Esihlabathini, i-rock pan kanye neminye inhlabathi ene-resistivity enkulu yomhlaba, ukuze kuhlangatshezwane nezidingo eziphansiukubeka phansiukumelana, isisekelo

igridi eyakhiwe ngezindikimba eziningi zaphansi ngokuhambisana ivame ukusetshenziswa.Nokho, ngezinye izikhathi izinto eziningi zensimbi ziyadingeka futhi

indawo yokubeka phansi inkulu kakhulu, ngakho-ke kuvame ukuba nzima ukufeza ukumelana okudingekayo kwesisekelo.Ngalesi sikhathi, singazama ukunciphisa umhlaba

ukumelana nenhlabathi eseduze nomzimba ophansi, futhi futhi ufeze umgomo wokunciphisa ukumelana nesisekelo.

1. Sebenzisa umhlabathi ongazweli kahle (okungukuthi indlela yokushintsha inhlabathi)

Ubumba, i-peat, inhlabathi emnyama kanye nobumba oluyisihlabathi kusetshenziswa esikhundleni senhlabathi yokuqala nge-coefficient yokumelana nogesi ophezulu, kanye ne-coke namalahle.

ingasetshenziswa futhi uma kunesidingo.Uhla lokushintshwa luyi-1~2m ukuzungeza i-electrode ephansi kanye ne-1/3 ye-electrode ephansi endaweni

eduze komhlabathi.Ngemuva kokwelashwa okunjalo, ukumelana nesisekelo kungancishiswa kuze kufike ku-3/5 yenani lokuqala.

2. Ukwelashwa okwenziwayo njengokufaka usawoti

Faka usawoti, i-coal cinder, uthuli lwekhabhoni, umlotha wesithando somlilo, umlotha we-coke, njll. emhlabathini ozungeze umzimba ophansi ukuze uthuthukise ukuhamba kwenhlabathi.

Okuvame ukusetshenziswa kakhulu usawoti.Ngenxa yokuthi usawoti unomthelela omuhle ekuthuthukiseni i-coefficient yokumelana nomhlabathi, awukho ngaphansi kwezinkathi ezithile zonyaka

izinguquko,futhi intengo iphansi.Indlela yokwelapha ukumba umgodi onobubanzi obungaba ngu-0.5 ~ 1.0m ukuzungeza umzimba ngamunye ophansi, bese ugcwalisa

usawoti kanye nomhlabathikungqimba lomgodi ngongqimba.Ngokuvamile, ugqinsi longqimba lukasawoti luba ngu-1cm, kanti ugqinsi lwenhlabathi luba ngu-10cm.Isendlalelo ngasinye

kasawoti kufanele kubeomanziswe ngamanzi.Ukusetshenziswa kukasawoti we-tubular grounding body cishe ku-30-40kg;Le ndlela inganciphisa i-grounding

ukumelana neokwangempela (1/6-1/8) okwenhlabathi enesihlabathi kanye (2/5-1/3) nobumba olunesihlabathi.Uma wengeza mayelana namalahle angu-10kg, umphumela uzoba ngcono.Njengamalahle

iqinileumqhubi, ngeke ahlakazwe, angene futhi agqwale, ngakho-ke isikhathi sawo esisebenzayo side.Ngensimbi eyisicaba, insimbi eyindilinga nokunye okuhambisanayo

ukubeka phansiimizimba, imiphumela engcono ingatholakala ngokusebenzisa izindlela ezingenhla.Kodwa-ke, le ndlela nayo inemibi, njengomphumela omncane

emadwaleni kanyeinhlabathi enamadwala amaningi;Ukuzinza komzimba ophansi kuyancishiswa;Izosheshisa ukugqwala komzimba ophansi;Umhlabathi

ukumelana ngekekancane kancane ukwanda ngenxa yokuncibilika kancane kancane nokulahlekelwa usawoti.Ngakho-ke, idinga ukwelashwa kanye eminyakeni emi-2 ngemuva kokwelashwa okwenziwa ngesandla.

3. Ingaphandleukubeka phansi

Ikakhulukazi ezindaweni ezinamagquma, lapho inani lokumelana nesisekelo lidingeka libe lincane futhi kube nzima ukufinyelela endaweni, uma kunomthombo wamanzi noma

inhlabathi ene-coefficient ephansi yokumelana eduze, indawo ingasetshenziswa ukwenza ama-electrode aphansi noma ukubeka igridi ephansi yamanzi.Bese, sebenzisa

intambo yaphansi (efana nomugqa wensimbi oyisicaba) ukuyixhuma njengendawo yangaphandle.Nokho, kufanele kuqashelwe ukuthi isisekelo sangaphandle

idivayisi kufanele igweme ishaneli yabahamba ngezinyawo ukuvimbela ukushaqeka kukagesi okubangelwa i-voltage yesinyathelo;Lapho uwela umgwaqo omkhulu, ukujula okungcwatshwe kwe

umthofu wangaphandle akufanele ube ngaphansi kuka-0.8m.

4. Ukhonkolo oqhutshwayo

I-carbon fiber ixutshwa kusimende ukuze isetshenziswe njenge-electrode ephansi.Isibonelo, cishe i-100kg ye-carbon fiber yengezwa ku-1m3 kasimende

ukwenza i-hemispherical (1m ububanzi) i-electrode ephansi.Ngokulinganisa, ukumelana nokuqina kwemvamisa yamandla (uma kuqhathaniswa

ngokhonkolo ojwayelekile) ingancishiswa cishe ngama-30%.Le ndlela ivame ukusetshenziselwa ukuvikela umbani kanye nemishini yokubeka phansi.Ku

ukuze kuqhutshekwe kuncishiswe ukumelana nokugxiliswa kwe-impulse, i-electrode eyi-grounding efana nenaliti nayo ingashunyekwa ku-conductive.

ukhonkolo ngasikhathi sinye, ukuze i-corona yokukhipha ikwazi ukuqhubeka igaya igagasi kanye ne-carbon fibre ephuzwini lenaliti, ene-

umphumela osobala ekwehliseni ukumelana nomfutho.

5. Ukwelashwa ngamakhemikhali nge-ejenti yokunciphisa ukudonsa

I-ejenti yokunciphisa ukumelana isebenzisa i-carbon powder kanye ne-quicklime njengezinto zokusetshenziswa eziyinhloko zingasetshenziswa emhlabathini isikhathi eside futhi zizokwenza.

angalahleki ngenxa yamanzi angaphansi komhlaba ngoba awanayo i-dielectric, ngakho-ke angathola indawo ephansi engangcoli futhi ezinzile.

ukumelana (cishe i-1/2 ephansi kunaleyo ngaphambi kokusebenzisa i-ejenti yokunciphisa ukumelana nokwelapha inhlabathi).Ukuze uthole indawo ye-hard rock plate, indlela ye

intambo yokungcwaba kanye ne-ejenti yokunciphisa ukumelana iyasebenza impela, futhi ukumelana kwayo nokuqina kungancishiswa cishe ngo-40% uma kuqhathaniswa.

ngalolo lokungcwaba ucingo oluphansi kuphela.Ngaphezu kwalokho, le ndlela ingafinyelela imiphumela emihle inqobo nje uma i-agent yokunciphisa ukumelana ne-powdery noma

i-ejenti yokunciphisa isikhathi eside ifafazwa emseleni ombiwe wabekwa ngocingo oluphansi, bese inhlabathi endala igcwaliswa ngemuva.

6. Indlela yokungcwaba ejulile yemigodi

Le ndlela ibikwe phesheya isikhathi eside, futhi izuze imiphumela emihle ekusebenziseni okungokoqobo.Eminyakeni yamuva nje, i-China nayo

waqala ukusebenzisa le ndlela entsha yokunciphisa ukumelana.Ubude bomzimba ophansi oqondile osetshenziswe kule ndlela ngokuvamile u-5 ~ 10m

kuye ngezimo zokuma komhlaba.Uma kuyinde, umphumela ngeke ubonakale futhi ukwakhiwa kuzoba nzima.Isisekelo

umzimba ngokuvamile usebenzisa Φ 20~75mm insimbi eyindilinga.Umthelela wensimbi eyindilinga enama-diameter ahlukene ekuphikiseni okuphansi kakhulu

encane.Le ndlela isetshenziswa ezakhiweni eziminyene noma ezindaweni eziwumngcingo lapho kubekwa khona amagridi aphansi.Kulezi zimo, kunzima

thola isikhundla esifanele se-electrode egxiliwe engcwatshwe ngezindlela zendabuko, futhi ibanga eliphephile alikwazi ukuqinisekiswa.Nakuba i-

ukuphepha kungaqinisekiswa ngokumboza umzimba ophansi nge-asphalt insulating layer, umthwalo womsebenzi wokwakha kanye nezindleko zokufaka

anda.Indlela yokungcwaba ejulile iyindlela ephumelela kakhulu yenhlabathi enesihlabathi, ngoba izingqimba zayo eziningi eziyisihlabathi zisendaweni engaphezulu.

ngaphakathi kwe-3m, kuyilapho ukumelana nenhlabathi kungqimba ejulile kuphansi.Ngaphezu kwalokho, le ndlela iyasebenza nasezindaweni zamatshe amatshe.

Ngesikhathi sokwakha Φ Umshini omncane we-auger owenziwe ngesandla noma wokubhola onobubanzi obungu-50mm nangaphezulu.Kugqitshwe embobeni ebhoboziwe Φ 20~75mm

umzimba oyindilinga wensimbi ophansi, bese ugcwaliswa ngodaka lwekhabhoni (ohlanganiswe ne-carbon fiber water slurry) noma udaka.Ekugcineni, izisekelo eziningana

imizimba enempatho efanayo ixhunywe ngokuhambisana ukuze yakhe indikimba eyisisekelo ephelele.Umzimba ophansi owakhiwe ngale ndlela

ayithinteki kangako yizinkathi zonyaka futhi ingathola ukumelana nokuqina okuzinzile.Ngesikhathi esifanayo, ngenxa yokungcwatshwa okujulile, i-voltage yesinyathelo nayo ingaba

kuncishiswe kakhulu, okuzuzisa kakhulu ekuvikelweni kokuphepha komuntu siqu.Le ndlela ilungele ukwakhiwa, izindleko eziphansi futhi

okuphawulekayo ngomphumela, okuzokwenziwa kudume futhi kusetshenziswe.
