Embodiment Construction

[0024] The present invention will be further elaborated below in combination with specific embodiments.

[0025] As shown in the figure: a bridge deck cross-slope adjustment structure, which includes a cover beam 1, a pad stone layer 2, a support 3, a prefabricated beam slab 4, hinge joints 5, and a bridge deck pavement layer 6 arranged on the bridge pier and the asphalt concrete layer 7, the pad stone layer 2 is arranged on the top of the cap beam 1, the pad stone layer 2 is stepped along the bridge deck transverse slope direction, and each step of the pad stone layer 2 corresponding to the top of each pier is provided with There are two supports 3 whose top and bottom surfaces are kept horizontal and have the same thickness, each pair of supports 3 is supported on both sides of the bottom surface of one end of the prefabricated beam slab 4, and each pair of supports 3 is arranged symmetrically along the width direction of the prefabricated beam slab 4 , hinge joints 5 are ar...

Abstract

The invention relates to a bridge deck cross-slope adjustment structure and laying method. The bridge deck cross-slope is realized by a series of slope-adjusting components including a cover beam with a cross-slope, a stepped pad stone layer, a prefabricated beam of equal height, and a slope-adjusting bridge deck pavement layer. The setting; this structure is suitable for bridges with prefabricated construction, bridges with wide bridges or super high transverse slope characteristics. The top surface of each level of pad stone is horizontal to ensure that the support and beam slab are placed horizontally; the steps on the top surface of each beam slab are staggered to form a slope; The top surface of the loading layer is a transverse slope; the structure method of the invention is reasonable and ingenious, and the dead load on the top surface of each prefabricated beam slab is the same, which is beneficial to the standardized construction of the prefabricated beam slab and is convenient for construction; it not only ensures the designed transverse slope of the bridge deck, but also reduces the prefabricated The self-weight load of the cast-in-place concrete layer on the top surface of the beam slab.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a bridge deck transverse slope adjustment structure and a laying method. Background technique [0002] The setting of bridge deck cross slope is mainly for the need of bridge deck drainage, usually set 1.5%~2% bridge deck cross slope. It is mainly used to confluence the rainwater accumulated on the bridge deck to the edges of both sides of the bridge deck roadway, and then the rainwater is concentrated and discharged from the bridge deck by the water collecting pipe. The consequences of pouring a half-width cross-slope cushion on the top of the slab girder are: as the number of carriageways increases and the width of the bridge deck increases, the self-weight load of the reinforced concrete cross-slope cushion increases accordingly, and the top surface of each prefabricated beam The thickness difference of the pavement layer increases; on the other hand, when the bridg...
