Technical Field

[0001] The utility model relates to the technical field of multi-prism double-wall corrugated pipes, in particular to a multi-prism double-wall corrugated pipe. Background Art

[0002] The polygonal double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. The wave peak structure of the outer wall is designed as a polygonal prism structure, and the outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the pipe's resistance to soil load. It is often used in underground drainage pipes, etc.

[0003] When installing the traditional polygonal double-wall corrugated pipe, a rubber ring is put on the socket of one corrugated pipe, and then inserted into the socket of another corrugated pipe to connect the two corrugated pipes. However, in actual use, it is found that when the corrugated pipe is buried underground, the connecting port of the corrugated pipe is subjected to a large pressure from the soil, resulting in deformation and damage. At the same time, it is easy to shake during the burial process, which leads to a loose sealing connection of the corrugated pipe, resulting in a reduction in the sealing effect, affecting the use effect of the polygonal double-wall corrugated pipe.

The mounting plates in the same group are rotatably connected to a rotating shaft on one side close to each other, and a stabilizing plate is fixedly connected to the arc surface of the rotating shaft, and the cross-section of the stabilizing plate is "L" shaped.

[0016] The effect achieved by the above components is that the position of the protective device will be more stable and less likely to shift, thereby better protecting the installation interface of the bellows body from deformation and damage.

[0029] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment: the protective device 2 includes a first mounting frame 21 and a second mounting frame 22, and the surfaces of the first mounting frame 21 and the second mounting frame 22 are respectively fixedly connected with connecting blocks 24 on both sides, and the surfaces of the connecting blocks 24 are threadedly connected with bolts 25, and the inner walls of the first mounting frame 21 and the second mounting frame 22 are respectively fixedly connected with protective rings 23 on the sides close to each other, and the protective rings 23 are clamped on the arc surface of the corrugated pipe body 1. When the two corrugated pipe bodies 1 are installed underground and connected to each other, first, the interfaces of the two corrugated pipe bodies 1 are plugged into each other, and then the first mounting frame 21 is fixedly connected to the inner walls of the first mounting frame 21 and the second mounting frame 22. The protective ring 23 on the second mounting frame 22 is respectively clamped on the arc surface of the outer bellows body 1. At this time, the first mounting frame 21 and the second mounting frame 22 will contact and squeeze each other, and then the bolt 25 is threadedly connected with the connecting block 24, so that the first mounting frame 21 and the second mounting frame 22 are fixedly connected to each other. At this time, when the bellows body 1 is connected and installed, the installation interface will be more stable and not easy to shake during the burial process under the pressure of the soil, which ensures the firm sealing connection of the bellows, the sealing effect at the connection port, and the normal use of the bellows body 1.

[0030] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment: the two ends of the first mounting frame 21 are respectively fixedly connected with an insertion rod 26, and the two ends of the second mounting frame 22 are respectively provided with a slot 27, and the insertion rod 26 is plugged into the slot 27. Through the plug-in setting of the insertion rod 26 and the slot 27, the first mounting frame 21 and the second mounting frame 22 can be more stable and firm when connected and installed with each other, and are not prone to shaking, thereby improving the stability of the use of the protective device 2, and the inner wall of the protective ring 23 is fixedly connected with a reinforcement pad 211, and the reinforcement pad 211 is a rubber pad. Through the setting of the reinforcement pad 211, the friction force of the interface between the protective ring 23 and the corrugated pipe body 1 is further increased, thereby better protecting the interface.

Through the setting of the positioning rod 28, the position of the first mounting frame 21 and the second mounting frame 22 is more stable when buried in the ground, and it is not easy to deviate to the side, which affects the protection of the installation interface. One side surface of the first mounting frame 21 and the second mounting frame 22 are respectively fixedly connected with a clamping plate 210, and the clamping plate 210 is clamped on the surface of the corrugated pipe body 1. Through the setting of the clamping plate 210, when the first mounting frame 21 and the second mounting frame 22 are installed, the clamping plate 210 is clamped in the gap on the surface of the corrugated pipe body 1, so that the first mounting frame 21 and the second mounting frame 22 can be more stable.

[0032] Reference Figure 1 , Figure 2 and Figure 4 As shown, in the present embodiment: the stabilizing device 3 comprises four mounting plates 31, and the four mounting plates 31 are grouped in pairs, and the two groups of mounting plates 31 are respectively fixedly connected to the surfaces of the first mounting frame 21 and the second mounting frame 22, and the mounting plates 31 of the same group are rotatably connected to the side close to each other with a rotating shaft 32, and a stabilizing plate 33 is fixedly connected to the arc surface of the rotating shaft 32, and the cross-section of the stabilizing plate 33 is "L". When the protective device 2 is installed on the surface of the corrugated pipe body 1, the stabilizing plates 33 on both sides are rotated so that the rotating shaft 32 fixedly connected to the stabilizing plate 33 rotates on the mounting plate 31 until the stabilizing plate 33 is vertical to the first mounting frame 21 and the second mounting frame 22. Then, after the subsequent installation of the corrugated pipe and the backfilling of soil, the position of the protective device 2 will be more stable and less likely to deviate, thereby better protecting the mounting interface of the corrugated pipe body 1 from deformation and damage.

[0034] Working principle: When two bellows bodies 1 are installed underground and connected to each other, first, the interfaces of the two bellows bodies 1 are plugged into each other, and then the protective rings 23 on the first mounting frame 21 and the second mounting frame 22 are respectively clamped on the arc surface of the outer bellows body 1, and at the same time, the clamping plates 210 fixedly connected on the surfaces of the first mounting frame 21 and the second mounting frame 22 will be clamped in the gap on the surface of the bellows body 1. At this time, the first mounting frame 21 and the second mounting frame 22 will contact and squeeze each other, and then the bolts 25 are threadedly connected to the connecting block 24, so that the first mounting frame 21 and the second mounting frame 22 are fixedly connected to each other. At this time, when the bellows body 1 is connected and installed, the installation interface will be more stable and not easy to shake during the burial process under the pressure of the soil, which ensures the firm sealing connection of the bellows, the sealing effect at the connection port, and the normal use of the bellows body 1.

[0035] After the protective device 2 is installed on the surface of the bellows body 1, the stabilizing plates 33 on both sides are rotated to make the rotating shaft 32 fixedly connected to the stabilizing plate 33 rotate on the mounting plate 31 until the stabilizing plate 33 is in a vertical state with the first mounting frame 21 and the second mounting frame 22, and then the screw 35 is threadedly connected to the fixing plate 34 until the screw 35 is threadedly connected to the arc surface of the rotating shaft 32. After the installation of the bellows and the backfilling of soil are completed, the position of the protective device 2 will be more stable and less likely to shift, thereby better protecting the installation interface of the bellows body 1 from deformation and damage.
