Description
Technical field
The present invention relates to cutting prefabricated tubular pile method field, in particular to one kind cuts the reservation of concrete precast pipe pile pile crown
Reinforcing bar method.
Background technique
At present in cutting prefabricated tubular pile method field, because the mode of any excess concrete of excision prefabricated tubular pile is mostly now
Manpower sledgehammer is abolished or hand-held cutting machine, although reducing human cost etc., all exists and destroys internal bar construction
Risk, this effect of risk is changeable, seriously may cause that building structure is unstable, influences the peace of people's lives and properties
Entirely, in order to avoid there is such case, a kind of new cutting prefabricated tubular pile method is needed, while being easy to use, and is not destroyed
Internal bar construction makes monolithic architecture secure, reduces unnecessary hidden danger.
Summary of the invention
The problem to be solved in the present invention is how to provide a kind of cutting prefabricated tubular pile method, which is mainly needle
A variety of occasions are used, deficiency existing for traditional cutting mode or disadvantage complicated for operation can either be overcome, and can
Enhance the function of practicability, to meet the needs of associated scenario.
To solve the above-mentioned problems, concrete precast pipe pile pile crown is cut the present invention provides one kind retain reinforcing bar 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, veneer sawing machine and small saw blade；Veneer sawing machine is located at the top of prefabricated tubular pile；Stake
Head retain reinforcing bar method the following steps are included:
S1, the top that veneer sawing machine is mounted on to prefabricated tubular pile；
S2, ring cutting is carried out to prefabricated tubular pile with cutting machine, framework of steel reinforcement is not injured in cutting process；
S3, small saw blade is installed on veneer sawing machine, ring cutting is carried out by interior layer concrete of the small saw blade to prefabricated tubular pile, and not
Injure framework of steel reinforcement；
S4, the outer concrete of well cutting and interior layer concrete are pulled out or is knocked out, and do not damaged in prefabricated tubular pile
Framework of steel reinforcement；
S5, residual concrete on prefabricated tubular pile is purged.
Preferably, framework of steel reinforcement can be to top cushion cap or lightning-protection system progress is corresponding welds.Design can guarantee structure in this way
Globality, reduction there is error in architectural design.
Preferably, in step S3 small saw blade diameter be less than prefabricated tubular pile in layer concrete diameter.Convenient for small saw blade into
Enter the boring part of prefabricated tubular pile, and adjust angle and position, carries out cutting operation.
Preferably, the 2 outer concrete structure of prefabricated tubular pile for being for the ring cutting excision that step S2 cutting machine carries out.Only
Outer concrete is cut, while avoiding damage to framework of steel reinforcement, is convenient for breaking concrete.
Preferably, outer concrete is cut in step S2 ~ S3 and the position of interior layer concrete is corresponding.It avoids because of cleavage
Difference is set, the case where stripping appearance is led to not.
Preferably, step S2 can be exchanged with the job order of step S3.The two exchange job order has no effect on finally
Purpose, therefore layer concrete in no matter first cutting outer concrete or first cutting, effect is all consistent.
One kind cut concrete precast pipe pile pile crown retain reinforcing bar method have it is below the utility model has the advantages that
1. it is easy to operate, avoid reinforcing bar from destroying.Only need veneer sawing machine and cutting machine respectively to the inside and outside layer concrete of prefabricated tubular pile
It is cut, then is pulled out, and internal framework of steel reinforcement is not destroyed, guarantee the integrality of framework of steel reinforcement.
2. manpower is saved, it is easy for construction.The coagulation of prefabricated tubular pile can be removed by the operation of veneer sawing machine and cutting machine
Soil is abolished without excessive manpower, greatlys save human cost and time cost, and easy for construction, reduces manual operation
Fault influences engineering.
