Description

Underground protection sheet {PROTECTION SHEET FOR UNDERGROUND PIPE}

The present invention relates to a underground buried protective sheet, more specifically, the strength is good, even if the external force, etc. are not easily damaged, does not corrode well has a semi-permanent life, even if the construction of the bending section, or the construction section is subsided In addition to the role of marking and protection of the buried material, as well as a thin and light weight, easy to load, transport, installation work, and underground storage protection sheet that can reduce the manufacturing cost and installation costs.

In general, various facilities such as water and sewage pipes, gas pipes, and conduits containing transmission and distribution wires are buried in the ground for safety and thermal insulation. These underground facilities require repair and replacement work due to breakage due to self aging and corrosion due to infiltration water after a long time, and work to increase the capacity of each facility. In addition, new work may be undertaken to bury new underground facilities around existing underground facilities.

In order to perform such repairs, replacements, expansions, and new works, the underground facilities are excavated and the underground facilities are exposed to the outside. In the process of carrying out this excavation work, the workers are buried in the ground. Due to the inability to see them, damage and destruction of underground installations occur frequently in the process of operation, and traumatic failures occurring in various construction processes account for about 60% of the total causes of failure of underground distribution cables.

Therefore, when various facilities are buried in the ground, in order to protect these facilities from various hazards, a cover plate or a protective cloth is placed on the upper surface to indicate the location of the installation.

Accordingly, the protective plate of the underground buried facility of general rolled steel material was used, but such a protective plate has a disadvantage in that corrosion occurs when it is buried in the ground for a long time and does not sufficiently serve as a protective plate.

The protective plate is formed of a synthetic resin, for example, polyethylene, but also used, but there is a problem in that the thickness should be increased to increase the strength.

In order to solve this problem, a technique of manufacturing a protective plate using synthetic resin has been disclosed in Korean Patent Registration No. 473128, "Protection Plate for Underground Lines", and Korean Utility Registration No. 153563, "Protection Plate for Underground Works."

However, "protective plate for underground tracks" is produced through injection work, which takes a long time to produce, and is heavy due to a number of recesses, and an isosceles triangle in which protrusions are sharply bent downward at each corner of the plate. There is a risk of safety accidents during transportation because it is formed in the shape of.

In addition, a "protective plate for underground tracks" is formed with a plurality of recesses on the upper surface of the underground tracks by a horizontal convex portion, a vertical convex portion and a border convex portion, and in the case of "protective plate of underground buried" reinforcement protrusions protruding in the longitudinal direction on the surface It is disadvantageous that the mold is expensive to manufacture.

And, "protection plate for underground tracks" and "protection plate of underground buried" both simply listed along the underground facilities of the construction section, as shown in Figure 1 in the case of the bending section (G) of the construction section (1) Since the gap is formed wide between the (10) there was a problem that can not properly perform the role of the protective plate (10).

On the other hand, since the above-described protection plate 10 is not installed in connection with each other, if the area where the underground facility 20 is located in the soft ground, as shown in Figure 2, each of the protection plate 10 when the ground subsides due to heavy rain, etc. Since they are buried in different positions there was a problem that can not perform the role of the protective plate (10).
