Two-way adjusting device for ballastless track high-speed railway bed deformation, using method and construction method
The invention discloses a two-way adjusting device for ballastless track high-speed railway bed deformation, a using method and a construction method. The device comprises floral tubes distributed atintervals in a longitudinal direction of a line, the floral tubes are obliquely arranged downwards from the two sides of a foundation bed to the center line, the lower ends of the floral tubes are located at the bottom of the foundation bed, grouting openings of the floral tubes are detachably connected with sealing covers, and displacement sensors are further arranged in the foundation bed. By the adoption of the device, pressure grouting can be conducted through the pre-buried floral tubes to improve settling deformation; the embedded floral tubes can be pulled out of the foundation bed to form pressure relief holes, thereby reducing upwarp deformation, effectively saving later roadbed settlement or arching renovation and maintenance cost, reducing operation risks caused by roadbed deformation, and thus effectively guaranteeing smoothness, stability and safety of line operation; and deformation adjustment is carried out in the operation period, the construction becomes convenient andthe interference to high-speed rail operation is low. The two-way adjusting device is widely applied to various roadbeds, and has great popularization significance.
本发明公开了一种无砟轨道高速铁路路基基床变形双向调节装置、使用方法及施工方法，装置包含花管，所述花管沿线路纵向间隔分布，所述花管分别沿基床两侧向中线倾斜向下设置，所述花管的低端位于所述基床的底部，所述花管的注浆口可拆卸连接有密封盖，所述基床中还设有位移传感器。采用本装置能够通过预埋的花管进行压力注浆，改善沉降变形，又能够通过将预埋花管从基床中拔出形成的卸压孔，减小上拱变形，有效节约后期路基沉降或上拱的整治维护费用，降低路基变形带来的运营风险，从而有效保证线路运行的平顺性、稳定性和安全性，且在运营期间进行变形调节，施工便捷，对高铁运营干扰小，广泛适用于各种类型的路基，具有重大推广意义。
