Foam concrete railroad bed structure and construction method thereof
The invention discloses a foam concrete railroad bed structure. The foam concrete railroad bed structure is sequentially provided with a plurality of jet grouting piles or miniature steel pipe piles,a cushion layer, an impermeable layer and a foam concrete layer from bottom to top, wherein the foam concrete layer is of a frame structure formed by pouring foam concrete, or a frame structure formedby filling foam concrete precast blocks and then pouring the foam concrete. The construction method comprises the following steps of (1) prefabricating foam concrete blocks in advance for later use;(2) embedding a plurality of jet grouting piles or miniature steel pipe piles; (3) forming the cushion layer; (4) forming the impermeable layer; and (5) pouring foam concrete on the impermeable layer,or firstly building foam concrete blocks for filling and then pouring the foam concrete to form the foam concrete layer. The foam concrete does not need to be vibrated and compacted during construction, and an original roadbed is not disturbed. 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 a project is reduced.
本发明公开了一种泡沫混凝土铁路路基结构，自下而上依次设置有：若干旋喷桩或微型钢管桩、垫层、防渗层和泡沫混凝土层，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)提前预制泡沫混凝土块体，备用；(2)埋入若干旋喷桩或微型钢管桩；(3)形成垫层；(4)形成防渗层；(5)在防渗层上浇筑泡沫混凝土，或先砌筑泡沫混凝土块体填充再浇筑泡沫混凝土，形成泡沫混凝土层，即得。本发明泡沫混凝土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。
