[0026] The enclosure 6 is fixedly installed on the upper outer surface of the floor 7, and the floor 7 is fixedly installed on the upper part of the inner cavity of the sedimentation tank 1, and the triangular plate 10 is fixedly installed on the upper outer surface of the enclosure 6; the drain outlet 9 is opened on the outer surface of one end of the enclosure 6, and the water outlet 2 is located at one end of the drain outlet 9, the constant pressure hole 8 is opened on the lower outer surface of the floor 7, and the constant pressure hole 8 is connected to the inner cavity of the enclosure 6; the upper crossbeam 12 passes through the lower fixed frame 11, and the outer wall of the upper crossbeam 12 is fixedly connected to the lower fixed frame 11, and the outer surfaces of both ends of the upper crossbeam 12 are fixedly connected to the inner wall of the sedimentation tank 1; the lower crossbeam 13 is located at the lower part of the upper crossbeam 12, and the outer surfaces of both ends of the lower crossbeam 13 are fixedly connected to the inner wall of the sedimentation tank 1; the upper hanging ring 14 is fixedly installed on the lower outer surface of the upper crossbeam 12, the lower hanging ring 15 is fixedly installed on the upper outer surface of the lower crossbeam 13, and the wire rope 16 is fixedly installed between the upper hanging ring 14 and the lower hanging ring 15.

[0027] It should be noted that the utility model is a municipal sewage treatment sedimentation tank. As the liquid inside the sedimentation tank 1 increases, the upper layer of liquid enters the interior of the enclosure 6 through the position of the triangular plate 10 for diversion, and is discharged into the diversion trough 3 through the position of the drain port 9 and the outlet 2. Because the liquid inside the sedimentation tank 1 exerts an upward buoyancy on the bottom of the overflow weir assembly 4, by opening a constant pressure hole 8 at the bottom of the floor 7, the buoyancy of the liquid on the overflow weir assembly 4 can be reduced, thereby playing a protective role; through the setting of the reinforcement frame 5, the upper crossbeam 12 passes through the lower fixed frame 11 and is fixedly connected, and the overflow weir assembly 4 can be strengthened by the upper crossbeam 12 to improve the stability of the overflow weir assembly 4, and the setting of the lower crossbeam 13, the upper crossbeam 12 and the lower crossbeam 13 are connected by a wire rope 16, so as to further increase the stability of the overflow weir assembly 4 and avoid the instability of the overflow weir assembly 4 due to the action of buoyancy.
