In infrastructure projects such as highway and bridge construction, housing construction, and pole arrangement, it is necessary to seriously address the major earthwork and foundation quality issues. With the wide application of concrete cast-in-place pile technology, how to drill soil in complex strata with high speed and quality, and how to carry out foundation construction in seasonally frozen soil areas,  earth augers are the soil drilling machines used in this industry.

According to the usage of drilling machines and tools, Liaoning Road Construction Machinery Factory has analyzed and compared various aspects such as geological conditions, pile hole specifications, average work efficiency, work cycle, wall protection, ballast removal, and cost, and developed a reverse circulation bridge  earth augers.

Main features: Good adaptability, it is possible to drill underground pile holes with apertures of various specifications below 1.2 meters from ordinary soil to coarse sand, fine sand, loam, and hard clay layers from shore to water. The drilling depth can reach 50 meters. The drilling speed is fast, and it only takes 8-12 hours to complete a pile hole with an aperture of 90 centimeters and a depth of 36 meters in general soil formations. The drilling is regular and the reaming rate is small. Generally, the hole expansion rate is within 0.5~1.5%. The wall protection method is simple and reliable. Clear water wall protection can be used in general soil layers, while mud wall protection in sand layers does not require special facilities such as mud pools and mud pumps. By observing the slag discharge, it is ideal to master the geological conditions of any drilling depth.

Suitable for gardening, urban greening, slope planting, and pit digging operations, it is a "good helper" for people to return farmland to forests. The machine has the characteristics of small size, lightweight, fast startup, complete structure and function, and good mobility in digging operations, which has attracted the love and attention of agricultural machinery departments everywhere.

Using mechanized conversion of farmland to forests can greatly improve tree planting efficiency and ensure the quality of seedling planting. Portable soil drills have a strong adaptability, not only for planting trees and digging pits, but also for burying piles, columns, exploration, drilling, and other operations in construction sites, geological mines, power transportation, and other departments. Main structural performance Portable pit diggers are available in single or double-person operation models, and the main structure consists of a rack, operating handle, gasoline engine, fuel tank, variable speed clutch, drill, and other parts.

A earth auger with a spiral head (blade tip) at the front end that rotates with a turntable, rotates into the ground, and finally draws out the soil to drill a hole. Frequently loaded on trucks to increase mobility. Tracks can be used on rough terrain.
