Although precast slabs / precast slabs are pre-fabricated and then precast slabs are laid on the girders by ground cranes, etc., the use of ground cranes increases construction costs. For example, it often happens that traffic must be controlled for a hypothesis. And especially when the pier is very high, it is difficult to mount using a ground crane.

In addition, it is possible to form a bridge by sequentially pushing the precast slab sequentially on the girder prefabricated on the pier by using an extrusion means such as an extrusion jack and manufactured from the rear of the shift proposed in Patent Document 1.
