The outer diameter of limiting stand collectively forms guide sleeve by both ends limit casing and stage casing casing, the outer diameter of the guide sleeve at
Bore dia matches.
The characteristics of stone matter tunneltron canopy method for controlling planeness of the present invention is to carry out as follows：
Step 1：Aperture guide pipe is made in tunnel portal or section Portal Section；
Step 2：Stone matter tunneltron canopy flatness control device described in claim 1 is made, is behind drill bit
Guide sleeve is set on the first segment drilling rod of impactor；
Step 3：Drilling machine starts to creep into the guide pipe of aperture, obtains initial guiding using aperture guide pipe, passes through spreading
Drilling rod is constantly pushed ahead；
Step 4：With going deep into for drilling machine, front end drill bit is obtained using the guide sleeve being arranged on the first segment drilling rod
Front end is oriented to, and avoids deviation, while coordinating the limit of aperture guide pipe, realizes the flatness control of whole drilling rod.
The characteristics of stone matter tunneltron canopy method for controlling planeness of the present invention, lies also in：
For mountain tunnel hole, concrete of constructing first is oriented to wall, and is oriented to embedded steel tube conduct in wall in concrete
Aperture guide pipe；
For Subway Tunnel, steel pipe is fixed temporarily on the side wall of subway station as aperture guide pipe.
The present invention has the beneficial effect that compared with prior art：
1, the present invention makes drill bit in drilling process obtain good lead using the guide sleeve being arranged on first segment drilling rod
To avoiding its that apparent deviation occurs, also therefore avoid the influence because of steel pipe deviation to tunnel cutting；
2, the straight of pipe canopy pore-forming has been effectively ensured using front end guide sleeve and tie tail aperture guide pipe in the present invention
Degree；The steel pipe after pore-forming is smoothly installed, project progress is greatly improved, ensures pipe canopy quality.
Description of the drawings
Fig. 1 is guide sleeve and first segment drilling rod fit structure schematic diagram in the present invention；
Fig. 2 is drilling machine advanced state schematic diagram in the present invention；
Figure label：11 drill bits, 12 impactors, 13 drilling rods, 13a first segment drilling rods, 13b guide sleeves, 14 apertures are oriented to
Pipe, 102 limiting stands, 103 limit casings, 104 stage casing casings.
Specific implementation mode
The structure type of stone matter tunneltron canopy flatness control device is in the present embodiment：It is arranged in the periphery of drilling rod and is oriented to
Casing, outer diameter and the drilling diameter of guide sleeve match, can be relatively rotated between guide sleeve and drilling rod, and with axial
Limit, enables guide sleeve that drilling rod to be followed to be crept into；In specific implementation, guide sleeve is provided in closest to drill bit
On first segment drilling rod.
Referring to Fig. 1, the setting in the present embodiment for guide sleeve is using the boss at the both ends of drilling rod 13 as limiting stand
102, it is set with limit casing 103 in the both ends of drilling rod 13 and the outside that is in limiting stand 102, the limit casing 103 at both ends
Between connect stage casing casing 104；Wherein, the internal diameter of limit casing 103 is less than the outer diameter of limiting stand 102, and is more than drilling rod outer diameter,
