Are the caves in the mountains damp? Especially winter

No, it won't. An important reason why the cave is warm in winter and cool in summer is that it has a thick "roof". Northern Shaanxi.

On the roof of the cave, pedestrians can walk horses, and even carry heavy vehicles, even if it is a brick kiln and an earth kiln.

The roof should also be covered with a thick layer of soil, so that the cave can be insulated and insulated, just like an air conditioner.

In addition, the roof and wall of the cave can neither absorb heat directly from the atmosphere, nor can it directly dissipate heat into the atmosphere, and only the mouth of the cave can be in direct contact with the outside world. Therefore, the temperature change in the cave always lags behind the temperature change outside, and the temperature difference does not change much.

The temperature of the cave does not change much in winter and summer. It is said to be warm in winter and cool in summer because of its good thermal insulation performance. The cave was dug on the hillside, so it's"roof"with"walls"are quite thick.

When people dig caves, they choose places with relatively hard soil, which is thick and hard"walls"It is not easy to transfer heat. Therefore, the roof and wall of the cave can neither directly absorb heat from the atmosphere, nor can it directly dissipate heat into the atmosphere, only the mouth of the cave is in direct contact with the outside world. Therefore, the temperature change in the cave always lags behind the temperature change outside, and the temperature difference does not change much.

In short, this information is very reasonable, but I still half-believe, because I have not lived in a cave after all, so I really don't know if it will be cold to live in a cave in winter, as far as the current climate of the earth is concerned, in the past, the southern way could not see snow in winter, and now the south will snow before the north, such a chaotic climate, it is difficult to say whether it will be cold to live in a cave.

In winter, the air is quite humid, and when the air cools to a certain extent, some of the water vapor in the air will condense into tiny droplets, which will be suspended in the air layer near the ground. If there is no wind in the mountains, the small droplets of suspended water do not spread easily, and fog is formed. Fog is a small suspended water droplet, light is not easy to penetrate, diffracted and scattered in the air, what we see is a white patch, which is white fog.

The vegetation in the mountains is luxuriant, the air humidity is high, and the moisture is not easy to dissipate after the rain, and the humidity is greater, forming fog, so it is foggy. A little damp.

Living in a cave in the countryside, it is called a down-to-earth atmosphere, and it is warm in winter and cool in summer. However, the effect of health preservation is greater than that of other types of health care. The disadvantage is that it is inconvenient to go up and down, because you have to go uphill when you go out and go downhill when you enter the door.

I have lived in the cave for less than 30 years, and our cave has a history of more than 200 years.

In the past, they lived in caves, and they were pit-type caves. Because hundreds of years before the 80s, we belong to the loess plateau, the groundwater is more than 60 meters deep, and the annual rainfall is scarce, so 98% of the people live in the cave, although the cave is very tiring to dig, but it is in line with the economically underdeveloped society at that time. Until the 70s, my neighbor also invited a group of "workers" from Anhui to "play kilns", the salary was 260 yuan, 500 catties of wheat, 12 people with a flat shoulder to carry the "blue seeds", digging down from the flat ground, near the south place left a "road" of about 45 degrees, the road was repaired with steps, the soil is a load from this road to carry up, generally divided into three sections.

There are two people at the bottom and one person in the middle, but the distance is short, and the distance between the two ends is farther. Under such conditions, it took less than a month to dig a pit kiln with a depth of 8 meters and a size of 40 square meters, and 3 holes with a height of about 3 meters and a width of about 50 meters at the bottom, and a depth of 8 meters were dug underneath. This is also the last "kiln drilling" activity I have ever seen.

Due to the lack of rain in the past, the cave is not as humid as people think, and it maintains a constant temperature all year round. It is also the best way that people came up with in the past when there was no air conditioning, and it was characteristic that it was not hot in summer and not cold in winter. In today's terms, it is energy saving and environmental protection.

Decades have passed, and the cave is gone, leaving only memories of the past, but the cool feeling of the hot summer is still unforgettable.

The caves in the mountains are not damp because the caves are warm in winter and cool in summer, especially in winter. There is generally less precipitation in the three caves, so it is still relatively arid.

Humidity is sure, but it should be more humid in summer, dog days in summer is the ground must return to moisture, winter is too cold, the return of moisture should be a little worse, but it will be very cold, not to live in people.

The shaking in the mountains is damp, especially in winter.

Third, the caves in the mountains are especially supermarkets, which will be dry in winter, and the winter will not be so long.

It depends on the climate and topography.

Not all of them are the same.

But no matter how many people love me, you don't love me, or lonely, in fact, the cruel thing is that I am fascinated by your cruelty, and I smell the smell of early summer....Eat breakfast while walking, good morning, Mu Sauce Beach, Tons of Tin, Plating.

The biggest feature of the cave building is that it is warm in winter and cool in summer, the traditional cave space is a round arch from the appearance, although it is very ordinary, but in the case of monotonous loess as the background, the arc shape is more light and lively, this form from nature, not only embodies the concept of the sky and the round place in the traditional thought.

At the same time, more importantly, the high round arch at the door opening and the high window can make the sunlight further penetrate into the inner side of the cave in winter, so that the solar radiation can be fully utilized, and the internal space is also arched, which increases the vertical space inside, making people feel open and comfortable.

Shaanxi caves are mainly distributed in northern Shaanxi, referring to the cave-style dwellings in Yan'an, Yulin and other places in Shaanxi Province. It is built along the mountains and underground of the Loess Plateau, is a form of cave dwelling in the natural loess, because it has the advantages of warm in winter and cool in summer, does not destroy the ecology, does not occupy fertile land, and saves money economically, etc., and is widely adopted by the local people.

There are many kinds of stone kilns in northern Shaanxi, stone interface earth kilns, and flat stone kilns, and most of the stone and brick kilns are in the cities, while the rural areas are mostly earth kilns or stone interface earth kilns. The main forms are pit kiln, along the cliff kiln, and kiln.

Cave culture

Qingyang, located in the eastern part of Gansu Province on the Loess Plateau, has a mild climate. In ancient times, it was called Beifeng, and it was called Longdong. It has a long history, and "the prosperity of Zhou Dao began from here".

It is the birthplace of Chinese farming culture, and the farming culture and folk culture are even more colorful. Qingyang, which has a long history, has a rich culture that has been accumulated over a long period of time, and to understand the development of caves, it can be traced back to the ancient farming period.

After thousands of years of wind and rain, the cave is like a mother, experiencing the changes of dynasties, watching her land grow, watching the creation and development of farming culture, with profound traces of farming culture, and the development of farming culture has also driven her development. As early as 200,000 years ago, there were already human beings living and reproducing in the land of Qingyang.

It is recommended to make a horizontal vapor barrier.

First of all, cement mortar is mixed with 5% waterproof powder 20mm thick or membrane waterproof layer is used to make it in the wall, higher than the outdoor floor, located in the middle of the indoor layer dense material cushion (such as concrete cushion), and the indoor floor (below 60mm; The vertical moisture-proof layer is generally set on the waterfront surface of the exterior wall, and the cement mortar is mixed with 5% waterproof powder 20mm thick, and then painted with asphalt oil to complete the two-way process.

The cave is an ancient form of residence for the traditional inhabitants of the Loess Plateau in northwest China, and has the advantage of being warm in winter and cool in summer. There are also the following ways to prevent dampness in the cave: you can often put some desiccant in the cave and replace it from time to time, otherwise the desiccant will not be able to play a role in moisture-proof if the water is saturated.

You can buy a professional dehumidifier and put it in the hole, which will also have a moisture-proof effect.

I am doing research on this topic, generally speaking, the general humidity situation can be solved when the internal exhaust fan is added to speed up indoor and outdoor air circulation; For the dampness caused by infiltration, a double-layer design can be adopted, that is, the ceiling design is carried out after the surface is brushed with waterproof materials, and drainage and ventilation openings are set in the middle layer, which can effectively solve the dampness problem inside the cave.

This is basically not a problem, there is little rainfall in northern Shaanxi

The reasons why the cave is warm in winter and cool in summer are:

The biggest feature of the cave building is that it is warm in winter and cool in summer, the traditional cave space is a round arch from the appearance, although it is very ordinary, but in the case of monotonous loess as the background, the arc shape is more light and lively, this form from nature, not only embodies the concept of the sky and the round place in the traditional thought.

At the same time, more importantly, the high round arch at the door opening and the high window can make the sunlight further penetrate into the inner side of the cave in winter, so that the solar radiation can be fully utilized, and the internal space is also arched, which increases the vertical space inside, making people feel open and comfortable.

Excavation method:

After the location of the cave is determined, start digging the foundation, and the foundation referred to by the cave is determined by the type of cave you dig. If there is a ditch in front of the door, you can use a rack car to dig the soil and push it into the ditch, so that it is convenient to throw the soil and it is more labor-saving.

If you want to dig a pit yard, the family with a bad economy or the terrain is not conducive to mechanical construction, you have to rely on manpower to carry it up with a cage basket one by one, which is very hard. In the past, people cultivated Zhuangzi, only to use the slack farm, rainy days to dig and transport soil, get up early and move in the dark.

The above content refers to Encyclopedia - Cave.

You can add an exhaust fan inside to speed up indoor and outdoor air circulation, you can also put some desiccant in the cave and replace it from time to time, and you can also buy a professional dehumidifier to put in the cave. The caves are mainly distributed in northern Shaanxi, China, and the biggest feature is that they are warm in winter and cool in summer.

Cave is the ancient form of residence of the residents on the Loess Plateau in northern China, generally there are cliff caves, sunken caves, free-standing and other forms.

Cave mainly refers to the cave-style dwellings in Yan'an, Yulin and other places in Shaanxi Province, which are warm in winter and cool in summer, do not destroy the ecology, do not occupy fertile land, and save money economically.

In the Loess Plateau area of China, there is generally less rainwater, and a horizontal moisture-proof layer will be built, and the cave will not be very wet.

In fact, the so-called warm in winter and cool in summer is just a feeling, because the cave can keep the indoor temperature constant compared to other houses, it is warm compared to winter, and it is cool compared to summer.

The surface temperature depends on the sun, that is, the direct sunlight is high, and the sun obliquely hits the bottom, so the winter is cold (the sun obliquely hits the ground in winter), and the summer is hot (the sun is relatively direct to the ground in summer), which also explains why spring, summer, autumn and winter are not the same.

The underground temperature can be relatively kept at a constant temperature deep from the ground, and the cave is covered with thick soil all around, so it is very close to the underground temperature. In summer, when the temperature is high, the underground temperature is lower than the surface temperature, so the cave is cooler, and in winter, the ground is frozen and snowy, and the underground temperature is much higher than the surface temperature, so the cave is much warmer.

Notes:

To say that the cave has a feeling of being warm in winter and cool in summer, it does not mean that it can really make the temperature inside high in winter and low in summer. It's just because of its special geographical location and special structure that there is a temperature difference between the inside and outside of the cave, and this temperature difference gives people the feeling that it is warm in winter and cool in summer. Next, let's talk about the special geographical location and special structure of the cave.

Except for the door, all the other sides of the cave are covered with a thick layer of soil. This thick layer of soil can act as an insulating layer. In the summer, it is difficult for heat to enter the cave, and in winter, it is difficult to escape the heat from the cave.

This layer of soil becomes a natural insulation. This is the same as the adobe houses in the countryside in the past.

1. The cave is excavated under the thick loess layer, which is round arch-shaped, simple and easy to repair, save materials and materials, and is sturdy and durable, warm in winter and cool in summer, very suitable for living.

2. The reason why the cave can be warm in winter and cool in summer is because it has a thick roof and narrow doors and windows.

The thick roof blocks the heat from running out in the winter and the heat coming in in the summer, and the narrow doors and windows reduce the contact with the outside world, so that the temperature difference of the cave lags behind the outside world, and the change is not much, just like an air conditioner.

There are many reasons why the cave is warm in winter and cool in summer.

Thick walls and roofs, as well as relatively narrow doors and windows, thick walls and roofs can effectively block heat from entering the house in the hot summer, and narrow doors and windows play an important auxiliary role;

The roof and wall of the cave can neither absorb heat directly from the atmosphere, nor can it directly dissipate heat into the atmosphere, only the entrance of the cave is in direct contact with the outside world. The temperature change in the cave always lags behind the temperature change of the outside world, and the temperature difference does not change much;

In the cold winter, it is also due to the comprehensive effect of walls, roofs, doors and windows, so that the heat in the cave is not easy to leak out, compared with the traditional house, it can naturally be called warm in winter and cool in summer.

Similar to a thermos pot, the heat insulation effect is good, the heat cannot come in in summer, the cold air cannot enter in winter, and the temperature inside is basically constant.

In the summer, the heat does not come in, and in the winter, the air conditioning does not come in.

It's time to make a waterproof layer. If your cave itself is already made of concrete walls and floors, then you can do this to waterproof. Clean the base surface.

First paint a layer of cement-based permeable crystalline waterproof coating, and then do a layer of SP waterproof, moisture-proof, anti-condensation, mildew-proof and salt-proof mortar outside the cement base, the current foreign materials are better than the domestic ones, and then properly ventilate in dry weather, use a dehumidifier in humid weather, it is very effective, some troops' ammunition depots, submarine depots are doing this. I can show you an example.
