[0027] Here, the high structure 001 and the low structure 002 are disconnected because of different buried depths, structural arrangements and basement bearing layers, such as membrane pools and AO biological pools in sewage treatment plants, so the settlement joint 004 between structures can effectively realize this function, and the stress system of the separated structure is independent, and stress concentration and local structure cracking caused by stress concentration do not occur, thereby affecting the safety of the structure.
[0028] In one or more embodiments of the utility model, the high structure 001 includes a partition wall 1, a partition plate 2, a high outer wall 3, a water weir 4 and a high bottom plate, the partition wall 1 is arranged on the side of the high outer wall 3 away from the water receiving groove 03, and the partition wall 1 is a partition component and a vertical bearing component, the lower end of which is connected with the high bottom plate, mainly bearing water pressure, the wall thickness of which is generally not less than 1 / 10 of the height, and the reinforcement is determined according to the most unfavorable bending moment and shear force of the cross section; the high outer wall 3 is arranged adjacent to the low structure 002, and the high outer wall 3 and the low structure 002 form the settlement joint 004, the water weir 4 is arranged on the upper end of the high outer wall 3, the partition plate 2 is arranged between the partition wall 1 and the upper part of the high outer wall 3, the backflow pump 01 is arranged between the partition wall 1 and the high outer wall 3, and the upper end of the backflow pump 01 is fixed in the partition plate 2, the partition plate 2 is used for fixing the backflow pump 01, and the water area is divided into two zones, generally with a thickness of 250-300mm; the partition wall 1, the partition plate 2 and the water weir 4 form the water passing groove 02 located on the upper part of the high structure 001, and the water outlet of the backflow pump 01 is communicated with the water passing groove 02.
