[0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage, etc. Drainage pipes are divided into plastic drainage pipes, concrete pipes and reinforced concrete pipes. Specifically, when designing plastic drainage pipes, current drainage pipes are usually extruded in one piece, which results in the drainage pipes themselves having average impact resistance and use strength, making it difficult to adapt to use in high-impact strength environments with large water flow rates. Utility Model Content

[0003] The purpose of the present invention is to provide a high-impact modified alloy octagonal structure wall drainage pipe in order to solve the above problems. An inner liner tube with a regular octagonal cross-sectional shape is coaxially sleeved on the inner periphery of the outer cover tube, so that the drainage pipe structure composed of the outer cover tube and the inner liner tube can have an octagonal drainage channel, which is convenient for using the inner liner tube to improve the impact resistance of the drainage pipe structure and ensure that it can adapt to high-impact strength environments with large water flow velocities. At the same time, it is convenient to use the octagonal drainage channel to reduce the impact energy of water flow collision. See below for details.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The high-impact modified alloy octagonal structure wall drainage pipe provided by the utility model comprises an outer cover pipe and an inner liner pipe, the axes of the outer cover pipe and the inner liner pipe are both arranged in the longitudinal direction, the inner liner pipe is coaxially sleeved on the inner circumference of the outer cover pipe, and the inner liner pipe is arranged with the same length as the outer cover pipe, so that the outer cover pipe and the inner liner pipe form a drainage pipe structure;

[0006] Both ends of the drainage pipe structure composed of the outer cover pipe and the inner lining pipe are coaxially and detachably assembled with pipe joint components, which are used to combine and connect adjacent drainage pipe structures through the pipe joint components.

[0007] Preferably, the outer cover tube is a PVC tube, the inner liner tube is a modified alloy tube with a regular octagonal cross-section, and the outer cover tube and the inner liner tube are coaxially combined by interference fit.

[0008] Preferably, the pipe joint assemblies include a matching sleeve, a flange plate and a clamping member. Both ends of the drainage pipe structure formed by the outer cover pipe and the inner liner pipe are sleeved with the matching sleeve in a coaxial sliding fit manner. The outer end faces of the matching sleeves are coaxially fixed with the flange plates. At the same time, the middle part of the matching sleeves is provided with a liquid passage opening corresponding to the pipe mouth of the inner liner pipe. The periphery of the matching sleeves is fixed with a plurality of wing seats extending radially outward, and the outer end faces of the wing seats away from the corresponding flange plates are longitudinally fixed with tensioning bolts through mounting sleeves. The outer cover pipes are coaxially fixed with the clamping member at the outer peripheral position of the end near the matching sleeve, and the periphery of the clamping member is fixed with a plurality of connecting seats extending radially outward, and the connecting seats and the wing seats are respectively matched front and back. The tensioning bolts pass through the corresponding connecting seats in a longitudinal sliding fit manner, and the parts passing through the connecting seats are coaxially engaged with locking nuts, and the locking nuts are pressed against the outer end faces of the corresponding connecting seats.

[0009] Preferably, the liquid passage openings are all as large as the corresponding pipe openings of the liner pipe.

[0010] Preferably, the tightening bolt and the mounting sleeve are combined and connected by threaded fitting.

[0011] Preferably, the clamp members are clamp structures in which the upper and lower parts are clamped together and bolts are inserted and installed on both sides.

[0012] Preferably, the number of the wing seats and the connecting seats are four and they are evenly distributed in the circumferential direction. At the same time, the wing seats and the connecting seats are staggered with each other at the two sides of the clamping member.

[0013] Preferably, the inner periphery of the mating sleeve is coaxially slidably fitted with a sealing gasket, the sealing gasket is located between the flange plate and the pipe opening of the outer cover pipe, and the inner periphery opening of the sealing gasket is the same size as the corresponding pipe opening of the inner liner pipe.

[0014] The above-mentioned high-impact modified alloy octagonal structural wall drainage pipe is used. Specifically in actual use, since the inner liner tube with a regular octagonal cross-sectional shape is coaxially sleeved on the inner periphery of the outer cover tube, the drainage pipe structure composed of the outer cover tube and the inner liner tube can have an octagonal drainage channel, which is convenient for using the inner liner tube to improve the impact resistance of the drainage pipe structure and ensure that it can adapt to high-impact intensity environments with large water flow rates. At the same time, it is convenient to use the octagonal drainage channel to reduce the impact energy of water flow collision, which is beneficial to further improve the impact resistance of the drainage pipe structure. Since both ends of the outer cover tube and the inner liner tube can be detachably assembled and installed with the pipe joint assembly, the tightening bolts are then passed through the connecting seat. The method of installing the locking nut later can quickly combine the matching sleeve and the flange plate at the end positions of the outer cover pipe and the inner liner pipe and tighten them. At the same time, the matching sleeve and the flange plate can be axially separated from the end positions of the outer cover pipe and the inner liner pipe by simply unscrewing the locking nut. The combination and disassembly of the matching sleeve and the flange plate at the end positions of the outer cover pipe and the inner liner pipe are simple and easy to implement, which is convenient for combining the matching sleeve and the flange plate at the end positions of the outer cover pipe and the inner liner pipe to connect the adjacent drainage pipe structures, and is also convenient for replacing and maintaining the sealing gasket after the matching sleeve and the flange plate are subsequently disassembled from the end positions of the outer cover pipe and the inner liner pipe.

[0015] The beneficial effects are as follows: 1. The utility model is provided with an inner liner tube with a regular octagonal cross-section on the inner periphery of the outer cover tube, so that the drainage pipe structure composed of the outer cover tube and the inner liner tube can have an octagonal drainage channel, which is convenient for improving the impact resistance of the drainage pipe structure with the help of the inner liner tube, ensuring that it can adapt to high-impact environments with large water flow velocities. At the same time, it is convenient to use the octagonal drainage channel to reduce the impact energy when the water body flows and hits, which is conducive to further improving the impact resistance of the drainage pipe structure.

[0016] 2. Both ends of the outer cover pipe and the inner liner pipe can be removably assembled and installed with pipe joint assemblies.

[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-6As shown, the utility model provides a high-impact modified alloy octagonal structure wall drainage pipe, including an outer cover pipe 2 and an inner lining pipe 4, the axes of the outer cover pipe 2 and the inner lining pipe 4 are both arranged longitudinally, the inner lining pipe 4 is coaxially sleeved on the inner periphery of the outer cover pipe 2, and the inner lining pipe 4 is arranged at the same length as the outer cover pipe 2, so that the outer cover pipe 2 and the inner lining pipe 4 constitute a drainage pipe structure. Specifically, the outer cover pipe 2 is a PVC pipe, and the inner lining pipe 4 is a modified alloy pipe with a regular octagonal cross-sectional shape, and the outer cover pipe 2 and the inner lining pipe 4 are coaxially combined by interference fit. The effect of such an arrangement is that the drainage pipe structure composed of the outer cover pipe 2 and the inner lining pipe 4 can have an octagonal drainage channel, which is convenient for using the inner lining pipe 4 to improve the impact resistance of the drainage pipe structure, and at the same time, it is convenient for using the octagonal drainage channel to reduce the impact energy of water flow collision.

[0028] See also Figure 1-Figure 3 As shown, both ends of the drainage pipe structure composed of the outer cover pipe 2 and the inner liner pipe 4 are coaxially and detachably assembled with pipe joint assemblies 1, which are used to combine and connect adjacent drainage pipe structures through the pipe joint assembly 1. Specifically, the pipe joint assembly 1 includes a matching sleeve 102, a flange plate 101 and a clamping member 109. Both ends of the drainage pipe structure composed of the outer cover pipe 2 and the inner liner pipe 4 are sleeved with a matching sleeve 102 in a coaxial sliding manner. The outer end surface of the matching sleeve 102 is coaxially fixed with the flange plate 101, and the middle part of the matching sleeve 102 is provided with a liquid opening 106 corresponding to the pipe mouth of the inner liner pipe 4. The periphery of the matching sleeve 102 is radially extended outward to be fixed with a plurality of wing seats 103, and the outer end surface of the wing seat 103 away from the corresponding flange plate 101 is longitudinally fixed with a tightening bolt 104 through an installation sleeve 107, and the outer cover pipe 2 is coaxially fixed with a clamping member 109 at the outer peripheral position of the end near the matching sleeve 102. 9, and the periphery of the clamping member 109 is radially extended outward to be fixed with multiple connecting seats 108, and the connecting seats 108 and the wing seats 103 are respectively aligned front and back, and the tightening bolts 104 pass through the corresponding connecting seats 108 in a longitudinal sliding fit manner, and the parts passing through the connecting seats 108 are coaxially engaged with locking nuts 105, and the locking nuts 105 are pressed against the outer end faces of the corresponding connecting seats 108. The purpose of this arrangement is that the matching sleeve 102 and the flange plate 101 can be quickly combined and tightened at the end positions of the outer cover pipe 2 and the inner liner pipe 4 by installing the locking nuts 105 after the tightening bolts 104 pass through the connecting seats 108. At the same time, the matching sleeve 102 and the flange plate 101 can be axially separated from the end positions of the outer cover pipe 2 and the inner liner pipe 4 by only unscrewing the locking nuts 105. The combination and disassembly of the matching sleeve 102 and the flange plate 101 at the ends of the outer cover pipe 2 and the inner liner pipe 4 is simple and easy to achieve.

[0029] See also Figure 1-Figure 3As shown, the pipe joint assembly 1 has been optimized as follows: the liquid openings 106 are all the same size as the corresponding pipe openings of the inner liner pipe 4, so that when water is transported through the drainage pipe structure formed by the outer cover pipe 2 and the inner liner pipe 4, the water flow can be discharged stably and smoothly through the liquid openings 106. At the same time, optionally, the tensioning bolt 104 and the mounting sleeve 107 are combined and connected by threaded cooperation, so that the tensioning bolt 104 can be quickly assembled on the outside of the corresponding wing seat 103 through the mounting sleeve 107. It should be noted that, in practice, the tensioning bolt 104 and the locking nut 105 can be designed as a Tang's thread anti-loosening structure. Specifically, two locking nuts 105 with different thread rotation directions are used together to prevent loosening. Two different left and right threads also need to be processed on the tensioning bolt 104. The two threads can be on the same thread segment or not on the same thread segment. In this way, one locking nut 105 plays a tightening role and the other plays a locking role. During work, the tightening direction of the locking nut 105 located on the outside is the loosening direction of the locking nut 105 located on the inside. Tightening the outer locking nut 105 restricts the loosening of the inner locking nut 105, thereby preventing the threaded connection from loosening.

[0030] Further optionally, the hoop members 109 are each a hoop structure with bolts inserted on both sides after the upper and lower parts are embraced, so that the hoop members 109 can be firmly fixed to the outside of the outer cover tube 2 by embracing. The number of wing seats 103 and connecting seats 108 is four and they are evenly distributed in the circumferential direction. At the same time, the wing seats 103 and connecting seats 108 are staggered with the two sides of the hoop member 109. With this arrangement, when the wing seats 103 and connecting seats 108 are fixedly connected by tightening bolts 104, the two sides of the hoop member 109 will not interfere with each other. Furthermore, the inner periphery of the matching sleeve 102 is coaxially slidably matched with a sealing gasket 3, which is located between the flange plate 101 and the pipe opening of the outer cover tube 2, and the inner periphery opening of the sealing gasket 3 is the same size as the corresponding pipe opening of the inner lining tube 4. This arrangement makes it convenient to ensure and enhance the sealing effect of the contact position between the flange plate 101 and the outer cover tube 2 and the inner lining tube 4 through the setting of the sealing gasket 3, thereby preventing water leakage at this position.

[0031] With the above structure, specifically in actual use, since the inner circumference of the outer cover pipe 2 is coaxially sleeved with an inner liner pipe 4 with a cross-sectional shape of a regular octagon, the drainage pipe structure composed of the outer cover pipe 2 and the inner liner pipe 4 can have an octagonal drainage channel, which is convenient for using the inner liner pipe 4 to improve the impact resistance of the drainage pipe structure and ensure that it can adapt to high-impact intensity environments with large water flow rates. At the same time, it is convenient to use the octagonal drainage channel to reduce the impact energy of the water flow during collision, which is beneficial to further improve the impact resistance of the drainage pipe structure. Since both ends of the outer cover pipe 2 and the inner liner pipe 4 are detachably assembled and installed with the pipe joint assembly 1, the tightening bolt 104 is passed through the connecting seat 108 and the locking nut 105 is installed. The method can quickly combine the matching sleeve 102 and the flange plate 101 at the end positions of the outer cover pipe 2 and the inner liner pipe 4 and tighten them. At the same time, the matching sleeve 102 and the flange plate 101 can be axially separated from the end positions of the outer cover pipe 2 and the inner liner pipe 4 by simply unscrewing the locking nut 105. The combination and disassembly of the matching sleeve 102 and the flange plate 101 at the end of the outer cover pipe 2 and the inner liner pipe 4 is simple and easy to implement, which is convenient for combining the matching sleeve 102 and the flange plate 101 at the end positions of the outer cover pipe 2 and the inner liner pipe 4 to connect the adjacent drainage pipe structures, and at the same time, it is convenient for replacing and maintaining the sealing gasket 3 after subsequently disassembling the matching sleeve 102 and the flange plate 101 from the end positions of the outer cover pipe 2 and the inner liner pipe 4.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
