Road widening structure and construction method thereof
The invention discloses a road widening structure which is sequentially provided with an undisturbed roadbed treatment layer, a foam concrete layer and a pavement layer from bottom to top, wherein the foam concrete layer is of a frame structure formed by pouring foam concrete, or is of a frame structure formed by firstly filling foam concrete blocks and then pouring the foam concrete. The construction method comprises the following steps: (1) excavating an original roadbed, or piling on the foundation; (2) prefabricating foam concrete; or prefabricating foam concrete and foam concrete blocks; (3) forming a foam concrete layer; and (4) paving the pavement layer. When the road widening structure is constructed, vibration and compaction are not needed, and an original roadbed cannot be disturbed; and the construction process of prefabrication and cast-in-place is adopted, so that the construction time can be greatly shortened, and the comprehensive construction cost of engineering is reduced.
本发明公开了一种道路加宽结构，自下而上依次设置有：原状路基处理层、泡沫混凝土层和路面层；其中，泡沫混凝土层是由泡沫混凝土浇筑制成的框架结构，或是先由泡沫混凝土块体填充再由泡沫混凝土浇筑制成的框架结构。施工方法：(1)原状路基开挖，或在地基上打桩；(2)预制泡沫混凝土；或，预制泡沫混凝土和泡沫混凝土块体；(3)形成泡沫混凝土层；(4)铺设路面层，即得。本发明道路加宽结构施工时无需振捣压实，对原有路基不会产生扰动；采用“预制+现浇”的施工工艺，可以大幅缩短施工时间，降低工程综合造价。
