Semi-rigid base layer for preventing bumping at bridgehead and construction process
The invention discloses a semi-rigid base layer for preventing bumping at bridgehead and a construction process. A first rigid base layer is fixedly connected with a bridgehead transition slab, a common base layer is fixedly connected with the first rigid base layer, a first semi-rigid base layer is fixedly connected with the first rigid base layer, and a second rigid base layer is fixedly connected with the first semi-rigid base layer; the first semi-rigid base layer is fixedly connected with the first rigid base layer, the second semi-rigid base layer is fixedly connected with the second rigid base layer, an asphalt concrete surface layer is fixedly connected with the second semi-rigid base layer, a first geogrid is fixedly connected with the first semi-rigid base layer, and a second geogrid is fixedly connected with the second semi-rigid base layer; the first semi-rigid base layer and the second semi-rigid base layer are formed by matching lime, fly ash and gravel, one side of the first semi-rigid base layer and one side of the second semi-rigid base layer are connected with the bridge end transition slab, and the other side of the first semi-rigid base layer and the other side of the second semi-rigid base layer are connected with the common base layer, so borne loads are evenly distributed, and a real transition section is formed between the bridge end transition slab and the common base layer; and a problem of non-uniform settlement between the bridge abutment and the embankment is solved.
本发明公开了一种防止桥头跳车的半刚性基层及施工工艺，通过第一刚性基层与桥头搭板固定连接，普通基层与第一刚性基层固定连接，第一半刚性基层与第一刚性基层固定连接，第二刚性基层与第一半刚性基层固定连接，第二半刚性基层与第二刚性基层固定连接，沥青混凝土面层与第二半刚性基层固定连接，第一土工栅格与第一半刚性基层固定连接，第二土工栅格与第二半刚性基层固定连接，其中第一半刚性基层和第二半刚性基层均由石灰、粉煤灰、碎石组配而成，第一半刚性基层和第二半刚性基层一侧与桥头搭板连接，另一侧与普通基层连接，使受到的荷载均匀分布，在桥头搭板和普通基层之间形成真正的过渡段，解决了桥台和路堤之间沉降不均匀的问题。
