摘要
地铁隧道钢弹簧道床的渗漏点通常具有隐蔽性,难以通过常规方法发现和处理。本文通过多种方法,包括结构设计调研、分区排查、地质雷达检测和内窥镜检测等,准确定位钢弹簧道床的渗漏点,并分析其成因,提出治理方案(注浆)。实践表明,单一检测手段难以全面反映渗漏状态,地质雷达与内窥镜等多方法联用可有效互补,提升检测准确性,有助于实现精准注浆和结构病害的高效处置。
Leakage points in a subway tunnel steel spring track bed are typically concealed,making them difficult to detect and address with conventional methods.This article integrates various methods,including structural design research,sectional inspections,ground penetrating radar detection,and endoscopic examination,to accurately locate the leakage point of the steel spring track bed,analyze its causes,and propose the treatment plan(grouting).The practices show that single detection method is insufficient to fully characterize the leakage conditions.The combined application of ground penetrating radar and endoscopic detections can effectively complement each other,therefore enhance the accuracy of detection,and achieve accurate grouting and efficient treatment of structural diseases.
