However, the conventional rainwater mass described above has the following problems.
That is, the overall shape of the rainwater trout (tame trout) made of polypropylene becomes large for manufacturing reasons. As described above, in the case of a large rainwater mass, there is a problem that the rainwater mass itself is large and difficult to handle at the time of construction in a house in a narrow place, and the construction becomes difficult due to the connection with the connected piping.
Moreover, in the rainwater mass made of polyvinyl chloride, the insertion port (receiving port) of the horizontal pulling tube is provided at a position at an angle determined in the circumferential direction.

(First embodiment)
As shown in FIG. 1, the rainwater mass 1 according to the present embodiment is provided in a horizontal pulling pipe 4 that is buried in the ground via a curved pipe portion 23 in a fence 21 of a house (building).
Specifically, as the rainwater drainage of the building of the present embodiment, the rainwater that has flowed to the eaves fence 20 attached to the eaves of the roof is bent with respect to the fence 21 having the drain pipe cover 24 near the ground. It is comprised so that it may flow in through the horizontal draw pipe 4 embed | buried under the ground through 23. The horizontal pipe 4 is connected to the rainwater mass 1 and further drained from the rainwater mass 1 to the sewer pipe (not shown) by the horizontal pipe 4. In addition, the sewage drainage of the drainage facility (for example, the toilet 31) generated indoors is drained from the vertical pipe 25 to the sewage main pipe 30 via a horizontal pulling pipe 26 and a junction not shown.

As shown in FIGS. 2 to 4, the rainwater mass 1 can form an insertion port 13 into which the insertion end 4 a (4 b) for connecting the horizontal pulling pipe 4 shown in FIGS. 5 and 6 is inserted. A mass main body portion 10 having a cylindrical laterally extending outer peripheral wall 10a, and a riser pipe receiving port 11 for connecting a riser pipe 19 extended toward the ground for use in removing mud or the like to the upper end of the mass main body portion 10 And a cylindrical mud reservoir 12 provided at the lower end of the mass body 10.
The rainwater mass 1 of the present embodiment also includes a rainwater infiltration mass in which a plurality of holes are formed in the mud reservoir 12.

  Examples of the material for the rainwater mass 1 include polyvinyl chloride and polypropylene. For example, in terms of cost, polypropylene can be manufactured at low cost. However, as will be described later, the riser pipe 19 cannot be bonded, so that the structure is connected by a joint. On the other hand, polyvinyl chloride is used when the riser 19 can be bonded.

  Here, in the rainwater mass 1 of the present embodiment, the central axes of the mass main body 10, the riser receiving port 11, and the mud reservoir 12 are arranged on a common axis. Hereinafter, this common axis is referred to as the mass axis O, the mud reservoir 12 side of the rainwater mass 1 along the mass axis O direction is referred to as the lower side, and the riser tube receiving port 11 side of the rainwater mass 1 is referred to as the upper side. Further, in a plan view of the rainwater mass 1 viewed from the mass axis O direction, a direction orthogonal to the mass axis O is referred to as a radial direction, and a direction around the mass axis O is referred to as a circumferential direction.

  The mass main body 10 includes continuous portions 10b and 10b that are connected to the riser tube receiving port 11 and the mud reservoir 12 from the laterally extending outer peripheral wall 10a. The laterally extending outer peripheral wall 10a is formed in a cylindrical shape centered on the mass axis O, has an outer diameter of 330 mm or less, and has an outer wall height larger than the diameter of the insertion end 4a (4b) of the laterally extending tube 4. Is set.

  Moreover, the reference line 15 which shows the formation position of the insertion port 13 is displayed on the horizontal insertion outer peripheral wall 10a, as shown in FIG.7 and FIG.8. The first reference line 15A shown in FIG. 7 is displayed from a line extending in the circumferential direction on the outer surface of the laterally extending outer peripheral wall 10a and a plurality of lines extending in the vertical direction (vertical direction) perpendicular to the circumferential direction. . The second reference line 15B shown in FIG. 8 is displayed as a line composed of triple concentric circles every predetermined angle (for example, 45 °) along the circumferential direction.

  The riser tube receiving port 11 has a base end portion 11A connected to the mass main body portion 10 from above and a receiving port main body 11B having a slightly larger diameter than the base end portion 11A. The receiving body 11B is arranged coaxially. The riser pipe 19 is connected to the receiving body 11B by bonding (when the rainwater mass 1 is made of polyvinyl chloride). The riser pipe 19 connected to the rainwater mass 1 has an upper end extending to the ground part, and a protective hat (not shown) is fitted on the upper end part.

  The mud reservoir 12 includes a base end portion 12A connected to the mass main body portion 10 from below, and a mud reservoir main body 12B having a slightly larger diameter than the base end portion 12A. The mud reservoir 12 is formed to have a smaller diameter than the mass body 10, and the outer diameter of the mud reservoir 12 is set to 180 mm or less.

In the rainwater mass 1 configured in this way, as shown in FIG. 5, when the outer diameter of the mass body 10 is 330 mm and the outer diameter of the mud reservoir 12 is 150 mm, the nominal diameter φ100 (outer diameter 114 mm), the insertion angle θ1 between the first horizontal pipes 4A and 4A is 90 °, and the second horizontal pipe 4B having a nominal diameter φ75 (outer diameter 89 mm) is provided between the first horizontal pipes 4A and 4A. Is provided with an insertion angle θ2 of 45 ° with respect to the first horizontal pulling tube 4A. In FIG. 5, symbols C1 and C2 (C) are the central axes of the first horizontal pulling tube 4A, and the angle θ1 between these central axes C1 and C2 is 90 °. Further, in FIG. 5, reference symbol C3 (C) is the central axis of the second horizontal pulling tube 4B, and the angle θ2 with respect to the central axes C1 and C2 of the first horizontal pulling tubes 4A and 4A is 45 °. The insertion end 4a of the first horizontal pulling tube 4A is located at the opening outer peripheral edge of the mud reservoir 12 in a plan view as viewed from above. Further, the insertion end portion 4b of the second horizontal pulling tube 4B is in a position where it comes into contact with the pair of first horizontal pulling tubes 4A, 4A, and the insertion length at this time is secured to 40 mm.
Note that the total length of the rainwater mass 1 is preferably 350 mm or less, and the total length of the mud reservoir 12 is preferably 150 mm or more.

Next, operations of the construction method for connecting the horizontal pipe 4 to the rainwater mass 1 described above, the rainwater mass, and the construction method of the rainwater mass will be described in detail with reference to the drawings.
In the present embodiment, as shown in FIG. 1, when connecting the rainwater mass 1 to the horizontal pulling pipe 4, first, in an arbitrary position of the horizontal pulling outer peripheral wall 10 a of the mass main body 10, FIG. As shown, an insertion hole 13 (see FIGS. 5 and 6) having a predetermined outer diameter is formed by penetrating the laterally extending outer peripheral wall 10a using a drilling jig 5 (opening means). Here, as the drilling jig 5, an electric jig provided with a cutter 52 at the tip of the rotating shaft 51 can be adopted.

  As shown in FIG. 6, the horizontal pulling tube 4 is inserted into the insertion port 13 through the water stop packing 14 to the inside of the mass body 10. Specifically, the water blocking packing 14 is provided between the outer peripheral surface 42 a of the thin end portion 42 of the horizontal pulling tube 4 and the insertion port 13. At this time, the horizontal pulling tube 4 is inserted into the insertion port 13 so that the insertion end 4a (4b) of the horizontal pulling tube 4 is located radially outside the upper end opening edge of the mud reservoir 12 (see FIG. 5). ). The insertion end 4a (4b) of the horizontal pulling tube 4 inserted in this manner can be structured so as not to overlap the opening of the mud reservoir 12 in the mass axis O direction. Thereby, the basket for cleaning the inside of the mud reservoir 12 can be inserted into the mud reservoir 12 without interfering with the horizontal pulling tube 4 into which the basket is inserted.

In the rainwater mass 1 configured as described above, the outer diameter of the mud reservoir 12 is smaller than the outer diameter of the mass main body 10 into which the insertion end 4a of the horizontal pulling tube 4 is inserted, so that the rainwater mass The overall shape of 1 can be reduced. That is, in the rainwater mass 1 of the present embodiment, as shown in FIG. 10A, a space S is formed on the radially outer side of the mud reservoir 12 below the mass body portion 10 in the rainwater mass 1. When the drainage pipe P1 for rainwater and the drainage pipe P2 for sewage generated from the room are arranged in the ground in separate systems in a house or the like, the drainage pipe P2 for sewage may be arranged close to the space S. It becomes possible.
Therefore, the distance L1 between the drainage pipe P1 for rainwater and the drainage pipe P2 for sewage is, for example, the drainage pipe P1 for rainwater in the conventional case using a bucket-shaped slug 1A as shown in FIG. It can be made closer than the distance L2 of the drainage pipe P2 for sewage, and piping can be efficiently installed in a house in a narrow place.

Moreover, in this Embodiment, as shown in FIG. 6, it is predetermined using an opening means (drilling jig 5 shown in FIG. 9) at an arbitrary position on the laterally extending outer peripheral wall 10a of the mass body 10. An insertion port 13 having an outer diameter can be formed, and the horizontal pulling tube 4 can be inserted and connected to the insertion port 13 through the water blocking packing 14 to the inside of the mass main body 10. Thus, the inflow / outflow angle of the horizontal pulling tube 4 can be freely set at the construction site.
Therefore, the inflow / outflow angle of the horizontal pipe 4 can be adjusted or the rainwater can be adjusted like a conventional rainwater mass in which the inlet of the horizontal pipe 4 is provided at a position where the outflow / inflow angle of the horizontal pipe 4 is determined. Problems such as carrying in the wrong shape of the receiving port of the mass can be eliminated, the degree of freedom of piping can be increased, and workability on site can be improved.

When the insertion port 13 having a predetermined outer diameter is formed using an opening means (a punching jig 5 shown in FIG. 9) at an arbitrary position of the laterally extending outer peripheral wall 10a of the mass body portion 10, the laterally extending outer wall 10a is provided with an alignment hole 10g (see FIGS. 12 and 13) corresponding to each hole diameter (for example, 50A, 75A, 100A). The diameter can be formed at a desired position.
Note that, for example, by marking the hole diameter in the alignment hole 10g, it is possible to improve the work efficiency by making it easy to see at a glance which alignment hole 10g is the desired hole diameter.
The alignment holes 10g are preferably formed side by side on the same straight line at the center position of the holes opened by the drilling jig 5, but may be formed by being displaced.

  In addition, in the present embodiment, the horizontal pulling tube 4 is formed so that the outer diameter of the mass body portion 10 is larger than the outer diameter of the mud reservoir portion 12, and is laterally inserted into the outer peripheral portion of the mass body portion 10 to the outer peripheral wall 10a. The insertion length of the insertion end 4a (4b) of the horizontal pulling tube 4 to be inserted can be secured. Therefore, it is possible to reliably perform the connection by inserting the horizontal pulling tube 4, and the insertion end 4a (4b) of the inserted horizontal pulling tube 4 overlaps the opening of the mud reservoir 12 in the mass axis O direction. It becomes possible to make it a structure without. Thereby, the basket for cleaning the inside of the mud reservoir 12 can be inserted into the mud reservoir 12 without interfering with the horizontal pulling tube 4 into which the basket is inserted.

Moreover, in this Embodiment, the member of the small cross section whose outer diameter of the mud reservoir part 12 is 180 mm or less can be comprised, and the rainwater mass 1 can be reduced in size reliably.
Further, since the laterally extending outer peripheral wall 10a is formed in a cylindrical shape and has an outer diameter set to 330 mm or less, for example, a nominal diameter φ100 (outer diameter) that is used as a standard while suppressing the outer diameter of the mass body portion 10 is used. 114 mm) can be inserted into the laterally extending outer peripheral wall 10a.

  Furthermore, in the present embodiment, as shown in FIGS. 7 and 8, the insertion port 13 (see FIG. 7) is formed using a hole opening means at a position aligned with the reference line 15 (15A, 15B) of the laterally extending outer peripheral wall 10a. 5), the positioning work for opening the hole is not necessary, and the insertion port 13 can be formed with high accuracy.

  Thus, in the present embodiment, it is possible to reduce the size, and the outflow / inflow angle of the horizontal pulling tube 4 can be freely set at the construction site, so that the degree of freedom of piping can be increased and The workability in can be improved.

(Second Embodiment)
The rainwater mass 1A of the second embodiment shown in FIGS. 11A and 11B is a base end portion 11A of the riser receiving port 11 in the rainwater mass 1 shown in FIG. 2 according to the first embodiment described above. And the base end portion 12A of the mud reservoir portion 12, and further divided into two parts (upper member 10A, lower member 10B) vertically divided along the mass axis O at the position of the mass main body portion 10. ). That is, the rainwater mass 1A is formed into two members by injection molding and has a structure in which they are joined to each other with an adhesive.
In addition, these two members can also maintain a joint by fitting each member in addition to the adhesive.

  As shown in FIG. 11 (a), the upper member 10A is formed by integrally molding the laterally extending outer peripheral wall 10a of the mass body 10 and the upper connecting portion 10b, and the receiving body 11B of the riser receiving port 11 together. It is a member made. The lower member 10 </ b> B is a member in which the lower continuous portion 10 b of the mass main body 10 and the mud reservoir main body 12 </ b> B of the mud reservoir 12 are integrally injection-molded. In the present embodiment, the connecting portions 10b of the upper member 10A and the lower member 10B form a plane orthogonal to the mass axis O direction, but the continuous portion 10b can also be inclined. By providing an inclination in the continuous portion 10b, mud and water can easily flow into the mud reservoir portion 12.

  The connecting portion 10b of the lower member 10B is formed with a protruding edge portion 10e that extends over the entire circumference of the outer peripheral edge and adheres the lower end portion 10d of the upper member 10A. It arrange | positions in the state which the lower end part 10d of 10 A of upper members fitted to the inner peripheral side of the protruding part 10e, and is adhere | attached with the adhesive agent. A rainwater mass 1A shown in FIG. 11 (b) penetrates a predetermined portion of the laterally extending outer peripheral wall 10a using a drilling jig 5 (see FIG. 9), and an insertion port 13 having a predetermined outer diameter is formed. Is formed.

  The receptacle body 11B extends in a direction intersecting with the continuous portion 10b and is formed with a stopper 10f. Since the stopper 10f is formed, the insertion amount can be controlled when the horizontal pulling tube 4 is inserted so that the insertion end 4a of the horizontal pulling tube 4 does not enter the position of the outer peripheral edge of the mud reservoir 12. it can. Thereby, when the mud collected in the mud reservoir 12 is taken out, a bucket (described later) accommodated in the mud reservoir 12 can be easily taken out.

  In the second embodiment, as described above, the riser receiving port 11 and the mud reservoir 12 omit the base end portions 11A and 12A (see FIG. 2), respectively, so that the overall shape of the rainwater mass 1A is reduced. Can be small. Further, since the upper member 10A and the lower member 10B are manufactured by integrally bonding them, each member can be manufactured not only by injection molding but also using a mold.

(Third embodiment)
As shown in FIGS. 12 to 14, the rainwater mass 1B according to the third embodiment is more specific than the rainwater mass 1A according to the second embodiment described above (see FIGS. 11A and 11B). This is a simple configuration.
The rainwater mass 1B is composed of two members (upper member 6A and lower member 6B) which are divided into upper and lower parts, and can be formed by injection molding or the like. Here, the upper member 6A has a cylindrical laterally extending outer peripheral wall 60 in which an insertion port 60a (see FIG. 13) into which the insertion ends 4a and 4b of the laterally extending tube 4 shown in FIG. 5 are inserted can be formed. It corresponds to the mass body. The upper member 6A has an upper connecting portion 62 connecting a rising pipe receiving port 61 and a laterally extending outer peripheral wall 60 connected to the rising pipe 19 (see FIG. 14) at the upper end, a laterally extending outer peripheral wall 60 and a lower end. And a lower continuous portion 63 for continuously providing the member 6B.

  The rising pipe receiving port 61 is formed of a cylindrical body having a smaller diameter than the laterally extending outer peripheral wall 60. The upper continuous portion 62 is a ring-shaped flange that extends in the circumferential direction by connecting the intermediate portion in the vertical direction of the riser pipe receiving port 61 and the upper end of the laterally extending outer peripheral wall 60. A plurality of reinforcing ribs 64 protruding in the vertical direction are arranged on the upper continuous portion 62 with a gap in the circumferential direction. The upper reinforcing portion 64 </ b> A located on the upper side of the upper continuous portion 62 among the reinforcing ribs 64 is connected to the upper surface 62 a of the upper continuous portion 62 and the outer peripheral surface 61 a of the rising pipe receiving port 61. On the other hand, the lower reinforcing portion 64B located on the lower side of the upper continuous portion 62 includes a lower surface 62b of the upper continuous portion 62, an outer peripheral surface 61a of the riser pipe receiving port 61, and an inner peripheral surface 60c of the laterally extending outer peripheral wall 60. It is connected to the.

When combining the molded upper member 6A and lower member 6B, the rainwater mass 1B is inserted by applying the load from the direction of the axis O of the rainwater mass 1B to the lower member 6B and inserting the upper member 6A. It is formed. At this time, since the reinforcing rib 64 is provided in the upper continuous portion 62, the upper continuous portion 62 is not deformed by applying a load to the laterally extending outer peripheral wall 60 and the upper continuous portion 62 of the upper member 6A. The strength of the rainwater mass 1B can be improved against stress.
Note that the reinforcing ribs 64 need only be formed at locations that do not interfere with the design, and only the upper reinforcing portion 64A is formed at a position outside the rainwater mass 1B as in the third embodiment. The lower reinforcing portion 64B can be formed at a position inside the rainwater mass 1B.

In the upper member 6A, the position of the insertion lower end 61b of the rising pipe 19 in the rising pipe receiving port 61 is positioned below the position of the outer peripheral upper edge 60b of the laterally extending outer peripheral wall 60 of the upper member 6A. Thereby, the riser pipe 19 can be inserted deep inside the rainwater mass 1B, and the rainwater mass 1B can be made compact.
In addition, the position of the insertion lower end 61a into which the rising pipe 19 is inserted is a position below the outer peripheral upper edge portion 60b as described above, and the horizontal pulling pipe inserted into the insertion port 60a of the horizontal pulling outer peripheral wall 60. 4 (see FIG. 5) may be used, and the height can be determined by appropriately adjusting at the time of construction.

  The lower member 6B is detachably connected to the lower continuous portion 63 of the upper member 10A, and corresponds to the above-described cylindrical mud reservoir. The lower member 6B has a smaller diameter than the upper member 6A. The lower member 6B includes a bottomed cylindrical mud reservoir receiving portion 65 and a mounting portion 66 projecting outward from the upper portion of the mud reservoir receiving portion 65 in the radial direction (see FIG. 15). The mounting portion 66 is connected in a state of being fitted to the lower continuous portion 63 of the upper member 6A, and a plurality of reinforcing ribs 67 are provided at intervals in the circumferential direction.

  In this case, as shown in FIG. 16, in the state where the upper member 6A and the lower member 6B are combined, the lower end 67b of the reinforcing rib 67 of the lower member 6B is the upper end of the riser tube receiving port 61 of the upper member 6A. By locking so as to be placed from above with respect to 61c, a plurality of rainwater masses 1B can be stacked and stored so as to overlap in the vertical direction. Here, FIG. 16 shows a state in which a set of rainwater masses 1B are stacked one upon another. With such a configuration, a space for storage can be reduced, and storage efficiency can be improved.

In the modification shown in FIG. 17, a notch 67a is formed on the lower end 67b of the reinforcing rib 67 so that the upper end 61c of the rising pipe receiving port 61 of the upper member 6A is engaged. That is, by engaging the upper end portion 61c of the rising pipe receiving port 61 of the upper member 6A with the notch portion 67a of the lower member 6B, a plurality of rainwater masses 1B are vertically aligned in a state where the upper member 6A and the lower member 6B are combined. Can be stacked and stored in layers.
As another configuration, it is possible to omit the above-described notch 67a by enlarging the hole at the peripheral edge of the lower member 6B. In this case, there is an advantage that a plurality of the holes can be easily stacked.

  Further, in the present embodiment, as shown in FIG. 18, a rainwater mass 1 </ b> B is formed using a mud reservoir bucket 16 provided inside the mass main body 60 so as to be able to be inserted / extracted from the rising pipe receiving port 61 of the upper member 6 </ b> A. It is also possible to accommodate mud that accumulates inside. The bucket 16 has a size that can be accommodated in the mud reservoir receiving portion 65 of the lower member 6B, and is set to a size that does not interfere with the horizontal pulling tube 4 inserted into the upper member 6A when passing through the upper member 6A. . A handle 161 used at the time of taking out is detachably provided on the bucket 16. When the mud accumulated in the bucket 16 is taken out, the mud can be efficiently removed by taking out only the bucket 16 and holding the handle 161. And after removing the mud in the bucket 16, it becomes possible to accommodate the bucket 16 in the mud pool part 12 again.

  For the bucket 16, for example, polyolefin such as polyethylene or polypropylene can be used. In this case, since the hardness is softer than the mud reservoir portion 65 made of vinyl chloride, it is configured with a size that matches the size of the mud reservoir portion 65, so that after the bucket 16 is inserted into the mud reservoir portion 65, It is possible to prevent the bucket 16 from floating due to the buoyancy.

  Further, the bucket 16 may be provided with a receiving portion (not shown) for detachably locking a rod-like member such as a thin tube on the upper surface of the bottom portion. In this case, when removing the bucket 16 from the mud reservoir 65, the bucket 16 can be removed from the rainwater mass 1B by connecting the narrow tube to the receiving port and then pulling up the thin tube. It can be done easily. Note that the length of the narrow tube can be adjusted as appropriate at the time of construction, and the bucket 16 is suppressed by the narrow tube by covering the thin tube, so that the bucket 16 can be prevented from rising due to water.

As mentioned above, although embodiment of the construction method of the rainwater mass and rainwater mass by this invention was described, this invention is not limited to said embodiment, It can change suitably in the range which does not deviate from the meaning. is there.
For example, it is also possible to employ a rainwater infiltration mass as the rainwater mass 1C as in the first modification shown in FIG. This rainwater mass 1C is provided with a large number of small holes 12a, 12a,... On the peripheral surface of the mud reservoir main body 12B on the lower end 1b side of the mud reservoir 12. It becomes possible for mud to flow out into the ground outside the rainwater mass 1C from the numerous small holes 12a together with rainwater. A basket 17 with a handle 18 for avoiding dust is installed in the mud reservoir 12 of the rainwater mass 1C. In the basket 17, a plurality of large holes 17c are formed in the upper portion of the peripheral surface 17a, a plurality of small holes 17d are formed in the lower portion, and a drain hole 17e is formed in the lower end portion. It is possible to prevent clogging of the small holes 12a formed in the lower part of the plate.

  Moreover, in this Embodiment mentioned above, although the mass main-body part 10 is formed in circular shape by planar view seen from upper direction, it is not limited to such a circular cross section. For example, the rainwater mass 1D according to the second modification shown in FIG. 20 may be configured to be formed in a semicircular cross section having a straight portion 10c partially in the mass body portion 10. In this case, since the length dimension of the rainwater mass 1D in the left-right direction in FIG. 20 can be reduced, the space efficiency during installation can be improved. For example, the distance between the rainwater drain pipe and the building can be reduced by arranging the straight portion 10c of the rainwater mass 1D of the second modified example close to the building side, which is efficient in a narrow residential area. The piping can be installed well.

  Further, in the present embodiment, the reference lines 15A and 15B serving as the reference of the position of the insertion port 13 are provided on the laterally extending outer peripheral wall 10a of the mass body portion 10, but the reference lines 15A and 15B are omitted. It is also possible to adopt a reference line with another display.

  The configuration of the shape, size, material, and the like of the mass main body 10 and the mud reservoir 12 of the rainwater mass 1 is not limited to the above-described embodiment, and can be set within an appropriate range. For example, in the present embodiment, the mass main body 10 and the mud reservoir 12 have a cylindrical shape that is circular when viewed from above, but other shapes such as a polygonal shape such as a quadrangle and a hexagon, and an elliptical shape, for example. It does not matter if it is a thing.

  In addition, the constituent elements in the above-described embodiments can be appropriately replaced with known constituent elements without departing from the gist of the present invention.
