NtawmGNEE RAIL, ua 60 railyog tsim los nrog tswj cov khoom muaj pes tsawg leeg thiab nruj me ntsis qhov tseeb. Txawm li cas los xij, txawm tias siab tshaj - txoj kev tsheb ciav hlau zoo yuav tsum muaj kev saib xyuas kom ua tiav ntev - lub sijhawm ua haujlwm hauv kev ua haujlwm tiag tiag.
Yuav ua li cas tswj kev tsheb ciav hlau asce 60 kom ntev kev pab cuam lub neej?
- Khaws cov kev teeb tsa kev teeb tsa ruaj khov
Kev txhim kho ruaj khov yog lub hauv paus rau kev ua haujlwm ntev.
Lub asce 60 rail qhov ntev yuav tsum phim lub fastening system thiab kev txhawb nqa qauv. Txhua qhov tsis sib haum xeeb tuaj yeem ua rau kev txav mus los, kev vibration, lossis kev thauj khoom tsis sib xws.Kev txhawb nqa qhov sib txawv yuav tsum zoo ib yam. Yog hais tias qhov sib nrug loj dhau lawm, khoov kev ntxhov siab nce ntxiv. Yog tias nws tsis sib npaug, kev ntxhov siab hauv zos yuav tshwm sim.
GNEE RAILUa kom muaj tseeb 60 lbs rail qhov ntev hauv mm, uas yuav pab txo qis kev teeb tsa thiab txhim kho kev ruaj ntseg tag nrho.
- Tswj Load thiab siv cov xwm txheej
Txoj kev tsheb ciav hlau yuav tsum tau ua haujlwm nyob rau hauv nws cov khoom tsim nyog.
Rail ASCE 60 yog tsim los rau nruab nrab - daim ntawv thov haujlwm. Yog tias siv nyob rau hauv kev thauj khoom ntau dhau lossis siab - qhov cuam tshuam ntau zaus, hnav thiab qaug zog yuav nce ntxiv.Nws yog ib qho tseem ceeb kom phim cov tsheb ciav hlau nrog cov kev ua haujlwm tiag tiag, suav nrog kev thauj khoom, ceev, thiab zaus.
Thaum sib raug zoo, txoj kev tsheb ciav hlau tuaj yeem ua haujlwm ruaj khov rau ntau xyoo yam tsis muaj teeb meem loj.
- Kev tshuaj xyuas tsis tu ncua thiab tshawb pom ntxov
Kev tshuaj xyuas tsis tu ncua pab tshawb xyuas cov teeb meem ua ntej lawv loj heev.
Xyuas lub taub hau rail rau hnav. Kev hnav ntau dhau qhia tias muaj teeb meem ntawm kev thauj khoom lossis kev sib dhos.Kuaj xyuas cov pob qij txha thiab cov tshuab fastening. Cov khoom xoob lossis puas tuaj yeem ua rau kev txav mus los thiab ua kom cov tsheb ciav hlau puas.
Cov kab nrib pleb los yog deformation yuav tsum tau kho tam sim ntawd kom tsis txhob muaj kev puas tsuaj ntxiv. Kev tshuaj xyuas niaj hnub ua kom cov teeb meem me me raug kho ua ntej lawv cuam tshuam rau tag nrho cov kab ke.
- Khaws Rail thiab Ib puag ncig huv si
Kev tswj ib puag ncig feem ntau tsis saib xyuas tab sis tseem ceeb heev.
Plua plav, khib nyiab, thiab ya raws tuaj yeem sau rau ntawm qhov chaw tsheb ciav hlau. Qhov no ua rau kom muaj kev sib txhuam thiab ua kom nrawm dua.Hauv qhov chaw corrosive, kev tiv thaiv kev tiv thaiv yuav tsum tau siv los tiv thaiv cov khoom degradation.Ua kom lub tsheb ciav hlau huv si pab tswj kev ua haujlwm du thiab txo qhov ntev - kev puas tsuaj.
- Siv cov khoom tsim nyog thiab ua tiav los ntawm Pib
Kev pabcuam lub neej pib nrog qhov zoo ntawm txoj kev tsheb ciav hlau nws tus kheej.
Cov khoom siv zoo ib yam kom ntseeg tau tias cov tsheb ciav hlau tuaj yeem tiv taus hnav thiab qaug zog. Qhov tseeb asce 60 rail qhov ntev kom ntseeg tau tias cov khoom xa tawm tau zoo.Kev ua haujlwm zoo, xws li drilling thiab txiav, yuav tsum tau tswj kom tsis txhob muaj kev ntxhov siab ntau.
