Description

Electrical and telecommunication cables for underground burial of architectural complexes (underground buried architectural complex)

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground conduit for electric and telecommunication cables for underground construction in an architectural complex and, more particularly, to a conduit for underground conduit for electrical and telecommunication cables, Underground installation of a construction complex that can protect the cable inside the underground pipe by preventing the underground pipeline from being damaged by the buckling of the excavator during the repair process, Electric and telecommunication cable underground channel protectors.

Generally, electrical and telecommunication cables embedded in the residential and commercial and industrial parks are installed in underground pipelines for easy installation and protection.

However, these underground pipelines should be repaired after a certain period of time because they are corroded by breakage or penetration water due to self-aging when they are buried for a long time.

In addition to such causes of aging and corrosion, there are cases where maintenance is carried out for reasons such as expansion.

In this way, in order to repair or replace the underground pipeline, a ground embedded with an underground pipeline is excavated to expose the underground line to the outside, and maintenance and replacement work is performed.

Typical excavation work is done quickly and easily using an excavator, which excavates the ground with a bucket installed on the excavator.

Thus, in the course of performing the excavation work, the driver of the excavator can not see the underground railroad buried in the ground, so he can perform the excavation work depending on the operator's skillful sense and operation.

However, when the operator performs the excavation work without knowing the position to the underground line, the bucket of the excavator excessively pressurizes the underground road to destroy the underground roadway. In addition, It is difficult to set an exact excavation position along the underground road, so that there is a problem that the excavation work must be performed while correcting the direction of the excavation at any time.

Conventionally, there is a case where a protection plate is installed on the upper part when the underground pipeline is buried, but such a protection plate is placed on the underground pipeline to prevent direct contact of the bucket with the underground pipeline.

However, such a protection plate has a problem that even if the bucket digs the soil right above the protection plate, it does not know whether or not the protection plate exists, and the bucket breaks the underground line like the protection plate.

If the bucket of the excavator breaks the protection plate, the entire protection plate should be discarded and the other protection plate must be installed after the construction is finished.

In order to solve the above problems, Korean Patent Application No. 10-2008-0007357 (title of invention: underground buried electric wire guard for apartment house) has been introduced.

As shown in FIG. 5, the above-mentioned design is a cylindrical body embedded in the ground and having an underground line disposed therein, with front and rear side bending flanges formed at both ends thereof, and a seat recessed portion formed as a whole around the base of the synthetic resin material A tube;

A rubber tube of a ring type sandwiched between the seat back of the underground pipe and a curved protrusion protruding outwardly in a curved shape is formed on the outer circumference of the tube, Wow;

Wherein a bending flange insertion groove for enclosing and sealing a front side bending flange of another underground tube closely attached to a rear side bending flange of the underground tube is formed at an inner peripheral edge of a ring body made of a rubber material, A connecting rubber ring enclosing and sealing the rubber ring;

And a pair of anchor bolts protruding outward are formed at both ends of the ring body so as to surround the outer surface of the connected rubber ring. The anchor bolts are fastened and fixed by nuts by a fixing plate having an anchor holes into which the respective anchor bolts are respectively inserted, And a left and right fastening rings for preventing the flow of the front and rear bending flanges.

This is because the protection tube is connected to the connection part of the underground pipe and the outer circumference of the underground pipe so that the underground pipe is directly hit and damaged by the bucket of the excavator, thereby protecting the cable inside the underground pipe.

More recently, Korean Patent Application No. 10-2008-0130804 (entitled " underground burial protection line for construction complexes ") has been introduced to solve the above-mentioned problems.

8, a plurality of pile fixing holes and fitting protrusions are formed in the longitudinal direction on both sides of the upper surface of the bottom plate, and the middle portion of both ends in the longitudinal direction of the bottom plate and the fitting protrusions A bottom support plate having a connection seat groove formed therein;

A small electric wire tube having a plurality of small holes at its upper portion formed on the bottom supporting plate and having a large diameter hole and a large diameter hole at the bottom thereof and a fixing member fixed to both sides of the lower surface of the charging pipe in the longitudinal direction, And a plurality of fixing protrusions protruding from both sides of the upper surface of the small conduit;

A protective cover which is seated on the upper surface of the electric wire protecting tube and has a cushioning material of a foamed resin material formed at the center of the bottom surface thereof and is bolted to an upper portion of the electric wire protecting tube;

A connection pipe in which a fixing protrusion portion to be inserted into a connection pipe mounting groove of the bottom support plate is formed on the lower and both sides thereof, a connection pipe through which a large-diameter waterproof pipe of rubber material is inserted, A plurality of small diameter watertight tubes of rubber material;

A plurality of connecting pieces fixed by bolts connecting the wire protecting tube and the connector; And

And a plurality of "C" -shaped fixed piles for fixing the bottom support plate to the ground,

This ensures reliable protection of electric wires buried in the ground for a long time, and prevents breakage of electric wires due to heavy equipment such as an excavator used for maintenance work on lines and sewer pipes.
