Description
Technical field
The utility model belongs to science of bridge building field, connects more specifically to a kind of low spatial segmentation pile pulling pile crown
Connection device.
Background technique
Current more and more engineering constructions are supported using steel-pipe pile as temporary base, are even more big especially in bridge construction
Amount uses steel-pipe pile as the basis of temporary construction trestle.For the steel-pipe pile that these are driven underground, if be not pulled out not
It only will cause the serious waste of resource, it is also possible to pollute the environment, so can all select in engineering in most engineerings
Steel-pipe pile is extracted after main body completion and is reused.However it is limited sometimes by factors such as the depth of water, landform, headroom, nothing
Method is extracted steel-pipe pile using conventional effective method.Steel-pipe pile extraction especially for low spatial needs to pull out whole stake segmentation
Out, in this case originally just reduced steel-pipe pile recycling value, if also need at every section of pile crown into
The processing such as row aperture connect vibration, rise and the equipment such as pull out and will more damage steel-pipe pile.
Summary of the invention
To overcome defect of the existing technology, the utility model provides a kind of low spatial segmentation pile pulling pile crown connection dress
It sets.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of low spatial segmentation pile pulling pile crown attachment device is designed, including covering the jointing in steel-pipe pile upper end, institute
It states jointing to be made of steel plate and in rounded shape, the jointing inner wall is uneven；The jointing is set with vibration
It is standby with above pull out equipment and connect.
Preferably, the jointing is formed by connecting by four same circular arc clamps, the arc of four circular arc clamps
Degree is less than 90 °.
Preferably, the radian of four circular arc clamps is 85 ° ~ 89 °.
Preferably, the both ends of four circular arc clamps are the connecting plate that extends outwardly, and 5 are offered on the connecting plate
Hole, wherein 4 holes are located at the endpoint of square, remaining 1 hole is located at the center of square, and bolt passes through adjacent connection plates
4 holes four circular arc clamps are connected to become an entirety.
The utility model compared with prior art, has the advantages that
The utility model is suitable for the steel-pipe pile of piles with different diameter, can be set in jointing according to the stake diameter of pile pulling
Diameter, it is adaptable；The attachment device is applicable not only to pile crown, is also adapted for mount on any position of stake.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the top view that low spatial is segmented pile pulling pile crown attachment device；
Fig. 2 is the left view that low spatial is segmented pile pulling pile crown attachment device.
In figure: 1- circular arc clamp；2- bolt；3- steel-pipe pile；4- preformed hole.
Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Figs. 1-2, the utility model provides a kind of low spatial segmentation pile pulling pile crown attachment device, includes and covers in steel pipe
The jointing of 3 upper ends of stake, jointing are made and in rounded shape of steel plate, and jointing inner wall is uneven；Jointing
With vibratory equipment and above equipment is pulled out to connect.Wherein, jointing is formed by connecting by four same circular arc clamps 1, four circular arcs
The radian of fixture 1 is less than 90 °.Preferably, the radian of four circular arc clamps is 85 ° ~ 89 °.The both ends of four circular arc clamps 1 are
Extend outwardly connecting plate, and 5 holes are offered on connecting plate, wherein 4 holes are located at the endpoint of square, remaining 1 reserved
Four circular arc clamps are connected to become an entirety in the center of square, 4 holes that bolt 2 passes through adjacent connection plates by hole 4, in advance
Box out 4 for jointing with above pull out equipment and connect.
The application process of the utility model is as follows: before pile pulling operation, circular arc clamp 1 being connected to become one by bolt 2
A complete jointing covers on pile crown, and tightening bolt 2 makes jointing tightly wale steel-pipe pile 3.Then by vibratory equipment
It is clipped on the connecting plate of jointing, vibrates steel-pipe pile 3.Be connected and fixed by preformed hole 4 after vibration and pull out equipment, start on pull out
Steel-pipe pile 3.After a distance arrival headroom upper limit will be pulled out on steel-pipe pile 3, steel-pipe pile 3 is cut at a certain distance from away from the water surface,
Attachment device disassembly is mounted at following pile crown again, repeats that whole pile is caused all to extract directly with this.
The embodiments of the present invention are described above in conjunction with attached drawing, but the utility model is not limited to
The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
