After the temporary gate device is installed, water begins to be pumped in the working well, and the depth of sewage in the working well is controlled to be 4-5 m. Meanwhile, the water level behind the gate is gradually reduced until the gate is drained, and in the process, the water level behind the gate is continuously reduced along with the continuous rising of the water level of the working well, and the water pressure acting on the gate is gradually increased. Under the action of water pressure, the edge of the temporary gate is tightly attached to the wall of the working well, so that a closed space is formed. During the installation of the temporary gate, in order to ensure safety, the upstream pipe network pauses or reduces water, after the gate is installed, the upstream pipe network normally receives water, and the installation of the gate is controlled within 4 hours.
