Hydraulic Expansion Anchor
Water Swelling Friction Bolt yog tsim los ntawm lub zog siab welded raj folded nws tus kheej thiab welded los muab khi rau ntawm ob qho kawg ntawm bolt.
Txoj haujlwm ua haujlwm:
Thaum lub bolt siv rau hauv lub qhov, lub hav txwv yeem nrog lub qhov yog txuas nrog lub chuck ntawm lub twj tso kua dej siab.Pib lub twj tso kua mis thiab txhaj cov dej rau hauv lub raj, lub folding phab ntsa ntawm bolt yog yuam kom nthuav dav.Thaum lub twj tso kua mis ncav cuag tus txheej txheem siab, cov phab ntsa ntawm lub ntsia liaj qhov rooj tuav mus rau lub strata thiab tsim kom muaj kev sib txhuam loj loj los txhawb nqa. Yog li, kev ruaj ntseg thiab ruaj khov kev txhawb nqa yog tsim.
Daim ntawv thov tseem ceeb ntawm Hydraulic Expansion Anchor yog ib ntus pob zeb txhim kho hauv Mining thiab Tunneling.Kev sib txuas ua ke ntawm kev sib txhuam bolt thiab pob zeb loj yog tshwm sim los ntawm kev kaw thiab kev sib txhuam hloov ntawm phab ntsa borehole thiab pob zeb ntsia liaj qhov rooj uas nthuav dav los ntawm hydraulic siab.
Fields of Application:
Systematic reinforcement ntawm underground excavations
Kev tswj hauv av ib ntus
Lub ntsiab zoo:
Tam sim no tag nrho cov kabmob muaj peev xwm hla tag nrho cov ntsia liaj qhov rooj ntev
Tsawg rhiab heev tiv thaiv kev vibrations los ntawm kev ua haujlwm blasting
Muaj peev xwm tswj tau lub peev xwm thauj khoom txawm tias thaum muaj deformations
Kev nyab xeeb thiab yooj yim installation
Tsis muaj cov khoom siv hauv tsev ntxiv rau kev teeb tsa
Flexibility nyob rau hauv cov ntaub ntawv ntawm txawv los yog txawv borehole diameters
Kev kuaj xyuas zoo thaum txhua qhov kev teeb tsa
