In the course of pouring the concrete 450, it is poured at an accurate height so that the surface of the third fastening groove 430 is exposed.

Then, as shown in FIGS. 3d and 3e, the third side wall FRP cover panel 460 is assembled to the upper surface of the three side wall FRP frame 410 in which the concrete 450 is placed, and the concrete 450 is cured . 3F, the third sidewall FRP cover panel 460 has a structure in which the hybrid jig 462 is formed, and an exposure groove 461 for exposing the third fastening groove portion 430 is formed .

Next, the upper FRP-concrete hybrid panel 600 is manufactured. This step is basically the same as the step of manufacturing the other hybrid panel described above, as shown in Figs. 4A to 4F. However, the upper FRP frame 610 has a manhole 601 formed therein as shown in FIG. 4A. The upper FRP frame 610 is also provided with a fourth fastening groove portion 620 at a position corresponding to the second and third fastening groove portions 230 and 430.

Since the remaining steps are substantially the same as those of other hybrid panel fabrication steps, a repetitive description thereof will be omitted.

When the hybrid panels 100, 200, 300, 400, 500, and 600 are completed, the valve room is constructed at the construction site. This step begins with the step of installing the bottom FRP-concrete hybrid panel 100, as shown in FIG. 5A. The bottom FRP-concrete composite panel 100 is installed on the bottom surface excavated to construct the valve chamber. Of course, preliminary work on the bottom surface may be performed before installing the bottom FRP-concrete hybrid panel 100.

Then, as shown in Fig. 5B, the step of installing the pipe 10 proceeds. Of course, this step will be omitted at the construction site where the piping 10 is installed.

Next, as shown in FIG. 5C, the step of installing the third and fourth side wall FRP-concrete hybrid panels 400 and 500 to face each other is performed on the bottom FRP-concrete hybrid panel 100. The third and fourth sidewall FRP-concrete hybrid panels 400 and 500 are installed to stand facing each other and are fastened using the first fastening recess 120 and the third fastening recess 230.
