Research on Temperature Control of Mass Concrete - - Application of Embedded Cold Water Pipe Technology

In order to solve the problem of heat release during the construction of concrete dams, the embedded cold water pipes are used to control the temperature. The finite element method is used to discuss the relationship between the cooling effect, cost and project safety when the pipes have different arrangement forms, diameter, material, spacing and water flow temperature. The results show that when the pipes are arranged in rectangular shape, the pipe diameter is 0.016m and the spacing is
$\mathbf{1}.\mathbf{5}\mathbf{m}\times \mathbf{1}.\mathbf{5}\mathbf{m}$
, the comprehensive effect is the best. Piping material has little effect on reducing concrete temperature; When the water flow temperature is too low, it is easy to cause the internal cracking of concrete, which should be paid attention to in the construction.
