[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. In order to detect the compressive resistance of the pile foundation, a coring machine is needed; the coring machine is mainly used to drill test cores of concrete and asphalt concrete for compression and flexural tests. Publication No. CN218546211U discloses a bridge pile foundation detection coring device, which belongs to the technical field of bridge pile foundation detection, and includes a base, a column is installed on the base, and a lifting seat is provided on the column, a motor is fixedly installed on the lifting seat, and a coring tube is provided at the lower end of the motor, a stabilizing structure is provided on the base, and the stabilizing structure includes a movable plate, a support block and a support bolt, the movable plate is fixedly connected to the support block, and the movable plate is connected to the base. By setting up a stable structure, the device can play a role of stable support when in use, ensuring the stability of the device when in use, avoiding shaking that affects the normal progress of coring, and adopting a protective structure, the lower end of the coring tube can be covered when the device is not in use, avoiding rust on the lower end of the coring tube and affecting the normal progress of subsequent drilling work. At the same time, covering the lower end of the coring tube can avoid injury to the transporting personnel, thereby improving the safety of use. Although the product has better stability when in use and can protect the coring tube, the overall flexibility is reduced. When the coring position needs to be calibrated, the entire device needs to be lifted and moved, which makes the calibration more cumbersome, time-consuming and labor-intensive, reduces work efficiency, and has poor practicality, and needs to be improved.
