Notched Prestressed Hlau Hlau

Indented prestressed steel hlau yog ib qho cuab yeej tseem ceeb hauv kev tsim vaj tsev engineering siv los txhim kho qhov tawg tsis kam thiab thauj khoom -cov kabmob muaj peev xwm ntawm cov pob zeb ua vaj tse. Hlau hlau nrog cov qauv tsis tu ncua indentations yog prestressed ua ntej pob zeb pouring, siv kev sib txhuam ntawm cov hlau thiab pob zeb kom hloov prestress thiab txhim kho cov txheej txheem kev nyuaj siab.

Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, indented nyob ntawm tej feem ntau yog ua los ntawm siab - carbon steel los yog alloy steel nrog ib tug tensile lub zog ntawm tsis tsawg tshaj li 1570 MPa thiab ib tug elongation ntau tshaj 4%. Qhov tob indentation yog tswj los ntawm 0.1 thiab 0.3 hli, thiab qhov sib nrug ntawm cov indentations nyob ib sab yog 3-5 npaug ntawm txoj kab uas hla. Thaum lub sijhawm ua haujlwm, cov cuab yeej tshwj xeeb dov yog siv los ua tib lub sijhawm nias cov ntaub ntawv thaum lub caij txias -txoj kev kos duab kom ntseeg tau tias zoo ib yam thiab tsis tu ncua. Cov xov hlau tiav lawm yuav tsum tau kho kom ruaj khov kom tshem tawm cov kev ntxhov siab seem thiab tau coated nrog cov yeeb yaj kiab los tiv thaiv xeb.

Hauv kev siv cov tswv yim, nws feem ntau pom nyob rau hauv cov xwm txheej xws li lub thawv girders rau ntev -span txuas hniav, hloov cov plag tsev ntawm siab -nce vaj tse, thiab circumferential reinforcement ntawm loj cia tso tsheb hlau luam. Nyob rau hauv cov ntaub ntawv kawm ntawm kev tsim kho ntawm tus choj Yangtze River, pab neeg tsim kho siv 7 hli txoj kab uas hla indented steel hlau bundles, txhua pob muaj 12 steel hlau, nrog rau tag nrho cov nro ntawm 2200 kN. Thaum lub sij hawm kev teeb tsa, kev saib xyuas tau raug coj los xyuas kom meej tias lub vojvoog ntawm curvature ntawm cov hlau xaim tsis pub tsawg dua 3 meters kom tsis txhob muaj kev ntxhov siab hauv cheeb tsam. Cov txheej txheem thauj tog rau nkoj siv cov npoo- hom thauj tog rau nkoj, ua ke nrog tshwj xeeb hydraulic jacks rau theem tensioning, tswj kev ntxhov siab sib txawv hauv ± 5%.
