In order to better show the assembled integral four-cabin flood discharging box culvert haunching structure, the embodiment provides a construction method of the assembled integral four-cabin flood discharging box culvert haunching structure, which comprises the following steps:
s1: measuring and paying off;
s2: prefabricated bottom plate hoist and mount
When the prefabricated bottom plate is hoisted, the prefabricated bottom plate is paved according to the elastic lines through a special hoisting tool. Four-point hoisting is adopted in the hoisting process, so that stable hoisting is ensured. During hoisting, the direction of the prefabricated bottom plates is noticed, and the reserved steel bars of two adjacent prefabricated bottom plates are ensured to be positioned at the same position. Because the prefabricated concrete component is adopted, 1cm of adjusting gap is reserved between every two prefabricated bottom plates.

And finishing the hoisting of the prefabricated bottom plate and adjusting the prefabricated bottom plate in place. The gap and the position concentricity of the reserved steel bar joints of the adjacent prefabricated bottom plates are ensured to meet the technical specification of steel bar welding. When the upper bars are welded, the upper bars and the main ribs are fixed by four-point tack welding. The distance between the positioning welding line and the end part of the upper strip is preferably more than or equal to 20mm. During welding, arc striking should be carried out in a welding seam formed by the upper strip welding. And filling the arc pits before the arc is closed at the end head. And the main weld should merge with the beginning and end of the tack weld.
S4: superposed wall hoisting
S401: the special lifting appliance is adopted for lifting the superposed wall, so that the verticality of the wall body in the lifting process is ensured, and the subsequent wall body installation is facilitated. And the wall body is hoisted to ensure that the axis of the control wall is consistent with the placed line. And simultaneously controlling the elevation of two adjacent wall bodies. According to the design gradient, the elevation of the wall body is adjusted by using the sizing blocks, and the integral elevation gradient after the wall body is installed is ensured to meet the design requirement.
S402: the wall body hoisting process and the wall column splicing reinforcing steel bars are alternately constructed, one wall plate is hoisted, and the column splicing reinforcing steel bars between the two wall bodies are installed. Then the next wallboard is hoisted.
S403: and fixing the wallboard by using a processing positioning piece. 2 positioning pieces are arranged on each side of the wall board, so that the long edge of the wall board cannot move left and right. The upper end of the wallboard is fixed by 2 inclined struts.
S404: when the verticality of the inclined support is adjusted, all components on the same component rotate towards the same direction to prevent the components from being twisted. If the support is not rotated, the brute force rotation is strictly forbidden. The leakage length of the screw rod of the stay bar is observed at any time during rotation (the length of the screw rod is 500mm, and the screwing-out length is not more than 300 mm) so as to prevent the screw rod from being separated from the rotary rod.
