Construction method for improving quality of large-particle-size gravel subbase
The invention belongs to the technical field of road quality control, and particularly relates to a construction method for improving the quality of a large-particle-size gravel subbase layer, which comprises the following steps: controlling the proportion of large-particle-size and fine aggregate to be large and the proportion of middle aggregate to be small; two-stage stirring is performed by adopting double stirring cylinders, the first-stage stirring cylinder stirs and mixes dry materials and water, and a discharging port is connected with a feeding port of the second-stage finished product stirring cylinder through a semi-finished product conveying belt; transporting the stirred and mixed base material from the mixing station to a construction site, and covering the base material with a covering in the transportation process; a paver is adopted for paving construction, and the paving speed and thickness of the paver are controlled in the paving process; rolling the flattened base material by adopting a process of primary pressing, re-pressing and final pressing, and carrying out quality control detection on a finished product after rolling; compared with the prior art, the method has the advantages that raw materials are controlled with higher requirements, more refined control is made technically, and the construction process is innovated, so that the quality of the graded broken stone subbase is remarkably improved on the whole.
本发明属于公路质量控制技术领域，具体涉及一种提高大粒径碎石底基层质量的施工方法，包括以下步骤：控制大粒径和细集料占比大，中间的占比小；采用双搅拌缸进行两级搅拌，一级搅拌缸搅拌混合干料和水，出料口通过半成品输送皮带与二级成品搅拌缸的进料口连接；将搅拌混合后的基料自拌和站运输至施工现场，运输过程中用覆盖物进行覆盖；采用摊铺机摊铺施工，摊铺过程中控制摊铺机的摊铺速度及厚度；采用初压‑‑复压‑‑终压的工艺对摊平后的基料进行碾压，碾压后对成品进行质控检测；本发明主要通过对原材料更出更高要求的控制、在技术上作出更精细化控制、在施工工艺上进行创新，使得级配碎石底基层质量总体上得到了显著提高。
