Background
In actual engineering construction, the mass of concrete has a significant influence on the whole engineering quality, the hardened concrete has sufficient strength and durability indexes to bear load and resist corrosion of environments, the important index is the compactness of the concrete, the compactness of the concrete is the proportion of the volume of solid substances of the concrete to the total volume, the concrete is filled by the solid substances in the concrete volume, namely the compactness of the concrete is reflected, and the higher the compactness, the higher the density, the better the overall performance of the material.
At present, three common methods for detecting the compactness of the concrete filled steel tubular column are generally adopted:
the core drilling method is characterized in that holes are drilled in a formed concrete-filled steel tube column for core pulling, the quality of concrete in the column core is judged according to the quality condition of a drilled core sample, obviously, the core drilling method can only continuously detect the quality of the concrete at a certain test point, cannot comprehensively judge the quality condition of the whole concrete column, and has large limitation; moreover, the grouting reinforcement of the drilled hole is difficult to meet the strength equal to the whole column core concrete, so that the risk of damaging the integrity of the concrete column exists, and the stress of the concrete column can be weakened in serious cases; in addition, the core drilling method has the defects of long period, high cost, difficult erection of core drilling equipment on the steel pipe concrete column and the like.
The second, ultrasonic method, its basic principle is to utilize the transmitting transducer to radiate the high-frequency vibration at one end of the steel pipe external diameter, transmit to the receiving transducer of the other end of the steel pipe external diameter through the centre of a circle of the steel pipe, the ultrasonic wave will change propagation direction and route when meeting the interface formed by various defects in the course of spreading, its energy will be attenuated in the defect place, cause the ultrasonic wave to reach the relative change of sound time, sound amplitude, frequency when receiving the transducer. The method is high in cost and seriously influenced by construction environment, so that the method is high in theoretical performance but low in feasibility in the actual construction process.
The knocking method is suitable for generally inspecting the quality of the column core concrete, completely depends on the technology and experience of technicians, and is greatly influenced by subjective factors; moreover, the knocking method lacks theoretical basis and data for archiving, and is inconvenient for construction technology management and quality detection technology management; in addition, the tapping method is difficult to accurately judge for a concrete filled steel tubular column with a large wall thickness.
