Method.
Background technique
Pile crown construction method field is being cut at present, because the past is more conventional to the mode for cutting pile crown construction, someone is used
Sledgehammer is directly carried out with handrail-type cutting machine, this may it is careless in destroy the structure of internal reinforcing bar, after causing with
It appears on the stage and holds body welding and occur insecure, cause building lot weak, or even the hidden danger collapsed occur, even crackle, all may
The construction of impression from now on, later period discovery want to make up also bad operation,.Therefore a kind of new section pile crown construction method, operation are needed
While simple, it is most important that the structure of reinforcing bar itself can not be destroyed, guarantee that overall structure is complete.
Summary of the invention
The problem to be solved in the present invention is how to provide a kind of section of pile crown construction, this section of pile crown is primarily directed to a variety of fields
It closes and uses, defect or disadvantage complicated for operation existing for traditional section pile crown mode can either be overcome, and can enhance practical
The function of property, to meet the needs of associated scenario.
To solve the above-mentioned problems, the present invention provides it is a kind of for concrete precast pipe pile cut pile crown construction method,
Prefabricated tubular pile includes framework of steel reinforcement, outer concrete and interior layer concrete, and framework of steel reinforcement is cast in outer concrete and internal layer is mixed
Between solidifying soil；The construction equipment of use includes cutting machine, tube bundle extracting machine, outer layer core pulling cylinder and internal layer core pulling cylinder；Construction method includes
Following steps:
S1, tube bundle extracting machine is erected above prefabricated tubular pile；
S2, ring cutting carried out to prefabricated tubular pile with cutting machine, when cutting does not injure the framework of steel reinforcement in prefabricated tubular pile；
S3, outer layer core pulling cylinder is installed on tube bundle extracting machine, is drilled through by outer concrete of the outer layer core pulling cylinder to prefabricated tubular pile
And it removes；
S4, internal layer core pulling cylinder is installed on tube bundle extracting machine, is drilled through by interior layer concrete of the internal layer core pulling cylinder to prefabricated tubular pile
And it removes；
S5, the residual concrete on prefabricated tubular pile is purged, exposes framework of steel reinforcement.
Preferably, the diameter of outer layer core pulling cylinder is identical as prefabricated tubular pile outer layer diameter in step S3.Convenient for outer layer core pulling cylinder
Outer concrete can be directly corresponded to, framework of steel reinforcement is not injured, and carries out stripping operation.
Preferably, the diameter of internal layer core pulling cylinder is identical as prefabricated tubular pile internal layer diameter in step S4.Convenient for internal layer core pulling cylinder
Layer concrete in can directly corresponding to, does not injure framework of steel reinforcement, and carry out stripping operation.
Preferably, the ring cutting excision that step S2 cutting machine carries out is prefabricated tubular pile outer concrete structure.In this way
The position for setting removed concrete to prefabricated tubular pile convenient for tube bundle extracting machine operates.
Preferably, step S3 can be exchanged with the job order of step S4.Either first strip outer concrete or elder generation
Interior layer concrete is stripped, final purpose is consistent with effect.
It is a kind of for concrete precast pipe pile cut pile crown construction method have it is below the utility model has the advantages that
1. easy to operate, practical function.Only it need to switch ectonexine core pulling cylinder on tube bundle extracting machine, it can be to the ectonexine of prefabricated tubular pile
Concrete is stripped respectively, and process only separates concrete and do not injure framework of steel reinforcement, guarantees the stability of its function.
2. saving labour, fault rate is reduced.The concrete on prefabricated tubular pile can be removed by tube bundle extracting machine, no
It is abolished by force with extra manpower, and reduces artificial caused operation error, it is easy for construction.
