[0002] Plastic drainage boards (also known as plastic drainage strips or plastic sandwich panels) are a key material widely used in civil engineering and building waterproofing and drainage systems. Their core function is to achieve efficient drainage, seepage prevention, and protection through structural design.

[0003] In the existing technology, plastic drainage boards consist of a board body and protrusions. When in use, a drainage strip is fitted onto the plastic drainage board. The inner wall of the drainage strip forms several irregularly shaped channels with the board body and protrusions. During use, the drainage strip is driven into the soft soil foundation by a board inserter. Under the action of the upper preload, the pore water in the soft soil foundation is drained from the plastic drainage board into the sand layer or horizontal plastic drainage pipe laid on top, and then discharged from other places, thus accelerating the consolidation of the soft foundation.

[0004] However, existing plastic drainage boards lack reinforcement and corrosion protection structures. During transportation, the protrusions are easily damaged by external forces, and they are also easily corroded if exposed to rain during transportation. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a corrosion-resistant plastic drainage board with a reinforced structure, comprising: a plastic drainage board 1, an upper protective plate 3 and a lower protective plate 4. Several sets of protrusions 2 are fixed on the surface of the plastic drainage board 1. Several sets of protrusion protective sleeves 5 are fixed on the surface of the upper protective plate 3. Several sets of protrusion support blocks 6 are fixed on the surface of the lower protective plate 4. A reinforcing rib 7 is fixed between the upper protective plate 3 and the protrusion protective sleeves 5. Several sets of protrusions 2 are movably inserted into several sets of protrusion protective sleeves 5, and several sets of protrusion support blocks 6 are movably inserted into several sets of protrusions 2.

[0021] In actual use, the upper protective plate 3 and the lower protective plate 4 are respectively set at the upper and lower ends of the plastic drainage board 1. The protrusion support block 6 is inserted into the protrusion 2 to support the protrusion 2. The protrusion 2 is inserted into the protrusion protective sleeve 5, which protects the protrusion 2 and prevents it from being damaged by external forces. A reinforcing rib 7 is fixed between the upper protective plate 3 and the protrusion protective sleeve 5, which supports and reinforces the protrusion protective sleeve 5. The upper protective plate 3, the lower protective plate 4, and the protrusion protective sleeve 5 completely cover the plastic drainage board 1 and the protrusion 2, which can prevent the plastic drainage board 1 and the protrusion 2 from being rained on and play a role in corrosion prevention.

[0022] Example 2: Based on Example 1, in order to achieve the assembly of the upper protective plate 3 and the lower protective plate 4, the surface of the upper protective plate 3 has a plug hole 8, and the surface of the lower protective plate 4 is fixed with a plug seat 9. The plug seat 9 is movably inserted into the plug hole 8. The surface of the plug seat 9 has a locking groove 10. One end of the locking block 11 is movably inserted into the locking groove 10, and the other end of the locking block 11 extends out of the locking groove 10. The bottom surface of the end of the locking block 11 extending out of the locking groove 10 abuts against the surface of the upper protective plate 3. A spring 12 is fixed to the end of the locking block 11 that extends into the locking groove 10. The other end of the spring 12 is fixed to the inner wall of the locking groove 10. An operation window 13 is opened on the surface of the plug seat 9. An operation rod 14 is slidably connected in the operation window 13. One end of the operation rod 14 is fixed to the surface of the locking block 11, and the other end of the operation rod 14 extends out from the operation window 13.

[0023] Move the operating lever 14, which will cause the locking block 11 to move and retract completely into the locking block groove 10. At this time, the spring 12 is compressed, causing the connector 9 to be inserted into the connector hole 8. After the locking block groove 10 protrudes from the other end of the connector hole 8, release the operating lever 14. The spring 12 will push one end of the locking block 11 out of the locking block groove 10, so that the bottom surface of the locking block 11 abuts against the top of the upper protective plate 3, thereby limiting the connector 9 in the connector hole 8, thus completing the splicing of the upper protective plate 3 and the lower protective plate 4.

[0024] Example 3: Based on Example 2, in order to prevent rainwater from entering the locking slot 10 from the operating window 13 and causing corrosion to the spring 12, a baffle slot 15 is provided on the inner wall of the operating window 13. One end of the baffle 16 is movably inserted into the baffle slot 15, and the other end of the baffle 16 is fixed to the operating rod 14.

[0025] A baffle groove 15 is provided on the inner wall of the operating window 13. A baffle 16 is movably inserted into the baffle groove 15. The other end of the baffle 16 is fixed to the surface of the operating rod 14 to seal the operating window 13, thereby preventing rainwater from entering the locking groove 10 from the operating window 13 and causing corrosion to the spring 12. When the operating rod 14 is moved, the baffle 16 can retract further into the baffle groove 15 to prevent it from affecting the movement of the operating rod 14.

[0026] In actual use, the upper protective plate 3 and the lower protective plate 4 are respectively set at the upper and lower ends of the plastic drainage plate 1. The protrusion support block 6 is inserted into the protrusion 2 to support the protrusion 2. The protrusion 2 is inserted into the protrusion protective sleeve 5, which protects the protrusion 2 and prevents it from being damaged by external force. A reinforcing rib 7 is fixed between the upper protective plate 3 and the protrusion protective sleeve 5, which supports and reinforces the protrusion protective sleeve 5. The upper protective plate 3, the lower protective plate 4, and the protrusion protective sleeve 5 completely cover the plastic drainage plate 1 and the protrusion 2, which can prevent the plastic drainage plate 1 and the protrusion 2 from being rained on and play a role in corrosion prevention. When the operating lever 14 is moved, the operating lever 14 drives the locking block 11 to move, so that the locking block 11 is fully retracted into the locking block groove 10. At this time, the spring 12 is compressed. The operating lever 14 is released, and the spring 12 pushes one end of the locking block 11 out of the locking block groove 10, so that the bottom surface of the locking block 11 abuts against the top of the upper protective plate 3, thereby limiting the plug-in seat 9 in the plug-in hole 8, thus completing the splicing of the upper protective plate 3 and the lower protective plate 4. A baffle groove 15 is opened on the inner wall of the operating window 13, and a baffle 16 is movably inserted in the baffle groove 15. The other end of the baffle 16 is fixed to the surface of the operating lever 14 to seal the operating window 13, thereby preventing rainwater from entering the locking block groove 10 from the operating window 13 and corroding the spring 12. When the operating lever 14 is moved, the baffle 16 can retract further into the baffle groove 15 to prevent it from affecting the movement of the operating lever 14.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
