Dam and diversion box culvert joint concrete construction temperature control method
The invention discloses a temperature control method for concrete construction of a joint part of a dam and a diversion box culvert. The method comprises the following steps: 1, mixing auxiliary materials; 2, cooling the auxiliary material; 3, mixing the concrete; 4, cooling the initial concrete; 5, pouring concrete; and sixthly, concrete gaps are filled. By arranging the protective shed and the heat insulation layer, the situation that the auxiliary material is heated due to direct sunlight can be avoided, and meanwhile heat transfer between the ground and the auxiliary material can be avoided; the spraying head is used for directly spraying water for cooling, calcium chloride powder mixed in the auxiliary materials is combined, after the water is sprayed through the spraying head, the calcium chloride powder is melted when meeting water and absorbs heat in the auxiliary materials, and then the effect of reducing the temperature of the auxiliary materials is achieved. Initial concrete placed in the storage bin is cooled through the water cooling mechanism, meanwhile, dry ice placed in the initial concrete can absorb a large amount of heat during volatilization, then the stirred concrete is cooled, and the concrete can be better cooled through combination of the water cooling mechanism and the dry ice.
本发明公开了一种大坝与导流箱涵结合部混凝土施工温控方法，该方法包括：一、混合辅助料；二、对辅助料进行降温；三、混合混凝土；四、对初始混凝土进行降温；五、浇筑混凝土；六、填充混凝土缝隙。本发明通过设置防护棚和隔热层，可以避免太阳直射导致辅助料升温，同时可以避免地面与辅助料之间传递热量；利用喷淋头直接淋水降温，结合辅助料中混合的氯化钙粉末，经过喷淋头淋水后，氯化钙粉末遇水融化后吸收辅助料中的热量，进而达到降低辅助料的温度的效果；放置在储料仓内的初始混凝土，先通过水冷机构进行降温，同时结合放入初始混凝土内的干冰，在挥发时会吸收大量的热量，进而对搅拌后的混凝土进行降温，两者结合能更好对混凝土进行降温。
