The invention relates to a high-pressure accumulator (1) for internal combustion engines for storing highly pressurized fuel. The high-pressure accumulator (1) comprises an accumulator pipe (2) with an accumulator chamber (3) formed in the accumulator pipe (2). The high-pressure accumulator (1) comprises a supply connection (7) for supplying highly pressurized fuel and at least one discharge connection (4) for discharging highly pressurized fuel. A honeycomb structure (10) is arranged in the accumulator chamber (3).

Provided is a bridge expansion joint structure, comprising a bridge body (2, 3) and an expansion joint (1). The expansion joint (1) divides the bridge body (2, 3) into a first bridge body (2) and a second bridge body (3). A first bearing step (21) is formed on the first bridge body (2), and the first bearing step (21) is provided with a first fixed pillar (22). A second bearing step (31) is formed on the second bridge body (3), and the second bearing step (31) is provided with a second fixed pillar (32). Lateral faces of the first and second bearing steps (21, 31) are respectively fixedly connected to a C-shaped steel plate (4). An expansion joint connector (6) is provided between the first bridge body (2) and the second bridge body (3). The expansion joint connector (6) comprises an upper bearing body (61) and a lower supporting body (62), and the upper bearing body (61) and the lower supporting body (62) are both provided with reinforcing ribs (63). A cover plate (7) is provided above the expansion joint (1). Elastic filling materials (8) are filled between the expansion joint (1) and the expansion joint connector (6). The bridge expansion joint structure meets the requirement of road expansion deformation, is structurally secure, has a good bearing capacity, provides a good smooth and comfortable sensation during driving, and is also easy and convenient to install, inspect and maintain.
