Cofferdam launching method
The invention discloses a cofferdam launching method, and relates to the field of cofferdam construction. The method includes the following steps that A, a launching site is distributed, an air bag and an anchor are distributed on the launching site, a floating box is arranged on the air bag and comprises multiple sections, the interior of each section is provided with a water pipe, a cofferdam is spliced on the floating box, the cofferdam is connected with the anchor through a hawser, and the air bag is inflated after the cofferdam is spliced; B, the hawser is cut off, the cofferdam and the floating box are launched, water is injected into the water pipes until the floating box is separated from the cofferdam and sinks into the water bottom, water injection stops, the position of the cofferdam is changed, and water in each section of the floating box is extracted through the corresponding water pipe until the floating box automatically emerges from the water. When the cofferdam is launched, buoyancy force is provided for the cofferdam through the floating box so that the launching depth can be effectively reduced, and the water depth requirement of a water inlet is reduced; after the cofferdam is launched, the floating box can be separated from the cofferdam by injecting water into the floating box, the water in the floating box is pumped out, the floating box does not need to be salvaged and can automatically emerge from the water, and recycling is convenient.
