ±2mm.

Nalalka calaamadda ee aan qaabaysnayn, dhexroorka dusha sare ee iftiinka soo saaraya ee cabbirrada 200mm, 300mm, iyo 400mm waa 185mm, 275mm, iyo 365mm, siday u kala horreeyaan, iyadoo dulqaadkoodu yahay ±2mm. Nalalka calaamadda ee leh qaabab, dhexroorka wareegyada wareegsan ee dusha sare ee iftiinka soo saaraya ee saddexda qeexitaan ee Φ200mm, Φ300mm, iyo Φ400mm waa Φ185mm, Φ275mm, iyo Φ365mm, siday u kala horreeyaan, dulqaadka cabbirkana waa ±2mm.

Waxaa jira noocyo badan oo caadi ahnalalka calaamadda casaanka iyo cagaarka ahQixiang, oo ay ku jiraan nalalka baabuurta, nalalka aan baabuurta la saarin, nalalka isgoyska dadka lugeynaya, iwm. Sida ku cad qaabka nalalka calaamadda, waxaa loo qaybin karaa nalalka tilmaamayaasha jihada, nalalka digniinta ee iftiimaya, nalalka calaamadaha isku dhafan, iwm.

Marka xigta, dhererka rakibidda ee noocyada kala duwan ee nalalka calaamadda ayaa la soo bandhigayaa.

1. Nalalka isgoyska:

Dhererku waa inuu ahaadaa ugu yaraan 3 mitir.

2. Nalalka isgoyska dadka lugeynaya:

Ku rakib dherer ahaan 2m ilaa 2.5m.

3. Nalalka laamiga:

(1) Dhererka rakibiddu waa 5.5m ilaa 7m;

(2) Marka lagu rakibo meel kor u dhaaftay, waa inaysan si weyn uga hoosayn meesha buundada laga baxo.

4. Nalalka calaamadda ee aan matoorka lahayn ee laamiga baabuurta:

(1) Dhererka rakibiddu waa 2.5m ~ 3m. Haddii tiirka nalka calaamadda gaadhiga ee aan matoorka lahayn uu yahay mid aan la saari karin, waa inuu u hoggaansamaa shuruudaha qaranka ee 7.4.2;

(2) Dhererka qaybta cantilever-ka ee nalka calaamadda gaadhiga aan matoorka lahayn waa inuu hubiyaa in nidaamka nalka calaamadda gaadhiga aan matoorka lahayn uu ku yaal meel ka sarraysa laynka bartilmaameedka gaadhiga aan matoorka lahayn.

5. Nalalka baabuurta, tilmaamayaasha jihada, nalalka digniinta ee iftiimaya iyo nalalka isgoyska:

(1) Soosaarayaasha calaamadda badbaadada taraafikada waxay isticmaali karaan dhererka ugu badan ee rakibidda cantilever-ka oo ah 5.5m ilaa 7m;

(2) Marka la isticmaalayo rakibidda tiirka, dhererku waa inaanu ka yaraan 3m;

(3) Marka lagu rakibo jirka buundada ee marin-haweedka kor u kaca, waa inaysan ka hooseyn meel bannaan oo ka baxsan buundada;

(4) Dhererka ugu badan ee qaybta cantilever-ka waa inaanu dhaafin xarunta maaraynta laynka ugu hooseeya, dhererka ugu yarna waa inaanu ka yaraan xarunta xakamaynta laynka ugu dibadda.

Qixiang waxay leedahay in ka badan toban sano oo waayo-aragnimo ah oo ku saabsan nalalka calaamadaha waxayna leedahay nalalka calaamadaha awoodda sare leh, nalalka calaamadaha awoodda hoose leh,nalalka calaamadaha dadka lugeynaya ee isku dhafan, nalalka iftiinka qoraxda, nalalka calaamadaha moobaylka, iwm. Habka ugu wanaagsan ee lagu dooran karo alaabada waa in si toos ah loogu tago soosaarayaasha jumlada ah iyada oo aan laga walwalin dammaanadaha adeegga iibka kadib. Waa lagu soo dhaweynayaa inaad timaado kormeer goobta ah.
