Isishwankathelo seTRD

Intshayelelo ye-TRD •
I-TRD (i-Trench cutting Re-mixing Deep wall method), indlela yokwakhiwa kwendonga eqhubekayo phantsi komhlaba we-samente ubukhulu obulinganayo, eyaphuhliswa yi-Kobe Steel yaseJapan ngo-1993, esebenzisa ibhokisi yokusika i-saw chain ukuze iqhubeke nokwakha iindonga eziqhubekayo phantsi kobunzima obulinganayo bomhlaba we-samente Construction Technology. .
Ubunzulu obuphezulu bokwakha kumaleko omhlaba oyisanti ngokubanzi bufikelele kwi-56.7m, kwaye ubukhulu bodonga yi-550mm ~ 850mm. Ikwafanelekile kwiindidi ezahlukeneyo zesitrato ezifana neengqalutye, amatye kunye namatye.
I-TRD yahlukile kwindlela yangoku yekholamu-uhlobo oluqhubekayo lolwakhiwo lwamadonga phantsi komhlaba we-samente owenziwe ngoomatshini bemveli be-axis okanye i-multi-axis spiral drilling. I-TRD ifaka kuqala isixhobo sokusika i-chainsaw-type kwisiseko, igrumba ubunzulu obuyilwe eludongeni, emva koko ifake i-agent ephilisayo, ixube nomhlaba we-in-situ, kwaye iqhubeke nokugrumba ngokuthe tye kwaye ishukumise, kwaye iqhubela phambili ngokuthe tye ukuya. ukwakha udidi oluphezulu lwesamente eludongeni oluqhubekayo.

Iimpawu zeTRD
(1) Ubunzulu bokwakha bukhulu; ubunzulu obukhulu bungafikelela kwi-60m.
(2) Ilungele uluhlu olubanzi lwezitrato kwaye inokusebenza kakuhle kokomba kwistrata eqinileyo (umhlaba oqinileyo, igrabile esanti, iliwa elithambileyo, njl.njl.)
(3) Udonga olugqityiweyo lunomgangatho olungileyo, kwicala elinzulu eludongeni, linokuqinisekisa umgangatho ofanayo womhlaba wesamente, amandla aphuculweyo, ukucaca okuncinci, kunye nokusebenza kakuhle kokucalula amanzi.
(4) Ukhuseleko oluphezulu, ubude besixhobo yi-10.1m kuphela, iziko eliphantsi lomxhuzulane, uzinzo oluhle, olulungele iindawo ezinezithintelo zokuphakama.
(5) Udonga oluqhubekayo olunamalungu ambalwa kunye nobukhulu obulinganayo bodonga, intsimbi efana ne-H inokusekwa kwindawo efanelekileyo.

Umgaqo weTRD
Ibhokisi yokusika i-chain iqhutywe yi-motor hydraulic yebhokisi lamandla, kwaye amacandelo axhunyiwe kwi-drill ukuya kubunzulu obunqunywe kwangaphambili, kunye nokugrumba okuthe tye kuqhubekele phambili. Kwangaxeshanye, ulwelo oluqinisiweyo lugalelwe emazantsi ebhokisi yokusikwa ukuze luxutywe ngenkani kwaye luvuthulule ngomhlaba okwi-situ, kunye nodonga lokuxuba umhlaba wesamente oluyingqimba olulinganayo lunokufakwa kwiprofayili yentsimbi ukunyusa ukuqina. kunye namandla odonga lokuxuba.
Le ndlela yokwakha itshintsha indlela yokuxuba yodonga lokuxuba lwesamente-yomhlaba ukusuka kumxube wemveli othe tye othe tye we-axis drill intonga ukuya kumxube othe tye othe tye wesarha yesarha ibhokisi yokusika ecaleni kobunzulu bodonga.
