摘要
针对富水圆砾地质条件下,土体注浆加固效果较差、造价较高的问题,采用声纳渗流检测技术,通过测量地下水流速、流向、流量和渗透系数等数据,利用三维可视化图像确定渗漏通道指导施工,采取有针对性的防渗加固土体措施。同时结合土层特性,调整袖阀管注浆成分和灌浆长度,实现精准加固。
Targeting at problems of poor grouting reinforcement effect and high construction cost in water-rich round gravel stratum conditions,the sonar seepage detection technology is adopted.By measuring the groundwater flow velocity,direction,volume and the coefficient of permeability,3 D visualization image is used to guide the construction by determining the leakage channel,and targeted anti-seepage soil reinforcement measures are adopted.At the same time,combined with the characteristics of soil layer,the sleeve valve pipe grouting composition and grouting length are adjusted to achieve accurate reinforcement.
