It is necessary to perform on-site construction in accordance with changes in the length, angle, direction, etc. of the buried pipe. According to the conventional buried pipe protection cover described above, since it is made of a hard metal plate, it is easy to take time for processing and construction, and the workability at the site is deteriorated,
During storage, there is a problem that it is bulky because it is stacked and stored, it is heavy during transportation, and it is necessary to prepare various shapes that match the pipe diameter. An object of the present invention is to provide a buried pipe protection cover which has good workability, is hard to be bulky, is lightweight, and can protect a single kind of buried pipe of various pipe diameters in view of the above drawbacks.

ら、外力による埋設管の破損を防止することができる。According to the feature of the first aspect of the present invention, the sheet is made of a high-strength fiber layer and a flexible elastic body at a position above the buried pipe at a distance. Since the cover is formed, even if another object tries to collide with the buried pipe, the other object first comes into contact with the protective cover, and as a result, the impact force accompanying the collision of the other object is reduced with high strength. In addition, since the protective cover having high elasticity can receive and absorb and absorb the impact, the buried pipe can be hardly damaged. Further, since it is formed in a flexible sheet shape, it can be stored in a state of being wound in the longitudinal direction, and can be easily processed and constructed into a shape corresponding to various pipe diameters. Therefore, the buried pipe can be prevented from being damaged by an external force, while being lighter and less bulky than a metal-made material and improving workability at the site.

Since the fiber layer is formed, the reinforcing layer has a reinforcing effect and can prevent the buried pipe from being damaged by an extreme impact force. Further, among the high-strength fibers, Kepler fiber is strong against heat, so that it is possible to protect a buried pipe made of polyethylene pipe which is weak against heat from heat. Therefore, it is possible to protect the buried pipe from heat and prevent damage due to external force.

And the impact can be relaxed and absorbed, so that the buried pipe can be hardly damaged. Therefore, it is possible to prevent the buried pipe from being damaged by external force while improving the workability at the site.
