を据付位置に据付けるものである。Means for Solving the Problems In order to solve the above problems, the present invention temporarily closes off the downstream side of the existing gate with a closed structure in the water gate with a first preliminary gate, and balances the water pressure upstream and downstream. The gate is floated, the existing gate that has been floated is pulled upstream 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. Then, the second preliminary gate is installed again and temporarily closed, and the second preliminary gate is opened by opening the first preliminary gate.
The downstream side of the preliminary gate will be drained, and the new gate will be installed at the installation location.

圧バランスさせる。 Next, a method for replacing the existing gate 4 with a new gate will be explained in detail. First, as shown in FIG. 2, a door groove 11 is made on the side surface of the concrete wall 2 on the downstream side of the gate 4, and a first preliminary gate 12 is installed. As a result, the downstream side of the gate 4 is temporarily closed, so water is injected between the gate 4 and the preliminary gate 12 to balance the water pressure upstream and downstream of the gate 4.
その後、ゲート４と戸溝５との係合を解き、第
３図に示すようにゲート４を浮上させて、大ブロ
ックのまま上流側へ引き出す。 Thereafter, the engagement between the gate 4 and the door groove 5 is released, the gate 4 is floated as shown in FIG. 3, and the large block is pulled out to the upstream side.
ゲート４が撤去されたなら、第４図に示すよう

当りを改造する。 Once the gate 4 has been removed, as shown in FIG. 4, the area upstream of the gate installation position 13 is temporarily closed off with a second preliminary gate 14. This second preliminary gate 14 is installed using the preliminary gate support girder 7 after the gate 4 is removed. Thereafter, the first preliminary gate 12 is opened to drain water downstream from the second preliminary gate 14, and the door stop is remodeled to accommodate the new gate.
次に再び第１の予備ゲート１２を仮締切し、第
５図に示すように第２の予備ゲート１４を取外し

ゲート１４を撤去して、工事が完了する。 Once the new gate 15 has been transported to the gate installation position 13, the second preliminary gate 14 is again installed and temporarily closed, as shown in FIG.
The new gate 15 will be drained and the new gate 15
Install by engaging the Further, the first preliminary gate 12 is removed, and after the installation is completed, the second preliminary gate 14 is removed to complete the construction.
このように第１および第２の予備ゲート１２，
