[0026] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0028] In a specific embodiment, Figure 1-8 As shown, a low-temperature resistant, pressure-bearing drainage blind ditch includes a plurality of tray seats 1, on which trays 2 are detachably fixedly mounted, on which seepage pipes 3 are fixedly mounted, and the outer sides of the seepage pipes 3 are wrapped with a permeable layer 4, a geotextile cloth 5 and a gravel filter 6 in sequence.

[0029] The two ends of the seepage pipe 3 are connected with a socket joint 71 and a socket plug 72 respectively, and the socket joint 71 and the socket plug 72 are adapted to each other. The two ends of the seepage pipe 3 are fixedly installed with end covers 8 respectively, so as to facilitate the end-to-end connection of several low-temperature resistant and pressure-bearing drainage blind ditches.

[0030] In this embodiment, a wrapping tape 7 is fixedly installed at one end of the pallet seat 1, and a pallet seat buckle hole 11 is opened at the other end. A buckle 81 is fixedly installed at the end of the wrapping tape 7 away from the connection end with the pallet seat 1, and the buckle 81 matches the pallet seat buckle hole 11. The wrapping tape 7 bypasses the outside of the gravel filter 6 and fixes the gravel filter 6 by snapping the buckle 81 into the pallet seat buckle hole 11.

[0031] like Figure 2As shown, in this embodiment, the outer wall of the seepage pipe 3 is spirally wound with a strong steel ring 31, and the strong steel ring 31 is threaded. The strong steel ring 31 is perpendicular to the outer surface of the seepage pipe 3, thereby enhancing the structural strength of the seepage pipe 3 and making the seepage pipe 3 more pressure-bearing. A plurality of drainage holes 32 are opened in the upper part of the seepage pipe 3, and the drainage holes 32 are also arranged in a threaded shape. The drainage holes 32 are cross-arranged with the strong steel ring 31, and the drainage holes 32 are distributed at equal distances.

[0032] Specifically, Figure 3 As shown, the strong steel sleeve 31 is placed outside the seepage pipe 3 during hot-melt forming, and the hot-melt material of the seepage pipe 3 wraps the strong steel sleeve 31 during forming, so that the strong steel sleeve 31 is not exposed to the outside, thereby avoiding rust, increasing the load-bearing capacity and occupying less space.

[0033] like Figure 4 As shown, in this embodiment, the two ends of the tray 2 are respectively fixedly installed with tray hooks 22, and the two tray hooks 22 are detachably connected to each other so as to connect the two trays 2 end to end. The top of the tray seat 1 is provided with a groove, and the tray seat 1 is located at the bottom between the two trays 2. The two tray hooks 22 connected to each other are located in the groove, so that the seepage pipe 3 and the tray 2 are more closely fitted, and at the same time, water leakage on the seepage pipe 3 is prevented from leaking from the joint, and the tray seat 1 is prevented from detaching from the tray 2 to cause unstable connection, etc. A waterproof seal 21 located in the groove is fixedly installed between the tray seat 1 and the tray 2. The top of the tray 2 is arc-shaped, and the front and rear sides of the tray 2 are respectively fixedly installed with bending baffles 23. After the permeable layer 4, the geotextile cloth 5, and the gravel filter 6 wrap the seepage pipe 3 and bend and deform, the front and rear sides are respectively stuck in the two bending baffles 23 to prevent the deformation from recovering.

[0034] like Figure 5 As shown, in this embodiment, the upper part of the end cover 8 is L-shaped, the lower part of the end cover 8 is vertical, and a tray seat 1 is also provided at the bottom of the end cover 8, and the lower part of the end cover 8 is located in the groove at the top of the tray seat 1. The socket joint 71 is matched with the socket plug 72, and the contact part of the socket joint 71 and the socket plug 72 is coated with adhesive and wrapped with a joint water stop 73 to ensure its sealing. After the socket joint 71 is connected to the socket plug 72, a connecting steel belt 74 is wrapped around the outer side of the overlapping part to make the connection tight and enhance the tensile and shear resistance of the joint of the seepage pipe 3.

[0035] The water-permeable layer 4 is made of low-temperature resistant polyethylene or polypropylene, and is formed by wire drawing and winding followed by cooling, so that the internal structure of the water-permeable layer 4 is hollow and has anti-freezing, water permeability and bending properties, which facilitates the flow of accumulated water into the pipeline and facilitates effective contact with the seepage pipe 3 and the gravel filter 6.

[0036] The geotextile 5 is a woven geotextile or a non-woven filament geotextile or a mixture of the two. The gravel filter 6 is a mesh hollow structure, which plays the role of isolating sand and gravel and permeable to water. Specifically, it is made of low-temperature resistant polypropylene or polyethylene and is pressed and formed in one go, so that it has certain pressure bearing and wear resistance, and prevents the backfill from damaging the surface of the blind ditch.

[0037] The tray seat 1 and the tray 2 are both integrally injection molded using SMC composite material or glass fiber reinforced composite material, which has the advantages of being resistant to aging, corrosion, cold and having a long service life, and has a better use effect.

[0038] The seepage pipe 3, the socket joint 71 and the socket plug 72 are all extruded from high molecular weight polyethylene material, which is a thermoplastic resin with high crystallinity and non-polarity, so that the pressure bearing and low temperature resistance are better.

[0039] In summary: compared with concrete blind ditch, this low-temperature resistant and pressure-bearing drainage blind ditch is lighter, more compact, has strong bearing capacity and is not easy to damage, which makes the blind ditch have good cold resistance and pressure bearing capacity. It is not only suitable for frozen soil areas, but also can be used in areas with heavy rainfall and developed groundwater, as well as deep buried areas. It has the advantages of easy and quick installation, stable quality, environmental protection and strong durability.
