Qinghai Kuo Ma Ri tambo-yakagara zambuko
- Kuo Mari tambo-yakagara zambuko iri muTongren County Kuo Mari Road mhiri kweRwizi Longwu, ndiyo dunhu riri kuchamhembe kwemhete yechipiri trunk mugwagwa. Iyo yakazara kureba ndeye 590 metres, iyo inoumbwa nezvikamu zviviri: kumabvazuva uye kumadokero kwekuwedzera kweKuomari Road uye bhiriji mhiri kwerwizi, iro bhiriji guru rakareba 200 metres. Zambuko guru ishongwe imwe-kaviri-span space cable-yakagara zambuko ine tambo-yakagara zambuko ine pylon yakaita sedhaimani. The mazambuko nzira kumabvazuva uye kumadokero mativi vari prestressed kongiri prefabricated diki bhokisi girder mabhiriji. Kambani yedu inonyanya kupa yakaderera kuzorora prestressed simbi tambo uye epoxy coated kugara-tambo masisitimu ebhiriji kongiri.Pane hwerengedzo yezvikwata gumi nemana (kureva mabundle 28) etambo dzakavharwa netambo pazambuko rose, ine chinhanho chakajairwa chemamita matanhatu uye kureba kwetambo kwe222.34 metres. Iyo tambo-yakagara tambo yakagadzirwa ne φ15.2mm epoxy yakavharwa simbi tambo, iyo yakakamurwa kuita 3 yakatarwa, yega yega tambo-yakagara tambo inoumbwa ne31, 37 uye 43 simbi tambo tendons, uye yakazara anti-corrosion tambo muviri. yekaviri-layer HDPE kudzivirira, uye iyo helix inogadziriswa pamusoro peiyo tambo dzekugara uye yakavakirwa-mukati damping inowedzerwa.
- Iyo tambo-yakagara-tambo yakarongedzwa muchimiro chemhepo fan muchimiro chegirder huru uye shongwe yebhiriji. Mhedziso yekunetsana yakarongedzerwa padanda guru, uye tambo yetambo yepombi inotsemuka pombi yakarongedzerwa patambo yetambo, uye chigadziko chetambo chinotambirwa pamadziro eshongwe nenzira yekumisa, uye tambo-yakagara tambo iri. yakabatana nedanda guru uye yakasungirirwa pane anchor block kunze kweiyo longitudinal danda.
- Iwo emakanika zvivakwa zvesimbi tambo dzinoshandiswa mupurojekiti yeprestressed kongiri uye epoxy simbi hinges yetambo dzebhiriji zvinosangana nezvinodiwa zve EN10138-3, GB/T5224 uye ASTM A416, uye iyo anti-corrosion performance inosangana nezvinodiwa zve ISO 14655, GB/T 2583-2010 uye ASTM A 882/A882M-02a "Monofilament Coated Epoxy Coated Prestressed Steel Strands"; Kuita kweancho kunosangana nezvinodiwa zveGB/T14370-2015 "Anchors, Clamps uye Connectors for Prestressed Tendons".Nekuda kwekuti purojekiti iyi ishongwe-kaviri-tambo-yakagara tambo yetambo, girder yebhokisi inotora tekinoroji yekuvaka yekudira chikamu chekongiri nechikamu chebhureketi hombe chikamu. Huwandu hwebasa hwakakura uye nguva yekuvaka idiki, kuitira kuti ive nechokwadi chekufambira mberi kwakanaka kwekuvaka uye kupedzisa pane hurongwa kana pamberi pehurongwa, zvakarongwa kuti maviri esymmetrical anoshanda zviso pamativi ese edivi rakachinjika. zambuko ane symmetrical panguva imwe chete pakuvaka masumbu maviri etambo-akagara tambo.
