Pavement crack grouting construction parameter selection method
The invention relates to the technical field of road engineering pavement maintenance, in particular to a pavement crack grouting construction parameter selection method which comprises the following steps: establishing a pavement structure model according to the working condition of a grouting road section; setting a grouting diffusion control equation in the simulation software, and inputting parameters of the control equation; the grouting process of the pavement structure model is simulated in simulation software, and a grouting diffusion radius-grouting time curve graph is output; according to different grouting pressures and the road surface arching pressure, the grouting pressure lower than the curve with the maximum grouting diffusion rate in the road surface arching pressure is determined; and according to the grouting diffusion radius-grouting time curve graph, the numerical value when the grouting diffusion radius tends to be stable is determined, and the grouting hole pitch is determined according to the numerical value. According to the arrangement of the mode, compared with the prior art, selection of grouting parameters is not based on engineering experience any more, reasonable selection is carried out according to the condition of a construction site, and then the grouting efficiency and the pavement repairing effect are improved.
本发明涉及道路工程路面养护技术领域，尤其涉及一种路面裂缝注浆施工参数选取方法，该方法包括以下步骤：根据注浆路段工况建立路面结构模型；在仿真软件中设定注浆扩散控制方程，并输入控制方程的各参数；在仿真软件中模拟所述路面结构模型的注浆过程，并输出注浆扩散半径‑注浆时间曲线图；根据不同注浆压力以及路面起拱压力，确定低于路面起拱压力中注浆扩散速率最大的曲线的注浆压力；根据注浆扩散半径‑注浆时间曲线图，确定注浆扩散半径趋于平稳时的数值，并根据该数值确定注浆孔间距。通过上述方式的设置，与现有技术相比，注浆参数的选取不再依据工程经验，而是根据施工现场情况进行合理选择，进而提高了注浆的效率和路面修复效果。
