前記両流体回収タンク１３内の流体はヒータ１８により加熱され、この流体がポンプ１４により流体回収タンク１３から接続管１５を通して流体供給管１１に供給されると、この流体供給管１１の各流体出口１２から出た流体が散水状態または噴霧状態で覆工コンクリート２の内周表面に吹き付けられる。覆工コンクリート２に付着せずに落下する流体は、流体回収トレー４で、底壁７や両側壁５，６を伝って回収樋１６に集まりヒータ１８に回収されたり、覆工コンクリート２の内周表面を伝って回収樋１７に集まりヒータ１８に回収されたり、開口８ａから直接落下してヒータ１８に回収され、そのヒータ１８により加熱されて流体回収タンク１３に戻される。このようにして回収された流体は再びポンプ１４により流体回収タンク１３から接続管１５を通して流体供給管１１に循環される。前記温度センサ１９は覆工コンクリート２の内周表面の温度を測定して前記コントローラ２０に出力する。コントローラ２０は、この覆工コンクリート２の実際温度に関する検出値と、予め記憶された覆工コンクリート２の養生温度に関する設定値とを比較し、その検出値が設定値になるように前記ヒータ１８を制御する。   When the fluid in both the fluid recovery tanks 13 is heated by the heater 18 and this fluid is supplied from the fluid recovery tank 13 through the connection pipe 15 to the fluid supply pipe 11 by the pump 14, each fluid outlet of the fluid supply pipe 11 is provided. The fluid which came out of 12 is sprayed on the inner peripheral surface of the lining concrete 2 in the state of watering or spraying. The fluid falling without adhering to the lining concrete 2 is collected by the fluid recovery tray 4 along the bottom wall 7 and the both side walls 5 and 6 in the recovery rod 16 and recovered by the heater 18, or inside the lining concrete 2 Along the circumferential surface, it collects in the recovery rod 17 and is recovered by the heater 18 or falls directly from the opening 8a and is recovered by the heater 18, heated by the heater 18 and returned to the fluid recovery tank 13. The fluid recovered in this manner is circulated again from the fluid recovery tank 13 to the fluid supply pipe 11 through the connection pipe 15 by the pump 14. The temperature sensor 19 measures the temperature of the inner peripheral surface of the lining concrete 2 and outputs it to the controller 20. The controller 20 compares the detected value related to the actual temperature of the lining concrete 2 with the preset value related to the curing temperature of the lining concrete 2 and sets the heater 18 so that the detected value becomes the set value. Control.

図の二点鎖線で示すようにヒータ１８を流体回収タンク１３の周りに設置してもよい。その場合、覆工コンクリート２に付着せずに落下する流体は、回収樋１６，１７や開口８ａからヒータ１８を通さずに流体回収タンク１３に直接落下し、流体回収タンク１３でこのヒータ１８により加熱される。なお、いずれのヒータ１８を採用した場合でも、流体回収タンク１３の周りを断熱材により覆った方が好ましい。   The heater 18 may be installed around the fluid recovery tank 13 as indicated by a two-dot chain line in the figure. In that case, the fluid that falls without adhering to the lining concrete 2 falls directly to the fluid recovery tank 13 without passing through the heaters 18 from the recovery rods 16 and 17 and the opening 8a. Heated. In addition, even when any heater 18 is employed, it is preferable to cover the fluid recovery tank 13 with a heat insulating material.
