The cross-sectional view which shows the outline of the semi-underground agricultural house which concerns on this invention. The plan sectional view which shows the outline of the semi-underground agricultural house which concerns on this invention.

The agricultural greenhouse according to the present invention is a large semi-underground type plant cultivation having a width of about 6 m to 7 m, a length of about 50 m to 60 m, and a height inside the house of about 2.5 m to 3.5 m. House.

As shown in FIGS. 1 and 2, this agricultural house is a semi-underground agricultural house 10 having a floor surface 29 lower than the ground surface 37 by about 1.2 m to 1.8 m. The height from the floor surface 29 to the central portion of the ceiling 21 is about 2.5 m to 3.5 m.

The floor will be a block floor with tuff blocks 43 such as Oya stone, and the underground wall will be a stone wall 41 with plaster or the like on the block walls with tuff blocks 43 stacked. The front wall 25 is provided with an entrance / exit 26 (see FIG. 3) as appropriate, and a staircase 31 that descends to the floor surface 29 in the house.

As the block 43, for example, a block 43 of Oya stone having a thickness of about 15 cm, a width of about 30 cm, and a length of about 90 cm is laid or stacked, and a block floor with a thickness of about 15 cm or a block wall with a thickness of about 15 cm is used. Is to build.

In this floor, a stone debris floor layer is formed by laying 49 cm of tuffstone cutting powder, debris, etc. under the block floor by about 30 cm to 50 cm, and a cold / hot water pipe 59 is arranged on the upper surface of the debris floor layer. A block 43 of tuff stone is spread over the floor surface 29, and a cold / hot water pipe 59 is arranged inside the block 43.

Furthermore, a cold / hot water pipe 59 is also placed on the inner surface of the block wall, and plaster, clay, etc. are added to the cutting powder and debris of tuff rock to fill the cold / hot water pipe 59. A wall 45 is formed, and a cold / hot water pipe 59 is embedded in a wall body 41 composed of a block wall formed by a block 43 and a plastered wall 45.

When forming the wall 41, the excavated ground 35 is covered with 49 tuff stone cutting powder and debris to form the foundation of the floor, and the outer part of the wall 41 is also covered with tuff stone cutting powder. A tuff stone debris layer is formed on the outside of the wall 41 by the tuff block 43 so as to be filled with debris 49, and the thickness of the entire tuff stone is made thicker than the thickness of the block 43 itself. Is.

Then, as shown in FIG. 1, the wall body 41 as the stone wall on the front wall 25 side and the wall body 41 as the stone wall on the back wall 27 side have a height up to the ground surface 37, as shown in FIG. The wall 41 on the side wall 23 side is about 30 cm to 50 cm higher than the ground surface 37, and a heat insulating material layer 19 made of a heat insulating material is formed on the outer surface side of the wall 41 above the ground surface 37. Is.

In this way, the agricultural house 10 using tuff stone for the stone wall where the floor surface 29 is lowered by about 1.2 m to 1.8 m from the ground surface 37 to form the floor surface 29 and the wall body 41 of the underground part is tuff rock. Has a large number of voids of about 10 μm inside, and has water absorption even if it is slight. When the ambient temperature such as air temperature drops, the water content increases without causing water droplets on the surface, and the ambient temperature rises. When it rises, it vaporizes the water contained in the rock to reduce the rise in rock temperature, and by exhibiting constant temperature with little temperature change with respect to the ambient temperature, the constant temperature of the floor and the lower part of the wall surface makes it possible during the day and night. The temperature difference can be reduced.

In addition, tuff has a smaller heat transfer coefficient than metals and plastics and is similar to wood, and it is possible to reduce the temperature change of the floor and wall 41 in the house with respect to the ambient temperature change. When a temperature difference between the space and the wall 41 occurs, cold air and warm air can be radiated into the house by radiant heat to reduce the temperature change in the house.

For this reason, in this agricultural house 10, in combination with the geothermal heat of the earth 35, the temperature inside the house is reduced in winter when the temperature of the outside air is low, and it is warm, and in the summer when the temperature of the outside air is high, the inside of the house is warm. It is possible to reduce the rise in temperature and make it difficult for abnormally high temperatures in the house to occur even when the temperature rises unexpectedly, especially during the daytime in summer.

Further, as shown in FIGS. 1 to 3, the above-ground portion of the agricultural house 10 has columns 11 which are rod-shaped bodies having a length of about 1 m to 2 m and are erected at the positions of the left and right side walls 23, respectively. The upper ends of the columns 11 are connected to each other by a chevron or curved roof bone 13, and the columns 11 on the right side wall 23, the columns 11 on the left side wall 23, and the roof bones 13 are connected to each other. It connects at 15 to form a house skeleton.

Then, a vinyl sheet 17 is attached to this house frame to make a vinyl house, or a greenhouse with a transparent plate such as a transparent acrylic plate or a glass plate attached to the house frame is the same as a cultivation house for general agricultural products. The underground part of the right side wall 23, the left side wall 23, the front wall 25 and the back wall 27, which are the end faces, at least the ground surface 37 or less, is a wall body 41 made of tuff stone walls. is there.

Further, in this semi-underground agricultural house 10, a vinyl sheet isolation wall 51 extending from the ceiling 21 to the floor surface 29 is provided in parallel with the back wall 27 with the same width as the back wall 27, and the back wall 27 to 0. The intake chamber 53, which has a depth width of about 9 m to 1.8 m, is formed so as to be partitioned in the house.

The lower end of the isolation wall 51 provided in the immediate vicinity of the back wall 27 and parallel to the back wall 27 shall be fixed to the case and the floor surface 29 of the radiator panel 61, and the space in the house and the air intake chamber 53 via the radiator panel 61. It is designed to allow ventilation by communicating with the space of.

The radiator panel 61 has a flow path pipe having a large number of fins on the panel surface, and allows ventilation between the front side and the back side of the panel surface so as to pass through the gaps between the flow path pipes and the fins. It enables heat exchange between the air passing through the air flow path and the liquid passing through the flow path pipe.

An intake opening 55 that communicates the intake chamber 53 with the outside of the agricultural house 10 is provided above the back wall 27, and an exhaust port 57 provided with a ventilation fan 63 near the front wall 25 of the ceiling 21. Is provided.

Therefore, in this agricultural house 10, when the ventilation fan 63 is driven, the outside air is sucked into the intake chamber 53 from the intake opening 55, and the inside of the intake chamber 53 from the ceiling 21 to the floor surface 29 is lowered from above to below. The air below the intake chamber 53 can be drawn into the space inside the house through the radiator panel 61, and the air in the space inside the house can be discharged from the exhaust port 57.

The ventilation fan 63 gradually discharges the air inside the house to the outside of the house by rotating at a low speed, but a large fan is used to secure a large amount of discharge, and the air inside the house is slowly and surely discharged. It is designed so that it can be replaced.

In addition, by arranging a blower fan 65 at an appropriate place in the house space and stirring the air in the house space, the air in the corners of the house space where the air flow is small and the air tends to stagnate flows. This is to prevent the air whose temperature has risen from accumulating in the space inside the house and to ensure that the air is discharged from the exhaust port 57 so that the hot air does not stay in the agricultural house 10.

In this semi-underground agricultural house 10, the stone wall 41 on the back wall 27 side, the stone wall 41 on the left and right side walls 23, and the front wall 25 side excluding the entrance 26 part. A wall sprinkler pipe 79 is placed on the wall body 41 which is a stone wall of the above, and a wall sprinkler pipe 79 is provided so as to surround the circumference of the agricultural house 10 along the side wall of the agricultural house 10 and the inside of the end face. It is possible to moisten the wall 41 by spraying water on the front wall 25, the left and right side walls 23, and the wall 41 which is the lower part of the back wall 27.

The wall sprinkler pipe 79 is not limited to the upper end of the wall body 41 as shown in the drawing, but is the upper end so that almost the entire wall body 41 can be moistened, such as near the upper end of the inner side surface of the wall body 41. It suffices to arrange it in the vicinity.

In addition, several floor sprinkler pipes 77 are arranged on the floor surface 29 in parallel with the vertical direction in the house, and it is possible to sprinkle water on the floor surface 29 to moisten the floor surface 29. ..

Then, groundwater from a well (not shown), river water from a river, cold drainage from a factory, and other well water having a temperature lower than the temperature can be supplied to the wall sprinkler pipe 79, the floor sprinkler pipe 77, and the radiator panel 61. It is a thing.

As shown in FIG. 1, the water supply pipe 71 having a pump 91 is arranged in the floor surface 29, and the well water or the like is sent to the radiator panel 61 by the water supply pipe 71. A drain pipe 73 that returns well water or the like that has passed through the radiator panel 61 to a well or a river is also provided in the floor surface 29.

Further, the drainage pipe 73 is provided with a drainage on-off valve 98 and a second drainage on-off valve 99, and a branch pipe 81 having a branch on-off valve 94 is branched from the drainage pipe 73 on the radiator panel 61 side of the drainage on-off valve 98. The branch pipe 81 makes it possible to supply well water or the like via the radiator panel 61 to the cold / hot water pipe 59 arranged inside the wall 41 and the floor surface 29.

Further, the return pipe 85 that returns the well water or the like that has passed through the cold / hot water pipe 59 to the drain pipe 73 is located at the position of the drain pipe 73 that is farther from the radiator panel 61 than the drain on-off valve 98, and the second drain on-off valve 99. It is connected to the drain pipe 73 on the side of the radiator panel 61. Therefore, by closing the drainage on-off valve 98, the well water or the like supplied from the pump 91 to the radiator panel 61 is arranged on the wall body 41 or the floor surface 29 via the branch pipe 81 after passing through the radiator panel 61. It can be sent to the hot and cold water pipe 59. Further, after passing through the cold / hot water pipe 59 arranged on the wall body 41 or the floor surface 29, if the second drainage on-off valve 99 is opened, the water can be discharged to a well or the like via the return pipe 85 and the drainage pipe 73. It is supposed to be.

Then, a return on-off valve 95 is provided on the return pipe 85, a return pipe 87 having a return on-off valve 97 is branched on the cold / hot water pipe 59 side of the return on-off valve 95, and a branch pipe further branched from the drain pipe 73. A supply pipe 83 provided with a supply on-off valve 96 is connected to the cold / hot water pipe 59 side of the branch on-off valve 94 of 81.

Therefore, by closing the branch on-off valve 94 and the return on-off valve 95 and opening the supply on-off valve 96 and the return on-off valve 97, for example, hot water is supplied from the supply pipe 83 to the cold / hot water pipe 59 and passed through the cold / hot water pipe 59. It is also possible to discharge the hot water from the return pipe 87 without sending it to the drain pipe 73.

Further, by supplying the temperature control fluid such as cold water to the cold / hot water pipe 59 from the supply pipe 83 instead of the hot water, the wall is provided with a temperature control fluid different from the well water or the like through the radiator panel 61. While controlling the temperature of the body 41 and the floor surface 29, the temperature control fluid can be discharged from the return pipe 87.

A water supply on-off valve 93 is provided at a position farther from the cold / hot water pipe 59 than the drainage on-off valve 98 of the drainage pipe 73, on the downstream side of the return pipe 85 and on the upstream side of the second drainage on-off valve 99.
