Chile tab tom tsim lub Chacao Suspension Choj, ib txoj haujlwm tseem ceeb uas yuav dhau los ua tus choj ntev tshaj plaws hauv South America, hla 2,750 meters. Kev sib txuas ntawm Chiloé Island mus rau thaj av loj, tus choj ntsib kev nyuaj ib puag ncig: nws nyob tsuas yog 80 km ntawm thaj chaw loj seismic txhaum cai, qhov twg av qeeg keeb kwm tau mus txog qhov ntau ntawm 9.5 hauv 1960 thiab 8.8 hauv 2010, thiab hla cov cua turbulent nrog cua ceev / tshaj 240 km.
Tus choj tag nrho cov nqi tsim kho yog kwv yees li ntawm $ 700 lab. Thaum ua tiav, nws yuav hloov cov kev pabcuam ferry, txo lub sijhawm hla ntawm 30-45 feeb mus rau 3 feeb xwb, txhawb kev loj hlob ntawm kev lag luam hauv cheeb tsam thiab kev lag luam.
Steel Structures rau Seismic thiab Cua Resistance
Lub Chacao Choj tso siab rau siab - lub zog ntawm cov qauv hlau thiab corrosion- cov hlau tiv taus kom tiv taus kev ua seismic thiab hnyav marine tej yam kev mob. Lub ntsiab spans ntawm 1,055 meters thiab 1,100 meters tau txais kev txhawb los ntawm peb qhob qhob pylons, nrog lub hauv paus pylon sawv 175 meters siab ntawm Remolinos reef. Txhawm rau txhim kho seismic resilience, cov pylons suav nrog cov hlau -cov tub ntxhais siv zog thiab 70-mm-thick steel cladding, sib txuas cov hlau siab ductility nrog yooj yim nqus los ntawm ob qho tib si av qeeg thiab muaj zog tidal tam sim no.
Lub thawv orthotropic steel girders tsim lub 24-meter- dav choj lawj yog tsim los ntawm 20,700 tons ntawm siab- lub zog steel qauv, featuring longitudinal trusses thiab transverse beams optimize load faib thiab tswj rigidity nyob rau hauv lub tsheb hnyav tsheb. Tus qauv tsim kom txo qis lub lawj qhov hnyav yam tsis muaj kev cuam tshuam cov qauv ntawm lub zog, qhov tseem ceeb hauv thaj av av qeeg.
Galvanized Steel Hlau thiab Suspension Cables
Suspension cables siv galvanized steel hlau, muab lub zog zoo- rau- qhov hnyav piv, kom ntseeg tau tias lub ntsiab spans nyob ruaj khov nyob rau hauv dynamic loads thaum tiv thaiv corrosion los ntawm marine ib puag ncig. Cov hlau cables ua hauj lwm nyob rau hauv tandem nrog lub lawj lub reinforced steel lub thawv girders kom xa mus ntev - lub sij hawm ua tau zoo thiab durability.
Advanced Steel Engineering
Txhua feem ntawm Chacao Choj-los ntawm seismic- cov pylons tiv taus thiab cov hlau lawj mus rau galvanized suspension cables- yog tsim los rau kev ua haujlwm ntev thiab kev nyab xeeb. Seismic-cov qauv hlau tiv taus, corrosion-cov hlau tsis muaj zog, thiab siab- cov ntaub ntawv steel ua tau zoo tso cai rau tus choj kom tiv taus 100 xyoo ntawm kev ua haujlwm, av qeeg tsis tu ncua, thiab cua daj cua dub tshaj 240 km / h. Kev ua tib zoo sib xyaw ua ke ntawm cov qauv steel, steel reinforcement, thiab orthotropic steel decks ua kom pom kev ua haujlwm zoo thaum tswj kev tsim kho thiab cov khoom siv ntev.
Chacao Choj ua piv txwv lub luag haujlwm tseem ceeb ntawm cov hlau hauv cov txheej txheem niaj hnub no. Steel kev sib xyaw ua ke ntawm lub zog, ductility, thiab corrosion kuj ua rau cov engineers kom ua tiav cov qauv tsim, hloov cov chaw nyuaj rau hauv kev nyab xeeb, txhim khu kev qha kev thauj mus los rau cov zej zog thiab kev lag luam.
