Drawings
FIG. 1 is an overall structural view of the apparatus of the present invention;
FIG. 2 is a diagram showing the overall use of the apparatus of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in figure 1, the acoustic detection device for the integrity of the fixed underwater pile foundation comprises a bearing part 1, a lifting part 2 and a sound wave exploration instrument 3, wherein the bearing part 1 is fixed on a pile foundation 5, the upper end of the lifting part 2 is hinged to the bearing part 1, the sound wave exploration instrument 3 is rigidly connected to the lower end of the lifting part 2, and the sound wave exploration instrument 3 is connected with a terminal.
Bearing part 1 is for falling L type structure, and the perpendicular side of bearing part 1 is fixed with pile foundation 5, generally adopts inflation screw etc. to anchor, plays the primary function of undertaking vertical load, and the upper end of lift portion 2 can be directly articulated with the tip of the horizontal side of bearing part 1, also can be at a fixed hob/connecting rod of the horizontal side tip of bearing part 1, and the upper end of lift portion 2 is articulated with the front end of hob/connecting rod.
The lifting part 2 can have multiple structures, what adopted here is to cut the formula lifing arm, the upper end of cutting the formula lifing arm is provided with control and cuts the handle 4 that the formula lifing arm goes up and down, it is lighter to cut the formula lifing arm quality, be convenient for operation, removal and installation, because its quality is lighter, consequently rock easily when using, the influence detects, consequently set up the pars contractilis 6 in the below of bearing part 1, the both ends of pars contractilis 6 respectively with cut the arm body and the pile foundation 5 articulated of formula lifing arm, what generally adopted is the telescopic link. Of course, if the lifting unit 2 has a structure with a heavy weight and a high stability, the telescopic rod may not be used.
The using method of the device comprises the following specific processes:
1) the bearing part 1 is fixed on the side surface of one direction of the pile foundation 5 to be detected.
That is, the vertical side of the bearing part 1 is fixed to the lateral side of the pile foundation 5 in one direction by an expansion screw or the like.
2) The upper end of the lifting part 2 is hinged with the bearing part 1, and the acoustic wave exploration instrument 3 is arranged at the lower end of the lifting part 2.
If a shear type lifting arm is adopted, the upper end of the shear type lifting arm is hinged with the bearing part 1, the sound wave exploration instrument 3 is arranged at the lower end of the lifting part 2, and two ends of the telescopic part 6 are respectively hinged with the arm body of the shear type lifting arm and the pile foundation 5. If adopt other quality heavier, the strong structure of stability, then with the upper end of portion 2 and the articulated of portion 1 that bears of lift, the setting of sound wave exploration appearance 3 can in the lower extreme of portion 2 that goes up and down.
3) And adjusting the lifting part 2 to enable the sound wave exploration instrument 3 to be at a proper height according to the depth of water at the exploration point of the pile foundation 5.
Namely, the shear type lifting arm is adjusted by the handle 4 according to the depth of water of an exploration point of the pile foundation 5, so that the sound wave exploration instrument 3 is at a proper height.
4) And the sound wave exploration instrument 3 is controlled by the terminal to carry out sound wave scanning, and an underwater image of the pile foundation 5 in one direction is generated.
5) Repeating the process of the step 1-4, and scanning underwater images of the pile foundation 5 in other directions;
because the bearing part 1 is that the anchor needs to punch in advance, and the installation is more troublesome, consequently for the convenience of the underwater image of other positions of the scanning pile foundation 5 in the back, can all fix bearing part 1 around pile foundation 5, during the later stage scanning, only need dismantle the lift portion 2, the pars contractilis 6 and the sound wave exploration appearance 3 of installing more easily can.
