Problems solved by technology

This light control device overcomes the inaccuracy of the liquid level readings observed by the human eye and the defects that it cannot be measured in real time
However, the above-mentioned device uses a series of light control devices to monitor and collect the permeation liquid level in the whole process, and the number of light control devices required is large and the cost is high.
On the other hand, the amount of data collected by this fully automatic device is large, which is not conducive to subsequent data processing

Embodiment Construction

[0021] Such as figure 1 , figure 2 , image 3 As shown, a specific embodiment of the spaced light control device of the present invention is an improvement to an existing light control device for measuring the seepage level of a soil sample, at least including a soil sample container and a soil sample container inserted into the soil sample container. The permeate tube 5 is a transparent glass tube. It also includes a light source assembly, a sensor module 1 and a pedestal. The pedestal includes a pedestal vertical plate 3 provided with a permeate tube 5 and a pedestal horizontal plate 4 provided with a soil sample container.

[0022] The light source assembly at least includes a linear light source and a modulating signal generator. The sensor module 1 includes at least a plurality of photodetectors, and also includes a preamplifier, a wave detector and a digital signal processor. The linear light source and the light detector are arranged on both sides of the permeate ...

Abstract

The invention discloses an interval type light control device for measuring soil sample penetrating fluid level, which at least comprises a soil sample container, a penetrating fluid pipe inserted in the soil sample container, a light source assembly and a sensor module. The light source assembly at least comprises a linear light source. The sensor module at least comprises a plurality of photodetectors. The linear light source and the photodetectors are oppositely disposed on both sides of the penetrating fluid pipe. The linear light source is arranged along the longitudinal direction of the penetrating fluid pipe. The plurality of the photodetectors are arranged at intervals along the longitudinal direction of the penetrating fluid pipe. On one hand, the light control device requires a smaller number of photodetectors, lowers device cost and improves operational convenience; on the other hand, quantity of acquired data is greatly reduced, work amount of data processing at a later stage is reduced, measuring accuracy also can meet actual engineering requirements, and the light control device has high practical applicability and popularization value in engineering practice.

Description

technical field [0001] The invention relates to the technical field of geotechnical tests, in particular to an optical control device for measuring the seepage liquid level of soil samples. Background technique [0002] In the process of engineering construction, in order to provide analysis of the time factor of foundation consolidation settlement, estimate seepage flow and seepage stability of natural foundation, earth dam, high fill, etc., as well as water supply and drainage design, construction material selection, artificial lowering of water level and For foundation reinforcement design, etc., the permeability measurement data of soil samples has always been an important basic parameter. The measurement of the permeability of the soil sample is mostly done by measuring the height of the transparent liquid level in the transparent glass tube inserted into the soil sample. At present, most of the occasions are to observe the height of the transparent liquid level with th...
