[0028] When workers build a window-hole type protective wall on the slope to be constructed, they use the shaping device of this embodiment. Specifically, when starting to use it, the two arc frames 2 need to be rotated to a certain angle; then according to the angle between the two arc frames 2, the second leg 42 slides on the first leg 41, and the position of the second leg 42 on the first leg 41 is adjusted and fixed. At this time, the bolt passes through a first lock hole and a second lock hole to achieve the second leg 42 and the first leg 41 are fixedly connected together, and the first leg 41 and the second leg 42 are in an extended state. Generally, according to the size of the window-hole type protective wall to be built, one of the first lock holes is selected, and after the first lock hole and the second lock hole are fixedly connected by bolts and nuts, the first leg 41 and the second leg 42 are fixedly connected.

[0029] The second leg 42 is then fixed to one end of the arc frame 2, and then the column 1 and the first leg 41 are fixed on the slope to be constructed. The column 1, the first leg 41 and the second leg 42 support the two arc frames 2 and the support plate 3, and the support plate 3 supports construction materials such as stone slabs.

[0030] Since the structural shape and curvature of the arc frame 2 and the support plate 3 are fixed, construction materials such as stone can be constructed according to the structural shape of the arc frame 2 and the support plate 3. The shaping device of this embodiment ensures that the arc line of the constructed window-hole type protective wall is good and meets the manufacturing requirements. At the same time, the angle between the two arc frames 2 of this embodiment can be adjusted to meet the requirements of manufacturing window-hole type protective walls of different shapes and sizes, and has a wide range of applications.
