What is the purpose of drilling many holes in the road with a drilling machine?

1 to speed up the drainage.

2. Detection of pavement quality

Technical drilling, also known as control hole, not only controls the bearing stratum, but also controls the underlying stratum, so the exploration depth is deeper than that of ordinary holes.

Extended data:

Drilling engineering has been widely used in many sectors of the national economy. According to the purpose, drilling can be divided into the following categories:

(1) Geological survey or exploration drilling, which is used to understand geological structure and explore or prove mineral reserves;

(2) Hydrogeological drilling to investigate underground hydrogeology;

(three) wells that develop and supplement groundwater resources for industry, agriculture, national defense and life, and have the function of rich hydrogeological data;

(four) engineering geological drilling, for the construction of plant foundation, dam site, reservoir, bridge, road and other basic conditions for engineering geological drilling investigation or verification;

⑤ Oil drilling, oil and gas exploration and development;

⑥ Geothermal drilling, exploration and development of underground hot water and steam resources;

⑦ Drilling holes for engineering foundation construction, that is, drilling holes for foundation piles or pipe piles used to reinforce the foundation of building engineering;

⑧ Develop drilling holes, mine underground brine, dissolve rock salt and sulfur, and burn and gasify underground coal.
