The Qingming Festival, also known as the Tower Festival, Xingqing Festival, March Festival, and Ancestor Festival, is a festival in the middle and late period of the Spring Festival. Qingming has two connotations of nature and humanities. It is not only a natural sun spot, but also a traditional festival.
Qingming Festival is the festival of ancestor worship of the Chinese nation. This is a traditional cultural festival that respects ancestors and pursues them carefully. The Qingming Festival embodies the national spirit, inherits the sacrifice culture of Chinese civilization, and expresses the moral feelings of people respecting ancestors and inheriting stories. Ching Ming Festival has a long history. It originated from the ancient Spring and Autumn Festivals. The ancient Ganzi calendar provided prerequisites for the formation of festivals. Ancestral belief and sacrifice culture were important factors in the formation of ancestral sacrifice rituals and customs during the Qingming period. Qingming Festival has a long history and is the synthesis and sublimation of traditional Spring Festival customs. The Qingming Festival is one of the twenty-four special festivals in the Ganzi calendar, which changes seasonally. At this time, everything was clean and tidy, and the earth showed a scene of spring and light. Now is a good time for outings (spring trip) and Qingming (sacrifice).
When Zhaoyuan, Jimo, Lintong, Linqing of Shandong Province sweeped the tomb in the Qing Dynasty, they should add new soil to the tomb. This is said to be for the ancestors to build houses to avoid summer rain seepage. The ancestral tombs of Weihai, Qixia, Huangxian, and other places are sacrificed throughout the country. After the sacrifices, they eat steamed buns and dishes together, which are called "room dishes" or "tour houses". The custom of "cockfighting" in the Northern and Southern Dynasties was preserved in the northern part of Shandong. Children in Binxian, on this day, boiled eggs are on top of each other, whose egg is broken first, and who is the loser. During the Qingming Festival, Qishan, Boshan and other places cooked a pot of millet for a full meal, which was called "rice cow". There is a saying: "A thousand words, a light meal."
The above explained the Qingming Festival culture and how the Shandong side treats this festival. Below we enter the topic, we all know that corrugated pipe is a kind of polyethylene, which is processed by extrusion and special molding process. It is a new type of lightweight pipe with smooth inner wall and closed corrugated outer wall. It has good performance and high quality and is suitable for various projects. It is widely used in municipal sewage and drainage, farmland / garden drainage and irrigation, buried drainage outside buildings, mines, Ventilation and drainage for tunnels, protective covers for communication cables and optical cables, drainage for various roads and stadiums. What about the products produced by the corrugated pipe production line ? Let me introduce you:
The corrugated pipe produced by the corrugated pipe production line can be widely used for drainage and water permeability under light load conditions such as golf courses and sports fields; interior decoration wire sleeves; automotive wire sleeves; prestressed anchor cable sleeves; air conditioner drainage pipes.
Features of bellows production line:
• Production line pipe size φ4-58mm.
• Bellows forming machine is closed structure and can provide vacuum forming.
• The forming module moves back and forth in an integrally closed forming tunnel.
• The forming tunnel is a sandwich design, and the module is forcedly cooled by cooling water uniformly.
• The molding die is made of hard alloy steel, which is resistant to wear and corrosion. The molding modules are not connected to each other, so the time for changing specifications is shortened.
• Extrusion dies and cladding dies for single-wall and double-wall flexible pipes are available.
