Abstract
The invention discloses a stripping method of a 55m PHC tubular pile, which includes the following steps: 1. the bolts on a matchboard of an overall steel mold of the whole PHC tubular pile are removed, and then an upper die of the steel mold is lifted away; 2. a plurality of semi-round stripping roller frames are arranged, and each stripping roller frame corresponds to a roller on a lower die; 3. the pile and the lower die are rotated, the lower die is led to face upwards, and the PHC tubular pile is supported by a semi-round stripping roller bracket; 4. the lower die and the stripping roller frame are separated and the lower die is lifted away; 5. the whole PHC tubular pile is lifted to a storage yard. The invention has the advantages that: the method integrates a shoulder pole beam, a wire rope lifting tool and the stripping roller frame, thus simplifying the complex stripping process, and the PHC tubular pile is not impacted during the whole stripping process; the operation is safe during the whole stripping process and the efficiency is high.
Description
Technical field:
The present invention relates to the release method of PHC pile tube, particularly a kind of release method of 55mPHC pile tube.
Background technology:
Nineteen twenty has invented centrifugal process by Australian W.R HUME and has made the concrete product production technology, Japan has introduced this technology in next year, be used to make reinforced concrete pipe pile, began to make centrifugal concrete pile (Reinforced Spun High Stregth Concrete Piles is called for short the PC stake) in 1934.1967-1970 Japan has developed prestressed high strength concrete centrifuge tube stake (Pretesioned SpunHigh Stregth Concrete Piles is called for short the PHC pile tube).The PHC pile tube is the Architectural Equipment that extensively is employed at present in the heavy construction construction.The concrete-pile that uses in Japan almost is the PHC stake at present, this external American-European countries, as the U.S., France, Germany, Italy, the former Soviet Union, though and the start-up time of every country in Southeast Asia is later, but development is very fast closely during the last ten years, the pile tube of especially big specification,, its output and product specification are all above Japan.
China just begins to produce centrifugal concrete pipe (RC stake) as far back as nineteen forty-four; The sixties, developed prestressed reinforced concrete pipe pile (PC stake), and produced the PC stake of Ф 400 and Ф 550 in batches, the seventies development and production the post stressed concrete pile tube; Developed pretensioned prestressing high-strength concrete tubular pile (PHC stake) and pretensioning prestressed concrete thin-wall pipe pile (PTC stake) the late nineteen eighties, and begun to apply.
In recent years along with the requirement of construction is more and more higher, the pile tube length that water project uses is more and more longer, yet prior art can only be accomplished 50m for single-unit pile tube length, and generally be 30m, the just necessary pile extension of stake that surpasses 30m so, because pile extension can bring a lot of problems, particularly pile breaking phenomenon often takes place in PHC stake injection process, as dragon's pool port, Nanjing two, in the third stage of the project, design φ 800PHC pile tube is driven piles in December, 2005, in the piling process, serious pile breaking phenomenon has taken place, almost all interrupted, and all occurred near the joint, adopted φ 1000 pile tubes that broken pile still takes place near joint afterwards.According to statistics, PHC pile tube broken pile of 70% in the piling process occurs near the joint.Factors such as concrete process for sinking, geological conditions make some difference to broken pile, but the distinctive joint construction of PHC pile tube and this type of broken pile have bigger relation.
The release method of PHC stake at present generally is earlier patrix to be laid down, and utilizes loop wheel machine rotation counterdie then, and the PHC stake is rolled out from counterdie, and such release method is very easy to cause the damage of PHC stake and punching block.External also have a release method that adopts vacuum cup, after patrix is laid down, with vacuum cup with the PHC pile tube hold, handling is to the pile tube stockyard, this method is more loaded down with trivial details, cost is also high.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of release method of 55mPHC pile tube, and this release method can successfully successfully take off the 55mPHC pile tube from punching block.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of release method of 55mPHC pile tube is characterized in that, comprises the steps:
1, earlier the Bolt dismantling on the matchboard in the whole punching block of whole PHC pile tube is got off, hang away the patrix in the punching block;
2, several demoulding turning rolls are installed, each demoulding turning rolls is corresponding with the running wheel on the counterdie;
3, rotation pile tube and counterdie make counterdie up, and the PHC pile tube is supported on the demoulding turning rolls;
4, counterdie and demoulding turning rolls are separated, hang away counterdie;
5, at last whole PHC pile tube hung the stockyard.
The advantage of the inventive method is: this method oversimplifies loaded down with trivial details in the past knockout course in conjunction with shoulder pole girder and steel wire rope suspender and demoulding turning rolls, and whole knockout course, the PHC pile tube can not impacted, and is fool proof in the operation in the whole knockout course, and the efficient height.

The specific embodiment:
Further specify the present invention below in conjunction with accompanying drawing.
As Fig. 1-shown in Figure 5, a kind of release method of 55mPHC pile tube comprises the steps:
1, earlier the Bolt dismantling on the matchboard in the whole punching block of whole PHC pile tube is got off, hang away the patrix in the punching block;
2, several demoulding turning rolls 1 are installed, each demoulding turning rolls 1 is corresponding with the running wheel 21 on the counterdie 2;
3, rotation counterdie 2 makes counterdie 2 overturn 180 ° up, and left-hand thread is on PHC pile tube 3;
4, counterdie 2 and demoulding turning rolls 1 are separated, hang away counterdie 2;
5, at last whole PHC pile tube 3 hung the stockyard.
Referring to Fig. 6, Fig. 7 and Fig. 8, demoulding turning rolls 1 comprises running wheel 11 and two matchboards 12, and running wheel 11 is half garden shape, two ends with respectively with the welding of two matchboards 12, on two matchboards 12, offer bolt slot 121.
More than be one of embodiments of the present invention,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize purpose of the present invention equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the present invention.
