Abstract

The invention relates to the technical field of bridge drainage and particularly relates to a drainage device of an expansion joint and the bridge expansion joint. The drainage device of the expansionjoint comprises a drainage groove pre-buried in one side of a lower portion of a gap of the expansion joint, and a flow guide structure which is pre-buried in the other opposite side below the gap ofthe expansion joint, wherein one end of the flow guide structure extends into the drainage groove, and the extension length of the flow guide structure is not smaller than the maximum expansion distance of the gap of the expansion joint. The drainage device of the expansion joint and the bridge expansion joint are thorough in drainage.

Description

technical field [0001] The invention relates to the technical field of bridge drainage, in particular to a drainage device for expansion joints and bridge expansion joints. Background technique [0002] Bridge expansion joints are very important auxiliary facilities of bridge structures, which are used to adjust the bridge deck displacement caused by vehicle loads and temperature changes, so as to adapt to the smooth passage of bridge loads. Its installation is generally completed through the slot reserved at the branch end and the embedded parts of the beam body. Due to the effect of the vehicle load on the bridge and the complex environment of the bridge deck, water leakage at the expansion joints is serious. Existing solutions include installing Z-shaped rubber belts, U-shaped aluminum plates, stainless steel waterstops or filling elastic waterproof composite materials in the gaps of expansion joints. Due to the filling of debris and stones on the bridge deck, the Z-sha...
