Concrete temperature adjusting system for overwintering long intermittent surface of dam in severe cold area and operation method
The invention discloses a severe cold area dam overwintering long intermittent surface concrete temperature adjusting system and an operation method, the severe cold area dam overwintering long intermittent surface concrete temperature adjusting system comprises an old concrete temperature adjusting pipe network arranged in lower-layer old concrete, and the lower-layer old concrete is located below a dam overwintering long intermittent surface; a new concrete temperature adjusting pipe network is arranged in the upper-layer new concrete above the dam overwintering long intermittent surface, the old concrete temperature adjusting pipe network is used for heating and cooling the lower-layer old concrete, and the new concrete temperature adjusting pipe network is used for heating and cooling the upper-layer new concrete; the temperature gradient and temperature stress of the interior and surface layer of old concrete of the overwintering long intermittent surface of the dam, the temperature gradient and temperature stress between new and old concrete and the temperature gradient and temperature stress of the interior and surface layer of new concrete are reduced, the temperatures of special periods, special parts and weak links of dam concrete pouring are effectively controlled, and the cracking phenomenon is prevented; and powerful guarantee is provided for safe operation of the dam.
本发明公开一种严寒地区大坝越冬长间歇面混凝土调温系统及运行方法，包括设于下层老混凝土内的老混凝土调温管网，所述下层老混凝土位于大坝越冬长间歇面下方，所述大坝越冬长间歇面上方的上层新混凝土内设置新混凝土调温管网，所述老混凝土调温管网用于对下层老混凝土进行升温和降温过程，所述新混凝土调温管网用于对上层新混凝土进行升温和降温过程；本发明减少了大坝越冬长间歇面老混凝土内部和表层、新老混凝土之间、新混凝土内部和表层的温度梯度和温度应力，对大坝混凝土浇筑特殊时段、特殊部位和薄弱环节的温度进行有效控制，防止开裂现象的产生，为大坝安全运行提供有力保障。
