Description
Technical field
The present invention relates to a kind of prefabricated RPC tube pile structure of Alveolus type type and its construction methods, belong to field of civil engineering.
Background technique
Currently, the effect of pile foundation structure is significant either in science of bridge building or architectural engineering, valence is used with biggish
Value.It is generated in very big time however, the larger sedimentation of pile foundation, especially differential settlement will lead to hyperstatic structure originally
Power causes the cracking of structure even to destroy；Especially in soft clay area, the anti-settling ability to pile foundation has higher requirement.For rubbing
Wiping type pile foundation, it usually needs increase that stake is long to obtain biggish frictional resistance, cost is thus considerably increased, on the water surface
Building, pile foundation are easier to be influenced by other effects such as underground water and pull up destruction, can also make to superstructure
At serious damage, and the maintenance correction in later period is costly, difficulty of construction is big.Solid square is generally used in traditional prefabricated pile
Stake, tubular pole, intensity difference can not provide very big mechanical snap power and frictional resistance.Meanwhile the sedimentation of existing stake or pulling up meeting
Cause the destruction of superstructure, and Piles for Friction Piles usually requires to increase that stake is long guarantees enough soil resistances, so as to cause make
The increase of valence.
Meanwhile for it is some by horizontal cross act on based on science of bridge building in, pile foundation is under horizontal direction load action
Easily occur cracking, reinforcement yielding and destroy.At this time, it may be necessary to biggish lateral drag is provided by the lateral stiffness for increasing stake,
Existing common practice is the sectional area for increasing pile foundation, which not only makes pile foundation clumsy, is not easy hammer driven construction；
Meanwhile also with substantially increasing pile foundation cost expense.The above various problems of pile foundation bring, to the power of pile foundation structure
It learns performance and proposes higher requirement, not only to solve settlement issues, while the not easy to crack, reinforcing bar under horizontal direction load action
Yield failure problem proposes higher requirement to bridge's design teachers.
Summary of the invention
The technical problem to be solved by the present invention is to make upper part knot for the above ordinary pile foundation plinth differential settlement
Structure generate two second inner forces and its by action of horizontal lateral effect is lower and the problems such as cracking destruction, provide a kind of novel Alveolus type type
Prefabricated RPC tube pile structure and its construction method.
In order to solve the above technical problems, specific embodiments of the present invention are: a kind of prefabricated RPC tubular pole knot of Alveolus type type
Structure, including the prefabricated pile body structure equipped with steel reinforcement cage made by RPC, interior, the outside of the prefabricated pile body structure is integrally formed
Have it is multiple lay along axial to improve the concrete ribs of prefabricated strength of pile body, the inner surface of the prefabricated pile body structure and outer
Surface is painted with waterproof coating layer.The RPC material have rigidity and intensity are big, bearing capacity is high, it is not easy to crack, corrosion etc. it is excellent
Gesture.
Further, the concrete rib is equidistantly laid, and the concrete rib is by the top surface one of prefabricated pile body structure
Directly extend to the bottom surface of prefabricated pile body structure.
Further, the prefabricated pile body structure includes pile body and stake bottom, and the stake bottom is in back taper.
Further, the cross section of the concrete rib is trapezoidal.
Further, the waterproof coating layer is polymer cement-base waterproof coating composition.
Further, the steel reinforcement cage is uniformly distributed for longitudinal stress muscle, stirrup and frame force rib and binds.
A kind of prefabricated RPC tube pile structure construction method of Alveolus type type, specifically includes the following steps:
(1) the prefabricated of mold is poured:
RPC tube pile structure mold is made according to Practical Project Demand Design；
(2) precast reinforced cage:
According to the stress performance of RPC tube pile structure, design parameter etc. determine needed for reinforcing bar, by required longitudinal stress muscle,
Stirrup and frame force rib etc. are bound into steel reinforcement cage；
(3) RPC tube pile structure pours:
The steel reinforcement cage bound is put into and is poured in mold, RPC is poured into mold, the mold for completing to pour is put into
Centrifugal forming is carried out on centrifuge；
(4) maintenance and the brushing of water-repellent paint:
Mold is removed, the steam-cured of later period is carried out to RPC tube pile structure；After the completion of RPC tube pile structure is steam-cured, RPC is managed
Pilework outer surface surrounding and inner surface carry out the spary of water-repellent paint；
(5) it drives piles:
After the completion of the maintenance of RPC tube pile structure and the brushing of water-repellent paint, RPC tube pile structure is passed through into pile hammer and stake top
Connection, installation, which is sling, to be pushed down on, and prefabricated RPC tube pile structure is made quickly to sink.
Compared with prior art, the invention has the following advantages: the present invention is simple, rationally, intensity is high, greatly for design
Ground improves the problem of pile foundation settlement, using active concrete (RPC) good fluidity, so that pile foundation structure is easily molded, simultaneously
Intensity, the rigidity of RPC is big, so that prefabricated RPC tubular pole outer surface concrete rib has high intensity, can bear biggish soil around pile pressure
Power is destroyed without being extruded, and can preferably be provided mechanical snap power and frictional resistance, be greatly improved the stress of prefabricated pile body structure
Performance.Meanwhile the diameter of stake is not only reduced, and reduce the dosage of the construction materials such as concrete, reinforcing bar, realize material cost
Saving.In addition, can be prefabricated pile body knot in the outer surface of prefabricated pile body structure and the composite water-proof coating of inner surface brushing
The concrete rib of structure periphery provides certain protective effect.
In conclusion RPC tube pile structure provided by the invention is simple, intensity is high, significantly improves asking for pile foundation settlement
Topic, it is good using active concrete flowability, intensity and toughness is big and bearing capacity is high the advantages that so that prefabricated RPC tubular pole outer surface tooth
Slot rib have high intensity, can bear biggish soil around pile pressure without be extruded destruction, can preferably provide mechanical snap power with
Frictional resistance greatly improves the vertical and horizontal direction stress performance of RPC tubular pole.Meanwhile in the outer surface of stake and inner surface brushing
Composite water-proof coating can provide certain protective effect for the RPC tooth socket rib of stake periphery.RPC tubular pole provided by the invention can
It is prefabricated in the factory, scene of transporting to after the completion of prefabricated carries out lifting and squeezes into, and has the characteristics that easy for construction, save the cost.
