Description

[Detailed Description of the Invention] The present invention relates to a protector for a long submarine body that protects a long submarine body such as a submarine cable or water pipe installed on the seabed.

When a conventional protection body of this type is used to protect a long body laid on a slope on the seabed, the weight of the body accumulates below the slope, causing damage to the long body. There were drawbacks.

Furthermore, the conventional protective body has the disadvantage that the impact force applied to the protective body for some reason is directly transmitted to the elongated body.

The purpose of this invention is to be able to fix the protection body to the long seabed body, to prevent damage to the long seabed body at the fixing part, and to prevent the long seabed body from being damaged even if an impact force is applied to the protection body. An object of the present invention is to provide a protector for an elongated submarine body that can protect an elongated body from impact force.

A protection body for an elongated seabed body according to the present invention includes a protection body having a through-hole for the elongated seabed body in the front-rear direction, and a through-hole for the elongated seabed body communicating with the through-hole, and having one end side of the protection body. a connector made of a rubber elastic body fixed to the body; a connector fitting locking hole provided on the other end side of the protective body communicating with the through hole; and a connector fitting locking hole that is fitted into the connector fitting locking hole. longitudinally compressible in a portion of the through hole between the connector and the connector fitting locking hole within the protective body so that it can be pushed and compressed by another connector to be fitted; The present invention is characterized in that it has a compression sleeve for fixing a protective body made of a rubber elastic body, which is disposed in a state of .

Embodiments of the present invention will be described in detail below with reference to the drawings.

Such a connector 7 is made of a material having rubber elasticity, such as rubber or plastic, and has protrusions on its outer surface to ensure good locking.

At the rear of the protection body 2, a connector fitting locking hole 9 is connected to the through hole 3.
This hole 9 is also divided into upper and lower halves by the dividing surface of the protective body 2.

A compression sleeve 1 for fixing the protector is provided in the through hole 3 between the connector γ and the connector fitting locking hole 9 in the protector body 2.
0 is fitted.

The sleeve 10 also has a split surface 11 formed on the same surface as the protective body 2.

It is divided into upper and lower two divided bodies 10A and 10B, the front ends of each are fixed to the divided bodies 7A and γB of the connector γ, and the rear end of each is compressed in the length direction in the through hole 3. Compression movement is possible in the length direction.

Such a compression sleeve 10 is made of a rubber elastic material such as rubber or plastic, and is processed so that a compressed portion A and a swollen portion are formed when compressive force is applied from the longitudinal direction. ing.

A collar 12 made of metal or hard plastic is slidably disposed in a portion of the through hole 3 behind the sleeve 10.
This collar is also provided with a splitting surface 13 at the splitting surface 4 of the protective body 2, and is divided into two splitting bodies 12A and 12B, which are respectively divided into two splitting bodies 10A and 12B of the sleeve 10, respectively.
It is fixed at 10B.

Such protectors 1 are each installed around the long submarine body 13, and after installation, the connector 7 of the subsequent protector 1 is pushed into the connector fitting locking hole 9 of the previous protector 1 and fitted. Then, the front and rear protectors 1 are connected.

By pushing the connector 7 in this way, the compression sleeve 10 for fixing the protector 1 of each protector 1 is compressed in the length direction as shown in FIG. The body 1 is fixed to a long seabed body 13.

Therefore, the load of each protector 1 is applied to the long seabed body 13 as a distributed load, and even when the protector 1 is installed on a slope or from a laying ship, the load of the protector 1 is not concentrated downward. It can be prevented.

A gap d is provided between the front and rear protectors 1 by the step portion of the connector 7, and this gap is used to allow the protected elongated submarine body to bend to an allowable bending radius.

Figures 4 and 5 show divided bodies 2A and 2B of each protective body 2.
An example of a connecting tool 5 for interconnecting is shown.

This connector 5 has a female member 14 embedded in the lower surface of one of the divided bodies 2A of the protective main body 2, and a dovetail groove-shaped male member locking hole 15 is provided in the lower surface of this member 14. This hole 15
A wedge member 16 is provided inside to project downward from the upper surface.

A male member 17 made of a rubber elastic body whose lower part is embedded in the other divided body 2B is protruded from the upper surface of the other divided body 2B.

A notch 18 into which the wedge member 16 is inserted is formed in the upper part of the male member 11.

Such a connecting tool 5 is constructed by abutting the divided bodies 2A and 2B at the slit surfaces 4 and inserting the male member 1T into the locking hole 15 of the female member 14.
When fitted, the wedge member 16 on the female member 14 side is pushed into the notch 18 of the male member 11, the tip of the male member 15 is pushed open into two prongs, and the male member 17 is inserted into the locking hole 15 of the female member 14. are locked, and both divided bodies 2A and 2B are connected to each other.

Therefore, it is possible to easily attach the protective body 1 to the long submarine body.

In the above embodiment, the present invention is applied to a protector having a protector body made of concrete, but the present invention is not limited to this. For example, the protector body is made of metal such as cast iron or plastic. This can be similarly applied to a protective body with a protective body etc.

Further, although the protective body in the above embodiment has an oval cross-sectional shape, it is of course possible to have a circular cross-sectional shape.

Further, the protective body may be shaped like a basket.

As explained above, the submarine long object protector of the present invention has a compression sleeve for fixing the protector built into the protection main body,
By compressing this compression sleeve in the length direction within the through hole in the protection body, the protection body is fixed to the long submarine body. When protecting a seabed, each protector is individually fixed to a long seabed body.

It will be.

Therefore, the weight of each protector will be applied to the long seabed body as a distributed load, and even if the long seabed body is installed on a slope of the seabed or when it is laid from a laying ship, the load on each protector will be applied as a distributed load. can be prevented from concentrating on the lower part of the long seabed body, and can prevent the long seabed body from being cut by large tension.

In addition, this compression sleeve is compressed by inserting a connector of another protector into the protector in which it is built and connecting it, and while the protector is connected. Since medium compression continues, handling is easy.

Moreover, even if compression is applied in this manner, there is no risk of damaging the elongated seabed body since the compression sleeve is made of a rubber elastic body.

Furthermore, according to this protector, even if an impact force is applied to the protector, it is applied to the long seabed body through the compression sleeve made of a rubber elastic body and the connector, so the impact force is alleviated and the long seabed body can be effectively protected from impact.

Furthermore, according to the protector of the present invention, since the connector made of the rubber elastic body can be bent, the long submarine body with the protector can be bent to an allowable bending radius.
