Description

Technical Field

[0001] The invention relates to the technical field of underwater concrete construction, and in particular to an underwater concrete spraying and pouring device and method. Background Art

[0002] Underwater concrete pouring technology is a key technology for repairing underwater buildings and restoration projects such as dams, bridge foundations, docks and other marine or river structures. Traditional underwater pouring methods face many challenges, including the direct contact between concrete and water, which may lead to cement slurry loss, reduced strength and durability, and uneven concrete quality. For damage to the bottom plane of hydraulic structures, the conduit method, hanging tank method, bag method and other technologies can be used for repair. These methods can directly deliver concrete to the bottom, reducing the risk of pouring leakage and water segregation of concrete.

Due to the uneven foundation surface of the facade, the formwork is difficult to install in a sealed manner, which may cause concrete to leak from the gaps and be washed away by water during the pouring process, which can easily affect the quality of the concrete.
