Lub nroog qhov kev ua haujlwm ib txwm nyob ntawm lub qhov dej-tsim lub qhov dej, tshwj xeeb tshaj yog thaum lub caij los nag, thaum lub kaw lus ua haujlwm ncaj qha cuam tshuam rau lub nroog kev nyab xeeb thiab kev ruaj ntseg. Cov kav dej hlau, uas yog cov khoom siv zoo - cov yeeb nkab zoo, ua lub luag haujlwm tseem ceeb hauv cov kav dej hauv nroog, muab "lub kaus tiv thaiv" muaj zog rau lub nroog.
NO.1 A "Tus Saib Xyuas Kev Tiv Thaiv" hauv nag xob nag cua
Cov dej hauv nroog dais siab heev thaum los nag hnyav. Cov kav dej zoo tib yam tuaj yeem tawg nyob rau hauv qhov kev nce siab ntawm cov dej siab, ua rau lub cev tsis ua haujlwm. Cov kav dej hlau, nrog rau lawv cov kev ua haujlwm siab dua, ua lub hauv paus tseem ceeb ntawm cov kav dej. Lawv tuaj yeem tiv taus cov dej nrawm nrawm thaum los nag hnyav, ua kom muaj kev ua haujlwm zoo ntawm cov kav dej thiab tiv thaiv dej los yog dej nyab los ntawm cov yeeb nkab ruptures.
Tsis zoo li cov kav hlau cam khwb cia zoo tib yam, cov kav hlau kav hlau tau txais kev kho tus neeg sawv cev spheroidizing, uas, thaum tswj kev tiv thaiv corrosion ntawm cam khwb cia hlau, kuj muab cov cuab yeej zoo dua qub thiab hnav tsis kam. Qhov kev sib xyaw ua ke ntawm rigidity thiab yooj yooj yim tso cai rau lawv hloov mus rau qhov tsis sib xws hauv av thiab tswj kav kev ncaj ncees txawm tias thaum cov av hloov.
NO.2 Lub Corrosion-Resistant "Long-Lusing General"
Cov dej zoo hauv cov kav dej hauv nroog yog qhov nyuaj, muaj ntau yam tshuaj thiab cov kab mob, ua rau cov khoom siv yeeb nkab zoo ib yam ua rau corrosion thiab laus. Cov kav dej hlau, nrog lawv cov phab ntsa sab hauv lined nrog siab - alumina cement mortar rau kev tiv thaiv corrosion, muaj cov kua qaub thiab alkali tiv thaiv zoo, tiv taus qhov yaig ntawm acidic thiab alkaline Cheebtsam hauv cov dej phwj tuaj.
Sab nrauv phab ntsa yog coated nrog zinc thiab pleev xim rau xim liab epoxy (cov kav dej feem ntau yog xim liab, thaum cov kav dej yog xim dub), ua kom muaj kev tiv thaiv ob. Qhov kev tiv thaiv zoo no tso cai rau nws nyob rau ntau tshaj 50 xyoo nyob rau hauv qhov chaw ntub dej thiab corrosive, deb tshaj li lub neej ntawm lwm cov khoom siv yeeb nkab.
NO.3 "Smooth Traffic Flow Expert" rau High -Tuam Tshoj Cheeb Tsam
Hauv cov cheeb tsam uas muaj nag los nag, loj - txoj kab uas hla ductile hlau kav tau dhau los ua qhov tseem ceeb rau kev txhim kho cov kua dej. Piv txwv li, nyob rau hauv lub renovation project ntawm Xiaomishan Road nyob rau hauv Zhenjiang, Jiangsu xeev, ductile hlau kav kav nrog ib tug puab txoj kab uas hla ntawm 2.4 meters thiab ib tug tib yeeb nkab uas hnyav kwv yees li 14 tons tau siv, nrog ib tug tag nrho nteg ntev ntawm ze li ntawm 300 meters. Cov kav dej no muaj lub neej ntev tshaj li 50 xyoo, tuaj yeem tiv taus siab - nrawm nrawm cuam tshuam, thiab txhim kho cov dej ntws hauv cheeb tsam. Piv nrog rau cov kav dej ib txwm siv, cov kav hlau kav hlau muaj cov phab ntsa du, kev ua haujlwm zoo dua hydraulic, thiab cov dej ntws loj dua rau tib qhov kev qhia tshwj xeeb, ua kom yooj yim hauv nroog dej nyab.
Lub caij los nag yog ib qho kev sim ntawm nroog infrastructure. Cov kav dej hlau, nrog rau lawv qhov zoo ntawm lub zog siab, kev tiv thaiv corrosion, kev sib khi zoo, thiab kev tsim kho yooj yim, tau dhau los ua "cov pob txha" ntawm cov kav dej hauv nroog.
Raws li ib tug siab - zoo ductile hlau yeeb nkab hom, Jintai Hongye boasts zoo heev cov khoom zoo, nruj txheej txheem ntau lawm, thiab ib tug zoo ua lag luam lub koob npe nrov, muab koj nrog txhim khu kev qha cov khoom thiab tom qab- kev muag khoom.
NO.1
Cov khoom zoo thiab tus nqi tswj, txhim khu kev qha khoom lav
NO.2
Kev tswj hwm lub neej ntawm cov khoom thiab kev ua tiav tom qab - kev muag khoom.
NO.3
Kev tswj hwm lub neej ntawm cov khoom thiab kev ua tiav tom qab - kev muag khoom.
