Mlatho wokhala ndi chingwe cha Qinghai Kuo Ma Ri
- Mlatho wokhala ndi chingwe wa Kuo Mari uli mumsewu wa Tongren County Kuo Mari kudutsa Mtsinje wa Longwu, ndiye chigawo chakumpoto kwa msewu waukulu wa mphete. Kutalika konse ndi mamita 590, omwe amapangidwa ndi magawo awiri: kufalikira kwa kummawa ndi kumadzulo kwa Kuomari Road ndi mlatho wodutsa mtsinjewo, mlatho waukulu ndi mamita 200 kutalika. Mlatho waukulu ndi mlatho wokhala ndi nsanja imodzi yokhala ndi zingwe ziwiri zokhala ndi chingwe chokhala ndi mlatho wokhala ndi chingwe chokhala ndi pylon yooneka ngati diamondi. Njira milatho kum'mawa ndi kumadzulo ndi prestressed konkire prefabricated ang'onoang'ono bokosi milatho girder. Kampani yathu imapereka zingwe zachitsulo zopumula pang'ono komanso makina otsekera a epoxy okhala ndi chingwe cha konkire ya mlatho.Pali mapeya 14 okwana (ie 28 mitolo) ya zingwe zokhala ndi chingwe pamlatho wonse, wokhala ndi matayala okhazikika a 6 metres ndi kutalika kwa chingwe cha 222.34 metres. Chingwe chokhala ndi chingwe chimapangidwa ndi φ15.2mm epoxy coated steel strand, chomwe chimagawidwa m'magulu atatu, mtolo uliwonse wa chingwe chokhala ndi chingwe chimapangidwa ndi 31, 37 ndi 43 zitsulo zachitsulo, ndi thupi lonse la anti-corrosion. chitetezo cha HDPE chawiri-wosanjikiza, ndipo helix imakhazikika pamwamba pa zingwe zokhalamo ndikuwonjezera damping.
- Chingwe chokhala ndi chingwe chimakonzedwa mwa mawonekedwe a fan fan mu mawonekedwe a girder yayikulu ndi nsanja ya mlatho. Kumapeto kwa zovuta kumakonzedwa pamtengo waukulu, ndipo chishalo cha chingwe cha chitoliro chogawanitsa waya chimakonzedwa pansanja ya chingwe, ndipo chingwe chowongolera chimatengedwa pakhoma la nsanja mu mawonekedwe a nangula, ndi chingwe chokhazikika ndi chingwe. cholumikizidwa ndi mtengo waukulu ndikuzikika pa chipika cha nangula kunja kwa mtengo wautali.
- Mawotchi azitsulo zazitsulo zomwe zimagwiritsidwa ntchito popanga konkire yokhazikika komanso mahinjidwe achitsulo a epoxy a zingwe za mlatho amakwaniritsa zofunikira za EN10138-3, GB/T5224 ndi ASTM A416, ndipo magwiridwe antchito odana ndi dzimbiri amakwaniritsa zofunikira za ISO 14655, GB/T 2583-2010 ndi ASTM A 882/A882M-02a "Monofilament Coated Epoxy Coated Prestressed Steel Strands"; Kuchita kwa nangula kumakwaniritsa zofunikira za GB/T14370-2015 "Anchors, Clamp and Connectors for Prestressed Tendons".Chifukwa pulojekitiyi ndi chingwe chokhala ndi chingwe chokhala ndi chingwe chimodzi chokhala ndi chingwe chokhazikika, bokosi la bokosi limagwiritsa ntchito luso la zomangamanga la kuthira gawo la konkire ndi gawo lalikulu la bulaketi. Kuchuluka kwa ntchito ndi yayikulu ndipo nthawi yomangayo ndi yaying'ono, kuti zitsimikizire kuti ntchitoyo ikupita patsogolo bwino ndikumaliza pa ndandanda kapena pasadakhale, zikukonzekera kuti nkhope ziwiri zofananira zikugwira ntchito mbali zonse ziwiri za mbali yodutsa. mlatho ndi symmetrical pa nthawi yomanga mitolo iwiri ya zingwe zokhala ndi chingwe.
