Construction method of high-fill steep fitting slope roadbed
The invention provides a construction method of a high-fill steep fitting slope roadbed. The construction method comprises the following steps: before construction, soaking bamboo ribs and bamboo splits in a mixed solution of water and boric acid; removing the earth surface; one end of each bamboo rib is inserted into undisturbed soil on one side of the steep fitting slope foundation pit, and the other end of each bamboo rib is exposed; a plurality of bamboo ribs are laid in the horizontal direction and sequentially inserted into the undisturbed soil; weaving the bamboo splits, the auxiliary bamboo reinforcements and the exposed parts of the bamboo reinforcements to form a bamboo reinforcement grating; the steps S3 to S5 are repeated on the other side of the steep fitting slope foundation pit, and the bamboo reinforcement grids arranged on the two sides of the steep fitting slope foundation pit are located on the same horizontal line; a geocell is laid between the bamboo reinforcement grids on the two sides of the steep fitting slope foundation pit, and the two ends of the geocell are connected with the bamboo reinforcement grids in a pressing mode respectively; s7, filling the roadbed layer by layer, and repeating the steps S3 to S7 when the height of the roadbed layer by layer is 4m, so as to complete the installation of the next bamboo reinforcement grating and the geocell; and S8, repeating the step S8, and sequentially backfilling the upper embankment, the lower roadbed, the upper roadbed and the pavement when the construction distance is 1.5 m left from the filled top surface.
本发明提出一种高填方陡贴坡路基施工方法,包括施工前将竹筋、竹篾浸渍于水与硼酸的混合溶液中;清除地表;将竹筋的一端插入陡贴坡基坑一侧的原状土中,竹筋的另一端外露;将多根竹筋沿水平方向铺设,依次插入原状土中;将竹篾、辅助竹筋与竹筋外露的部分进行编织,形成竹筋格栅;在陡贴坡基坑的另一侧重复步骤S3至S5,陡贴坡基坑两侧设置的竹筋格栅位于同一水平线;在陡贴坡基坑两侧的竹筋格栅之间铺设土工格室,土工格室的两端分别与竹筋格栅压接;分层填筑路基,当分层回填至4m高度时,重复步骤S3至S7,完成下一道竹筋格栅及土工格室的安装;重复步骤S8,直至施工距离填筑顶面剩余1.5m时依次回填上路堤、下路床、上路床、路面。
