Description

Precast concrete hollow square pile

Technical field

The present invention relates to a kind of precast concrete hollow square piles, belong to precast concrete hollow square pile technical field.

Background technique

Precast concrete hollow square pile is divided into prestressed concrete square pile, prestressing force according to strength grade of concrete and wall thickness High intensity concrete square pile code name is PC, and prestress high intensity concrete square pile code name is that PHS.PS concrete strengths must not be lower than C60 concrete, PHC strength grade of concrete must not be lower than C80.

PCS and PTC generally use atmospheric steam curing, generally to pass through ability injection in 28 days, and after PHS demouldings To enter that autoclave is steam-cured, and the steam press maintenance through 10 atmospheric pressure, 180 degrees or so, strength grade of concrete is up to C80 from being molded into The shortest time used only needs three, four days.

Currently on the market, industry, civil buildings with it is relatively large number of be prestressed concrete pipe pile, it overcomes in the past The shortcomings that pile-type used and there is own characteristic, but disadvantage is also apparent from: smooth in appearance is rounded, especially as the sassafras stake that rubs In use, it is small with the frictional force of soil, have to increase using the big tubular pole of outer diameter or simply using solid square pile in many engineerings Project cost；The anti-bending strength of thin-wall pipe pile is poor, and the shearing resistance, tensile property of especially pile body are poor, to the basis of building Hidden danger is buried.

So clearly spreading out of information in nearest national prestressed concrete pipe pile investigation meeting, tubular pole is resisted Cut, tensile property is made and provides and tubular pole is used with caution in key project, each expert is square or polygon to appearance in meeting Pile-type is proved and has been looked forward to, it is desirable to which China can think that western developed country is drawn close, and developing appearance is polygon or diameter varied Foundation pile material, pre-stressed concrete hollow square stake be exactly for this purpose and develop.

Summary of the invention

In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of precast concrete hollow square piles.

Precast concrete hollow square pile of the invention, it includes pile top, the first pile body, vertical main reinforcement, lateral tie, docking End, hollow circular hole, the first concrete layer, the second concrete layer, Butt sealing circle, the, are hit at docking pile crown, the second pile body in end Three concrete layers, damp-proof layer and docking recess, pile top right side are provided with the first pile body, are equipped with vertical main reinforcement on the inside of the first pile body And lateral tie, the first pile body right end are fixedly connected with butt end, and docking pile crown, docking pile crown right side are provided on the right side of butt end It is fixedly connected with the second pile body, the second pile body right end, which is equipped with, is hit end, is provided with hollow circular hole, hollow circular hole on the inside of butt end Outside is equipped with the first concrete layer, and the second concrete layer and Butt sealing circle are provided on the outside of the first concrete layer, docks close Third concrete layer is installed on the outside of seal, damp-proof layer is provided on the outside of third concrete layer, docks in pile crown and docking is installed Groove.

Preferably, the bottom pilework is made of pile top, the first pile body and butt end, to pile splicing structure by pile extension Head, the second pile body and hit end composition, in this way setting can effectively guarantee bottom pilework and to the integrality of pile splicing structure and Stability is conducive to improve the integrally-built harmony of the concrete hollow square pile and stability, further guarantees the coagulation The bearing load ability of native hollow square pile improves service efficiency and quality.

Preferably, be provided with vertical main reinforcement and lateral tie in second pile body, setting can guarantee the in this way The integrally-built stability and bearing load intensity of two pile bodies, further keep unity with the first pile body internal structure, Be conducive to improve the concrete hollow square pile entirety bearing load intensity, prevent internal structure from deforming, not only safety and stability but also It is efficiently convenient.
