Abstract
A method and designs of underground buildings for any purpose that do not introduce any element above ground level, thus allow agricultural use of the land by any agricultural machine or technology or using the land for recreational park.
Description
- The present invention relates to better use of land and specifically to underground building occupied by humans where the top ground serve for agricultural purposes or recreational parks.
- As world population continues to grow there is a continuous demand for land for housing, offices, industry, agriculture, amuse park and recreational green parks. When human civilization invented agriculture, permanent location inhabitation started where there were lands suitable for agricultural crops. As villages developed into cities, this development came on the expense of fine land highly suitable for agriculture. Today, there are many cities, which are congested with concrete building and far less than desired green areas within the city. Further, continuous demand for new offices building and malls near the cities threaten to diminish the reserves of good land for agricultural use. This causes the authorities to become reluctant to approve new building projects on agricultural land. However, there are positive aspects to build new office buildings, shopping centers, apartment buildings and light industry near existing cities as this can save travel time, air pollution and money to commuters from city to near destinations rather than far destinations.
- Therefore there is a need for innovative technology that will enable dual use of agricultural land so new building can be built without losing agricultural land.
- According to the present invention, there is provided a method and designs of underground buildings for any purpose that do not introduce any element above ground level, thus allow agricultural use of the land by any agricultural machine or technology or using the land for recreational park.

- As world population increases, demand for agricultural products increases, which increases the importance of agricultural lands. However, agricultural lands founds around ever growing cities, which put pressure to build new building on these lands. The location of these lands is an advantage to city residents, which prefer to travel less from home to work and back. Thus, while agricultural lands are important for agricultural crops, high demand for lands near cities for new building projects prevent this use. This justified need to preserve agricultural land, forces entrepreneurs to build new projects far from the city. This causes lengthier travel time from city to new industrial/office parks, increases transportation cost and air pollution. Further, when building new cities, this invention could help in design compact city which make use of underground area for office building while the upper land surface serve for green parks, thus improving the life quality in the city.
- Underground cellars are common knowledge and usually found under existing buildings, however, current underground structures prevents intensive agricultural activity by tractors, combines trucks and air spraying.
- Further, underground building serving as office building while the land above is a green park would create a highly pleasant working area since workers of these building could spent launch breaks in such park.
- It is the aim of this invention to disclose a method and designs, which enable dual use of agricultural land, i.e., intensive agricultural use of the land and high quality human environment for any human activity in underground buildings.

Thus, human need to leave the building using this lift, in emergency case, walks out the lift throughlift door 27, stands on verticallymoveable box 31 and activates it travel upward.Box 31, equipped withelectrical motor 32 that is part of moving mechanism similar to system 200-207 described inFIG. 5 . This moving system lift thebox 31 to about ground level, while thehorizontal cover 34 is raised, by an electric ormanual actuator 36, thus, when thebox 31 top level reaches aboutground level 20, people can leave the box and walk away. Then, thebox 31 returns to bottom position to take additional passengers exiting thelift 26. - This can be done automatically after predetermined time of being in upright position or reacting to direct activation of people in the
lift 26. Routinely, thecover 34, preferable made of steal, is at horizontal position, covering thespace 30. Thecover 34 is installed on verticalconcrete walls 35, which their top surfaces are belowground level 20, about 30 to 50 centimeters. This is a strong structured plate that allows heavy loads such as tractor wheel driving on it without damage to the cover. Thus whencover 34 is in its non-emergency state, i.e., lying horizontally, any agricultural activity in thefield 20 can take place. - In addition emergency stairs shaft are optionally built to allow emergency exit from underground building. Such stair shafts could end below ground level, similar to
shaft 40, so that humans can exit using stairs or ladders. Such stairs shaft, accessed from any floor, is equipped withcover 34 as explained before. Further, emergency evacuation shafts for lift and stairs could end above ground level so that people can reach ground level into a small building having a door that can be opened from inside this small building, thus the evacuees may leave these shafts and go away by foot on the field or park. - Another option to leave such underground building is by using lift or stairs up to the level where
tunnel 14 entered the underground building and leave the building throughtunnel 14 by walking or driving cars. - The ventilation pipes shown in emergency state has remote controlled shutters (128 in
FIG. 2 ) on their openings. Thus, when the pipes are erected, the shutters are open to allow fresh airflow intopipe 25 to the building and used air to flow out throughpipe 24. These two pipes can be installed into one big pipe where their opening face different directions. This ventilation system is another aspect of the invention. - Usually, when not at emergency state, humans enter and leave the buildings through
tunnel 14. Each underground building is preferably equipped withunderground access tunnel 14 or a tunnel connecting a building to theunderground access tunnel 14. Thus, any agricultural activity onfield 20 can take place without interrupting or endangered human activities in the underground building. - Properly designed and built underground building according to the present invention have many advantages over usually above ground buildings:
- Firstly, such buildings are highly earthquake resisting since earthquake horizontal loads are opposed by the
soils 21 that supports the entire vertical walls. This is a very important factor that reduces the underground building structure required strength and cost.
Secondly, underground buildings are not influenced from extreme weather changes thus air-conditioning costs are reduced.
Thirdly, underground building can be built under agricultural lands around the city thus shortening the distance and time to travel from the city, thus saving time, fuel cost and pollution.
Fourthly, since agricultural land is much cheaper than land for office building, the over cost of building and land is low.
Fifthly, since air entering and exiting the building floors are controlled, fire suppression is easier by shutting the fresh air supply to a fire. This issue will become clear after reading, the ventilation system description forFIGS. 2 and 6 . - To increase human ease of prolog stay in under ground building, inner underground building walls may be equipped with natural landscape pictures or Plasma or LCD screens showing natural landscapes or even the landscape of the land on top of the underground building. Further, natural voices of birds and wind and trees noises may be played at low volume to give feeling of nature atmosphere. Also natural scents may be sprayed to give the air nature “touch”. All these features may be activated manually or by a computerized ventilation system.
- Thus, underground building, according to this invention enable prolonged human activity including living, office work, commercial activity and light industry such printing, etc. This is possible since each section of the underground building preferably has its own ventilation system so that fumes are removed without polluting any other sections in the buildings. Any section of the underground building is preferably accessed by underground road and there is preferably, parking places for electrical vehicles near each section so that people can travel miles between many underground buildings.
- The
emergency ventilation pipes electric grid pole 18 provides electricity to the underground building. -
FIG. 2 shows a vertical cross section through underground building. The air ventilation system main components are schematically depicted so that people skilled in the art of ventilation design system can prepare detailed design plan.Fresh air 55 is sucked intopipe 54 equipped with electrical driven, preferably,axial fan 58. Fresh air is flown through underground abouthorizontal pipe 59, towardvertical pipe 60 that runs parallel to the underground building wall 10 (FIG. 1 ). At eachfloor 62, a shorthorizontal pipe 67 a, flows fresh air into the floor. At eachfloor 62 other side, there isair exhaust pipe 67 b, that intakes used air and flows it intoexhaust pipe 69. The usedair 68 is now flowing up invertical pipe 69 toward abouthorizontal exhaust pipe 70 and toward thevertical exhaust pipe 72, which is optionally equipped with electrical driven axial fan that pushes the used air upward to theexit 74. Air exits 67 b preferable equipped with remotely operated shutters that have variable opening thus, a remote control ventilation system can change this shutters opening in order to increase or decrease the air pressure inside the building to prevent radon dissipation from the soil and concrete walls into the building. - The ventilation system optionally equipped with high-pressure air tanks 66. The compressor 64 is connected to the
fresh air pipe 60 and compresses the air into tanks 66. These tanks could hold air at 200 bars or more. In emergency, whenfans shutter 80 to closingposition 82 and opens the high-pressure tanks 66 that supply fresh air to the ventilation system. The high-pressure tanks 66 are connected to the ventilation system through a pipe (not shown), which bypass the compressor. Thus, in emergency, fresh air from the high pressure tanks flow intomain feeding pipe 60 and to eachlevel pipe 67 a. Theshutter 82 prevents fresh air to leave the system throughpipe 59. Theshutter 80 has arotating mechanism 81 that is controlled by the ventilation control system. This mechanism can be build by different designs. One simple mechanism is the one found commercial building electrical shutters. A dc electrical motor that change rotation direction according to electrical current direction. The electrical motor shaft drives a planetary gearbox which decrease the electrical motor number of revolutions by a factor of about 30 thus increasing the out torque that moves theshutter 80 intoposition 82 and vice versa.Stopper 83 blocks the shutter and the electrical current to the motor is stopped. When the emergency situation do not exist the ventilation system return to normal procedure: theshutter 82 is opened to position 80, theelectrical fan 58 pushes fresh air intopipe 59, and compressor 64 pumps air into high pressure tanks 66. - The
intake pipes top closing devices FIG. 4 . The ventilation control system, which is preferably equipped with sniffing sensors that continuously monitors the quality ofair entering pipes - The
emergency pipe 126 is preferably equipped with closingdevice 128—various shapes 128 b and 128 c shown in FIG. 4—so that when thepipe 126 is retracted, theclosing device 128 lies under ground level and it is strong enough to support tractor wheel. Freshair intake pipe 126 is equipped with preferably, electrical axial fan, which is remotely operated by the ventilation control system. In case of electricity supply breakdown, the underground building is equipped withelectrical generator 140 inFIG. 2 , installed in a independent section and powered by fuel or pressurized air pressure engine. Thiselectrical generator 140 receives its air through the ventilation system—pipe 67 a and its exhaust fumes are removed by apipe 67 b topipe 69. - The
access tunnel 14 is preferably serves as used air exhaust channel that receives airflow frompipe 69. This helps remove cars exhaust gases from entering the building throughtunnel 14. In such case, optional axial fans could be installed ontunnel 14 ceiling directing airflow toward theentrance 17. This is another aspect of the invention.FIG. 6 is a horizontal cross section of the ventilation system in each floor. The freshair supply pipe 60 provides air topipe 67 a, which is preferably equipped with electricalaxial fan 67 d. An emergency freshair supply pipe 126, also shown inFIG. 2 , is also connected tohorizontal pipe 67 a that flows fresh air into the building section. Thus, in case airflow inpipe 60 is blocked, the ventilation control system erects pipe 126 n to above ground level, opens its,closing device 128 and turns on its electrical fans. At the same time the ventilation control system shutspipe 59 using mechanism 80-83 to prevent fresh air exiting the system. Used air infloor 62 flows intopipe 67 b and intovertical pipe 69 also shown inFIG. 2 . In case of blockage inpipe 69, the ventilation control system erectsemergency pipe 122, opens itsclosing device 128 to let used air leave the ventilation system. The ventilation floor system preferably equipped withaxial fan 67 d and variable position shutter 67 c thus air pressure infloor 62 can be increased either by increasing the electrical power provided toaxial fan 67 d or by narrowing the exhaust are byshutter 67 b, and vice versa. Theouter wall 10 is shown. - Air condition system, is optionally installed in each floor to warm or cool the air. The air condition system is optionally controlled by the ventilation control system and having manual override.
- The underground building is optionally equipped with water drainage system 90-95. There are locations where underwater are found near ground level surface thus an underground building could be surrounded by water, which could penetrate into the underground building and flow down to the
building bottom 12. To remove this water, apipe 90 which its opening is close to thespace 112 floor, sucks this water by the power ofelectric pump 92 which further pushes the water upward intopipe 92 toward apipe 94 which may flow the water toward sewerage system or water reservoir. -
FIG. 3 is a top view of underground buildings arrangement according to one embodiment of the invention. Vehicles use publicground level road 100 to arrive theseunderground buildings Access road 102 is an exit fromroad 100 toward the undergroundparking lot floors 108. Thecircle road 106 may go down to bottom-floor of the building. Theexit road 104 serves cars leaving the underground parking lot 108 to travel towardroad 100. - The
underground building 200 is preferably divided intosections 112 where each section receives its own fresh air through main fresh air supply pipe 122 (only half is show for purpose of clarity) and section freshinward pipe 126 and used airoutward pipe 129. Thus, each section receives air independently from other sections. Optional electrical axial fans could be installed in each pipe of the ventilation system to increase airflow as shown inFIG. 6 . The used air, flows throughpipe 130 intopipe 136 and into a vertical exhaust pipe 138 (equivalent topipe 73 inFIG. 1 ), which is far from the area that covers the underground building, thus allow intensive agricultural use of the land over this building. The fresh air is entered the ventilation system throughvertical pipe 120, which likepipe 138 is located far from the are above the underground building. From theintake pipe 120, fresh air flows (driven by electrical powered axial fans) towardpipes sections 112. Bothbuildings FIG. 1 , such as retractable-variable height pipes Corridors 150 serve people going from section to section and allow electric vehicles travel between sections. Each building is equipped with lifts that travel between the building floors.Section 110 is optionally parking lot, preferably at each floor, so that people parking their cars inparking lot 108, could use electrical vehicle parking insection 110 and travel to remote sections through corridors 115. These electrical vehicles could belong to a carsharing fleet operated by smart cards. Each section preferably equipped with local cellular network antenna or a cell of cellular system thus enabling occupants in these building to use their cell phones. - The ventilation system is preferably comprises sensors that monitors air quality entered the ventilation system to prevent intake of chemicals, carbon dioxide level and radon level. When chemicals above permitted level are found in the
intake pipe 59 or inside the building, the control system shutsshutter 80 and activates the high pressure backup system to provide fresh air to the under building occupants. Another emergency case is when theelectrical fans pipes pipe 25 is good for breathing, the high-pressure tanks may stop providing their stored air. If however, the outside air contains chemicals, thepipes access road 14. The ventilation control system preferably incorporates smoke and fire sensors. In case of fire, emergency control system identifies the section where fire broke, activates the emergency signs to order people to immediately evacuate the fire zone and close the shutters installed infresh inlet pipes 67 a, that provides fresh air to the fire zone, thus preventing oxygen supply to the fire in the fire zone. These shutters have similar mechanism 80-83 described forFIG. 2 . Similar shutters are preferably installed inexit pipes 67 b thus the control system may closed them partially to regulate the air pressure in each section in order to prevent Radon dissipating into the underground building. -
FIG. 4 is a cross section through retractingvariable ventilation pipe FIG. 2 . The top blocking “hat” 128 comprises a flat, preferably, circular plate shown in its upright position where theholes 129 allows freshatmospheric air 130 to flow into thepipe 127. When blocking element is in its lowest position its top surface blocks thepipe 126 top entrance and holes 129 are blocked by the cylindrical walls ofpipe 126. In routine state of the underground building,pipe 126 is not in use and it is retracted to theposition 122 inFIG. 2 and the hat is in lowest position below ground level thus it do not interfere with agricultural activity. The raising/lowering mechanism comprises an electric motor, which rotates clockwise and anti-clockwise at will combined with planetary gearbox in thesame package 200. Theshaft 202 rotates clockwise or anticlockwise according to desired function of raising or lowering thehat 128. Theshaft 202 has a driving thread along it length andnut 204 having the same thread as theshaft 202, travels up or down alongshaft 202.Nut 204 is firmly connected tocylinder 206. The top edge ofcylinder 206 is connected throughpin 210 to the bottom ofpipe 127. Thus, whenmotor 200 rotate in one direction it pushes thehat 128 upward and when themotor 200 rotates the opposite direction, it pulls thehat 128 downward. Thus the ventilation control system can open or close the entrance ofpipe 126. A similar mechanism 220-229 connected topipe 125 pushespipe 126 upward or pull it downward. It should be noted that the length of movement corresponds to the length of theshafts FIG. 5 . -
FIG. 5 shows the ventilation-retractedpipe 126 equipped with different lifting—retracting mechanism 200-207.Electrical motor 200 is the same as described inFIG. 4 . The t rotating shaft has no threads but a conic 45 degrees gear 202 is installed on its top edge and rotates whit theshaft 201. Thegear 202 is engaged withcorrespondent gear 203 which is also a conic gear which installed onrotatable shaft 206 which is mounted into abearing house 207 which is firmly attached topipe 126. On the shaft 206 astraight gear 205 is installed and rotate withconic gear 206, arectangular gear rack 204, which is firmly attached to thepipe 127 is engaged withgear 205. Thus, whenelectrical motor 200 rotates in one direction it lifts thehat 128 a, and when it lift in the opposite direction, it lowers thehat 128. - The advantages of the mechanisms shown here is that they installed within the pipes thus protected from dirt. The ventilation control system preferably, lifts the bottom pipes first and the topper later so the
hat 128 is lifted when it is well above ground level so that dirt will not enter the pipe as it sucks fresh air into the underground building. - The horizontal cross section of the underground building is optionally made of circular shape to increase the stiffness of the underground building to underground hydrostatic pressure and earthquake resistance. The underground building domes 24 in
FIG. 1 or 110 inFIG. 2 have better strength than flat ceiling because the heavy weight ofsoil 21, crops and trees and heavy vehicles such trucks, combines and tractors. - The underground building could be accessed by underground train (metro) so that a underground train station could be located near such building and underground tunnel connect this station to the underground building.
