As shown in fig. 1 to 3, the present embodiment provides an apparatus for measuring pile foundation hole depth and hole diameter, which includes a hoisting machine 4, a touch display screen 2, a control box 1, a hole diameter measuring assembly 5, and a measuring hammer 6. A signal transmission line 3 is wound on the winch 4; the touch display screen 2 is arranged on the winch 4; the control box 1 is arranged on the winch 4 and is in signal connection with the touch display screen 2, the signal transmission line 3 penetrates through the control box 1 and can move up and down, and the control box 1 is used for controlling the winch 4 to receive and release the signal transmission line 3 and detecting the lowering length of the signal transmission line 3; the aperture measuring assembly 5 is arranged on the signal transmission line 3 below the control box 1, and the aperture measuring assembly 5 is used for measuring the aperture of the pile foundation; the measuring hammer 6 is arranged on the signal transmission line 3 below the aperture measuring component 5.
The control box 1 is connected with a driving motor of the winch, and the driving motor is in transmission connection with a rope winding shaft of the winch 4 through a conveying belt 7. The driving motor receives the instruction from the touch display screen 2 to control the opening and closing of the winch 4 and drive the winch 4 to rotate forwards or backwards, manual operation is not needed, the difference of pressing force at each time can be avoided, the depth of the measuring hammer 6 sunk into the soil is different, the consistency of the measuring result is better, the manual operation process is omitted, and the workload is reduced.
The top of the control box 1 is provided with a first roller 11 for guiding the signal transmission line 3 into the control box 1, a second roller in rolling contact with the signal transmission line 3 is arranged in the control box 1, the control box 1 is provided with a counter of the second roller and used for measuring the number of rotation turns of the second roller, and the control box 1 can obtain the lowering length of the signal transmission line 3 by multiplying the number of turns and the circumference of the roller and display the lowering length on the touch display screen 2.
And a tension sensor in signal connection with the touch display screen 2 is arranged at the joint of the measuring hammer 6 and the signal transmission line 3, and the tension sensor transmits data to the touch display through the signal transmission line 3.
The utility model measures the tension caused by the measuring hammer 6 in real time through the tension sensor. Whether determine through tensile numerical value that survey hammer 6 reachs the pile foundation bottom to the rotatory number of turns of second gyro wheel of record this moment, and then reach the length of transferring of signal transmission line 3, also be the hole depth.
Assuming that the weight of the measuring hammer 6 is G0, the value of the pulling force F in the air environment0＝G0. When the measuring hammer 6 enters the hole bottom slurry of the pile foundation, the measuring hammer is subjected to buoyancy, and the tension is reduced.
The value of the tensile force is F0＝G0-f0In which the buoyancy is f0＝ρgv
