Construction method for mass concrete temperature crack control
The invention discloses a construction method for mass concrete temperature crack control, and belongs to the technical field of concrete construction. The construction method comprises aluminum-plastic pipes embedded in concrete, a temperature measuring sensor, copper joints connected with the aluminum-plastic pipes, a flexible conduit on the surface of concrete, an iron wire used for connectingthe aluminum-plastic pipes and the flexible conduit, a U-shaped buckle used for fixing the flexible conduit, a plastic film, felt and a flame-retardant heat preservation quilt, wherein the aluminum-plastic pipes embedded in the concrete are made of any one of a medium-density cross-linked polyethylene material, a high-density cross-linked polyethylene material and medium-density polyethylene; andthe precision of the temperature measuring sensor in the range of 0 to 120 DEG C is 0.5 DEG C, and the temperature measuring sensor detects the temperature. According to the construction method, the creep of the concrete is fully exerted, and the temperature stress is remarkably reduced, so that the anti-cracking safety degree of the mass concrete is greatly improved, the temperature difference between the interior of the concrete and the surface of the concrete is reduced, the possibility of crack generation is reduced, and a heat preservation effect with an obvious effect is achieved.
本发明公开了一种大体积混凝土温度裂缝控制的施工方法，属于混凝土施工技术领域，包括分别埋设在混凝土内部的铝塑管、测温传感器、铝塑管连接的铜接头、混凝土表面的蛇皮管、用于连接铝塑管与蛇皮管的铁丝、用于固定蛇皮管的U型卡扣、塑料膜、毛毡、阻燃保温被，所述埋设在混凝土内部的铝塑管的材质为中密度交联聚乙烯料、高密度交联聚乙烯料、中密度聚乙烯中的任一种，所述测温传感器在0℃～120℃范围内的精度为0.5℃，测温传感器检测温度；本发明混凝土徐变得到充分发挥，温度应力得到显著降低，从而大幅度提高大体积混凝土抗裂安全度，减少混凝土内部与混泥土表面的温度差，降低裂缝产生的可能性，以达到明显效果的保温作用。
