One end of the main water baffle 2 is hinged to the main hinge seat 7 through a main hinge 8. A main hinge seat sealing strip 9 is provided on the main hinge seat 7 to match the main water baffle 2. One end of the auxiliary water baffle 3 is hinged to the inner side of the main water baffle 2 through an auxiliary hinge 10. The main water baffle 2 is provided with an auxiliary water baffle retracting pin 12 to match the other end of the auxiliary water baffle 3. An inter-plate sealing strip 15 is provided between two adjacent water baffle assemblies, and the inter-plate pin 11 is located on the drainage section of the main water baffle 2. A drainage section limiting step 13 matching the drainage section is provided on the front side of the intercepting ditch 1, and a water retaining section limiting step 14 matching the water retaining section is provided on the rear side of the intercepting ditch 1. The main hinge seat 7 is fixed on the water retaining section limiting step 14.

[0028] A method for using a multi-level water retaining plate structure for an underground entrance and exit, comprising the following steps: when water retaining is not required, an auxiliary water retaining plate is folded inside a main water retaining plate, the main water retaining plate is mounted on a diversion ditch, the outermost water retaining plate assembly is connected and fixed to a cover-tightening pin hole via a pin, and water is drained via a drainage hole; when water retaining is required, the pins on the outermost water retaining plate assembly and the cover-tightening pin hole are pulled out, the main water retaining plate is flipped open to a water retaining position and fixed via a water retaining position fixing frame, and then the auxiliary water retaining plate is flipped open to increase the water retaining height.

[0029] The present invention is mainly used in underground entrances and exits of various underground motor vehicle garages, non-motor vehicle garages and underground storage spaces. Since the underground entrances and exits often have a certain slope, rainwater is easily poured in, causing various safety hazards. The number of auxiliary water retaining plates of the present invention can be appropriately adjusted according to the height of the underground entrances and exits. If it is necessary to increase the number of auxiliary water retaining plates, it is only necessary to hinge another auxiliary water retaining plate at the end of the auxiliary water retaining plate. When the current auxiliary water retaining plate is flipped over to the water retaining position, continue to flip over the next auxiliary water retaining plate. Under the premise that the height of the underground entrance and exit allows, the water retaining height can be continuously increased.

[0030] The present invention does not normally affect vehicle traffic and drainage. When the outdoor heavy rain reaches the flooding water level, the water retaining plate structure can be flipped open to retain water. A multi-level water retaining structure combining a main water retaining plate and an auxiliary water retaining plate is adopted, so that it can meet the water retaining needs of different water levels, thereby effectively preventing rainwater from entering the basement and reducing safety hazards.
