In railways, tracks are generally laid using trackbeds that use ballast for the trackbed, but in recent years, as trains have become faster and the number of trains passing has increased, the labor and expense of trackbed destruction and track maintenance work has increased, and in order to cope with this, Slab track was developed with the main purpose of making the track maintenance-free, and is already used in various places on Shinkansen and conventional lines.

According to the conventional technology described above, there are two types of track slabs, one is flat plate-shaped and the other is frame-shaped with an open center, as shown in the figure.The former has a track slab that fully supports the train load, so the load support efficiency is improved. It is wasteful, the manufacturing cost is high, and the amount of filler used is large, making it uneconomical. Furthermore, since the slab is flat, there are problems such as noise generated from the train or the contact portion between the rail and the wheels being reflected on the slab surface, resulting in large noise.
In the latter case, there are many parts of the filler exposed to the outside air, which causes problems in terms of strength, elasticity, and durability, so synthetic resin fillers are usually used, resulting in excessive material costs. There is.

According to the present invention described in detail above, the filling material is injected by arranging the injection bag directly below the rail of the track slab, thereby eliminating the need for constructing any formwork when injecting the filling material. This has the effect that the amount of filler used can be reduced. After injection, because of the mesh structure, some of the filler that seeps out of the injection bag gets buried in the unevenness of the subgrade concrete and track slab and hardens, increasing the integration of the injection bag with both structures and stabilizing the entire track. let Furthermore, the injection bag itself has the effect of reinforcing the filler, and also has the effect of facilitating construction because there is only one injection port for the filler.

In this method of constructing a slab track in which rails are laid on a track slab, the track slab is a frame-shaped track slab, and an injection bag that allows the filler to seep out and has air permeability is placed directly below the rail of the frame-shaped track slab. The frame-shaped track slab is supported at a certain height by injecting flexible filler into this injection bag, and the filler is filled between the locking protrusion and the frame-shaped track slab to form a concrete floor. A method for constructing a slab track characterized by integrating a plate and a frame-shaped track slab. 2. The method of constructing a slab track according to claim 1, characterized in that an injection port for the flexible filler is provided on one side of the injection bag, and irregularities are provided on the surfaces of the track slab and roadbed concrete that contact the injection bag.
