Description

The present invention relates to a pipe protector. One more specific example relates to water pipe protection.

  Patent Literature 1 discloses a technique of a heat insulating sheet for a water pipe.

JP 2016-095004 A

  However, the method described in Patent Document 1 cannot prevent the penetration of a chemical substance into a water pipe.

  An object of the present invention is to provide a pipe protector that can prevent a chemical substance from penetrating into a pipe.

  A pipe protector according to a first aspect of the present invention includes a tubular chemical protection sleeve for preventing a chemical substance from reaching a pipe buried underground, and a chemical protection sleeve that covers the outside of the chemical protection sleeve. And a physical protective sleeve for preventing physical damage to the device.

  Preferably, a film layer covering the outside of the physical protective sleeve and having information about the tube printed thereon.

  Preferably, the physical protection sleeve is formed by knitting a plurality of thread-like structural materials, or is formed of a foam material.

  Preferably, said chemical protection sleeve is formed of nylon.

  The pipe protector according to the present invention makes it possible to provide a pipe protector capable of preventing a chemical substance from penetrating into a pipe.

It is an explanatory view of a pipe protector according to a first embodiment of the present invention.

  <First embodiment>

  FIG. 1 is an explanatory diagram of a pipe protector 1 according to a first embodiment of the present invention.

Various pipes are buried underground. Specifically, there are water pipes, gas pipes, sewage pipes, buried pipes for electric wires, buried pipes for various cables, and the like.
These tubes are made of various materials, but are usually made of a material that corrodes a predetermined chemical substance. It is never desirable for any tube to corrode.
Furthermore, in the case of a water pipe or the like, if a chemical substance or the like penetrates into the tap water, there is a possibility that an adverse effect on health may be caused.
To prevent this, made of a material having high-to-Shi resistant to certain chemicals to cover the outside of the tube, or can be used to coat the surface, protective equipment in which sheet into tubular.

However, when laying and embedding the pipe, a tool such as a scoop (shovel) is used. In some cases, heavy equipment may be used.
As described above, when the pipe is buried, there is a possibility that the pipe and the chemical protection sleeve may be damaged by a scoop or the like, or generated soil or crushed stone.
Furthermore, even after the pipe has been buried once, when excavating the pipe, the pipe and chemical protection may be performed using a scoop (if the method of digging is not appropriate, there may be generated soil or crushed stone as well as burial). The sleeve may be damaged.
In addition, when a plurality of pipes are buried, the above-mentioned scoop or the like is similarly used when excavating nearby pipes. This can also damage the tube and the chemical protection sleeve.

Although there are products of other companies for the purpose of preventing damage by a scoop or the like, they are only developed for the purpose of protecting water distribution PE pipes from generated soil or crushed stone. In other words, the protection of the permeation protection sleeve is out of scope, and the product cannot prevent permeation of organic solvents. In addition, since the shape is a character shape and the length is 1 m, it takes time to mount.
Due to these causes, it cannot be said that the product is easy to use, and improvement has been required.

Therefore, it is necessary to provide a pipe protector 1 that can avoid these problems.
In the first embodiment, such a problem is solved by the pipe protector 1 as shown in FIG.
As shown in FIG. 1, a pipe 101 such as a water supply is drawn in so as to cover the pipe 101 from the axial direction of the pipe 101 to cover and protect the pipe.
In FIG. 1, only a part of the tube 101 is covered, but this is a diagram in the middle of being covered, and the entire tube 101 can be protected by moving the tube protector 1 to the left in the drawing.
The pipe 101 may be connected to a joint 102 or another device (for example, an elbow), but the joint 102 and the like can be protected by covering the pipe protector 1.

  The pipe protector 1 has a chemical protection sleeve 11, a physical protection sleeve 21, and a film layer 31.

The chemical protection sleeve 11 has a function of preventing a chemical substance from reaching the pipe 101.
Therefore, the chemical protection sleeve is formed of a material that is not dissolved by the chemical substance. Of course, there is no substance that is resistant to all chemicals, so it is made of nylon, which seems to be more resistant to common substances. However, the present invention is not limited to this. Various materials are conceivable, for example, polypropylene and the like.
The chemical protective sleeve 11 does not necessarily need to be formed of a certain material, but may be made of a substance that is strong against a chemical substance that can be expected to be exposed after the tube 101 is buried.
The chemical protective sleeve 11 has a sheet-like cylindrical shape and may be quite thin. Of course, it goes without saying that there may be some thickness.
This chemical protection sleeve 11 may be transparent. Thereby, when the physical protection sleeve 21 (film) is peeled off, a structure in which the pipe 101 can be directly viewed can be obtained.

A physical protection sleeve 21 is disposed outside the chemical protection sleeve 11 so as to cover the chemical protection sleeve 11.
The chemical protection sleeve 11 has a cylindrical shape of a thick sheet.
This portion is provided to prevent the chemical protection sleeve 11 from being damaged (damaged) by a scoop or the like.
Therefore, the physical protection sleeve 21 needs to be formed with high cut resistance. Also, it is preferable that the shock absorbing property is high.
For this purpose, for example, a structure in which a thread-shaped object (structural material) having high strength is woven is used. There may be a means such as forming with high strength plastic. In order to enhance the shock absorption, a structure of a bubble cushioning material (which is simply called "bubble wrap" of Kawakami Sangyo Co., Ltd.) with a high-strength plastic may be used.
Here, the physical protection sleeve 21 is formed in white. This is to make it possible to see when a later-described film layer 31 is lost.

Alternatively, the physical protection sleeve 21 may be formed from a foam material. In this case, use of a foaming agent material having high cut resistance contributes to higher performance. However, if a certain thickness is made of a foam material, a cut such as a scoop can be prevented even when made of a material having no cut resistance.
In particular, in the case of a foamed material, the foamed material before foaming can be put between the chemical protective sleeve 11 and the film layer 31 and foamed as it is. Therefore, this point is preferable.

A film layer 31 is disposed outside the physical protection sleeve 21 so as to cover the physical protection sleeve 21.
The film layer 31 has a sheet-like cylindrical shape, and may be quite thin. Of course, it goes without saying that there may be some thickness.
On the surface of the film layer 31, a display 32 is printed or the like. This display describes the type (conveyance, display of contents), size (for example, diameter), and the like of the pipe 101 in which the pipe protector 1 is used.
Preferably, the film layer 31 has some cut resistance.
This film layer 31 is formed in blue.
Thus, when the film layer 31 is damaged by a scoop or the like, the color of the underlying physical protection sleeve 21 becomes visible. It should be noted that blue and white are known as two colors having high visibility, and contribute to the discovery of the fact that the operator has been scratched.
The colors of the chemical protection sleeve 11, the physical protection sleeve 21, and the film layer 31 are not intended to be limited to these.

However, the color relationship between the physical protective sleeve 21 and the film layer 31 is preferably higher in visibility such as yellow and black.
Further, the film layer 31 is not essential, and may be only the chemical protection sleeve 11 and the physical protection sleeve 21. In this case, it is preferable that the physical protection sleeve 21 has the display 32.

The chemical protection sleeve 11, the physical protection sleeve 21, and the film layer 31 may be bonded (welded) over the entire surface with, for example, an adhesive.
Adhesion (welding) at a spot instead of the entire surface may be used.
Furthermore, they may simply be in contact with each other without being bonded.

<Configuration and Effect of Embodiment>
The pipe protector 1 of the present embodiment includes a tubular chemical protection sleeve 11 for preventing a chemical substance from reaching the pipe 101 buried underground, and a chemical protection sleeve 11 that covers the outside of the chemical protection sleeve 11. And a physical protection sleeve 21 for preventing physical damage to the device.
With such a configuration, it is possible to prevent the chemical protection sleeve 11 from being destroyed due to a physical attack and not fulfilling the role of chemical protection.

A film layer 31 that covers the outside of the physical protection sleeve 21 and has information about the tube 101 printed thereon.
With such a configuration, the operator can grasp the type of the pipe 101 without opening the pipe protector 1 and checking the inside.

Preferably, the physical protection sleeve 21 is formed by knitting a plurality of thread-like structural materials, or is formed of a foam material.
With such a configuration, the physical protection sleeve 21 can have at least either cut resistance or impact resistance.

The chemical protection sleeve 11 is formed of nylon.
It has such a configuration. And, since nylon generally has resistance to many chemical substances, it is possible to obtain the pipe protector 1 that can cope with many situations without specially custom-made.

The structure, material, connection of each member, chemical substance, and the like of the present invention can be variously changed without changing the gist of the present invention. In particular, the material can be freely selected.
For example, two or more members can be made into one, or conversely, one member can be made up of two or more other members and connected.
Further, the above embodiment is merely one of the best modes at present.
