[0002] Slope independent foundation is a common foundation form, mainly used for bearing and dispersing the load of building or structure. In order to save concrete, the top surface of the foundation is usually designed to be a slope according to design calculation, which brings certain difficulty in the process of concrete pouring due to the unique structure of the slope. After concrete pouring, the visual quality is poor, the slope ratio is inconsistent, and the concrete pouring time is long, etc. In order to solve the above problems, one method is to install a formwork on the top surface of the foundation, which also increases the formwork engineering quantity, and the upper reinforcement is difficult, and the cost reduction is very small through cost analysis and comparison, and it is rarely used in engineering entities. Through a series of research investigations, because the slope concrete itself is flowing, the concrete flows downward, a more common method is to reduce the slump of the concrete, and the upper slope concrete is poured in layers before the initial setting of the bottom concrete, due to the slump of the concrete itself, and the extension of the pouring time, it is easy to appear cold joint if it is not controlled well, which has a fatal impact on the quality of the independent foundation concrete. In order to avoid the appearance of cold joint, the pouring speed should be appropriately accelerated during construction, more manpower is needed for the pouring of slope concrete, and a long time is spent on leveling and lightening treatment of slope concrete.
