The upper and lower ends of the vertical drainage pipe 4 are connected with tees 6, and the two tees 6 are connected with the horizontal drainage pipe 2. The bottom of the tee 6 at the bottom of the vertical drainage pipe 4 is connected with the curved pipe section drainage pipe 5, and a plurality of drainage holes 3 are evenly opened on the horizontal drainage pipe 2.

[0028] Specifically, in this embodiment, the diameter of the plurality of drainage holes 3 on the horizontal drainage pipe 2 is 8 mm.

[0029] Specifically, in this embodiment, the diameter of the horizontal drainage pipe 2 is 100 mm, the diameter of the vertical drainage pipe 4 is 150 mm, and the length of the horizontal drainage pipe 2 is 1 m.

[0030] Specifically, in this embodiment, the spacing between the plurality of drainage holes 3 on the horizontal drainage pipe 2 is 50m.

[0031] Specifically, in this embodiment, the four sides of the horizontal drainage pipe 2 are wrapped with two layers of non-woven fabrics with gravel of 30 mm in diameter.

[0032] By providing 30 mm gravel wrapped in non-woven fabric, the soil around the horizontal drainage pipe 2 can be filtered, so that the moisture in the soil can enter the horizontal drainage pipe 2 through filtration, preventing debris particles in the soil from entering the drainage hole 3 and causing blockage.

[0033] Specifically, in this embodiment, the horizontal drainage pipe 2, the vertical drainage pipe 4, the curved section drainage pipe 5 and the three-way pipe 6 in the drainage structure 1 are all made of PVC.

[0034] Specifically, in the present embodiment, a docking groove 8 is provided at the open end of each of the three-way pipes 6 , and the diameter of the docking groove 8 is the same as the outer diameter of the vertical drain pipe 4 and the horizontal drain pipe 2 .

[0035] Specifically, in this embodiment, three L-shaped docking grooves 9 are evenly opened in the docking groove 8 along the circumferential direction, and three L-shaped docking blocks 7 are evenly arranged along the circumferential direction on the docking surface between the vertical drain pipe 4 or the horizontal drain pipe 2 and the docking groove 8.

[0036] Through the mutual cooperation between the L-shaped docking groove 9 and the L-shaped docking block 7, when the vertical drain pipe 4 or the horizontal drain pipe 2 is docked with the three-way pipe 6, the L-shaped docking block 7 on the vertical drain pipe 4 or the horizontal drain pipe 2 can be inserted into the L-shaped docking block 7 on the docking groove 8 and rotated a certain angle in the clockwise direction, so as to realize the connection and locking between the L-shaped docking block 7 and the L-shaped docking groove 9, thereby achieving the purpose of convenient docking, and glue can be applied in the docking groove 8 before connection to ensure subsequent waterproofness and connection stability.

[0037] Specifically, in the present embodiment, a reset groove 11 is provided on the inner wall at the bottom of the L-shaped docking groove 9, a movable top block 13 is slidably arranged in the reset groove 11, a reset spring 12 is arranged in the reset groove 11, one end of the reset spring 12 is mounted on the inner wall of the reset groove 11, and the other end of the reset spring 12 is mounted on the movable top block 13, a limiting hole 10 adapted to the movable top block 13 is provided at the bottom of the L-shaped docking block 7, the top end of the movable top block 13 is spherical, and the bottom diameter of the movable top block 13 is larger than the opening end diameter of the reset groove 11.

[0038] By arranging structures such as the movable top block 13, the return spring 12 and the limiting hole 10, when the L-shaped docking block 7 and the L-shaped docking groove 9 are connected and locked, the movable top block 13 can be squeezed by the L-shaped docking block 7 and the movable top block 13 can be retracted into the return slide groove 11. When the L-shaped docking block 7 and the L-shaped docking groove 9 are docked, the movable top block 13 will be aligned with the limiting hole 10. At this time, the elastic potential energy of the return spring 12 can push the movable top block 13 to be inserted into the limiting hole 10 at the bottom of the L-shaped docking block 7, thereby further improving the connection stability between the vertical drain pipe 4 or the horizontal drain pipe 2 and the three-way pipe 6.
