The invention relates to a manufacturing method of a concrete test piece containing sensors and the concrete test piece. The method comprises the steps of calculating the number and positions of required sensors according to measurement requirements in the concrete test piece; setting the size of a concrete prism, making the height of the concrete prism to be the same as the pouring depth of the concrete test piece, and enabling the area of the cross section, perpendicular to the height, of the concrete prism to cover any projection area of one sensor; designing the height position of the sensors on the concrete prism according to the required depth position of the sensors; pouring a template of the concrete prism embedded with the sensors to form the concrete prism; vertically arranging the concrete prism in a template of the concrete test piece according to the horizontal position of the required sensors; and pouring the template of the concrete test piece to form the concrete test piece containing the sensors. The problems that in the prior art, the position of sensors in the concrete test piece cannot be accurately arranged, and data measurement is inaccurate are solved.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for manufacturing a sensor-containing concrete test piece and the concrete test piece. Background technique [0002] In the research and design of reinforced concrete structures, the internal temperature distribution of concrete structures at high temperatures is an important parameter. Embedding temperature sensors such as thermocouples at different depths inside the concrete is the main means to obtain the law of temperature changes inside the concrete structure. [0003] However, in the production of concrete specimens, due to the fluidity of the concrete after pouring, it is difficult to achieve accurate arrangement and positioning of sensors. Some researchers pre-embed steel bars in the test, and then fix the temperature sensor on the steel bar by binding. Although this method can fix the temperature sensor, the thermal conductivity of the steel bar and c...
