What is rammed earth? What is this soil most afraid of?

Tamping earth is not afraid of anything. Rammed soil is a kind of material in ancient traditional architecture, which is to put a gap in a piece of soil.

After compaction, it becomes stronger, the material is close to nature, environmental protection and economy, warm in winter and cool in summer, and the cost is low. It can realize local materials and rammed earth building, also known as adobe building. It has a long history since ancient times. Four or five thousand years ago, smart people in China had built city walls with rammed earth. During the Yin and Shang Dynasties from16th century BC to 1 1 th century BC, there was a mature rammed earth construction technology.

The general method of tamping soil is to tamp soil layer by layer with dry foundation. In ancient times, many laborers needed high-intensity physical labor, ranging from thousands to tens of thousands. In ancient China, only the government and nobles were able to gather so many labors.

Precautions:

1. When the rammed wall is high, it should be used with scaffolding to ensure the safety of construction personnel during the rammed wall construction. During the construction of rammed earth wall, special attention should be paid to the vertical and horizontal control of formwork and each rammed layer.

2. In addition to the foundation compaction of the first layer, the self-weight of the formwork is transferred to the top of the rammed wall at the lower part through the wall-penetrating screw at the lower part. Although the stress section of the screw is small, the density of the newly rammed soil is high, and the self-weight of the formwork is light, which will not damage the newly rammed part at the lower part.

3. When building rammed earth wall buildings, it should be noted that the plane should be arranged neatly, regularly, with simple design, and the facade should have continuous functions. Don't stagger the gate or open the door irregularly to avoid the previous production and living habits in rural areas. Building auxiliary rooms such as pigsty, henhouse and utility room directly on the original building earth wall will not only lead to irregular building plane.
