What is a cave digging machine 5, what is a cave digging machine

Most of the traditional caves were excavated by hand, but the modern caves are basically renovated on the basis of the ancestors.

The process of digging a cave is first to dig the foundation: after the direction of the cave is determined, the foundation is dug first, and the foundation referred to by the cave is determined first by the type of cave dug. 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 basket and a load, which is very hard. In the past, people cultivated Zhuangzi, only to use the slack and rainy days to dig and transport soil, get up early and move the dark to work; Squeeze time before and after meals, can bear a burden is a burden, the skin on the shoulders is taken off again and again, and the calluses on the hands grind layer after layer; Often the old and the young are not idle; If this generation can't finish it, the next generation will continue to do it. After the general shape of the foundation is dug, the surface must be repaired and leveled, which is called "scraping the cliff face" by the locals.

If the scraper's eyesight, skill, hand strength and strength are good, they can scrape a wonderful pattern on the loess.

The second is to dig caves. After the foundation is dug and the cliff surface is scraped, the kiln begins. Kiln drilling is to dig out the shape of the cave and transport the soil away.

You can't rush to build a cave, because there is a lot of moisture in the soil and it is easy to collapse. After the kiln is laid, it is followed by the kiln, or called "cutting kiln" and "milling kiln". Starting from the top of the kiln, the arch is removed, and the kiln is scraped and smoothed, so that the kiln is completed.

After the cave is dried, the loess and crushed wheat straw and mud are used for the mud kiln. The mud of the mud kiln is made of dry soil and tendons, and the plane of the mud is smooth and smooth. Wet soil and muddy stickiness are not easy to use.

The mud kiln has at least two layers of mud, one layer of coarse mud, one layer of fine mud, and some of which have three layers of mud. After living for a long time in the future, the kiln wall is blackened, and you can mud again.

The third step is to tie gables and install doors and windows. After the kiln mud is finished, then use the soil pendant to tie the gable, install doors and windows, generally the high place on the door is a high window, and the door is parallel to a low window, one door and two windows. The inside of the door is against the window pan kang, and the chimney is set up against the wall outside the door, and the kang is against the window to produce smoke quickly, which is conducive to the cave environment, and is good for the body.

After these steps of excavation and repair, the cave was basically dug.

The caves excavated by people's labor have unique residential value and cultural connotations. It is relatively strong and durable. There are hundreds or even thousands of years of caves in the local area. There is also a folk saying: there are caves that do not leak for a hundred years, and there are no buildings that do not leak for a hundred years. ”

The structure of the cave vault is in line with the principle of mechanics, the top pressure is divided into two, divided to both sides, the center of gravity is stable, the component is balanced, and it has strong stability. In order to live with peace of mind, they often use wooden burdens to support the roof of the kiln in the cave. After several generations, the wind and rain have passed, changed hands several times, tinkered, and still did not lose its residential value.

However, with the development of the economy, more and more caves are abandoned, and there are few excavations, and this excavation method will become less and less known, which has become a trend.

Dear Kiss I'm glad to answer for you, my answer is as follows: The cave digging method is as follows: bending the crack is first to dig the foundation:

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 the dust into the ditch, so that it is convenient to throw the soil and save effort. 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 and rainy days to dig and transport soil, get up early and move the dark to work;
