Weak expansive soil roadbed construction process
The invention relates to a weak expansive soil roadbed construction process. The construction process comprises the following steps: S1, treating a weak expansive soil layer, namely drawing two road lines, digging weak expansive soil between the two road lines into a mixing bin, adding lime into the mixing bin, and uniformly mixing the weak expansive soil with the lime through a stirring device, then discharging the mixture of the weak expansive soil and the lime to the position between the two road lines, and then leveling and rolling the mixture of the weak expansive soil and the lime; S2, carrying out plain soil paving and leveling on the upper surface of the weak expansion soil layer; S3, drawing a neat square grid with a standard area on the lower bearing layer in step 2, and manuallyand uniformly spreading cement in each square grid according to the cement mixing amount per square meter; S4, using a road mixer to mix the plain soil and cement; and S5, leveling and rolling the plain soil cement mixture. The weak expansive soil layer can be conveniently treated.
本申请涉及一种弱膨胀土路基施工工艺，其包括以下步骤：S1、处理弱膨胀土层：先画出两条道路线，然后将两条道路线之间的弱膨胀土挖至拌合仓里，然后将石灰加入拌合仓里，接着通过搅拌装置使弱膨胀土与石灰混合均匀，随后将弱膨胀土与石灰的混合料排至两条道路线之间，接着整平并碾压弱膨胀土与石灰的混合料；S2、在弱膨胀土层上表面进行素土摊铺并整平；S3、在步骤二的下承层上画出整齐的标准面积方格网，按每平方米的水泥掺量在每个方格网内用人工将水泥撒布均匀；S4、用路拌机进行素土与水泥的拌和；S5、整平并碾压素土水泥混合料。本申请便于对弱膨胀土层进行处理。
