Abantu boshishino kufuneka bazikhethe njani izixhobo zokomba amatye?
Ngophuhliso olukhawulezayo lolwakhiwo loqoqosho lwehlabathi, imfuno yezixhobo zokomba amatye kwiinkalo zobunjineli ezifana nemigodi, ukwakhiwa kwamandla, ulwakhiwo lweziseko ezingundoqo kunye nophuhliso lwendlela yothutho lubonise indlela enyukayo, kwaye iimfuno eziphezulu ziye zabekwa phambili zomgangatho, ezahlukeneyo. kunye nokusebenza kweemveliso zezixhobo zokubrawuza.
Ngokweentlobo zoomatshini bokwemba amatye abasetyenziswa kwiiprojekthi zokomba ze-geotechnical, iimveliso zezixhobo zokugrumba amatye ezixhasayo zinokwahlulwa ngokweendidi ezintandathu: Izixhobo eziphezulu zokomba ihamile, ezantsi kwe-Hole Hammer Bits, izixhobo zokugrumba i-injini yemigodi, izixhobo zokwemba i-patio kunye izixhobo zokomba zokuphonononga ngokwejoloji.
Izixhobo eziphezulu zokugaya isando
Izixhobo eziphezulu zokwemba ihamile zibekwe phezulu koomatshini bokomba amatye. Ixhomekeke kwipiston ye-rock drill ukuba ichaphazele ngokuthe ngqo umsila wesixhobo sokubrawuza. Amandla empembelelo eveliswayo afikelela kwintloko yokubrawuza ngomzimba ogqabhukileyo ngendlela yamaza oxinzelelo ukugqiba ukuqhekeka kwamatye. Le ndlela yokomba ilitye isebenzisa irhasi ecinezelweyo okanye ioyile yolwelo olumanzi njengomthombo wamandla, kwaye amandla empembelelo anokuyilwa ngokweemfuno zesixhobo, ngoko ke inomgangatho ophezulu.ukugrumba amatyeizinga. Ubunzulu bomngxuma wolu hlobo lwesixhobo sokubhoboza ngokuqhelekileyo aludluli kwi-35M, kwaye ububanzi bokugaya abudluli kwi-152M. Isixhobo sokugrumba ilitye sinokohlulwa ngokubanzi ngokwezi ndidi zilandelayo:
(1) Izixhobo zebrazing koomatshini abalula bokutshiza amatye. Ubunzima bolu hlobo lomatshini wokugrumba ilitye lungaphantsi kwe-35KG. Isebenzisa ukubamba ngesandla ngesandla okanye inkxaso yomlenze womoya njengeqonga elisebenzayo. Impembelelo kunye nokuqhutywa kokwembiwa kwamatye kuncinci. Ngokuqhelekileyo, iimveliso zezixhobo zokuqhafaza ziyi-H19mm kunye ne-H22mm i-hexagonal edibeneyo yokuqhafaza i-brazing rods, kunye ne-38-42mm iintloko zokubethelwa kwe-flat-shaped, iintloko ezinqamlekileyo kunye namazinyo amane kunye namazinyo amahlanu e-Tapered button bit Rock Drill.
Ezona mveliso zinkulu zokomba ilitye elikhanyayo ezisetyenziswa kwimarike yobunjineli bokwemba amatye yasekhaya ziintonga eziqhagamshelwe kwikhowuni eziyi-H22mm kunye neentloko zesolder ezimile njengeflake. Phakathi kwazo, i-Φ38-Φ43mm i-spherical enamazinyo amane kunye ne-five-tooth-tooth-tooth connection brazing head sisixhobo sokwemba ilitye elikhanyayo eliphuhliswe kwiminyaka yakutshanje kunye nombhobho wokubhola we-H22mm. Ngenxa yobomi bayo obuzinzile benkonzo kunye nesantya sokugrumba ngokukhawuleza kwiintlobo zamatye aqinileyo, iye yaqatshelwa yiyunithi yokwakha.
(2) Izixhobo zokwembiwa kwemigodi kwimigodi ephantsi komhlaba. Imithombo yemigodi engaphantsi komhlaba inika umlinganiselo omkhulu wemithombo yemigodi. Ngokwesiqhelo, ukomba oluphantsi komhlaba lungohlulwa lube ziindlela ezintathu: ukugrumba amatye angekho nzulu (6m), ukugrumba amatye kumngxuma ophakathi (ubunzulu bepore 10-30m) kunye nokugrumba amatye okunzulu (ubunzulu bomngxuma 50-60m). Kwimingxuma ene-aperture engaphantsi kwe-43mm, i-H22mm i-cone-connected brazing rods kunye ne-flat-blade, i-cross-shaped, okanye i-spherical-tooth rod brazing idla ngokusetyenziswa. Kwimingxuma enemingxuma engaphezulu kwe-43mm, i-R32-H25-R32*1000m yombhobho we-dirll isetyenziswa, ikhatshwa ziintloko ezingqukuvayo okanye ezingqukuva zamatye okubhola.
