Daim Ntawv Thov Ntau
Nws yog tsim rau drilling dej qhov dej, qhov dej kub hauv qhov dej, luv luv mircopiles nruab nrab mini-hom grouting qhov ntawm lub tsev, pas dej ua ke thiab chaw nres nkoj project.
Cov Cai Tsim
Ua kom lub casing ua raws li yooj yim thiab cov khoom siv thiab kev ua haujlwm yooj yim
Qhov zoo tshaj plaws
Cov qauv yooj yim, kev ua haujlwm yooj yim, txhim khu kev qha zoo, cov cuab yeej drilling rov qab, lub neej ua haujlwm ntev.
Cov txheej txheem ua haujlwm:
1. Thaum lub drilling pib, lub reamer qhib thiab nthuav lub qhov kom tsav lub casing khau thiab casing tube down.
2.Thaum drilling nyob rau hauv lub over-burden tsim yog ua tiav, Pib rov qab mus kaw lub reamer, thiab ces rub lub sib dhos los ntawm lub casing raj.
3.Lub casing tube tuaj yeem tso rau hauv lub qhov, lossis tuaj yeem rub tawm los ntawm cov khoom siv grout sealing.
4.Siv cov cuab yeej drilling li qub los laum thiab ua tiav rau qhov xav tau qhov tob.

Kev siv:
1. Nyob rau hauv lub pob zeb tsis ruaj khov, lub casing yuav tsum tau ua raws li.
2. Feem ntau hauv cov dej zoo drilling, rau qhov loj qhov tho txawv.
3. Drilling qhov tob yog zoo dua tsawg dua 40 meters los tswj lub qhov zoo.
4. Sib phim rau 6 "rauj thiab 194mm casing raj.
5. Cua siab yog 20 Bar thiab huab cua ntim yog 500 cfm.
6. Cov cuab yeej raug muab coj los siv rau hauv lub qhov tom ntej.
