Construction method of three-way geogrid composite gravel pile roadbed
The invention provides a construction method of a three-way geogrid composite gravel pile roadbed, which comprises the following steps: detecting and cleaning a lower bearing layer: detecting the replacement construction quality of a shallow layer of the roadbed, and paving three-way geogrids after the replacement construction quality is detected to be qualified: fixing a group of three-way geogrids in advance, and then paving the three-way geogrids along the side edges of the fixed three-way geogrids; the unfixed three-way geogrids are driven by the traction assembly to be unfolded and flatly laid, and the two sets of three-way geogrids are kept to be free of gaps and dislocation. Fixing the geogrids: inserting four corners of the adjacent three-way geogrids into the ground through fixing pieces, and then splicing and fixing the adjacent three-way geogrids with the three-way geogrids on the two sides. Compared with the prior art, the unfixed three-way geogrid is pulled to be flatly laid and unfolded along the side edge of the fixed three-way geogrid through the traction assembly, the subsequent fixing work is completed, the unfixed three-way geogrid is guided and limited in the process, and the situation that a large gap exists between the unfixed three-way geogrid and the fixed three-way geogrid due to dislocation movement of the unfixed three-way geogrid is prevented; and the tiling efficiency is improved.
本发明提供一种三向土工格栅复合碎石桩路基的施工方法，检测、清理下承层：对路基浅层换填施工质量进行检测，检测合格后铺设三向土工格栅：预先固定好一组三向土工格栅，随后沿已固定三向土工格栅的侧边，通过牵引组件带动未固定三向土工格栅展开平铺，保持两组三向土工格栅没有间隙，也没有错位；固定土工格栅：相邻的三向土工格栅在四角处通过固定件插入地下后与两侧三向土工格栅拼接固定。相对于现有技术，本发明通过牵引组件将未固定三向土工格栅牵沿着已固定三向土工格栅的侧边平铺展开，并完成后续的固定工作，过程中对未固定三向土工格栅导向和限位，防止其错位移动导致两者之间存在较大的间隙，提高平铺的效率。
