Embodiment Construction
[0031] In conjunction with the accompanying drawings, the comparative invention is further described.
[0032] When filling in the tunnel formed by roof 1, base plate 2 and surrounding rock 3, first determine the position of the lower formwork 11, dig out the groove of the flange plate of the lower formwork 11 on the base plate 2, and place the lower formwork 11 on the side The side is fixed by the side anchor rod 6, and then the middle formwork 10 and the upper formwork 9 are placed and fixed in sequence; the position of the I-shaped formwork is determined according to the length of the side formwork and the position of the fixing bolt hole 8, and the lower I-shaped formwork is excavated on the bottom plate 2. Place the lower I-shaped formwork 17 in the groove of the flange plate of the formwork 17, fix it through the side anchor rod 6, and then place and fix the middle I-shaped formwork 16 and the upper I-shaped formwork 15; determine the end formwork and side formwork And t...
