I-Horizontal Directional Drilling Rig: I-Revolutionizing Underground Construction

I-Horizontal directional drilling (i-HDD) ivele njengobuchwepheshe obushintsha umdlalo emkhakheni wokwakha ngaphansi komhlaba, futhi isihluthulelo sempumelelo yakho sisesigabeni sokubhola esiqondile. Le mishini emisha isiguqule indlela efakwa ngayo ingqalasizinda engaphansi komhlaba, ivumela ukufakwa kwezinsiza ezifana namanzi, igesi, nezintambo zokuxhumana ngokuphazamiseka okuncane endaweni engaphezulu. Kulesi sihloko, sizohlola ukubaluleka kwe-drilling rig eqondile kanye nomthelela wayo embonini yezokwakha.

Umshini wokumba oqondile uwucezu olukhethekile lomshini oklanyelwe ukwakha i-borehole evundlile ngaphansi komhlaba. Le nqubo ihlanganisa ukusetshenziswa koketshezi lokumba, ngokuvamile okuyingxube yamanzi nezithasiselo, ukuze kube lula umsebenzi wokumba. I-rig ifakwe umshini onamandla wokumba ongangena ezinhlotsheni ezihlukahlukene zenhlabathi namadwala, okuvumela ukufakwa kwengqalasizinda engaphansi komhlaba ezinhlobonhlobo zezimo ze-geological.

Enye yezinzuzo eziyinhloko zokusebenzisa i-rig yokumba eqondile ikhono layo lokunciphisa ukuphazamiseka kwendawo ngesikhathi sokufakwa kwezinto ezisetshenziswa ngaphansi komhlaba. Ngokungafani nezindlela zokusika ezivulekile zendabuko, i-HDD ivumela ukufakwa kwamapayipi nezintambo ngaphandle kwesidingo sokumbiwa okubanzi, kunciphisa umthelela endaweni ezungezile nengqalasizinda ekhona. Lokhu kwenza i-HDD ibe yisixazululo esifanelekile sezindawo zasemadolobheni, izindawo ezizwela imvelo, nezindawo ezinomkhawulo wokufinyelela.

Ngaphezu kwalokho, i-horizontal directional rig yokumba yenza kufakwe ingqalasizinda kuzo zonke izithiyo ezifana nemifula, imigwaqo emikhulu kanye nezindawo ezinabantu abaningi. Ngokusebenzisa amasu okumba athuthukile namathuluzi akhethekile, izinsimbi ze-HDD zingakwazi ukuhamba ngaphansi kwalezi zithiyo, ziqede isidingo sokuwela indawo ebizayo nephazamisayo. Leli khono likhulise ngokuphawulekayo amathuba okufaka izinsiza ezingaphansi komhlaba ezindaweni eziyinselele nezinezimoto eziningi.

Ngaphezu kwezinzuzo zayo zezemvelo nezokusebenza, umshini wokumba ovundlile unikeza ukusebenza kahle okwandisiwe kanye nokuphumelela kwezindleko ezinhlelweni zokwakha ezingaphansi komhlaba. Ikhono lokufaka imigqa yezinsiza eziningi ngaphakathi kwe-borehole eyodwa kunciphisa isidingo sezindawo zokumba eziningi, ukonga isikhathi nezinsiza. Ngaphezu kwalokho, ukunemba nokunemba kobuchwepheshe be-HDD kunciphisa ubungozi bokubambezeleka kokwakha nokusebenza kabusha okubizayo, okuholela ekongeni ngokuphelele kwephrojekthi.

Ukuguquguquka kwendlela yokumba eqondile eqonde ngqo kunwebeka ekuvumelaneni kwayo nezimo ezihlukahlukene zenhlabathi kanye ne-geological. Noma ngabe ukubhoboza enhlabathini ethambile, idwala eliqinile, noma ukwakheka okuxubile, amarigi e-HDD angahlonyiswa ngamathuluzi okumba akhethekile namasu okuzulazula ngempumelelo ezimweni ezingaphansi komhlaba. Lokhu kuvumelana nezimo kwenza i-HDD ibe inketho ekhangayo kumaphrojekthi amaningi okwakha angaphansi komhlaba, kusukela ekuthuthukisweni kwengqalasizinda yasemadolobheni kuya ekufakweni kwezinsiza zasemakhaya.

Njengoba isidingo sengqalasizinda engaphansi siqhubeka sikhula, umshini wokumba oqondile usuyithuluzi elibalulekile embonini yezokwakha. Amandla ayo okunciphisa ukuphazamiseka kwendawo, ukuhambisa izithiyo eziyinselele, kanye nokuthuthukisa ukusebenza kahle kwephrojekthi kubeke i-HDD njengendlela ekhethwayo yokufaka izinto ezisetshenziswa ngaphansi komhlaba. Ngokuthuthuka okuqhubekayo kubuchwepheshe bokubhola kanye nemishini, umshini wokumba oqondile oqondile ulungele ukudlala indima ebalulekile ekulolongeni ikusasa lokwakhiwa ngaphansi komhlaba.

Sengiphetha, i-horizontal directional rig yokumba isiguqule indlela ingqalasizinda engaphansi komhlaba efakwa ngayo, inikeze isisombululo esimeme, esisebenza kahle, nesingabizi kakhulu semisebenzi eminingi yokwakha. Ikhono layo lokunciphisa ukuphazamiseka kwendawo, ukuzulazula kwezithiyo, kanye nokujwayela izimo ezihlukahlukene zejiyoloji liqinise isikhundla salo njengobuchwepheshe obushintshashintshayo embonini yezokwakha. Njengoba isidingo sezinsiza ezingaphansi komhlaba siqhubeka nokwenyuka, umshini wokumba oqondile uzoqhubeka nokugqugquzela ukusungulwa kanye nenqubekela phambili emisebenzini yokwakha ngaphansi komhlaba.
