Ka hana o ka bentonite auwaha
1. Nā lima kiaʻi
ʻO ka lepo i hana ʻia i ka bentonite he viscosity maikaʻi, no laila i ka hana ʻana i ka auwaha, ʻo ka pā ākea i hana ʻia e ka ʻōpala i hana ʻia me ka bentonite e pale i ka paia o ka lua a puni i ka manawa e pale ai i ka wai mai ka hāʻule ʻana o ka pā puka, no laila ʻoi loa ka viscosity o ka bentonite lepo maikaʻi. maikaʻi, maʻalahi ke hoʻopili i ka paia o ka puka a hana wikiwiki i kahi kiʻi pale, pale i ka wai mai ka holoi ʻana i ka paia o ka lua, a pāʻani i kahi kuleana nui i ka pale ʻana i ka hāʻule.
2. me nā ʻōpala
I ke kaʻina hana o ka auwaha ʻole, ma o ka ʻeli ʻana o ka drill bit, e nui ana ka pōhaku i ʻoki ʻia a me ke one maikaʻi, a he mea nui ka hoʻokuʻu ʻana i nā ʻāpana pōhaku i ʻoki ʻia i waho o ka lua hana i ka manawa.ʻO ka lepo i hana ʻia me ka bentonite he hoʻomaha maikaʻi a hiki ke lawe mai i nā ʻōpala i hana ʻia i ka wā o ke kūkulu ʻana i waho o ka lua hana, i hiki ai i ka auwaha ke holo mālie.
3. Lubrication
I ka hana ʻauwaha ʻole, ʻike ʻia ka hana drill bit i nā ʻano geology like ʻole i ka manawa like, ʻano paʻakikī kekahi e like me nā papa pōhaku a me nā ʻiliʻili.Ma kēia hana sublayer, koʻikoʻi loa ka ʻaʻahu ʻana o ka drill bit.I ka manawa like, ʻo ka lepo i hana ʻia i ka bentonite he hopena lubrication maikaʻi, hiki ke lubricate i ka drill bit i ka wā o ke kūkulu ʻana a hoʻopau i ka wela i ka manawa like.Hoʻonui kēia i ke ola lawelawe o ka drill bit a hōʻoia i ka hoʻomohala maʻalahi o ka papahana.
Pehea e koho ai i ka bentonite trenchless
Pono mua ke koho ʻana i ka bentonite trenchless ma ke ʻano o ka papahana, a ʻokoʻa nā koi o nā papahana like ʻole.Hiki ke hoʻokaʻawale ʻia kēia i nā ʻauwaha ʻole a me nā ʻauwaha ʻole.ʻO ka hoʻoheheʻe ʻana a me ke kaha kiʻi paipu, nā mīkini pale a me nā mīkini pale no ke kūkulu ʻana;ʻO ka ʻeli ʻaila a me ka ʻimi ʻāina no ka ʻimi ʻauwaha kūpaʻa.ʻO kēia mau ʻano hana hoʻokele ʻole ʻelua he mau koi ʻokoʻa loa no ka bentonite.
ʻO ke kiʻekiʻe o ka viscosity e koi ʻia e ka hoʻohana ʻole ʻana i ka bentonite, ʻoi aku ka maikaʻi o ka hoʻohana ʻana.ʻO ka mea maʻamau, koho ʻia ka viscosity (600 rpm viscometer heluhelu) ma luna o 40. Inā pili ke kahua kūkulu i kahi one one maʻemaʻe, ʻoi aku ka maikaʻi o ke koho ʻana i kahi viscosity ʻoi aku ma mua o 60, a ʻo ka ratio o ka bentonite a me ka wai ʻaʻole i emi iho ma mua o 5 %.Eia ka ʻōlelo paipai e pili ana i ka lepo lepo i hana ʻia ma Liaoning a me ka lepo lepo i hana ʻia ma Inner Mongolia.ʻO ka viscosity kiʻekiʻe, ka hopena hoʻohana maikaʻi.
Vertical non-driven non-driven bentonite, ka viscosity maʻamau ma kahi o 35. ʻOi aku ka maikaʻi o ka viscosity o ka bentonite ponoʻī, me ka hoʻohui ʻole ʻana i nā tackifiers.Ma muli o ka hoʻonui ʻana o ka tackifier i ka hohonu i ka wā e hoʻoheheʻe ʻia ana, e nalowale ka mahana i kona hopena ma hope o 300 degere Celsius.I ka manawa like, loaʻa iā ia kekahi hopena hoʻopōʻino i ka drill bit.No laila, pono e koho ʻia ka bentonite auwaha i hana ʻia mai ka bentonite kiʻekiʻe.
I ka pōkole, pono e hoʻoholo ʻia ke koho o ka bentonite trenchless e like me ke kūlana maoli o ke kahua kūkulu.E noʻonoʻo pū i ke kumukūʻai o ka hoʻohana.
