[0024] In this embodiment: During the actual use of the installation wall 2, it is preset on the left and right sides of the roadway. The lower fire prevention board 103 is moved into the installation guide rail 4 through the side opening of the installation guide rail 4. Then, a plurality of spaced fire prevention boards 102 are sequentially moved into the installation guide rail 4. Finally, the upper fire prevention board 101 is moved in. Through the settings of the docking groove 105 and the docking block 104, the connection stability between the upper fire prevention board 101, the spaced fire prevention board 102 and the lower fire prevention board 103 can be improved. Moving blocks 5 are fixedly connected to one side of the spaced fire prevention board 102 and the lower fire prevention board 103.
