Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a protective cover for protecting a tie rope used when constructing a quay, for example.

[0002]

[Prior art]

 Conventionally, for example, when constructing a quay, etc., a tie rope is stretched between the retaining wall made of piles and columns and the earth retaining sheet pile wall to maintain the standing state of the sheet pile wall while forming between them. It is constructed by laying rubble stones such as split stones in the space, and then placing concrete.

[0003]

[Problems to be solved by the device]

 However, since the tie rope is simply a wire covered with a synthetic resin covering material, the covering material may come into contact with the rubble when laying it or when laying rubble after the laying, and There was the inconvenience of being damaged.

When the coating material is damaged and cracks are generated in this way, the wire is corroded and the corrosion of the sheet pile wall cannot be maintained for a long period of time. It had a point.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a protective cover that can reliably protect a tie rope and that can be easily attached. And

[0006]

[Means for Solving the Problems]

 That is, the means adopted by the present invention to solve the above-mentioned problems is that a slit 4 is formed in a longitudinal direction in a flexible cylindrical cover body 1 and is fitted onto a tie rope 5 through the slit 4. It is configured so that it can be worn.

Further, as in claim 2, a plurality of convex portions 3 are formed in the cover body 1 at predetermined intervals in the circumferential direction, or the cover body 1 is fitted onto the tie rope 5 as in claim 3. It is also possible to include the attached tubular portion 2 and a plurality of hollow convex portions 3 formed on the outer peripheral surface of the tubular portion 2 at predetermined intervals in the circumferential direction.

Therefore, in the protective cover having the above-mentioned specific features of the invention, the slit 4 of the cover body 1 is expanded with the edges of the cover body 1 forming the slits 4 separated from each other. The tie rope 5 is inserted from the end, but after the insertion, the edges approach each other and the diameter of the cover body 1 is reduced, so that the tie rope 5 is externally fitted.

[0009]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a flexible protective cover body made of synthetic resin such as polyethylene. The protective cover body 1 has a cylindrical tubular portion 2 and a tubular portion 2. And a convex portion 3 having a hollow mountain shape and provided in the circumferential direction so as to project at a predetermined interval on the outer peripheral surface of the.

Reference numeral 4 denotes a slit formed in the cover body 1 along the longitudinal direction. The slit 4 is formed so that the slit 4 can be expanded / contracted and externally fitted to a tie rope 5 described later. Both end edges 1a are configured to be able to come into contact with and separate from each other. The inner diameter of the cover body 1 is set equal to or smaller than the outer diameter of the tie rope 5.

The present embodiment has the above-described specific items, and a case of constructing a quay using this will be described next.

First, as shown in FIG. 2A, the sheet pile wall 6 is erected at a predetermined position on the sea side A of the harbor, and the retaining wall 7 composed of piles and columns is arranged on the land side B so as to face it. However, the foundation D is installed in the space C formed between the retaining wall 7 and the sheet pile wall 6.

Next, one end of the tie rope 5 is fixed to the sheet pile wall 6 and the other end is fixed to the retaining wall 7 and stretched. As shown in FIG. 2B, such a tie rope 5 is obtained by coating a core material 8 made of a wire or the like with a covering material 9 made of a synthetic resin such as polyethylene. A plurality of tie ropes 5 have a predetermined interval. Is installed between the sheet pile wall 6 and the retaining wall 7.

After that, the protective cover 10 is attached to the tie rope 5. In this case, for example, a jig is used to separate both end edges 1a of the cover main body 1 from each other to expand the diameter, and Insert Tie Rope 5 from 4. After the insertion, the both end edges 1a come close to each other, the diameter of the cover body 1 is reduced, and the cover body 1 is fitted onto the tie rope 5.

In this way, the plurality of protective covers 10 are attached over the entire tie rope 5.

Since the protective cover 10 is made of flexible synthetic resin and the convex portion 3 is formed in a hollow shape, it is lightweight and the diameter of the cover body 1 can be easily expanded. Therefore, there is an advantage that a series of mounting work can be efficiently performed without imposing a burden on the worker.

After that, a rubble made of split stones etc. is laid on the foundation D, but the tie rope 5 is damaged by the rubble because the protective cover 10 is externally fitted to the tie rope 5. As a result, the sheet pile wall 6 is properly protected for a long period of time, and the standing state of the sheet pile wall 6 is reliably and firmly maintained.

The protective cover 10 in the above-described embodiment has a cylindrical cover main body 1 and a hollow mountain shape projecting in the circumferential direction at a predetermined interval on the outer peripheral surface of the cover main body 1. Since it is composed of the convex portion 3, it has an advantage that it can sufficiently secure its own strength and can reliably protect the tie rope 5, but for example, when laying rubble, its impact is not applied to the tie rope 5 so much. In such a case, as shown in FIG. 3, the bottom wall of the convex portion 3 in the above embodiment is omitted, and the cover main body 1 is configured so that the convex portion 3 extends in the tubular portion 2. However, the tie rope 5 can be well protected in this case as well.

Further, the cover body 1 does not necessarily need to be provided with the convex portion 3, and may be omitted.

Further, the width of the slit 4 can be appropriately changed according to the outer diameter of the tie rope 5, and its specific size is not important. The slit 4 referred to in the present invention means a cut formed by cutting the cover body 1 in the longitudinal direction.

Further, the tie rope 5 is used not only for constructing the quay as in the above-described embodiment but also for various purposes, and the protection cover 10 according to the present invention is widely applicable for protecting the tie rope 5. is there.

In addition, the material and the like of the protective cover 10 can be arbitrarily changed within the scope intended by the present invention.

[0024]

[Effect of the invention]

 As described above, according to the present invention, since the slit is formed in the longitudinal direction in the flexible cylindrical cover body and the slit can be externally fitted to the tie rope through the slit, By expanding and contracting the slit, it is possible to easily fit the tie rope on the outside, and thus a particular effect that a series of mounting work can be efficiently performed without burdening the operator is obtained.

Further, since the tie rope is appropriately and surely protected from the external impact by the protective cover, it is possible to prevent the tie rope from being damaged and to exert its function for a long period of time.

Further, when the convex portion is provided on the cover main body as in claim 2 or 3, the strength of the convex portion itself is improved, so that there is a peculiar effect of exhibiting a better protective function. .
