Embodiment Construction

[0037] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0038] see figure 1 , the foundation pile three-dimensional detection device based on borehole radar according to the present invention is based on the foundation pile 10 with a through hole 12 inside, and the through hole 12 extends along the axial direction of the foundation pile 10, and the detection device includes:

[0039] The borehole radar includes a well antenna 40 and a radar host 60 electrically connected to each other. The well antenna 40 is arranged in the through hole 12 for three-dimensional scanning detection of the space where it is located. The radar host 60 is used to receive the well antenna 40. Probe data sent.

[0040] The antenna 40 in the well includes a positioning unit 41, a directional antenna 42, a counterweight 43 and a connecting cable that are sequentially connected from top to bottom. Micromotor 411 and several position sens...

Abstract

The invention relates to a three-dimensional foundation pile detection device and method based on a borehole radar. On the basis that a foundation pile is internally provided with a through hole, and the through hole extends in the axial direction of the foundation pile, the three-dimensional foundation pile detection device based on the borehole radar comprises the borehole radar, a traction module and a central control module. The borehole radar comprises an in-well antenna and a radar body, wherein the in-well antenna is connected with the radar body, and the radar body is connected with the central control module. The three-dimensional foundation pile detection method comprises the steps of positioning the in-well antenna, conducting three-dimensional scanning detection, conducting shifting detection, transmitting data, generating a three-dimensional image and the like. By the adoption of the technical scheme, detection of the integrality of the foundation pile, the thickness of pile bottom sediments and the length of a steel reinforcement cage can be achieved, the three-dimensional image can be obtained, and a detector can visually see the conditions of the foundation pile and the surroundings of the foundation pile.

Description

technical field [0001] The invention relates to the field of integrity detection of foundation piles, and more specifically, to a three-dimensional detection device for foundation piles based on drilling radar and a three-dimensional detection method for foundation piles based on the device. Background technique [0002] Among the conventional detection methods for the integrity detection of building foundation piles, the acoustic wave transmission method, the high-strain and low-strain method, and the core-drilling method are more common. Quite a few questions. Among them, the acoustic wave transmission method, low strain method and high strain method are non-destructive testing methods, but there are large test blind spots. They can be attributed to two-dimensional detection technology methods, which can only judge the depth position of the abnormality but cannot judge its orientation. Due to the limitations of the method itself, it is impossible to judge whether the abno...
