[0029] Example

[0030] Please refer to Figures 1-3 This utility model provides a high-pressure-resistant anti-detachment galvanized steel skeleton spiral pipe, including skeleton pipe layer 1, plastic pipe layer 2, arc-shaped buckle 3, support pipe layer 4, and support rib frame 5.

[0031] Furthermore, the skeleton pipe layer 1 is a galvanized steel skeleton pipe, which reduces deformation by utilizing the rigid structure. The skeleton pipe layer 1 is covered with a plastic pipe layer 2, which extends the service life of the pipeline by utilizing the corrosion resistance of the plastic pipe layer 2.

[0032] Among them, a support pipe layer 4 is provided between the plastic pipe layer 2 and the skeleton pipe layer 1. The support pipe layer 4 is connected to the skeleton pipe layer 1 through support ribs 5. Several support ribs 5 are provided between the support pipe layer 4 and the skeleton pipe layer 1. The several support ribs 5 are evenly arranged along the pipe length direction of the skeleton pipe layer 1.

[0033] Because anti-detachment galvanized steel skeleton spiral pipes are generally used for municipal drainage and industrial wastewater discharge, they need to be buried underground to transport high-temperature and high-pressure corrosive wastewater. Therefore, under the pressure of the soil outside the pipe and the excessive water pressure of the water flow inside the pipe, the pipe is easily squeezed and broken. Moreover, at high temperatures, the plastic pipe layer 2 is prone to thermal expansion and separation from the skeleton pipe layer 1.

[0034] Preferably, the support ribs 5 are used to support the pipe against excessive pressure from the inside and outside of the pipe by being arranged between the skeleton pipe layer 1 and the plastic pipe layer 2; the support ribs 5 are arranged on a support pipe layer 4, and the entire support surface of the support pipe layer 4 is used to bear and share the pressure, so as to avoid excessive pressure, extrusion and deformation of the outer soft plastic pipe layer 2 at the support ribs 5, and even breakage and loss of the pressure resistance.

[0035] Further, the support ribs 5 include limiting grooves 503, which are close to the skeleton pipe layer 1 and on which the arc-shaped two ends of the arc-shaped buckles 3 are respectively slidably abutted. When the arc-shaped top end of the arc-shaped buckle 3 is extruded, the arc-shaped buckle 3 will be bent and deformed, so that the arc-shaped two ends slide in the limiting grooves 503, and the arc-shaped height of the arc-shaped plate 403 is reduced.

[0036] Among them, the arc-shaped two ends of the arc-shaped buckle 3 are bent and arranged, and the bent ends are abutted with the groove surface of the limiting groove 503, so as to increase the elastic performance of the arc-shaped buckle 3 and increase the bending deformation amplitude.

[0037] Please refer to Figure 3 In this embodiment, the support pipe layer 4 includes a support ring plate 401, a groove plate 402, and an arc-shaped plate 403.

[0038] Specifically, the support ring plate 401 is correspondingly connected with the support ribs 5, the groove plate 402 is fixed at both ends of the support ring plate 401 on the adjacent support ribs 5, and the groove plate 402 is matched with the arc-shaped end of the arc-shaped buckle 3.

[0039] The plastic pipe layer 2 includes a plastic pipe 201 and a groove 202.

[0040] The plastic pipe 201 is fixedly provided with a plurality of grooves 202, and the plurality of grooves 202 are uniformly arranged along the length direction of the pipe. The groove 202 corresponds to the groove plate 402 one by one, and the groove 202 is matched with the groove plate 402.

[0041] Preferably, the arc-shaped end of the arc-shaped buckle 3 is matched with the arc-shaped end of the groove plate 402 of the support pipe layer 4, and the arc-shaped end of the groove plate 402 of the support pipe layer 4 is matched with the arc-shaped end of the groove 202 of the plastic pipe layer 2, so as to prevent the plastic pipe layer 2 from being separated from the support pipe layer 4 and the skeleton pipe layer 1 due to thermal expansion, improve the stability of the pipe structure, and when the plastic pipe layer 2 is externally pressed, the force acting on the groove 202 will act on the groove plate 402 and the arc-shaped buckle 3, the arc-shaped structure of the groove plate 402 and the arc-shaped buckle 3 is used to support with higher strength, and when the pressure is too high, the groove plate 402 and the arc-shaped buckle 3 can increase the stress by bending and deforming, so as to avoid excessive rigidity and breakage. The groove plate 402 is made of soft plastic structure.

[0042] In addition, two ends of the arc-shaped plate 403 in the support pipe layer 4 are fixedly surrounded on the support ring plate 401, and the arc-shaped top end of the arc-shaped plate 403 abuts against the inner wall of the plastic pipe 201.

[0043] The arc-shaped height of the arc-shaped plate 403 is less than the arc-shaped height of the groove plate 402.

[0044] Preferably, when the pipeline is normally working, the groove 202 of the plastic pipe 201 is elastically deformed and supported by the arc-shaped buckle 3, and the inner wall of the plastic pipe 201 is hard supported by the fixed arc-shaped plate 403. At this time, because the arc-shaped height of the arc-shaped plate 403 is less than the arc-shaped height of the groove plate 402, the arc-shaped buckle 3 is mainly used for soft support at first, and when the pressure gradually increases, the pressure is then shared to the arc-shaped plate 403 for hard support.

[0045] When the pipeline bears too large pressure, the plastic pipe 201 will deform the arc-shaped buckle 3, so that the arc-shaped height of the arc-shaped buckle 3 is reduced to the arc-shaped height of the arc-shaped plate 403, so that the too high pressure is hard supported by the arc-shaped plate 403 to avoid the arc-shaped buckle 3 from being deformed too much and broken. When the too high pressure is reached, in order to protect the normal transportation function of the pipeline, the arc-shaped plate 403 will be broken under the too high pressure, so that the plastic pipe 201 abuts against the surface of the support ring plate 401, and is supported by the support frame 5 with stronger supporting effect, so as to maintain the normal transportation function of the pipeline under the too high pressure, reduce the problem that the pipeline is quickly leaked and damaged after the plastic pipe layer 2 is broken, and provide a buffer time for maintenance of the rescue construction personnel.

[0046] Further, in the embodiment, the support frame 5 further includes a connecting ring plate 501, a welded bottom plate 502, a rib 504, and a protrusion 505.

[0047] Specifically, one end of the connecting ring plate 501 is fixedly connected to the support ring plate 401, and the other end of the connecting ring plate 501 is fixedly connected to the welded bottom plate 502, which is fixedly connected to the outer wall of the skeleton pipe layer 1. The connecting ring plate 501 is hollow inside, and a plurality of ribs 504 are fixedly arranged in the hollow inside, and each rib 504 is inclined relative to the inner wall of the connecting ring plate 501.

[0048] The hollow inside reduces the weight of the connecting ring plate 501, thereby reducing the weight of the pipeline, and the inclined rib 504 can increase the stability of the connecting ring plate 501, so as to ensure that it can bear greater force.

[0049] In addition, the welded bottom plate 502 is fixedly provided with the protrusion 505 on the plate surface connected to the skeleton pipe layer 1, and the outer wall of the skeleton pipe layer 1 is provided with a ring-shaped groove which is one-to-one correspondingly matched with the protrusion 505.

[0050] By the clamping of the convex 505 and the annular groove, the convex 505 bears the force from the pipeline axis direction, avoids the welding bottom plate 502 from separating from the skeleton pipe layer 1, and increases structural stability.

[0051] Thus far, the various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions of the present application according to the above description, and the scope of the present application is defined by the appended claims.
