Kupfupisa nezve mashandisirwo e Φ400mm Yakazara Inoyangarara Dicharge Hoses munzvimbo yechitsuwa-tunnel yekuvaka yeHong Kong-Zhuhai-Macao Bridge Project.

Iyo Φ400mmhose inoyangarara inoyererayakagadzirwa uye kugadzirwa neCDSR yakanyatsogadzirirwa kuti "Jielong" Dredger ishande munzvimbo yekuvaka yeHong Kong-Zhuhai-Macao Bridge Project muZhujiang estuary.Chinodiwa chikuru chekugadzira hose kuenderana nemamiriro ekushanda akaomarara semhepo inorema nemasaisai, uye yakanyanya kuoma nharaunda yenzira yemvura.

Mushure mehoses inoyangararaakasvika panzvimbo yebasa yeNansha muGuangzhou, zvakatora mazuva mashanu kuti avabatanidze, uye ipapo tambo yepombi yakadhonzwa kunzvimbo yebasa yeHong Kong-Zhuhai-Macao Bridge Project kuti iendeswe.Muedzo we "Jielong" Dredger wakaitwa kubva munaSeptember 21 kusvika ku23, uye basa rekuchera rakatanga musi waOctober 20. The hose tambo yakasangana nemamiriro akasiyana-siyana egungwa.Mushandisi anofunga The CDSRhoses inoyangararainosangana zvizere nezvinodiwa zvekugadzira uye kunyatsoenderana nemamiriro egungwa munzvimbo yebasa yeHong Kong-Zhuhai-Macao Bridge Project.Kuita kweiyo inoyangarara yekuburitsa hose tambo inoshandiswa mukuvaka dredging zvakare inopindirana nekuongororwa kwe "Avaluation Report yeKutsigira Hose Type Selection Scheme".Ruzivo rukuru rwekuongorora kwemushandisi ndeichi:

1. Thehose inoyangararairi nyore kuisa, majoini e-hose-to-hose akavharwa zvakanaka, uye hapana kubuda kwakawanikwa panguva yekushandiswa, kusangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza munzvimbo yekuvaka.

2. Kuitwa kwemakumbo ekusimudza pamagumo etambo yehose inosangana nezvinodiwa zvekugadzira.Mushure mekunge anchor yabatanidzwa, makumbo ekusimudza akasangana nekukanganisa kwemhepo inoenderera uye masaisai emhepo.Hapana deformation kana kuputsika kwakawanikwa pamakumbo ekusimudza.

3. The mechanical properties of thehoses inoyangararadzakanaka kwazvo, kunyanya zvichireva kusimba nekukotama kwepombi mumhepo ine simba nemasaisai, uye kuita kwekuzvidzora mushure mekupeta kana kumonyoroka.

4. The buoyancy of thehose inoyangararainosangana nezvinodiwa zvekugadzira, uye mamiriro ekuyangarara emapombi akagadzikana uye zvakanaka.
