Construction method of gobi rocky desert area framework compact type water-stable base layer
The invention relates to the technical field of civil engineering, in particular to a construction method of a gobi rocky desert area framework compact type water-stable base layer, and aims to solvethe problems that in the prior art, the construction quality of a cement-stabilized macadam base layer is difficult to guarantee, the construction cost is high, and the construction progress is slow,and the gobi rocky desert area framework compact type water-stable base layer construction method includes the following steps: S1, preparing materials of a cement stabilized gravel base layer; wherein the weight ratio of graded gravel to cement in the cement stabilized gravel base layer is 100: 4.7, the maximum dry density is 2.399 g/cm < 3 >, the optimal water content is 5.3%, and the grain sizeratio of the graded gravel is 27%: 29%: 16%: 28%; the grain size ratio of the graded gravel is 16-31.5 mm: 9.5-19 mm: 4.75-9.5 mm: 0-4.75 mm; S2, measuring and setting out; S3, paving a cement stabilized gravel base layer; S4, rolling the cement stabilized gravel base layer; S5, performing edge trimming and joint treatment; and S6, performing maintenance and finished product protection. The method can ensure that the cement stabilized gravel base layer in the gobi rocky desert area meets the requirement for excellent quality, and has the advantages of being simple, convenient, practical, lowin cost, capable of saving construction period and long in service life.
本申请涉及土木工程技术领域，具体涉及一种戈壁石漠区骨架密实型水稳基层施工方法，旨在解决相关技术中水泥稳定碎石基层的施工质量难以保证、施工成本高、施工进度慢的问题，包括以下步骤：S1、水泥稳定砂砾基层配料：水泥稳定砂砾基层中各组份重量比为级配砂砾:水泥＝100:4.7，最大干密度2.399g/cm3，最佳含水量为5.3％，其中，级配砂砾的粒径比例为16‑31.5mm:9.5‑19mm:4.75‑9.5mm:0‑4.75mm＝27％:29％:16％:28％；S2、测量放样；S3、摊铺水泥稳定砂砾基层；S4、碾压水泥稳定砂砾基层；S5、边缘修整和接缝处理；S6、养护及成品保护。本发明能保证戈壁石漠区水泥稳定砂砾基层达到质量优良的要求，具有方法简便实用，成本低，节约工期和使用寿命长的优点。
