I.Ukuqaliswa kobuchwephesha bokungagrunjwa
Itekhnoloji ye-No-dig luhlobo lweteknoloji yokwakha yokubeka, ukugcinwa, ukutshintshwa okanye ukufumanisa imibhobho engaphantsi komhlaba kunye neentambo ngendlela yokwemba okuncinci okanye ukungagrumbi.Ulwakhiwo lwe-no-dig lusebenzisa umgaqo wobuchwephesha bokwemba i-directional, inciphisa kakhulu uthando lokwakhiwa kwemibhobho engaphantsi komhlaba kwi-traffic, indalo, iziseko zophuhliso kunye nokuhlala kunye nokusebenza kwabahlali, iba yinxalenye ebalulekileyo kwisixeko sangoku sokwakhiwa kobugcisa kunye nolawulo.
Ulwakhiwo olungenamijelo lwaqalwa ngoo-1890 kwaye lwakhula lwaba lishishini ngo-1980 kumazwe aphuhlileyo.Iphuhliswe ngokukhawuleza kakhulu kule minyaka ingama-20 idlulileyo, kwaye ngoku isetyenziswa ngokubanzi kwiiprojekthi ezininzi zokubeka imibhobho kunye nolwakhiwo lolondolozo kumashishini amaninzi afana nepetroli, igesi yendalo, unikezelo lwamanzi, unikezelo lombane, uthungelwano ngocingo kunye nonikezelo lobushushu njl.njl.
II.Umgaqo wokuSebenza kunye namanyathelo oKwakha i-Horizontal Directional Drill
1.Ukutyhalwa kwe-drill bit kunye ne-drill rod
Emva kokulungiswa komatshini, ngokwe-engile emiselweyo, i-drill bit iqhuba intonga ye-drill ijikeleza kwaye iqhube phambili ngamandla entloko yamandla, kwaye iqhube ngokobunzulu obufunekayo kunye nobude beprojekthi, ukuwela imiqobo emva koko kuza emhlabeni. umphezulu, phantsi kolawulo lwelocator.Ngexesha lokutyhala, ukuze kuthintelwe intonga ye-drill ekubambeni kunye nokutshixa ngomaleko womhlaba, kufuneka kwenziwe isamente yokudumba okanye i-bentonite ngempompo yodaka ngokusebenzisa intonga ye-drill kunye ne-drill bit, kwaye ngeli xesha ukuqinisa indlela yokuhamba kunye nokuthintela umngxuma ukusuka. ukungena ngaphakathi.
2.Ukuhlaziya kwakhona kunye ne-reamer
Emva kokuba i-drill bit ikhokelela intonga yokubhola ngaphandle komhlaba, susa i-drill bit kwaye udibanise i-reamer kwi-drill intonga kwaye uyilungise, ukubuyisela intloko yamandla, intonga yokubhola ikhokelela i-reamer ibuyele ngasemva, kwaye yandise ubukhulu be-drill. umngxuma.Ngokutsho kwedayamitha yombhobho kunye nokwahluka, ukutshintsha ubungakanani obuhlukeneyo be-reamer kunye ne-ream kanye okanye amaxesha amaninzi de ufikelele kwi-diameter efunekayo yomngxuma.
3.Thatha umva umbhobho
Xa ufikelela kwidayamitha yomngxuma efunekayo kwaye i-reamer iza kutsalwa umva ngexesha lokugqibela, lungisa umbhobho kwi-reamer, intloko yamandla iya kutsala intonga yokubhola kwaye izise i-reamer kunye nombhobho ukuba ubuyele ngasemva, de umbhobho utsalwe. ngaphandle emhlabeni, imisebenzi yokubeka umbhobho igqityiwe.
