Description

Technical Field

[0001] The present invention relates to the technical field of water intake head prefabrication, and in particular to a water intake head prefabrication device and a prefabrication method. Background Art

[0002] During the pouring of water head concrete, to improve the structural density and impermeability of the water head, the cement is usually vibrated and compacted to eliminate air gaps in the cement. Currently, the most common method is insert vibrating, where an electric or pneumatic vibrator is inserted vertically into the concrete layer to perform layer-by-layer vibration.

[0003] However, excessive vibration can easily cause aggregate sinking and cement slurry floating, resulting in a gradient distribution of concrete strength. This is particularly true in large-volume water head structures, where strength loss at the layered interfaces is high. Furthermore, during layered pouring, the upper vibrator needs to be inserted 5-10 cm into the lower, initially set concrete to ensure interlayer bonding. However, improper control of the insertion depth can damage the underlying setting structure. Furthermore, after pouring each layer, the concrete needs to be paused until it reaches the initial setting state, which prolongs the pouring cycle for large-volume water heads. Cold joints caused by improper control of the interlayer pouring intervals are particularly prominent in splash zone water heads.

[0004] In view of the above-mentioned related contents, there is an urgent need for a water intake head prefabrication device and prefabrication method to improve the problem of difficult vibration during the water intake head prefabrication process. Summary of the Invention
