Background

As is well known, bridge expansion joints are continuous bridge deck constructions in which gaps are provided between two beam ends, between the beam ends and the bridge abutment, in order to allow a vehicle to smoothly pass through the bridge deck and meet the beam body deformation requirements. The expansion joint device of the highway bridge can be divided into a modular type, a comb plate type and a seamless type according to the structural type, wherein the modular expansion joint is most widely applied to the highway bridge. However, through research on a plurality of highways, the rainwater at the modular expansion joint can not be discharged in time in summer rainy season or sudden heavy rain, so that the bridge floor is seriously accumulated, and great potential safety hazard exists when the vehicle runs.

Disclosure of utility model

The utility model aims to solve the problems that the existing modular expansion joint cannot timely drain rainwater, which is easy to cause serious accumulated water on a bridge deck and affects the safe running of a vehicle, and designs a bridge expansion joint structure with a drainage device, which can drain water timely.

The utility model provides a take drainage device's bridge expansion joint structure, it includes girder 1, and girder 1 frame dress is on pier bent cap 14, and pier bent cap 14 installs on pier stand 15, characterized by: two sides of the joint 2 of the adjacent girders 1 are respectively provided with a longitudinal girder 3, the longitudinal girders 3 are fixed on the girders 1 through anchoring structures 4, and the anchoring structures 4 are fixed on the girders 1; the both sides of rubber seal area 5 inlay and install in corresponding longeron 3, and the one end of rubber seal area 5 is connected with rubber water drain pipe 10, and in the lower extreme of rubber water drain pipe 10 inserted PVC water collector pipe 11, PVC water collector pipe 11 passes through lifting hook 13 to be fixed on pier capping beam 14 and pier stand 15 and extend to in the ground drainage facility.

The anchoring structure 4 comprises a connecting steel plate 6, a reinforcing steel bar connecting piece 7 and backfill concrete 8, wherein the connecting steel plate 6 is arranged on the girder 1, the girder 3 is supported on the connecting steel plate 6, one end of the reinforcing steel bar connecting piece 7 is pressed on the girder 3, the other end of the reinforcing steel bar connecting piece 7 is inserted into the girder 1, and the connecting steel plate 6 and the reinforcing steel bar connecting piece 7 are fixed on the girder 1 by the backfill concrete 8 and are flush with the bridge deck pavement layer 9.

The cross section of the rubber sealing belt 5 is of a V-shaped structure.

The water inlet end of the rubber drain pipe 10 is provided with an anti-sundry grille structure 12.

The utility model has the beneficial effects that:

Compared with the traditional modulus expansion joint, the utility model adopts the flexible drain pipe made of neoprene to connect the bridge deck rubber sealing belt, and timely drains the bridge deck ponding at the expansion joint, thereby eliminating the potential safety hazard of driving in rainy days, and the flexible drain pipe has large compression deformation, can meet the deformation requirement of the beam body, adopts the PVC pipeline to connect with the flexible drain pipe, collects the bridge deck rainwater in a concentrated way, and avoids the rainwater from invading the structures such as the support, the bent cap, and the like.
