Anchor bolt
Thauj tog rau nkoj ntsia liaj qhov rooj txhais tau hais tias ib tug pas nrig uas hloov cov qauv los yog geotechnical load rau lub pob zeb ruaj khov
formations, nws muaj pas nrig, xyaum me ntsis, coupling, phaj, grouting stopper thiab txiv ntseej.Nws tau ua
dav siv nyob rau hauv tunnling, mining, txoj kab nqes stabilization, tunneldiseases kho thiab ru tsev txhawb
ntawm undergroundworks.Nws yog rau xoob av (av nplaum, xuab zeb friable thiab lwm yam) Hollow thauj tog rau nkoj pas nrig yog ua los ntawm
seamless raj nrog lub zog siab.
Feature ntawm hollow grounting thauj tog rau nkoj bolt
• Tshwj xeeb yog tsim rau cov av nyuaj.
• Tus nqi siab ntawm kev txhim kho txij li thaum drilling, tso thiab grouting tuaj yeem ua tiav hauv ib qho haujlwm.
• Cov txheej txheem drilling tus kheej tshem tawm qhov yuav tsum tau ua rau lub qhov borehole.
• Txhim kho nrog ib txhij drilling thiab grouting ua tau.
• Ib qho yooj yim installation nyob rau hauv tag nrho cov lus qhia, kuj upwards.
• Tsim nyog rau kev ua hauj lwm hauv qhov chaw tsawg, qhov siab thiab nyob rau hauv qhov chaw ntawm kev nkag tau yooj yim.
• Yooj yim post grouting system.• Kub-dipped galvanizing rau kev tiv thaiv corrosion
Kev siv hauv Tunneling & Av Engineering
• Radial bolting
• Kev ruaj ntseg ntawm txoj kab nqes
• Forepoling
• Micro txhaj pawg
• Lub ntsej muag stabilization
• Kev them nyiaj yug thauj tog rau nkoj ib ntus
• Kev npaj Portal
