Problems solved by technology

[0004] However, the existing detection of the integrity of the pile foundation is carried out manually, which has a large workload and low intelligence. Due to the large errors in the operation of the personnel, the measurement accuracy is not high. Therefore, we propose a pile foundation integrity detection method Small strain detection robot

Abstract

The invention relates to the technical field of pile foundation detection equipment, in particular to a small-strain detection robot for detecting the integrity of a pile foundation. The robot comprises a detection arm, walking mechanisms are arranged at the two ends of the detection arm, and the walking mechanisms at the two sides are connected into an integral structure through a handle of a U-shaped structure; a slide rail is fixedly arranged at the bottom of the detection arm in the length direction of the detection arm, a first slide block and a second slide block are connected to the slide rail, and slide driving mechanisms are arranged on the first slide block and the second slide block; a detection mechanism is fixedly arranged at the bottom of the first slide block, a grinding mechanism is arranged at the bottom of the second slide block, and a knocking mechanism is arranged in the middle of the top of the detection arm; a control box is further fixedly arranged on the walkingmechanism at one side, and a control unit is arranged in the control box. According to the small-strain detection robot intelligent detection for the integrity of the pile foundation is achieved, the labor intensity is effectively reduced, the working efficiency is improved, and the detection precision is also improved.

Description

technical field [0001] The invention relates to the technical field of pile foundation detection equipment, in particular to a small strain detection robot for pile foundation integrity detection. Background technique [0002] In building construction, low-strain dynamic detection is commonly used in the integrity detection of pile foundations. The basic principle is: a stress wave is generated by applying an excitation signal on the top of the pile. When the stress wave propagates along the pile body, it encounters a discontinuous interface (such as Honeycomb, mud, fracture, hole and other defects) and the bottom surface of the pile will generate reflected waves, and the integrity of the pile can be judged by detecting and analyzing the propagation time, amplitude and waveform characteristics of the reflected waves. [0003] The theoretical basis of small strain is the one-dimensional stress wave theory. The basic principle is to impact the pile top with a small hammer, and...
