[0042] During specific operation, it mainly includes a sliding restraint support 1-2, a guide square steel beam 1-3 and a double roller screed plate 1-4. The sliding restraint support 1-2 is placed on the protective wall formwork 1-1, and at the same time, the sliding wheel 3-2 on the U-shaped card plate 2-3 is close to the top surface of the protective wall formwork 1-1. After the sliding restraint supports 1-2 at both ends are placed in place, the guide square steel beam 1-3 is installed and its two ends pass through the guide ring 2-2 in the guide support module 2-1 on the upper part of the sliding restraint support, and the specific position of the sliding restraint support 1-2 is adjusted to ensure that both ends of the guide square steel beam 1-3 pass through the guide ring 2-2. After the guide square steel beam 1-3 is installed in place, the locker 2-5 is rotated to make the rubber pad 4-1 close to the side wall of the protective wall formwork 1-1 to fix the position of the sliding restraint support 1-2.
