Kushandiswa kwesimbi inopisa-yakaputirwa U-yakagadzirwa nesimbi mirwi yezvivako zvakakura

U-akaumbwa pepa piles chigadzirwa chitsva chetekinoroji chichangobva kuunzwa kubva kuNetherlands, Southeast Asia nedzimwe nzvimbo.Iye zvino vari kushandiswa zvakanyanya muPearl River Delta yose uye Yangtze River Delta.Nzvimbo dzekushandisa: nzizi hombe, gungwa cofferdams, yepakati rwizi mutemo, nheyo gomba kuvaka, Migwagwa mikuru, mabhiriji, mapurojekiti ekanzuru uye yechitatu-nhanho kuvakazve wharf.
Nhanganyaya kune mabhenefiti ekushandisa kweU-akaumbwa pepa piles:
1. Chikamu chikuru chekuchengetedza.U-yakaita prestressed kongiri pepa murwi murwi mumwe chete kuchengetedza chikamu kureba kunosvika 1 mita, iri kure kure nechinyakare mapepa mirwi uye akajairwa precast mirwi mhando.
2. Muchinjikwa-chikamu chekushushikana chimiro chimiro chakanakisa.Iyo U-shaped structural cross-section dhizaini inogamuchirwa kuti iwedzere kuyambuka-chikamu kureba uye kuyambuka-chikamu nguva yeinertia, nekudaro ichivandudza kushushikana kwekuita kwechimiro.
3. Kubatsira kwehupfumi kuri pachena.Iyo U-yakaita chimiro inotambirwa, iyo inoderedza zvakanyanya huwandu hwekongiri inoshandiswa mumhando iyi yemurwi kana ichienzaniswa neyakajairwa mapepa mapairi pahurefu hwakafanana.Panguva imwecheteyo, iyo U-yakaumbwa pepa murwi inotora prestressed dhizaini dhizaini, iyo inoderedza zvakanyanya kushushikana uye kusimbaradza zvinodiwa pachimiro chekusangana nemaitiro ekusimbisa kushushikana zvinodiwa.Nhamba yekusimbisa muhutano inowedzera uye mari inoderedzwa.Panguva imwecheteyo, ivhu rinochengetedza hupamhi hweiyi murwi mhando imwe murwi inosvika 1 mita, iri kure kure neyakajairwa murwi mhando.Zvichienderana nehunhu huri pamusoro, mutengo weU-yakaita prestressed kongiri mapepa mirwi ingangoita 30% yakaderera pane iya yechinyakare mapeji mirwi, ine zvakanaka hupfumi.
4. Mhando yemhando.Mhando dzeU-yakaita prestressed kongiri pepa piles inogona kuchinjika kusarudzwa kuti isangane nezvido zvepurojekiti nekutora nzvimbo dzakasiyana dzechikamu, mafomu ekusimbisa, huwandu hwekusimbisa uye kureba kwemurwi zvinoenderana nemishini yekuita zvinodiwa zverudzi rwemurwi.Wana optimization yemuchinjika-chikamu chimiro uye wedzera mabhenefiti ehupfumi.
5. Nguva yekuvaka ipfupi.Mirwi yekongiri yakagadzirwa neU-yakaiswa prestressed inotora fekitori yakafanogadzirwa modhi, uye nzvimbo yekuvaka inogadzirwa kuti ivake murwi wemapepa, unopfupisa zvakanyanya nguva yekuvaka zvichienzaniswa nemaitiro echinyakare.
6. Tekinoroji yekuvaka, yakakura inoshanda geological range, uye yakanaka muchinjiko-chikamu mushure mekuumbwa kwemurwi
