In order to prevent rainwater from entering the underground garage or the first floor, flood-proof sandbags are generally used. During flood season, sandbags are piled at the door of the unit and the entrance and exit of the garage to achieve a certain water-stopping effect. However, sandbags need to occupy a large area of ​​storage space, and the strength after stacking is low, which is easy to leak; in addition, the stacking and storage of sandbags require manual labor, and the labor intensity is high. In order to overcome the defects of flood-proof sandbags, some waterproof threshold products have also appeared on the market, but they need to be drilled outside the wall for installation, and the tightness and firmness between them and the wall and the ground cannot be guaranteed.

In actual processing, the water stop plate can be made of stainless steel plate or galvanized steel plate, and the height of the water stop plate is 20-30 mm. Multiple water stop plates can be stacked together to meet the water blocking requirements during flood season. In order to ensure the sealing performance between the water stop plates and the sealing performance between the water stop plates and the ground, the top wall and the bottom wall of the water stop plate 3 are both provided with a second sealing strip 6 (horizontally arranged) with a hollow structure, and the second sealing strip has an installation plane for easy installation. At least two pairs of lock holes 7 are provided from top to bottom at the edges of each pair of inner guard plates 2b and outer guard plates 2a, and locking parts 8 for fixing the water stop plates 3 are inserted in the lock holes 7. The water retaining height can be adjusted according to the number of water stop plates 3. Two or more pairs of lock holes 7 are used to meet the locking requirements of the water stop plates at different water retaining heights.

[0022] During actual processing, the length of the water stop plate 3 is slightly larger than the spacing between the walls 1 , and the spacing between the connecting plates 2 c of the two door frames 2 is larger than the length of the water stop plate 3 , thereby achieving flexible installation and disassembly of the water stop plate 3 .
