Self-adjusting visual precise dynamic sounding device

Abstract

The invention discloses a self-adjusting visual precise dynamic sounding device. The device comprises an operating table, and a supporting leg capable of adjusting the height is arranged at the bottomof the operating table; a positioning sleeve is fixedly arranged on the operating table in a sleeved mode, a drop hammer bearing block is arranged in the positioning sleeve in a sleeved mode, a sounding rod is arranged in the center of the drop hammer bearing block in a sleeved mode, a permanent magnet column and a drop hammer column are arranged at the positions, corresponding to upper part of the drop hammer bearing block, of the sounding rod in a sleeving mode, and the permanent magnet column and the drop hammer column are fixedly connected into a whole; the part, corresponding to the lower part of the drop hammer bearing block, of the sounding rod extends out of the positioning sleeve and abuts against the surface of the to-be-measured soil foundation; and the position, located abovethe permanent magnet column, in the positioning sleeve is fixedly provided with a power coil in a sleeving mode. According to the device, the defects that an existing sounding device system can not beperpendicular to a soil body all the time and can not be suitable for various terrains soil bodies are overcome; and meanwhile, according to the device, electromagnetism is adopted as a power source,the impact and the effect of dropping a drop hammer can be adjusted, and high-precision and intelligent outstanding benefits are achieved.

Description

Technical field: [0001] The invention relates to the field of dynamic sounding, and mainly relates to a self-adjusting visible and precise dynamic sounding device. Background technique: [0002] Dynamic penetration test is an in-situ test method commonly used in geotechnical engineering investigation, which is developed on the basis of static penetration test. For coarse-grained soil or foundation soil with high penetration resistance, power is needed to easily penetrate the probe. Since the late 1950s, dynamic penetration testing has been used to drive a probe of a certain size and shape into the soil. According to the difficulty of penetration, that is, the number of penetration hammers, the name of the soil layer and its engineering properties are determined. According to the weight of the drop hammer column and the lifting height, the mass of the commonly used drop hammer column in China is 10kg, 63.5kg and 120kg, which are called light, heavy and super heavy-duty dynam...
