This prefabricated part is in the form of a hollow beam constituted by a tubular wall 23, which defines a central hole 20 covering the head 11 of the sheet pile 1 located above a flat surface 40. The prefabricated part 2 is used to construct a so-called abutment of a bridge. The abutment 30 supports the end 30 of the beam 3 including the bridge floor B. Therefore, the height of the flat surface 40 is adjusted according to the combined height of the prefabricated component 2 and the bridge floor B so that the upper surface 31 of the bridge floor B has a desired height.

However, in general, abutments are supported by at least two piles or sections 1,1 spaced apart from each other. In this case, the prefabricated component 2 can have two holes 20 that respectively engage the heads of one pile 1, or one elongated hole that covers the two piles 1, 1 at the same time. The prefabricated part 2 comprises two lateral walls 23 perpendicular to the longitudinal axis xx of the bridge floor B,

The integration studs 52 are inserted into the concrete D when the plate 5 is placed, ensuring in-situ joining of the plates after solidification of the concrete. A plurality of evacuation openings 54 are formed in the plate 5 to facilitate a slight sinking of the plate 5.

After solidification, the prefabricated component 2 is the upper part 11 of the sheet pile 1, 1.
It forms a transverse beam that is embedded and bonded on top. The upper surface of this transverse beam is composed of a plate 5 having a precisely adjusted height before solidification of the concrete D. The transverse beam 2 is further reinforced by a reinforcing cage 25 arranged in the central hole 20 between the two sheet piles 1, 1. As described above, the prefabricated component 2 forms an abutment supporting the end portion 30 of the bridge floor B. The bridge floor B can be composed of, for example, two metal vertical members 3 connected to each other by a plurality of horizontal beams, and the metal vertical members 3 support the assembled floor 32.

You can understand that. That is, the abutment 2 rigidly embedded and joined to the upper portions 11 of the sheet piles 1 and 1 can be maintained in an elevated state in an upward direction. It will be understood that the present invention is not limited to the above-mentioned embodiments, and modifications can be made without departing from the scope of the claims.

The member is used to maintain the desired height. When the prefabricated parts are embedded and joined, and after the solidification of concrete, the support member and the form are removed, the prefabricated parts are fixed and maintained on the heads of the piles. Although the present invention has been described above with reference to the support abutment at the end of the bridge floor B, an intermediate bridge pier can be constructed in a similar manner. In this case, the two lateral walls 23, 23 of the caisson beam 2 are at the same height.
