Description

  The present invention relates to a non-gradient drainage system, such as siphon drainage, forced drainage (pumping), vacuum (vacuum) drainage, and the like, which has a non-gradient part arranged along a floor slab with no gradient, and the non-gradient drainage. The present invention relates to a pipe drainage system used for the above.

  In recent years, non-gradient drainage systems such as siphon drainage, forced drainage (pressure feed), and vacuum (vacuum) drainage have been proposed in place of conventional gradient drainage systems. This non-gradient drainage system has a non-gradient part arranged non-gradient along the floor slab, and drainage that promotes drainage by applying a downstream force to the drainage in the non-gradient part. System. Among these, for example, as described in Patent Document 1, a siphon drainage system is composed of a watering device and a siphon drainage pipe, and a siphon force generated by a soot pipe that forms a hanging part of the siphon drainage pipe. (Negative pressure) is a system that improves drainage efficiency from watering devices.

  In such a non-gradient drainage system, compared with the conventional gradient drainage system, since the gradient is not required for the horizontal pulling pipe on the floor slab, the horizontal pulling pipe can be lengthened. On the other hand, in the conventional gradient drainage system, a gradient is necessary, and when trying to fit within the predetermined underfloor dimensions, the horizontal branch pipe is about 2 to 3 m from the watering device even if it is long. The underfloor dimensions had to be increased.

  In this way, in the non-gradient drainage system, the horizontal pipe can be lengthened, so there is no need to install a drainage stack near the watering device, and the merit that the degree of freedom of design can be increased, In the case of an apartment house, there is an advantage that maintenance and renewal can be facilitated by installing a drainage stack in a common part.

  By the way, it may be necessary to replace the drain pipe itself due to blockage in the drain pipe, deterioration or damage of the drain pipe, and the like. In this case, when exchanging the drain pipe, a method and a configuration suitable for a non-gradient drain system are required.

For example, as shown in FIG. 5, the side branch pipe P0 in the conventional gradient drainage system is dispersedly connected to the plurality of drainage stacks H0, and therefore, when the drainage pipe is replaced, the floor in the region E0 is removed. Thus, the horizontal pulling tube P0 can be replaced. However, since the horizontal pipe P1 in the non-gradient drainage system normally pipes up to the MB facing the open corridor, as shown in FIG. 6, if the floor of the area E1 is not removed, the horizontal pipe P1 is replaced. Can not do it.

  The present invention has been made in view of the above-described facts, and an object thereof is to provide a non-gradient drainage system capable of easily exchanging pipes and a pipe maintenance method in the non-gradient system.

  The gradient-free drainage system according to claim 1 of the present invention has a gradient-free portion arranged without gradient, and promotes drainage by applying a downstream force to the drainage in the gradient-free portion. A gradient drainage pipe, and a spare drainage pipe that includes at least a pipe portion corresponding to the no-gradient part and is disposed along the no-gradient drain pipe without being connected to a drainage path.

  The non-gradient drainage system of the present invention is provided with a spare drainage pipe. The spare pipe has at least a portion corresponding to the non-gradient portion, but even a portion corresponding to the non-gradient portion has both a portion corresponding to the non-gradient portion and a portion arranged in the vertical direction. It may be.

  Here, the non-gradient does not necessarily need to be in the horizontal direction, and includes those having a slight level difference or gradient along the floor slab or ceiling.

  The spare piping is not connected to the drainage path. The drainage path and non-connection means that drainage does not flow in. When both ends are not connected to the drainage path, or the downstream end is connected to the drainage path, but the upstream end is the drainage path. If not connected to, etc.

  If a problem arises in the non-gradient pipe in use and it is necessary to replace it, a spare pipe may be connected to the drainage path instead of the non-gradient pipe. Therefore, the opening space for the work only needs to be a part necessary for exchanging the connection, and the pipe can be easily exchanged. If an inspection port is provided on the floor as the opening for this work, work such as peeling off the floor is not necessary, and replacement can be performed more easily.

  The non-gradient drainage system according to claim 2 of the present invention is characterized in that the spare drainage pipe has an end opening closed with a closing lid.

  In this manner, by closing the end opening of the spare pipe with the closing lid, foreign matter does not enter the spare pipe and can be kept in a good state. Further, both ends of the spare pipe are protected by the lid, and damage to the spare pipe end can be prevented.

  The non-gradient drainage system according to claim 3 of the present invention is characterized in that the non-gradient pipe is a siphon drain pipe, and siphon force is applied to promote drainage of the non-gradient part.

  Moreover, the non-gradient drainage system of Claim 4 of this invention is equipped with the storage tank which stores temporarily the waste_water | drain from several watering apparatus, The said siphon drain pipe and a spare drain pipe are the downstream of the said storage tank. It is arranged in that.

  Further, in the non-gradient drainage system according to claim 5 of the present invention, a storage space for storing the wastewater inside the storage tank is partitioned into a plurality of individual storage units by a partition member, and each of the plurality of individual storage units is divided. The drain pipe from the corresponding watering device and the siphon drain pipe are connected.

  Such a spare pipe can be suitably used for a siphon drainage system, and in particular, can be suitably used for a siphon drainage system including a storage tank.

  A pipe maintenance method according to a sixth aspect of the present invention is a pipe maintenance method used in the non-gradient drainage system according to any one of the first to fifth aspects, wherein the spare pipe is replaced with the non-gradient. It connects with the said drainage channel instead of a drainage pipe, It is characterized by the above-mentioned.

  According to the pipe maintenance method of the present invention, the spare pipe arranged along the non-gradient drain pipe is connected to the drainage channel instead of the non-gradient drain pipe, so that the pipe can be easily replaced.

  The pipe maintenance method according to claim 7 of the present invention is characterized in that the non-gradient drain pipes corresponding to a plurality of different watering devices are exchanged including the spare drain pipes.

  Depending on the amount of drainage from the watering device and the frequency of use, the gradient of the non-gradient drainage pipe may vary. For example, in siphon drainage pipes, pipes connected to a wash surface with less stagnation are less frequently drained by siphon force, so the inner wall of the pipes may not be washed by self-cleaning. . Thus, the non-gradient drain pipes can be evenly washed by exchanging the non-gradient drain pipes including the spare pipes.

  The pipe maintenance method according to claim 8 of the present invention is characterized in that the opening of the non-gradient drain pipe that is disconnected from the drainage channel by the replacement is closed with a closing lid.

  Thus, odor can be prevented by closing the non-gradient drain pipe opening after replacement.

  In the present invention, since the spare pipe is provided as described above, the pipe can be easily replaced.

  Embodiments according to the present invention will be described below with reference to the drawings.

  In this embodiment, a temporary storage type siphon drainage system will be described as an example of a non-gradient drainage system. In addition, the non-gradient drainage system and the pipe maintenance method of the present invention can be applied to other non-gradient drainage systems, and can also be applied to siphon drainage systems other than the temporary storage system. First, the overall configuration of the siphon drainage system according to the present embodiment will be described. FIG. 1 is a schematic view showing the overall configuration of the siphon drainage system according to the present embodiment.

  A siphon drainage system 10 according to the present embodiment is a drainage system that efficiently drains drainage from a watering device using siphon force.

  The siphon drainage system 10 of this embodiment is mainly used in an apartment house composed of a plurality of floors. In this embodiment, an example in which the siphon drainage system is used for an apartment house composed of a plurality of floors will be described. The siphon drainage system is preferably used for an apartment house, but can also be used for a detached house or a factory other than the apartment house.

  As shown in FIG. 1, the siphon drainage system 10 includes a drainage stack 12 that allows drainage to flow downward. The drainage stack 12 extends in the vertical direction (longitudinal direction) of the apartment house, and penetrates the floor slab 14 on each floor of the apartment house.

  A plurality of watering devices 16 are provided in each door of each floor of the apartment house, and one end of a drain introduction pipe 18 through which drainage discharged from the watering device 16 flows is connected to each watering device 16. ing. The other end of the drainage introduction pipe 18 is connected to the storage tank 50. The drainage introduction pipe 18 is disposed with a gradient so that the storage tank 50 side is lowered.

  The storage tank 50 is for temporarily storing drainage from the watering device 16. As shown in FIG. 2, a storage space 52 is configured inside the storage tank 50. The storage space 52 is partitioned into three individual storage portions 52A, 52B, and 52C by a partition member 54. The plurality of drainage introduction pipes 18A to 18C from the watering device 16 described above are respectively connected to the individual reservoirs 52A, 52B, and 52C.

  The individual storage parts 52A, 52B, 52C of the storage tank 50 are provided with connection parts 51A, 51B, 51C, and siphon drain pipes 22A, 22B, 22C (collectively referred to as “siphon drain pipe 22”). It is connected. The connection parts 51A, 51B, 51C have the same connection shape, and any of the siphon drain pipes 22A, 22B, 22C can be connected.

  As shown in FIG. 1, the siphon drain pipe 22 includes a horizontal pulling pipe 24 disposed along the floor slab 14, and a soot pipe 26 communicating with the horizontal pulling pipe 24. The horizontal pulling pipe 24 communicates with the storage tank 50 and is disposed on the floor slab 14 with no gradient in the horizontal direction. The soot pipe 26 communicating with the horizontal pulling pipe 24 is disposed in the vertical direction (vertical direction) along the drainage stack 12. The soot pipe 26 is connected to the drainage stack 12 through a junction joint 40. The junction joint 40 joins the drainage from the soot pipe 26 to the drainage stack 12.

  The horizontal pulling pipe 24 and the vertical pipe 26 are constituted by continuous drainage pipes without joining with other drainage pipes up to the junction part joint 40, and lead the drainage to the drainage stack 12. Further, the inner diameter of the horizontal pulling pipe 24 and the dredging pipe 26 is set so that the drainage flows in a full flow. A siphon force in the direction of drainage is applied to the drainage in the horizontal pipe 24 by the energy of the siphon head Hs.

  As shown in FIG. 1, a vent pipe 30 is further connected to the storage tank 50. The vent pipe 30 is connected to the drainage stack 12 via the junction joint 40.

  The siphon drainage system 10 is provided with a spare pipe 62. The spare pipe 62 includes a horizontal pulling spare pipe 64 disposed along the horizontal pulling pipe 24 and a soot spare pipe 66 disposed along the soot pipe 26. The spare pipe 62 is closed at the upstream end by the closing lid 65, and is connected to the junction joint 40 at the downstream end. The closing lid 65 is attached so as to cover the outer peripheral surface of the upstream end of the spare pipe 62. In this way, by closing the lid with the closing lid 65, it is possible to prevent foreign matter from entering the spare pipe 62. Further, since the outer peripheral end portion of the spare pipe 62 is covered with the closing lid 65, the outer peripheral end portion can be protected, and damage or the like can be prevented. The spare pipe 62 is the same pipe as the siphon drain pipe 22, and can be connected to the connection portions 51 </ b> A to 51 </ b> C of the storage tank 50 instead of the siphon drain pipe 22.

  In the siphon drainage system 10 having the above-described configuration, when the siphon drain pipe 22 needs to be replaced due to blockage, deterioration, damage, etc., the connection between the siphon drain pipe 22 and the spare pipe 62 may be exchanged. . For example, when exchanging the siphon drain pipe 22C and the spare pipe 62, the flooring near the upper portion of the storage tank 50 is removed, and the siphon drain pipe 22C is removed from the connection portion 51C. Then, the closing lid 65 of the spare pipe 62 is removed and attached to the connecting portion 51C.

  If an inspection port that can be opened and closed is provided in the upper part of the storage tank 50 in advance, it is not necessary to remove the floor, and replacement can be performed with a simpler operation.

  After the replacement, the opening of the siphon drain pipe 22 </ b> C that is disconnected is closed with a closing lid 65. Thus, odor can be prevented by closing the opening of the drain pipe after replacement.

  According to this embodiment, the opening for operation | work at the time of replacing | exchanging the siphon drain pipe 22 can be made small, and replacement | exchange operation | work can be performed easily.

  The siphon drain pipe 22 can be exchanged in this way because the siphon drain pipe 22 is constituted by a continuous drain pipe and the junction joint 40 is not joined with other drain pipes. . In a conventional gradient drainage system, since a plurality of drainage pipes are usually joined before reaching the drainage standpipe, replacement work is also required for the connection part with other drainage pipes. Thus, it is difficult to easily replace the drain pipe.

  Another reason why the siphon drain pipe 22 can be replaced is a non-gradient pipe. In the conventional gradient drainage system, a predetermined gradient is necessary for the spare pipe after replacement, and the pipe becomes difficult.

  Further, during maintenance, the connections of the siphon drain pipes 22A to 22C and the spare pipe 62 are exchanged and exchanged. This is so-called rotation. For example, as shown in FIG. 3, the siphon drain pipe 22A is connected to the connection part 51B, the siphon drain pipe 22B is connected to the connection part 51C, the spare pipe 62 is connected to the connection part 51A, and the siphon drain pipe 22C is not connected. Use pipes.

  At this time, the replacement of the siphon drain pipe 22 is performed by replacing the siphon drain pipe corresponding to a water purifier with a large reservoir such as a bathtub room drain and the siphon drain pipe corresponding to a water purifier having a small drainage amount such as a wash basin. It is preferable to do. In the siphon drainage system, the inner wall of the pipe can be cleaned by draining with siphon force. However, siphon drainage pipes that are compatible with watering devices with a small amount of drainage are difficult to drain due to the siphon effect. It is difficult to clean the inner wall of the house. Therefore, in order to uniformly clean the inner wall of the pipe, the siphon drain pipe having a large drainage amount and the siphon drain pipe having a small drainage amount are exchanged at the time of maintenance.

  In the present embodiment, the spare piping 62 including the horizontal pulling spare pipe 64 and the dredging spare pipe 66 is used. However, the dredging spare pipe 66 is not always necessary, and as shown in FIG. It is good also as the spare piping 61 of only the pulling spare piping 64 part. In this case, both ends of the spare pipe 61 are closed with the closing lid 65. Then, the upper end side of the spare pipe 61 may be connected to the connecting portion 51 of the storage tank 50 and the downstream end may be connected to the soot pipe 26.

  In this embodiment, one spare pipe is installed. However, a plurality of spare pipes may be installed or the same number of siphon drain pipes 22 may be installed.

  Moreover, although the siphon drainage system provided with the storage tank 50 was demonstrated in this embodiment, this invention is not provided with the storage tank 50, and the siphon drainage in which the siphon drain pipe 22 is directly connected to the drain pipe of the watering device 16. It can also be applied to the system.
