Description

Pile foundation detects core drilling sampling device Technical Field The utility model relates to the technical field of pile foundation detection, in particular to a drill core sampling device for pile foundation detection. Background The main methods for pile foundation detection include a static load test, a core drilling method, a low-strain method, a high-strain method, a sound wave transmission method and the like, and the core drilling method has the characteristics of science, intuitiveness, practicability and the like, and is widely applied to the detection of the concrete cast-in-place pile. The conditions of pile length, pile body concrete strength, pile bottom sediment thickness and pile body integrity can be obtained through once complete and successful core drilling detection, and the rock-soil characteristics of the pile end bearing layer can be judged or identified. The drill core head at the present stage is erected on the support, and most of the soil around the pile foundation is uneven, so that the drill core is ensured to be stably carried out, the placing position is required to be leveled, but the drill core can be vertical to the ground after being placed, and the drill core is easy to damage. Disclosure of Invention To the not enough of above-mentioned prior art, the technical problem that this patent application will solve is how to provide a be convenient for adjust, ensure the drill core safety, convenient operation's pile foundation detects drill core sampling device. In order to solve the technical problems, the utility model adopts the following technical scheme: The pile foundation detection drill core sampling device comprises a base and a base frame for supporting the base, wherein the base frame comprises a guide supporting structure arranged at four corners of the base, a lifting cylinder is fixedly arranged on the base, a cylinder rod of the lifting cylinder penetrates through the base and is fixedly connected with a mounting plate, a motor is downwards fixedly arranged on the mounting plate through two motor brackets, and an output shaft of the motor is downwards arranged and fixedly provided with a drill bit; the guide support structure comprises guide posts, wherein the guide posts are provided with vertical adjusting assemblies for driving the brackets to move along the vertical direction, the base is fixedly connected with the brackets, and connecting assemblies are further arranged between the adjacent guide posts.
