Description

Technical Field

[0001] This invention relates to the field of slope protection structure technology, and in particular to a slope protection system with built-in drainage pipe trench and its construction method. Background Technology

[0002] Slope protection is a measure taken to prevent riverbank erosion, protect riverbanks, and improve their stability and safety. It also beautifies the riverbank. Water accumulating on the road above the riverbank typically flows directly into the river through the slope protection. As the water flows over the slope, it easily causes soil erosion, compromising the slope's stability and integrity. Furthermore, the water carrying sediment into the river can cause siltation.

[0003] Existing patent 202122491986.5 discloses an ecological slope protection system with soil and water conservation and rainwater resource utilization functions. The system features a terraced slope protection structure on the side of the embankment near the drainage ditch. Slope protection components are laid on the terraced slope protection, and a drainage channel is located at the top of the embankment corresponding to the location of the slope protection components. Rainwater filtration components are embedded in the drainage channel, and terraced diversion pipes are also laid on the slope protection components at the location corresponding to the drainage channel. In this patent, the designed terraced diversion pipes, irrigation components, and one-way valves achieve rainwater diversion, thus reducing the scouring intensity of rainwater on the terraced slope protection to a certain extent. When the water volume in the drainage channel is large, the water pressure in the terraced diversion pipes further increases. Under the pressure of the water, the one-way valve will open automatically, serving to release the water and prevent a large amount of accumulated water on the embankment from directly scouring the terraced slope protection. Although the aforementioned patent includes a drainage channel, its placement on the outer surface of the slope protection detracts from the aesthetics of the slope and makes the drainage channel susceptible to damage, thus affecting its lifespan. Furthermore, the direct installation of the drainage channel on the slope results in poor stability. Summary of the Invention

A guide bar is provided on the inner side of the fixing cone 26 to guide and limit the up-and-down sliding of the sliding sleeve 34. The sliding sleeve 34 is threadedly connected to the screw 32, and the rotation of the screw 32 causes the sliding sleeve 34 to slide up and down inside the fixed cone 26. Several mounting plates 35 are provided on the outside of the sliding sleeve 34, and the mounting plates 35 are hinged to the sliding sleeve 34 via connecting rods 36.

Rotate the screw 32 through the limiting plate 33. The screw 32 drives the sliding sleeve 34 to descend within the fixing cone 26 through thread engagement. The sliding sleeve 34 drives the mounting plate 35 to move outward through the connecting rod 36. The mounting plate 35 drives the pin 37 to slide outward. The pin 37 passes through the limiting groove 38 and inserts into the slope body, fixing the first fixing plate 16 and the second fixing plate 17 in the pipe groove. Insert one end of the bent pipe 15 outside the water outlet pipe 8. The bent pipe 15 is placed above the fixing clamp 20 and the first sliding seat 23.

[0038] S3. Insert the second connecting pipe 9 into the other end of the bend 15. Adjust the position of the first sliding seat 23 according to the joint position of the second connecting pipe 9 and the bend 15. Tighten the set screw to lock the second sliding seat 28 onto the second fixed plate 17. The first retaining ring 22 abuts against one end of the bend 15, and the second retaining ring 25 abuts against the other end of the bend 15. Secure the first clamping plate 21 to the fixed clamping seat 20 with bolts, and secure the second clamping plate 24 to the first sliding seat 23 with bolts, thus realizing the connection between the bend 15 and the outlet pipe 8 and the second connecting pipe 9.

[0039] S4. Place the second connector 11 into the pipe groove. The third fixing plate 27 is inserted into the pipe groove through the fixing cone 26. Rotate the screw 32 through the limiting plate 33. The screw 32 drives the sliding sleeve 34 to descend within the fixing cone 26 through threaded engagement. The sliding sleeve 34 drives the mounting plate 35 to move outward through the connecting rod 36. The mounting plate 35 drives the pin 37 to slide outward. The pin 37 passes through the limiting groove 38 and inserts into the slope body, fixing the third fixing plate 27 in the pipe groove. Insert the sleeve 31 into one end of the second connecting pipe 9, and insert another second connecting pipe 9 into one end of the sleeve 19. One end of the sleeve 31 abuts against the third retaining ring 30 of a second sliding seat 28. Slide the other second sliding seat 28, and the other third retaining ring 30 abuts against the other end of the sleeve 19. Fix the third clamping plate 29 to the second sliding seat 28 with bolts, locking the second connecting pipe 9 and the sleeve 31 together.
