Mass concrete temperature monitoring method

Abstract

The invention relates to the technical field of bridge temperature monitoring, in particular to a mass concrete temperature monitoring method. The mass concrete temperature monitoring method comprisesthe following steps of: pre-burying a temperature sensor and a cooling water pipe at set positions during concrete pouring; establishing a virtual coordinate system by taking the central point of thebottom surface of the concrete as an original point, determining coordinates of each temperature sensor, and establishing a matrix model according to the coordinates of the temperature sensors; acquiring required temperature information of a horizontal section or a vertical section according to the position information of each coordinate point in the matrix model in combination with the temperature detected by each temperature sensor; and judging whether the temperature information of the required horizontal section or vertical section meets the design requirement or not, if so, conducting noprocessing, and if not, adjusting the water flow speed in the cooling water pipe to meet the design requirement. The mass concrete temperature monitoring method can effectively solve the problems that a temperature monitoring method cannot rapidly and accurately obtain the temperature difference inside and outside mass concrete, sensor grouping is complex and sensor information change and maintenance are complex in the prior art.

Description

technical field [0001] The invention relates to the technical field of bridge temperature monitoring, in particular to a large-volume concrete temperature monitoring method. Background technique [0002] For the large-volume concrete structure cast as a whole, a large amount of heat of hydration will be generated during the hydration and consolidation process of cement; on the other hand, concrete is a poor temperature-conducting material. For large-volume concrete, the internal heat It is not easy to dissipate, and will form a high temperature rise of the heat of hydration, which can reach more than 40°C. During the cooling process, due to non-uniform cooling, it is subject to self-constraints and external constraints. The temperature stress of mass concrete tends to exceed the tensile strength of the corresponding age of concrete, resulting in temperature cracks in the structure. [0003] Therefore, in order to ensure the construction quality of mass concrete structures,...
