Drilling device for earthen archaeological site

Abstract

The invention discloses a drilling device for an earthen archaeological site. The drilling device is characterized in that a bottom plate is mounted on the upper surface of a slideway through two groups of bottom plate rollers; a pair of round guide rails is fixed on the bottom plate, and a motor mounting plate is mounted on the round guide rails through sliders; a gear motor is fixed on the motor mounting plate; a rotating connector is mounted on an output shaft of the gear motor in a sleeving manner; one end of a connecting sleeve is fixedly connected with the rotating connector through a flange, and the other end of the connecting sleeve is in sleeve joint with one end of a drill rod through threads; the other end of the drill rod is connected with a drill; and the drilling rod, the round guide rails and the slideway are parallel. According to the drilling device for the earthen archaeological site, when a drill tube penetrates into the earthen archaeological site continuously, a drill rod jacket arranged on the drill rod in a sleeving manner goes deep into earth mass with the drill rod and is supported on the earth mass through a drill rod support frame, further, the drill rod jacket can move forwards continuously with the drill rod, so that the drill rod is prevented from shaking in a drilling process, the drilling accuracy is guaranteed, safety and reliability are achieved, and the drilling device has the characteristics of convenience, fastness and high work efficiency.

Description

technical field [0001] The invention relates to the field of protection of ancient earthen ruins, in particular to a drilling device suitable for anchor rod reinforcement of earthen ruins. Background technique [0002] Earthen ruins refer to ancient ruins whose main building material is soil. There are many ancient earthen architectural ruins in Northwest my country, such as the Hanguangmen earthen ruins of the Tang Dynasty city wall in Xi'an, Shaanxi, the Dadiwan human settlement site in Qin'an County, Gansu, and the Western Xia royal mausoleum. Ruins, etc. These earthen building sites have a long history, and some have been listed as world cultural heritage, with high archaeological and historical value. Due to the long history, the soil of ancient earthen sites is loose, low in strength, and large in porosity, and most of them have severe cracks, which eventually lead to collapse and damage. At present, bolt anchoring technology is an important method to strengthen earth...

AI Technical Summary

Problems solved by technology

[0005] Although there are many rock bolt rigs, there is no research on the device for rock bolt drilling in earthen ruins

Therefore, most of the existing common methods of anchoring and drilling in the field of earth relics protection are still manual digging. The inner wall of the hole excavated by this method is rough, the inner diameter of the hole is irregular, and the opening of the hole is expanded, which will cause great damage to the surface of the earthen relics. , and the digging rate is extremely low, labor-intensive and time-consuming

However, it is obviously difficult for the existing technology to meet the requirements for the anchor drilling of large-scale soil sites in the arid and semi-arid areas of Northwest China.
