Construction method of cement soil roadbed on expressway
The invention relates to the technical field of cement soil roadbed construction, in particular to a construction method of a cement soil roadbed on an expressway, which comprises the following steps: S1, cleaning the surface of a roadbed; S2, measuring and lofting; S3, installing a first-layer soil protection structure; S4, filling the first-layer soil protection structure with a mixture layer by layer, and paving and rolling the mixture layer by layer; S5, sprinkling water; S6, installing a second-layer soil protection structure, specifically, installing the second-layer soil protection structure on the top of the first-layer soil protection structure; S7, performing mixture paving and rolling, specifically, filling the second-layer soil protection structure with the mixture layer by layer, and performing paving and rolling layer by layer; S8, performing water spraying: uniformly spraying water to the surface of the rolled mixture to keep the water content of the mixture within a proper range; S9, repeating the steps S6-S8 until the roadbed thickness reaches the designed thickness; and S10, performing side slope construction: constructing the side slopes on the two sides of the roadbed. According to the construction method, the loosening and loss of the cement soil roadbed caused by rain wash can be reduced, the strength of the cement soil roadbed is improved, and the safety of vehicle driving is improved.
本申请涉及水泥土路床施工的技术领域，尤其是涉及一种高速公路上水泥土路床的施工方法，其包括以下步骤：S1、清扫路基表面；S2、测量放样；S3、首层护土结构安装；S4、向首层护土结构内逐层填筑混合料并逐层摊铺、碾压；S5、洒水；S6、第二层护土结构安装：在首层护土结构的顶部安装第二层护土结构：S7、混合料摊铺、碾压：向第二层护土结构内逐层填筑混合料并逐层摊铺、碾压；S8、洒水：向碾压后的混合料表面均匀喷洒水，使混合料的含水量保持在合适范围内；S9、重复S6‑S8，直至路床厚度达到设计厚度；S10、边坡施工：施工路床两侧的边坡，本申请能够减少雨水冲刷而造成水泥土路床的松散流失，提高水泥土路床的强度，提高车辆行驶的安全性。
