Problems solved by technology

[0006] As mentioned above, when installing the drainage manhole, if the front and rear drainage pipes are round pipes of different types and different diameters, it is necessary to prepare several different types of pipe connection joints in advance or special parts such as different-diameter pipe connection joints, and it takes time to install these parts on the round pipe and adjust the type and diameter of the pipe
In addition, there is a problem that the special discharge volume for connecting unstandardized piping such as ribbed pipes is expensive

Embodiment 1

[0120] The drainage manhole 1 of the present invention is composed of a drainage manhole main body 2 provided with casing sockets 21a, 21b, and upstream side and downstream side casings fitted with the casing sockets. The maximum nominal diameter of the various round pipes is determined, and the upstream side casing and the downstream side casing are determined by the combination of the type and nominal diameter of the drainage manhole main body 2 and the cylinder. The casing sockets 21a, 21b have Figure 5 Shape dimensions shown.

[0121] According to Table 1, the number of each round pipe in the range of nominal diameter: DN110 to 500 is all 20 types. As a result, it can be understood that at least 20 types of drainage manholes must be prepared as the corresponding drainage manholes.

[0122] However, according to the present invention, as shown in Table 5, the drainage manhole 1 including the drainage manhole main body 2 and the sleeve sockets 21a, 21b provided on the main...

Embodiment 2

[0130] The drainage manhole 1 of the present invention is composed of a drainage manhole main body 2 provided with sleeve sockets 21a, 21b, and upstream side and downstream side sleeves fitted with the sleeve sockets. The drainage manhole main body 2 is composed of The maximum nominal diameter of the various round pipes is determined, and the upstream side casing and the downstream side casing are determined by the combination of the type and nominal diameter of the drainage manhole main body 2 and the cylinder. The casing sockets 21a, 21b have Figure 5 Shape dimensions shown.

[0131] Figure 6 as well as Figure 7 Example 2 shown in is the case where the nominal diameter of the corrugated pipe 3' connected to the upstream side is DN200 (the actual outer diameter is 183 mm), and the corresponding nominal diameter of the ribbed pipe 4' connected to the downstream side is It is DN225 (the actual outer diameter is 225mm). Thereby, with respect to the drainage manhole 1 prep...

Embodiment 3

[0138] Figure 8 Represent the plan view of embodiment 3, Figure 9 Indicates that the A-A section is cut Figure 8 The drainage manhole 1' of the present invention shown in.

[0139]The drainage manhole 1' of the present invention is generally made of resin such as vinyl chloride or polypropylene, and consists of a main body 200 and a sleeve. In addition, as shown in Embodiments 1 and 2 above, the shapes of the casing sockets 210a to 214a provided on the upstream side and the casing sockets 210b provided on the downstream side are combined based on the nominal diameter of the ribbed pipe. It has substantially the same shape as the bushing sockets 21a and 21b (see Tables 1 and 5).

[0140] Therefore, the structure of the main body 200 is similar to that of the usual four confluence type drains, except that the sleeve sockets 210a to 214a, 210b have a given shape in which the length in the axial direction is shorter than that of the usual circular pipe sockets and spigots. ...

Abstract

Provided is a different type, different diameter connection drainage manhole comprising a drainage manhole body provided with an upward inspection cylinder connecting part and a socket receiving port for connecting a socket to the upstream side and the downstream side; an upstream side socket having a drainage manhole body spigot fitted to the socket receiving port and connected to the drainage manhole body on one end and a circular pipe receiving port to be joined by a rubber ring to the circular pipe on the other end; an upstream side socket having a drainage manhole body spigot fitted to the socket receiving port and connected to the drainage manhole body on one end and a circular pipe socket to be joined by a rubber ring to the circular pipe on the other end; wherein the drainage manhole body is determined by a maximum nominal diameter in the various circular pipes to be connected, and the upstream side socket and the downstream side socket are determined by a combination of the drainage manhole body and a kind and a nominal diameter of circular pipe. So that different type, different diameter circular pipes can be connected by one drainage manhole.

Description

technical field [0001] The present invention relates to a drainage manhole for connecting round pipes of different types and different diameters, and particularly relates to the case where the types and / or calibers of the round pipes connected to the upstream side of the drainage manhole and the round pipes connected to the downstream side are different, There is no need for special pipe joints, and a drainage manhole determined by the maximum nominal diameter of the above-mentioned connected various round pipes can be used to connect different kinds of pipes with different diameters. Background technique [0002] When constructing drainage piping, drainage manholes are often provided in the middle of the route for inspection of the buried piping or for merging other drainage piping. At this time, most of the drainage manholes under construction are often used to connect new pipes to existing pipes, etc. If the buried pipes are not excavated for inspection, it may not be pos...
