Abstract

PURPOSE:To exchange gates without the needs to lower the level of water by a method in which a preliminary gate is set on the downstream side of an existing gate, the existing gate is pulled out to the upstream side in a state of being floated, and a new gate is carried in an installation site. CONSTITUTION:In exchanging gates, the first preliminary gate 12 is set on the upstream side of an existing gate 4, the water pressures between the upstream and downstrea sides of the gate 4 are balanced, and the gate 4 is removed from a gate groove 5 and pulled out to the upstream side in a state of being floated. The second preliminary gate 14 is then set on the upstream side of the gate installation site, and water on the downstream side of the gate 14 is drained by opening the gate 12 to improve the door catch in dry state. Afterwards, water is temporarily stopped by the gate 12, the gate 14 is removed out, and a new gate in a state of being floated is carried in a gate installation site. The first preliminary gate 12 is then removed out.

Means for Solving the Problems In order to solve the above problems, the present invention temporarily closes the downstream side of the existing gate with a closed structure in a water gate with a first preliminary gate, balances the water pressure upstream and downstream, and closes the existing gate. The gate is floated, the existing gate that has been floated is pulled out to the upstream side and removed, a second spare gate is installed upstream of the gate installation position and temporarily closed, and the first spare gate is opened. Drain the water downstream from the second preliminary gate and modify the door stop, then temporarily seal it with the first preliminary gate again, remove the second preliminary gate, float the new gate, and place it in the gate installation position. Next, the second preliminary gate is installed again and temporarily closed, and the area downstream of the second preliminary gate is flooded with water (by opening the first preliminary gate), and the new gate is installed. It is installed in a certain position.
