Description
Technical field
The present invention relates to the realm of building construction, and in particular to a kind of to carry out what cushion cap was connect with pile foundation by attachment device
Construction method.
Background technique
(explanation: fabricated construction is the various components of engineering in factory's pre-production to fabricated construction, and construct Shi Xian
Field carries out assembly connection, and the process for not needing in-site pouring cement shortens the construction time, guarantees construction quality) it is cast-in-place with tradition
(explanation: being traditional arrangement and method for construction to structure, needs to make the processes such as template, reinforcing bar and carries out cement grouting, construction time
Long, work surface is big) it compares, the emphasis of quality control is the processing of each primary structure member connecting node.Currently, municipal bridge work
Connection between journey superstructure, between superstructure and pier stud comparative maturity, and for pile foundation and prefabricated cushion cap
Connection, is related to less, especially under the complex environment of city, how around avoiding pipeline, Rapid Implementation pile foundation
It is always difficult point and hot spot in engineering with the connection of prefabricated cushion cap.The present invention has devised small straight specifically for city overline bridge
The conversion equipment that diameter pile foundation is connect with prefabricated cushion cap realizes the quick connection on Small Diameter Pile basis and prefabricated cushion cap.
Summary of the invention
In view of the deficiencies of the prior art, carry out what cushion cap was connect with pile foundation by attachment device the present invention provides a kind of
Construction method is effectively shielded from complicated underground utilities using Small Diameter Pile, avoids the case where destroying underground pipeline system hair
It is raw, cushion cap is carried out using connection transfer device and is connect with pile foundation, can solve the cause of the position deviation as caused by construction of prefabricated piles
Stake is set to dock difficult problem with cushion cap reserving hole, it is only necessary to according to the size of cushion cap, make conversion equipment, not need to examine

Layer surface is laid with the steel plate outline border prefabricated according to cushion cap length and width dimensions, and cushion cap is welded to connect at four ends angle of steel plate outline border
Steel pipe；
S2 carries out inserting piling prefabricated pile using static pressure force method, prefabricated stake is squeezed by machinery, prefabricated pile reserves
The certain length in ground (generally 600-800mm)；
S3, after placing the prefabricated steel plate outline border for having welded joint steel pipe, with prefabricated steel plate and each stake top, company
Connect the steel-pipe welding of cushion cap, the prefabricated steel plate size is consistent with cushion cap top surface size, aperture on the steel plate, orifice position with
The distributing position of stake and steel pipe matches, and the size of aperture is matched respectively at stake diameter size, the size of joint steel pipe diameter.
S4 makes prefabricated cushion cap in factory according to the cushion cap size of design, prefabricated cushion cap include grout hole, extravasating hole and
Grouting Pipe, there are location holes for prefabricated cushion cap four positions for holding angle to be correspondingly connected with steel pipe, position pore size and joint steel pipe size
It is adapted；
S5, the prefabricated cushion cap of in-site installation, the location hole of prefabricated cushion cap entangle joint steel pipe outstanding, from default grout hole
It is quickly connected by Grouting Pipe grouting.
The case where further, the prefabricated pile is Small Diameter Pile, is explored in inserting piling prefabricated pile according to address early period,
The distributing position and overline bridge load of pipeline determine the position of inserting piling pile.
Further, the height that the height of the steel plate outline border reserves ground with prefabricated pile matches.
Further, in the step S3, after the steel plate welding of the steel plate outline border provided with joint steel pipe and aperture, shape
The conversion equipment being connect at cushion cap with stake.
Further, comprising the following specific steps prefabricated cushion cap is sling in the step S5, prefabricated cushion cap is reserved
The part of the prominent steel plate of aligned joint steel pipe, the decline of prefabricated cushion cap the joint steel pipe of protrusion cover completely
In reserved hole, then carries out grouting construction and prefabricated cushion cap and prefabricated pile are linked into an integrated entity.
Further, the steel pipe that cushion cap is welded to connect at four ends angle of steel plate outline border, length should compare prefabricated pile
Reserve the long 300-500mm of length on ground.
A kind of beneficial effect carrying out the construction method that cushion cap is connect with pile foundation by attachment device provided by the invention exists
In: it is effectively shielded from complicated underground utilities and carries out pitching pile, avoid the case where destroying underground pipeline system generation；It is suitable for
The bridge underground construction of current city is built；Cushion cap is carried out using connection transfer device to connect with pile foundation, can solve due to pre-
Position deviation caused by pile driving construction processed causes stake to dock difficult problem with cushion cap reserving hole, it is only necessary to according to the big of cushion cap
It is small, conversion equipment is made, without the concern for the position of prefabricated pile, is conducive to the standardization batch production of cushion cap, cushion cap exists
Factory's pre-production after cushion cap is connect with pile foundation by converter device, withouts waiting for the age of concrete, can at once into
The installation of row day pier column, greatly reduces the construction time.
