Semi-Integral Abutment Bridge is one of the bridge types that do not use Expansion Joints installed at the alternating part, and the integral abutment bridge It is a new concept of bridge type which is developed to compensate the limitation of application while making the most of advantages of the bridge.

Since the half-fold type alternating bridge is a bridge type in which the alternating expansion joint is not installed, maintenance and replacement are not necessary due to breakage of the joint expansion joint, so that it is more maintenance-friendly than general joint type bridge, Cost-effective economics are also excellent. In addition, there is no influence of the noise and impact generated when the vehicle is stretched or shrunk, and the continuity of the road is ensured, thereby ensuring the driving ability of the passing vehicle and the convenience of the highway user at the maximum.

A half-turn bridge is a bridge support installed between the upper structure and the alternation, minimizing the alternately transmitted load, thus inducing a fixed base role, such as a shift of a general joint bridge. In order to resist the binding force of the backfill material (passive earth pressure) caused by the temperature change, the alternating superstructure resists the binding force acting on the end diaphragm of the end portion, and the end partition wall is integrated with the superstructure And plays a beneficial role in the live load distribution that transfers to the alternating part.

This patent discloses a PSC I-type girder composed of an inner girder and an outer girder arranged on the outer side of an inner girder, wherein blocks having a constant width equal to or less than the height of the inner girder are integrally protruded and formed on both sides of the fulcrum of the inner girder , And the outer girder proposes a PSC I-type girder in which a block having a constant width is integrally protruded on one side of the flank of the fulcrum below the height of the outer girder. The PSC type I girder proposed by this patent can prevent the conduction accident of the PSC type I girder when the bridge is constructed mechanically by the reinforced concrete block, and when replacing the coils for common maintenance maintenance, It is possible to raise the bridge without an accident, and there is an advantage that it is easy to prevent the fall and to maintain the bridge.

However, the technology proposed by this patent requires a PSC I-type girder of a specific shape to be separately manufactured in order to prevent the falling of the cable. In addition, since the end bulkhead is constructed by putting in place, it takes a lot of time and manpower to place the reinforcing steel such as the connecting steel bar and the connecting slab and the reinforcing bar, and it takes a considerable amount of time until concrete pouring and curing. There is a growing problem. In addition, since the end bulkhead is installed after the bottom plate concrete is poured, the subsequent process is stopped until the bottom plate concrete is cured, air is stretched, and the construction time difference occurs between the bridge bottom plate and the connecting slab. There is a falling problem.
