Description
Technical field
This utility model relates to shield-tunneling construction field, is specially a kind of speciality Shield surface drilling cultellation repetition measurement device.
Background technology
China is in subway construction high-tide period, 90% interval employing shield-tunneling construction, and shield tunnel starts to distance, little curve evolution, but under the influence of the various interference of shield-tunneling construction and environment, the wire length of side is laid according to routine the shortest plus hole inside conductor, measurement error is bigger, use Traditional Man repetition measurement cannot ensure penetrating accuracy more than 1200 meters of shield tunnels, cause tunnel deviation bigger because of shield excavation attitude error both at home and abroad, cause reducing overall trip speed, even cannot receive because piercing error is excessive, whole piece tunnel is caused to change into digging rebuilding, artificial repetition measurement is one of most critical operation in shield driving and shield reception.There is presently no and a kind of guarantee speciality shield tunnel driving and through precision best repetition measurement method and apparatus.
Summary of the invention
This utility model cannot meet more greatly driving attitude to solve repetition measurement error when existing speciality shield tunnel tunnels and receive a difficult problem for attitude, it is provided that a kind of speciality Shield surface drilling cultellation repetition measurement device simple, efficient, accurate.
This utility model adopts the following technical scheme that
A kind of speciality Shield surface drilling cultellation repetition measurement device, including molding tunneling shield section of jurisdiction, surface drilling follow-up steel thimble, plumb bob and the oil drum equipped with oil, the vault of molding tunneling shield section of jurisdiction is provided with boring, surface drilling follow-up steel thimble is connected by boring is vertical with molding tunneling shield section of jurisdiction, plumb bob through surface drilling follow-up steel thimble and is fixed on ground by well cabinet frame, and oil drum is located in molding tunneling shield section of jurisdiction, immediately below plumb bob.
Described surface drilling follow-up steel thimble is provided with plugging device in the joint gap of molding tunneling shield section of jurisdiction.
Described plugging device formula is quick cement.
This utility model is to use sleeve pipe follow-up boring after molded shield tunnel vault corning machine is holed from ground, blocks by quick cement grip pipe and section of jurisdiction boring outer void.Finally it is put in tunnel oil drum from sleeve pipe with plumb bob from ground, from hole, draws a repetition measurement and sleeve pipe cultellation is modified, the control point that revised point is received as shield attitude and shield.
Compared with prior art, this utility model has the advantage that
1) surface drilling technique is simple, and floor cultellation repetition measurement is the highest, it is to avoid shield wire extends opens tired error；
2) shield excavation attitude can be adjusted after cultellation repetition measurement in time, it is ensured that shield tunnel tunnels and normally receives, and stops because attitude error causes tunnel to be scrapped；
In a word, it is the highest, noiseless that this utility model makes full use of ground repetition measurement, and plumb bob is put into fuel tank stop the advantage such as swing of cultellation, improves repetition measurement precision, stops because attitude discards tunnel.Flexible and convenient operation, has that technique is simple, advanced technology, an advantage such as practical.
Use this technology to have successfully completed No. 9 lines 7 of Shenyang Metro to mark left and right, Cao Wang interval line shield and execute, realize shield and receive zero error, fill up the blank of China's super long tunnel surface drilling cultellation repetition measurement technology, achieving good economic benefit and social benefit, this practicality is newly applicable to all shield tunnel constructions.

Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Speciality Shield surface drilling cultellation repetition measurement device as shown in Figure 1, 2, including molding tunneling shield section of jurisdiction 3, surface drilling follow-up steel thimble 5, plumb bob 8 and the oil drum 7 equipped with oil, the vault of molding tunneling shield section of jurisdiction 3 is provided with boring 4, surface drilling follow-up steel thimble 5 is connected by boring 4 is vertical with molding tunneling shield section of jurisdiction 3, plumb bob 8 through surface drilling follow-up steel thimble 5 and is fixed on ground by well cabinet frame 6, and oil drum 7 is located in molding tunneling shield section of jurisdiction 3, immediately below plumb bob 8.
Specific construction step includes:
Step one, boring
A, shield originate driving in the middle of tunnel from originating station；B, use and loose core crown drill hole, airborne section of jurisdiction；C, boring of following up from ground employing geological drilling rig sleeve pipe, with cement gap blocking between sleeve pipe and section of jurisdiction boring.
Step 2, cultellation repetition measurement
A, in tunnel, put into oil drum；B, set up well cabinet frame from ground after, plumb bob is put into oil drum from sleeve pipe；C, utilize instrument measurement conscientious to plumb bob center after guide in tunnel.
It is interval to Cao Zhong station speciality that surface drilling cultellation repetition measurement described in this practicality has been used for No. 9 line 7 Biao Wang river way stations of Shenyang Metro, interval long 2240 meters.After Hun River is passed through in shield driving, after ground uses sleeve pipe follow-up boring, utilize plumb bob that ground repetition measurement central point is thrown in tunnel.Realize left and right line shield zero error to receive, and molding tunnel deviation is in error allowed band.Proving this advanced technology, methodological science is reasonable.
Meanwhile, this utility model has been generalized in other speciality shield tunnels driving, has been greatly improved shield driving attitude repetition measurement precision, guarantee super long tunnel shield driving and reception, achieve good economic benefit and social benefit, in practice it has proved that, this technical scheme is practical, and promotion prospect is good.
