JPS6011980Y2 - Cover fitting with filler flow holes - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a tool for installing a corrosion-resistant cover.

As is well known, sheet piles are used for bank protection construction and the like, and are broadly divided into types in which multiple steel pipes are driven into the seabed and connected with joints, and bellows-shaped sheet piles.

In addition, there are two ways to protect steel pipe sheet piles from corrosion: one is to remove a portion of the joint and cover each steel pipe with a cylindrical cover, and the other is to install a continuous cover along one side of the sheet pile, as shown in Figure 1. There is.

The latter is more advantageous in terms of construction time and cost, but
As can be seen from FIG. 1, the space between the covers is partitioned at the joint, so filler must be injected into each area.

The present invention was devised to solve this problem, and is characterized by providing flow holes for the filler in the partition wall.

Embodiments will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a perspective view showing how the corrosion protection cover is installed near the joint.

A pipe-shaped guide 4 is welded to the joint 2, and its length is approximately equal to the corrosion-resistant cover 3.

Further, a slit 5 is formed on the outside of the guide 4 over the entire length.

On the other hand, the corrosion-resistant cover 3 has a T-shaped cross section and is connected to each other by means of fittings 6, and as a whole constitutes one continuous surface as shown in FIG.

As can be seen in FIG. 2, the end faces of each cover 3.3 are clamped by means 6 and then fixed with bolts.

For attaching the cover, the tip of the tool 6 is swollen, and this portion 7 is inserted into the guide 4 from above.

Therefore, the attachment tool 6 not only connects the covers together, but also serves to hold the cover 3 in place.

As shown in FIG. 3, a plurality of holes 8° are provided in the web wall 6a of the mounting device 6. As shown in FIG.

This allows the filler injected at one location to spread to all parts through these holes.

Therefore, various shapes and numbers of the flow holes 8, 8, .

Since it is necessary to partition both ends of the steel pipe sheet pile, it goes without saying that holes are not provided in this web wall.

Although not shown, the bottom of the corrosion-resistant cover around the steel pipe is curved inward and in contact with the steel pipe through a seal, and the bottom near the joint 2 has a cover as shown by imaginary line 9 in Fig. 2. Since it is sealed, there is no risk of the filler leaking.

Since various types of cover mounting tools can be considered other than the T-shape shown in the figure, it should be understood that the key point of the present invention lies in the perforated partition wall.

Therefore, it is clear that the present invention can be used not only for the steel pipe sheet piles shown in the embodiments, but also for bellows-shaped sheet piles.

As described above, according to the present invention, there is an advantage that the filler can be injected at one location.
