[0033] Reference Figure 1-8 ,

[0034] Example 1:

[0035] like Figures 1-6 As shown, the high-strength drainage blind ditch proposed in this embodiment includes a blind pipe assembly, a flexible joint, flange 4, and flange 5.

[0036] The blind pipe assembly includes a pipe body 1, a permeable grid layer 2 disposed on the pipe body 1, and pressure strips 3 pressed onto the permeable grid layer 2. The pipe body 1 has permeable holes. Geotextile is disposed around the outer periphery of the permeable grid layer 2. Water seeps into the pipe body 1 through the geotextile, the permeable grid layer 2, and the permeable holes. The pipe body 1 includes an outer pipe section and a reinforcing plate section disposed inside the outer pipe section. The upper part of the outer pipe section is a downward-facing semi-circular shape, and the lower part is an upward-facing semi-rectangular shape. The reinforcing plate section has a grid-like structure, for example... Figure 8 The shown is a cross-shaped grid structure. Figure 7 The addition of polygonal grid-like structures to the cross-shaped base structure effectively improves the structural strength of pipe 1 and enhances its compressive strength.

[0037] Multiple sets of blind pipe assemblies and flexible joints are provided. Each set of blind pipe assemblies is connected to flange 4 and flange 5 at both ends, and each set of flexible joints is also connected to flange 4 and flange 5 at both ends. Connections can be made using screws. Ultimately, when connecting into a straight pipe or making additional bends using flexible joints, the desired pipe routing can be achieved through the connection of flange 4 and flange 5.

[0038] like Figure 2 and Figure 4 As shown, the flexible joint includes a flexible telescopic sleeve 7 with an undulating, zigzag outer circumference and two fixing rings 8 respectively disposed on the outer circumferential surfaces of both ends of the flexible telescopic sleeve 7. The two fixing rings 8 are respectively disposed on the inner circumferential surfaces of flange 1 4 and flange 2 5. The flexible telescopic sleeve 7 is made of rubber material and can be bent and telescopic. The fixing rings 8 adopt a rigid structure, such as stainless steel rings or hard plastic rings, which can prevent deformation of the ends of the flexible telescopic sleeve 7, thereby aligning the flexible telescopic sleeve 7 with the pipe body 1.

[0039] like Figure 4 As shown, a reinforcing ring 9 is embedded inside the flexible telescopic sleeve 7 to improve the compressive strength of the flexible telescopic sleeve 7.

[0040] Flange 4 has an inwardly extending baffle portion 41 on its inner side, which abuts against the blind pipe assembly and the end of the flexible joint. Flange 5 has an inwardly extending baffle portion 51 on its inner side, which abuts against the end of the blind pipe assembly and the flexible joint. Flange 5 is connected to flange 4 in a one-to-one correspondence.

[0041] like Figure 3 and Figure 4 As shown, both the outer sides of the first baffle part 41 and the second baffle part 51 are provided with sealing rings 6. When positioning the blind tube assembly and the end of the flexible joint, the end of the tube body 1 abuts against the sealing ring 6, and the fixing ring 8 can also abut against the sealing ring 6. Positioning and sealing connection are achieved by abutting against the sealing ring 6. Even if the end of the tube body 1 is rough and uneven, it can still be positioned and sealed by the sealing ring 6.

[0042] To improve the sealing performance of the connection between flange 4 and flange 5, flange 4 has a groove 1 on its end face, and flange 5 has a groove 2 on its end face. A sealing ring 10 is embedded in both groove 1 and groove 2. After the sealing ring 10 is installed in place, flange 4 and flange 5 are connected together using screws to achieve an effective seal.

[0043] In this embodiment, the blind pipe assembly and the flexible joint end are positioned by the baffle on the flange, which aligns the flange, blind pipe assembly, and flexible joint. Then, flange 4 and flange 5 are connected, achieving a neat installation of the entire pipeline and facilitating smooth water transport. By adding a sealing ring 6, the sealing and positioning installation of the rough-faced pipe body 1 can be further improved.

[0044] Example 2:

[0045] The high-strength drainage blind ditch proposed in this embodiment, compared to Embodiment 1, has the following advantages: Figures 3-6 As shown, flange 4 has a snap-fit ​​part 42 at the bottom, and flange 5 has a snap-fit ​​part 52 at the bottom for snap-fit ​​part 42 to snap into. The snap-fit ​​part 42 and the snap-fit ​​part 52 are snapped together, which can position the two flanges to align and improve the anti-detachment performance.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
