China News Service, Xi'an, January 17 (Reporter Alina) The reporter learned from the Shaanxi Cultural Relics Department on the 17th that archaeologists found a water system at the Qin Xianyang city site. Along the line, there are large and irregular still water silt accumulations similar to lakes.
Combined with archaeological data, it is judged that the eastern waters are the Lanchi recorded in the literature.
Through many years of archaeological excavations, the overall layout of the northern area of the Qin Xianyang city site has gradually become clear. Its palaces, offices, and Guos are divided into columns. The artificial trenches are combined with natural environments such as water systems and terraces to distinguish the boundaries of each functional area and form defense facilities. .
Archaeologists discovered the remains of a 9-kilometer-long water system intermittently distributed from east to west. Along the line, there are three irregular large areas of still water silt accumulation similar to lakes.
In 2020, the easternmost deposit will be explored and tested. Its area will reach 360,000 square meters. The average thickness of the silt deposit is 3.5 to 4 meters. The two test excavation sites have discovered the phenomenon of broken silt deposits in the Han Dynasty or later. It proves that the waters were formed no later than the Han Dynasty.
Based on the surrounding archaeological data, it is determined that the eastern waters are the Lanchi recorded in the literature.
According to records, the Lanchi was a pond built by Emperor Qin Shihuang to divert water, and a palace was built on the north side of the pond, called "Lanchi Palace", which was destroyed and abandoned at the end of the Qin Dynasty.
And this whole east-west intermittent water system should be formed by local artificial ditches connecting natural lakes and marshes, which may correspond to the long ponds recorded in the Han Dynasty documents.
It is an important water conservancy facility in Qin Xianyang city, and it also serves as another important dividing line between the palace official district and Guo district.
Archaeological discoveries show that buildings in the palace official office area of the Qin Xianyang City are densely distributed, with an existing area of about 5 million square meters.
A 50-meter-wide road was found in the west, north, and south of the palace official office area, two horizontally and one vertical, forming a trunk road network.
The southern road is north-south, and the north-south extension connects the Chuchengmen Bridge and the palace building site No. 6 respectively.
The No. 6 elevated platform still has a rammed earth platform above the existing surface. The height from the Qin Dynasty ground to the top of the existing platform is 11.3 meters. The top structure is completely exposed. Curved-shaped walls and pilasters, steps and slope passages, and painted Zhu ground are found And so on, the top restoration area is about 1,000 square meters, which meets the conditions of the government hall.
