AI Technical Summary

Technical Problem

Roads in high-water-level mining subsidence areas suffer from structural cracking, localized subsidence, and leakage failure during construction. Existing technologies struggle to achieve coordinated control of the seepage, deformation, and construction process quality.

Method used

The road adopts a flexible road structure, including a drainage base layer, an adaptive subbase layer, an integrated seepage prevention and drainage layer, a flexible stabilization layer, and a surface layer. Combined with digital twin technology and an intelligent monitoring system, it forms a multi-layered collaborative structure that can monitor and adapt to uneven settlement in the subsidence area in real time.

Benefits of technology

It enables rapid drainage and blocking of seepage channels in subsidence areas of mining areas with high groundwater levels, actively adapts to uneven settlement, improves the road's deformation adaptability, and ensures the long-term stability of the structure through intelligent construction and monitoring.

Abstract

The application discloses a flexible road suitable for a collapse area of a high water level mine area and a construction method thereof, and relates to the technical field of foundation treatment. The flexible road is sequentially provided with a drainage base layer, a self-adaptive cushion layer, an integrated anti-seepage and drainage layer, a flexible stable layer and a surface layer from bottom to top. The construction method divides a risk area through digital twinning, adopts foundation three-in-one control pre-disposal, is matched with factory prefabrication, on-site quick insertion installation and intelligent construction of unmanned aerial vehicles, AGVs and the like, and forms a whole-cycle closed loop through completion detection and intelligent monitoring. The application realizes three-dimensional seepage control and deformation self-adaptation, solves the problems of seepage and subsidence in the collapse area, is efficient and controllable in construction, and improves long-term stability of the road.
