Problems solved by technology
[0003] However, nowadays, when testing the freeze-thaw resistance of concrete test blocks, it is often necessary to manually record the number of freeze-thaw cycles of concrete. Due to the large number of freeze-thaw cycles, manual recording is more cumbersome, and it is easy to miss or record more, making the detection Errors occur in the process. In addition, the traditional freeze-thaw detection device cannot make the concrete test block well affected by the cold and hot air, which affects the effect of freezing and thawing the concrete test block.

The invention belongs to the field of freeze-thaw resistance detection, and in particular relates to a detection device and method for the freeze-thaw resistance of expressway pavement, including a support base, a freeze-thaw cycle box is fixedly connected to the support base, and the freeze-thaw cycle box A plurality of refrigerating plates and electric heating plates are respectively fixedly connected to both sides, and a female rod is rotatably connected to the freeze-thaw cycle box. The present invention can control the power-on and power-off of the refrigerating sheet, the electric heating sheet and the electromagnetic board at intervals through the provided time relay, so that the regulating mechanism can regulate the docking of the counting pen and the counting board according to the freeze-thaw cycle process of the concrete test block, and then Mark on the counting board to automatically record the number of freeze-thaw cycles. Through the cooperation of the set drive motor and the mother rod, the rotation of the concrete test block can be regulated, so that the concrete test block can better accept the effect of cold air or hot air.
Description
technical field [0001] The invention belongs to the field of detection of freeze-thaw resistance, in particular to a device and method for detection of freeze-thaw resistance of expressway pavement. Background technique [0002] Nowadays, in the process of constructing expressways, in order to ensure the quality of highway pavement, it is often necessary to conduct freeze-thaw resistance tests on the concrete on the road surface. Generally, multiple freeze-thaw cycle experiments are carried out on concrete test blocks until the weight loss of concrete If it is greater than 5%, the number of freeze-thaw cycles can be used to judge whether the quality of the concrete meets the required requirements. [0003] However, nowadays, when testing the freeze-thaw resistance of concrete test blocks, it is often necessary to manually record the number of freeze-thaw cycles of concrete. Due to the large number of freeze-thaw cycles, manual recording is more cumbersome, and it is easy to ...
