Description
Technical Field
The invention belongs to the field of foundation pile detection, relates to a foundation pile detection technology, and particularly relates to a building foundation pile detection device and a detection method thereof.
Background
The main methods for detecting the pile foundation include a static load test, a core drilling method, a low strain method, a high strain method, a sound wave transmission method and the like. The static load test is the most direct and reliable test method for detecting the vertical compression bearing capacity of the foundation pile. However, in engineering practice, the problem of the reference pile is sometimes overlooked by a detection person, so that the driving depth of the reference pile is insufficient, and the displacement is easily generated in the test process.
For detecting the pile foundation by a high strain method, the main function of the method is to judge whether the vertical compression-resistant bearing capacity of the pile meets the design requirement. When the high-strain method is used for judging defects such as horizontal integrated gaps of a pile body, joints of a precast pile and the like, the defect degree can be reasonably judged on the basis of finding out whether the defects influence the vertical compression-resistant bearing capacity, and the high-strain method can be used as a supplementary verification means of the low-strain method. In some areas, it has become common practice to increase the frequency of spot checks for load bearing capacity and integrity by high strain methods.
However, the conventional high-strain method for detecting the pile foundation generally adopts a mode of generating vibration force in a free falling body of a heavy hammer, but the mode has the following problems: firstly, the traditional high strain method detects the mode that the weight in the pile foundation adopts manual unhook, when the unhook is not thorough, has great potential safety hazard. Secondly, when the traditional heavy hammer moves in a free falling body, the traditional heavy hammer is difficult to protect the accurate hitting detection center position, and the deviation exists, so that the data is inaccurate. Moreover, in the prior art, when the heavy hammer is in a free naked body, the impact force of the heavy hammer is not accurately controlled, the pile foundation cannot be subjected to effective pressure impact in a mode desired by a worker, and the pile foundation cannot be accurately evaluated under the condition of various accurate data, and can only be roughly known by experience;
in order to solve the above-mentioned drawbacks, a solution is now provided.
