Description

Technical Field

[0001] The invention belongs to the technical field of highway construction, and in particular relates to a concrete detection device and a detection method for highway construction. Background Art

[0002] In the process of highway construction, cement concrete is the most important foundation material in road construction. The strength of cement concrete has a great influence on the quality of the project. Among them, the compressive strength of concrete is an important indicator for evaluating the quality of the road. Therefore, it is an important task to do a good job in the strength test of cement concrete in road construction. Concrete strength is one of the important indicators of mechanical performance standards. The higher the strength of concrete, the stronger its rigidity and the stronger its ability to resist erosion. However, if the strength of cement concrete is too high, it will be fragile and easy to crack, which will also affect the quality of the road project. In the construction of highway projects, the strength parameters of cement concrete can effectively reflect the changes in the state of construction materials, the construction process and construction standards adopted in the construction process, and the flatness of the road after construction. These are all matters that need to be paid attention to in the highway quality inspection and evaluation.

[0003] Among them, the core drilling sampling method is a commonly used method for testing the strength of cement concrete during highway construction. This method uses a special drilling rig and a man-made diamond hollow thin-walled drill bit to drill core samples on an already formed concrete structure to detect concrete strength and defects. It is mainly used to detect the strength of concrete, the quality of concrete joints and stratifications, the depth of concrete cracks, segregation, holes and other defects. The core drilling method is intuitive, accurate and reliable, and is an effective method that cannot be replaced by other non-destructive testing methods.

[0004] The traditional concrete testing device for highway construction based on core sampling has some shortcomings when in use. First, it is easy to cause damage to the peripheral area during the core sampling process, which increases the difficulty of repair; second, it cannot collect and process the dust generated during the core sampling process, which affects the environment and traffic safety. Therefore, it needs to be optimized and improved. Summary of the invention
