Foundation detecting device and detecting method

Abstract

The invention provides a foundation detecting device and a detecting method; a foundation comprises a foundation soil mass positioned in a container, and a foundation model cast in the foundation soil mass in situ; the detecting device comprises a rain falling system and a liquid collecting system respectively arranged at the top and the bottom of the container, a tension meter connected with the foundation model through a connecting rod, and displacement sensors respectively arranged on the foundation model and the foundation soil mass; the container is manufactured by a high-strength and corrosion-resistance transparent organic glass plate; and clamping grooves deeply embedded in the foundation soil mass and having conical bottoms are symmetrically arranged at the two ends in the container. The technical scheme, provided by the invention, can research the migration condition of ions in a water body of the foundation soil mass under the rail falling condition and the relation between the drawing resistance change of the foundation model and the adhesive strength change of the foundation soil mass.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to a device and a method for detecting the uplift bearing performance of foundation foundation and the chemical composition of foundation soil seepage fluid under simulated rainfall conditions. Background technique [0002] The foundation of transmission lines is different from ordinary geotechnical engineering. It has the characteristics of wide distribution, large span, complex topography and geological conditions. Type and design optimization is of great significance. In recent years, more and more transmission line projects have passed through special soil areas such as loess, red clay, salt swamp soil, and expansive soil. Studies have shown that the bonding strength of the above-mentioned special soils is mainly related to the type and content of cement in the soil, and the dissolution of cement by water is the main reason for the damage of special soil foundations ...

Problems solved by technology

[0003] In recent years, scholars at home and abroad have obtained a lot of results through the "soil column leaching" test. This test is mainly used to analyze the changes of soil permeability, compressibility, and soil strength under rainwater leaching. (Including leaching, immersion, water erosion) There is still a lack of research on the change in the pullout resistance of the foundation model due to the change in the bond strength of the foundation soil, which is related to the lack of relevant testing equipment to analyze this scientific phenomenon.
