Lifting and reinforcing method for shallow foundation of high-speed railway
The invention relates to the technical field of high-speed railway lifting and reinforcing, and provides a high-speed railway shallow foundation lifting and reinforcing method which comprises the steps that the lifting range is determined, and the range, needing to be lifted, of a high-speed railway is determined; according to the lifting range, executing the following steps: forming a first reinforcing body, and arranging the first reinforcing body below the high-speed railway foundation; a lifting body is formed, and the lifting body is arranged below the reinforcing area of the first reinforcing body for grouting, lifting and leveling; forming second reinforcing bodies, and arranging the second reinforcing bodies below the lifting body at intervals; and the two curtain walls penetrate through the first reinforcing body, the lifting body and the second reinforcing body from the two sides of the rail to form the two curtain walls. According to the scheme, the inclined cement reinforcement body is formed in the middle of the curtain wall, the purpose of reinforcing the foundation of the high-speed railway can be achieved while shallow lifting deviation correction of the high-speed railway is achieved, and the curtain wall has the advantages of being high in stability, short in construction period, low in cost and free of influence on normal operation of the high-speed railway.
本发明涉及高速铁路抬升加固技术领域，提供一种高速铁路浅层基础抬升加固方法，包括：确定抬升范围，确定高速铁路需要抬升的范围；根据所述抬升范围，执行：形成第一加固体，在高速铁路基础下方布置第一加固体；形成抬升体，在第一加固体的加固区以下布置抬升体进行注浆抬升调平；形成第二加固体，在抬升体下方间隔布置第二加固体；形成帷幕墙，在轨道两侧穿过第一加固体、抬升体以及第二加固体，形成两道帷幕墙。根据本发明的方案，在帷幕墙中间形成倾斜水泥增强体，能够在满足高速铁路浅层抬升纠偏的同时，也达到了高速铁路基础加固的目的，具有稳固性高、工期短、成本低、不影响高速铁路正常运行的特点。
