Therefore, the member manufactured under good quality control can be used.
Furthermore, as each concrete member, one in which prestress is introduced is used. Therefore, it is possible to expect sufficient strength while having a small cross section and being lightweight. The main members used in the method of the present invention are bridge piers, transverse lees and vertical lees.

In the construction method of the present invention, a structure in which a rail or a rail is integrally attached to the vertical grout 1 is used. That is, it is characterized by using prestressed grits with rails, which are integrally mounted with rails at the factory. Since the rails and the like are integrated with the vertical grove 1, the rails are simultaneously transported and erected by the transportation and erection work of the vertical gruel 1.
Further, since the railroad track and the vertical rail 1 are integrated, it is not necessary to separately construct a roadbed or the like, and at the same time the construction of the vertical rail 1 is completed, the railroad construction is completed.

This bridge pier 2 is also a factory-produced prestressing member, and therefore construction is extremely quick compared to the method of pouring and constructing concrete on site.

A crossing pad 3 is installed. Naturally, the cross-cuts 3 must be fixed integrally with the upper end of the pier 2. To do that, see Figure 2.
As shown in Fig. 4, fix the intersecting rebars with cast-in-place concrete, or tension the PC steel material that penetrates the crossbridge 3 and the pier 2 from the outside of the pier 2, or install the crossover 3 on top of the pier 2. It is possible to use a PC steel material exposed from the upper end of the pier 2 for tensioning the transverse lees 3 and various other fixing methods.

る。<C> Construction of the vertical grout 1 The vertical grout 1 is erected and fixed on the upper part of the transverse grout 3 fixed to the upper end of the pier 2 in this way. A rail or rail is directly fixed to the vertical grove 1 as described above. Therefore, by laying the vertical grits 1 on the upper part of the cross grates 3, the laying of rails is completed in one. After that, the transverse gruel 3 and the vertical gruel 1 are integrally and firmly fixed. At the time of erection, since one rail is fixed to one vertical grove 1, a set of tracks is completed by erection of two vertical grates 1 on the transverse grates 3 in parallel.

For that purpose, for example, the sound insulating material 4 is attached to the lower surface of the vertical grain 1. Further, a sound absorbing material 5 such as a foam material is filled between the vertical grout 1 and the vertical grout 1, and between the vertical grout 1 and the sound insulating material 4. When the above configuration is adopted, the sound generated by the vehicle traveling on the upper part of the vertical sill 1 is absorbed by the sound absorbing material 5 and further reflected by the surrounding sound insulating material 4 to prevent propagation to the surroundings. .

用できるものである。The construction method of the railway viaduct according to the present invention is as described above, so that the following effects can be obtained. <B> Use the vertical sluice 1 and rail already integrated. Therefore, slab construction is unnecessary, and further, a large amount of trackbeds mounted on the slab are unnecessary. Therefore, the dead load can be greatly reduced, and as a result, the horizontal inertial force at the time of the earthquake becomes small, so that the pier 2 cross section, foundation structure and other structures and sections can be made small, which is extremely economical. . <B> It is a method of assembling using the members manufactured in the factory. Therefore, the number of parts and members is small as compared with the method of forming a concrete form and pouring concrete on site, and the construction period can be significantly shortened. <C> Since the slab cast in place is not used, but the rails and the fixed grits are used, there is no need to support the slab formwork. Therefore, even when constructing on the upper part of the railway in use, it is possible to reduce the height of the supporting work and the formwork, and economical construction is possible. <D> The vertical grain 1 is independently connected to the horizontal grain 3. For this reason, the noise of vehicle running may be widely propagated from the space between the vertical groves 1 to the surroundings, which may be inconvenient in an urban area. Therefore, in the method of the present invention, the vertical grout 1 is surrounded by a material that blocks sound. Therefore, it is difficult for vehicle running noise to propagate around the viaduct and it can be used in a wide range.
