Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a reinforced concrete pipe, comprising a supporting cement layer 1, a steel cylinder 2, a reinforcing ring 3, an inner cement mortar layer 4, a shaping net 5, an assembling groove 6, an assembling cylinder 7, a positioning cement mortar layer 8, a prestressed steel wire 9 and a cement mortar protective layer 10, a steel cylinder 2 is arranged in the supporting cement layer 1, an inner cement mortar layer 4 is arranged on the inner wall of the supporting cement layer 1, a shaping net 5 is preset on the inner side of the inner cement mortar layer 4, an assembling groove 6 is opened on the inner wall of one end of the inner cement mortar layer 4, an assembling cylinder 7 is arranged at the other end of the inner cement mortar layer 4, a positioning cement mortar layer 8 is arranged on the outer wall of the supporting cement layer 1, a prestressed steel wire 9 is pre-embedded in the positioning cement mortar layer 8, and a cement mortar protective layer 10 is arranged on the outer wall of the positioning cement mortar layer 8.

[0021] In this example, a reinforcement ring 3 is provided on the outer wall of the steel cylinder 2. The steel cylinder 2 and the reinforcement ring 3 are an integrated structure. The above structural design ensures that the structural strength of the steel cylinder 2 is sufficient and can improve the connection tightness between the steel cylinder 2 and the supporting cement layer 1, thereby ensuring that the supporting cement layer 1 has sufficient structural strength.

[0022] The reinforcement rings 3 are evenly spaced on the outer wall of the steel cylinder 2. Both the steel cylinder 2 and the reinforcement rings 3 are made of thin steel plates. The thickness of the reinforcement rings 3 is greater than half of the thickness of the steel cylinder 2. The above structural design increases the contact area between the supporting cement layer 1 and the steel cylinder 2, thereby improving the strength of the combination of the two.

[0023] The inner cement mortar layer 4 and the assembling tube 7 are an integrated structure, and the outer diameter of the assembling tube 7 is equal to the diameter of the assembling groove 6. The above structural design enables the assembling tube 7 to be stably connected to the assembling groove 6 when the reinforced concrete pipe is spliced.

[0024] The thickness of the shaping net 5 is greater than 1 / 4 of the thickness of the inner cement mortar layer 4. The shaping net 5 is made of fine stainless steel wire mesh. The above structural design improves the structural strength of the inner cement mortar layer 4 and ensures that the inner cement mortar layer 4 can withstand a large internal water pressure.

[0025] The prestressed steel wires 9 are wound in a ring shape in the positioning cement mortar layer 8. The prestressed steel wires 9 are densely arranged to fit each other. The above structural design further enhances the ability of the reinforced concrete pipe to resist external pressure, ensuring that the reinforced concrete pipe as a whole can work stably for a long time in deeper soil.

[0026] Working principle: When laying reinforced concrete pipes, align multiple reinforced concrete pipes, insert the assembly tube 7 at the end of the previous reinforced concrete pipe into the assembly groove 6 opened at the end of the next reinforced concrete pipe, and then use the existing connection and sealing means to process the connection;

[0027] During normal deep burial work, the supporting cement layer 1 and the steel cylinder 2 cooperate with the prestressed steel wire 9 and the cement mortar protective layer 10 to withstand the pressure of the external soil to ensure that the reinforced concrete pipe as a whole does not deform. The inner cement mortar layer 4 and the shaping net 5 stably withstand the internal water pressure to ensure that the reinforced concrete pipe as a whole can work stably for a long time. This is the working principle of the reinforced concrete pipe.
