Description

Technical Field

[0001] The present application relates to the technical field of pile foundation reinforcement cage deviation detection, and in particular to a detection device for pile foundation reinforcement cage deviation inspection. Background Art

[0002] At present, in the process of pile foundation construction, the accurate placement of steel cage is crucial to the construction quality of pile foundation. With the rapid development of my country's high-speed railway, high-speed railway bridges are lined up one after another. The reinforced concrete engineering in the process of high-speed railway bridge pile foundation construction is the top priority of engineering quality control. One of the key points of pile foundation steel cage control is the deviation of steel cage. The deviation of steel cage directly affects the stability and bearing capacity of pile foundation, and then affects the safety and service life of the entire construction project.

[0003] In the prior art, the methods for detecting the displacement of steel cages mainly include the hanging hammer method, the mechanical arm detection method, and the manual visual method. Among them, the hanging hammer method is to lower the plumb line from the top of the steel cage and determine the displacement by measuring the distance of the plumb line from the center; the mechanical arm detection method uses a mechanical arm with a laser rangefinder sensor to accurately measure the distance between each position of the steel cage and the central target, thereby calculating the displacement value; however, the existing detection methods have some inherent defects. For example, although the hanging hammer method is simple and easy to operate, it is easily affected by external factors such as wind during operation, resulting in inaccurate measurement results; although the mechanical arm detection has the advantage of high precision, its equipment cost is high and requires professional operation. Especially under complex environmental conditions, such as when detecting the displacement of steel cages in a small space, the above methods are difficult to meet the requirements of fast, efficient and high accuracy.

[0004] Therefore, it is necessary to propose a detection device for the inspection and acceptance of the deviation of the pile foundation reinforcement cage to solve one of the above-mentioned technical problems. Summary of the invention

[0005] In order to solve one of the above-mentioned technical problems, the present application provides a detection device for inspecting the deviation of a pile foundation reinforcement cage.
