Description

Water pipe for manhole {Waterproof pipe for manhole}

The present invention relates to a waterproof pipe body installed in the duct of the electrical and communication manhole, more specifically, the waterproof pipe body embedded in the concrete manhole using formwork is formed in a mutually divided and assembled form, between the divided waterproof pipe body By inserting the exponential packing, the split waterproof tube adopts mutually pressurized fastening structure, so that the manhole which can quickly and effectively assemble the inherent waterproof tube with exponential packing and efficiently apply the excellent exponential waterproof tube to the manhole's pipeline It relates to a pipeline for waterproof pipe.

In general, in the case of electric or telecommunication manhole made by concrete mortar, the concrete is placed in the form and inserted into various forms of waterproof pipes in the formwork of concrete. The pipeline is formed by the waterproof tube penetrating the outside.

At this time, the waterproof pipe body forming the pipe hole basically serves as a connection path between the manholes for various cables, but blocks rainwater, groundwater or peripheral leachate that is to be introduced into the manhole through the pipe hole from the outside of the manhole. To serve as a waterproof means to do, it is common that the water or waterproof means of various forms and structures are applied.

Such a water pipe for the pipeline has a length corresponding to the thickness of the wall of the manhole may be formed in one or a plurality of the manhole on one side or both walls, the above water-proof tube is the waterproof when the cable is installed between the manhole The plug is connected to the cable by removing the plug at the same time as the cable is inserted into the waterproof pipe in a state in which the plug is temporarily blocked by the pipe.

In the prior art of the manhole duct waterproof device or waterproof tube, the manhole is installed for connection and branching when installing electric wires and communication lines in the ground, as in Korean Utility Model No. 20-1999-0035265. The coupling structure of the waterproofing device for the pipeline to prevent water from flowing into the manhole while guiding the inside of the manhole. It simplifies the installation and manufacturing process and increases the reliability of the facility to protect the wire by preventing leakage during installation. By simplifying the manufacturing process, the coupling structure of the waterproofing device for the pipeline has been devised to reduce the manufacturing cost and facilitate the work during installation and shorten the installation time to increase the work efficiency.

In addition, as in the Utility Model Registration No. 20-0176389, when forming electrical and communication manholes, it relates to a waterproof pipe which is formed in the mold with the same length as the thickness of the concrete wall and integrally formed with the wall of the structure. If it is not used through a stopper that is easily opened and closed, the waterproofing is made by blocking and when used, the waterproofing tube opening and closing stopper that can be easily removed by rotating it has been conceived and registered.

Subsequently, as in the Utility Model Registration No. 20-0372423, the pipe groove waterproofing pipe which cuts the cutting groove of the screw body installed inside the waterproof pipe by a certain length unit and connects it continuously to the desired length according to the wall thickness of the structure. The regulating device has been devised and registered.

In addition, as shown in Korean Patent Publication No. 10-2012-0102946, the body is hollow and penetrates from one end to the other end of the body, and the one end has a predetermined gap spaced in a spiral direction in the direction of the center of the body on the inner side. And a first coupling groove formed as much as the first coupling groove, and the other end is rotatably coupled to the first coupling groove and the connecting means including a second coupling groove formed at a predetermined interval in a direction toward the center of the body in a spiral uneven portion on an inner side thereof. In addition, a pipe line waterproofing device including a straight pipe coupled to the second coupling groove by rotatable and a pipe line waterproof straight pipe connected through the connecting means has been conceived.

However, the existing manhole waterproofing device for the manhole is assembled after the concrete is laid and cured in the manhole, or is made of a buried integrated structure, which does not perform an effective exponential action, and because the waterproof structure for the inside of the pipeline is not applied. After the connection work of the high cost waterproof or water-proof work to be performed additionally.

In other words, in the case of assembling the waterproof pipe or waterproofing device in the manhole made of concrete, the exponential action is inevitably reduced due to assembly error or gap in the assembly part. As leachate from farms and farms flows in, safety accidents occur due to short circuits or short circuits in the manholes.

In addition, the waterproof pipe or waterproof device made of an integral structure will exhibit a relatively good exponential action, but rainwater or groundwater is flowing into the manhole through the gap between the concrete and the waterproof pipe, and the waterproof pipe or the waterproof device itself Since the water structure is not applied to the interior, rainwater or groundwater flows into the manhole between the waterproof pipe or the waterproof device and the cable.

In particular, in the case of a waterproof unit having a unitary structure, it does not correspond to the thickness of the wall of the manhole that can be constructed with various wall thicknesses, so it is inevitable to separately manufacture a waterproof unit having various lengths, and the length of the screw assembly length is extended. In the case of the waterproof device having a structure, the rainwater or groundwater flows into the manhole from the outside of the manhole through the screw assembly due to the fragile structure in the screw assembly.
