Construction method for sandy soil roadbed filling
The invention relates to a construction method for sandy soil roadbed filling. The method mainly comprises the following steps: detecting the content and an optimal water content of particles with different particle sizes in sandy soil, and determining the type and rolling water content of the sandy soil; paving and levelling sandy soil on a roadbed, building small water retaining dams above the sandy soil, injecting water into grids defined by the small water retaining dams, vibrating the grids, draining redundant water after the sandy soil is saturated, and cleaning the small water retainingdams; and after the water content of the sandy soil is stabilized to a rolling water content, rolling the sandy soil through a road roller. Compared with the prior art, the method has the advantagesthat the content of particles with different particle sizes in sandy soil is detected, the type of the sandy soil is determined, the proper rolling water content is selected for different types of sandy soil, then water injection rolling is conducted, the compactness of the sandy soil can be effectively improved, and the quality of a roadbed is also improved.
本发明涉及一种砂土路基填筑的施工方法，主要包括以下步骤：检测砂土不同粒径颗粒的含量和最佳含水量，确定砂土的种类和碾压含水量；将砂土在路基上摊铺整平，在砂土上方修筑挡水小坝，在挡水小坝围成的方格内注水并捣振，砂土饱水后排去多余水并清理挡水小坝；待砂土含水量稳定至碾压含水量后，通过压路机对砂土进行碾压。与现有技术相比，本发明首先检测砂土不同粒径颗粒的含量，确定砂土的种类，为不同种类的砂土选择合适的碾压含水量，再注水碾压，能有效提高砂土的压实度，也提升了路基的质量。
