Problems solved by technology

[0003] As a high-precision measuring instrument, the foundation pile dynamic tester is easily affected by the environment during transportation and storage, and then the detection accuracy is low, and its measurement object is usually the concrete buried under the soil layer Foundation piles, it is difficult to check the alignment status of concrete foundation piles by direct measurement
In addition, the accuracy of the detection results of the pile dynamic tester will also be affected by the operator's own level of mastery of the pile dynamic tester
[0004] In view of the related technical background mentioned above, the inventor found that in the actual measurement process, the accuracy of the detection results of the foundation pile dynamic measuring instrument is easily affected by environmental factors and the mastery level of the operator, and there is a defect of low accuracy

Embodiment 1

[0047] The following is attached Figure 1-3 The application is described in further detail.

[0048] At present, the foundation pile dynamic tester is usually used in the industry to detect the forming defects of concrete foundation piles by the low-strain reflected wave method. The pile dynamic tester is a kind of precision instrument, which is easily affected by environmental factors and human operation factors during use. Therefore, it is necessary to find a class of standard monitoring samples to calibrate the detection ability of the pile dynamic tester to improve the detection capability of the pile dynamic tester. In order to improve the measurement accuracy of the foundation pile dynamic measuring instrument in the actual use process, the embodiment of the present application proposes a portable simulated defective pile and its usage method.

[0049] The embodiment of the application discloses a portable simulated defect pile. refer to figure 1 and figure 2 , th...

Embodiment 2

[0057] The embodiment of the present application also discloses a portable simulated defect pile. refer to Figure 4 The difference from Example 1 is that the surface of the polytetrafluoroethylene pile 31 is integrally formed with an annular protrusion 312 by injection molding. In the embodiment of the present application, the height of the annular protrusion 312 can be 3 millimeters, and the width can be is 80mm.

[0058] The embodiment of the present application discloses a method for using a portable defective pile, which is used to test the level of personnel's foundation pile dynamic tester mastery, including the following steps:

[0059] Step a: Open the flip cover 12, and then fixedly connect the vibration sensor of the foundation pile dynamic tester to the upper surface of the simulated pile 3;

[0060] In this step, it is necessary to select a calibrated and qualified foundation pile dynamic tester, and make the vibration sensor of the foundation pile dynamic teste...

Abstract

The invention relates to a portable defect simulation pile and a using method thereof, and belongs to the technical field of defect simulation piles and using methods thereof. A portable defect simulation pile comprises a shell, a filling layer arranged in the shell, a simulation pile arranged in the filling layer in a penetrating mode, a base plate arranged in the shell and located at the bottom end of the simulation pile, and a limiting plate arranged in the shell and arranged at the top end of the simulation pile in a sleeving mode. The foundation pile dynamic testing instrument has the effect of improving the accuracy of the detection result of the foundation pile dynamic testing instrument in actual use.

Description

technical field [0001] The present application relates to the technical field of simulated defective piles and its usage method, in particular to a portable simulated defective pile and its usage method. Background technique [0002] The low-strain reflected wave method is one of the main methods for detecting the forming defects of concrete foundation piles. The principle of the low-strain reflected wave method is to collect the vibration wave and reflected wave generated by knocking the foundation pile through the foundation pile dynamic tester, and then infer whether there is a molding defect in the concrete foundation pile according to the waveform. [0003] As a high-precision measuring instrument, the foundation pile dynamic tester is easily affected by the environment during transportation and storage, and then the detection accuracy is low, and its measurement object is usually the concrete buried under the soil layer Foundation piles, it is difficult to detect the ...
