[Prior Art]

 The temperature changes in the ground and groundwater are small throughout the year, so there is a temperature difference between the temperature and the temperature, which changes greatly according to the four seasons. In other words, the underground temperature is lower than the temperature in the summer and warm in the winter.In both seasons, heat exchange between the ground and the ground is performed to reduce the heating and cooling costs. You can Such attempts have been made for a long time, and various devices have been developed. For example, "air conditioners utilizing underground temperature", such as those in Japanese Utility Model Publication No. 58-16818, Japanese Utility Model Publication No. 58-16822, Japanese Utility Model Publication No. 58-16823, and Japanese Utility Model Publication No. 58-16824, and A "air conditioner using groundwater" according to Kaisho 58-16853 is known.

By the way, these devices have a heat transfer tube, the heat transfer tube is buried in the ground substantially vertically, and a liquid is caused to flow in the heat transfer tube to exchange heat. However, in order to perform air conditioning in a large building, since the heat capacity of one heat transfer tube is insufficient, many heat transfer tubes must be buried, which results in a significant increase in construction costs. Therefore, it has not been put to practical use in reality.

[0004]

 FIG. 1 is an embodiment showing a partition plate with an intake / drainage pipe of the present invention, wherein 1 is a partition plate, 2 is an intake pipe, and 3 is a drainage pipe. This embodiment is a partition plate with a water intake / drain pipe used for a heat exchange pile of a snow melting device. The water intake pipe 2 has a water intake port 4 projecting shortly from the lower surface of the partition plate 1, and a socket 5 on the upper surface side. It is connected through and extends for a predetermined length. This length is the length required to reach almost the upper end of the foundation pile when the partition plate is attached to the hollow portion of the foundation pile, and the projection length on the upper surface side of the drainage pipe 3 is also the same. Is becoming However, the drain pipe 3 is a pipe that releases heat and discharges the cooled heat exchange liquid, and therefore has a length that can reach the vicinity of the bottom of the hollow portion of the foundation pile. In order to attach the partition plate 1 to the hollow portion of the foundation pile, the partition plate 1 forms a disk having a size corresponding to the inner diameter of the hollow portion, and concave cutouts 6, 6 ... Are formed on the outer periphery thereof. The notch is formed and is engaged with a partition plate fixing metal member that is provided so as to project from the inner peripheral surface of the hollow portion, which will be described later.

FIG. 2 shows the partition plate with the intake / drainage pipe attached to the hollow portion 8 of the foundation pile 7, but the partition plate fixing metal fittings 9, 9, ... As shown in FIG. It partially projects from the inner peripheral surface 10 and is embedded in the foundation pile 7. The partition plate fixing fittings 9, 9 ... Are provided at positions corresponding to the positions of the notches 6, 6 ... of the partition plate 1, and the partition plate 1 is fitted through the notches 6, 6 ... , And rotate it by a certain angle to shift the positions of the notches 6, 6 from the positions of the partition plate fixing metal fittings 9, 9 and attach them. The partition plate fixing metal fittings 9, 9 ... Are provided at a plurality of places at predetermined intervals, and the partition plate 1 is attached by appropriately selecting its height. The partition plate 1 attached to the partition plate fixing brackets 9, 9 is provided with a seal 11 around the partition plate 1 to eliminate a gap generated between the partition plate 1 and the inner peripheral surface 10. By the way, below the partition plate 1, the heat exchange liquid 12 is filled up to the vicinity of the partition plate 1, the intake port 4 of the water intake pipe 2 is near the water surface of the heat exchange liquid 12, and the drain pipe 3 extends largely downward. ing.

FIG. 3 shows another embodiment of the present invention, and the shape of the partition plate with the intake / drain pipe is different from that of the above embodiment. In this embodiment, as shown in the figure, the partition plate fixing metal fittings 9, 9, ... Are not provided in the hollow portion 8 of the foundation pile 7, and the partition plate with the intake / drain pipe is suspended by the suspenders 13. ing. The hanger 13 is welded to the peripheral portion of the partition plate 1, extends upward, and forms a key shape bent into an L-shape at the upper end, and is locked to the upper end surface of the foundation pile 7 to form a partition with a drainage pipe. Suspend the plate to a given height. Of course, the intake pipe 2 and the drain pipe 3 extending upward and downward from the partition plate 1 are the same as those in the above embodiment.

4A to 4E are schematic views showing a foundation concrete placing process after a partition plate with a drainage pipe is attached to the foundation pile 7 driven into the ground, and the foundation pile 7 is a pile. It is buried from the ground (GL) to a predetermined depth (about several meters) by a driving machine. In this case, the cap 14 is covered in advance so that soil and mud do not enter the hollow portion 8 of the foundation pile 7. (Fig. 4a). Then, the concrete is excavated to the bottom surface 15 where the concrete is placed, after which the cap 14 is removed and the partition plate with the drainage pipe is attached. (Fig. 4c). A seal 11 is provided around the partition plate 1 of the partition plate with intake and drainage pipes to seal the space between the partition plate 1 and the inner peripheral surface 10 of the hollow portion (Fig. 4d). Further, as shown in FIG. 4e, the foundation concrete 16 is cast to a predetermined height on the foundation bottom surface 15. In this case, another pipe is connected to the intake pipe 2 and the drainage pipe 3 via the socket 5, The connecting pipe projects from the concrete foundation 16 to the upper surface. However, the present invention does not limit where and how to use these connecting pipes.

Here, when the foundation pile 7 cannot be driven to a predetermined depth from the ground (GL), the upper end of the foundation pile 7 is cut as usual. In addition, in the driving process shown in FIG. 4, the partition plate with the intake / drainage pipe is attached to the hollow part 8 after the driving is completed, but it may be attached before the driving process without any problem, and rather, a plurality of partition plates may be attached. When it is necessary to connect the foundation piles 7 of the book and bury them deeply, a large buoyant force acts on the foundation piles 7, so that the hollow portion 8 is heated by using the intake and drain pipes 2 and 3. By adding the exchange liquid 12, the above buoyancy can be suppressed. As described above, the following effects can be obtained by constructing the partition plate with the intake / drain pipe of the heat exchange foundation pile as described above.
