The vacuum type sewage collecting device is configured to suck sewage and air into a pipeline by using the force of vacuum and transport them by the flow of air and gravity. Therefore, unlike a pressure type device that collects sewage from a liquid storage tank by pressurization, it is advantageous in that there is no sewage leakage due to pressure. Therefore, the importance of the vacuum type sewage collecting device is increasing not only as a conventional sewerage system but also as a drainage system in a building such as a building.
However, when trying to apply a vacuum sewage collector to a foundation seismic isolated structure building, problems can arise. For example, when the vacuum valve unit 10 designed on the premise of burying as described above is applied to a foundation seismic isolation structure having an isolator, for example, the following problems occur.

That is, when the vacuum type sewage collecting device is applied to a basic seismic isolation structure building, as shown in FIG. 9, the vacuum valve unit 10 in which the sewage is stored is set in the seismic isolation layer under the floor on the first floor (in other words, , Underground pit) 20 and a vacuum station 13 including a water collecting tank and the like may be installed in the building 19. However, when the conventional buried vacuum valve unit 10 is simply placed on the floor surface 21 of the seismic isolation layer 20, the pipes 12 and 14 fixed to the wall portion of the liquid storage tank 3 are connected to the seismic isolation joints 12a and 14a. It will be necessary to use the flexible structure used. In particular, for the pipe 14, a seismic isolation joint 14a having a negative pressure specification is required. Therefore, the material cost and the construction cost are relatively high. In addition, when maintaining the equipment, the worker needs to go down to the underground seismic isolation layer 20 to perform the work. Therefore, there is a problem that maintenance of the device is troublesome.

An object of the present invention is to provide a vacuum liquid transfer device that can be installed in a basic seismic isolation structure building at low cost. Another object of the present embodiment is to provide a vacuum liquid transfer device that is easy to maintain. Another object of the present embodiment is to provide a vacuum type liquid transfer device capable of preventing odor diffusion from a liquid storage tank.

According to one embodiment of the present invention, it is a vacuum type liquid transport device for transporting the liquid stored in the liquid storage tank to the liquid collection tank in the building by the negative pressure in the pipeline, and is a building.

Hereinafter, each embodiment of the present invention will be described with reference to the drawings. The following description is merely an example, and does not mean that the technical scope of the present invention is limited to the following embodiments. Further, in the drawings, the same or corresponding components are designated by the same reference numerals, and duplicate description will be omitted. In the following description, the terms indicating the directions such as "up" and "down" mean the directions in the installed state of the device shown in FIG. 1 and the like.

[First Embodiment]
FIG. 1 is a side sectional view schematically showing a configuration example of the vacuum liquid transfer device 100 according to the first embodiment of the present invention. The vacuum liquid transfer device 100 collects the liquid (in other words, drainage) discharged from the equipment 110 in the building 102 with respect to the building 102 having the basic seismic isolation structure, and discharges the liquid (exhaust liquid) to the outside (not shown). It is used to transport to a liquid treatment facility. Specifically, as shown in FIG. 1, the building 102 is supported by a seismic isolation device 106 such as an isolator in the seismic isolation layer 104. The internal space of the seismic isolation layer 104 is defined by the floor surface 104a and the side surface 104b. In the vacuum type liquid transfer device 100, the drainage liquid from the equipment 110 in the building 102 is stored in the liquid storage tank 108 arranged in the seismic isolation layer 104. However, the liquid storage tank 108 may store the drainage from the drainage facility outside the building 102. The drainage in the liquid storage tank 108 is collected in the liquid collection tank 112 installed in the building 102 by using the negative pressure in the pipeline (in other words, the vacuum pipe) 116.

As shown in FIG. 1, the drainage from each facility 110 in the building 102 passes through a drainage pipe (hereinafter, inflow pipe) 114 having an opening end in the liquid storage tank 108 and reaches the liquid storage tank 108. Inflow. The drainage liquid that has flowed into the liquid storage tank 108 is stored in the liquid storage tank 108 until a predetermined amount is reached. When the amount of drainage in the liquid storage tank 108 reaches a predetermined amount, the vacuum valve 122 (described later) opens, and the drainage is conveyed from the liquid storage tank 108 to the liquid collection tank 112 by the negative pressure in the pipeline 116. The liquid collecting tank 112 is installed on the floor surface 102a of the building 102. Negative pressure is introduced from the vacuum pump 118 into the gas phase portion of the liquid collection tank 112.

The vacuum liquid transfer device 100 of the first embodiment can include a liquid storage tank 108 and a pipe 120. The pipe 120 can form at least a part of the pipe line 116 from the liquid storage tank 108 to the liquid collection tank 112. The pipe 120 has an end that opens in the liquid storage tank 108. A vacuum valve controller (not shown), which will be described later, is attached to the vacuum valve 122.

In the first embodiment, the liquid storage tank 108 is installed on the floor surface 104a of the seismic isolation layer 104. However, if necessary, the liquid storage tank 108 may be fixed to the side surface 104b of the seismic isolation layer 104.

In FIG. 1, reference numeral 124 denotes a sensor tube 124 that detects the water level in the liquid storage tank 108. The sensor tube 124 is fluidly connected to a vacuum valve controller (not shown) attached to the vacuum valve 122. The sensor tube 124 has an end that opens in the liquid storage tank 108. The vacuum valve controller operates according to the water level detected by the sensor tube 124, and the vacuum valve 122 is opened and closed. The opening and closing of the vacuum valve 122 may be controlled by electrically combining a general water level sensor and a control device without using the combination of the sensor tube 124 and the vacuum valve controller. When the vacuum valve 122 is opened, a negative pressure is introduced into the pipe line 116 through the gas phase portion of the liquid collecting tank 112, and the drainage liquid in the liquid storage tank 108 is sucked toward the liquid collecting tank 112. The drainage collected in the liquid collection tank 112 is conveyed to the drainage treatment facility outside the building 102 through a pipeline (not shown) via the pressure feed pump 126.

The vacuum liquid transfer device 100 includes a support member 128 capable of supporting a pipe arranged in the liquid storage tank 108. As shown in FIG. 1, the support member 128 is fixed to the skeleton (in other words, the floor slab) of the building 102 above the liquid storage tank 108, and is provided so as to project from the skeleton into the seismic isolation layer 104. .. By fixing the pipe 120 and the sensor pipe 124 (hereinafter, also collectively referred to as pipes 120 and 124) to the support member 128, the pipes 120 and 124 are connected to the floor surface 104a (specifically, the liquid storage tank 108) of the seismic isolation layer 104. ) (In other words, it is not fixed to the liquid storage tank 108).

In the first embodiment, the support member 128 (shown in the side sectional view in FIG. 1) has a bottomed tubular shape, for example, a building using an appropriate mounting member such as an angle member. It can be fixed to the skeleton of 102. The cross-sectional shape of the bottomed tubular support member 128 is not particularly limited, and may be circular, rectangular, elliptical, or the like. In this case, the pipe 120 is passed through a through hole (reference numeral omitted) formed in the tubular side wall 128a of the support member 128 and the bottom wall 128b, and the sensor tube 124 is formed in the bottom wall 128b of the support member 128. It is passed through a through hole (reference numeral omitted) and suspended toward the liquid storage tank 108 (as will be described later, the liquid storage tank 108 has an upper surface opening 132 that receives pipes 120 and 124). The pipes 120 and 124 are fixed to and supported by the support member 128 through the through holes. In particular, since the bottomed tubular form of the support member 128 forms a closed space with respect to the space in the seismic isolation layer 104, the vacuum valve 122 and its accessory parts (hereinafter, vacuum valve 122 and the like) are contained therein. ) Can be stored. In the first embodiment, the operator can access the vacuum valve 122 and the like from inside the building 102 for maintenance through the inspection hole 130 described later. In this case, the bottomed tubular support member 128 prevents the operator from dropping the tool on the liquid storage tank 108, the floor surface 104a of the seismic isolation layer 104, or the like. Therefore, the operator can efficiently and easily perform the maintenance work.

However, the specific shape of the support member 128 is not limited to the above. For example, the support member 128 may have a ring shape capable of receiving the pipe 120 or the sensor pipe 124, respectively. Further, the support member 128 may have a hook shape. Further, the support member 128 is composed of, for example, a plate-shaped member on which the pipes 120 and 124 are placed directly or via a frame, and a rod-shaped member for suspending the plate-shaped member from the skeleton of the building 102. You may be.

Thus, in the first embodiment, the support member 128 allows the piping to be arranged in a non-fixed state with respect to the liquid storage tank 108 installed on the floor surface 104a of the seismic isolation layer 104. As a result, in the event of an earthquake, the pipes 120 and 124 can be insulated from the floor surface 104a of the seismic isolation layer 104, so that the shaking on the ground side is not directly transmitted to the pipes 120 and 124. Of the pipes 120 and 124, the pipe 120 particularly constitutes a part of the pipe line 116 leading to the liquid collecting tank 112 installed in the building 102. Therefore, as described with reference to FIG. 9, if the pipe 120 is fixed to the liquid storage tank 108 placed on the floor surface 104a of the seismic isolation layer 104, the relative displacement between the ground side and the building 102 side It is necessary to provide the pipe 120 with a seismic isolation joint for absorbing the above. However, in the first embodiment, the pipes 120 and 124 are integrated with the building 102 side in a state of being cut off from the ground side. Therefore, it is not necessary to provide the seismic isolation joint in the pipe 120. As a result, the material cost and the construction cost when installing the vacuum type liquid transfer device 100 can be reduced as compared with the case where the buried type vacuum valve unit 10 is used.

In the first embodiment, the pipe 120 and the sensor pipe 124 are each directly supported by the support member 128. However, depending on the specific configuration of the sensor tube 124, the support member 128 may not directly support the sensor tube 124. For example, the sensor pipe 124 may be integrally formed with the pipe 120. In that case, the pipe 120 is directly supported by the support member 128, and the sensor tube 124 is supported by the support member 128 via the pipe 120. Further, the support member 128 may be configured to support the inflow pipe 114 in addition to the pipe 120 and the sensor pipe 124.

The vacuum liquid transfer device 100 of the first embodiment includes a liquid storage tank 108 installed on the wall surface of the seismic isolation layer 104. Here, the “wall surface of the seismic isolation layer 104” means the floor surface 104a or the side surface 104b of the seismic isolation layer 104. In the example of FIG. 1, the liquid storage tank 108 is installed on the floor surface 104a of the seismic isolation layer 104. Further, "installed on the wall surface of the seismic isolation layer 104" does not necessarily mean that the liquid storage tank 108 comes into direct contact with the wall surface of the seismic isolation layer 104. That is, there may be a member that indirectly contacts the wall surface of the seismic isolation layer 104 and the liquid storage tank 108. In the example of FIG. 1, the liquid storage tank 108 may be placed on the floor surface 104a via an appropriate pedestal, pedestal, or the like.

As shown in FIG. 1, the liquid storage tank 108 has an open top opening 132 above it (in other words, toward the skeleton of the building 102). The upper surface opening 132 may be open to the space above the liquid storage tank 108, and its size and shape are not particularly limited. For example, the liquid storage tank 108 can have an upper surface opening 132 such as a circular shape, a rectangular shape, or an elliptical shape. In the illustrated example, the liquid storage tank 108 is formed so that its side wall 108a extends substantially linearly in the vertical direction. However, the side wall 108a of the liquid storage tank 108 may be bent inward at its upper end so as to form an upper wall, in which case the upper surface opening 132 is defined by the inner edge of the bent portion. Through the upper surface opening 132, the pipe 120, the sensor pipe 124, and the inflow pipe 114 can be received in the liquid storage tank 108 without contacting the wall of the liquid storage tank 108. In this case, like the pipe 120, the inflow pipe 114 also does not require a seismic isolation joint. The inflow pipe 114 is fixed to the skeleton so as to penetrate the skeleton of the building 102, and extends into the seismic isolation layer 104.

Further, in the first embodiment, since the upper surface opening 132 is open to the space in the seismic isolation layer 104, the air intake pipe (air intake in FIG. 7) required for the conventional embedded vacuum valve unit 10 is used. It is not necessary to provide tube 11). Further, by providing the upper surface opening 132, the material cost of the liquid storage tank 108 itself can be reduced.

In the event of an earthquake, the pipe 120, the sensor pipe 124, and the inflow pipe 114 are integrally displaced with the building 102 in the horizontal direction. Therefore, the liquid storage tank 108 is sized so that it does not come into contact with these pipes that are displaced in the horizontal direction during an earthquake.

In the first embodiment, the liquid storage tank 108 has a single upper surface opening 132, and the pipe 120, the sensor pipe 124, and the inflow pipe 114 are arranged in the single upper surface opening 132. However, the liquid storage tank 108 can have a plurality of top surface openings, and the pipe 120, the sensor pipe 124, and the inflow pipe 114 may be arranged in different top surface openings, respectively. In this case, the liquid storage tank 108 includes an upper wall in which a plurality of upper surface openings are formed.

Further, the vacuum type liquid transfer device 100 can include an inspection lid 134 provided so as to open and close an opening (in other words, an inspection hole) 130 provided in the skeleton of the building 102. The inspection hole 130 is formed at a position where the vacuum valve 122 and the like can be inspected when the inspection lid 134 is opened. In the first embodiment, the inspection hole 130 is opened inside the bottomed tubular support member 128. As a result, the worker can access the vacuum valve 122 and the like from the inside of the building 102. Therefore, the worker can easily perform the maintenance work without getting down into the seismic isolation layer 104. Further, as described above, the bottomed tubular support member 128 can prevent the tool dropped by the operator from falling into the seismic isolation layer 104 (specifically, in the liquid storage tank 108). it can.

In the first embodiment, the upper surface opening 132 of the liquid storage tank 108 is opened in the internal space of the seismic isolation layer 104. However, in the following modifications described with reference to FIGS. 2A-4, the vacuum liquid transfer device 100 can include a lid member having a circular outer shape that covers the circular upper surface opening of the liquid storage tank. The lid member has a through hole (reference numeral omitted) for inserting a pipe passing through the upper surface opening, and the pipe is fixed to the through hole.

2A and 2B are views for explaining the operation of the lid member, and are views showing a top view of the liquid storage tank 208 in which the lid member 221 is arranged in the upper surface opening 232 and a cross section thereof AA. The liquid storage tank 208 has an upper wall 208a defining an upper surface opening 232. For convenience of explanation, in FIGS. 2A and 2B, a single pipe (here, pipe 120 in FIG. 1) is arranged in a single upper surface opening 232 of the liquid storage tank 208, and the liquid storage tank 208 is a single. It has a lid member 221 of. However, in practice, as shown in FIG. 3 or 4, the liquid storage tank 208 takes at least air into the pipe 120, the sensor pipe 124 and the inflow pipe 114 shown in FIG. 1 and the liquid storage tank 208. An air intake pipe 225 for the purpose may be arranged. FIG. 3 shows four pipes in the four upper surface openings 232a, 232b, 232c, and 232d formed in the upper wall 208a of the liquid storage tank 208, that is, the sensor pipe 124, the pipe 120, the inflow pipe 114, and the air intake pipe 215. Indicates the case where is placed. The liquid storage tank 208 of FIG. 3 has four lid members 221a, 221b, 221c, and 221d fixed to the sensor pipe 124, the pipe 120, the inflow pipe 114, and the air intake pipe 215, respectively. FIG. 4 shows a case where the pipe 120, the sensor pipe 124, the inflow pipe 114, and the air intake pipe 215 are arranged in the single upper surface opening 232 of the liquid storage tank 208. The liquid storage tank 208 of FIG. 4 has a single lid member 221 having separate through holes (reference numerals omitted) into which the pipe 120, the sensor pipe 124, the inflow pipe 114, and the air intake pipe 215 are inserted and fixed. ing. In the top views of FIGS. 3 and 4, the positions of the pipes in the liquid storage tank 208 are not limited to those shown in the drawings. Further, if necessary, pipes other than the pipe 120, the sensor pipe 124, the inflow pipe 114, and the air intake pipe 215 may be arranged in the liquid storage tank 208.

Returning to FIG. 2B, the pipe 120 is positioned with respect to the liquid storage tank 208 so that its open end 120a is located at a predetermined height from the bottom surface of the liquid storage tank 208. The vertical position of the lid member 221 with respect to the pipe 120 is the height at which the upper surface opening 232 is closed when the pipe 120 is positioned with respect to the liquid storage tank 208 (in other words, the lid member 221 is above the liquid storage tank 208. The height of contact with the upper surface of the wall 208a) is set. The lid member 221 has a circular outer shape having an outer diameter larger than the diameter D of the upper surface opening 232. The lid member 221 is arranged in a non-fixed state with respect to the liquid storage tank 208. In other words, the lid member 221 is slidably arranged on the upper surface of the upper wall 208a of the liquid storage tank 208.

In this way, the lid member 221 can close the upper surface opening 232 of the liquid storage tank 208. Therefore, it is possible to prevent the odor generated by the drainage in the liquid storage tank 208 from diffusing into and out of the seismic isolation layer 104. Since the lid member 221 to which the pipe 120 is fixed is arranged in a non-fixed state with respect to the liquid storage tank 208, the lid member 221 can freely move in all directions in the horizontal plane at the time of an earthquake. Therefore, as in the first embodiment, it is not necessary to provide a seismic isolation joint in the pipe (here, the pipe 120). Since the circular lid member 221 has an outer diameter larger than the diameter D of the circular upper surface opening 232, the circular lid member 221 does not fall into the liquid storage tank 208 even if it moves during an earthquake.

In FIGS. 2A and 2B, the pipe 120 is fixed substantially in the center of the circular lid member 221 and is arranged so as to be substantially centered in the top opening 232. In this case, by setting the radius (D / 2) of the upper surface opening 232 to a size larger than the design horizontal displacement amount of the foundation seismic isolation structure building 102, the liquid storage tank even if the pipe 120 moves in the horizontal direction during an earthquake. It is possible to prevent contact with the wall of 208. This is particularly advantageous in the configuration of FIG.

Since the lid member 221 is fixed to the pipe 120, it is preferably made of a lightweight resin so that an excessive weight is not applied to the pipe 120.
[Second Embodiment]

Next, the vacuum liquid transfer device 300 according to the second embodiment will be described with reference to FIG. In the description of the second embodiment, the illustration and detailed description of the configuration common to the first embodiment will be omitted. The second embodiment is different from the first embodiment in that the liquid storage tank is suspended and supported by the frame of the building.

The vacuum liquid transfer device 300 of the second embodiment includes a liquid storage tank 308 for storing the liquid discharged from the equipment (not shown) in the building 302 through the inflow pipe 314. The liquid storage tank 308 has a bottomed tubular portion 308a that defines a storage space for storing the liquid, and a lid portion 308b that closes the storage space with respect to the space in the seismic isolation layer 304. The lid portion 308b is fixed to the upper end of the bottomed tubular portion 308a. The pipe 320, the sensor pipe 324, the inflow pipe 314, and the air intake pipe 325, which form a part of the vacuum pipe 316, are arranged in the storage space through a through hole (reference numeral omitted) formed in the lid portion 308b. The vacuum valve 322 and its accessories (for example, a vacuum valve controller (not shown)) (hereinafter, vacuum valve 322 and the like) are arranged outside the liquid storage tank 308.

Further, the vacuum liquid transfer device 300 of the second embodiment includes a support member 328 fixed to the skeleton of the building 302 so as to suspend and support the liquid storage tank 308. The support member 328 is fixed to the lid portion 308b of the liquid storage tank 308. However, the support member 328 may be fixed to the bottomed tubular portion 308a of the liquid storage tank 308.

Further, similarly to the first embodiment, the vacuum type liquid transfer device 300 of the second embodiment is provided with an opening (in other words, an inspection hole) 330 provided in the skeleton of the building 302 so as to be openable and closable. A lid 334 can be included. The inspection hole 330 is formed at a position where the vacuum valve 322 and the like can be inspected when the inspection lid 334 is opened. As a result, the worker can access the vacuum valve 322 and the like from the inside of the building 302. Therefore, the worker can easily perform the maintenance work without getting down into the seismic isolation layer 304.

In the illustrated example, the support member 328 is a plurality of rod-shaped members that can be fixed to the skeleton of the building 302 via an appropriate mounting member (only two rod-shaped members 328a and 328b are shown in FIG. 5). .. However, the specific shape and number of the support members 328 are not particularly limited. If the support member 328 is formed in a tubular shape that surrounds the vacuum valve 322 and the like between the frame of the building 302 and the lid portion 308b, for example, the operator can eliminate tools when performing maintenance work through the inspection hole 330. It is possible to prevent the floor surface 304a in the seismic layer 304 from being dropped.

Thus, in the second embodiment, the liquid storage tank 308 closed with respect to the space in the seismic isolation layer 304 is suspended from the skeleton of the building 302 into the seismic isolation layer 304 by the support member 328. Thereby, in the event of an earthquake, the liquid storage tank 308 can be insulated from the wall surface of the seismic isolation layer 304. Therefore, even if the pipe is fixed to the liquid storage tank 308, the shaking on the ground side is not directly transmitted to the pipe. Among the pipes, the pipe 320 particularly constitutes a part of the pipe line 316 leading to the liquid collecting tank (not shown in FIG. 5) installed in the building 302. Therefore, as described with reference to FIG. 9, if the pipe 320 is fixed to the liquid storage tank 308 placed on the floor surface 304a of the seismic isolation layer 304, the relative displacement between the ground side and the building 302 side It is necessary to provide the pipe 320 with a seismic isolation joint for absorbing the above. However, in the second embodiment, the liquid storage tank 308 is integrated with the building 302 side in a state of being cut off from the ground side. Therefore, it is not necessary to provide a seismic isolation joint in the pipe 320. Further, the seismic isolation joint is not required for the inflow pipe 314 extending from the equipment in the building 302. Thereby, the material cost and the construction cost when installing the vacuum type liquid transfer device 300 can be reduced as compared with the case where the buried type vacuum valve unit 10 is used.

Further, in the second embodiment, the liquid storage tank 308 is closed to the space in the seismic isolation layer 304 by the lid portion 308b. Therefore, the odor of the liquid in the liquid storage tank 308 does not diffuse into and out of the seismic isolation layer 304.
[Third Embodiment]

Next, the vacuum liquid transfer device 400 according to the third embodiment will be described with reference to FIG. In the description of the third embodiment, the illustration and detailed description of the configuration common to the first embodiment will be omitted. The third embodiment is different from the first embodiment in that the liquid storage tank 408 is suspended and supported by the skeleton of the building 402.

Further, the third embodiment is different from the second embodiment in that the liquid storage tank 408 is formed by the skeleton of the building 402 (in other words, it forms a part of the skeleton of the building 402). Is different. The liquid storage tank 408 of the third embodiment includes a liquid storage tank 408 that stores the liquid discharged from the equipment (not shown) in the building 402 through the inflow pipe 414.

The liquid storage tank 408 further has a partition wall portion 408c. The inside of the liquid storage tank 408 by the partition wall portion 408c is a storage chamber 410 for storing the liquid, a vacuum valve 422 provided in the pipe 420 forming a part of the vacuum pipe 416, and its accessory parts (for example, a vacuum valve (not shown)). It is partitioned into a storage chamber 412 in which a controller) (hereinafter, vacuum valve 422, etc.) is stored. The pipe 420, the sensor pipe 424, the inflow pipe 414, and the air intake pipe 425 are arranged in the liquid storage tank 408 so as to have an end that opens into the storage chamber 410. The pipe 420, the sensor pipe 424, the inflow pipe 414, and the air intake pipe 425 extend into the storage chamber 410 through through holes (reference numerals omitted) formed in the side wall 408a and / or the partition wall portion 408c.

Further, as in the first embodiment, the vacuum liquid transport device 400 of the third embodiment is provided with an opening (in other words, an inspection hole) 430 provided in the skeleton of the building 402 so as to be openable and closable. A lid 434 can be included. The inspection hole 430 is opened in the storage chamber 412. Therefore, when the inspection lid 434 is opened, the operator can inspect the vacuum valve 422 and the like through the inspection hole 430 from inside the building 402. Therefore, the worker can easily perform the maintenance work without getting down in the seismic isolation layer 404.

Thus, in the third embodiment, the liquid storage tank 408 is formed by the skeleton of the building 402. The liquid storage tank 402 projects in a suspended state in the seismic isolation layer 404. Thereby, in the event of an earthquake, the liquid storage tank 408 can be insulated from the wall surface of the seismic isolation layer 404. Therefore, even if the pipe is fixed to the liquid storage tank 408, the shaking on the ground side is not directly transmitted to the pipe. Of the pipes, the pipe 420 particularly constitutes a part of the pipe line 416 leading to the liquid collection tank (not shown in FIG. 6) installed in the building 402. Therefore, as described with reference to FIG. 9, if the pipe 420 is fixed to the liquid storage tank 408 placed on the floor surface 404a of the seismic isolation layer 404, the relative displacement between the ground side and the building 402 side It is necessary to provide a seismic isolation joint in the pipe 420 to absorb the water. However, in the third embodiment, the liquid storage tank 408 is integrated with the building 420 side in a state of being cut off from the ground side. Therefore, it is not necessary to provide the seismic isolation joint in the pipe 420. Further, the seismic isolation joint is not required for the inflow pipe 414 extending from the equipment in the building 402. Thereby, the material cost and the construction cost when installing the vacuum type liquid transfer device 400 can be reduced as compared with the case where the buried type vacuum valve unit 10 is used.

Further, in the third embodiment, the bottomed tubular liquid storage tank 408 is closed with respect to the space in the seismic isolation layer 404. Therefore, the odor of the liquid in the liquid storage tank 408 does not diffuse into and out of the seismic isolation layer 404.
