Soil sampling device for soil impact experiment in constructional engineering

Abstract

The invention discloses a soil sampling device for a soil impact test in constructional engineering, and relates to the technical field of constructional engineering, the soil sampling device comprises a frame base and a cleaning assembly, the top of the frame base is connected with an external box, a sliding rail is mounted on the inner wall of the external box, a limiting wheel is mounted in the sliding rail, and an auxiliary assembly is mounted on the inner wall of the sliding rail; the driving assembly is mounted in the auxiliary assembly, the sampling assembly is mounted in the driving assembly, and the auxiliary assembly comprises a servo motor, a traveling gear, a rack frame, a traveling frame and a limiting bearing. According to the soil sampling device, the multiple assemblies are arranged in a matched mode, soil can be rapidly drilled out and go deep into the soil, meanwhile, the soil in holes can be taken out through the sampling assembly when the soil is taken out, the soil sampling integrity is guaranteed, the soil can be automatically pushed into the sampling box, the soil sampling process is convenient, and the working efficiency is improved. The cleaning assembly is used for cleaning the sampling assembly, so that the internal cleanliness of the sampling assembly is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a soil extraction device for soil hammering experiments in construction engineering. Background technique [0002] Compaction testing refers to a method of hammering a soil sample to understand the compaction characteristics of the soil. This method is to use different compaction powers (hammer weight × falling distance × hammering times) to hammer soil samples with different water contents, and measure the corresponding dry bulk density, so as to obtain the maximum dry bulk density (generally refers to the accumulation of aggregates). or compact density), optimal water content, and provide the basis for the design and construction of the filling works. The compaction test can be divided into a light compaction test and a heavy compaction test, and soil borrowing testing is required when the compaction test is implemented.

AI Technical Summary

Problems solved by technology

[0003] In the construction projects on the market, the earth-taking devices for soil impact experiments generally use manual rotation to take the soil. The second-time soil-taking process is time-consuming and laborious. The soil is also rotated by the rotating rod. When the drill pipe is turned, the soil will only leak out and cannot collect the soil, resulting in soil damage. Difficulty in collection, which in turn affects the error of test data
