Description

Technical Field

[0001] The invention relates to the technical field of pile foundation hole detection in construction engineering, in particular to a pile hole verticality and deep hole diameter detection device. Background Art

[0002] In the field of pile foundation construction, precast pile construction usually adopts the method of first spiral drilling and then pile sinking; and in order to ensure the bearing capacity and overall stability of the pile foundation, the verticality of the guide hole needs to be tested.

[0003] The prior art usually uses the following methods to detect the verticality of pile holes:

[0004] 1. Level verticality detection method: set up a reference point and perform horizontal calibration, place the level on the measuring point, and determine the verticality of the pile hole by reading. This detection method has certain defects: first, the level needs to be operated on a stable platform. If the ground at the measuring location is uneven or unstable, it may lead to inaccurate measurement results, requiring additional support and adjustment work; second, the operation of the level requires certain technical experience and meticulous adjustment, which may be difficult for beginners to master. For large-scale construction sites, the complexity of operation and data recording may increase the time and cost of construction; finally, when measuring pile holes with large depths, the level may require additional measurement equipment or technology to ensure the accuracy and reliability of the measurement.

[0005] 2. Plumb line straightness test method: Hang a plumb line in the center of the pile hole, observe the vertical state of the plumb line, and record the deviation to evaluate the verticality of the pile hole. This test method has certain defects: First, the plumb line method is very sensitive to environments with high wind speeds. The wind may cause the plumb line to swing, thus affecting the measurement accuracy; second, in deep pile holes, the plumb line may be greatly bent and stretched, resulting in reduced measurement accuracy, and the length limit of the plumb line also makes it difficult to use effectively in very deep holes; finally, the accuracy of the plumb line method is usually not as good as that of modern measuring equipment, especially in situations where high verticality requirements are required, and it cannot meet the accuracy requirements.

[0006] 3. Laser verticality detection method: install the laser vertical meter and calibrate it; align the laser transmitter with the pile hole; the receiver or ruler detects the deviation of the laser beam and determines the verticality. This detection method has certain defects: first, the correct use of the laser vertical meter requires certain skills and experience, and improper operation may lead to measurement errors; second, the laser vertical meter may be limited in the measurement distance and range in some cases, especially in long-distance or high-precision measurements.
