The hydraulic self-lifting flood control walls provided by the above embodiment are installed and fixed on water retaining structures such as dams and dams of flood control river channels, and each group of hydraulic self-lifting flood control walls are mutually matched and connected through the limiting structures 5 and the sliding groove structures 6. When the flood water level rises and sinks over the base layer 1, the lateral water pressure can provide a lateral component force for pushing the lifting bottom layer 2 to slide upwards along the inclined plane along with the continuous rising of the flood, so that the lifting bottom layer 2 can rise along with the increase of the flood water level, when the flood water level exceeds the water inlet grille 4 of the lifting bottom layer 2, the flood enters the lifting bottom layer 2 and pours into the supporting column I9 and the supporting column II 10 through the water inlet filter screen 22, the supporting column II 10 overcomes the elastic force of the spring 16 to displace downwards relative to the supporting column I9 under the action of the gravity of the flood, the lifting bottom layer 2 and the base layer 1 continuously displace relatively until the reset bolt 19 is not pressed by the base layer 1, the reset spring 20 acts on the reset bolt 19 to press the linkage shaft 18 downwards, so that the rigid closed supporting structure I27 and the rigid closed supporting structure II 25 are limited by the slide 30 and the limit column 29 driving the spring limit plate 26, finally, the I-shaped rigid support is presented, and at the moment, the limit layer 24 with roughness is subjected to enough positive pressure of the rigid closed support structure I27 and the rigid closed support structure II 25 to cause the support columns I9 and II 10 to be locked with each other, so that the support contraction device 7 starts to play a supporting role. Along with the continuous rising of the flood water level, when the flood water level reaches the height of the automatic air hole adjusting device 11 in the lifting bottom layer 2, the air hole buoyancy plate 13 slides along the air hole limiting structure 15 along with the rising of the flood water until the air hole 8 is sealed by the air hole closing plate 14. The flood water level continues to rise and can promote lift top layer 3 to climb along the top of lift bottom layer 2 under the guide of limit structure 5 and spout structure 6, and the flood gets into the inside of lift top layer 3 through into water grid 4, makes the exhaust hole 8 of the inside gas pocket automatic regulating apparatus 11 of lift top layer 3 close until the water level. When the flood level descends, the air hole buoyancy plate 13 descends along with the water level, the air hole 8 is opened, flood in the lifting top layer 3 can be smoothly discharged through the water inlet grille 4, the lifting top layer 3 and the lifting bottom layer 2 return to the original positions under the action of gravity along with the descending of the water level, when the lifting bottom layer 2 moves relative to the base layer 1, the reset bolt 19 is gradually pressed by the base layer 1 to displace, the reset spring 20 is pressed, the linkage shaft 18 rotates along with the reset bolt 19 along the retention support 17 to lift, at the moment, the support balance of the rigid closed support structure I27 and the rigid closed support structure II 25 is broken, along with the limitation and guidance of the slide way 30 by the limit column 29, the rigid closed support structure I27 and the rigid closed support structure II 25 are relatively folded, the pressure borne by the limit layer 24 is reduced, and the support column I9 and the support column II 10 are released from a relative locking state, after the water in the support post II 10 is slowly drained from the drainage hole 31, the support post II 10 is lifted by the spring 16 to be recovered to the original position. When the flood flows back to the lower part of the lifting bottom layer 2, the flood in the lifting bottom layer 2 is discharged through the water inlet grille 4 and returns to the original position under the action of gravity.
