Abstract

The invention relates to an earthen ruins dedicated wind erosion simulation device composed of a wind source processing system, a wind speed measurement system, a wind speed control system and a sand dust filling component. A wind speed measurement module, a wind speed control module and a fan of a wind source processing module are connected together to form a sub assembly; a sand-loading bucket module and a steady flow net, a shrinkage port, a honeycomb and a wind outlet of a wind source processing module are connected together to form a sub assembly. During testing, the two sub assemblies are connected through a wind supply hose pipe. Through simulation of different wind speeds and sand-carrying wind, natural wind and sand storm special weather wind erosion effects are simulated, the destructive effect of earthen building ruins under the action of wind erosion is further researched, a large field test is effectively achieved, and a positive promoting role in scientization and standardization development of earthen ruins protection researches is achieved.

Description

technical field

[0001] The present invention relates to soil site test research to simulate soil wind and sand erosion in northwest arid area, specifically a visually adjustable variable wind speed wind erosion simulation device, which can provide net wind at all levels of wind speed controllable in northwest arid area And the sand-carrying wind. It is mainly used in the field of earthen site protection, and can also be used in related fields such as geotechnical engineering. Background technique

[0002] There are many ancient earth building sites in Xinjiang, Gansu, Ningxia and Shaanxi in Northwest China, and there are various types. Most of the ancient building sites in Northwest China are made of rammed silt, silty clay or sand. Earthen buildings are extremely fragile against wind and sand. Under the influence of long-term natural and human factors, the site ontology has highlighted different types of diseases. Especially under the action of strong wind and sand-carry...
