Problems solved by technology

[0004] In the process of geotechnical engineering exploration and construction, it is often necessary to measure the tightness of rock and soil. The existing measurement methods are complicated to operate, not suitable for carrying out, the measurement accuracy is poor, and it is not applicable to the measurement of various rock and soil densities.

Embodiment 1

[0034] See Figure 1-5 , Geotechnical investigation and test sample density testing system, including sample guiding system, also including weighing system, sample volume detection system and computer data processing system, wherein: the sample guiding system is used to bring the sample into the whole device, Let the sample enter the weighing system and the sample volume detection system in a stable and uniform attitude, which is the guiding part for the sample to enter the test system; the sample guiding system includes a sample conveyor belt 1.

[0035] The use of 20cm conveyor belt, linear transmission method, the advantages of linear transmission: low manufacturing cost, simple linear conveying structure, flexible use, easy to adjust the position of the mechanism; it is driven by an adjustable speed motor, driven by a 2.5cm diameter wheel hub drive device The tight conveyor belt, the middle frame and the supporting rollers form the conveyor belt as the traction and load-bearin...

Embodiment 2

[0043] The other content of this embodiment is the same as that of the first embodiment. The difference is that: the sample volume detection system includes a gate-type laser distance measuring device 2. The two sides of the gate-type laser distance measuring device 2 are provided with laser distance measuring devices 6, and the gate The inner wall of the laser distance measuring device 2 is provided with a laser probe 7.

[0044] Using the portal measurement method, 9 pairs of 18 laser rangefinders 6 are arranged symmetrically and equidistantly on both sides of the portal frame. The number of the laser rangefinder 6 is numbered 1, 3, 5, 7, 9, 11, from bottom to top. 13, 15, 17, numbered from bottom to top on the right are 2, 4, 6, 8, 10, 12, 14, 16, 18, and the top 4 laser rangefinders 6 are numbered from left to right as 19, 20, 21, 22. Use the laser rangefinder 6 to continuously measure the passing sample, measure the section information of the sample, and use special software...

Abstract

The invention relates to the technical field of geotechnical investigation, and discloses a geotechnical investigation test sample density testing system. The testing system comprises a sample guidingsystem, and further comprises a weighing system, a sample volume detecting system and a computer data processing system. The testing system is suitable for geotechnical investigation test sample density testing; the weighing system and the sample volume detecting system are used for measuring weight and volume information of a sample; measuring results are sent to the computer data processing system for calculation; and finally the density of the sample is obtained. The whole device moves through the sample guiding system in a running process, and the sample does not need to be manually moved, so that the use is more convenient; the testing system has the functions of continuous measurement, automatic identification, automatic recording, automatic calculation and automatic storage; and meanwhile, the computer data processing system protects the normal operation of the whole device through a program set in the computer data processing system.

Description

Technical field [0001] The invention relates to the technical field of geotechnical survey, in particular to a test sample density test system for geotechnical survey. Background technique [0002] Rock and soil is a collective term for any kind of rock and soil that make up the earth's crust from the perspective of engineering and construction. Rock and soil can be subdivided into five categories: hard (hard rock), sub-hard (soft rock), weakly connected, loose and unconnected, and with special composition, structure, state and properties. It is customary in China to call the first two types of rocks, and the last three types of soil, collectively referred to as "rock and soil". [0003] Geotechnical engineering survey refers to the activities of ascertaining, analyzing and evaluating the geological and environmental characteristics and geotechnical engineering conditions of the construction site in accordance with the requirements of the construction project, and compiling survey...
