Problems solved by technology

[0007] The technical problem solved by the present invention is to overcome the existing experimental water tank used for the study of the underwater damage characteristics of dredged soil. The free water in the soil cannot be completely removed, which affects the accuracy of the experiment, reduces the efficiency of the multi-parameter combination experiment, and affects the leveling and compaction of the soil sample when it is re-prepared.

Abstract

The invention discloses a water tank device for a dredged soil underwater experiment. An inner tank made of a water-permeable slabstone is arranged in an outer tank, during water inflow and outflow of a water tank, a soil block sample is prevented from being damaged, the original structure and characteristics of the soil sample are effectively kept, the influences of a testing device on the testing result are lowered, rapid water adding and draining are achieved on the premise of guaranteeing that the soil block sample is not deformed, experiment efficiency is greatly improved in multi-parameter combination type relevant experiments, free water in the soil block sample is completely drained, certain experiment or measurement conditions are achieved, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of research on underwater damage characteristics of dredged soil, and in particular relates to a water tank device for underwater experiments of dredged soil. Background technique [0002] With the continuous development of the dredging industry, more and more researches have been done on dredging technology. Among them, the research on the underwater damage characteristics of dredged soil is a very critical aspect, which involves soil mechanics, hydraulics, material mechanics, etc. Because of the complex category of knowledge, experimental exploration and verification are essential in the research process. Therefore, convenient and suitable experimental tanks are very important for research. [0003] At present, during the use of the existing experimental water tanks, the following problems often occur, [0004] (1) The water flow in and out of the water tank will have a scouring effect on the soil sample,...
