Description
Technical field
It is a kind of PHC tubular pile heads method for repairing damage specifically the present invention relates to a kind of damaged reparation of the pile tube in civil engineering.
Background technology
At present, method for repairing and mending generally cuts off damaged part post-grouting filler after tubular pile head breakage, but this kind of method has many deficiencies, and one is increased pile tube casting effect, surrounding stake displacement increase；Second, repair time is grown, then difficulty of construction increase；Third, rehabilitation expense is higher.Fig. 1 is the schematic diagram of known damaged pile crown.
Chinese patent CN105274986A discloses a kind of pile sinking pile crown method for repairing damage of PHC pile tubes on January 27th, 2016, including following steps：1）Cut stake；2）New stake end plate is installed；3）Basetray is installed；4）Stake outer wrapping plate is installed；5）Rubble and sand are inserted；6）Mix and blend thing pours into；7）The plate surface polishing of stake termination；8）Secondary piling construction.The lower end of blast pipe 5 is first passed vertically through basetray 4 and is welded and fixed by the technical scheme as basetray 4, steel pipe using steel plate in repairing as blast pipe 5.This technical scheme is although make the pile sinking pile crown of PHC pile tubes is damaged to repair, but problem is following, basetray therein has shut the original hollow-core construction of pile tube, is only substituted with tiny blast pipe 5, increase piling construction pile inner air pressure, thus derive a series of construction problem.
Therefore the pile sinking pile crown method for repairing damage of known PHC pile tubes there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of the present invention, it is to propose a kind of PHC tubular pile head method for repairing damage for keeping the original hollow-core construction of pile tube.
It is a kind of using outer steel mould simple in construction and the PHC tubular pile head method for repairing damage of interior punching block it is another object of the present invention to propose.
To achieve the above object, technical solution of the invention is：
A kind of PHC tubular pile heads method for repairing damage, it is characterised in that comprise the following steps：
A, damaged pile crown is amputated by design requirement；
B, outer steel mould, interior punching block and ring flange are made according to the internal diameter of damaged pile crown and external diameter, the outer steel mould of making and interior punching block is fitted in pile body outer wall and inwall respectively, the gap between outer steel mould and pile body outer wall, interior punching block and pile body inwall is blocked with cement mortar；
C, mixture of epoxy resins is filled into the space that outer steel mould and interior punching block surround；
D, the ring flange of making and outer steel mould and interior punching block upper end are welded and fixed, complete the damaged reparation of PHC tubular pile heads.
The PHC tubular pile heads method for repairing damage of the present invention can also be further achieved by the following technical measures.
Foregoing method, wherein the interior punching block length >=400mm.
Foregoing method, wherein outer steel mould length >=600mm.
Foregoing method, made wherein the outer steel mould, interior punching block and ring flange are steel plate.
After adopting the above technical scheme, the PHC tubular pile head method for repairing damage of the present invention has advantages below：
1st, outer steel mould and interior punching block prosthetic device are simple in construction, easy to make；
2nd, pile crown breakage repairing quality is safe and reliable, and restorative procedure is workable；
3rd, original hollow-core construction is kept, does not increase piling construction pile inner air pressure.
