Detailed Implementation

[0026] The principles and features of this utility model are described below. The embodiments given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0027] It should be noted that when a part or component is considered to be "connected to," "located on," or "assembled" to another part or component, it can be directly mounted on the other part or component, or it may be located in an intermediate part or component. The terms "left," "right," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0028] In one specific implementation, such as Figures 1-8 As shown, a low-temperature resistant, pressure-bearing drainage ditch includes several tray seats 1, on which trays 2 are detachably and fixedly installed. Drainage pipes 3 are fixedly installed on the trays 2. The drainage pipes 3 are wrapped with a permeable layer 4, a geotextile fabric 5, and a gravel filter screen 6 in sequence.

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

[0030] In this embodiment, a wrapping tape 7 is fixedly installed at one end of the tray base 1, and a tray base 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 end connected to the tray base 1. The buckle 81 matches the tray base buckle hole 11. The wrapping tape 7 passes around the outside of the gravel filter 6 and the gravel filter 6 is fixed by snapping the buckle 81 into the tray base buckle hole 11.

[0031] like Figure 2As shown, in this embodiment, a strong steel collar 31 is spirally wound around the outer wall of the seepage pipe 3. The strong steel collar 31 is threaded and perpendicular to the outer surface of the seepage pipe 3, which enhances the structural strength of the seepage pipe 3 and makes the seepage pipe 3 more pressure-resistant. The upper part of the seepage pipe 3 is provided with a number of drainage holes 32. The drainage holes 32 are also arranged in a threaded manner. The drainage holes 32 are arranged in a cross pattern with the strong steel collar 31 and are evenly distributed.

[0032] Specifically, such as Figure 3 As shown, when the seepage pipe 3 is hot-melted and formed, the strong steel collar 31 is placed on the outside of the seepage pipe 3. When the hot-melt material of the seepage pipe 3 is formed, it wraps the strong steel collar 31, so that the strong steel collar 31 is not exposed to the outside, avoiding rust, increasing the load-bearing capacity, and occupying less space.

[0033] like Figure 4 As shown, in this embodiment, tray hooks 22 are fixedly installed at both ends of the tray 2, and the two tray hooks 22 are detachably connected to connect the two trays 2 end to end. The top of the tray seat 1 has a groove, and the tray seat 1 is located at the bottom between the two trays 2. The two interconnected tray hooks 22 are located in the groove, so that the drainage pipe 3 fits the tray 2 more closely, and at the same time, it prevents water leakage from the drainage pipe 3 from leaking from the joint, and also prevents the tray seat 1 from detaching from the tray 2, causing unstable connection. 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 bending baffles 23 are fixedly installed on the front and rear sides of the tray 2, respectively. After the permeable layer 4, geotextile fabric 5, and gravel filter 6 wrap the drainage pipe 3 and bend and deform, the front and rear sides are respectively inserted into the two bending baffles 23 to prevent the deformation from returning to its original state.

[0034] like Figure 5 As shown, in this embodiment, the upper half of the end cap 8 is L-shaped, and the lower half of the end cap 8 is vertical. A tray seat 1 is also provided at the bottom of the end cap 8, and the lower half of the end cap 8 is located in a groove at the top of the tray seat 1. The connector 71 is matched with the plug 72. Adhesive is applied to the contact portion of the connector 71 and the plug 72, and a joint water-stop tape 73 is wrapped around it to ensure its sealing. After the connector 71 and the plug 72 are connected, a connecting steel strip 74 is wrapped around the outer side of the overlapping portion to tighten the connection and enhance the tensile and shear resistance of the joint of the seepage pipe 3.

[0035] The permeable layer 4 is made of low-temperature resistant polyethylene or polypropylene. It is formed by drawing and winding the fibers and then cooling it to make the internal structure of the permeable layer 4 hollow. It also has antifreeze, permeability and bending performance, which facilitates the flow of water into the pipe and facilitates effective contact with the seepage pipe 3 and the gravel filter screen 6.

[0036] The geotextile fabric 5 is a woven geotextile fabric, a non-woven filament geotextile fabric, or a mixture of both. The gravel filter screen 6 has a mesh-like perforated structure, which serves to isolate sand and gravel and prevent water penetration. Specifically, it is made of low-temperature resistant polypropylene or polyethylene and is molded in one piece, giving it certain pressure resistance and wear resistance, and preventing backfill from damaging the surface of the blind drain.

[0037] Both the tray base 1 and the tray 2 are integrally injection molded from SMC composite material or glass fiber reinforced composite material. This material has the advantages of being resistant to aging, corrosion, and cold, and has a long service life, resulting in better performance.

[0038] The drainage pipe 3, the connector 71, and the plug 72 are all made of high molecular weight polyethylene by extrusion molding. This high-crystallinity, non-polar thermoplastic resin provides better pressure resistance and low-temperature resistance.

[0039] In summary, compared to concrete blind drains, this low-temperature resistant, pressure-bearing drainage blind drain is lighter, more compact, has a stronger load-bearing capacity, and is less prone to damage. This gives the blind drain excellent cold resistance and pressure resistance, making it suitable not only for frozen soil areas but also for areas with high rainfall, well-developed groundwater, and deep burial areas. It also has advantages such as convenient and quick installation, stable quality, and strong environmental durability.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Anyone skilled in the art can smoothly implement this utility model according to the accompanying drawings and the above description. However, any modifications, alterations, or equivalent changes made by those skilled in the art without departing from the scope of the technical solution of this utility model using the disclosed technical content are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or evolutions made to the above embodiments based on the essential technology of this utility model are still within the protection scope of the technical solution of this utility model.
