Description

Technical Field

[0001] This utility model relates to the technical field of bridge engineering technology and related fields, and in particular to a transverse drainage outlet for bridge deck. Background Technology

[0002] Bridge deck drainage facilities are a very important part of bridge construction. If the bridge deck drainage is not smooth, serious traffic accidents such as vehicle skidding or overturning are likely to occur. On the other hand, it may also cause a series of water damage hazards to the bridge, seriously affecting the bridge's durability.

[0003] The main method of bridge deck drainage is through the longitudinal and transverse slopes of the bridge deck. Rainwater is collected by drainage ditches and drain pipes on the lower side of the cross section and then discharged into the ground drainage system.

[0004] In recent years, due to the development of traffic volume, especially urban bridges, there are more and more wide bridges, some of which are even more than 40 meters wide. Pedestrian and non-motorized vehicle lanes are often arranged on both sides of these bridges. For safety reasons, crash barriers are usually installed between the roadway and the pedestrian and non-motorized vehicle lanes. However, rainwater from the bridge surface of the motorized vehicle lane is blocked by the crash barriers and cannot enter the rainwater collection system arranged on the side of the pedestrian and non-motorized vehicle lanes.

[0005] Currently, a common solution is to install transverse drainage outlets at the bottom of the crash barrier to drain rainwater from the roadway into the non-motorized vehicle lane. The rainwater is then collected by a drainpipe on the non-motorized vehicle lane side and discharged into the surface drainage system. This method is simple in construction, but traditional transverse drainage outlets can only handle water from the bridge surface and cannot accommodate water seeping into the interlayer beneath the bridge pavement. Therefore, longitudinal drainage blind drains are usually required to drain this interlayer water. However, these longitudinal drainage blind drains often have poor drainage performance because they rely solely on the longitudinal slope. Utility Model Content

[0007] Water collection steel trough, drainage flat pipe, at least one seepage spring steel pipe, first grating, second grating;

[0008] The lower surface of the water collection steel trough and the lower surface of the drainage flat pipe are both installed on the upper surface of a main beam.

The left end of the seepage spring steel pipe is located inside the water collection steel trough, and the right end of the seepage spring steel pipe extends into the bridge deck. Concrete crash barriers are poured around the water collection steel trough and around the drainage flat pipe.

[0012] In the aforementioned transverse drainage outlet for a bridge deck, the lower edge of the mounting hole is lower than the upper surface of the bridge deck.

[0013] The aforementioned bridge deck transverse drainage outlet further includes: a plurality of first pins, the left ends of which are installed on the outer edge of the first grille, and the right ends of which are installed inside the concrete crash barrier.
