Phau Ntawv Qhia Qhov Kawg rau IBO Anchors: Cov txiaj ntsig, Cov Lus Qhia, thiab Daim Ntawv Thov
Nqe 1: IBO Anchor yog dab tsi?
IBsawv cev rau Injections-Bohr-Anker (German rau Txhaj Txhaum Txhaum Cai). Nws yog ib qho kev ua haujlwm siab -kev ua haujlwm anchoring uas ua ke nrog kev drilling, grouting, thiab anchoring rau hauv ib qho kev ua haujlwm.
Tsis zoo li ib txwm thauj tog rau nkoj uas yuav tsum tau ua ntej -drilled qhov thiab casing hauv cov av xoob, IBO thauj tog rau nkoj siv lubhollow steel barraws li ob qho tib si laum pas nrig thiab qhov kawg qhov cuab lub zog.
Cov ntsiab lus tseem ceeb:
Hollow Bar:Lub raj steel nrog txuas txuas sab nraud.
Sacrificial Drill Bit:Txuas nrog rau pem hauv ntej, xaiv raws li geological tej yam kev mob (xws li, Tungsten Carbide rau pob zeb, Steel Hla me ntsis rau xoob av).
Coupler:Siv los txuas ntau qhov tuav kom ncav cuag qhov tob uas xav tau.
Plate thiab txiv ntseej:Siv los hloov lub load rau saum npoo / qauv.
Tshooj 2. Yuav Ua Li Cas IBO System Ua Haujlwm: Tus Txheej Txheem "3-hauv-1".
Lub hauv paus yog vim li cas rau qhov muaj koob meej ntawm IBO thauj tog rau nkoj yog nws txoj kev txhim kho yooj yim, feem ntau hu ua3-hauv-1 txoj kev:
Drilling:Lub hollow bar, nruab nrog lub laum me ntsis, yog tsav mus rau hauv av los ntawm ib tug teb -percussion laum rig. Thaum lub sij hawm drilling, qhov nruab nrab ntawm cov dej ntws tawm (dej los yog cov cement nyias) yog nqus los ntawm qhov chaw hollow kom tshem tawm cov txiav.
Grouting:Thaum lub hom phiaj qhov tob yog mus txog, ib tug thicker cement grout yog txhaj los ntawm lub hollow bar. Lub grout tshwm sim los ntawm lub qhov nyob rau hauv lub laum me ntsis, sau lub annulus los ntawm lub hauv qab mus.
Anchoring:Lub grout permeates cov av ib puag ncig los yog pob zeb, tsim kom muaj kev sib raug zoo. Thaum kho, lub hollow bar ua raws li tus tswv cuab nruj, muab kev txhawb zog tam sim.
Ntu 3: Cov Ntawv Thov Tseem Ceeb
Kev hloov pauv ntawm IBO thauj tog rau nkoj ua rau nws yog ib qho tseem ceeb hauv ntau yam kev lag luam hauv pej xeem:
Tunneling:Siv rauTube Umbrellas (Forepoling)los muab kev txhawb nqa ua ntej- ua ntej kev khawb thiab rau pob zeb radial bolting.
Slope Stabilization:Zoo tagnrho rauAv Nailingnyob rau hauv cov cheeb tsam uas cov av tej yam kev mob yog unpredictable los yog nws yuav vau.
Foundations:Siv raws liMicropileslos txhawb kev tsim lub hauv paus lossis los txhawb cov qauv uas twb muaj lawm uas muaj kev sib haum xeeb.
Mining:Txhim kho cov phab ntsa siab thiab ruaj khov rau txoj kev hauv av.
Kev them nyiaj yug Excavation:Muab khi- nraub qaum anchors rau khaws cov phab ntsa thiab daim ntawv pawg bulkheads.

Vim li cas cov engineers yuav tsum xaiv IBO thauj tog rau nkoj hla cov khoom ib txwm muaj?
01
A. Tsis xav tau Casing
Nyob rau hauv "collapsing av" (xws li xuab zeb, gravel, los yog silt), qhov feem ntau qhov tsua nyob rau hauv ua ntej ib txwm thauj tog rau nkoj yuav muab tso rau. IBO anchors tshem tawm qhov kev pheej hmoo no vim tias "txoj hlua laum" nyob hauv av raws li kev txhawb nqa.
02
B. Superior Productivity
Vim hais tias drilling thiab installation tshwm sim ib txhij, IBO anchors tuaj yeem ntsia tau2-3 zaug sai duadua li cov txheej txheem ib txwm ua, txo cov nqi zog thiab cov sijhawm ua haujlwm tau zoo.
03
C. Txhim kho Bond Strength
Lub nruam xov profile ntawm hollow bar muab ib qho zoo heev mechanical daim ntawv cog lus nrog lub grout. Tsis tas li ntawd, lub siab- cov txheej txheem grouting thaum lub sij hawm drilling pab compact lub borehole phab ntsa thiab txhim kho kev sib txhuam ntawm daim tawv nqaij.
04
D. Versatility nyob rau hauv Tight Spaces
IBO cov tshuab tuaj yeem ntsia tau siv cov cuab yeej me me, cov xov tooj ntawm tes, ua rau lawv zoo tagnrho rau tunneling, hauv qab daus retrofitting, thiab cov chaw uas muaj cov nyiaj siv ua haujlwm tsawg.
FAQ
Q: Cov qauv thoob ntiaj teb dab tsi ua koj tus kheej -drilling bolts ua raws li?
A: Peb cov tshuab SDA (xws li R-xov thiab T- xov) yog tsim nyob rau hauv nruj raws li ISO 10208 thiab ASTM cov qauv. Peb siv siab -lub zog seamless steel tubing kom ntseeg tau tias muaj zog tensile zoo dua thiab muaj zog txaus rau kev thov cov mining thiab tunneling tej yaam num.
Q: Vim li cas SDA bolts ua haujlwm zoo dua li cov pob zeb pob zeb hauv av tawg?
A: Cov bolts ib txwm xav tau ua ntej -drilled qhov uas feem ntau tawg hauv av xoob. Lub SDA system sib txuas cov drilling, grouting, thiab anchoring rau hauv ib qho kev ua haujlwm. Qhov no tshem tawm qhov xav tau ntawm cov kav dej thiab tiv thaiv lub qhov borehole, txuag txog li 50% ntawm lub sijhawm installation.
Q: Koj cov txiv ntseej kheej kheej ua li cas tuav cov pob zeb tsis sib xws?
A: Peb precision-engineered kheej kheej txiv ntseej (dome ceev), thaum ua ke nrog domed daim hlau, tso cai rau 7 mus rau 10 degrees ntawm angular them. Qhov no ua kom ntseeg tau tias lub ntsia liaj qhov rooj tswj xyuas qhov ruaj ntseg, qhov sib npaug ntawm cov khoom xa tawm txawm tias lub ntsej muag lub ntsej muag tsis sib xws lossis tsis sib xws.
