Abstract

PURPOSE:To provide a public catch basin having a function of absorbing a distance of the burying depth between a public catch basin belonging to public sewerage installation and the terminal end of a drain pipe belonging to an indoor drain installation. CONSTITUTION:A pipe member 30 is erected after being connected to the sewage inlet part 21 of a catch basin body 20 having a sewage outflow port part 22 and a joint member 40 having a lateral sewage inlet part 42 is connected to the pipe member 30. The pipe member 30 is cut off to adjust the length L1 thereof so that the position of the sewage inlet part 42 can be connected to conform to the terminal position of a drain pipe 1. Thus, a distance H between the burying depth of the position of the public catch basin A and that of the terminal end position of the drain pipe 1 is absorbed.

When constructing such a sewerage facility in a land, etc., the procedure is to construct the main sewage system under the public road, the public basin and the mounting pipe first, and the domestic drainage facility after the construction of the house. Therefore, it takes a considerably long time from the completion of construction of the main sewer system, public basin, and installation pipe as public sewer facilities to the construction of the domestic drainage system. For this reason, for public basins, the sewage inflow side is closed with a cap until the house drainage system is constructed, and only the sewage outflow side is connected to the sewage main line with a joint or mounting pipe, After construction, the cap on the sewage inflow side is removed and connected to the in-house water distribution facility. Also, while the public basin is buried deep enough based on the burial depth of the sewage main, construction of the in-house drainage facility is carried out from the farthest place (starting point) from the public basin of the house. The burial depth is 20c at the starting point
In-house drainage pipes and in-house pits will be installed at a shallow depth of about m. The flow gradient of the sewage set in the drainage channel in the residential area by the construction is about several percent. For this reason, there is often a large gap between the burial depth of the domestic drainage pipes and basins installed at the final point in the residential land and the burial depth of the public basin. The gravel will be buried in a place much shallower than the public gravel.

Therefore, conventionally, as shown in FIG. 3, an indoor basin which is commonly referred to as a drop basin as a final premises in the domestic drainage pipe 1 (hereinafter referred to as an indoor basin to distinguish it from other premises) 2 The drop drop 2 in the house absorbs a large gap H between the burial depth of the domestic drainage pipe 1 and the burial depth of the public basin 3. In addition, 4 is an inspection tube which is raised from the drop box 2 in the house, 5 is a short pipe which is lowered from the drop box 2 in the house, 6 is an elbow-shaped bent pipe, and 7 is the bent pipe 6 and the public rod 3 are connected.

However, when the in-house drainage facility is constructed, as described with reference to FIG. 3, the in-home drop basin 2 causes the depth of the premises drainage pipe 1 and the burial depth of the public basin 3 to be different from each other. When the construction method of absorbing the gap H is performed, in order to connect the sewage inflow side of the existing public basin 3 and the connecting pipe 7, a wide range from the in-home drop basin 2 to the public basin 3 to the bottom of the public basin 3 It is necessary to dig deep, and the area to be dug at that time is considerably wide and the depth is considerably deep. For this reason, the conventional construction method using the in-home drop basin 2 is the in-home drop basin 2 and the connecting pipe 7.
It is inevitable to carry out large-scale excavation work in a wide range to install necessary materials such as. Moreover, it is difficult to dig up a large area in a small residential area where the installation space for in-house drainage facilities must be small, so a small-diameter drainage basin that has recently been especially prized in a small residential area ( There is a problem that it is difficult to apply the above construction method to a domestic drainage facility using a drainage basin having a diameter of 200 mm or less. In addition, conventionally, regardless of whether it is a domestic drainage facility using a small-diameter drainage basin, an indoor drop basin 2
There was also a problem that the construction cost was increased due to the extra requirement.

Further, although the joint member 40 of the embodiment is a so-called T-shaped joint member having one connection port portion 43, it is possible to provide a plurality of side wall sewage inlet portions at a plurality of positions on the peripheral wall 41. It is also possible to connect the end of the in-house drainage pipe. Further, the main body 20
Connection portion between the connection opening portion 25 and the lower end portion 32 of the pipe member 30, a connection portion between the upper end portion 31 of the pipe material 30 and the first connection opening portion 45 of the joint member 40, and a second connection opening portion of the joint member 40. The inner space of the drainage basin A is formed by joining the connection point between the drainage pipe 46 and the lower end portion 51 of the tubular body 50 and the connection point between the connection port portion 43 of the joint member 40 and the end of the domestic drainage pipe 1 with an adhesive. However, the water-tightness is surely blocked from the outside, and the intrusion and leakage of unknown water are surely prevented, and at the same time, the frost heave phenomenon in the cold region is also surely prevented. As described above, it is possible to maintain the reliable watertightness and prevent the frost heave phenomenon by joining the connection points by using the adhesive.
This is because the pipe material 30, the joint member 40, and the tubular body 50 are made of vinyl chloride resin.

The drainage basin as a public basin according to the invention of claim 1 has a function of itself capable of directly connecting the premises drainage facility by absorbing the gap in the burying depth from the home drainage facility. Since it has such a space, it is possible to connect to the in-house drainage facility without using the in-home drop box, and as a result, the in-home drop box becomes unnecessary. In addition, by eliminating the need for an in-house drop basin, the area for excavating the land is small and the depth can be shallow when connecting to the in-house drainage facility, which not only reduces the construction cost but is also suitable for a small residential area. It can be used very advantageously as a small-diameter drainage tub that has recently been especially prized as a domestic drainage facility. The same action is achieved by the invention of claim 2.

Further, the drainage basin as a public basin according to the present invention has the directional flexibility that the direction of the sewage inlet of the joint member can be changed steplessly within the range of 360 degrees around the joint. In addition to the advantage that the sewage inlet part can be connected to the end of the domestic drainage pipe guided from the direction, the sill body, pipe material and joint member are made of vinyl chloride resin Can be joined with an adhesive, and by doing so, it is possible to reliably prevent intrusion of unknown water and water leakage.
