Problems solved by technology

[0005] In order to achieve the above research, most of the molds for producing standard mechanical test pieces are manually extruded, and the work efficiency is low, and the inventor also found that each mold can only produce standard mechanical test pieces with a single modulus, which cannot be mass-produced Standard mechanical test pieces with full modulus, the applicability of traditional manual production molds is limited

Embodiment 1

[0077] It can make 4 standard mechanical test pieces with a diameter of 50mm and a height of 100mm, 4 pieces of standard mechanical specimens with a diameter of 50mm and a height of 150mm, and 8 pieces of standard mechanical specimens with a diameter of 50mm and 200mm. The specific operations are as follows:

[0078] 1) see figure 2 As shown, the self-tightening bolts are first used to connect the detachable and assembled specimen preparation molds into a whole, and then the detachable and assembled specimen preparation molds are fixed on the bottom plate through guide rails to complete the bottom plate assembly.

[0079] 2) Filling the rock and soil mass, filling the specified amount of rock and soil mass into the hole of the detachable and assembled specimen preparation mold according to the requirements.

[0080] 3) Assemble the top plate, and the presser is fixed on the top plate through the pin. At this time, the presser is arranged according to the number of standard me...

Embodiment 2

[0085] This time, 16 standard mechanical test pieces with a diameter of 50mm and a height of 150mm were produced. The specific operations are as follows:

[0086] 1) Reference figure 2 As shown, the self-tightening bolts are first used to connect the detachable and assembled specimen preparation molds into a whole, and then the detachable and assembled specimen preparation molds are fixed on the bottom plate through slide rails to complete the bottom plate assembly.

[0087] 2) Filling the rock and soil mass, filling the specified amount of rock and soil mass into the cavity of the detachable and assembled specimen preparation mold according to the requirements.

[0088] 3) Assemble the top plate, and the presser is fixed on the top plate through the pin. At this time, the modulus of the presser is arranged according to the number of standard mechanical test pieces of different modulus, and 16 standard mechanical test pieces with a diameter of 50 mm and a height of 150 mm can...

Abstract

The invention discloses a test device and method capable of preparing multiple test pieces in batches, solves problems that in the prior art, test pieces are manually manufactured, and only test pieces of a single size can be manufactured, and has the beneficial effects that operation is convenient, and test pieces of different sizes can be manufactured at the same time. The test device capable ofpreparing the multiple test pieces in batches comprises a supporting frame, wherein the supporting frame supports a plurality of mold presses, detachable test piece preparation molds are arranged below the mold presses, and the distances between the bottom ends of the mold presses and the test piece preparation molds are adjustable; the test piece preparation mold is provided with a plurality ofholes for filling rock-soil bodies, and at least one of the mold pressing device and the test piece preparation mold can do reciprocating rectilinear motion relative to the other one, so the mold pressing device is fed into the holes of the test piece preparation mold.

Description

technical field [0001] The invention relates to the field of geotechnical tests, in particular to a test device and method capable of preparing multiple test pieces in batches. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the increasing demand for space from human activities, it is necessary to continue to explore the high altitude underground, especially the exploration of underground space, and the theoretical and technical requirements for geotechnical engineering are constantly improving. In order to better solve geotechnical engineering problems, disaster prevention, and disaster control, it is necessary to conduct surveys and tests, experiments and analysis first, and use soil mechanics, rock mechanics and other theories and methods to conduct systematic research on various projects. Therefore, geotechnical engineering mecha...
