Description
Technical field
The invention belongs to building pile foundation construction field, after being specifically related to a kind of contrary sequence method, plug in steel pipe column vertical locating device.
Background technology
Contrary sequence method has now been widely used in the Foundation Design of the mega projects such as all kinds of highrise building and subway, as permanent support, its steel pipe column is deepened also to become super large overlength along with the increasing of foundation ditch, and more and more higher to the requirement of steel pipe column verticality, difficulty of construction is also increasing.
Existing steel pipe column verticality generally relies on its deadweight or utilizes simple manual adjustment device to control in the underlying process of steel pipe column, but can not designing requirement be reached to the steel pipe column of major diameter, length length at all, even if there is very little off normal on the method steel pipe column top of this traditional control steel pipe column verticality, (caused by perpendicularity deviation) after the amplification of certain length, also larger off normal is produced by steel pipe column bottom, the steel pipe column top off normal 5mm of such as 25 meters long, then the off normal of steel pipe column bottom and the stake heart may reach 125mm.In addition, steel pipe column produces after off normal, and it is long in time limit, costly that the later stage remedies construction processing.
Therefore, how in the work progress of steel pipe column, obtaining accurate verticality, is the technical problem that those skilled in the art make great efforts to solve always.
Summary of the invention
An object of the present invention is to overcome the deficiencies in the prior art, provides a kind of and can plug in steel pipe column vertical locating device after the contrary sequence method of the long verticality of steel pipe column in foundation ditch of large, the length of accurate adjustment diameter, and this apparatus structure is simple and be easy to operation.
For achieving the above object, present invention employs following technical scheme:
Plug in steel pipe column vertical locating device after a kind of contrary sequence method, comprise crane, for suspending two wire rope and the hydraulic press of steel pipe column in midair, the outside at hydraulic press is stretched out in the upper end of described steel pipe column, and the lower end of steel pipe column is uncovered;
This device also comprises the Steel Pipe Column vibrator being with it arranged on and stretching out on the upside of hydraulic press, described vibrator is arranged in pairs, every pair of vibrator all distributes along the axisymmetrical of steel pipe column, and all vibrators are all evenly distributed on all sides of shaft along the ring-type tube wall of steel pipe column;
The lower end shaft of described steel pipe column is laid with disturbance component, and the lower end shaft of steel pipe column is also provided with the breach inside and outside some connection steel pipe columns.
Preferably, described disturbance component is be installed in the holdfast on pipe column lower end shaft.
Preferably, described breach is set to 4 ~ 8, and breach is all uniformly distributed along the ring-type tube wall of steel pipe column.
Further, the lower end shaft of described steel pipe column is also provided with auxiliary positioning frame, described auxiliary positioning frame is made up of some reinforcing bars, described reinforcing bar is all evenly distributed on all sides of shaft along the ring-type tube wall of steel pipe column, the upper end of arbitrary described reinforcing bar is all welded as a whole with steel pipe column, the lower end of all reinforcing bars all welds together, and the welding position of reinforcing bar lower end is in the downside of steel pipe column.
Further, the reinforcing bar of arbitrary formation auxiliary positioning frame is formed by epimere, stage casing and hypomere, the stage casing of all reinforcing bars is distributed in all sides of steel pipe column and all parallels with the axis of steel pipe column, and the stage casing of all reinforcing bars is all on the periphery of line centered by the axis of steel pipe column.
Two of object of the present invention is to provide and a kind ofly utilizes the construction method of plugging in steel pipe column vertical locating device after above-mentioned contrary sequence method, and it comprises the steps:
1), also positioning hydraulic machine is installed;
2) crane of accurately location, is utilized by steel pipe column vertical lifting on hydraulic press, and guarantee on crane for suspend steel pipe column in midair two rope capacities unanimously and be all in tension, thus now steel pipe column is in the vertical state of nature under self gravitation effect;
3), by hydraulic press, steel pipe column press-in is filled with in the installing hole of pile concrete, when face is built close to pile concrete in the bottom of steel pipe column, utilize the clamp device of embracing of hydraulic press that rear clamping is accurately located at steel pipe column top, again hydraulic press is embraced clamp device to decontrol, after steel pipe column is static, the verticality of repetition measurement steel pipe column and position location, clamp after meeting the demands again, utilizes the pressure of hydraulic press to be inserted by steel pipe column in the pile concrete before initial set;
4), when the compression distance of steel pipe column bottom reaches designing requirement, again decontrol hydraulic press and embrace clamp device, start the symmetrical vibrator being placed on steel pipe column week side simultaneously, steel pipe column is made to swing with vertical adjustment again by vibrator, after the verticality of repetition measurement steel pipe column and position location meet the demands, steel pipe column can be fixed; Otherwise utilize hydraulic press and vibrator again to carry out vertical adjustment and location to steel pipe column, repeat above-mentioned work until the verticality of steel pipe column and location meet the demands.
Beneficial effect of the present invention is:
1), the lower end of steel pipe column is set to uncovered by the present invention, and breach and disturbance component is laid with on the lower end shaft of steel pipe column, then in the construction and installation process of steel pipe column, when steel pipe column inserts pile concrete from top to bottom, pile concrete enters steel pipe column inside, to avoid the situation that steel pipe column can not insert in time because of pile concrete initial set by the breach on the uncovered of pipe column lower end and shaft; Disturbance component on pipe column lower end shaft then plays the effect of stirring pile concrete, to stop concrete coagulation and to enable concrete successfully enter steel pipe column inside through breach.
The said structure of steel pipe column significantly can reduce Cat-in resisting force in the process of construction and installation, thus effectively improves operating efficiency, reduces the construction period.
2), the present invention is also provided with auxiliary positioning frame on the lower end shaft of steel pipe column, auxiliary positioning frame is that halter shape is around on the lower end shaft of steel pipe column, it has following two effects: one, can ensure that steel pipe column inserts in concrete process from top to bottom, hole and stake holes can not be mounted opposite and produce larger inclination, thus after ensureing contrary sequence method, insert substantially overlapping of steel pipe column and both stakes center; Its two, auxiliary positioning frame is surrounded by the reinforcing bar of strip, has certain flexibility, then it is when inserting concrete with steel pipe column, even if off normal appears in steel pipe column, also can not cause and destroy pile wall because rigidity is excessive, so that the phenomenon causing the soil body to cave in occurs, thus ensure that the safety of construction.
In addition, auxiliary positioning frame also has the advantage making simple, with low cost and easy construction.
3), adopt vertical locating device in the present invention and construction method, be easy to operation and vertical adjustment, and control accurately, to be particularly suitable for the construction and installation of the steel pipe column of major diameter and length.
