Technical Field
[0001] The utility model relates to the technical field of concrete pipes, in particular to a corrosion-resistant concrete pipe. Background Art
[0002] Concrete pipe: English name concrete pipe. It is a pipe made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. It can be divided into four types: plain concrete pipe, ordinary reinforced concrete pipe, self-stressed reinforced concrete pipe, and prestressed concrete pipe.
[0003] Existing concrete pipes are generally fragile and will corrode after being buried underground for a long time. Concrete pipes usually need to be spliced together for use. Most concrete pipes are connected at one end through a connecting flange. Since concrete pipes have poor corrosion resistance, the flange connection will become loose after the concrete pipes are corroded, which will easily cause gaps and cause liquid in the pipe to leak out.

[0005] In view of the deficiencies in the prior art, the utility model provides a corrosion-resistant concrete pipe, which solves the problem that most concrete pipes are connected at one end by a connecting flange. Since the concrete pipe has poor corrosion resistance, the flange connection will become loose after the concrete pipe is corroded, which will easily cause gaps and cause liquid in the pipe to leak out.

The steel cylinder 3 is provided between the concrete pipe core 2 and the concrete interlayer 4, and has good corrosion resistance and can resist the erosion of various chemical substances, so that after the concrete pipe core 2 and the concrete interlayer 4 are corroded, the steel cylinder 3 protects the liquid from leakage, and the flange 7 and the steel cylinder 3 are designed as an integral part, so that the flanges 7 at both ends are connected to have an anti-corrosion effect, and thus the joints will not crack.
[0024] See also Figure 1-4 The utility model provides a technical solution: the steel cylinder 3 is located between the concrete pipe core 2 and the concrete interlayer 4. The steel cylinder 3 prevents liquid leakage after the concrete pipe core 2 is corroded.
[0025] See also Figure 1-4 The utility model provides a technical solution: the steel cylinder 3 is a circular anti-corrosion steel pipe. The steel cylinder 3 is an anti-corrosion steel pipe, which can effectively prevent or slow down the corrosion caused by chemical or electrochemical reactions during transportation and use.
[0026] See also Figure 1-4 The utility model provides a technical solution: the two ends of the concrete pipe core 2 are flush with the edge of the flange 7. The two ends of the concrete pipe core 2 are flush with the edge of the flange 7, so that the concrete pipe core 2 is butted after the flange 7 is connected, thereby reducing the gap.
[0027] See also Figure 1-4 The utility model provides a technical solution: the two ends of the concrete interlayer 4 and the anti-oxidation layer 6 are in contact with the flange 7. The two ends of the concrete interlayer 4 and the anti-oxidation layer 6 are in contact with the flange 7, so that the two ends of the concrete interlayer 4 and the anti-oxidation layer 6 are protected to prevent the edges of the concrete interlayer 4 and the anti-oxidation layer 6 from being bumped.
[0028] See also Figure 1-4 The utility model provides a technical solution: the anti-oxidation layer 6 is composed of an anti-oxidation coating. The anti-oxidation material has certain heat insulation, anti-oxidation and anti-corrosion protective effects, and prolongs the service life of the substrate.

The sealing gasket 10 makes the flange 7 play a sealing role after connection, thereby reducing the leakage at the joint.
[0030] During operation, the steel cylinder 3 is arranged between the concrete pipe core 2 and the concrete interlayer 4. The steel cylinder 3 has good corrosion resistance and can resist the erosion of various chemical substances. Therefore, after the concrete pipe core 2 and the concrete interlayer 4 are corroded, the liquid will not leak through the protection of the steel cylinder 3. The flange 7 and the steel cylinder 3 are designed as an integral whole, so that the flanges 7 at both ends have an anti-corrosion effect after being connected, and cracks will not appear at the joints.

[0031] In summary, this corrosion-resistant concrete pipe solves the problem that most concrete pipes are connected at one end through a connecting flange. Since the corrosion resistance of concrete pipes is poor, the flange connection will become loose after the concrete pipe is corroded, which will easily cause gaps and cause liquid leakage in the pipeline.
