1, super front drill:

Belonging to construction survey. When the foundation pile is dug into the bearing stratum, it is a kind of exploration drilling survey to check whether there are weak interlayer, cavity and other adverse geological effects in the range of not less than 5 meters below the bearing stratum of BenQ pile.

2. Geological exploration:

Geological exploration methods such as mapping, geophysical exploration, geochemical exploration, drilling, pit exploration, sampling and testing, and geological remote sensing are used to investigate and study the geological conditions such as rocks, stratigraphic structure, minerals, groundwater and landforms in a certain area.

Second, the application fields are different:

1, super front drill:

Super front drill is mainly used in buildings.

2. Geological exploration:

The application field of geological exploration is wider than before drilling, including deeper geographical environment investigation.

Extended data

Pre-drilling is mainly aimed at foundation piles in karst areas. Before the pile is completed, the bedrock at the bottom of the pile is inspected by drilling, which is basically a large pile with one hole and one pile. Generally, after the pile design drawings come out, the pile is dug in place and before pouring concrete. General strata can be surveyed at selected points, and it is best to survey each pile once in karst areas.

Geological exploration also includes regional geological survey, marine geological survey, geothermal survey and geothermal field exploration, seismic geological survey and environmental geological survey of various scales. Geological exploration must be based on geological observation and research, according to the requirements of the task, in line with the principle of obtaining more and better geological results in a shorter time and less workload, and choose the necessary technical means or methods.
