Ihamile ePhantsi komngxuma kunye neTekhnoloji yoKwemba umbhobho

Umgaqo wobugcisa

I-DTH isando kunye ne-tube drilling iteknoloji yindlela yokugaya edibanisa i-advantage yesantya somoya we-DTH i-hammer drilling kunye nenzuzo yokukhuselwa kwe-casing eludongeni ehambelana nokuzinza kodonga lwe-borehole.Xa ukomba, i-eccentric drill iphoswa ngaphandle xa ibhloko ye-eccentric ijikeleziswa phambili.Idayamitha ye-eccentric drill ephosiweyo inkulu kunobubanzi be-drill ephakathi.Ngethuba lokugaya, i-casing iqhutywe ngesicathulo sombhobho ukuze ilandele i-synchronously, kwaye ipayipi yensimbi engenamthungo ikhusela Kubaluleke kakhulu ukuzinzisa udonga lomngxuma wokuhlola okudibeneyo kunye nokuvelisa kakuhle ukukhusela udonga lomngxuma ekuweni kunye nokuwa.Xa i-eccentric drill bit drill drill for the forming epheleleyo, emva kokugaya i-0.5 ~ 1 m, ibhloko ye-eccentric ihlehliswa ngokubuyisela umva, kwaye i-eccentric drill ibuyiswa kwi-casing yodonga olukhuselayo, ukwenzela ukuba inkqubo ye-quaternary inokuhamba kakuhle. .Umthwalo ogqithileyo kunye nestratum entsonkothileyo eyaphukileyo.

Iimpawu zobugcisa

1. Isando esisezantsi-umngxuma kunye neteknoloji yokugaya i-tube isebenzisa ngokupheleleyo iingenelo ze-pneumatic down-hole hammer ukuze iphule ngokukhawuleza ilitye, elilungele ukuphuhliswa nokuphunyezwa kokuhlola okudityanisiweyo kunye nokuveliswa kwamaqula kwi-hydrogeological. uphando.

2. Ukulandelela itekhnoloji yokomba inokulandelela i-casing ngelixa ukomba.Ayifuni manzi kunye nodaka lokwembiwa, ngakumbi kwiindawo ezomileyo nezingenamanzi.Inokuphinda kabini umgudu kunye nesiqingatha somzamo, ugweme ubunzima bokuthenga amanzi okugaya, kunye nokuphucula ukusebenza kakuhle.Uphuculo luluncedo kakhulu.

3. Olu hlobo lobuchwephesha bokugaya lusebenzisa i-synchronous casing-up casing ukukhusela udonga xa ubhobhoza, ukusetyenziswa ngokupheleleyo kweenzuzo zomoya we-DTH isando ngokukhawuleza ukuphula ilitye, ngelixa ugcina udonga lomngxuma wechungechunge lwesine lomthwalo obuthathaka obuthathaka. indawo engaphezulu yesitali sokutsala amanzi.I-cuttings ephukileyo iqhutyelwa emngxunyeni ngokuhamba komoya ophezulu, kwaye umphumo wokufunxa unenzuzo ekuvuleni umjelo wokuphuma kwamanzi.Ukuhlanjwa okuqhubekayo kodonga lomngxuma ngomoya ohamba ngesantya esiphezulu kuya kunciphisa ixesha lokuvasa kakuhle, okuluncedo ekuphuculeni ukugrumba kwe-hydrogeological kunye nokusebenza kakuhle kokugqitywa komthombo.

4. Isando esisezantsi-umngxuma kunye neteknoloji yokugaya umbhobho ifanelekile ukugaya ilitye elinzima.Ukubunjwa kodongwe okanye ukubunjwa okuthambileyo okufanayo, kulula ukuvala indawo yomoya kunye nokuchithwa kwe-drill cuttings kulula ukuxhoma eludongeni lomngxuma ukwenza iplagi yodaka, okunzima ukufezekisa ukusebenza kakuhle kwe-drilling .

5. I-casing eqhutywe nge-hammer-hole-hole kunye nombhobho ikhutshwe ngezixhobo ezikhethekileyo emva kokugqiba umsebenzi wokukhusela eludongeni, onokuthi uhlaziywe kwakhona ngexesha elithile, ukunciphisa iindleko zokwakha.
