I.Ukwethulwa kobuchwepheshe be-no-dig
Ubuchwepheshe be-No-dig luhlobo lobuchwepheshe bokwakha bokubeka, ukunakekela, ukufaka esikhundleni noma ukuthola amapayipi angaphansi komhlaba kanye nezintambo ngendlela yokumba kancane noma ukungamba.Ukwakhiwa kwe-no-dig isebenzisa isimiso sobuchwepheshe bokubhola okuqondisayo, kunciphisa kakhulu uthando lokwakhiwa kwamapayipi angaphansi komhlaba kuthrafikhi, imvelo, ingqalasizinda kanye nokuhlala nokusebenza kwabahlali, kuba yingxenye ebalulekile edolobheni lamanje lokwakhiwa nokuphathwa kwezobuchwepheshe.
Ukwakhiwa kwe-trenchless kwaqalwa kusukela ngo-1890 futhi kwakhula futhi kwaba imboni ngeminyaka yawo-1980 emazweni athuthukile.Ikhula ngokushesha kakhulu kule minyaka engama-20 edlule, futhi njengamanje isetshenziswa kabanzi kumaphrojekthi wokwakha amapayipi amaningi okufakwa nokulungiswa kwezimboni eziningi ezifana nophethiloli, igesi yemvelo, ukuphakelwa kwamanzi, ukuphakelwa kukagesi, ezokuxhumana kanye nokuhlinzeka ngokushisa njll.
II.Isimiso Sokusebenza kanye Nezinyathelo Zokwakhiwa Kwe-Horizontal Directional Drill
1.Ukugxilwa kwe-drill bit kanye nenduku yokubhoboza
Ngemuva kokulungiswa komshini, ngokwe-engeli ebekiwe, i-drill bit ishayela induku yokubhoboza izungeza futhi iye phambili ngamandla ekhanda lamandla, bese iphonseka ngokuya ngokujula nobude obudingekayo bephrojekthi, yeqa izithiyo bese iza phansi. ngaphezulu, ngaphansi kokulawulwa kwendawo.Ngesikhathi sokubhoboza, ukuze kuvinjwe induku yokubhoboza ukuthi ingabambeki futhi ivalwe ngongqimba lomhlabathi, kufanele yenze usimende ovuvukalayo noma i-bentonite ngepompo yodaka ngokusebenzisa induku yokubhoboza kanye ne-drill bit, futhi ngesikhathi sokuqinisa indlela yokuhamba futhi ivimbele umgodi ukuthi ungangeni. ukungena.
2.Ukuphinda usebenzise i-reamer
Ngemuva kokuthi i-drill bit iholele induku yokubhoboza iphume endaweni engaphansi, susa i-drill bit bese uxhuma i-reamer ku-drill rod futhi uyilungise, ubuyisele emuva ikhanda lamandla, induku yokubhoboza iholela i-reamer emuva, futhi andise usayizi we-drill rod. umgodi.Ngokuvumelana nobubanzi bepayipi nokuhlukahluka, ukushintsha usayizi ohlukile we-reamer kanye ne-ream kanye noma ngaphezulu kuze kufinyelele ububanzi bembobo obudingekayo.
3.Hlehlisa ipayipi
Uma ufinyelela kububanzi bembobo obudingekayo futhi i-reamer izodonselwa emuva okokugcina, lungisa ipayipi ku-reamer, ikhanda lamandla lizodonsa induku yokubhoboza bese iletha i-reamer nepayipi ukuthi ihlehle emuva, kuze kube yilapho ipayipi lidonswa. ngaphandle komhlaba, imisebenzi yokubeka ipayipi iyaqedwa.
