[0028] Example 1

[0029] like Figures 1-6 As shown, this embodiment proposes a first type of high-strength drainage blind ditch, which includes at least one blind pipe assembly, at least one flexible joint, at least two flanges 4 and at least two flanges 5.

[0030] Specifically, in this first embodiment, the blind pipe assembly includes a pipe body 1, a permeable grid layer 2 disposed on the pipe body 1, and a pressure strip 3 pressed onto the permeable grid layer 2. The pipe body 1 includes an outer pipe section and a radial support grid 11 disposed inside the outer pipe section. The upper part of the outer pipe section is a downward-opening semi-circle, and the lower part is an upward-opening semi-rectangular section. The radial support grid 11 is a grid-like structure, for example... Figure 8 The shown is a cross-shaped grid structure. Figure 7 The diagram shows a polygonal grid-like structure added to a cross-shaped base. Figure 9 The illustrated rhomboid grid structure, as well as other grid-like structures, etc., with the radial support mesh 11 covering the inner cavity of the outer pipe and dividing it into at least two interconnected flow channels, effectively improves the structural strength of the pipe body 1 and enhances its compressive strength. Furthermore, this embodiment also features permeable holes penetrating the surface of the outer pipe, and geotextile is placed around the periphery of the permeable grid layer 2. Water can then sequentially seep into the pipe body 1 through the geotextile, the permeable grid layer 2, and the permeable holes.

[0031] like Figure 2 and Figure 4 As shown, the flexible joint includes a flexible telescopic sleeve 7 with an undulating outer periphery and two fixing rings 8 respectively disposed on the outer periphery of both ends of the flexible telescopic sleeve 7. The flexible telescopic sleeve 7 is made of rubber and can be bent and telescopic. The fixing rings 8 have a rigid structure, such as stainless steel rings or hard plastic rings, thereby preventing deformation of the ends of the flexible telescopic sleeve 7 and ensuring alignment between the flexible telescopic sleeve 7 and the pipe body 1. Furthermore, as a preferred embodiment, such as... Figure 4As shown, the first embodiment can also be embedded with a reinforcing ring 9 in the flexible telescopic sleeve 7 to improve the compression resistance of the flexible telescopic sleeve 7. The flange one 4 is installed at the left end of the blind pipe assembly and the left end of the flexible joint, the flange two 5 is installed at the right end of the blind pipe assembly and the right end of the flexible joint, and when connecting multiple blind pipe assemblies and multiple flexible joints, the flange one 4 and the flange two 5 can be detachably connected together by screws, thereby connecting adjacent blind pipe assemblies and blind pipe assemblies, blind pipe assemblies and flexible joints, and forming corresponding straight pipe structures and elbow structures.

[0032] In order to ensure that the adjacent blind pipe assemblies and blind pipe assemblies, blind pipe assemblies and flexible joints are connected neatly when installing the flange one 4 and the flange two 5, the first embodiment extends the inner ring of the flange one 4 inwardly and provides a baffle part one 41, and the inner ring of the flange two 5 extends inwardly and provides a baffle part two 51, and a side of the baffle part one 41 for abutting the pipe body or the flexible joint is provided with a sealing ring 6, and a side of the baffle part two 51 for abutting the pipe body or the flexible joint is also provided with a sealing ring 6. At this time, when the flange one 4 is installed at the blind pipe assembly, the sealing ring 6 at the baffle part one 41 of the flange one 4 abuts the end of the pipe body 1; when the flange one 4 is installed at the flexible joint, the sealing ring 6 at the baffle part one 41 of the flange one 4 abuts the end of the flexible joint, and the outer ring of the fixing ring 8 abuts the inner periphery of the flange one 4; when the flange two 5 is installed at the blind pipe assembly, the sealing ring 6 at the baffle part two 51 of the flange two 5 abuts the end of the pipe body 1; when the flange two 5 is installed at the flexible joint, the sealing ring 6 at the baffle part two 51 of the flange two 5 abuts the end of the flexible joint, and the outer ring of the fixing ring 8 abuts the inner periphery of the flange two 5, thereby realizing positioning and sealing connection through the structure abutting the sealing ring 6. In this way, even if the end of the pipe body 1 is rough and uneven, it can also be positioned and sealed by the sealing ring 6.

[0033] In order to improve the sealing performance of the connection between the flange one 4 and the flange two 5, the end face of the flange one 4 has a groove one, and the end face of the flange two 5 has a groove two, and a sealing ring 10 is embedded and installed in the groove one and the groove two. After the sealing ring 10 is installed in place, the flange one 4 and the flange two 5 are connected together by screws to realize effective sealing.

[0034] Based on this, the first embodiment can pass and disperse the external force on the pipe body 1 through the special radial support grid 11, support the pipe body 1, so that it has better mechanical properties and stable drainage function; the end of the blind pipe assembly and the end of the flexible joint are positioned by the baffle part on the two flanges, so that even if the end of the blind pipe assembly or the end of the flexible joint is uneven, it can ensure that the interface of the blind pipe assembly and the blind pipe assembly, the interface of the blind pipe assembly and the flexible joint are flat through the baffle part 41 and the sealing ring 6 provided at the flange 4, the baffle part 52 and the sealing ring 6 provided at the flange 5, and the regular installation of the entire pipeline is ensured, so as to facilitate the smooth water transportation of the entire pipeline.
