Description

Technical Field

[0001] The utility model relates to the field of foundation drilling, in particular to an improved device for foundation drilling. Background Art

[0002] Foundation probing is a soil layer detection construction process, in which a standard diameter steel drill with a marked scale is driven vertically into the foundation soil layer by mechanical or manual means, using a calibrated weight hammer. The number of hammer strikes required for the steel drill to enter the foundation soil layer to be detected is used to detect hidden structures in the soil layer or roughly estimate the allowable bearing capacity of the soil layer.

[0003] The foundation probe is a measuring device used to detect the depth of the foundation. Although the mechanical probe has high accuracy, the equipment is bulky and expensive. Although the manual probe device has low accuracy, the equipment is simple and easy to carry. At present, the manual probe device consists of a pole fixed vertically to the ground, and a heavy hammer acts on the steel drill, repeatedly hitting it, so that the steel drill enters the foundation vertically.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: the current manual drilling device consists of a pole fixed vertically to the ground, and a heavy hammer acts on the steel drill, repeatedly hitting it so that the steel drill enters the foundation vertically. However, in actual operation, drill rods of different lengths need to be used. Due to the different heights of the drill rods, the structure height of the drilling machine itself is high and the center of gravity is biased upward, affecting the measurement accuracy.
