Kugwiritsa ntchito milu yachitsulo yopangidwa ndi U-yotentha yozungulira nyumba zazikulu

Milu yooneka ngati U ndi chida chatsopano chaukadaulo chomwe changotulutsidwa kumene kuchokera ku Netherlands, Southeast Asia ndi malo ena. Tsopano amagwiritsidwa ntchito kwambiri mumtsinje wonse wa Pearl River Delta ndi Yangtze River Delta. Malo ogwiritsira ntchito: mitsinje ikuluikulu, malo osungiramo nyanja, malamulo a mitsinje yapakati, kumanga dzenje la maziko, Misewu, milatho, ntchito zamatauni ndi kumanganso malo achitatu
Chidziwitso pazabwino zogwiritsira ntchito milu yooneka ngati U-mapepala:
1. Chigawo chachikulu chosungira. U-woboola pakati prestressed konkire pepala mulu umodzi kusunga gawo kutalika kufika mamita 1, amene ali kutali ndi miyambo pepala milu ndi wamba precast mulu mitundu.
2. Mawonekedwe a mawonekedwe opanikizika apakati ndi abwino kwambiri. Mapangidwe opangidwa ndi mawonekedwe a U-mawonekedwe amatengedwa kuti awonjezere kutalika kwa magawo ndi mphindi ya inertia, potero kumapangitsa kuti pakhale kupsinjika kwa kapangidwe kake.
3. Phindu lazachuma ndi lodziwikiratu. Mapangidwe opangidwa ndi U amatengedwa, omwe amachepetsa kwambiri kuchuluka kwa konkriti yomwe imagwiritsidwa ntchito mumtundu wa muluwu poyerekeza ndi milu wamba yamapepala pamtunda womwewo. Nthawi yomweyo, mulu wa pepala lopangidwa ndi U umatenga kapangidwe kake kokhazikika, komwe kumachepetsa kwambiri kupsinjika ndi kulimbikitsa zofunikira pokwaniritsa zofunikira zolimbikitsira. Kuchuluka kwa kulimbikitsidwa muzopangidwe kumawonjezeka ndipo mtengo umachepetsedwa. Pa nthawi yomweyo, nthaka kusunga m'lifupi mulu uwu mtundu umodzi mulu kufika 1 mita, amene ali kutali ndi wamba mulu mtundu. Kutengera mawonekedwe omwe ali pamwambawa, mtengo wamilu yopangidwa ndi konkriti yokhala ndi mawonekedwe a U ndi pafupifupi 30% yotsika kuposa milu yachikhalidwe wamba, yomwe ili ndi phindu pazachuma.
4. Mtundu wa chitsanzo. Mitundu ya milu ya konkire yokhala ndi mawonekedwe a U-prestressed prestressed sheets ikhoza kusankhidwa mosinthika kuti ikwaniritse zosowa za polojekiti potengera kutalika kwa magawo osiyanasiyana, mafomu olimbikitsira, kuchuluka kowonjezera komanso kutalika kwa milu malinga ndi zofunikira zamakina amtundu wa muluwo. Kukwanilitsa kukhathamiritsa kwa mapangidwe a magawo osiyanasiyana ndikukulitsa phindu pazachuma.
5. Nthawi yomanga ndi yochepa. U-woboola pakati prestressed konkire pepala milu kutengera fakitale prefabricated mode, ndi malo yomanga ndi umakanidwe kumanga pepala mulu khoma, amene kwambiri kufupikitsa nthawi yomanga poyerekeza ndi njira zachikhalidwe.
6. Ukadaulo womanga, mawonekedwe osiyanasiyana ogwiritsira ntchito geological, komanso gawo lokongola pamtanda pambuyo pa kupanga milu
