Tropic of Cancer Sign Tower China Tropic of Cancer Sign Tower.

Shantou Tropic of Cancer Sign Tower is located at the southern foot of Jilong Mountain, Tuolian Street, jinping district, Shantou City, Guangdong Province. The tower was completed on June 20, 1986. It is connected with a monument in Chiayi, Taiwan Province Province in the east and Conghua and Fengkai Pagoda in the west. The exact latitude and longitude of the signboard is: east longitude116 35 ′ 8.78 ″ and north latitude 23 26 ′ 32.49 ″. 1994 1 1 was announced by Shantou Municipal People's Government as a municipal cultural relics protection unit, and 1995 was designated as a patriotic education base. The upper part of the tower is a hollow soil model with a diameter of 5 meters. The sphere is of reinforced concrete structure, and the spherical surface is inlaid with glass mosaics of various colors such as yellow, blue and white, which makes the territory of China very conspicuous and the land and sea are distinct. A stainless steel seamless steel tube with a diameter of 40 cm and a length of 5 meters vertically runs through the center of the sphere, allowing you to peep at the blue sky. The lower part of the tower is supported by a "North"-shaped reinforced concrete column inlaid with polished white marble. The tower foundation is a two-story circular platform with diameters of17.2m and 26m respectively. The platform is paved with granite slabs, and a black marble black line from east to west symbolizes the Tropic of Cancer. The platform fence is one meter high and the iron tower covers an area of more than 200 square meters. The sign tower is novel in design and unique in shape, which organically combines geographical science with visual image. At noon on the summer solstice, there is no shadow on the telephone pole; A glimpse of the sun, the sky is strange, you can explore.

In the east-west direction of the observation deck, warm tropical plants are planted on both sides of the black slate belt marking the Tropic of Cancer. When we set foot on this slate belt, we are between the north temperate zone and the tropical zone, and it seems that we can feel the rotation of the earth, and there is a mystery that spans the two zones. "Looking at the sun from the northern standard" is a true portrayal of the "summer solstice" view of the sun. Every summer solstice (noon on June 22), the sun watchers are very enthusiastic, competing to watch the annual spectacle of "standing on a pole without a shadow" and personally feel the alternating moment of spring and summer.

Many trees and flowers have been planted around the Tropic of Cancer sign tower, and mountaineering roads have been paved. There are Kuafu Pavilion and Denglin Pavilion (named after the myth of Shan Hai Jing) on the top of the mountain, and many poems of mountain climbers are engraved on the stone wall beside the road. When you board the pavilion, you can see the wide water surface of Niu Tianyang in the west and Jilong Mountain in the east.

The names of "Kuafu Pavilion" and "Deng Pavilion" are all related to the sun. There is a touching myth in the ancient book Shan Hai Jing: Kuafu means man. In ancient times, when he encountered drought, he wanted to conquer and chase the sun. He was sweating and thirsty. He drank all the Wei water in the Yellow River and still wanted to drink the water from the sea. He died of thirst on the way before he arrived. Kuafu discarded the rattan and planted it underground, which turned into a dense Deng Lin. Deng Lin is Tao Lin. Shantou Tropic of Cancer Sign Tower is located in our coastal city, and the scenery such as "Kuafu Pavilion" is very consistent with the myth story of Kuafu's pursuit of the sun in Shan Hai Jing. North Standard Peeping Day: refers to the Tropic of Cancer sign tower located 5 kilometers north of Shantou University, built at the waist of Jilong Mountain, with a height of 13.6 meters and a bottom width of 30 meters. Support a globe with a diameter of 5 meters with a "north" bracket. Every summer solstice, when the sun shines directly on the tropic of cancer, you can see the sun shining on the ground from the small hole in the middle of the globe. After a few minutes, things changed. Since then, the sun has gradually moved south. Draw the invisible tropic of cancer as tangible on the ground. With one foot in the temperate zone and one foot in the subtropical zone, you can cross the Tropic of Cancer. There is also a Kuafu Pavilion for people to rest nearby. Standing on the top of the mountain, you can see Niutianyang in the west and the conical volcanic landform of Jilongshan in the east. The Tropic of Cancer is located at the southeast end of Eurasia. Due to the influence of sea breeze, there is abundant precipitation, forming lush tropical monsoon forest and subtropical evergreen broad-leaved forest, which is completely opposite to the whole desert belt. Shantou Tropic of Cancer Sign Tower is located at the easternmost end of this special landscape, which is of great significance in environmental science research. The site selection of the Tropic of Cancer sign tower in Shantou adheres to the following principles: ① the principle of learning; ② The principle of not occupying (occupying less) cultivated land; ③ The principle of convenient transportation; ④ The principle of echoing other tourist attractions; ⑤ Aesthetic principle; 6. Traditional customs and other principles. Architectural features of Shantou Tropic of Cancer Tower: Tiantan tower foundation, a huge earth model is placed on the "North"-shaped tower structure, and the center of the earth model has a pipeline for sunlight to penetrate, which is called "peephole" for observing the direct sunlight from summer to sun. The latitude position of the sign tower of Shantou Tropic of Cancer was accurately measured as 23 26' 32.48 "n in A.D. 1990 65438+ 10/day, and the theoretical value of the Tropic of Cancer was 23 26' 26. 1 3" n.

Speaking of the Tropic of Cancer Tower in Shantou, almost all local people know it. This sign tower has two "North" cement columns, which are located next to G206 National Road. If you drive from Shantou University, you can get there in about 10 minutes. 1985 Shantou Tropic of Cancer Sign Tower was officially started, and the main project was completed one year later. 1988 was announced by Shantou Municipal People's Government as a municipal cultural relics protection unit, and 1995 became a patriotic education base and popular science tourist attraction in Shantou. Over the years, it has attracted countless citizens and tourists from home and abroad to watch it.

After many years, the reporter came here again recently. Because it is a working day, there are almost no tourists around the sign tower, and occasionally only local residents come here for a walk. Sister Lin, who opened a canteen near the sign tower, told reporters that there are not many citizens and tourists who usually visit the sign tower, and many people drive over on weekends. During the visit, the reporter noticed that the supporting facilities around the sign tower of the Tropic of Cancer in Shantou are relatively simple, but from time to time, construction workers can be seen repairing the surrounding public facilities. It turns out that due to road construction and other factors, this sign tower has been in a state of power failure and water stoppage for a long time, and the public toilets cannot be used, which brings inconvenience to the citizens and tourists who come to visit. Recently, the Municipal Bureau of Wenguang organized construction workers to be present and improved the supporting facilities of the sign tower, such as public toilets, management rooms, signs, stair handrails, water and electricity facilities, etc., in order to better serve the citizens and tourists.

It is understood that the tower of Shantou Tropic of Cancer is 13.6 meters high and 30 meters wide at the bottom, which consists of three parts: pedestal, column and soil model. On the coming summer solstice on June 22nd, at noon 12, the sun will shine directly on the tropic of cancer for an instant, and citizens can see the sun shining vertically on the ground through the small hole in the middle of the earth model. This is the astronomical phenomenon that "standing on a pole can't see the shadow". Among the 10 Tropic of Cancer symbol towers in China, the Tropic of Cancer symbol tower in Conghua, Guangdong Province is as high as 30.25m, which is the tallest Tropic of Cancer symbol building in the world.

Located on the hillside of Sanjiazi, Youmapu Village, Taipingchang, Conghua City, it is the tallest and largest landmark tower of the Tropic of Cancer in the world. This tower covers an area of 28 mu. The main part of the tower is a mixed structure of concrete and granite, and the foundation part is an altar. The arrangement of floor stones takes the form of Taoist gossip. The tower is 30.4 meters away from the tower foundation and 23.5 meters high, which is an upright rocket type. The bottom of the tower is spherical, with granite in the middle and carved into a hemispherical outline. A brass column with a diameter of 4 cm is embedded in the center point, and thick copper bars are embedded in the east-west direction to show that the Tropic of Cancer extends from this point to the east-west direction of the earth. The top of the tower is a hollow circular hole with a diameter of 120m, which is supported by a stainless steel cylinder and can be inspected in direct sunlight. Every summer at noon on the solstice (12: 26), the sun will shine directly on the round hole in the ball and project the light spot on the spherical copper column at the bottom of the tower. At this point, there is no figure standing under the tower.

This tower was completed on 1985 17 in February, and was unveiled on 1986 from summer to Sunday. The chronicle of the standing stone of Guangzhou municipal government shows that this place is the dividing line between the tropics and the north temperate zone. The Tropic of Cancer marks the completion of Tower Park and becomes a teaching observation point and tourist attraction. Guiping Tropic of Cancer Sign Tower is located in Guiping Tropic of Cancer Park, which integrates science popularization, culture and entertainment. It is close to Xiao Wen Village, Shizui Town, and 8 kilometers away from Guiping City. It was built after Chiayi and Hualien in Taiwan Province Province, Shantou, Congjiang and Fengkai in Guangdong Province and Mojiang in Yunnan Province. It is the seventh Tropic of Cancer sign tower in China and the first Tropic of Cancer sign tower in Guangxi.

This sign tower is mainly composed of an arched building with a span of 26 meters and a height of 17.2 meters, supporting a sphere with a diameter of 6 meters, which looks like the image of the earth. Every summer at noon on the solstice, the sun will pass through a peephole with a diameter of 16 cm in the center of the sphere and directly hit the map of Guangxi, where Guiping City is located, paved with granite stones on the ground under the signboard, which becomes a magical and spectacular phenomenon of "standing without a shadow". This Tropic of Cancer sign tower is located at the top of Daming Mountain in Wuming County, Nanning, Guangxi. It is not big, but it is of great significance. It was built in Daming Mountain, a natural symbol park. The highest peak of Daming Mountain, Longtou Mountain, is1.760m above sea level, and the total area of Daming Mountain Nature Reserve is about 60,000 hectares. The Tropic of Cancer runs right through the middle of Daming Mountain, which is the largest Tropic of Cancer symbol park in the world.

When the Tropic of Cancer passes through the central part of Daming Mountain forest area, people will be surprised to find that in the tropic of Cancer area of the earth, the endless desert has formed a gray-yellow desert belt. In this barren and arid area, there are still several green areas. Daming Mountain is like a green gem embedded in this area, and it is called the "green pearl" on the Tropic of Cancer. The Tropic of Cancer runs through Penghu, Chiayi, Nantou and Hualien counties in Taiwan Province Province, and Taiwan Province Province has epitaphs on both sides of the island. The west landmark is the Tropic of Cancer Monument in Chiayi, and the east landmark is built in Hualien County. There are two Tropic of Cancer Monuments in Hualien County. The earlier one was built in Wuhe Village, Mizuho Township, and the other is Putin's Tropic of Cancer Monument.

The Tropic of Cancer Monument in Chiayi was built at 1908, that is, in the thirty-fourth year of Guangxu in Qing Dynasty. It is the earliest Tropic of Cancer monument in China.

Putin Tropic of Cancer Sign Tower is located in Putin Village, Fengbin Township, Hualien County. It faces the Pacific Ocean in the east, and it is cylindrical and lighthouse-like, which is quite spectacular. The words "Tropic of Cancer" are engraved on the north and south sides of the sign tower, and there is a longitudinal slit in the middle of the column, through which the Tropic of Cancer is passing. Every summer solstice (around June 22nd), at noon 1 1: 54, the sun shines vertically from above. At this time, we can see the astronomical phenomenon of "standing upright without shadow". From this moment on, the northern hemisphere enters summer. When you step on the stone slab in the center of the tower bottom, one foot is in the tropics and the other foot is in the subtropics (north temperate zone), you will have a different geographical feeling. The Tropic of Cancer runs through Nan 'ao Island. The pleasant climate gives the island a unique temperament, elegant, gentle and mysterious, and the Green Bay is even more unique, and the Tropic of Cancer passes through the territory. There is a crescent bay here, and the golden beach extends along the sea, and the sea and the sky are the same. The Tropic of Cancer Tower is built here-23 26' 38.45 "north latitude and 1 17' 50.89" east longitude. Her appearance makes this bay more charming.

Recently, the reporter came to Green Bay and visited this "gate" on the south China sea in advance. On the construction site, the workers are working under the scorching sun. The natural gate is located in the Youth Olympic Bay Square. Green Bay Plaza covers an area of 33 mu and is about 225 meters long. From west to east, the scenic spots are Qian Fang Square, Ruyin Green Ping and the Tropic of Cancer Sign Tower. At present, the construction of the square and the sign tower is going on at the same time. The main structures of the doorposts and aerial cantilever on both sides of the sign tower have been basically completed, and the spheres are still being made. The platform of the sign tower has been completed, and the external decoration construction is under way. The whole square will strive to complete the construction before the National Day this year. By then, the sea, the beach, the square and the castle peak will be connected in one vein, echoing each other and making people linger.

Zheng Shaowen, the chief designer, told the reporter that the design of the natural gate combines natural phenomena and common sense. After the completion of the sign tower, it will show different momentum from different angles and produce different artistic effects under different light and shadow. The natural gate has a unique design, with a sphere radius of 3.2 1 m, corresponding to March 2 1 of the vernal equinox. The cantilever is 6.22 meters long, corresponding to the summer solstice on June 22; The distance between the doorposts is 9.23 meters, which corresponds to the autumnal equinox on September 23rd. The height from the base to the sphere is12.22m, which corresponds to the winter solstice 65438+February 22nd. Because the natural door is located at the seaside, the objective factors such as salty seawater and strong sea breeze are fully considered in the use of materials, and the dry hanging part of the main stone pillar is made of corrosion-resistant stainless steel.

Li Fang, the project manager of Green Bay Plaza, told the reporter that the biggest difficulty in building the sign tower lies in the fixation of the sphere. The reporter saw that the shape of the whole sphere is similar to the return capsule of the manned space shuttle. In the sphere, the supporting frames are evenly distributed, which ensures the uniformity and stability of the sphere. There is a hollow shaft in the middle diameter of the sphere, which is where the sun will pass during the summer solstice. The workers who make spheres are very serious. They meticulously measure, draw and remember with rulers and pens. In addition, the wind resistance and corrosion resistance of the sign tower are also very important. Li Fang said that at present, there is no problem for the sign tower to resist 12 typhoon, and the materials used also have strong anti-corrosion ability.
