High-speed railway expansive rock soil deep cutting structure and construction method thereof
The invention discloses a high-speed railway expansive rock soil deep cutting structure and a construction method thereof. The structure comprises: a plurality of reinforcing support piles, wherein the reinforcing support piles are divided into two rows and are symmetrically arranged at a deep cutting slope toe, and each row of reinforcing support piles are arranged at intervals; supporting crossbeams which is arranged on a foundation between the two reinforcing supporting piles which are symmetrically arranged; a buffer layer which is arranged on the foundation at the bottoms of the supporting cross beams; a waterproof layer which is arranged on a foundation between every two adjacent supporting cross beams; and a bearing plate which is connected to the tops of the supporting cross beamsand connected to the reinforcing supporting piles, wherein the bearing plate is used for arranging a rail structure. The technical problem of upwarp deformation of the high-speed railway caused by expansive rock and soil is effectively solved, and the high-speed railway expansive rock soil deep cutting structure has the characteristics of expansive rock and soil stability, controllable upwarp deformation, convenience in construction, economy, environmental protection, convenience in popularization and application and the like.
本发明公开了一种高速铁路膨胀岩土深路堑结构及构筑方法，该结构包括若干个加固支撑桩，分成两排对称设置在深路堑坡脚，每排所述加固支撑桩间隔设置；支撑横梁，设置在对称设置的两个所述加固支撑桩之间的地基上；缓冲层，设置在所述支撑横梁底部的地基上；防水层，设置在相邻两个所述支撑横梁之间的地基上；承载板，连接于所述支撑横梁顶部，并连接于所述加固支撑桩，所述承载板用于设置轨道结构。有效解决了膨胀岩土造成高速铁路产生上拱变形的技术难题，具有膨胀岩土稳定性和上拱变形可控、施工方便、经济、环保和利于推广应用等特点。
