Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an EPTU steady-state earthquake-resistant drainage pipe. Background Art

[0002] Drainage pipes play a very important role in daily production and life. Most of the existing corrugated drainage pipes on the market adopt a cylindrical structure. The cylindrical structure is easy to roll during installation and easy to shift during backfilling. Its stability during stacking, transportation and installation is poor. At the same time, since the pipe material is a cylindrical surface structure, it cannot bear a large pipe load. Based on this, it is particularly necessary to design a new type of EPTU steady-state earthquake-resistant drainage pipe. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide an EPTU steady-state earthquake-resistant drainage pipe, which has a simple structure, reasonable design, greatly improves the stability during stacking, transportation and installation, effectively bears the pipe load, has strong practicability and is easy to promote and use.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions: The EPTU steady-state earthquake-resistant drainage pipe includes a pipe body, a corrugated pipe wall and flat teeth. The pipe body is cylindrical. The two sides of the pipe body are pipe orifices convenient for clamp connection. The corrugated pipe walls are uniformly distributed along the axial direction of the outer periphery of the pipe body. Flat teeth are arranged at the bottom of the corrugated pipe walls. The pipe body, the corrugated pipe walls and the flat teeth are integrally formed by EPTU.

[0005] Preferably, the number of the flat teeth matches that of the corrugated pipe walls, and the flat teeth are correspondingly arranged at the bottom of the corrugated pipe walls; the bottom surface of the flat teeth is a rectangular plane, and the connecting surface between the bottom surface of the flat teeth and the vertical surface of the flat teeth is an arc surface.

[0006] Preferably, the cross-section of the corrugated pipe wall along the axial direction of the pipe body is a semi-circular surface.

[0007] The beneficial effects of the utility model: This device can improve the stability during stacking, transportation and installation, effectively bear the pipe load, has high reliability and broad application prospects. Description of the Drawings

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Referring to Figures 1-7 , the following technical solutions are adopted in this specific embodiment: an EPTU steady-state seismic drainage pipe, including a pipe body 1, a corrugated pipe wall 2 and flat teeth 3. The pipe body 1 is cylindrical, and both sides of the pipe body 1 are pipe orifices 4 for easy connection by a clamp. The corrugated pipe wall 2 is evenly distributed along the axial direction on the periphery of the pipe body 1. The bottom of the corrugated pipe wall 2 is provided with flat teeth 3. The number of flat teeth 3 matches that of the corrugated pipe wall 2, and the flat teeth 3 are correspondingly arranged at the bottom of the corrugated pipe wall 2.

[0018] In this specific embodiment, the pipe body 1, the corrugated pipe wall 2 and the flat teeth 3 are integrally formed by EPTU. Among them, the cross-section of the corrugated pipe wall 2 along the axial direction of the pipe body is a semi-circular surface, the bottom surface of the flat teeth 3 is a rectangular plane, and the connecting surface between the bottom surface of the flat teeth and the vertical surface of the flat teeth is an arc surface.

[0019] In this specific embodiment, the bottom of the pipe material adopts a rectangular plane structure, which can effectively bear the weight of the pipe material. At the same time, it will not roll during installation and will not shift during backfilling. When the drainage pipe is used, it is connected by a clamp, which can improve the stability and water tightness of the water pipe. Compared with the traditional socket connection method, the socket distance of each pipe of the drainage pipe under this connection structure can be reduced by up to 30 cm, effectively increasing the use length. This device greatly improves the stability of the drainage pipe during stacking, transportation and installation, and has broad market application prospects.

[0020] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will also have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
