Tunnel lining structure with combined action of high-strength pre-pressing anchor rods and fluid inclusions

Abstract

The invention relates to a tunnel lining structure with a combined action of high-strength pre-pressing anchors rod and fluid inclusions. The tunnel lining structure comprises the fluid inclusions, the high-strength pre-pressing anchor rods and reinforced concrete linings which are in contact with tunnel surrounding rock, wherein the fluid inclusions are fixed around the tunnel surrounding rock with the high-strength pre-pressing anchor rods and the reinforced concrete linings, a pressure relief valve is arranged at one side of each fluid inclusion, and the fluid inclusions are provided with connection interfaces linked with other inclusions; the sides, facing the tunnel, of the liquid inclusions are provided with the reinforced concrete lininsg, the reinforced concrete linings are fixed by the high-strength pre-pressing anchor rods, and every two adjacent liquid inclusions are detachably assembled and connected through connecting interfaces arranged at the side edges. The tunnel lining structure can solve the problem that in the prior art, the possibility of local deformation of the tunnel is greatly reduced while the requirements of tunnel lining are met, and it is guaranteed that a support structure can not to be deformed due to local large surrounding rock stress.

Description

technical field [0001] The invention relates to the field of lining devices for tunnel engineering, in particular to a tunnel lining structure in which high-strength preloaded anchor rods and fluid inclusions act together. Background technique [0002] With the construction of national infrastructure and the acceleration of the pace of life of the people, shortening the traffic time between regions has become a social consensus. The planning and construction of multiple high-speed rail lines also means strict requirements for the quality of tunnel engineering and the limitation of construction period. reduce. New conjoined fluid inclusions have become an important component in tunnel engineering. It is not only conducive to controlling the quality of the project from the source, but also can greatly shorten the construction period, and can also reduce the losses caused by engineering accidents. [0003] Tunnel engineering construction has become an important part of nation...

AI Technical Summary

Problems solved by technology

If the surrounding rock collapses during the construction process, it will lead to the collapse of a large area in the tunnel, causing serious loss of personnel and property, and when the tunnel construction encounters water gushing or water leakage, it will directly affect the maintenance cycle of the concrete and delay the progress of the project
