Embodiment 1

[0048] like figure 1 , 8 As shown, the device as a whole includes four steel pipes 9 with a diameter of 5 cm. A groove 10 with a width of 1 cm, a depth of 1 cm, and a length of 30 cm is provided in the middle of the steel pipes, so that the subsequent plate rises along the grooves through the pulley, and the bottom of the steel pipes has threads 26 The top of the steel pipe is provided with a plurality of fixed circular holes 18 with a diameter of 2 cm along its length direction. The four steel pipes are all parallel to each other and vertically arranged. The four steel pipes are connected with a bottom plate 1, a plate 3, Plate two 5 and top plate 7.

[0049] like Image 6 , the four corners of the base plate are respectively provided with a base plate connecting hole 15 with a diameter of 5cm, the base plate connecting hole has threads, the steel pipe bottom stretches into the base plate connecting hole and is threadedly connected with it, and the base plate is provided wi...

Abstract

The invention discloses a triaxial sample batch manufacturing device and method capable of carrying out dry-wet cycle, the triaxial sample batch manufacturing device at least comprises four steel pipes, a bottom plate is fixedly connected to the steel pipes, and an electric jack is arranged on the bottom plate; a first plate is slidably connected to the steel pipes, the first plate is fixedly connected with a pressure applying device, the second plate is fixedly connected to the steel pipes, the second plate is connected with a plurality of soil making molds, the top plate is fixedly connected to the steel pipes, a plurality of dry-wet circulation molds are arranged on the top plate, an inserting groove is formed in one side of the top plate, and after an inserting plate is connected into the inserting groove, the dry-wet circulation molds are not communicated with the soil making molds; and the top ends of the dry-wet circulation mold sextend inwards and are connected with water pipes; According to the invention, the electric jack is used for pressing a soil body into the soil preparation mold at one time, after sample preparation is completed, the electric jack can push the samples into the visual dry-wet circulation molds for a dry-wet circulation test, and the water content change, fracture development and the like of the sample can be monitored through the pressure sensor; and automatic sample preparation, demolding and dry-wet circulation test can be realized.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering geotechnical tests, and in particular relates to a device and method for batch production of triaxial samples capable of performing dry-wet cycles. Background technique [0002] Although the operation of the triaxial test is simple and fast, the preparation of the triaxial sample requires a lot of time for the test personnel. If a conventional soil maker is used for sample preparation, followed by a dry-wet cycle test, it will greatly delay the scientific research test. Therefore, it is necessary to develop a sample preparation device after batch dry-wet cycles. [0003] Although there are soil making devices that can make samples in batches and demoulding, such as the publication number is CN 111781050 A, the title of invention is a sample demoulding device for soil remodeling samples and its use method. The uniformity and density of the obtained samples can be well controlled, ...
