Roadbed rock ballast filling construction method
The invention relates to the technical field of roadbed construction, in particular to a roadbed rock ballast filling construction method. Comprising the following steps: surveying and setting out before construction; cleaning the earth surface; base treatment is conducted, specifically, foundation soil is rolled till the soft and elastic phenomenon occurs, and the compactness of the foundation soil at all positions is the same; performing primary rolling; foundation treatment is conducted, specifically, rock ballast is pressed into soft foundation soil through a compacting machine to be mixed with the soil, and a foundation is formed; the compaction degree is detected; measuring and setting out; rock ballast filling; and compacting. The rock ballast is pressed into the soft foundation soil through a compacting machine and mixed with the soil to form a foundation, the compaction degree can meet the design requirement, construction is fast and simple, and efficiency is improved; after rock ballast filling, through a rolling mode of combining initial pressing, re-pressing and final pressing, the principle of'slow first and then fast, and static first and then vibration 'is adopted, so that the rolling efficiency and the rolling quality are improved; after preliminary rolling, the compactness of each part of the foundation soil is roughly the same, then rock ballast is paved and compacted, and the forming quality of the foundation is high.
本发明涉及路基施工技术领域，具体为一种路基石渣填筑施工的方法；包括以下步骤：施工前测量放样；地表清理；基底处理，即将地基土碾压至出现软弹现象，并使得地基土在各处的密实度相同；初步碾压；地基处理，即使用压实机械将石渣压进松软的地基土内与土壤混合，形成地基；检测压实度；测量放样；石渣填筑；压实。通过压实机械将石渣压进松软的地基土内，与土壤混合后形成地基，压实度就可以达到设计要求，施工较快、简单，提高了效率；石渣填筑后，经初压、复压和终压组合的碾压方式，采用“先慢后快，先静后振”的原则，提高碾压效率，以及碾压质量；先经初步碾压后，使得地基土各处密实度大致相同，再摊铺、压实石渣，地基的形成质量较高。
