Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-2, the embodiment of the invention provides a bridge deck pavement construction method, which mainly comprises the following steps:
The first step: prefabricating a T beam 1;
and a second step of: the construction of a cast-in-situ layer 10 is carried out on the top surface of the T beam 1, and a cast-in-situ layer 11 is left on the two end heads of the T beam 1 and the flange plate edges of the left and right sides respectively;
And a third step of: and hoisting the T beam with the cast-in-situ layer 10 on the bridge deck bent cap 2 step by step, and carrying out cast-in-situ layer construction on the cast-in-situ layer post construction width 11 reserved between the adjacent T beams 1.
Further, when the T beam 1 is prefabricated, a T beam top plate reinforcing steel bar 12 is reserved on the top surface of the T beam 1, as shown in fig. 2, the T beam top plate reinforcing steel bar 12 is reserved on the top surface of the T beam 1 outside the construction width 11 after the cast-in-situ layer is arranged, and the part of the T beam top plate reinforcing steel bar 12 exposed out of the top surface of the T beam 1 is semicircular and is provided with a downward opening.
The method for carrying out cast-in-situ layer construction on the top surface of the T beam 1 comprises the following steps: firstly, reserving a T beam top plate steel bar 12 on the top surface of a T beam 1, and connecting a cast-in-situ layer steel bar net 13; then, the cast-in-place layer concrete 14 is poured again. When the cast-in-situ layer 10 is constructed on the top surface of the T beam 1, the end head and the flange plate edge of the T beam 1 are respectively left 30cm wide and are not poured, so that the construction is convenient to complete after the subsequent erection, the construction is carried out together with the rest cast-in-situ layer, and the effective connection with another T beam can be enhanced.
In addition, in the process of hoisting the T beam 1 with the cast-in-situ layer on the bridge deck bent cap step by step, the cast-in-situ layer on the top surface of the front-span T beam 1 after hoisting can be used as a bridge deck transported by the girder transporting vehicle 3, and when the girder transporting vehicle 3 transports the rear-span T beam to be hoisted, the T beam can walk on the front-poured surface layer, so that the danger that a Liang Chelun tire is punctured by original outcrop steel bars is avoided.
Therefore, by adopting the bridge deck pavement construction method, after the first span T beam 1 is erected, when the next span T beam 1 is erected, a transportation beam vehicle (gun carriage) can walk on the middle two T beams. The time for processing the T-beam top plate steel bars is saved, and the transportation of the T-beam is accelerated.
