Construction method of soft soil roadbed
The invention discloses a construction method of a soft soil roadbed, and relates to the field of roadbed construction, and the construction method is characterized in that the roadbed comprises an original roadbed, a prefabricated part layer is arranged on the upper surface of the original roadbed, a gravel layer is arranged on the upper surface of the prefabricated part layer, and a sand cushion layer is arranged on the upper surface of the gravel layer. The foundation physical performance of the soft soil roadbed is improved through ultrasonic reinforcement, vibration is transmitted into the soil layer, the fault zone can be sunk to the expected position again, the tightness of the loose soil layer is improved, and therefore the stability and the bearing capacity of the soft soil roadbed are improved. In the sixth step, a plurality of anti-skid grooves can be formed in the original roadbed, after the prefabricated part layer is placed on the original roadbed, the friction force between the prefabricated part layer and the original roadbed can be increased, the situation that the prefabricated part layer slides laterally and loses the supporting effect on all the layers above is avoided, and the roadbed stability is improved.
本发明公开了一种软土路基的施工方法,涉及路基施工领域,其技术方案要点是:其路基包括原始路基,原始路基的上表面设置有预制构件层,预制构件层的上表面设置有碎石层,碎石层的上表面设置有砂垫层,本发明经过步骤1‑8,超声加固改善软土路基的地基物理性能,通过振动传导到土层内部,可以使断裂带区重新沉位到预期位置并增加松散土层的紧固性,从而提高软土路基的稳定性和承载能力;步骤6能够在原始路基上形成有若干防滑槽,当预制构件层放置在原始路基上后,能够增加预制构件层和原始路基之间的摩擦力,避免预制构件层产生侧向滑移而失去对上方各层的支撑作用,增加了路基稳定性。
