Bridge deck transverse slope regulating structure and paving method

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...

Problems solved by technology

[0003] Aiming at the problem that the increase of the width of the bridge deck and the increase of the transverse slope in the above-mentioned prior art will greatly increase the dead load of the bridge deck pavement cushion, and at the same time bring about the problem of partial distribution of the dead load, the present invention provides a bridge deck transverse slope Adjust structure and laying method
