Description

Technical Field

[0001] The invention belongs to the technical field of pipe pile detection, and in particular relates to a device for detecting the inner surface integrity of a prestressed pipe pile. Background Art

[0002] Prestressed pipe piles are a type of precast concrete piles with the characteristics of high single pile bearing capacity, low unit bearing capacity cost, fast construction speed, and reliable pile quality. Generally, they are suitable for soft soil, clay, silt, sandy soil, and fully weathered rock mass. They are widely used in construction, railways, highways, bridges, ports, docks and other projects. Pipe piles can effectively share the load of the superstructure and transfer it to the base layer to improve the overall stability. They are deeply buried in the soil and enhance the structure's anti-overturning and anti-slip capabilities. They are particularly outstanding under poor soil or water conditions. At the same time, they can reduce the settlement of buildings and maintain the horizontality and stability of the structure. They are suitable for a variety of geological conditions, including soft soil, fill, etc., especially for providing support on foundations with insufficient bearing capacity. Moreover, since they are produced in the factory in advance, they only need to be driven into the soil during on-site construction, shortening the construction period, reducing on-site concrete pouring, and reducing noise and dust pollution.

[0003] The inspection of prestressed pipe piles usually includes multiple tests. When inspecting the integrity of the inner surface of the pipe piles, the inspection methods mainly include ultrasonic inspection, X-ray imaging, magnetic particle inspection and eddy current inspection. Existing inspection devices have detection errors or inaccuracies during use, which in turn affect the inspection results. Summary of the invention

[0008] Furthermore, the movable support mechanism includes a triangular support limit shell installed inside the first support shell or the second support shell, and a plurality of sliding square tubes are slidably connected to the triangular support limit shell, and a vortex block is fixedly connected to one side of the bottom of the plurality of sliding square tubes, and a convergence spring is installed inside the plurality of sliding square tubes, and the other ends of the plurality of convergence springs are fixedly connected to a sliding shaft column, and rollers are installed on the plurality of sliding shaft columns.

[0009] Through the above technical solution, a hexagonal wrench is inserted into the square hexagonal slot block for rotation, thereby driving the two driving gear plates to rotate, and through engagement with multiple vortex tooth blocks, driving multiple sliding square tubes to extend outward at the same time under the limit of two triangular support limit shells until multiple rollers contact the inner wall of the prestressed pipe pile body.

During the jetting process, the air pump inputs the gas into the air inlet housing 801 through the extension pipe 812 and the connecting hard pipe 810, guides the gas to the inside of the rotary connector 803 through the first guide cone 802, and then disperses the airflow to the multiple output air pipes 806 around through the second guide cone 804, so as to realize continuous jetting, and clean the internal dust of the prestressed pipe pile body 1 by jetting;

[0052] After the overall processing and transmitting equipment is moved to the other end of the prestressed pipe pile body 1, the ultrasonic receiving mechanism 13 is installed, and the two bidirectional threaded rods 1305 are rotated to drive the multiple threaded support blocks 1306 to expand outward under the limit of the cross support frame 1302, until the multiple threaded support blocks 1306 are attached to the inner wall of the prestressed pipe pile body 1, thereby completing the fixation of the overall ultrasonic receiving mechanism 13 and making the ultrasonic receiver 1303 in the center position. Finally, the controller 1003 controls the multiple ultrasonic transmitters 1002 to emit sound waves. The sound waves emitted by the multiple ultrasonic transmitters 1002 are continuously reflected on the inner wall of the prestressed pipe pile body 1, and are finally received by the ultrasonic receiver 1303. The integrity of the inner wall of the prestressed pipe pile body 1 can be determined by analyzing the received sound wave signals by a computer.
