Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a slope surface concrete pouring template device. Background Art

[0002] With the development of society, the status of urban underground space projects in construction projects has become increasingly prominent. Improving the quality of underground space structures and ensuring their anti-seepage performance are particularly important. Slope surface concrete is a common structural form of underground space structures, and slope surface concrete pouring is the most common operation in construction projects. At present, when pouring slope surface concrete, most of them reduce the slump of concrete to reduce the fluidity of concrete, and arrange wire mesh in the steel bars to control the flow of concrete. At the same time, during the pouring of concrete, workers continuously shovel the concrete flowing downward to the upper part. With this method, there may be cavities in the concrete below the wire mesh. Moreover, manual work is not only inefficient and requires a large number of people, but also prone to uneven surface of slope surface concrete due to poor concrete vibration quality. Especially for underground structures, it is impossible to achieve the flatness required for waterproofing construction. Or due to the low slump of concrete, the concrete on the slope surface flows during vibration, resulting in insufficient vibration time or incomplete vibration, resulting in vibration leakage, making the concrete density fail to meet the design requirements, and thus causing water leakage and other defects. Utility Model Content

[0003] The purpose of the present utility model is to provide a slope surface concrete pouring formwork device to solve the problem that there may be cavities in the concrete below the wire mesh proposed in the above-mentioned background technology, and that manual operation is not only inefficient and requires a large number of people, but also, due to the poor quality of concrete vibration, it is very easy for the surface of the slope surface concrete to be uneven, especially for underground structures, and the flatness of waterproof construction cannot be achieved or due to the low slump of concrete, the slope surface concrete vibrates and flows, resulting in insufficient vibration time or incomplete vibration, resulting in vibration leakage, so that the concrete density does not meet the design requirements, thereby causing problems such as water leakage.

The slope surface concrete can be fully vibrated, the density of the slope surface concrete is improved, the pouring quality of the slope surface concrete is ensured, and especially the risk of water leakage in underground structures is reduced.
