Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pile foundation detection, and in particular to a pile foundation detection device. Background Art
[0002] After the construction of the pile foundation is completed, the pile foundation integrity test should be carried out. According to JGJ106, there are four methods for pile body integrity test, among which the low strain method is a relatively normal pressure method, which saves time and effort and is simple to operate. It mainly generates stress waves by applying an excitation signal to the top of the pile. When the stress wave propagates along the pile body, if it encounters a discontinuous interface, a reflected wave will be generated. Therefore, the propagation time, amplitude and waveform characteristics of the reflected wave can be analyzed by the pile foundation strain detector, and the degree and location of the pile body defects can be determined.
[0003] In the related art, when using the low-strain method to detect the pile body, it is usually necessary to select 2-4 sensor installation points, and the sensor installation points should be at a radius of 2 / 3 from the center of the pile. Therefore, in actual operation, workers need to measure the pile diameter, mark the pile diameter, and then install the sensor. However, there are usually multiple piles of the same specification on the construction site. Repeated measurement of multiple piles will affect the detection speed of the piles and also increase the labor intensity of the workers. Utility Model Content

[0032] A base 3 is provided at the center of the pile, and the base 3 is set in a disc shape. A mounting plate 4 is fixedly connected to the upper end of the base 3, and positioning plates 5 are provided on both sides of the mounting plate 4. The pile body is placed between the two positioning plates 5, and the positioning plates 5 abut against the side walls of the pile body. An adjustment component 6 for adjusting the distance between the two positioning plates 5 is installed on the mounting plate 4.
[0033] The adjustment component 6 includes two adjustment electric telescopic rods 61, which correspond to the positioning plates 5 one by one. The telescopic ends of the adjustment electric telescopic rods 61 are fixedly connected to the positioning plates 5. The axes of the two adjustment electric telescopic rods 61 are located on the same straight line, and the telescopic direction of the adjustment electric telescopic rods 61 is parallel to the diameter of the mounting plate 4. The bottom ends of the adjustment electric telescopic rods 61 are fixedly connected to the arc-shaped side walls of the mounting plate 4.
[0034] Therefore, by controlling the extension and retraction of the electric telescopic rod 61 , the electric telescopic rod 61 can be adjusted to drive the two positioning plates 5 to move toward a side closer to each other or away from each other, thereby changing the distance between the two positioning plates 5 .
[0035] Reference Figure 1 and Figure 2Two calibration electric telescopic rods 7 are provided on the base 3, and the telescopic direction of the calibration electric telescopic rods 7 is parallel to the upper end surface of the mounting plate 4. The bottom end of the calibration electric telescopic rod 7 is rotatably connected to the upper end surface of the mounting plate 4, and the calibration electric telescopic rod 7 can rotate around the axis of the mounting plate 4. The telescopic end of the calibration electric telescopic rod 7 is provided with a calibration pen 8 and a fixing mechanism 9 for fixing the calibration pen 8 to the end of the calibration electric telescopic rod 7.

The fixing mechanism 9 includes a fixing ring 91, a locking bolt 93 is threadedly connected to the arc surface of the fixing ring 91, a rubber block 931 is fixed to the rod of the locking bolt 93, and the locking bolt 93 presses the calibration pen 8 in the fixing ring 91 through the rubber block 931. A connecting component 92 for connecting the fixing ring 91 and the end of the calibration electric telescopic rod 7 is provided between the fixing ring 91 and the end of the calibration electric telescopic rod 7.
[0037] Reference Figure 1 and Figure 2 The connection assembly 92 includes a connection block 921, which is fixedly connected to the end of the calibration electric telescopic rod 7.
