More Information
Summary:The invention discloses a tunnel structure for subway shield intervals and a method for reinforcing strata. The tunnel structure for allowing the subway shield intervals to cross rivers underneath comprises multiplayer linings and grouting pipes. Reinforcing layers are formed in the strata by the grouting pipes. The method for reinforcing the strata for allowing the subway shield intervals to laterally cross viaducts includes arranging the deep grouting pipes and the reinforcing layers. The tunnel structure for allowing the subway shield intervals to cross the rivers underneath comprises the multiplayer linings, the grouting pipes and the reinforcing layers. Structures for reinforcing the strata for allowing the subway shield intervals to laterally cross the viaducts comprise the deep grouting pipes and the reinforcing layers. The tunnel structure and the method have the advantages that the bearing capacity of the subway shield intervals can be improved, influence of underneath crossing tunnel construction on
