Expansive soil roadbed chemical agent grouting construction method
The embodiment of the invention provides an expansive soil roadbed chemical agent grouting construction method, and relates to the field of expansive soil road modification. The method comprises the following steps: A, measuring the free expansion rate of the soil stabilizer and the polypropylene fiber in a dry environment; step B, respectively mixing a soil stabilizer and polypropylene fibers with expansive soil, and then carrying out a water stability test and an unconfined compressive strength test; c, the optimal dilution ratio of the single-doped soil stabilizer and the optimal fiber mixing amount of the single-doped polypropylene fiber are analyzed and determined according to the measured free expansion rate and the test result, the unconfined compressive strength of the expansive soil obtained after composite improvement can be effectively improved, and the strength attenuation rate is inhibited; the expansive soil is fine, the microcosmic fracture expansion rate is effectively controlled, the purpose of safe and comfortable driving can be achieved while the stability of a roadbed and the pavement flatness of a road in a long time can be guaranteed by using the improved expansive soil, and a series of engineering problems caused by the expansive soil roadbed must be solved.
本申请实施例提供膨胀土路基化学剂注浆施工方法,涉及膨胀土路改性领域。其包括步骤A,在干燥环境下测量土壤稳定剂与聚丙烯纤维的自由膨胀率;步骤B,将土壤稳定剂、聚丙烯纤维分别与膨胀土混合后进行水稳试验及无侧限抗压强度试验;步骤C,根据测定的自由膨胀率以及试验结果分析确定单掺土壤稳定剂的最优稀释比及单掺聚丙烯纤维的最佳纤维掺量,该方法能有效提高复合改良后膨胀土的无侧限抗压强度,且强度衰减速率得到抑制,膨胀土细、微观裂隙扩展速率得到有效控制,用改良后的膨胀土能够保证道路在较长时间内路基的稳定和路面平整度的同时,还能够达到安全、舒适行车的目的,必须解决因膨胀土路基而造成的一系列工程问题。
