[Problems to be Solved by the Invention] However, this method requires a lot of expense and travel time, making it difficult to train easily, and time differences affect physical condition. On the other hand, in order to build equipment on the ground that simulates the environment of high altitudes such as high mountains, the internal pressure is adjusted to the pressure equivalent to that of high altitudes, so it is necessary to build a solid structure that has the strength to withstand the difference in pressure from atmospheric pressure. In addition, maintaining the atmospheric pressure equivalent to the high altitude and controlling temperature and humidity require large-scale equipment, consuming a large amount of energy.

[0004] In view of the above circumstances, an object of the present invention is to provide an exercise structure that can be constructed at low cost, has an energy saving effect, is easy to maintain, and creates an environment equivalent to that of a highland.

It is an enlarged view of the attachment part.

As shown in FIG. 1, the exercise structure according to the present invention has an underground structure 1 in a bedrock 40. A cavity 2 is provided. The cavity 2 is provided with a horizontal bottom surface 2b at the bottom in the figure, and the bottom surface 2b is provided with a substantially elliptical ring-shaped track 31 on which an athlete can exercise, as shown in FIG. On the outer periphery of the track 31, a groove-shaped trench 22 is provided along the track 31, as shown in FIG. is bottom 2
A pool 30 in which athletes can swim is provided in the form of an excavated portion b, storing water 33. Further, as shown in FIG. 1, a waterproof sheet 20 is provided on the inner circumferential surface 40a of the upper part of the rock 40 in contact with the cavity 2 to cover the inner circumferential surface 40a, and the waterproof sheet 20 and the inner circumferential surface A gap space 7 is formed between 40a. The waterproof sheet 20 is made of rock 40
It is fixed to the rock 40 at predetermined intervals by a plurality of anchors 21 driven radially inside. However, at the openings of the tunnel 3 and the conduit 5, which will be described later, as shown by two-dot chain lines, the waterproof sheet 20 has openings so as not to obstruct the entry and exit of people, air, etc. Tarpaulin sheet 2
The end portion 20a of 0 is provided to collect underground water etc. seeping out from the rock 40 to the inner circumferential surface 40a into the trench 22, and the end portion 20a is provided to reduce the pressure between the cavity 2 and the gap space 7. are open to the cavity 2 so that they are equal. As shown in FIG. 3, the anchor 21 has a shaft-shaped anchor rod 25.
and two flat washers 26, 26 provided at one end of the anchor rod 25, and the other end of the anchor rod 25 is buried in a hole 28 drilled in a rock 40. Mortar 27 is placed in the space 28a of the hole 28.
It is fixed in a filled form. That is, the waterproof sheet 20
is fixed between two washers 26 and 26 of an anchor 21 fixed to a bedrock 40.

Furthermore, as shown in FIG. 1, a tunnel 3 is provided horizontally in the cavity 2 in a manner that connects the cavity 2 with the atmosphere 39 outside the rock 40 in the left-right direction in the figure. Space 3a of mine shaft 3
A pressure adjustment chamber 12 is provided in a manner that separates the inside of the cavity 2 from the atmosphere 39 and seals the cavity 2, and the pressure adjustment chamber 12 is
When a person enters and exits the cavity 2, the pressure inside the cavity 2 is not lowered,
Moreover, it is provided to eliminate the influence on the human body due to the pressure difference. Further, in the cavity 2, a conduit 5 is provided above the tunnel 3 in the left-right direction in the figure to connect the cavity 2 and the atmosphere 39, and at the end of the conduit 5 on the atmosphere 39 side, A blower 10 is provided which allows air to be evacuated through the space 5a of the conduit 5 and to control the air pressure within the cavity 2. Furthermore, the cavity 2 is equipped with an air conditioning device 1 that can control the temperature and humidity inside the cavity 2.
1 is provided.

[0012] Since the athletic structure according to the present invention has the above-mentioned configuration, when an athlete is training, the blower 10 is operated to exhaust the air in the cavity 2 through the conduit 5 to the atmosphere 39 side. , the pressure inside the cavity 2 is reduced and set to a predetermined atmospheric pressure. On the other hand, athletes and the like enter the cavity 2 through the tunnel 3. That is, one enters the tunnel 3 from the left side in FIG. 1, enters the pressure adjustment chamber 12 through the door on the atmosphere 39 side with the door on the cavity 2 side (not shown) of the pressure adjustment chamber 12 closed, and adjusts the physical condition to the predetermined pressure. Adapt. Next, while the door on the atmosphere 39 side is closed, open the door on the cavity 2 side to enter the cavity 2, and enter the atmosphere 39.
This prevents side air from flowing into the cavity 2 and increasing the air pressure inside the cavity 2. Therefore, by adjusting the physical condition of the athlete to the predetermined atmospheric pressure in the pressure adjustment chamber 12, even if the athlete moves into the cavity 2, the reduced atmospheric pressure will not affect the physical condition of the athlete or the like. Also, by alternately opening and closing the two doors (not shown), air from the atmosphere 39 side will not flow in.
The air pressure inside the cavity 2 is maintained at the predetermined air pressure. Furthermore, since the solid rock 40 bears the load caused by the pressure difference between the cavity 2 and the atmospheric pressure caused by reducing the pressure in the cavity 2, the cavity 2 can be constructed at a lower cost than when it is installed on the ground. Further, the temperature and humidity inside the cavity 2 are adjusted to predetermined values by the air conditioning device 11, but since the cavity 2 is provided in the rock, there are few changes in temperature and humidity throughout the year. That is, since the temperature underground is lower than the temperature in the atmosphere in the summer and higher than the temperature in the atmosphere in the winter, less energy is consumed for controlling the temperature and humidity inside the cavity 2. Furthermore, since the rock mass 40 has good airtightness, less energy is required for atmospheric pressure adjustment. Therefore, the energy required to maintain a predetermined atmospheric pressure and control the temperature and humidity inside the cavity 2 is more effective than when the cavity is provided above ground. Furthermore, the inner peripheral surface 40 of the cavity 2
A is covered with a waterproof sheet 20, and the waterproof sheet 20 blocks out groundwater seeping from the bedrock to the inner circumferential surface 40a and water condensing on the wall, collects the water in the trench 22, and drains it to the outside. Athletes can train comfortably because it doesn't rain, and maintenance is easy because exercise equipment such as the track 31 does not get wet.

In the above-mentioned embodiment, as shown in FIG. 1, an exercise structure was described in which a semi-spherical cavity 2 was connected to the atmosphere 39 through a horizontal tunnel 3. The shaft 3 may have any shape as long as exercise facilities such as a pool 30 and a track 31 can be provided therein, and the shaft 3 does not necessarily have to be provided horizontally. Moreover, the pool 30 and the trench 22 only need to be able to store and discharge water, and do not need to be provided by excavating the bottom surface 2b.
