[0016] Example 1 like Figure 1-5 As shown, a prefabricated manhole cover piping cover includes a manhole frame 1, a removable manhole cover 2 inside the manhole frame 1, and a removable piping cover 3 on top of the manhole cover 2. The manhole cover 2 is provided with a flip-over overflow flap 205 above it, and a connecting groove 202 is provided on the outside of the overflow flap 205. The piping cover 3 includes a cover body 301. The top of the cover body 301 is provided with a top hole 305 and the bottom of the cover body 301 is provided with a bottom hole 309. An inserting ring 306 is provided on the outside of the bottom hole 309. The inserting ring 306 is used to connect with the connecting groove 202.

[0017] In the preferred embodiment, the well frame 1 includes a bottom frame 101, a side frame 102 is provided above the bottom frame 101, and a placement hole 103 is provided in the inner circle of the side frame 102. The placement hole 103 is used to place the well cover 2, and a limiting step 104 is provided inside the placement hole 103 to hold the well cover 2 in place.

[0018] In the preferred embodiment, the edge of the connecting groove 202 is provided with a plurality of slots 203, and the inner side of the connecting groove 202 is also provided with a limiting groove 208; A removable sealing strip is provided in the connecting groove 202.

[0019] In the preferred embodiment, a flip support plate 207 is provided on one side of the overflow flap 205, and a pin shaft is provided between the flip support plate 207 and the manhole cover 2 for rotatable connection.

[0020] In the preferred embodiment, the overflow flap 205 is provided with multiple through return holes 206, which are used to guide the water flow inside the piping cover 3 to the bottom of the manhole cover 2.

[0021] In the preferred embodiment, the outer side of the cover 301 is provided with multiple handles 302, which facilitate the disassembly of the cover 301.

[0022] In the preferred embodiment, the hood 301 has an internal cavity 308 for filling with gas, and a gas filling pipe 303 is provided below the hood 301 for filling the cavity 308 with gas. The gas filling pipe 303 is provided with a one-way valve.

[0023] In the preferred embodiment, the material of the cover 301 is rubber.

[0024] In the preferred embodiment, the top edge of the cover 301 is also provided with a plurality of evenly distributed overflow holes 304, which are used to drain excess water flow from the piping cover 3.

[0025] In the preferred embodiment, the outer circumferential edge of the embedded ring 306 is provided with multiple buckles 307, which fit into the limiting groove 208; The clip 307 is used to hold the embedded ring 306 out of the connecting groove 202.

[0026] The following is the usage method of a prefabricated manhole cover piping cover: The installation process is as follows: Inflate the cavity 308 inside the cover 301 through the air filling pipe 303. The one-way valve prevents air leakage. After the rubber cover 301 expands, it enhances the structural stability. Then, fix the bottom frame 101 of the manhole frame 1 to the manhole opening. The limiting step 104 in the placement hole 103 of the frame 102 supports the manhole cover 2. When installing the piping cover 3, first remove the sealing strip in the connecting groove 202. Hold the handle 302 on the outside of the cover 301 and align the bottom embedded ring 306 with the connecting groove 202 on the outside of the overflow flap 205 on the manhole cover 2. Make the buckle 307 on the outer circle of the embedded ring 306 fit with the limiting groove 208 on the inner side of the connecting groove 202. Press the buckle 307 to complete the snap-fit. The piping response process is as follows: When piping occurs, water flows from below the manhole cover 2 and impacts the overflow flap 205, causing it to rotate and open around the pivot pin between the flip support plate 207 and the manhole cover 2. Water flows through the bottom hole 309 into the interior of the cover 301. Part of the water is guided back to below the manhole cover 2 through the return hole 206 of the overflow flap 205. Excess water flows out through the overflow hole 304 at the top edge of the cover 301. The top hole 305 can balance the internal and external air pressure. The disassembly process is as follows: Hold the handle 302 and rotate the buckle 307 to disengage it from the slot 203 and limit the groove 208. Then, install the sealing strip in the connecting groove 202 and pull it up to remove the piping cover 3. Then, release the gas in the cavity 308 through the gas filling pipe 303. If the manhole cover 2 needs to be repaired, it can be directly removed from the placement hole 103. The manhole cover 2 and the placement hole 103 are also connected by rotating buckles. The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
