Description
Technical Field
The invention relates to a coring device for concrete detection.
Background
The concrete core sample is directly drilled on the structural concrete, and the compressive strength test is carried out after the core sample is processed, so that the method is known as a test method for detecting the concrete strength more intuitively and reliably. The core-taking method and the technical operation refer to the technical specification of concrete strength detection by a core-drilling method promulgated in China, and the technical requirements of core-drilling samples are as follows: 1. the drill core is suitable for structures or components with concrete strength grade larger than C10. 2. The rigid position is detected in advance before drilling, and the drilled core sample does not contain reinforcing steel bars, particularly longitudinal reinforcing steel bars parallel to the axis of the core sample, so that the compressive strength of the core sample is not influenced. If the component with dense reinforcing bars cannot avoid opening, two reinforcing bars with the diameter less than 10mm are allowed to be contained in the core sample at most. 3. The number of core samples in the detection of a single component is not less than 3. 4. The diameter of the drilled core sample should generally not be less than 3 times the maximum particle size of the aggregate, in any case not less than 2 times. The standard core sample is the core sample with the diameter of 100mm or 150mm and the ratio of height to diameter of 1-2 specified in the national regulations (CECS 03: 88). For core samples with a height to diameter ratio h/d >1, the correction of the intensity by the correction factor alpha is taken into account. 5. The end face of the core sample is ground flat to prevent the influence of stress concentration caused by unevenness on the actually measured strength. 6. Holes left on the structure after drilling and coring are repaired by adopting micro-expansive concrete with the original concrete strength higher by one level in time. The traditional coring equipment at present adopts a high-power electric drill to drive a hollow drill bit to directly drill, the drilling mode is easy to deviate, and the drilling depth is not easy to control.
