Abstract

[0002] Concrete is the main building material in the construction of basements, hydropower plant dams, and river flood control dams. There are many large-volume concrete parts involved and the structure size is large. After the concrete is poured, the heat dissipated quickly on the concrete surface and the internal cement hydration heat release is concentrated, resulting in a rapid temperature rise, causing the temperature difference between the inside and outside of the concrete to be greater than 25°C. The thermal expansion and contraction phenomenon causes temperature cracks in the concrete, which seriously affects the structural strength, structural safety and normal use. Therefore, during the pouring process of concrete, the temperature of the concrete needs to be monitored by a temperature measuring device. The existing temperature measurement method is mostly to fix the temperature sensor head on the steel mesh, which is covered by the concrete when pouring the concrete. This makes the temperature sensor head unable to be used again, which not only wastes resources, but also increases the cost of construction. For this reason, we propose a temperature measuring device for large-volume concrete raft construction. Utility Model Content
