摘要
通过对整个路段的探测,将巷道的位置和走向确定下来,采用合理布孔,将整个路基范围内的巷道全部先注砂后注浆,将巷道全部充满,从而保证路基的稳定性。
Through the detection on the whole road section,the location and direction of laneway are determined.Reasonable pore layout is adopted.Sand injection is first performed and grouting is then performed for the whole subgrade range,and the laneway is filled completely,thus guaranteeing the stability of subgrade.
