Abstract The patent of the utility model relates to a special U shaped steel support of city subway construction. This supporting structure mainly includes an arching for the clamping cable that connects and the connecting bolt on upper portion, the support leg of vertical direction, an arching of lower part. Wherein go up an arching and choose U shaped steel for use, can play certain pressure effect that lets, the support leg and the bottom suspension arching of lower part adopt the mining I -steel of 11#, have the ability of resisting surrouding rock deformation very by force, each part is connected through clamping cable to the three bolt of equidistance installation above that prevents to become flexible, has further improved the supporting intensity of support. This support simple structure, the installation of being convenient for, very big improvement the construction speed of city subway, have good engineering application and worth. This structure extensively is applicable to the tunnel engineering that city s
