Pouring method of mass concrete
The invention discloses a large-volume concrete pouring method, which relates to the technical field of building construction, and comprises the following steps: firstly, preparing concrete, transferring the concrete into an automobile pump A and an automobile pump B, pouring the bottommost layer of a foundation pit along one direction through the automobile pump A with the pouring thickness of 0.3-0.5 m, and pouring the bottommost layer of the foundation pit along the other direction through the automobile pump B while pouring the automobile pump A with the pouring thickness of 0.3-0.5 m; a vibrating bar is used for vibrating the bottommost layer of concrete poured by the automobile pump A, vibrating points are distributed in a determinant mode, a steel bar with the length of 0.1-0.2 m is inserted into the vibrating points every time vibrating is conducted, and during vibrating, second-layer pouring continues to be conducted on the vibrated bottommost layer of concrete in the pouring direction of the automobile pump A through the automobile pump B; the pouring thickness is 0.3-0.5 m, the upper-layer concrete is covered before the lower-layer concrete is initially set, the steps are repeated until the concrete is poured to the uppermost layer, and reinforcing steel bars do not need to be inserted into the uppermost-layer concrete; the concrete with high pressure resistance can be obtained by using the method for pouring.
本发明公开了一种大体积混凝土的浇筑方法，涉及建筑施工技术领域，包括以下步骤：首先制备混凝土，将混凝土转移至汽车泵A和汽车泵B中，通过汽车泵A对基坑最底层沿着一个方向进行浇筑，浇筑厚度为0.3～0.5m，在汽车泵A浇筑的同时，使用振动棒对汽车泵A已浇筑的最底层混凝土进行振捣，振捣点呈行列式分布，每振捣一次，在振捣点中插入一根长度为0.1‑0.2m的钢筋，在振捣的同时，通过汽车泵B在振捣完成的最底层混凝土上继续沿着汽车泵A的浇筑方向进行第二层浇筑，浇筑厚度为0.3‑0.5m，上层混凝土在下层混凝土初凝之前完成覆盖，重复上述步骤直至浇筑至最上层，最上层混凝土无需插入钢筋；使用该方法浇筑可以得到抗压能力强的混凝土。
