Abstract

The invention discloses a multi-split remodeling saturated soil sampling device which relates to the field of soil tests of civil engineering. The structure of the multi-split remodeling saturated soil sampling device is mainly as follows: sample preparation devices are arranged on an iron frame; one end of a steel wire rope is fixed on a left cross rod; the other end of the steel wire rope sequentially penetrates through the iron frame and fixed pulleys of the sample preparation devices and then is connected with the middle end of a long rod, a weight is loaded on a hook, and the hook is connected with the left end of the long rod, so that a structure for performing loading and force transferring on each sample preparation device is formed; a base, a lower water penetrating stone, a soil sample, an upper water penetrating stone, a cover plate, a vertical rod and the cross rod in each sample preparation device are sequentially connected from bottom to top in a sample preparation cylinder so that a structure for a soil sample test is formed. According to the multi-split remodeling saturated soil sampling device, a vertical pressure is applied to thin mud in each sample preparation device by using a lever principle and fixed pulley blocks, the testing time is saved for the soil test with multiple variables and long sample preparation period; one set of loading system is only required, the cost is effectively cost, and a relatively good economic practicability is achieved.

Description

technical field [0001] The invention relates to the field of civil engineering geotechnical tests, in particular to a multi-connected remolded saturated soil sampling device; in particular to a device for preparing saturated remolded fine-grained soil samples, which is suitable for studying the physical and mechanical characteristics of the chemical action of water and soil Test remolded soil sample preparation. Background technique [0002] In engineering practice, a series of indoor tests will be carried out in order to obtain the physical and mechanical parameters of the soil. At present, the soil samples used in indoor experiments can be divided into original soil samples and indoor remodeled soil samples. Although the undisturbed soil sample can truly reflect the original structure of the soil, due to the limitation of sampling technology and the influence of the environment, the test results are not ideal and the dispersion is large. On the contrary, indoor remolded ...
