Description

Manhole with soil-blocker {Manhole with soil-protecter}

The present invention relates to a water supply manhole for inspecting a water supply pipe facility buried in the ground, and more specifically, a double walled tubular manhole body made of a synthetic resin material having a pipe through-hole formed on the lower side of the water supply buried in the ground and the manhole main body. The present invention relates to a manhole provided with a detachable earthen plate on the outside of a pipe through groove formed in the pipe to prevent foreign substances such as soil from entering the pipe through groove.

      In general, the manhole for waterworks is an underground structure installed at regular intervals in order to install a hydrant device for opening, closing, or extinguishing water of a water supply pipe buried underground and a device for maintenance of a water supply facility.

      In addition, the manhole assembly is typically made of a cylindrical body, a floor mounting plate, a pullout and a lid cover, etc. In particular, the cylindrical body serves as a wall to prevent the water supply facilities, etc. located on the inner bottom is buried in the underground soil. On top of that, the tow is usually fixedly integrally coupled.

Figure 1 is an exploded perspective view of an example manhole assembly according to the prior art, a pair of floor mounting plate 12 in the ground to protect a variety of pipes, including a control valve buried to adjust the flow of water in the underground, sewer pipes When the main body 11 of the synthetic resin double-walled pipe supported by) is installed and the iron rod 13 including the manhole cover 14 is coupled to the upper edge of the main body 11, the lower peripheral portion of the iron rod 13 Stepped portion (13a) formed in the wrap around the upper periphery of the main body 11 has a structure that can be combined without a separate fixing means by its own weight. In addition, a lower portion of the main body 11 has a structure in which a pipe through groove 11a having a '∩' shape is formed so that the water supply pipe coupled to the control valve passes.

      However, in the manhole assembly, when the '∩' type pipe through groove is formed wide, the workability is good, but there is a problem in that the soil is easily inserted into the groove to surround the control valve device to corrode the control valve device. In addition, even when the width of the pipe through-hole narrows, a long rectangular groove gap exists and soil is still pushed in, and the construction efficiency is naturally reduced due to the narrow width configuration.

Therefore, the present invention has been made to solve the above problems raised in the conventional manhole assembly, to prevent the intrusion of soil into the manhole body to prevent contamination and corrosion of the control valve device placed therein, and also, the manhole The purpose is to provide a manhole to improve the workability in the installation work.

The above object of the present invention, in the cylindrical manhole body structure formed with a pipe through-hole on the lower side, after the pipe is inserted through the pipe through-hole manhole to prevent soil intrusion into the gap of the pipe through-hole manhole This is achieved by binding to the outer surface of the main body. According to a preferred embodiment of the present invention, the pipe through groove is formed in a '∩' shape for the convenience of construction, the earth plate is made of a pair of left and right structure or a plurality of strip-shaped separation plate, the manhole body It also consists of the upper and lower coupling structure.

      The manhole provided with a retaining plate according to the present invention prevents soil intrusion into the gap of the through-hole of the pipe by inserting a retaining plate on the outside after the pipe is inserted through the pipe through-hole of the manhole body. It is possible to prevent contamination and corrosion of the enclosed control valve device and to form a width of the pipe through grooves in a relaxed manner.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows an exploded perspective view of a manhole structure with a retaining plate according to the present invention.

As shown in FIG. 2, the manhole 100 having the retaining plate according to the present invention includes a manhole body 110 and a retaining plate 120.

The manhole body 110 may also be used as a one-piece cylindrical structure, in order to improve the workability and increase the efficiency of manufacturing in this embodiment uses a double wall tubular upper, lower cylinders (111, 112) structure of high rigid PVC material, the lower cylinder In the lower side of the 112, a '∩' shaped pipe through groove 113 having good workability is formed, and the pipe 114 arranged in a substantially horizontal state passes therethrough, and inside the manhole main body 110, A control valve device (not shown) is installed.

As the first embodiment of the present invention shown in Figure 3, the retaining plate 120 is made of a material such as PP, PE, rubber, the component itself is composed of a pair of left and right structure (120a and 120b), the shape Has a curvature that is appropriately bound to an outer surface of the manhole body 110, and the left and right semicircular pipe passing cutout grooves 121a and 121b which form a hole in the center of the pair of left and right facing surfaces to allow the pipe to pass properly. ) Is formed, respectively, and shows that protrusions 122 are appropriately coupled to the outer circumferential surface of the manhole body 110, that is, the corrugated bone of the double wall pipe, on both inner surfaces of the earthen board 120.

In addition, according to the second embodiment of the present invention, the retaining plate 120 is roughly the manhole body as shown in FIG. 4A in order to preserve the field workability in the upward direction of the retaining plate as in the first embodiment. A band-shaped separation plate 123 having a curvature that is appropriately bound to the outer surface of 110 and forming protrusions 122 that are properly coupled to the corrugated bone of the double wall pipe is coupled to a plurality of inner surfaces at both ends. And, connecting the protrusions 122 formed at both ends is formed in two lines as ribs 124 to guide and fix appropriately in accordance with the shape of the pleats formed on the outer surface of the manhole body 110, ribs 124 or As for the retaining flanges 125a and 125b extending on both sides of the protrusion 122, the radius (curvature) of the flange 125a on one side is larger than the radius of the flange 125b on the other side so that they can overlap each other perpendicularly as possible during assembly. In other words, it is preferable to increase the thickness by the flange thickness. That is, when the center of the protrusion 122 is formed to vary the depth of the flanges on both sides to assemble the plurality of band-shaped separators 123, the band-shaped separator 123 is assembled to prevent the occurrence of gaps. will be. Figure 4b shows that the plurality of strip-shaped separation plate 123 is coupled, as shown in Figure 4b by connecting a couple of strip-shaped separation plate 123 in the field and the pipe of the diameter size of the appropriate pipe in the center portion After cutting for the cutting groove 121 to separate the strip-shaped separating plate 123 one by one to be laminated around the pipe through groove 113.

By the structure as described above, the manhole having a retaining plate according to the present invention is to prevent the soil intrusion into the gap of the through-pipe through the pipe is inserted into the outside after the pipe is inserted through the pipe through the groove of the manhole body. Therefore, it is possible to prevent contamination and corrosion of the control valve device placed inside the manhole body.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only for explaining the invention, and those skilled in the art to which the present invention belongs will various modifications or equivalents from the detailed description of the invention. It will be appreciated that one embodiment is possible. Therefore, the true scope of the present invention should be determined by the technical spirit of the utility model registration claims.
