Description
Technical field
This utility model relates to seamless binding in pile body side for the technical field of Low Strain Dynamic Testing of Piles, is particularly suited for
The technical field of PHC pile tube integrity low strain integrity testing under port engineering existing structure.
Background technology
Stake harbour, as one of big structural shape of harbour three, is built more at China's riverine and coastal, but these harbours is big
Part is all built in last century 80, the nineties, during long-term use, due to by various factors (such as harbour overload, surprisingly
Shock, the burn into material corrosion deterioration etc. of sea water) impact, service behaviour reduce, even lose normal ability to work,
Foundation pile is as the primary structure member of support long piled wharf superstructure, and the safety to long piled wharf is most important.Deform at bank slope
With under displacement, ship collision and other natural environment and working load effect, foundation pile is easy to fracture equivalent damage phenomenon occur, by
In foundation pile subregion below the water surface and mud face, its damage status cannot determine.The analysis of foundation pile technology status need to be by right
Pile body carries out integrity detection, it determines the degradation of pile body, provides concrete classification.
But, under carrying out existing structure during PHC pile tube integrity detection, due to Site Detection complicated condition:
(1) long the unknown of actual stake, concrete velocity of wave is difficult to determine；(2) for the stake under existing structure or the stake of uneven pile body, should
Reeb is at structure interface face or stake top is the most descending but also up, and traditional overhead sensor test instrument and method test are by mistake
Difference maybe can not predict a defect relatively greatly.
Therefore, this for PHC tubular pile body integrity detection under current existing maritime structrue without free exciting face, defect
The technical barrier that position cannot accurately judge, works out a kind of auxiliary knocking device can being seamless bonding with PHC pile tube.Can be quick
Accurately judge PHC tubular pile body integrity, while improving operating accuracy, also substantially increase work efficiency.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of existing maritime structrue
Lower PHC pile tube integrity low strain integrity testing auxiliary knocking device.
For solving above-mentioned technical problem, under this utility model a kind of existing maritime structrue of offer, PHC pile tube integrity is low should
Becoming detection auxiliary knocking device, including exciting block, it is characterized in that described exciting block is cuboid, wherein one side is sunk arc
Face, matches with PHC pile tube, and length L of this knocking device is relevant with cambered surface central angle A and stake footpath R: L=。
Further, the radius of described cambered surface is consistent with the radius of the PHC pile tube of required detection.
Further, the scope of the width B of described exciting block and height H is 30-50mm.
Further, this exciting block described is the model according to PHC pile tube, uses identical with PHC tubular pile concrete label
Concrete prefabricated form.
Further, described exciting block passes through binding agent together with PHC pile tube close-coupled.
Further, pile's integrity testing instrument and two biographies matched with described pile's integrity testing instrument are also included
Sensor, wherein sensor is successively set on the PHC pile tube below this knocking device.
Further, described exciting block is away from stake apex distance from for 50～100cm, and first sensor is more than away from exciting block distance
In 50cm, transducer spacing is 50～100cm, specifically should be depending on on-site actual situations.
The beneficial effect that the present invention is reached: 1) avoid Cutting platform on PHC pile tube, it is achieved the mesh of Non-Destructive Testing
's；2) ensure preferably to transmit energy and waveform between same media with the concrete test block of label；3) this detection method exciting
Force direction is parallel with stake axis direction, can avoid the oscillation crosswise impact added；4) auxiliary knocking device realizes nothing with PHC pile tube
Seam bonding, and simple to operation, can quickly, accurately identify pile integrity.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in Fig. 1-1,1-2,1-3 and Fig. 2, under a kind of existing maritime structrue, PHC pile tube integrity low strain integrity testing is auxiliary
Helping knocking device, including exciting block, it is characterized in that described exciting block is cuboid, wherein one side is sunk cambered surface, with PHC
Pile tube matches, and length L of this knocking device is relevant with cambered surface central angle A and stake footpath R: L=；
The radius of described cambered surface is consistent with the radius of the PHC pile tube of required detection；
The scope of the width B of described exciting block and height H is 30-50mm；
This exciting block described is the model according to PHC pile tube, uses the concrete identical with PHC tubular pile concrete label pre-
