Mubasa rekugadzira michina yemagetsi, kunyatsoboorwa kwemabhodhi emagetsi akadhindwa (PCBS) kwakakosha zvikuru, sezvo kuchikanganisa zvakananga kuiswa kwezvikamu zvemagetsi zvinotevera uye mashandiro emasekete. Munguva yekushandiswa kwezvigadziko zvesimbi zvechinyakare, dambudziko rekuzununguka rinowanzoita kuti maburi ePCB ashanduke, izvo zvave dambudziko guru rinodzivisa kuvandudzwa kwekunyatsoboorwa. Hwaro hwegranite, hune hunhu hwahwo hwakasiyana uye zvakanakira chivakwa, hunopa mhinduro inoshanda kudambudziko iri.
Chikonzero chikuru chekutsauka kweborehole kunokonzerwa nekudengenyeka kwesimbi yakakandwa
Kuwanda kwechisikigo kwezvinhu zvakagadzirwa nesimbi yakakandwa kwakaderera. Munguva yekushanda kwemidziyo yekuboora, kunyanya kana chidimbu chekuboora chinotenderera nekukurumidza chikasangana nesimbi yakachekwa, kurira kunowanzoitika. Kurira uku kuchaita kuti chigadziko chesimbi yakakandwa chigadzire kurira kusingafaniri kuregeredzwa. Kunyangwe hupamhi hudiki hwe vibration hucharamba huchiunganidzwa uye huchiwedzera panguva yekuboora kwakanyatsojeka, zvichizopedzisira zvaita kuti chidimbu chekuboora chibve panzvimbo yachakaiswa pakutanga. Uyezve, kushanda kwesimbi yakakandwa kwakaderera, zvichiita kuti zviome kukurumidza kuderedza simba re vibration, zvichikonzera nguva yakareba yekubvunda uye kuwedzera mwero we borehole offset.
Hunhu hwakanaka hwepasi pegranite hunodzivirira kudedera
Granite ine hunhu hwakanaka hwekunyorovesa. Chimiro chayo chemukati chekristaro chakamanikana uye chinogona kunyudza uye kushandisa simba rekunyorovesa zvinobudirira. Kana michina yekudhonza ichishanda uye ichiburitsa kudedera, hwaro hwegranite hunogona kuderedza zvakanyanya amplitude yekunyorovesa munguva pfupi zvikuru. Tsvagiridzo inoratidza kuti chiyero chekunyorovesa chegranite chakapetwa kakawanda kupfuura chesimbi yakakandwa. Izvi zvinoreva kuti inogona kushandura simba guru rekunyorovesa kuita simba rekupisa nedzimwe mhando dzesimba munguva pfupi uye kuabvisa, nokudaro ichideredza zvakanyanya kukanganiswa kwekunyorovesa pamabasa ekudhonza, ichiva nechokwadi chekuti drill bit inogona kurovera zvakadzikama munzira yakatarwa, uye ichideredza zvinobudirira kuitika kwezviitiko zve offset.
Chivimbiso chekuomarara kwakanyanya uye kugadzikana
Hwaro hwegranite hunewo kusimba kwakanyanya uye kugadzikana. Kuwanda kwahwo kwakanyanya uye simba rahwo rekudzvanya rakakwira kupfuura resimbi yakakandwa. Munguva yekuboorwa, hunogona kutsungirira kumanikidzwa kukuru kunoshandiswa ne drill bit uye kumanikidzwa kwakasiyana-siyana kwemuchina kunokonzerwa nekushanda kwemuchina, uye hahuna kuchinja. Kunyangwe kana huchishanda kwenguva refu kana kukanganiswa kudiki kwekunze, hugaro hwegranite hunogona kuchengetedza kugadzikana kwechimiro chahwo uye kupa rutsigiro rwakasimba uye rwakavimbika rwemuchina wekuboorwa. Rutsigiro urwu rwakagadzikana runovimbisa kuti nzvimbo dzechikamu chimwe nechimwe chemuchina wekuboorwa dzinoramba dzakanyatsojeka nguva dzese, nokudaro zvichivimbisa kunyatsorongeka kwekuboorwa.
Kubatsira kwekugadzikana kwekupisa kunodzivirira kuwedzeredza kuzununguka
Pamusoro pekudzivirira kwayo kudedera, kugadzikana kwekupisa kwegranite kunoshamisawo. Munguva yekuboorera, kukweshana pakati pechiboorera nesimbi yepepa kunounza kupisa, uye mashandiro emidziyo anogonawo kukonzera kuwedzera kwekushisa kwenzvimbo. Hwaro hwesimbi yakakandwa hunokanganiswa zvikuru nekuchinja kwekupisa. Kuwedzera kwekupisa uye kudzikira kwekupisa zvinogona kukonzera nyore nyore kuchinjika uye kudedera, izvo zvinokanganisa kunyatsorongeka kwekuboorera. Kuwanda kwekuwedzera kwekupisa kwegranite kwakaderera zvakanyanya. Kana tembiricha ikachinja-chinja, shanduko dzayo dzehukuru dzinogona kuregeredzwa. Izvi zvinodzivirira kuwedzereka kwekuwedzereka kunokonzerwa nekushanduka kwekupisa, zvinogadzira nzvimbo yekushanda yakagadzikana yekushanda kweboorera, uye zvinoderedza mukana wekuboorera kunze.
Mukutsvaga mabasa ekuchera maPCB akanyatsogadzirwa, granite base, ine simba rayo rekudzivirira kutenderera, kuomarara kwakanyanya, kugadzikana kwakanyanya uye kugadzikana kwakanyanya kwekupisa, inogadzirisa zvinobudirira dambudziko rekuchera rinokonzerwa nekutenderera kwesimbi kubva muzvinhu zvakasiyana-siyana. Inopa rutsigiro rwakavimbika kune michina yekuchera maPCB, inobatsira indasitiri yekugadzira macomputer kugadzira mabhodhi edunhu akadhindwa emhando yepamusoro, uye inosimudzira indasitiri yese kuti ikure nenzira chaiyo uye yepamusoro.
