Ụlọ ọrụ Oghere Steel Space Frame 90m Span Coal Yard Project
Nwụnye ihe owuwu Frame Oghere:
Nke a oru ngo bụ arched oghere etiti / elu bụ 49 mita / ngụkọta ogologo 633 mita / ngụkọta span 76.3 mita.
Ihe oru ngo a na-anakwere etiti oghere nchara, ụdị nkwado bụ nkwado ụdọ ala, nkwonkwo bọọlụ bolt, yana grid ụgbọ elu pyramid nwere okpukpu abụọ.A na-akwado etiti grid na ogidi ndị dị n'akụkụ abụọ, na nkwado ndị a na-ejikọta na isi kọlụm nke ogidi ndị ahụ.Igwe ọkụ eletrik na wires ejiri maka ịgbado ọkụ kwesịrị izute ihe ndị dị mkpa nke ụkpụrụ mba dị ugbu a.Ịgbado ọkụ n'etiti Q235B steels na-anabata E43 usoro electrodes, na ịgbado ọkụ n'etiti Q345B steels nakweere E50 usoro electrodes.
A na-agbakọ ma hazie etiti oghere igwe site na ngwanrọ MST2020.
Na mgbakwunye na imezu ihe achọrọ nke koodu ihe onwunwe nke mba, ígwè eji arụ ọrụ a kwesịkwara imezu ihe ndị a:
