Roadbed reinforcing method
The invention provides a roadbed reinforcing method. The roadbed reinforcing method comprises the steps that screen tubes are driven into a preset area from one side of a roadbed along a preset path;grouting pipes stretch into first positions in the screen pipes, and grouting is carried out at first grouting pressure; and the grouting pipes stretch into second positions in the screen pipes, and grouting is carried out at second grouting pressure, wherein the distance from the first positions to the side of the roadbed is larger than the distance from the second positions to the side of the roadbed. According to the roadbed reinforcing method, segmented grouting from inside to outside can be achieved, and different grouting pressures can be adopted for grouting in different areas so that the grouting amounts corresponding to the requirements of the different areas can be obtained in the different areas, the situation that rod ballasts are hardened due to the fact that a large amount ofslurry flows into areas with low pressure intensity such as the rods ballasts is effectively avoided, moreover, the situation that an area with high pressure intensity cannot obtain enough grouting amount is effectively avoided, and the grouting uniformity is effectively guaranteed.
本申请提供一种路基加固方法，包括：将花管沿预设路径从所述路基的一侧打入至预设区域；将注浆管伸入至所述花管内的第一位置，以第一注浆压力进行注浆；将所述注浆管伸入至所述花管内的第二位置，以第二注浆压力进行注浆；其中，所述第一位置到所述路基的所述一侧的距离大于所述第二位置到所述路基的所述一侧的距离。这种路基加固方法可以实现由内到外分段注浆，可以在不同的区域采用不同的注浆压力进行注浆，使不同的区域均可以得到与其需求对应的注浆量，有效避免了浆料大量流入道砟等压强较低的区域而导致道砟板结，并且也有效避免了压强较高的区域无法得到足够的注浆量，有效保障了注浆的均匀性。
