The invention belongs to the technical field of roads and bridges, and particularly relates to a single-span seamless abutment-free bridge. The bridge structure comprises a bridge body, end cross beams, supporting blocks, soil retaining plates and bridge head guide plates. The beam bodies are connected in series into a whole through the end cross beams; the end cross beam is higher than or equal to the beam body, and the width of the end cross beam meets the foundation pile top supporting requirement; in the cross section of the bridge, supporting blocks and supports are arranged downwards from the bottoms of the end cross beams at the positions corresponding to the pile positions, the supports are placed at the tops of the piles, and the vertical load of the bridge is transmitted to the pile foundations through the supporting blocks, the supports and the padstones; on the side, close to the roadbed, of the pile foundation, a soil retaining plate extends downwards from the end cross beam, and the soil retaining plate is connected with the end cross beam and the supporting block; bridge head guide plates are placed on end cross beam brackets, and seamless connection between the tail ends of the guide plates on the two sides of a bridge span is achieved. The engineering problem that a telescopic device needs to be maintained and replaced regularly is solved, and the integrity of the bridge is good; the lower structure is only composed of the pile foundations, and the material consumption and the construction work amount can be greatly saved.
本发明属于路桥技术领域，具体为一种单跨无缝无桥台型桥梁。本发明包括桥梁梁体、端横梁、支承块、挡土板、桥头引板；端横梁将各梁体串联成整体；端横梁高度大于或等于梁体高度，端横梁宽度满足基桩顶部支承要求；桥梁横断面中，在与桩位相对应位置，从端横梁底向下为支承块、支座，支座搁置于桩顶，桥梁的竖向荷载通过支承块、支座及垫石传至桩基；在桩基靠路基侧，由端横梁下伸有挡土板，挡土板与端横梁、支承块相接；桥头引板搁置于端横梁牛腿上，实现桥跨两侧引板末端间无缝连接。本发明中没有伸缩装置需要定期维修、更换的工程问题，桥梁整体性好；下部结构仅由桩基组成，可大大节约材料用量和施工工程量。
