The utility model provides a rail mounting structure capable of adjusting the height in a large range, and the rail mounting structure is an important component of urban rail transit and an important foundation of train operation. In order to adapt to the characteristic of large settlement deformation of a soft foundation in urban rail transit construction, a bottom plate is pre-buried at the top of a ballast bed foundation, pre-buried nuts and pre-buried anchor bolts are connected with an upper fastener system, and a bottom plate heightening base plate is arranged at the upper part of the pre-buried bottom plate; and unlimited height adjustment of the steel rail except the allowable range of the upper fastener system is realized. On one hand, the device can adapt to differential settlement of a ballast bed foundation, the height adjusting capacity is high, and the foundation treatment cost can be reduced; and on the other hand, the difficulty of rail installation construction can be reduced by embedding the
