Abstract

The invention relates to the technical field of geotechnical engineering investigation, discloses a portable sandy soil classification and identification device, and aims to solve the problem that theparticle size of sandy soil is difficult to accurately judge in a field environment. The device comprises a measuring cylinder, which is matched with screening cylinders of different specifications,wherein all the screening cylinders are detachably installed in the measuring cylinder in a using process, scales for metering are arranged on the lower end surface of the measuring cylinder, each screening cylinder comprises an inner pipe body, and screening holes corresponding to the screening cylinders in specification are formed in the pipe face of each inner pipe body. The device is suitablefor rock-soil particle size investigation.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering investigation, in particular to a portable sand classification and identification device. Background technique [0002] With the development of the economy and the continuous improvement of the level of industrialization, the construction of various projects is in the ascendant in our country. Among them, the geotechnical engineering survey is a method to identify, analyze and evaluate the geological and environmental characteristics of the construction site and geotechnical engineering according to the requirements of the construction project. Conditions and the preparation of survey documents are playing an increasingly important role in the preliminary basic work in the entire project construction activities. [0003] At present, in the geotechnical engineering survey specifications, the mass of particles with a particle size greater than 2mm does not exceed 50% of the total ma...
