Description

technical field

[0001] The invention belongs to the field of bridge engineering, and in particular relates to an air-blowing and sand-absorbing device for foundation cleaning of bridge foundation steel cofferdam construction. Background technique

[0002] In the construction of underwater bridge piers, steel cofferdams are often used to create a dry working environment. At this time, the bottom of the cofferdam needs to be dredged before the bottom can be sealed. At present, the dredging and sand suction equipment mainly used include sand suction boats and sand suction pumps.

[0003] The sand suction ship is suitable for the environment where the ship can pass. Sand suction pumps are often used in places where the water level is shallow. The ability is not strong and the efficiency is low, the aperture is small, it is easy to get stuck, and the energy consumption is high. Therefore need a kind of strong applicability, strong sand suction force, high efficiency, low cost s...
