Problems solved by technology

However, since the reinforced area of ​​the ruins is a tourist attraction, the environmental pollution caused by the slag during the drilling process seriously affects the visits to the ruins and the health of the operators of the drilling rig team. The slag particles splashed by the drill pipe pose a great safety threat to the operation of the drilling rig

Abstract

The invention discloses a dust prevention device special for an earthen archaeological site drilling machine. The dust prevention device is a special-shaped barrel and is fixed by locking a locating support, it is guaranteed that a drill rod operates normally in the barrel in the drilling process, a plurality of dust prevention baffles are arranged in the barrel, the drilling deslagging speed is effectively reduced, dust is effectively prevented from flowing out through a dust prevention closing-in flexible device, rotary flow is formed in the dust prevention device, the speed of large and small drilling deslagging particles is comprehensively reduced through blocking of multiple times, and the large and small drilling deslagging particles flow out of a deslagging opening in a centralized mode. The work environment of a drilling operation platform is improved, the pollution of drilling deslagging on the environment is relieved or eliminated, and the security measures in the implementation process are enhanced. The high-quality drilling technology of a construction field is improved, and the positive effect is achieved in the earthen archaeological site protection and reinforcement project practice.

Description

technical field [0001] The invention relates to the fields of protection experiment research and protection and reinforcement of earth ruins, belongs to a special dust-proof device for drilling rigs of earth ruins, and can also be applied to rock and soil drilling for dust prevention. [0002] Background technique [0003] There are many ancient earth building sites in Xinjiang, Gansu, Ningxia and Shaanxi in Northwest my country, such as Banpo Village in the outskirts of Xi'an, Shaanxi, Dadiwan human settlements in Qin'an County, Gansu, Jiaohe Ancient City and Gaochang Ancient City in Turpan, Xinjiang; Gansu Sites such as the ancient city of Suoyang City in Anxi County; the ruins of the Xixia King's Mausoleum, etc. These earthen building sites have a long history, and some have been listed as world cultural heritage, with high archaeological and historical value. Earthen ruins are architectural ruins based on soil. For thousands of years, severe wind erosion and concentrate...
