Embodiment Construction

[0046] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0047] see Figure 1 to Figure 7 As shown, the present embodiment provides a bridge deck drainage system 1000. The bridge 30 where the bridge deck drainage system 1000 is located is provided with a sidewalk 31. , vertical drain pipe 6, drain pipe 7;

[0048] The bridge deck water collection well includes a well base 2 and a well cover 3; The side is provided with a drainage outlet 101, and components such as a drainage grille are used at the drainage outlet to filter and drain water.

[0049] Due to the wide sidewalks, the bridge deck water collection wells 1 in this embodiment are arranged at intervals along the bridge central axis. Located within the thickness range of the bridge deck pavement, the water inlet grille on the manhole cover 3 leans against the edge of the sidewalk, which is convenient for water collection du...

Abstract

The invention discloses a bridge floor drainage system which comprises a bridge floor water collecting well for lateral drainage, a transverse drainage pipe, a longitudinal drainage pipe and a water drainage pipe. The bridge floor water collecting well comprises a well base and a well lid. The well lid is provided with a water inlet; a water outlet is formed in the side surface of the well base; the bridge floor water collecting well is positioned above a main beam box chamber and is communicated with the transverse drainage pipe; the transverse drainage pipe is communicated with the longitudinal drainage pipe; the water drainage pipe penetrates through the main beam cantilever arm, the upper end of the water drainage pipe is communicated with the longitudinal water drainage pipe, and thelower end of the water drainage pipe is located below a bridge floor. According to the bridge floor drainage system provided by the invention, by arranging the water collecting well for lateral drainage and the corresponding drainage pipe, the bridge floor drainage and drainage mode is improved, and the damage to the box chamber structure of a bridge girder due to the fact that the drainage pipe is vertically arranged on the bridge with the sidewalk is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge auxiliary structure design, in particular to a bridge deck drainage system. Background technique [0002] Bridge deck drainage is an important part of bridge accessory design, and also an important factor affecting bridge structural performance and durability. At present, most urban bridges except elevated expressways are equipped with sidewalks. The bridge deck drainage system is usually set at the lowest point of the cross slope of the bridge deck, that is, at the junction of the roadway and the sidewalk, and the bridge deck water collection well is installed, and the corresponding drainage system is laid. The pipes lead the water from the bridge to the ground rainwater well under the bridge. When the sidewalk width is greater than the cantilever length of the main girder structure of the bridge, if the vertical drainage method is adopted directly from the water collecting well on the bridge dec...
