Description

Technical Field

[0001] The present invention relates to the technical field of tunnel repair material performance testing, and in particular to a tunnel repair material performance testing device and method in a stratum deformation and ion erosion coupling environment. Background Art

[0002] As an important part of modern urban public infrastructure, the urban power grid has an increasing demand for laying. Traditional ground overhead power grids are easily affected by weather and the lines are prone to aging, so urban cable tunnels have become an ideal choice. Cable tunnels have the advantages of large cable capacity, convenient maintenance and repair, and a complete abnormal monitoring system, and are widely used in urban power grid construction. However, due to the limitations of urban space, there are more and more construction projects adjacent to existing cable tunnels, which causes stress redistribution of underground soil layers and formation deformation. In addition, the corrosive ions in urban groundwater affect the service life performance of cable tunnels. Formation deformation can easily lead to instability of cable tunnel structures, such as formation settlement, landslides, and ground fissures. These deformations have a negative impact on the support structure and foundation stability of the tunnel, which in turn causes damage or deformation of the tunnel structure and affects the safety of the tunnel. At the same time, corrosive ions in groundwater, such as salt-containing, alkali-containing, chlorine-containing, and sulfate-containing ions, may cause tunnel erosion and damage, endangering the durability of the tunnel structure. Therefore, under the coupled environment of stratum deformation and groundwater corrosion, the tunnel structure will be subjected to greater stress and crack, and further structural water leakage will occur, causing corrosion or even destruction of the structure, affecting the safety of the cable tunnel structure and normal operation.

[0003] Traditional cable tunnel structures are made of concrete or brick materials, which are brittle materials with low tensile strength. Their working performance and durability are easily affected by long-term exposure to the coupled environment of stratum deformation and ion corrosion. Therefore, the research and development and performance research of tunnel repair materials suitable for use in the coupled environment of stratum deformation and ion corrosion is very important and needs to be solved urgently. It is very necessary to simulate the working environment of cable tunnels through experimental equipment for research. However, there is no performance test device and method for tunnel repair materials in complex environments. In view of the problems of the prior art, the present invention provides a performance test device and method for tunnel repair materials in a coupled environment of stratum deformation and ion corrosion.
