Abstract
The invention relates to a pile-sinking method, in particular to a pile-sinking method in water area for a PHC tubular pile. The pile-sinking method for the PHC tubular pile is characterized in that the method comprises the following steps of: pile-driving preparation, wherein, the structure, the size, the weight and the underground length of the PHC tubular pile as well as geological conditions and meteorologic conditions at the place for pile sinking are analyzed, and pile-sinking equipment is selected; pile hoisting, wherein, the length of the PHC tubular pile is L, hoisting points of the pile hoisting are designed at the positions which are respectively 0.105L, 0.328L, 0.672L, and 0.895L from the bottom end; pile insertion; pile sinking, wherein, the location of the pile sinking takes the control of a theodolite as a major mode and GPS debugging as an auxiliary mode at the beginning stage, and takes GPS position as a major mode after the normal pile sinking; adopting high strength steel as driving, and adopting corrugated paper to replace the pile; and pile stabilization, wherein, the driven pile is provided with a framing scaffold. The method can better solve the phenomena such as pile top breakage, pile body cracks, overlarge pile top deviation, pile breakage and so on, caused by the prior pile-sinking method.
Description
Technical field
The present invention relates to a kind of pile-sinking method, particularly a kind of PHC pile tube pile-sinking method.
Background technology
Phenomenons such as crack, stake top off normal are excessive, broken pile appear in present PHC pile tube some qualitative problems of ubiquity in pile driving process as pile top break, pile body.
Summary of the invention
The object of the present invention is to provide a kind of PHC pile tube pile-sinking method waterborne, solve the problems referred to above that exist in the present pile driving process.
The present invention solves the problems of the technologies described above by the following technical solutions:
A kind of PHC pile tube pile-sinking method waterborne is characterized in that, may further comprise the steps:
Piling is prepared, and analyzes structure, size, weight, the length of burying of PHC pile tube, and the geological conditions at pile sinking place, meteorological condition are selected pile sinking equipment;
Hang stake, the PHC pile tube is long to be L, and the suspension centre design of hanging stake is at distance bottom 0.105L, 0.328L, 0.672L, 0.895L place;
Pitching pile;
Pile sinking, pile sinking are positioned at the incipient stage and are controlled to be main, GPS debugging with transit, orientate the master as with GPS behind the normal pile sinking; Adopt high-strength steel to do to adopt corrugated paper for pile for beating;
Steady stake is to the good waling of having accomplished fluently of pile holder.
Further, wave height less than 0.8 meter, do not influence under the ambient conditions that the steady and anchor hawser of boats and ships pools tightened up and got out of the way the anxious anxious ebb current that rises and carry out pile sinking.
Select different dollies for use, the situation sinking quality of pile that all the other conditions are identical is as follows:
| The pile top break situation | Pile top break | Crack, stake top | Angle, length 〉=10cm are split in the stake top | Stake top spoilage |
| Flitch dolly (amounting to 80 of pile sinking) | 2 | 1 | 8 | 13.8％ |
| Strawboard dolly (amounting to 80 of pile sinking) | 0 | 2 | 6 | 10％ |
| Corrugated paper dolly (totally 280) | 0 | 0 | 5 | 5.4％ |
Adopt the stake top of corrugated paper as dolly, pile quality is significantly better than the pile sinking quality that adopts conventional dolly.Because, using pile monkey of the same race and when beating, the size of dolly stiffness, decision when hammering, the length of hammer and stake time of contact and a hammering size of passing to.Stiffness hour, time of contact is long, and the wavelength of stress wave is big, and the hammering stress of passing to stake is little.Corrugated board is owing to exist the corrugation dead slot in the middle of it, and its stiffness obviously stiffness than traditional materials such as flitch, strawboards is little, like this, just makes when the hammering stake is pushed up, and it is less relatively that the stake top is subjected to hammering stress, makes the stake top can obtain more effectively protecting.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
A kind of PHC pile tube pile-sinking method waterborne may further comprise the steps:
Piling is prepared.Analyze the geological conditions at pile sinking place, select bearing stratum, PHC pile tube how long is adopted in decision.Analyze structure, size, weight, the length of burying of PHC pile tube.Check the quality of PHC pile tube, mainly check the welding quality of crack, joint,, then will not adopt as defective in quality.Aspect meteorological condition, should be when suitable wave height (with do not influence the steady and anchor hawser of boats and ships pool tighten up be as the criterion) pile sinking, the anxious anxious ebb current that rises is got out of the way in general requirement, and attention wind-force size.The selection of pile sinking equipment, the selection of its king-pile ship should be taken all factors into consideration geological hydrology condition, the long stake of stake type, heavy, the stake ship draft of stake; The selection of plektron should be according to geological conditions and construction experience in the past, in conjunction with the requirement to the pile sinking technical indicator.
Hang stake.The PHC pile tube is long to be L, and the suspension centre design of hanging stake is at distance bottom 0.105L, 0.328L, 0.672L, 0.895L place;
Pitching pile; Aspect the layout of anchor position, correctly arrange anchor hawser position, anchorage according to the operation layout plan that casts anchor of harbour, guarantee that anchor hawser length, the anchor hawser angle under each anchor hawser stress meets the requirements.
Pile sinking, pile sinking are positioned at the incipient stage and are controlled to be main, GPS debugging with transit, orientate the master as with GPS behind the normal pile sinking.Strengthen cooperatively interacting of land personnel and ship's staff, the instant contact guaranteed the precision and the speed of pile sinking.According to Instrument measuring precision and sight line length, locate following departure and carry out plane control, to guarantee the pile sinking precision by permission.Adopt high-strength steel to do to adopt corrugated paper for pile for beating.Simultaneously, when hammer piling, pile monkey, for beating and stake should remain on the same axis replaces to beat to keep voucher, avoids producing eccentric hammering.
Pile sinking is established the caution flag in the pile sinking outermost after finishing immediately, establishes anti-collision alarm red light at night.Carry out steady stake behind the pile sinking, to the good waling of having accomplished fluently of pile holder.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
