Abstract
The present application relates to a quick earth-taking device for compaction detection, which includes a drilling assembly, a sampling assembly, and a sample disk with a first through hole in the middle, a support rod is arranged on the sample disk, and the drilling assembly includes a motor and Rotary drilling bit, the motor is sleeved on the support rod through the first sleeve. The sampling component includes a vertical rod, a horizontal rod and an arc-shaped splint. The vertical rod is connected vertically to the middle of the horizontal rod. There are sliding blocks in the movable wear, the upper and lower surfaces of the horizontal bar are provided with slots connected with the inside, and the second sleeve is movable on the vertical bar, and the second sleeve respectively passes through the slot and the sliding block through the inclined bar. The two ends of the oblique rod are respectively connected to the second sleeve and the slider in rotation. The slider passes through the connecting rod through the slot on the lower surface of the cross bar and is connected with an arc-shaped splint for penetrating into the first through hole. The two arc-shaped splints A clamping space coaxial with the first through hole is formed between the shaped splints. The application has the effect of facilitating the collection of excavated samples.
Description
technical field [0001] The present application relates to the field of compaction degree detection equipment, in particular to a compaction degree detection quick soil fetching device. Background technique [0002] At present, the sand filling method is the main method for measuring the degree of compaction K (porosity n) in many engineering sites. The basic principle of the sand filling method is to use clean and uniform sand with a particle size of 0.30-0.60 mm or 0.25-0.50 mm. Fall freely from a height into a tube or hole with a specified volume, measure the volume of the test hole according to the principle of constant unit weight (that is, use standard sand to replace the aggregate in the test hole), and measure the volume according to the moisture content of the aggregate. Calculate the measured dry density of the sample. [0003] In the related technology, when performing the sand filling test, a person needs to manually dig out the test sampling cylinder with a tool...
