Description

[Detailed description of the invention] [Industrial field of application] This invention relates to precast concrete sheet piles used for seawalls, etc.

[Problem that the invention attempts to solve]

In recent years, a method has been adopted in which a pile is driven into the back of the sheet pile as an anchor, and the pile and the sheet pile are connected with substantially horizontal reinforcing bars to increase the earth pressure resistance of the sheet pile. It is desirable to provide a means to tie the reinforcing bars to the sheet piles in advance.

This idea was developed in response to such a method, and aims to facilitate the connection with piles by forming reinforcing plates that connect the reinforcing bars to the sheet piles.

[Means for solving problems]

In the present invention, the sheet pile is bent vertically on both sides and is formed continuously in the longitudinal direction, so that it has a U-shaped cross section, and a reinforcing plate is provided in the shape of a parallel plate integrally with the entire circumference of the inner wall surface of the sheet pile. The above problem is solved by forming reinforcing bars and having reinforcing bar insertion holes drilled in the reinforcing plate.

In this reinforcing bar insertion hole, the sheet pile and the pile are connected by a connecting reinforcing bar.

〔Example〕

The present invention will be explained below based on the drawings showing one embodiment.

This precast concrete sheet pile A (hereinafter referred to as sheet pile A) has a U-shaped cross section with both sides bent vertically, as shown in Figure 1, and the inner wall surface is between the opposing bent parts 1 and 1. A reinforcing plate 4 in the form of a parallel plate is formed integrally with the entire circumference of the reinforcing plate 2, and a reinforcing bar insertion hole 3 is perforated in the reinforcing plate 4 in the vertical direction.

A second reinforcing bar insertion hole 3 provided in this reinforcing plate 4
A connecting reinforcing bar 5 is inserted as shown in the figure, and the sheet pile A and the pile 6 are connected as shown in FIG. 3.

The pile 6 is driven into the ground in a direction perpendicular to the sheet pile A, and the connecting reinforcing bar 5 is tied to its head.

The sheet piles A and the piles 6 may be connected by inserting steel rods or bolts into the reinforcing bar insertion holes 3 and tying the connecting reinforcing bars 5 to both ends of the steel rods or bolts.

The reinforcing plates 4 are not limited to one level, but may be installed in several levels in parallel. In this case, a steel rod or the like is inserted between the reinforcing bar insertion holes 3, 3 of the opposing reinforcing plates 4, 4, and connecting reinforcing bars are inserted at both ends of the reinforcing plates 4. 5 is tied. Further, the reinforcing plate 4 may have only one reinforcing bar insertion hole 3.

The reinforcing plate 4 also has the function of reducing the overturning moment of the sheet pile A by filling the back surface of the sheet pile with soil.

[Effect of idea]

As described above, with this invention, the connecting reinforcing bars can be easily inserted into the insertion holes of the reinforcing plate, and the connecting reinforcing bars can be tied directly to the sheet piles at the site, making it easy to connect them to the piles. Also, since the sheet pile is integrated with the reinforcing plate, the bent portion can be reinforced and its thickness can be reduced.
