Hauv kev tsim kho, mining, tsheb thauj mus los, thiab lwm yam kev lag luam engineering, anchoring thev naus laus zis yog lub hauv paus tseem ceeb kom ntseeg tau cov qauv kev ruaj ntseg. Ntawm cov no, wedge anchors sawv cev rau txoj kev siv tau zoo thiab yooj yim rau kev siv dav hauv ntau qhov xwm txheej. Txawm li cas los xij, qee tus yuav nug tias: Kev nyab xeeb npaum li caswedge anchors? Nws tuaj yeem hnyav npaum li cas? Hais txog lo lus nug no, kuv ntseeg hais tias lub zog ntawm wedge anchors tsis yog kiag li, thiab lawv cov load -cov kabmob muaj peev xwm cuam tshuam los ntawm ntau yam. Thaum tshawb fawb tsim thiab teeb tsa raws li cov kev qhia tshwj xeeb, lawv tuaj yeem xa cov khoom thauj zoo tshaj plaws -cov kabmob kev ua haujlwm, dhau los ua kev tiv thaiv kev ruaj ntseg rau engineering.
Lub zog ntawm wedge anchoring stems los ntawm nws qhov tshwj xeeb "tus kheej-locking wedge" mechanism.
Los ntawm kev tawm dag zog ntawm lub npoo - zoo li lub taub hau thauj tog rau nkoj thiab phab ntsa borehole, nws ruaj khov rau cov pas nrig thauj tog rau nkoj lossis cable rau cov pob zeb nyob ib puag ncig lossis substrate. Nyob rau hauv kev thauj khoom, tus qauv wedge tightens ntxiv, tsim kom muaj tus kheej -locking nyhuv qhov twg "lub tighter nws rub, lub tighter nws xauv." Qhov no zoo hloov cov loads thiab tiv thaiv slippage. Piv nrog rau cov txheej txheem anchoring ib txwm, wedge anchoring tshem tawm qhov xav tau rau kev sib txuas tshuaj lom neeg, ua kom muaj kev txhim kho sai, thiab ua kom muaj zog ntawm cov khoom siv hauv qab, ua kom muaj kev ntseeg tau zoo. Nyob rau hauv cov ntawv thov prestressed anchoring, wedge- nthuav cov thauj tog rau nkoj sab hauv hloov lub xeev kev ntxhov siab los ntawm kev nro-shear rau compression-shear, ua kom cov compressive zoo ntawm mortar thiab pob zeb loj kom ua kom muaj kev ncaj ncees zoo.
Txawm li cas los xij, lub robustness ntawm wedge anchoring tsis yog tsis muaj kev txwv.
Cov yam tseem ceeb uas cuam tshuam rau cov kab nrib pleb muaj xws li lub zog substrate, qhov tsis zoo ntawm kev tsim kho, thiab kev tsim kho kom zoo. Piv txwv li, nyob rau hauv xoob, pob zeb tawg pob zeb, siv cov pob zeb thauj tog rau nkoj nrog tsuas yog ib qho - qhov kawg thauj tog rau nkoj nthuav dav yuav ua tsis tiav vim muaj kev txwv tsis pub thauj mus los thiab kev cuam tshuam ib puag ncig. Ua kom qhov ntev ntawm cov thauj tog rau nkoj thiab sib txuas cov qhov txuas nrog cov qauv cylindrical tuaj yeem txhim kho kev ruaj ntseg. Thaum lub sij hawm tsim kho tiag tiag, drilling qhov tsis raug thiab tsis txaus lub zog ntawm lub thauj tog rau nkoj lub taub hau tuaj yeem txo qhov kev ruaj ntseg ntawm lub zog thiab txawm tias tsim kev nyab xeeb.

Txoj Kev Loj Choj Txhim Kho Txoj Haujlwm
Hauv Anbei Txoj Kev Txhim Kho Txoj Kev Txhim Kho Txoj Haujlwm, pab pawg tsim kho tau ua haujlwm patented wedge-zoo li tus kheej- xauv anchors ua ke nrog prestressed carbon fiber daim hlau, ua tiav nrog lub sij hawm ntev - cuam tshuam ntawm cov tsheb thauj khoom hnyav. Lub prestressing siv los ntawm cov npoo anchors txo cov kab nrib pleb tawg, thaum lub anchoring system tiv thaiv cov khoom loj loj rau ntawm tus choj qauv. Tom qab- kev sim kev tsim kho tau nthuav tawm qhov kev tawm tsam deb tshaj qhov tsim qauv tshwj xeeb, tsim txoj haujlwm no ua tus ncej tseem ceeb ntawm Southwest Transportation's "Great Wall of Safety."
Kev them nyiaj yug Coal Mine Tunnel
Daim ntawv thov ntawm wedge anchors hauv thee mine qhov kev txhawb nqa yog qhov zoo sib xws. Txhawm rau daws cov teeb meem ntawm cov pob zeb xoob thiab tawg ib puag ncig, kev sib xyaw ua ke ntawm cov npoo zoo thiab cov qauv cylindrical tau ua haujlwm rau kev thauj mus los. Txoj hauv kev no ua rau muaj txiaj ntsig zoo rau qhov siab tshaj plaws anchoring quab yuam los ntawm kev ua kom thaj chaw sib txuas thiab txuas ntxiv qhov ntev ntawm qhov chaw.
Wedge anchors qhia tau tshwj xeeb ntawm cov qauv kev ncaj ncees, nrog rau kev thauj khoom -cov kabmob muaj peev xwm ua tau raws li kev tsim qauv tsim kom tau raws li kev xav tau ntawm ntau hom engineering-los ntawm kev txhim kho lub tsev mus rau loj- nplai infrastructure thiab mine kev txhawb nqa. Txhawm rau ua kom lawv cov txiaj ntsig tau zoo, kev ua raws li cov qauv tsim tshwj xeeb yog qhov tseem ceeb. Qhov no suav nrog kev tswj cov substrate kom zoo, cov kev txwv tsis pub thauj mus los, thiab cov txheej txheem tsim kho kom tiv thaiv kev ua haujlwm tsis zoo los ntawm kev saib xyuas. Thaum thov kom tsim nyog, wedge anchors leverage lawv cov kev ua tau zoo thiab kev ntseeg tau los tsim kom muaj lub hauv paus ruaj ntseg rau ntau yam engineering tej yaam num.
