Kev thauj ib ntus kev thauj mus ib ntus siv thaum lub sijhawm tsim kho ntawm lub tshav dav hlau beijing Qhov nyhav ntawm ib qho 6- me nyuam ntsuas kev tsheb ciav hlau tsuas yog 90 kg, thiab txhua tus pab pawg neeg ncav cuag 1.2 km. Txoj kev taug qab yog muaj gravel gravel, thiab kev ua raws kev cai lij choj nce ntau dua li 93%, ntsib txoj kev tswj hwm kev sib haum xeeb ntawm peb-hlis.
Nyob rau hauv thaj teb ntawm kev ua liaj ua teb cov tshuab ua liaj ua teb Kev coj ntawm Changshu cov chaw ua liaj ua teb niaj hnub no qhia tau tias lub suab nrov ntawm hluav taws xob thauj khoom los ntawm cov tsheb thauj khoom no yog tsawg dua 65 decibels thaum kawg thauj nrog 500 kg. Txoj kev sib tw tiv thaiv kev tiv thaiv ob npaug-txheej tiv thaiv ntawm epoxy zinc-reimer thiab polyurethane topcoat. Nyob rau hauv lub tsev cog khoom ib puag ncig nrog cov av noo ntawm 85%, lub sijhawm tiv thaiv corrosion yog txuas ntxiv rau 5 xyoos.
Hais txog cov qauv tsim khoom, GB / t {{{0}} {}}}}} Ultrasonic qhov khuam kom pom tias yuav tsum muaj qhov sib npaug ntawm sab hauv tej yam tsis muaj ntau tshaj 2 hli, thiab kev hloov pauv head hardness yog tswj nyob rau hauv HB30. Thaum lub sij hawm installation thiab kev tsim kho, lub mm track gauge yog teem rau {} mm, thiab kab rov tav tsis pub tshaj 4 mm / 10 meters.
Hais txog cov qauv tsim khoom, GB / t 11264-2016 stipulates lub teeb qhov ntev yog}. 8 hli}. 2 hli. Ultrasonic qhov khuam txoj kab uas yuav tsum tau hais tias qhov sib npaug ntawm sab hauv tej yam tsis loj tshaj 2 hli, thiab kev hloov pauv lub taub hau tread hardness yog tswj nyob rau hauv HB30.
