Abstract

The invention relates to a concrete cooling water pipe device, and belongs to the technical field of concrete casting construction. Aiming at the problems of slow cooling of a core temperature area and incapability of distinguishing and controlling the flow in a traditional method due to arrangement of a cooling water pipe in a thin-wall concrete structure in a snakelike form for water introduction, the cooling water pipe is transversely arranged in parallel; cooling water is firstly fed from the center position of a concrete body in parallel; and through the flow adjustment of water pipes with different elevations, the introduction quantity of the cooling water at different parts is finely controlled, so that the problems caused by snakelike arrangement of the traditional cooling water pipe can be effectively solved, the reversing cost of the cooling water is saved, and meanwhile, part of equipment can be recycled. The device can effectively improve the thin-wall concrete quality andreduce the temperature crack occurrence probability.

Description

technical field [0001] The invention relates to a concrete cooling water pipe device, which belongs to the technical field of concrete pouring construction. Background technique [0002] In the field of hydropower engineering, the method of pre-embedded cooling water pipes is widely used in the temperature control process of concrete pouring. However, in thin-walled concrete structures such as cavern linings, the traditional method of burying circular pipes and passing water for cooling often brings practical engineering problems. When the water flow of serpentine water pipes reaches the center of the concrete body, the temperature of the cooling water is already high , at this time the control effect on the high temperature of the concrete core is limited. The result of this is that it is difficult for the concrete core temperature to drop to the expected temperature, and the temperature gradient in the direction of the narrow side is large, which is prone to cracks, affec...
