Chimiro chepasi chinofanira kuongororwa.Mutambo wakapfava unoda kureba kweanchorage kuti ishande.Ivhu rakapfava rinoguma nemasaizi akakura magomba ehukuru hwakapihwa (nekuda kwekugwedeka uye kudzokorora).
Ivhu rinofanirwa kunyatsoyerwa (kureva kuvharirwa pasi) risati raboorwa nekubhaudhi.Periodic re-scaling inogona kudikanwa paunenge uchichera.
Iyo mechanical properties yebhoti inofanira kunge yakakodzera kune mamiriro epasi, urefu hwebhoti uye bolting pattern.Dhonza bvunzo dzinofanirwa kuitwa kuti uone kwekutanga anchorage yemabhaudhi efriction.
Mahwendefa akatetepa kana asina kusimba anozokanganisa pane yakaderera bolt tension.Iyo bhaudhi inogona zvakare kubvarura ndiro panguva yekuisa kana nekurodha bhaudhi.
Gomba rinofanirwa kucheneswa uye kuongororwa kuti rive nechokwadi chekuti friction bolt inopinza zvakanaka.Kusiyana kwemadhayamita egomba (nekuda kwekusimba kwakasiyana kwedombo kana ivhu rakatsemuka zvakanyanya) rinogona kupa mutsauko mukusimba kwekusimbisa pakakwirira kwakasiyana.
Kana maburi akacherwa akapfupika saka bhaudhi rinobuda kunze kwegomba uye ndiro haizosangani nedombo.Kukuvadzwa kwebhaudhi kunozoitika kana kuedza kunoitwa kutyaira bhaudhi mberi kupfuura kureba kwegomba kunobvumira.Gomba rinofanira kudaro kudzika mainji mashoma pane kureba kwebhaudhi riri kushandiswa.
Saizi yegomba inodiwa kune friction bolt ndiyo inonyanya kukosha yekuisa.Simba rekubata rebhoti rinotsamira pakuti gomba iri duku kudarika dhayamita yebhoti.Iyo gomba yakakura inoenderana nedhayamita yebhaudhi, simba rekubata rishoma (panguva yekutanga).Maburi akakura anogona kukonzerwa nekushandisa saizi isiriyo, kusiya chibooreso chichimhanya uchipukuta buri, pasi rakapfava (zvikanganiso, gouge, etc. ) uye simbi yakakotama.
Kana saizi yegomba iri diki zvakanyanya maererano nehukuru hwekukwenya saka zvinova zvakanyanya kuoma kuisa bhaudhi.Bhaudhi rinogona kukuvadzwa kureva kinked kana kukotama kana yaiswa.Makomba asina kukura anowanzo kukonzerwa nemabhiti akasakara uye/kana masaizi asina kunaka ari kushandiswa.Kana simbi inobatanidzwa ikashandiswa nechimiso kana kuti jackleg, gomba dhayamita rinodzikira neshanduko imwe neimwe yesimbi (yakajairika tsika inoda mabhiti madiki ashandiswe sechibhorani chimwe chakadzika mugomba).Nekuderedzwa kwega kwega kwegomba dhayamita anchorage kugona kunowedzera.Integral simbi inowanzokonzera makomba akakombama uye inofanira kudziviswa pose pazvinogoneka.
Kune akajairika 5 kana 6 tsoka friction bolt, chinomira kana jackleg inotyaira bhaudhi mugomba mumasekonzi masere kusvika gumi nemashanu.Iyi nguva yekutyaira inoenderana neyakakodzera yekutanga anchorages ye stabilizer.Inokurumidza kutyaira nguva dzinofanirwa kushanda seyambiro yekuti gomba saizi yakakura zvakanyanya uye nekudaro anchorage yekutanga yebhaudhi ichave yakaderera.Nguva dzekutyaira dzakarebesa dzinoratidza masaizi madiki madiki anogona kukonzerwa nekupfeka zvishoma.
Mabhatani mabhiti anowanzo kusvika 2.5mm akakura kupfuura saizi yavo yakatemerwa.Iyo 37mm bhatani bhiti inogona kunge iri 39.5mm mudhayamita kana iri nyowani.Izvi zvakakurisa kuita 39mm friction.Mabhatani mabhiti anopfeka nekukurumidza zvakadaro, achiwedzera anchorage kugona uye kuwedzera nguva dzekutyaira.Muchinjikwa kana "X" mabhiti, kune rumwe rutivi, akakura echokwadi kune akadhindwa saizi kazhinji mukati me0.8mm.Vanobata geji yavo zvakanaka asi vanowanzo dhiraivha zvishoma kudarika mabhatani mabhatani.Vanosarudzika kumabhatani mabhatani ekumisikidza friction pazvinogoneka.
Mabhoti anofanirwa kuiswa sepadhuze neperpendicular kune dombo pamusoro sezvinobvira.Izvi zvinoita kuti mhete yakasungwa yasangana nendiro kumativi ese.Mabhaudhi asina perpendicular kune ndiro uye dombo pamusoro achaita kuti mhete itakurwe pane imwe nzvimbo inogona kukonzera kutadza kwekutanga.Kusiyana nemamwe mabhoti ematombo, spherical seat washers haawanikwe kugadzirisa angularity ane frictional stabilizers.
Zvishandiso zvemutyairi zvinofanirwa kuendesa simba repercussive kubhaudhi panguva yekuisa, kwete simba rekutenderera.Izvi zvinopesana nemamwe marudzi mazhinji erutsigiro rwepasi.Mugumo weshank yemutyairi unofanirwa kuve wakareba kuti ubate piston yekubooresa mune zvinomisa uye jacklegs (kureva 41/4" kureba 7/8" hex drill simbi).Iyo shank inopera kune vatyairi yakatenderedza kuitira kuti isaite kutenderera kwechibooreso.Zvishandiso zvemutyairi zvinofanirwa kunge zvine chimiro chakakodzera chekupedzisira kuti chikwane mukukwesha pasina kusunga uye kukonzeresa kukuvara kwebhaudhi panguva yekuisa.
Dzidzo yakakodzera yevashandi vemigodhi nevatariri inosungirwa.Sezvo kushanduka kwevashandi kuchiwanzoitika muvashandi vanogadzira mabhaudhi, dzidzo inofanira kuramba ichienderera mberi.Vashandi vane ruzivo vachachengetedza mari munguva refu.
Kuiswa kunofanirwa kutariswa kuti ive nechokwadi chekuti maitiro uye kunaka kwakachengetedzwa.Dhonza-yedzo zviyero zvinofanirwa kuitwa nguva nenguva pane friction stabilizer kutarisa yekutanga anchorage values.
