Description

Technical Field

[0001] The utility model relates to a water intercepting device, in particular to a water intercepting groove at the abutment, belonging to the technical field of bridges. Background Art

[0002] For a normally operating bridge, the rubber water stop of the expansion joint at the abutment is prone to aging and damage, and the concrete in the anchorage area is also prone to cracking and damage, resulting in rainwater on the road surface and bridge deck can seep through the expansion joint, causing scouring of the front slope, affecting the beauty and durability of the slope. Long-term scouring may even pose a greater safety hazard. Especially for bridges erected on sections with large longitudinal slopes and long downhill sections, as well as bridges with conical slopes protected by hollow hexagonal blocks, the catchment area at the bridgehead is large, and it is more likely to cause serious scouring of the front slope and pose a greater safety hazard.

[0003] To address this problem, it is necessary to replace the rubber water stop of the expansion joint in a timely manner during daily maintenance, repair the concrete in the anchorage area in a timely manner, and repair the scoured front slope in a timely manner. However, due to factors such as the narrow construction space of the expansion joint and the large pressure of maintaining traffic on the normally operating highway, it is often impossible to repair the rubber strip, the concrete in the anchorage area, and the front slope in a timely manner, which results in long-term scouring of the abutment slope, and small diseases gradually develop into larger diseases.

[0004] Therefore, it is necessary to design an effective water intercepting groove at the abutment to solve this problem. Content of the Utility Model

[0005] The utility model mainly aims at the above problems existing in the prior art, and provides a water intercepting groove at the abutment.

[0010] Preferably, a first reinforcing plate is connected between the side wall of the L-shaped fixing bracket and the first fixing steel bar.

[0011] Preferably, the water diversion trough adopts a U-shaped trough structure.

[0012] Preferably, the second fixing assembly includes a plurality of second fixing steel bars and U-shaped fixing brackets uniformly arranged along the length direction of the water diversion trough.
