[0020] In specific implementation, when the water in the foundation pit is drained through the drainage groove, in order to prevent the drainage groove from being blocked by the continuously accumulated silt, the support rod 302 is first lifted to move the bottom plate 301 into the inside of the drainage groove body 1, and because the bottom plate 301 is connected with the rotating column 305 through the support seat 306, the movement of the bottom plate 301 drives the rotating column 305 to move together, so that the stirring rod 307 is located in the storage cavity, and the support frame 304 can be connected with the rotating column 305 in advance, at this time, the limiting plate 303 at the bottom of the support frame 304 is inserted into the drainage groove body 1, and then the rotating column 305 is assisted and supported.

[0021] Then when the water flows through the water flow channel 2, it will impact the guide seat 308 to drive it to rotate, because the guide seat 308 is connected with the rotating column 305, the rotation of the guide seat 308 drives the rotating column 305 to rotate together, and because the rotating column 305 is connected with the stirring rod 307, the rotation of the rotating column 305 drives the stirring rod 307 to rotate together, at this time, with the rotation of the stirring rod 307, it will stir up the silt, and then wash it away with the water flow, thereby preventing the silt from accumulating at the bottom of the drainage groove body 1, increasing the water flow resistance and affecting the drainage speed, and automatically discharging the silt, prolonging the interval between regular cleaning of the silt, reducing the frequency of manual cleaning, and lifting the support rod 302 to drive the bottom plate 301 to move upward, then the remaining silt in the storage cavity is taken out together, so that the water flow in the foundation pit can smoothly pass through the drainage groove, preventing the silt from accumulating and affecting the drainage speed;

[0022] In order to prevent the large-volume debris such as stones from colliding with the guide seat 308 and causing damage, the limiting seat 310 is first moved to be inserted into the fixed seat 309, and then the filter plate 312 is arranged in front of the guide seat 308, then when the water flow impacts the filter plate 312, the filter plate 312 will block the debris larger than the filter hole in the water flow, thereby preventing the large-volume debris from colliding with the subsequent equipment such as pipes and causing damage, and when the water flow impacts the filter plate 312 to make it move along the fixed rod 311, the filter plate 312 will press the spring 313 to cause it to deform, then when the drainage work is completed, the spring 313 will reset to generate elastic force, thereby causing the filter plate 312 and the limiting seat 310 to repeatedly collide, and then the debris with a volume comparable to the filter hole is shaken off from the filter plate 312, preventing it from blocking the filter plate 312 and affecting the water flow, and when the filter plate 312 is damaged and needs to be replaced, the limiting seat 310 can be simply moved upward to be separated from the fixed seat 309 to complete the replacement, finally, when the drainage groove in the foundation pit is used, it plays a role of facilitating the blocking of large-volume debris and preventing the accumulation of silt.

[0023] To sum up, the anti-sediment accumulation foundation pit drainage groove has the advantages that: the drainage groove body 1 is placed in the groove of the foundation pit first, then the water flow is guided out through mechanical drainage and pump drainage, so that the water flow flows out of the foundation pit through the water flow channel 2, thereby keeping the foundation pit dry, facilitating subsequent construction, which is the prior art and will not be described in detail here, the auxiliary mechanism 3 blocks the bulky sundries, thereby preventing the bulky sundries from colliding with the subsequent equipment such as pipes and causing damage, and the spring 313 resets the filter plate 312 and the limiting seat 310 to repeatedly collide, thereby preventing the filter plate 312 from being blocked and affecting the water flow, and when the water flow passes through the drainage groove, it will impact the guide seat 308 to make the stirring rod 307 rotate, then the stirring rod 307 will stir up the sediment and wash it away with the water flow, thereby automatically discharging the sediment and reducing the frequency of manual cleaning, thereby preventing the sediment from affecting the drainage speed, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.
