| titleOfInvention | Shield tunnel instant quick-setting type synchronous grouting system and quick-setting agent capsule |
| abstract | The utility model discloses a shield tunnel instant quick-dissolving quick-setting type synchronous grouting system and an accelerator capsule, which comprises an accelerator capsule, a synchronous grouting pipeline of a shield machine and an additive grouting pipeline, the accelerator capsule is formed by encapsulating an accelerator with a water-soluble encapsulating material, the additive grouting pipeline is communicated with the synchronous grouting pipeline, the method comprises the steps of doping an accelerator capsule in synchronous grouting slurry of a synchronous grouting pipeline through an additive grouting pipeline, injecting the synchronous grouting slurry doped with the accelerator capsule into a space between a soil body and a pipe piece, dissolving a water-soluble material of the accelerator capsule, releasing an accelerator, reacting the accelerator with the synchronous grouting slurry, locally and rapidly generating a reinforced coagulation block, rapidly providing support between the soil body and the pipe piece by the local reinforced coagulation block, inhibiting buoyancy generated by a tunnel section which is not solidified by synchronous grouting, and controlling deformation of a tunnel pipe piece structure. |
