Description
Technical Field
The utility model relates to the technical field of concrete pouring construction, in particular to an intelligent temperature measurement system of an ultra-thick cast-in-place concrete structure.
Background
Mass concrete refers to a substantial amount of concrete having a concrete structure entity minimum geometrical dimension of not less than 1m, or concrete expected to cause harmful cracks due to temperature change and shrinkage caused by hydration of a cementitious material in the concrete, as defined in GB50496-2009 'mass concrete construction specifications'. During construction, concrete generates a lot of heat due to cement hydration reactions. Because concrete is a poor conductor of heat, the heat inside the mass of concrete is difficult to dissipate, the outer surface is greatly influenced by the ambient temperature, so that the temperature difference between the inside and the outside is generated, and when the temperature difference between the inside and the outside is large to a certain extent, cracks are generated on the surface of the concrete. Therefore, the temperature difference, the cooling rate and the environmental temperature of the inner surface of the mass concrete pouring body are tested according to the standard requirements in the mass concrete pouring construction stage, and temperature control measures are adopted for the concrete according to the real-time temperature condition, so that quality accidents such as cracks and the like of the concrete are avoided.
And determining a temperature measuring position and a temperature measuring point according to factors such as the length, the width, the thickness, the shape and the like of the large-volume concrete pouring body. And each temperature measuring station is at least provided with a surface layer, a bottom layer and a central temperature measuring point along the thickness direction of the concrete pouring body. The temperature sensor should be fixed firmly and should be kept apart with structure reinforcing bar and mount metal body. At present, the temperature sensor is directly embedded in concrete and is put into a metal pipe. In contrast, the concrete is directly embedded, and the test value is more accurate and more convenient. However, in the existing direct embedding method, the position of the temperature measuring point is inconvenient to adjust, the field adjustable space is small, the universality is poor, a reliable fixing method is lacked, and the problem that the temperature sensor and the structural steel bar are touched due to concrete vibration so as to influence the temperature measuring precision is very easy to occur.
