FIG. 1 is a schematic view of a transverse bridge elevation structure of the present utility model;
fig. 2 is a schematic view of a forward-bridge vertical structure of the present utility model.
Description of the embodiments
The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the labels 1-7 are shown as: the concrete tower column 1, the cross beam 2, the water retaining table 3, the drain pipe 4, the transverse drainage slope 5, the longitudinal drainage slope 6 and the inward longitudinal slope 7.
Examples: as shown in fig. 1 and fig. 2, the drainage structure of the cable-stayed bridge anti-icing design in this embodiment is used for solving the influence of the ice falling at the cable-stayed bridge tower beam position on the bridge deck driving safety.
Specifically, the cable-stayed bridge comprises a plurality of concrete towers 1 for supporting, wherein cross beams 2 are erected between the adjacent concrete towers 1, and the cross beams 2 can connect the adjacent concrete towers 1 to form an integral structure. The two sides of the cross beam 2 along the bridge direction are respectively provided with a water retaining table 3 extending along the cross bridge direction, and the water retaining tables 3 on the two sides are higher than the beam surface of the cross beam 2 by a certain height so as to play a role in retaining water. An inward longitudinal slope 7 is arranged at the top of the water baffle table 3, and the slope direction of the inward longitudinal slope 7 is shown as an arrow direction in fig. 2, namely, the direction of the arrow is from outside to inside on a forward bridge. The transverse bridge direction and the forward bridge direction of the cross beam 2 are respectively provided with a transverse drainage slope 5 and a longitudinal drainage slope 6, and the slope directions of the transverse drainage slope 5 and the longitudinal drainage slope 6 are shown as arrow directions in fig. 2. A drain pipe 4 is embedded in the cross beam 2, one end opening of the drain pipe 4 is positioned on the inner side of the water blocking table 3 and is exposed on the beam surface of the cross beam 2, and the other end opening is arranged in an area outside the operation range of the bridge deck traffic line.
When the novel ice bank is applied, the inward longitudinal slope 7 of the water baffle table 3 melts snow on the top of the water baffle table 3 and then inwards collects the snow in the range of the cross beam 2, so that the occurrence of ice bank outside the cross beam is prevented. The transverse drainage slope 5 and the longitudinal drainage slope 6 of the cross beam 2 utilize the gradient thereof to melt snow and then the formed rainwater is discharged out of the operation range of the bridge deck traffic lane by utilizing the drain pipe 4, so that the influence of ice falling formed by melting snow on the bridge deck traffic safety is avoided.
In this embodiment, the drainage structure mainly realizes two parts of functions, and on one hand is "fender", namely through setting up manger plate platform 3 structure and crossbeam 2 avoid snow to melt and form the ice to fall down further to within the bridge floor driving line scope, on the other hand is "row", namely with the water after the ice melts accessible drain pipe 4 orderly discharge outside bridge floor driving line operation scope, also can avoid driving line to lead to the increase of driving risk because of ponding.
The embodiment is implemented in specific manner: as shown in fig. 1 and 2, four drain pipes 4 are pre-buried in the cross beam 2 in this embodiment, and the four drain pipes 4 are symmetrically arranged at four corners of the cross beam 2, so as to improve drainage efficiency and avoid water accumulation on the cross beam 2 after snow is melted. However, in actual engineering, the number and positions of the drain pipes 4 can be adaptively adjusted according to actual conditions.
Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
