[0015] As a preferred embodiment of the present invention, the construction method of the drainage structure specifically comprises the following steps: S1: Select an outer frame of corresponding size according to the size of the drainage channel; S2: According to the height of the outer frame, the bottom of the drainage channel is excavated / raised and leveled; S3: Install the outer frame in the drainage channel so that the opening of the outer frame faces the deep part of the channel, and perform filling construction between the outer side of the outer frame and the drainage channel to make the structure stable; S4: Install the stopper rod into the bracket; S5: Lower the waste collection box and the movable box into the outer frame simultaneously, so that the blocking rod is located at the opening side of the outer frame; S6: Install the top plate on the top of the outer frame and fix it.

[0016] The beneficial effects of the present invention are: 1. The present invention can utilize the leak to let in water by arranging structures such as the top plate and the movable box. The water flows into the waste collecting box through the leakage channel and then flows out from one side of the waste collecting box. During this period, the receiving box can receive part of the water flowing down. When the water in the receiving box reaches a certain weight, the magnetic attraction of the first torsion spring and the first and second magnetic blocks is overcome. The receiving box tilts and dumps the water based on the rotation of the installation shaft, thereby cutting and crushing the debris that may exist in the leakage channel, thereby achieving the purpose of dredging and avoiding the situation where the leakage channel is blocked due to long-term drainage.

[0017] 2. In the present invention, when water enters the receiving box, the magnetic attraction of the first magnetic block and the second magnetic block can store force. When the first magnetic block and the second magnetic block are separated, the magnetic attraction suddenly decreases to a small value, thereby ensuring that the receiving box has sufficient kinetic energy to move downward, thereby ensuring the crushing effect. When the water in the receiving box is dumped, the structure is reset based on the rebound force of the first torsion spring.

[0018] 3. The present invention can support the movable box based on the second spring and the magnetic attraction of the fourth magnetic block and the third magnetic block by setting structures such as the guide bevel frame and the connecting rod. When the impurities accumulated in the movable box are increasing and are not easily broken by the arc-shaped cutting knife, based on the increase in overall gravity, the magnetic attraction of the third magnetic block and the fourth magnetic block is overcome, so that the movable box moves downward, and the roller contacts the top inclined surface of the guide bevel frame. Then, under the guidance of the guide bevel frame, the first spring moves to both sides, thereby releasing the support for the support block, allowing the partition to be opened to discharge the impurities inside the movable box, further improving the anti-blocking ability.

[0019] 4. The present invention provides structures such as convex strips, movable frames and insert blocks. After a certain amount of water is accumulated in the receiving box, the convex strips can be pressed when pedestrians and vehicles pass through the top plate, prompting the insert block at the bottom of the movable frame to be inserted between the first magnetic block and the second magnetic block, thereby facilitating the separation of the two, so that the receiving box can dump the water and use the arc-shaped cutting knife to crush the impurities, thereby improving practicality.

During this period, the receiving box 20 can receive part of the water flowing down. When the water in the receiving box 20 reaches a certain weight, the magnetic attraction of the first torsion spring 32 and the first magnetic block 30 and the second magnetic block 31 is overcome. The receiving box 20 tilts and dumps the water based on the rotation of the installation shaft 33, thereby cutting and crushing the debris that may exist in the water leakage channel 29, thereby achieving the purpose of dredging and avoiding the situation where the water leakage channel 29 is blocked due to long-term drainage; When water enters the receiving box 20, the magnetic attraction of the first magnetic block 30 and the second magnetic block 31 can store force. When the first magnetic block 30 and the second magnetic block 31 are separated, the magnetic attraction suddenly decreases to a small value, ensuring that the receiving box 20 has enough kinetic energy to move downward, thereby ensuring the crushing effect. When the receiving box 20 is dumped, the structure is reset based on the rebound force of the first torsion spring 32, wherein the connecting plate 21 is an inverted L-shaped structure.

Based on the limit block 15, the connecting rod 17 can be prevented from being separated from the waste collecting box 7, so that the waste collecting box 7 can be taken out synchronously to facilitate cleaning of impurities and maintenance.
