[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] like Figure 1-4As shown, a weldable landscape drainage structure includes a U-shaped drain pipe 1 and a cover plate 8. The U-shaped drain pipe 1 is provided with welding parts at both ends, and the shape of the welding parts corresponds to the U-shaped drain pipe 1. After multiple U-shaped drain pipes 1 are connected in series, the two welding parts abutting each other can be connected by welding, so that the overall structure after the series connection is stable, the sealing is strong, and it is not easy to seep water; the U-shaped drain pipe 1 is provided with mounting plates 2 on both sides for mounting on the excavated trench, and the upper end of the mounting plate 2 is provided with a limiting plate 3, and the cover plate 8 is installed on the upper end of the mounting plate 2, and the cover plate 8 is just embedded between the limiting plates 3. The cover plate 8 is provided with a drainage groove 9, and the water flows through the drainage groove 9 to converge into the U-shaped drain pipe 1.

[0020] In the above embodiment, the welding part includes a first welding part 4 and a second welding part 5. The first welding part 4 and the second welding part 5 are respectively located at the two ends of the U-shaped drain pipe 1, and the lower edge of the first welding part 4 and the upper edge of the second welding part 5 overlap in the cross section of the U-shaped drain pipe 1. When multiple U-shaped drain pipes 1 are connected in series, the first welding part 4 and the second welding part 5 on the adjacent U-shaped drain pipes 1 are laterally abutted and overlapped up and down, and the structure is stable, which is convenient for welding. A positioning plate 11 is provided at one end of the cover plate 8. The positioning plate 11 is equal in width to the first welding part 4. After multiple U-shaped drain pipes 1 are connected in series, the positioning plate 11 can seal the upper end area of ​​the first welding part 4 to prevent debris from entering the U-shaped drain pipe 1; the first welding part 4 and the second welding part 5 have the same overlapping width, and the gap is extremely small when overlapping, which is conducive to forming a firm weld without the need for welding filler. The first welding part 4 is provided with a through hole 6, and the second welding part 5 is provided with a positioning hole 7. When the first welding part 4 is overlapped with the upper end of the second welding part 5, a cylindrical metal rod can be inserted into the through hole 6 and the positioning hole 7 at the same time to position multiple U-shaped drainage pipes 1, and the cylindrical metal rod can be pulled out after welding to ensure the smooth progress of the welding process.

[0021] In the above embodiment, the lower end of the U-shaped drain pipe 1 is provided with a sheet structure 13. When the U-shaped drain pipe 1 is sunk into the groove, the sheet structure 13 is inserted into the soil layer to prevent the U-shaped drain pipe 1 from lateral displacement, which is conducive to the subsequent welding work. The middle part of the cover plate 8 is provided with a groove 10, and the drainage groove 9 is located in the groove 10. The cover plate 8 can be installed on the front and back sides; when the groove 10 is downward, the upper end surface of the cover plate 8 is flush with the upper end surface of the limit plate 3, which is suitable for scenes where pedestrians or vehicles can pass; when the groove 10 is upward, the groove 10 can be filled with pebbles and other landscape items with a particle size larger than the drainage groove 9, which is suitable for scenes where people pass and need decoration and beautification. The drainage groove 9 is grid-shaped, and the structure is evenly stressed and durable. The upper end of the cover plate 8 is also provided with an anti-slip strip 12 to provide protection for the passage of people and avoid slipping.

[0022] Description of the working method of this utility model:

[0023] As with the requirements for laying traditional drainage ditches, before laying the U-shaped drainage pipe 1 of the present technical solution, it is necessary to excavate the road and compact the soil layer in the trench; the U-shaped drainage pipe 1 is hoisted into the trench, and multiple U-shaped drainage pipes 1 are connected in series, and the first welding parts 4 and the second welding parts 5 of adjacent U-shaped drainage pipes 1 are laterally abutted and overlapped up and down, and then a cylindrical metal rod is inserted into the through hole 6 and the positioning hole 7 at the same time, and the adjacent U-shaped drainage pipes 1 are positioned and accurately found, and then welding can be performed; since the gap between adjacent U-shaped drainage pipes 1 is extremely small, welding does not require the aid of welding rods, and the first welding parts 4 and the second welding parts 5 of adjacent U-shaped drainage pipes 1 can be directly welded; multiple welded U-shaped drainage grooves 9 form a stable structure, which can withstand a certain degree of pressure or vibration caused by pedestrians and vehicles. At the same time, the welding covers all the joints of adjacent U-shaped drainage pipes 1, and the sealing is good, which avoids problems such as foundation settlement caused by water seepage in the drainage structure. After multiple U-shaped drainage pipes 1 are laid, take out the cylindrical metal rod and cover the cover plate 8 on the upper end of the mounting plate 2. At this time, the positioning plate 11 and the cover plate 8 together completely seal the opening above the U-shaped drainage trough 9, and only the drainage trough 9 can be connected; if it is necessary to modify or hide the drainage structure, the cover plate 8 can be turned over to the upward side of the groove 10, and the groove 10 can be filled with pebbles and other landscape items with a particle size larger than the drainage trough 9, which not only beautifies and shields, but also does not affect the normal realization of the drainage function.

[0024] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
