Description

Technical Field

[0001] This application relates to the field of double-wall corrugated pipe technology, and more particularly to an impact-resistant structure for a PE double-wall corrugated pipe. Background Technology

[0002] Double-wall corrugated pipes are a type of pipe with an annular outer wall and a smooth inner wall. The outer wall is corrugated and used in urban rainwater and sewage collection and discharge systems. However, existing corrugated pipes rely solely on their material properties when facing impacts, resulting in a lack of impact resistance. During transportation, double-wall corrugated pipes are easily damaged by collisions. During the use of the pipes, they may be subjected to unexpected external impacts. Once the pipe is damaged by an impact, its structural integrity is compromised, which may lead to local deformation of the pipe, thereby affecting the drainage capacity of the pipe and posing certain safety hazards.

[0005] This application provides an impact-resistant structure for a PE double-wall corrugated pipe, including a pipe body, a plurality of first corrugated portions spaced apart along the length of the pipe body, and a protective component movably mounted on the pipe body. The protective component includes a protective sleeve, and the protective sleeve is provided with a slot penetrating the protective sleeve. The slot is provided with a plurality of slots spaced apart along the length of the protective sleeve.

[0006] When the protective sleeve is installed on the pipe body, part of the first corrugated part passes through the slot. The outer periphery of the protective sleeve is also provided with a second corrugated part. Several second corrugated parts are provided and distributed at intervals along the length direction of the protective sleeve. The slot is located between the two sets of second corrugated parts.

[0007] When the protective sleeve is installed on the pipe body, the second corrugated part and the first corrugated part are distributed alternately at different heights;

[0008] The protective sleeve is provided in two sets and symmetrically distributed on both sides of the tube body, and the two sets of protective sleeves form a receiving area to accommodate the tube body;

[0009] A reinforcing rib is provided between two adjacent sets of second corrugated sections. Several reinforcing ribs are provided and distributed at intervals along the circumference of the protective sleeve. The reinforcing ribs are located above the first corrugated section.

[0010] In one embodiment, the tube body has an inlet end and an outlet end at both ends, and the tube body has an interface at the outlet end, the diameter of which is larger than the diameter of the tube body.

[0011] The interface section has a through groove that penetrates the interface section. Several through grooves are provided and are spaced apart along the circumference of the tube body. A snap-fit ​​component is movably provided on the through groove.

[0012] The tube body is provided with an installation groove at the inlet end, and several installation grooves are provided and distributed at intervals along the circumference of the tube body;

[0013] When the two sets of pipes are connected to each other, the discharge end is embedded into the inlet end, so that the through groove and the installation groove are connected. By moving the snap-fit ​​part, part of the snap-fit ​​part is embedded into the installation groove.

[0014] In one embodiment, a buffer air cushion is provided on the reinforcing rib, and the buffer air cushion is located between the two sets of second corrugated sections.

[0015] In one embodiment, the protective component further includes a screw member, and extension plates are provided on both sides of the protective component, with bolt holes on the extension plates;

[0016] When the two sets of protective sleeves are located on both sides of the pipe body, the two sets of bolt holes are interconnected, the screw is threaded into the two sets of bolt holes and a nut is installed.

[0023] The advantages or beneficial effects of the above technical solutions include at least the following:

[0024] This application discloses an impact-resistant structure for a PE double-wall corrugated pipe. Two sets of protective sleeves are installed on the pipe body. Since the first corrugated section on the pipe body passes through the slots in the protective sleeves and is interleaved with the second corrugated section on the sleeves, when impacted, the impact is first applied to the second corrugated section and buffered by it. Subsequently, the impact is further buffered by the first corrugated section. Thus, the impact is reflected and dispersed between corrugations of different heights during transmission, enhancing the overall impact resistance of the pipe body. Furthermore, reinforcing ribs are provided between the two sets of second corrugated sections to prevent excessive deformation or collapse of the second corrugated sections and to absorb impact forces, further improving the overall protective capability of the pipe body. This solves the problem that existing pipe bodies lack impact resistance, leading to easy breakage during use. Attached Figure Description

[0040] Reference Figures 1-6 An impact-resistant structure for a PE double-wall corrugated pipe includes a pipe body 1, which has several first corrugated portions 11 spaced apart along the length of the pipe body 1. A protective component 2 is movably installed on the pipe body 1. The protective component 2 includes a protective sleeve 21. The protective sleeve 21 has a slot 211 penetrating through the protective sleeve 21. Several slots 211 are provided and spaced apart along the length of the protective sleeve 21.

[0041] When the protective sleeve 21 is installed on the pipe body 1, part of the first corrugated part 11 passes through the slot 211. The outer periphery of the protective sleeve 21 is also provided with a second corrugated part 22. Several second corrugated parts 22 are provided and are distributed at intervals along the length direction of the protective sleeve 21. The slot 211 is located between two sets of second corrugated parts 22.

[0042] When the protective sleeve 21 is installed on the pipe body 1, the second corrugated part 22 and the first corrugated part 11 are arranged in an alternating high and low distribution. When subjected to external impact, it will first contact the second corrugated part 22.

[0043] Two sets of protective sleeves 21 are provided and symmetrically distributed on both sides of the tube body 1. The two sets of protective sleeves 21 form an accommodating area for the tube body 1, and the two sets of protective sleeves 21 can fit tightly against the outer periphery of the tube body 1.

[0044] A reinforcing rib 23 is provided between two adjacent sets of second corrugated sections 22. Several reinforcing ribs 23 are provided and are distributed at intervals along the circumferential direction of the protective sleeve 21. The reinforcing ribs 23 are located above the first corrugated section 11.

[0045] Based on the above structure, two sets of protective sleeves 21 are respectively installed on the outer periphery of the tube body 1. This wrap-around protective structure can protect the tube body 1 from both sides. Regardless of whether the impact comes from the left or right side of the tube body 1, or from an oblique impact from other directions, the protective sleeves 21 can effectively play a protective role. The first corrugated part 11 provided on the tube body 1 passes through the slot 211 provided on the protective sleeve 21 and is located between the two sets of second corrugated parts 22. When the tube body 1 is subjected to external impact, the first corrugated part 11 and the second corrugated part 22, which are distributed at different heights, can work together. The second corrugated part 22 distributes the impact from the outside. Furthermore, the first corrugated part 11, as a structural part of the tube body 1 itself, has a certain degree of elasticity and deformation capacity, which can further buffer part of the impact energy, so that the impact is transmitted more effectively. During the process, reflection and dispersion occur between corrugations at different heights, enhancing the overall impact resistance of the pipe body 1. Furthermore, the reinforcing ribs 23 set between two adjacent sets of second corrugated sections 22 can enhance the structural stability of the protective sleeve 21 itself. When the protective sleeve 21 is impacted, the reinforcing ribs 23 can prevent the second corrugated sections 22 from excessively deforming or collapsing. Through the cooperation of the protective components 2, the pipe body 1 can be protected. Moreover, the two sets of protective sleeves 21 in the protective components 2 adopt a separate structure, which can be replaced after long-term use, and can also be maintained when a single protective sleeve 21 is damaged. Through the cooperation of the protective components 2, the overall protective capability of the pipe body 1 is improved, solving the problem that the existing pipe body 1 itself does not have an impact resistance effect, and the pipe body 1 breaks during use, affecting its use.

[0046] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 6 The tube body 1 has an inlet end and an outlet end at both ends. The tube body 1 has an interface 12 at the outlet end. The diameter of the interface 12 is larger than the diameter of the tube body 1. The size of the interface 12 is set to accommodate the tube body 1.

[0047] The interface section 12 has a through groove 121 that penetrates the interface section 12. Several through grooves 121 are provided and are spaced apart along the circumferential direction of the tube body 1. A snap-fit ​​member 122 is movably provided on the through groove 121.

[0048] The pipe body 1 has an installation groove 13 at the inlet end. Several installation grooves 13 are provided and distributed at intervals along the circumference of the pipe body 1. When two sets of pipe bodies 1 are connected, the outlet end is inserted into the inlet end, so that the through groove 121 and the installation groove 13 are connected. By moving the snap fastener 122, part of the snap fastener 122 is inserted into the installation groove 13. When two sets of pipe bodies 1 are connected, it is only necessary to insert the outlet end of one pipe body 1 into the inlet end of the other pipe body 1 to align and connect the through groove 121 and the installation groove 13. Then, the snap fastener 122 is moved to partially insert into the installation groove 13 to complete the connection. This operation is simple and direct, without complicated tools and steps, which can significantly improve the installation efficiency, especially in large-scale pipeline laying projects. After the snap fastener 122 is inserted into the installation groove 13, multiple fixing points are formed in the circumference of the pipe body 1, which can effectively prevent the pipe body 1 from undergoing relative displacement in the axial and radial directions, and enhance the stability of the connection.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 A buffer air cushion 231 is provided on the reinforcing rib 23. The buffer air cushion 231 is located between the two sets of second corrugated parts 22. The buffer air cushion 231 can play a buffering role when the protective sleeve 21 is subjected to external collision, further reducing the impact force on the tube body 1.

[0050] In one embodiment, reference is made to Figures 1-3 The protective component 2 also includes a screw 24. Extension plates 212 are provided on both sides of the protective component 21. The extension plates 212 have bolt holes 2121. When the two sets of protective components 21 are located on both sides of the pipe body 1, the two sets of bolt holes 2121 are connected to each other. The screw 24 is threaded to the two sets of bolt holes 2121 and is equipped with a nut. When the two sets of bolt holes 2121 are connected and threaded through the screw 24, the two sets of protective components 21 can fit tightly together, thereby protecting the pipe body 1.

[0051] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The second corrugated section 22 has inclined ends 221 on both sides, so that the second corrugated section 22 has a trapezoidal cross section. The reinforcing ribs 23 are installed on the inclined ends 221. The second corrugated section 22 with the trapezoidal structure formed by the inclined ends 221 replaces the traditional arc transition, so that the stress is evenly diffused along the inclined surface, avoiding stress concentration at a single position of the crest or trough. The reinforcing ribs 23 are installed along the inclined ends 221 to form a support structure similar to a triangular truss. The impact force is decomposed into axial and radial components through the inclined ends 221. The reinforcing ribs 23 can absorb the radial component and convert it into circumferential stress.

[0052] In one embodiment, reference is made to Figure 2 , Figure 5 and Figure 7 The inner ring of the interface part 12 is provided with a groove 123, and a sealing gasket 1231 is sleeved inside the groove 123. The sealing gasket 1231 is made of a stretchable rubber material. When the discharge end is inserted into the inlet end, the sealing gasket 1231 abuts against the outer circumference of the tube body 1. The setting of the sealing gasket 1231 can seal the connection between the two sets of tube bodies 1 when they are connected, thereby improving the sealing performance during connection.

[0053] In one embodiment, reference is made to Figure 1 and Figure 3 The extension plate 212 is provided with magnetic blocks 2122 and limiting grooves 2123 on both sides. The limiting grooves 2123 have magnetic layers 21231. When the two sets of extension plates 212 are attached, the magnetic blocks 2122 are embedded in the limiting grooves 2123 and magnetically attracted to the magnetic layers 21231. The magnetic blocks 2122 and the magnetic layers 21231 are two sets of mutually attracted magnetic poles, so that the two sets of protective sleeves 21 are magnetically connected. Through the cooperation of the magnetic blocks 2122 and the limiting grooves 2123, the two sets of protective sleeves 21 can play a positioning role when they are connected to each other. Furthermore, through the magnetic connection of the magnetic blocks 2122 and the magnetic layers 21231, the stability of the two sets of protective sleeves 21 when connected can be further improved.

[0054] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5The snap-fit ​​component 122 has a limiting pad 1221. The size and area of ​​the limiting pad 1221 are larger than the size and area of ​​the through groove 121. As the snap-fit ​​component 122 moves along the through groove 121, the limiting pad 1221 moves closer to or further away from the outer peripheral end face of the tube body 1. The setting of the limiting pad 1221 makes it easier for the operator to hold the snap-fit ​​component 122, and the limiting pad 1221 can limit the range of movement of the snap-fit ​​component 122. Since the through groove 121 is hollow, the setting of the limiting pad 1221 can prevent the snap-fit ​​component 122 from directly passing through the through groove 121 during use and falling off, thus blocking the snap-fit ​​component 122. When the snap-fit ​​component 122 is embedded in the mounting groove 13, the limiting pad 1221 abuts against the outer periphery of the interface part 12.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
