Abstract

(57) [Summary] [Structure] The inner diameter is smaller than the outer diameter of the resin pipe 1 buried in the soil. In addition, it is configured to be divided and connectable in the radial direction. [Effect] The resin pipe is less likely to be damaged, and the protection performance of the resin pipe can be improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective cover for a resin pipe embedded in soil.

[0002]

[Prior Art]

 Conventionally, there is no particular protective cover for the resin pipe, and therefore, the resin pipe is buried in the soil without covering the outer circumference with another object, and the embedded resin pipe is placed at an upper position apart from the buried resin pipe. There was a sign sheet embedded to inform people of their existence.

[0003]

[Problems to be solved by the device]

 However, when the earth and sand around the resin pipe must be dug back by construction equipment, so-called scoops, pickers, etc. was there. However, since there is only earth and sand between the sign sheet and the resin pipe, the excavation working part of the construction machine or the excavator directly and vigorously contacts the outside of the resin pipe, and as a result, There was a problem that the resin pipe was damaged. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a protective cover that can prevent the resin pipe from being easily damaged.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the protective cover of the present invention is characterized in that the inner diameter is formed as a rigid cylindrical body having an inner diameter larger than the outer diameter of the resin tube, and the axial length is greater than that of the resin tube. In addition to being short, it is configured to be divided and connectable in the radial direction.

[0005]

[Action]

 That is, if a cylindrical protective cover is attached to the resin pipe in an externally fitted state, even if another object collides with the resin pipe, the other object first comes into contact with the protective cover, and as a result, The impact force caused by the collision of another object can be received and reduced by the protective cover formed of the hard cylindrical body, so that the resin pipe can be less likely to be damaged. Also, since the length of the protective cover in the axial direction is shorter than that of the resin pipe, the protective cover can be attached to each of the parts of the resin pipe that are subdivided in the axial direction. The protective cover of only a part of the resin pipe can be removed. Further, since the protective cover is configured to be divided and connectable in the radial direction, the protection cover can be attached to and removed from the resin pipe by moving the resin pipe in the radial direction. It is not necessary to remove the protective cover from the resin tube by moving it up to the axis center.

[0006]

[Effect of the device]

 Therefore, even if the excavator accidentally contacts the resin pipe due to civil engineering work, the resin pipe is less likely to be damaged and the protection performance of the resin pipe can be improved. When exposing a part of the resin pipe, such as when attaching a branch pipe to the pipe, it is sufficient to remove only the protective cover at the place where the branch pipe is attached from the resin pipe, and remove all the protective covers in the entire longitudinal direction of the resin pipe. There is no need, and the protective cover can be removed by moving the resin pipe in the radial direction, so the work effort can be reduced.

【Example】

 An embodiment of the protective cover of the present invention will be described below with reference to the drawings. FIG. 1 shows a protective cover 2 attached to a resin pipe 1 buried in the soil.

As shown in FIG. 3, the protective cover 2 is a tubular body, and has an inner diameter larger than the outer diameter of the resin pipe 1. When the protective cover 2 is attached to the resin pipe 1, the protective cover 2 is made of resin. The entire area of the tube 2 in the circumferential direction is covered. Therefore, there is no concern that a part of the resin pipe 1 in the circumferential direction will be exposed. The protective cover 2 is made of steel and has high impact strength.

The length of the protective cover 2 in the axial direction is shorter than that of the resin pipe 1, and only a part of the resin pipe 1 in the axial direction is fitted onto each of the protective covers 2. Therefore, as shown in FIG. 1, in order to directly attach the branch pipe 3 to the outer periphery of the resin pipe, it is sufficient to remove only the protective cover 2 which is arranged at the location where the branch pipe is to be attached.

Further, as shown in FIGS. 2 and 3, the protective cover 2 is formed by a pair of semi-cylindrical members 4. Of the pair of anti-cylindrical members 4, a boss body 6 is integrally connected to the longitudinal center of one side edge of one of the pair of anti-cylindrical members 4, and one side edge of the other side is formed on both ends in the longitudinal direction. The boss bodies 6 are integrally connected, the boss bodies 6 of the one semi-cylindrical member 4 are positioned between the boss bodies 6 of the other semi-cylindrical member 4, and the pins 5 are penetrated through these boss bodies 6. I'm holding it. Therefore, each of the pair of semi-cylindrical members is configured to be rotatable around the pin 5, and the protective cover 2 can be opened and closed in the radial direction.

The protective cover 2 may be made of any material as long as it has the property of being hard. To give a few examples, stainless steel or hard plastic may be used in addition to the steel used in the above-mentioned embodiment.

[Other Embodiment] In addition to the configuration of the above embodiment in which the radial division of the protective cover 2 and the continuous installation are performed by the hinge joint using the boss and the pin, one of a pair of semi-cylindrical members is provided. The structure may be such that one part is provided with a locking part and a locked part that can be locked with the locking part is provided in the other.

The dividing member of the protective cover (corresponding to the pair of semi-cylindrical members in the above embodiment) may be divided into two or more members in the circumferential direction in addition to two or more members.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
