Abstract

The present invention relates to a waterproofing device for a connector between a trough and a pipe which connects a connector with a connection pipe in which a branch lead wire is buried between adjacent troughs in which an underground distribution wire is buried so as to conveniently connect the troughs to an underground pipe and fills a filler injection gap formed between the troughs and both ends of the connector by a filler so as to prevent water or foreign materials from invading among the troughs, the connector and the connection pipe, thereby increasing a waterproofing effect.

Description

Waterproof device for connection between trough and piping

The present invention relates to a waterproofing device for connecting a trough and a pipe, and more specifically, it is possible to easily connect a trough in which an underground distribution line is installed and an underground pipe in which a branch lead-in line is installed, and water or foreign substances between the trough and the underground pipe. It relates to a waterproofing device for connecting troughs and pipes that can reliably prevent this intrusion.

In general, a method of protecting the underground distribution line using a trough formed of reinforced concrete is used to install the underground distribution line.

Conventionally, the trough used for laying underground distribution lines consists of a unit trough body formed in a U-shape by reinforced concrete, and a unit trough cover formed in a flat plate shape by reinforced concrete and covered on the upper part of the unit trough body. is composed

In constructing the trap, the unit trap body and unit trap cover of a certain length manufactured in the factory are transported to the construction site, and then a plurality of unit trap bodies are sequentially put into the trench excavated in the ground and connected, and the unit trap is connected. The underground distribution line is inserted into the inside of the main body, and the unit trap cover is covered on the upper part of the unit trap body so that the underground distribution line is protected by the trap.

In addition, the inside of the trap body is composed of a single space or is divided into a plurality of spaces by a plurality of partitions.

On the other hand, in order to supply electricity to a nearby electricity use area through which a trough in which an underground distribution line is installed, an underground distribution line and an electric facility are connected by a branch lead-in line.

Here, electric facilities are provided in places of use such as houses or commercial buildings, and since it is very limited to bury troughs in order to protect branch-in cables at the places of use, underground pipes buried underground are used to protect them.

However, as described above, in order to connect the underground pipe to the trough composed of the trough body formed in the U-shape and the trough cover formed in the flat plate shape, a connection hole must be drilled in the side of the trough body. Therefore, it is virtually impossible to drill a connecting hole.

Therefore, by separating the unit troughs constituting the trough and inserting an underground pipe between them, the branch lead-in cables branched from the underground distribution cables are protected.

However, at the location where the underground piping is connected, there is a gap between the unit trough main body, so water or foreign substances enter the trough and the underground pipe through this gap, and it is impossible to protect the underground distribution line and the branch service line. There is this.

In addition, as prior art, Korean Patent Registration No. 10-1126165 "Construction method of a prefabricated trench-type cable trough built on a railway line" and Korean Patent Registration No. 10-1249300 "cable trough" are disclosed.

However, the prior art also does not solve the problems of the prior art described above because the trough body is composed of reinforced concrete.

In addition, as a prior art, Korean Patent Registration No. 10-2299388 "Leakage prevention connector of underground distribution cable" wraps the top, left and right sides and bottom of a wiring board installed in multiple stages in an underground power outlet and slides along the wiring board, The connector body supporting the first and second distribution cables to be connected, the first and second support walls respectively protruding on both sides of the connector body to prevent the front and rear twisting of the first and second distribution cables; A cover coupled to the upper portion of the second support wall, and a bulging prevention device mounted on the cover to prevent the connection portion from rising due to sagging of the first and second distribution cables by pressing the connection portion of the first and second distribution cables; Disclosed is a technology for preventing water leakage by preventing the connection part of the distribution cable from breaking, including, and providing an induction drain hole for draining water accumulated on the upper surface of the wiring board by forming a space between the connector body and the wiring board.

However, this prior art only prevents the breakage of the connection part of the underground distribution line installed in the trough and protects the underground distribution line from flooding. If it is necessary to do so, a gap is created between the trough and the underground pipe, so it is not possible to prevent the infiltration of water in the trough and the underground pipe, and accordingly, the problem of the prior art that the underground distribution line and the branch-in cable cannot be protected cannot be solved.
