Coastal fine sand roadbed rolling method
The invention provides a coastal fine sand roadbed rolling method. The method comprises the following steps: determining road characteristics of sand materials of the coastal fine sand road, and paving the sand materials on a roadbed; a crawler dozer or a crawler excavator is adopted for leveling and stabilizing the pressure of the sand on the coastal fine sand roadbed; a coastal fine sand roadbed is rolled by adopting a double-steel-wheel road roller, and the double-steel-wheel road roller is used for rolling by adopting a mode of combining static pressure and vibration pressure. Detecting the compaction settlement difference parameter of the roadbed, judging whether the compaction settlement difference parameter reaches the control standard of the compaction settlement difference, and if so, ending the rolling; otherwise, rolling is continuously conducted according to the original construction technology. According to the construction method, the limitation that the roadbed filler needs to be rolled by a heavy vibratory roller under the optimal water content in the traditional construction process is broken through, the coastal fine sand filler can be filled while being excavated on the basis of ensuring the quality of the coastal fine sand roadbed, and the construction efficiency is greatly improved on the basis of stabilizing the pressure of a crawler dozer or an excavator. And a double-steel-wheel road roller is adopted for rolling.
本发明提供了一种滨海细砂路基碾压方法。该方法包括：确定滨海细砂路的砂料的路用特性，在路基上摊铺砂料；采用履带式推土机或者履带式挖掘机对滨海细砂路基上的砂料进行推平和稳压；采用双钢轮压路机对滨海细砂路基进行碾压，并且双钢轮压路机采用静压和振压相互结合的方式进行碾压。检测路基的压实沉降差参数，判断是否达到压实沉降差的控制标准，如果是，则碾压结束；否则，继续按照原施工工艺进行碾压。本发明突破了传统施工工艺规定路基填料要在最佳含水率下采用重型振动压路机进行碾压的限制，可以在保证滨海细砂路基质量的基础上，实现了滨海细砂填料随挖随填，在履带式推土机或挖掘机稳压的基础上，采用双钢轮压路机进行碾压。
