Abstract
(B, ) the utility model relates to a fields such as city high -rise building, high dynamic load's high -speed railway and abutment basis, the utility model is realized through the follow technical scheme: in dig method prestressed concrete pipe pile constitutes characterized by by prestressing steel and concrete: install prestressing steel below the end cover, install a core prestressing steel again in prestressing steel's inside, install the spiral muscle in prestressing steel's outside, have the concrete in the pouring of the inside of prestressing steel and spiral muscle, install the stake point in prestressing steel's bottom and manage, owing to the utility model discloses a be the structure of end cover, prestressing steel and spiral muscle, deposit concrete tubular pile like this, just can play hinder split, operation requirement such as anticorrosive, impervious, reinforcing, antidetonation, long service life. (B, )
Description
Technical field
The present invention relates to the fields such as urban skyscraper, the high-speed railway of high dynamic load and abutment basis.
Background technology
It is known that, high-speed railway is currently a flourish industry, pick method pile tube in its abutment base growth, it it is a highly desirable product, its prospect is immeasurable, city middle-high building, and the application of current PHC pile tube is almost blank, middle pick method pile tube is exactly these prefabricated components filled in the blanks undoubtedly, and its prospect is fine.
Utility model content
The purpose of this utility model is to solve above-mentioned problem, and a kind of technique provided is simple, anticorrosion, impervious, penetration capacity strong, the middle pick method prestressed concrete pipe pile of antidetonation, long service life.
This utility model is achieved in that middle pick method prestressed concrete pipe pile, it is made up of deformed bar and concrete, it is characterized in that: be mounted below deformed bar at end cap, a core deformed bar is installed again in the inside of deformed bar, in the outside of deformed bar, spiral bar is installed, it is cast with concrete in the inside of deformed bar and spiral bar, in the bottom of deformed bar, pile top pipe is installed.
The concrete being stirred is poured in mould after plugging and pounding closely knit molding by this utility model, enters steam curing.
The beneficial effects of the utility model are in that: what adopt due to this utility model is the structure of end cap, deformed bar and spiral bar, so pours into a mould concrete tubular pile, just can play resistance split, anticorrosion, impervious, enhancing, antidetonation, the instructions for use such as long service life.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is Fig. 1 " A-A " sectional view.
In figure, each label declaration is as follows:
1, end cap, 2, deformed bar, 3, stake core deformed bar, 4, spiral bar, 5, concrete, 6, stone, 7, pile top pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
This utility model is dug method prestressed concrete pipe pile, its manufacturing process strictly operates by technological specification, reinforcing bar adopts full-automatic fixed-length cutting machine blanking, steel reinforcement cage adopts full-automatic roll welding to become cage, undertaken steel reinforcement cage assembling, stretch-draw concrete adopts full-automatic computer dispensing, then pours in mould by concrete, after plugging and pounding vibratory compaction molding, entering the steaming maintenance of steam-cured pond, after a few hours, the demoulding enters back into high temperature steam curing.
It is 800 millimeters that the steel plate that end cap 1 of the present utility model adopts thickness to be 20 millimeters is processed into diameter, the deformed bar 2 that 6 diameters are 30 millimeters is welded on below end cap 1, the stake core deformed bar 3 that 6 diameters are 20 millimeters is welded on below end cap 1, the spiral bar 4 that diameter is 12 millimeters is welded on above deformed bar 2, the stone that stone 6 selects diameter to be 16 millimeters, concrete 5 adopts strength grade to be not less than the portland cement of 42.5, admixture (breeze and levigate sand or silica flour), sand, rubble and what high efficiency water reducing agent was made into by corresponding proportion, the steel plate processing and fabricating that pile top pipe 8 selects thickness to be 16 millimeters, its effect is easily accessible in soil property exactly.
After the concrete 5 being stirred is poured in mould molding by centrifugation by this utility model, entering room temperature steam curing, after a few hours, the demoulding enters back into high temperature steam curing.The instructions for uses such as prestress high intensity concrete with stake point pile tube just can play anticorrosion, impervious, penetration capacity strong, antidetonation, long service life.
Middle pick method refers to pick base expanding and base expanding construction method in prefabricated pile basis, this new and high technology is based on the advanced construction technology of international popular, simultaneously energy-conserving and environment-protective, pile material is damaged less, reduce casting, reduce the soil compaction on neighboring buildings and affect, pile foundation industry is caused to show great attention to widely, the particularly skyscraper in city, this engineering method can meet the pile foundation of high resistance to plucking requirement.And it is not matched in the prefabricated pile of this engineering method so far specially, only use PHC pile tube alternative, and the joint form of the extraction-resistant behavior of PHC stake and stake all fails to fully meet middle pick method requirement, this project is with regard to this problem, work out the pile tube giving full play to middle pick method advantage, make this class pile foundation engineering method and tubing, be suitable for urban skyscraper demand, be also suitable for the requirement on the high-speed railway of high dynamic load, abutment basis.
In sum, this utility model bearing power increase, easy construction is reliable, can in different area uses.
