Construction quality control method for ultra-large volume concrete
The invention discloses a construction quality control method for ultra-large volume concrete, and belongs to the technical field of concrete construction. The construction quality control method forthe ultra-large volume concrete comprises the following steps that a foundation pit is formed in a construction area, a reinforcement cage is arranged on a pit bottom construction platform, and then aforming formwork is constructed;a circulating water pipeline is arranged in the reinforcement cage, and a temperature measuring element is arranged on the reinforcement cage; a concrete pumping pipeline is erected above the reinforcement cage, the concrete pumping pipeline comprises two or more pumping main pipelines, and each pumping main pipeline is connected with two or more pumping branch pipelines arranged at intervals; concrete is pumped to a feeding port of each pumping main pipeline, and concrete valves of the pumping branch pipelines are sequentially and independently opened in the extending direction of the pumping main pipelines, so that the concrete is sequentially poured to a set area;and the poured concrete is maintained. According to the construction quality control methodfor the ultra-large volume concrete, the uniformity of the concrete can be improved, and cracks are reduced.
本申请公开了一种超大体积混凝土施工质量控制方法，属于混凝土施工技术领域。本申请的超大体积混凝土施工质量控制方法包括如下步骤：在施工区域开设基坑，在坑底施工平台上设置钢筋笼，然后构建成型模板；在钢筋笼内布设循环水管道，在钢筋笼上布设测温元件；在钢筋笼上方架设混凝土泵送管道，混凝土泵送管道包括两根以上的泵送主管道，每根泵送主管道上连接有两根以上间隔设置的泵送支管道；将混凝土泵送至泵送主管道的进料口，在沿泵送主管道延伸方向上依次单独打开泵送支管道的混凝土阀门，使混凝土依次浇筑到设定区域；对浇筑后的混凝土进行养护。本申请的超大体积混凝土施工质量控制方法能够提高混凝土的均匀性，减少裂缝的出现。
