Soft foundation replacement and filling structure and construction method thereof
The invention discloses a soft foundation replacement and filling structure which is sequentially provided with an original roadbed treatment layer, a foam concrete layer and a pavement structure 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 precast 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 a pavement structure layer. When the soft foundation replacement and filling 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.
本发明公开了一种软基换填结构，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结构层；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预制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)铺设路面结构层，即得。本发明软基换填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。
