⑶钻机就位：
钻机下铺钢板，以保证在施工过程中钻机稳定性，靠近钻孔位并将钻头中心直接对准钻位中心，再精确调整机架的垂直度后，将钻头精确定位。
⑷压入钢护筒：
利用钻机专用卡具将底节钢护筒卡放在已钻2～3m的成孔中，利用挖机压入钢护筒。护筒采用约20mm厚的钢板制作，内径约1010mm左右。护筒每节长2.0～3.0m。另外，为了便于灌注砼时泥浆外排，在护筒顶端预留2个开口为40×20cm的出浆口。

⑶ rigs in place:Drilling machine lower plate, in order to ensure stability of the rig during construction near the drill bit drill bit and drill Center directly at Center, after more accurately adjust the squareness of the frame, pull the bit accurately.D onto the steel casing:Rig special clamps to the end of section steel casings in drill 2~3M hole, using digging machines into the steel casing. About 20mm thick steel plate casing, diameter of about 1010mm. Each section longer 2.0~3.0M the casing. In addition, in order to facilitate pouring concrete slurry discharged when, in the top of the casing set aside 2 openings for stock outlet 40x20cm.

⑶ rig in place:
rig steel bunk beds, in order to ensure the stability of the rig in the construction process, drill bit and drill close to the center directly at the center of the drill bit, and then fine-tune the verticality of the rack, the precise positioning of the drill.
⑷ pressed into the steel casing:
the use of special fixtures will rig the bottom section of the steel casing have been drilled into the hole on the card 2 ~ 3m, the use of digging machine pressed into the steel casing. Casings using about 20mm thick steel plate, diameter of about 1010mm or so. Casings for each section length 2.0 ~ 3.0m. Further, in order to facilitate concrete perfusion mud efflux in the casing top reserve two openings 40 × 20cm of the stock inlet.

The driller:The verticality of the rig lower plate to ensure in the construction process of drilling rig stability, near the drill bit and drill center aimed directly at the center position of the drill, and precise adjusting frame, the accurate positioning of the drill bit.The pressure into the steel tube:The use of drilling special fixture will bottom section steel tube card in 2 ~ 3M have been drilled into the hole, pressed into the steel tube by digging machine. The tube is made of steel plate with about 20mm thick, and the inner diameter is about 1010mm. 2 ~ 3.0m of each segment length of the protecting tube. In addition, in order to facilitate the discharge of mud outside the mud, in the top of the retaining tube set aside 2 openings for the 40 x 20cm of the pulp outlet.
