TECHNICAL FIELD

[0002] In the field of construction engineering survey, obtaining accurate soil sample information underground is crucial for evaluating geological conditions and determining engineering foundation design schemes. Traditional drilling methods are diverse, among which the Luoyang shovel drilling is still used in some engineering surveys due to its convenience and certain applicability.

[0003] However, when using the Luoyang shovel for drilling operations, many problems are faced. Due to the lack of effective guiding devices, the shovel body is prone to deviation during soil penetration. This deviation not only leads to non-vertical hole opening, making subsequent drilling work difficult to accurately position the target detection area, but also increases unnecessary soil excavation. A large amount of redundant soil excavation not only reduces drilling efficiency and prolongs the engineering survey period. UTILITY MODEL CONTENT

[0012] The technical effects achieved by the drilling device for construction engineering investigation are as follows:

[0013] The drilling device for construction engineering investigation can guide the rod body through the guide pipe, limit the movement path of the shovel body, enable the shovel body to accurately move vertically under the guidance of the guide pipe and the rod body, thereby opening a vertical hole on the ground, reducing the deflection of the shovel body when opening a hole on the ground, reducing the amount of excavated earth, and enabling the shovel body to quickly enter the detection area underground to detect the soil sample in the underground detection area.
