Then, the upper gasket 16 is sleeved into the upper segment bolt 12, and the upper segment bolt 12 is fixed with one end of the water-stopping segment screw rod 13 by screwing. At this time, the hollow square tube 11 is horizontally erected above one side of the reserved hole, so that the upper segment bolt 12 and the water-stopping segment screw rod 13 penetrate through the hollow square tube 11 from top to bottom, and the entire assembly is suspended in the hole by using the upper segment nut 121. On the other side of the bottom of the reserved hole, the pre-cut bottom formwork 18 is placed, and the lower segment bolt 15 sleeved with the lower gasket 17 is threaded through the through hole of the bottom square tube 14 and connected with the other end of the water-stopping segment screw rod 13. By simultaneously tightening the upper segment bolt 12 and the lower segment bolt 15, the hollow square tube 11 and the bottom square tube 14 form a rigid clamping structure on the upper and lower sides of the hole. Finally, in the fastened state, the bottom formwork 18 is tightly attached to the bottom surface of the hole, and the overall device constitutes a stable stress frame.
