Description

  The present invention relates to a diverter for draining inflow rainwater to a plurality of drainage destinations and a diversion system using the diverter.

  Conventionally, various structures and treatment methods for treating rainwater have been proposed (see, for example, Patent Documents 1 to 3). In fact, a water distribution system 100 as shown in FIGS. 5a and 5b has already been provided. In the water diversion system 100, a water diverter 101 is embedded in the vicinity of a side groove 111 (or a rainwater main), and the diverter distiller 101 has a main body 102 made of concrete. Then, on the side wall of the diverter main body 102, an inlet 103 for connecting the inflow drain pipe 110, a first outlet 104 for connecting the drain pipe communicating with the side groove 111, a tank, etc. And a second outlet 105 for connecting a drain pipe communicating with the permeation facility 112. The first outlet 104 is provided at a position lower than the inlet 103, and the second outlet 105 is provided at a height position between the inlet 103 and the first outlet 104. It has been. As a result, the rainwater that has flowed into the diversion vessel 101 through the inflow drainage pipe 110 is first drained into the gutter 111, and the amount of water increases due to guerrilla heavy rain and the like. When the amount of rainwater flowing into the diverted water mass 101 from the inlet 103 becomes larger than the amount of rainwater flowing into the water 111, the water is appropriately and smoothly drained into the infiltration facility 112.

  However, in the above-mentioned concrete water diverter, each opening is arranged at a different height, and it is determined in advance whether the drain pipe connected to each opening is for inflow or for outflow. For this reason, the arrangement of the inflow drain pipe or the outflow drain pipe is limited around the diverter, and the diverter of the conventional configuration has a problem that the degree of freedom in piping design is extremely low. . On the other hand, in order to solve such a problem, if an attempt is made to prepare a wide variety of concrete diverters in advance, waste is likely to occur, resulting in a problem that the product cost increases as a whole.

  Therefore, an object of the present invention is to provide a water distribution system having a high degree of freedom in piping design and a water distribution system using the same.

The present invention includes a bottomed cylindrical main body, and rainwater flowing into the main body through at least one inflow drain pipe connected to the main body is supplied with a plurality of rainwaters connected to the main body. This is a divide that drains out of the main body through the drainage drain pipe, and the side wall of the main body is connected to a drainage destination excluding a tank having a permeation function. Multiple outlets that can be connected to a reference outlet to which a drainage drain main pipe to be drained preferentially is connected, an outlet drainage sub-pipe different from the drainage drain main pipe, and an inflow drain pipe And the lower ends of the plurality of inlet / outlet ports are set higher than the lower end of the reference outlet in the main body and set to the same height as each other. At the position connected to the inflow / outlet port. The bottoms of the outflow drainage sub-pipe and the inflow drainage pipe are arranged at a position higher than the bottom of the outflow drainage main pipe at the position connected to the reference outlet, and are arranged at the same height. Further, there are two or more inflow / outlet ports other than the inflow / outlet port to which one inflow drainage pipe is connected at a plurality of outflow / inlet ports, and at least the outflow drainage sub-tube is connected to the outflow / inlet port. In the main body, the divide is characterized in that no connecting pipe is connected between the inflow drain pipe and the outflow drain sub pipe. In addition, a cap that closes the opening of the inflow / outflow port may be attached to the outflow / inflow port that is connected to the outflow / inflow port, and neither the outflow drainage sub-pipe nor the inflow drainage tube is connected to. Good.

  In such a configuration, an outflow drainage main pipe connected to a drainage destination to be drained with the highest priority among the outflow drainage pipes connected to the water diverter is connected to the reference outlet. In addition, as the inflow drainage pipe connected to the diverter, an outflow / inlet port at a position most convenient for piping is selected and connected to the outflow / inlet port. Further, the outflow drain sub-pipe different from the outflow drain main pipe is appropriately selected as an outflow / inlet port at a suitable position and connected to the outflow / inlet port. Here, since the plurality of inlet / outlet ports are arranged higher than the reference outlet, the rainwater guided into the water diverter by the inflow drain pipe is first discharged from the reference outlet to the outside. It will be drained. In addition, the inflow / outlet ports are aligned at the same height, and drainage pipes can be connected regardless of whether they are for inflow or outflow. And connected to the basin. As described above, the water diverter of the present invention increases the degree of freedom in piping design for the drainage drainage sub-pipe and the drainage drainage pipe while securing the drainage route to the drainage drainage main pipe that should be given the highest priority. it can. In the present invention, the outflow drain main pipe and the outflow drain sub pipe are included in the outflow drain pipe, and when explaining the outflow drain main pipe and / or the outflow drain sub pipe Is sometimes referred to as an outflow drain or drain.

  In addition, the inflow / outlet port to which the inflow drainage pipe is connected and the outflow / inflow port to which the outflow drainage sub pipe is connected are opposed to each other, and the inflow / outflow port to which the inflow drainage pipe is connected The distance D between the outlet and the inflow / outlet port to which the outflow drainage pipe is connected is such that D ≧ 3d with respect to the diameter d of the outflow / inlet port to which the inflow drainage pipe is connected. preferable.

  Here, when the inflow / outlet port to which the inflow drainage pipe is connected and the outflow / inflow port to which the outflow drainage sub pipe is connected are opposed to each other, the outflow to which the inflow drainage pipe is connected There is a risk that rainwater that has flowed into the diversion chamber from the inlet / outlet directly flows into the outlet / outlet port connected to the outlet drainage sub-tube instead of the reference outlet. Therefore, the distance D and the diameter d are set as described above, and the distance between the inflow / outlet port connected to the inflow drainage pipe and the outflow / inflow port connected to the outflow drainage subpipe is defined as By ensuring that the rainwater that has flowed into the diversion outlet from the inlet / outlet port to which the inflow drainage pipe is connected, regardless of the amount of rain that can be drained from the reference outlet, It can be prevented that it directly flows into the connected inflow / outlet port.

  Further, it is preferable that an orifice is disposed at the reference outlet in the main body.

  By adopting such a configuration, it becomes possible to appropriately adjust the amount of rainwater drained from the reference outlet.

  Moreover, it is preferable that the said main body is a bottomed cylindrical shape.

  By adopting such a configuration, it becomes possible to arrange the plurality of inflow / outlet ports on the side wall of the main body in a well-balanced manner, and it is difficult for the drainage pipe piping design to become unreasonable.

  Furthermore, the present invention is a water diversion system comprising the above-mentioned diversion basin, wherein the inflow drainage pipe connected to one of the inflow / outflow ports of the diversion basin is directed from upstream to downstream. The water diversion system is characterized in that a downwardly inclined pipe gradient is set.

  By adopting such a configuration, it becomes possible to smoothly flow rainwater from the upstream to the downstream in the inflow drainage pipe that should most prevent the backflow of rainwater.

  In addition, the inflow drainage pipe connected to one of the outlet / outlet ports of the diverter is provided with a bent joint in which the end on the upstream side is located higher than the end on the downstream side. May be.

  Even with this configuration, it is possible to smoothly flow rainwater from upstream to downstream in the inflow drainage pipe that should most prevent backflow of rainwater.

  Further, the inflow drain pipe connected to one of the outlet / outlet ports of the diverter is provided with a bottomed cylindrical main body, and the downstream side opening and the downstream side of the main body side wall are provided. A drainage basin provided with an upstream opening having a lower end set at a position higher than a lower end of the side opening may be disposed.

  Even with this configuration, it is possible to smoothly flow rainwater from upstream to downstream in the inflow drainage pipe that should most prevent backflow of rainwater.

  Furthermore, a filter or a screen may be attached to the inflow / outlet port to which the outflow drainage sub-tube is connected among the outflow / inlet ports of the main body.

  When a filter or a screen is attached to the inflow / outlet port in this way, dust or the like can be prevented from flowing into the outflow drainage sub-pipe.

  The water diverter of the present invention has a plurality of inflow / outflow ports, and both the inflow and outflow drainage pipes can be connected to the outflow / inflow ports, so that the degree of freedom in piping design is increased. Extremely expensive. Moreover, the water diversion system of this invention has the advantage which can respond to various construction sites.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying a water diverter and a water diversion system using the water diverter according to the present invention will be described in detail below. In addition, this invention is not limited to the Example shown below, A design change is possible suitably.

  As shown in FIGS. 1a and 1b, the water diverter 1 is provided with a bottomed cylindrical main body 2 whose axial direction is substantially vertical. The main body 2 is preferably made of a resin that is easy to manufacture and process. For example, a hard vinyl chloride resin is particularly preferable because of its high strength.

  As shown in FIG. 1 a, a side wall of the main body 2 is provided with one reference outlet 5 and three inflow / outlets 6, 7, 8. Further, as shown in FIG. 1b, the lower ends of the plurality of inflow / outflow ports 6, 7, and 8 are set at a position higher than the lower end of the reference outflow port 5 in the main body 2, and the outflow / inflow ports 6 , 7 and 8 are arranged so as to have the same height. In the present embodiment, as shown in FIG. 1a, the first inflow / outlet port 6, the third inflow / outlet port 8, and the second inflow / outlet port are used clockwise with respect to the reference outflow port 5. Arranged in the order of the mouth 7.

  Further, in the main body 2, an orifice 20 is attached to the reference outlet 5, and the amount of drainage from the reference outlet 5 is adjusted. As the orifice 20, a known technique is preferably employed.

Next, a water diversion system 30 using the water diverter 1 will be described with reference to FIG.
As shown in FIG. 2, the water diversion system 30 of a present Example is comprised by the said water diverter 1, the gutter 111, the infiltration facility 112, and the drain pipes 15a-18a which connect these.

  An outflow drainage main pipe 15 a is connected to the reference outlet 5 of the water diverter 1 through a receiving portion 15 that is extended outward from the reference outlet 5. The outflow drainage main pipe 15 a is connected to the side groove 111. In addition, an inflow drain pipe 16 a is connected to the first inflow / outflow port 6 through a receiving port 16 that is extended outward from the first outflow / inflow port 6. Furthermore, an inflow drain pipe 18a is connected to the third outflow / inlet port 8 via a receiving port 18 that is extended outward from the third outflow / inlet port 8. Furthermore, an outflow drainage sub-pipe 17a is connected to the second outflow / inflow port 7 via a receiving port 17 that is extended outward from the second outflow / inflow port 7. The outflow drainage sub-pipe 17a is connected to the infiltration facility 112.

  Each of the bottoms of the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a, 18a at the position connected to the outflow / inlet ports 6, 7, 8 in the diversion basin 1 of the diversion system 30 described above, The outlet drain sub-pipe 17a and the inlet drain pipes 16a and 18a are disposed at the same position as the bottom of the outlet drain main pipe 15a at the position connected to the reference outlet 5. Arranged at height. In addition, a filter 22 is attached to the second inflow / outlet port 7 in the main body 2 in order to prevent dust and the like from entering the infiltration facility 112. The filter 22 may be a known screen.

  Furthermore, as shown in FIG. 3, the outflow drain sub-pipe 17a and the inflow drain pipes 16a, 18a connected to the outflow / inlet ports 6, 7, and 8 of the diverter 1 are respectively directed from upstream to downstream. Therefore, rainwater can flow stably without flowing back through the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a and 18a. Further, the inflow drain pipe 16a is provided with elbow joints 19 and 19 in which the upstream end is disposed at a position higher than the downstream end. Thus, by forming a head in the drainage path, rainwater can flow stably without flowing back through the inflow drainage pipe 16a. In addition, although the elbow joints 19 and 19 shown in FIG. 3 are used by connecting two elbow joints 19, the elbow joint 19 may be used alone. Further, the elbow joint 19 may be appropriately disposed in the inflow drain pipe 18a or the outflow drain sub pipe 17a, or may be disposed in the outflow drain main pipe 15a. Further, in place of the elbow joint 19, another bent joint may be used as appropriate.

  Further, as shown in FIG. 4, a drainage drain 24 is connected to the other end of the inflow drainage pipe 18 a connected to the water diverter 1. More specifically, the drainage basin 24 includes a bottomed cylindrical main body 25, and the side wall of the main body 25 has a downstream opening 26 and a position higher than the lower end of the downstream opening 26. An upstream opening 27 having a lower end is provided. The other end of the inflow drain pipe 18a is connected to the downstream opening 26. Even in such a configuration, since a drop is formed in the drainage path, rainwater can flow stably without flowing back through the inflow drainage pipe 18a. The drainage basin 24 may be appropriately disposed in the inflow drainage pipe 16a or the outflow drainage sub pipe 17a, or may be disposed in the outflow drainage main pipe 15a.

  As shown in FIGS. 2 to 4, in the water diversion system 30 using the water diverter 1 having the above-described configuration, rainwater is contained in the main body 2 of the distiller 1 through the inflow drain pipes 16 a and 18 a. Is first drained to the side groove 111 sequentially through the reference outlet 5. Since the orifice 20 is attached to the reference outlet 5, the amount of rainwater drained into the side groove 111 is appropriately adjusted.

  In addition, the amount of rainwater flowing into the diverter 1 through the drainage pipes 16a, 18a for inflow rather than the amount of rainwater flowing out from the reference outlet 5 into the gutter 111 in the diverter 1 due to an increase in water volume due to guerrilla heavy rain, etc. When the amount increases, the water is drained to the infiltration facility 112 through the second inflow / outlet port 7. Here, the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a and 18a are provided with pipe gradients, and the elbow joint 19 and drainage basin 24 are appropriately disposed. Smoothly flow down.

  As described above, the diverter 1 is provided with a plurality of inflow / outlet ports 6, 7, and 8 and the lower ends of the inflow / outlet ports 6, 7, and 8 are located in the main body 2 Since it is set at a position higher than the lower end of the reference outlet 5 and the outlet / outlet ports 6, 7, 8 are arranged at the same height, the outlet drainage sub-pipe 17 a according to the construction site. The inflow drain pipes 16a and 18a can be connected. Therefore, the use of the diverter 1 greatly improves the degree of design freedom when piping the drain pipes 16a to 18a. In addition, since the main body 2 of the diverter 1 has a circular shape in plan view, a plurality of inflow / outlets 6, 7, 8 are arranged on the side wall of the main body 2 in a well-balanced manner. Unreasonable in piping design.

  By the way, as shown in FIG. 1 and FIG. 2, in the diverter 1, the first inflow / outlet port 6 to which the inflow drain pipe 16a is connected and the outflow drain sub pipe 17a are connected. The second inflow / outlet port 7 is disposed so as to face. The separation distance D between the first inflow / outflow port 6 and the second inflow / outlet port 7 is such that D ≧ 3d with respect to the diameter d of the first inflow / outlet port 6 (see FIG. 1b). The length is set to meet. As described above, when the separation distance D is sufficiently secured with respect to the diameter d of the first inflow / outflow port 6, the first outflow / inflow portion can be used regardless of the amount of rain that can be drained from the reference outlet 5. There is no such a case that rainwater flowing in through the port 6 directly flows into the second inflow / outlet port 7.

  The water diversion system 30 is configured such that rainwater is drained to the side groove 111 via the reference outlet 5, but instead of the side groove 111, rainwater is drained to the rainwater main via the reference outlet 5. It may be configured. Further, the number of the inflow / outlet ports 6, 7, 8 disposed in the water diverter 1 can be appropriately changed. If there is an inflow / outlet port that is not used, a cap or the like that closes the opening is attached to the inflow / outlet port. In the water diversion system 30, the pipe gradient, the joint such as the elbow joint 19, or the drainage drain 24 is at least applied to the inflow drain pipes 16 a and 18 a that should prevent backflow most. It is often applied to the outflow drain pipes 15a and 17a as appropriate depending on the construction environment.
