t−設置しておく。Next, using the bracket (6), install two rails for pulling out the spare gate support girder (not shown), and place a hand-rolling machine winch (not shown) on the paper length line of this rail as the drawer lowering equipment ( 9). In this state, assemble the preliminary gate support girder. This ground assembly is Cape μ Crane (5)
This is done by sequentially integrating items that have been transported in small quantities. Once the preliminary gate support girder α1 has been assembled, pull out the support girder αO in the direction of the arrow (to) using the two rails mentioned above and the winch (9) for the manual rolling mill. A hand stretching machine (not shown) having a truss structure is attached to the tip of the support girder αQ. Also, a jacking device (not shown) is installed on the bracket (6).
t-set it up.

This gate (3) is also on the upstream side.
It will be passed in the horizontal direction corresponding to the width direction of.
これとともに、前述の軌条を受桁α0の下から取出す。At the same time, the aforementioned rail is taken out from under the support girder α0.

The pillars αη are arranged in multiple stages in the width direction of the gate (3), and are provided so that their lower ends reach the bottom of the waterway (2). A plate-shaped preliminary gate (to) is arranged between adjacent columns α9, and this preliminary gate (to) blocks water on the upstream side of the gate (3).
第1図〜第3図はこのときの状態を示している。FIGS. 1 to 3 show the state at this time.
ここで、水圧により生じる荷重は、予備ゲート支柱受桁

め、工事費程度は簡単に捻出することが可能となる。In this way, when removing the existing gate (3) or installing a new gate, it becomes possible to drive the reserve gate (to), making the removal and installation work easier. I can do it. In addition, by installing a preliminary gate (to), construction can be carried out without lowering the water level, and there is no need to stop power generation, etc., so the economic benefits can be extremely large. . Therefore, the construction costs can be easily recovered.
新ゲートが据付けられたなら、上記とは逆の手順で仮設
