Abavelisi kwihoseyile ityuwa ukumelana nombhobho trenchless sokomba bentonite
Indima ye-trenchless bentonite
1. Oonogada bezixhobo
Udaka olwenziwa nge-bentonite lune-viscosity enhle, ngoko ke kwi-trenchless ukwakhiwa, udonga olungenanto olwenziwe ngodaka olwenziwe nge-bentonite lukhusela udonga lomngxuma olujikelezileyo ngexesha lokukhusela ukufuma ekuweni kodonga lomngxuma, ngoko i-viscosity ye-bentonite yodaka oluhle kakhulu. kuhle, kulula ukunamathela eludongeni lomngxuma kwaye ngokukhawuleza wenze ifilimu ekhuselayo, ukuthintela amanzi ekuhlambeni udonga lomngxuma, kwaye udlale indima ebaluleke kakhulu ekuthinteleni ukuwa.
2. ngeetshiphusi
Kwinkqubo yokwakhiwa kwe-trenchless, ngokugrumba i-drill bit, kuya kubakho amatye amaninzi atyunyuziweyo kunye nesihlabathi esihle, kwaye kubaluleke kakhulu ukukhupha iitshiphu zamatye ezichotshoziweyo ngaphandle komngxuma wokwakha ngexesha.Udaka olwenziwa nge-bentonite lunokumiswa kakuhle kwaye luyakwazi ukuzisa i-debris eyenziwa ngexesha lokwakhiwa kwenkqubo yokwakhiwa ngaphandle komngxuma wokwakha, ukwenzela ukuba i-trenchless iqhube kakuhle.
3. Ukuthambisa
Kulwakhiwo olungenamijelo, ulwakhiwo lwentwana ye-drill luya kudibana nejoloji eyahlukileyo ngaxeshanye, ezinye zazo zinobunzima obufana neeleya zamatye kunye negrabile.Kolu lwakhiwo lwangaphantsi, ukunxiba kwi-drill bit kubi kakhulu.Ngelo xesha, udaka olwenziwe nge-bentonite lunomphumo omhle wokuthambisa, onokuthambisa i-drill bit ngexesha lokwakha kwaye uchithe ukushisa ngexesha elifanayo.Oku kwandisa ubomi benkonzo ye-drill bit kwaye iqinisekisa ukuphuhliswa kakuhle kweprojekthi.
Indlela yokukhetha i-bentonite engenazintambo
Ukukhethwa kwe-bentonite engenazintambo kufuneka kuqala kusekelwe kubume beprojekthi, kwaye iimfuno zeeprojekthi ezahlukeneyo ziyahluka.Oku kunokohlulwa ngokulula kwi-horizontal trenchless kwaye nkqo i-trenchless.Imibhobho yokomba ethe tyaba kunye nokuzoba, ukugqobhoza kwemibhobho kunye noomatshini bekhaka bolwakhiwo oluthe tye;Ukwembiwa kwe-oyile kunye nophononongo lwejoloji yeyokuhlola okuthe nkqo kwe-trenchless.Ezi ndlela zimbini zokungaqhubi zineemfuno ezahlukeneyo kakhulu ze-bentonite.
Ukuphakama kwe-viscosity efunekayo ngokusetyenziswa okuthe tye okungavulekiyo kwe-bentonite, kungcono ukuyisebenzisa.Ngokuqhelekileyo, i-viscosity (ukufundwa kwe-viscometer ye-600 rpm) ikhethwe ngaphezu kwe-40. Ukuba indawo yokwakha iyindawo yesanti ecocekileyo, kungcono ukhethe i-viscosity engaphezu kwama-60, kwaye umlinganiselo we-bentonite kunye namanzi awukho ngaphantsi kwe-5. %.Nantsi ingcebiso malunga nomhlaba wodaka oveliswe eLiaoning kunye nomhlaba wodaka oveliswe kwi-Inner Mongolia.I-viscosity ephezulu, umphumo wokusetyenziswa kakuhle.
I-bentonite engaqhubekiyo engaqhubekiyo, i-viscosity ngokuqhelekileyo malunga ne-35. Kungcono ukuba yi-viscosity ye-bentonite ngokwayo, ngaphandle kokongeza i-tackifiers.Ngenxa yokuba i-tackifier inyuka ngobunzulu ngexesha lokomba oluthe nkqo, ubushushu buya kulahlekelwa sisiphumo sako emva kokudlula i-300 degrees Celsius.Ngexesha elifanayo, kunempembelelo ethile eyonakalisayo kwi-drill bit.Ngoko ke, i-bentonite engenamanzi eyenziwe kwi-bentonite ephezulu ye-ore eluhlaza kufuneka ikhethwe.
Ngamafutshane, ukhetho lwe-trenchless bentonite kufuneka lunqunywe ngokwemeko yangempela yendawo yokwakha.Kwakhona qwalasela iindleko zokusetyenziswa.
