[0022] Combined with appendix Figs. 1-2 A reinforced concrete pipe with a leak-proof connection structure includes a pipe body 1. The pipe body 1 has connection ends on both sides. Each connection end includes a first connection end 11 and a second connection end 12. Several pipe bodies 1 are connected sequentially through the first connection end 11 and the second connection end 12. A buffer film 3 is provided between the first connection end 11 of one pipe body 1 and the second connection end 12 of an adjacent pipe body 1. A socket ring 110 is fitted on the outside of the first connection end 11, and a spigot ring 120 is fitted on the outside of the second connection end 12.
[0023] When two adjacent pipe bodies 1 are connected, the socket ring 110 of one of the pipe body 1 connection ends 12 is inserted into the socket ring 120 of the adjacent pipe body 1 connection end 11.
[0024] The socket ring 110 is provided with several limiting rings 111, and the inner side of the socket ring 110 is provided with a water-swellable rubber strip 112.
[0025] The socket ring 110 has a flared opening 113 at one end and a limiting end 114 at the other end away from the flared opening 113. The flared opening 113 facilitates the alignment and insertion of the insertion ring 120, improving assembly efficiency. The limiting end 114 is an inclined surface that slopes outward from the socket ring 110, serving as an auxiliary limiting function. Together with the limiting ring 111, it effectively fixes the socket ring 110 to the connecting end 11, preventing the socket ring 110 from moving or loosening.
[0026] The water-swellable rubber strip 112 is disposed between the two limiting rings 111.
[0027] The connecting end one 11 is provided with a limiting groove 50 and a rubber strip mounting groove 51, and the limiting groove 50 is matched with the limiting ring 111. In the embodiment, the limiting groove 50 and the limiting ring 111 are semicircular, and the limiting ring 111 is closely combined with the limiting groove 50; the rubber strip mounting groove 51 is used for arranging the water-swelling rubber strip 112.
[0028] The socket ring 120 is provided with a plurality of sealing grooves 121, and the sealing rubber strips 122 are arranged in the sealing grooves 121. In the embodiment, the sealing rubber strips 122 and the sealing grooves 121 are provided with two groups, and a single group or multiple groups can also be arranged.
[0029] One end of the socket ring 120 is provided with a flat end 123, and the other end of the socket ring 120 away from the flat end 123 is provided with a bent end 124. The bent end 124 is used for protecting the edge of the pipe end, and preventing damage caused by collision during transportation.
[0030] The connecting end two 12 is provided with a plurality of sealing inner grooves 60, and the sealing inner grooves 60 are matched with the sealing grooves 121.

[0031] The socket ring 110 and the socket ring 120 can be made of ordinary steel plate or stainless steel material, and appropriate materials can be selected according to the scene of drainage. When the drainage pipe is used for draining rainwater, the ordinary steel plate can be used to reduce the cost, and when the drainage pipe is used for draining sewage, the stainless steel material can be selected to improve the corrosion resistance of the pipe connecting structure; the limiting ring 111 on the socket ring 110 and the sealing groove 121 on the socket ring 120 are integrally formed by stamping processing, and the socket ring 110 and the socket ring 120 are made of steel belt welding; after the socket ring 110 and the socket ring 120 are made, they can be fixed in the pipe production mold to complete the production of the pipe.
