AI Technical Summary
HDPE double-wall corrugated pipes are prone to loosening during connection due to thermal expansion and contraction, which can lead to damage to the connection points.
The system employs a corrugated buffer sleeve and a fastening clamp structure. The corrugated buffer sleeve adapts to the thermal expansion and contraction of the pipeline, while the fastening clamp secures the double-walled corrugated pipe with bolts, ensuring a stable connection.
It effectively prevents the connection of the double-walled corrugated pipe from loosening due to thermal expansion and contraction, and maintains the sealing and stability of the connection.

[0013] The utility model will be further described in detail in combination with the drawings and specific implementation:
[0014] As Figs. 1-2 Shown, a double-wall corrugated pipe socket connecting assembly, including connecting assembly body 1, the connecting assembly body 1 includes corrugated buffer sleeve 101 and is arranged in two ends of corrugated buffer sleeve 101 two connecting sleeves 102, wherein the connecting sleeve 102 on both sides is communicated with corrugated buffer cylinder 102 respectively, and the left and right ends of connecting assembly body 1 are provided with double-wall corrugated pipe 2.
[0015] In this embodiment, the connecting sleeve 102 side is fixed with fastening panel 3, and the double-wall corrugated pipe 2 is provided with two half-ring fastening clamps 4 close to the port part, the double-wall corrugated pipe 2 is arranged between the fastening clamps 4, and the fastening clamps 4 are fixedly connected by bolts, the double-wall corrugated pipe 2 is clamped and fixed by using the fastening clamps 4, one installation panel 401 is arranged on each fastening clamp 4, two fastening pull rods 5 are arranged on the installation panel 401, and the end of the fastening pull rod 5 passes through the fastening panel 3 and is fixed by a nut.
[0016] In this embodiment, the corrugated buffer cylinder 101 is sleeved with a protection sleeve 6, and the protection sleeve 6 is used to protect the corrugated buffer cylinder 101.
[0017] In the embodiment, the double-wall corrugated pipe 2 port is expanded by hot melt flaring, facilitating the insertion of the connecting sleeve 102 into the double-wall corrugated pipe 2 port.
[0018] In use, the two connecting sleeves 102 of the connecting assembly body 1 are connected with the ports of two adjacent double-wall corrugated pipes 2, respectively, when the double-wall corrugated pipe 2 expands or shrinks due to the change of external temperature, the corrugated buffer cylinder 101 buffers and adjusts, when the double-wall corrugated pipe 2 expands due to heat, the ports of the adjacent double-wall corrugated pipes 2 are close to each other and press the corrugated buffer cylinder 101, when the double-wall corrugated pipe 2 shrinks due to cold, the distance between the ports of the adjacent double-wall corrugated pipes 2 increases and the corrugated buffer cylinder 101 is stretched, that is, the corrugated buffer cylinder 101 is stretched to adapt to the expansion and shrinkage of the double-wall corrugated pipe 2.
[0019] Moreover, after the double-wall corrugated pipe 2 is connected with the connecting sleeve 102, the fastening panel 3 and the fastening clamp 4 are connected into one by the fastening pull rod 5, the double-wall corrugated pipe 2 port is stretched to the side of the fastening panel 3 by the fastening clamp 4, the position of the double-wall corrugated pipe 2 is limited, and the connection part of the double-wall corrugated pipe 2 and the connecting sleeve 102 is prevented from loosening when shrinking.
