Description
Technical field
The present invention relates to a kind of steel column location straightening method of stand column pile.
Background technology
Constantly expansion, the continuous atrophy of land used along with city size so that construction site is narrow and cutting depth
The situations such as increase occur, conventional suitable way substantially embodies deficiency and problem.In order to solve such problem, China is with reference to external
Advanced construction experience, use Top-down Construction Technique, it is achieved that on the ground and underground structure synchronous construction, shorten the duration, fall
Low construction costs.Interim vertical supporting system during reverse construction typically uses steel column to insert the following stand column pile of base plate
Form, steel column is usually the column of angles, steel core concrete column etc., stand column pile can to use the form such as bored concrete pile or steel-pipe pile,
Reverse construction bears the vertical load such as superstructure and construction loads, and after construction terminates, as middle support column is another
As a part for underground structure post after external wrapping concrete, bear superstructure load, thus the location of middle support column and hang down
Straight degree must strictly meet requirement.General provision middle support column misalignment of axe controls in ± 10mm, absolute altitude control ±
In 10mm, degree control is within 1/300 ~ 1/600.Therefore, the construction of steel column must take special location and straightening,
At present, the vertical adjustment method of steel column mainly has air-bag method, machinery vertical adjustment method and fairlead tube method, achieves certain effect.On
Stating three kinds of methods and have certain practicality and limitation, the perpendicularity of support column is carried out by air-bag method by putting into the air bag in hole
Correcting and location, vertical adjustment is effective, but is restricted by stroke is big, it is impossible to vertical adjustment reaches apart from big steel column perpendicularity with hole wall
Design requirement, further, since air bag is filled with the annular space between conduit and stake holes, therefore, in follow-up concreting
Mud returns out in hole and causes certain obstruction to affect construction quality.Machinery vertical adjustment method is economical and practical, but is only used for rigidity relatively
The tone pitch of big steel column.Fairlead tube method tone pitch is easier to, and effect is also preferable, but owing to guide thimble is outside steel column, makes
Become aperture to become the problem such as big, rear two methods be all fixing steel pipe post top be not fine from stressing conditions.Accordingly, it would be desirable to send out
Bright a kind of tone pitch that can meet steel column and fixing, meanwhile, again can easy to operation, method that operating expenses is low.
Chinese Patent Application No. 201410222301.9, title: a kind of high accuracy vertical pillars stake method of construction, this is special
Profit is the perpendicularity regulating steel pipe post with the bottom of steel wire rope tractive steel pipe post, but due to steel wire rope only at the bottom of steel column
End is connected, not at the bottom of hole, other are fixed, therefore, although after steel pipe post has adjusted, still easily being sent out by other external influences
Raw mobile.
Chinese Patent Application No. 201320057678.4, title: a kind of rotation is dug a steel core concrete column contrary sequence method location and adjusted
Hang down device.The determination of this patent is only in ground secured adjusted, from the point of view of the steel pipe post of overlength, because bottom is not fixed, its
Overall stationary state is not fine, and therefore the scope of application is wide, is only used for steel pipe less, and it is vertical that length is shorter, rigidity is bigger
Stanchion.
Summary of the invention
It is an object of the invention to provide a kind of steel column location straightening method of stand column pile, solve in existing method hole
Deep steel pipe post does not has good control method to constrain the perpendicularity problem of more effectively regulation steel pipe post, and the method is grasped
Make convenient, location is reliable, the simple in construction of the device used, easily manufacture, reusable.
For achieving the above object, the technical solution used in the present invention is: the steel column location straightening side of a kind of stand column pile
Method, it is characterised in that it comprises the steps:
1) the steel column location machine straightening device of stand column pile is prepared: the steel column location machine straightening device of stand column pile includes that 2 groups are determined

2) after column stake holes 21 completes, positioning action platform 22 is installed in aperture, will after positioning with transit survey
The reinforcing in place of positioning action platform；
3) steel reinforcement cage made, steel column are hung in column stake holes 21 from operating platform respectively；
In steel column 1 decentralization process, annular air-pocket 3, ring-shaped clip 5, steel pipe clip 4 are installed in the outside of steel column, Gu
The steel wire reserved, transfers with steel column, and the positioning action platform that steel column 1 is transferred to after design attitude on the ground is first solid
Determine the top of steel column 1, then to be allowed to be fully contacted with hole wall, by the bottom of steel column 1 to annular air-pocket 3 inflation by trachea
It is fixed on the preferable soil layer of stress；
4) terminal laying inclinometer or vertical reference, inclinometer or vertical reference on steel column 1 can be with computer
It is connected, by deviational survey data, artificial or computer controls top and the bottom of steel column 1 are adjusted, steel column 1 time
Portion is by the shifting about the steel wire of tensioning of four direction, front and back respectively of the pawl wheel of two groups of location bar straightening mechanisms on ground
Dynamic, thus the perpendicularity of adjusting post finally ensures the perpendicularity of column；
5) watering and smash concrete Lumen catheter, concrete has some strength (intensity of dismountable annular air-pocket) to remove gas afterwards
Pipe and annular air-pocket, backfill element soil or sandstone, remove positioning action platform.
Innovative point: use the air bag (annular air-pocket) of band annular, ring-shaped clip to be fixed on the hole wall in certain depth, use
Steel wire is connected and by buckling the assembly such as the steel pipe clip of steel pipe, ratchet, directive wheel (pulley) at steel column four direction
Carry out straightening and location.Meanwhile, positioning action platform on ground uses general measure to position and fix steel column (or to claim steel pipe
Column) top, have the requirement reaching to meet design accuracy that the steel column of upper and lower two fixing points is more reliable.
The invention has the beneficial effects as follows: solve deep steel pipe post in existing method hole there is no good control method and
Constraining the perpendicularity problem more effectively regulating steel pipe post, the method is easy to operate, location is reliable, the knot of the device used
Structure is simple, easily manufacture, reusable, low cost, effect is notable, beneficially popularization and application.
