JCDRILLnws tus kheej drilling thauj tog rau nkoj yog ib qho kev daws teeb meem rau cov av nyuaj thiab pob zeb.Lub kaw lus tso cai rau drilling thiab grouting hauv ib qho kev ua haujlwm, ua kom txuag tau ntau hauv chaw ua haujlwm thiab lub sijhawm ua haujlwm.

Nyob rau hauv ib tug tej yam, tensile zog nce nyob rau hauv feem rau hardness.Rau couplers thiab txiv ntseej, nws yog ib qho tseem ceeb kom paub tseeb tias lub peev xwm haum ncav cuag lub peev xwm.Los ntawm ntau pua qhov kev sim ntsuas, ib qho qauv kuaj tau teeb tsa uas yog HRC 20 - 30 rau ob qho tib si couplers thiab txiv ntseej.

JCDRILLDrilling hollow bar yog T xov bar, uas tuaj yeem txuas zoo kawg nkaus rau ROPE xov (rau ISO10208 & ISO 1720).T-ROPE xov hollow bar muaj qhov zoo hauv qab no:

1. 45 degree kaum sab xis T xov tsim ua rau thaj tsam zoo ntawm cov xov loj thiab ua tiav cov ntawv cog lus zoo rau pob zeb.

2. 45 degree kaum sab xis T xov tsim ua rau cov kab nrib pleb dav ntawm qhov siab tshaj plaws load nyob hauv qab 0.1 hli.

3. 45 degree lub kaum sab xis T xov tsim loj txhim kho kev sib koom ua ke ntawm T-TROPE xov hollow bar nrog txiv ntseej thiab coupler.

4. T-TROPE xov tuaj yeem txuas tau zoo rau cov xov ROPE, zoo li R32, R38 thiab R51 (rau ISO 10208 thiab ISO 1720) ntawm qhov chaw ua haujlwm.
