Chipinda cholumikizira cha portal ndi chitoliro chokhazikika cha chitsulo chopangidwa ndi chimango cha portal, chothandizira chopingasa, ndodo yolumikizira, bolodi la chitoliro chopingasa kapena chimango chopingasa, mkono wokhoma, ndi zina zotero, kenako chokhala ndi ndodo yolimbitsa yopingasa, cholumikizira chopingasa, ndodo yotambasula, ndodo yotsekera, bulaketi ndi maziko, ndipo cholumikizidwa ndi kapangidwe kake ka nyumbayo ndi zida zolumikizira khoma. Chitoliro cha chitsulo cha portal chingagwiritsidwe ntchito osati ngati chitoliro chakunja chokha, komanso ngati chitoliro chamkati kapena chitoliro chonse.

cholinga

1. Amagwiritsidwa ntchito pothandizira denga m'mapangidwe a nyumba, maholo, milatho, ma viaducts ndi ngalande kapena ngati chimango chachikulu chothandizira mapangidwe owuluka.

2. Pangani ma scaffold amkati ndi kunja kwa nyumba zazitali.

3. Pulatifomu yogwirira ntchito yosunthika yoyika magetsi, kukonza thunthu ndi ntchito zina zokongoletsa.

4. Malo ogona akanthawi, nyumba yosungiramo katundu kapena malo ogwirira ntchito angapangidwe pogwiritsa ntchito chivundikiro cha khomo ndi denga losavuta.

5. Imagwiritsidwa ntchito kukhazikitsa holo yakanthawi ndi malo oimikapo magalimoto

Chipinda cholumikizira zinthu zomangira chimakhala ndi mawonekedwe osinthasintha, mayendedwe osavuta komanso kufalikira kwamphamvu. Chifukwa chake, chimagwiritsidwa ntchito kwambiri ku China. Mu uinjiniya wa zipinda, kugwiritsa ntchito kwake kumaposa 60%. Ndi malo omwe amagwiritsidwa ntchito kwambiri komanso omwe amagwiritsidwa ntchito kwambiri pakadali pano. Komabe, mtundu uwu wa chipinda cholumikizira uli ndi chitsimikizo chochepa cha chitetezo komanso magwiridwe antchito ochepa omanga, ndipo sungakwaniritse zosowa za chitukuko cha mapulojekiti omanga.

Pali zambiri zomwe zimapangidwira komanso kukula kwa zigawo zazikulu

Pali mitundu yambiri ya ma portal scaffolds padziko lonse lapansi, kuphatikizapo ma unit apadziko lonse lapansi ndi ma unit aku Britain oyezera. Mwachitsanzo, m'lifupi mwa chimango cha portal cha 1219 mu unit yaku England ndi 4 '(1219mm) ndipo kutalika ndi 6′ (1930mm), ndipo m'lifupi mwa chimango cha portal cha 1219 mu unit yapadziko lonse lapansi ndi 1200 mm ndipo kutalika ndi 1900 mm. M'lifupi mwa gantry ya makampani akunja scaffold makamaka muli 900, 914, 1200 ndi 1219 mm. Pali miyeso yambiri ya kutalika kwa gantry, kupanga seti ya dongosolo.

Mafotokozedwe a zinthu zomwe opanga angapo ku China amachita ku China nawonso ndi osagwirizana kwambiri. Ena amatsanzira mafotokozedwe azinthu zakunja, ndipo mayunitsi ena ofufuza akunyumba amapanga dongosolo lokha. Ena amagwiritsa ntchito kukula kwa Britain ndipo ena amagwiritsa ntchito kukula kwa mayunitsi apadziko lonse lapansi. Mwachitsanzo, m'lifupi mwa gantry ndi 1219mm mu dongosolo la Chingerezi, 1200mm mu dongosolo la mayunitsi apadziko lonse lapansi, ndipo mtunda wa chimango ndi 1829mm ndi 1830mm motsatana. Chifukwa cha miyeso yosiyanasiyana iyi, gantry singagwiritsidwe ntchito wina ndi mnzake. Mwachitsanzo, pali mafotokozedwe ndi makulidwe opitilira asanu ndi atatu a gantry, ndipo palinso kukula kwa mipata pakati pa mapini olumikizira, zomwe zimapangitsa kuti pakhale mafotokozedwe ambiri ndi mitundu yosiyanasiyana ya ma cross diagonal bracing.

Chifukwa cha kukula kwakukulu kwa makampani, tikufuna makampani amphamvu ngati ife kuti tikwaniritse zofunikira zosiyanasiyana za makasitomala. Takulandirani kuti mufunse, chonde titumizireni imelo kuti mudziwe zambiri.
