Description

Ground protection plate {Safety protection plate for underground cable}

The present invention relates to an underground buried safety protection plate installed above the buried pipe so that underground buried buried in the ground can be safely protected during the excavation work, even if the underground buried works such as communication and electrical cables or gas pipes inadvertently As the protection plate above the buried pipe is broken, the worker can visually and surely transmit a caution signal to the underground buried material safety protection plate that can structurally prevent the accident of the buried underground pipe.

In general, as the industrialization and informatization are accelerated, the power consumption and information communication volume are rapidly increasing, and their supply is supplied from the production site to the consumer via cable.

These cables are usually laid in the ground in consideration of the urban aesthetics and movement obstacles of people or vehicles.In general, these cables are often laid in the ground spaced from a sidewalk or the ground. When excavation work such as repair of roads, repair of cables, and additional installations are normally under the condition that the cable protected by buried pipe is buried underground, it is inevitable to use the excavator to excavate the ground.

However, in the process of the excavation work, the worker (excavator driver) does not see the buried pipe buried in the ground (soil), so the excavation work is carried out with the operator's sense. When the sensor detects the excavation work, the bucket is moved so that the bucket does not touch the underground line.

However, there is a frequent occurrence that the cable inside the buried pipe buried in the middle of the work is frequently damaged while the worker's carelessness and the cable laying condition are not fully understood. In addition, since the worker does not know the buried position of the buried pipe, it is difficult to set the exact excavation position along the buried pipe, and there is a inconvenience in that the digging work should be performed while modifying the excavation progress direction from time to time.

On the other hand, to improve the problem that the bucket bucket of the excavator accidentally breaks the buried pipe during the excavation work, as shown in Figures 1 and 2, a separate protective plate 80 on the buried pipe 60 together underground (70 ), The buried bucket of the excavator is prevented from being damaged by the bucket of the excavator during the excavation work.

By the way, most of the buried pipe protection plate 80 is formed so as to protrude into a plurality of reinforcing protrusions 82 of the upper side of the main body in the form of a lattice, and a support projection 84 in the form of a triangular pyramid protrudes on the opposite lower edge. This prevents the bucket from directly touching and burying the buried pipe 60 by making it possible to feel the bucket of the excavator touching the protective plate 80 above the buried pipe 60 before the bucket of the excavator touches the buried pipe 60 during the excavation work. It is doing so.

However, in reality, when the excavation work is noisy in the working environment due to the noise of the worker does not sense the bucket touches the shield 60, but the buried pipe (60) by touching the buried pipe (60) below the shield 60 It is difficult to reliably prevent the cable from causing serious damage and destruction.

Therefore, in the present invention, when the worker accidentally touches the protective plate with the bucket of the excavator due to the poor working environment during the excavation with a loud noise, the protective plate is naturally damaged and the contents of the fluid or powder filled in the protective plate are scattered momentarily. A warning signal can be visually transmitted to the operator, resulting in the operator providing a safer and safer underground cover that not only makes the excavation work more comfortable and safer, but also structurally reduces safety accidents. There is a purpose.

The underground buried material safety protection plate of the present invention for achieving the above object, the upper plate through which the fastening bolt is fastened to the space of the space projection and the upper side wall while the space projection protrudes into the upper side wall of the outer side, and the outside A lower plate protruding into the lower side wall of the lower plate which protrudes a bolt body in which a fixing bolt is coupled to the space protrusion and the lower side wall space while a receiving chamber is formed in which the contents are filled in the inner space together with the space protrusion of the upper plate; The product is configured to include a closure plug penetrating one side of the lower side wall of the lower plate and extending into the accommodation chamber to open and close the injection port, which is the injection passage of the contents.

In addition, above the space projection of the lower plate, a relatively soft packing of PVC is installed so that the space protrusion of the upper plate and the airtightness are maintained. In particular, the contents filled in the storage chamber between the lower plate and the upper plate are colored liquid or powder. Any one of the flours may optionally be applied.

According to the underground protection safety plate of the present invention, even if inadvertent excavation work occurs in underground works such as communication and electrical cables or gas pipes, the protective plate above the buried pipe is damaged and the liquid or powder having the color filled in the receiving chamber of the protection plate. It is expected to be able to deliver a clear visual attention signal to the worker as it is scattered momentarily, so that the worker can work on the excavation work with a relatively comfortable mind, and also dramatically reduce the accidental safety accidents due to structural errors. .

Hereinafter, with reference to the accompanying drawings of the preferred embodiment of the concrete configuration and operation of the buried safety protection plate of the present invention will be described in detail.

3 and 4 and 5 is a cross-sectional structure of the external structure and the coupled state of the bonded state and the separated state of the underground buried pipe safety protection plate according to the present invention, respectively, Figure 6a and 6b is the underground laying of the present invention The protective plate 10, which is a safety protective plate for the construction, is placed on the buried material 60 of the underground 70, and the upper plate 20 of the protective plate 10 is damaged by the bucket of the excavator during the installation state and the excavation work. It shows the operating state in which the contents 50 of 40) are instantaneously scattered. In general, the buried pipe 70 is accommodated in communication and electrical cables, and the like, the buried pipe itself can be installed by applying a gas pipe and various other pipes, of course.

As shown in the figure, the protective plate 10 is a buried safety protection plate 10 of the present invention, each of the space projections 22 of a predetermined height so that the storage chamber 40 is filled with the contents 50 are basically formed therein. ) 32 is formed by the combination of the upper plate 20 and the lower plate 30 protruding.

First, the upper plate 20 has a space protrusion 22 protruding into the outer side wall 26 of the outer side wall, and a fixing bolt 12 is formed in the space between the space protrusion 22 and the upper side wall 26. The bolt fastening hole 24 which can be fastened is penetrated, and the bolt fastening hole 24 is a space between the space protrusion 22 and the upper side wall 26 as well as a space inside the upper side wall 26 ( It is also preferred to be formed on the 40) side so that a more solid bolt coupling can be made.

The lower plate 30 has a space protrusion 32 protruding into the lower side wall 36 of the outer side wall, which is also an outer side wall, and the contents 50 in the inner space together with the space protrusion 22 of the upper plate 20. ) Is filled with the receiving chamber 40 is formed, and the fixing bolt 12 is also in the space of the space protrusion 32 and the lower side wall 36 and the receiving chamber 40 which is the space inside the space protrusion 32. The bolt fastening end 34 to be protruded. Of course, the bolt fastening end 34 is formed at the same position as the bolt fastening hole 24 of the upper plate 20, and in some cases, the bolt fastening hole 24 and the lower plate 30 of the upper plate 20. The bolt fastening end 34 may be formed to be interchanged with each other.

In addition, the protection plate 10 has an injection hole 42, which is an injection passage of the contents 50, is formed on one side of the lower side wall 36 of the lower plate 30, and the injection hole 42 extends to the accommodation chamber 40 to the outside. In the contents 50 can be injected into the storage chamber 40 simply and conveniently. Of course, the injection hole 42 is coupled to the closure plug 44 which is an opening and closing means.

In addition, the space projections 32 of the lower plate are relatively soft, unlike those of the space projections 22 and 32, which are made of hard PVC, so that the airtightness with the space protrusions 22 of the upper plate can be structurally improved. It is preferable that the airtight packing 14 made of a material is applied, and furthermore, the space protrusion 22 of the upper plate is applied in the form of a recess unlike the space protrusion 32 of the lower plate which is a protrusion so that the airtight packing 14 is tightly inserted. To be kept confidential.

In addition, the lower plate and the upper plate is accommodated so that the scattering effect of the contents 50 filled in the accommodating chamber 40, which is a characteristic function of the present invention, can be more reliably provided when a safety accident occurs due to an operator's mistake during the excavation work. The content 50 filled in the seal 40 may be a variety of liquid or powdered powder having a color. Of course, the storage chamber 40 of the protective plate 10 is in a vacuum state so that the scattering effect of the contents can be made structurally surely, the appropriate pressure is more reliably generated in a state in which a liquid such as water as well as powders of various colors are filled. The scattering effect of the contents can be maximized.

In addition, the upper surface of the upper plate 20 to which the bucket bucket of the excavator first of the protective plate 10 constituting the present invention protrudes a friction protrusion 28 of a certain height, and the worker hears when a light contact is not a strong contact In general, it is desirable to allow the excavator to more easily recognize scratching the protective plate 10.
