Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The present invention as Figure 1 to Figure 4 The shown includes the folio cylinder 1, which is axially divided into the same two parts that can be tightly combined, and is a pad 2 that can move up and down in the folio cylinder 1, and can be set on the folio cylinder 1 column The collar 3 outside the body, the compacting rod 4 that can move up and down in the folio. Block 2 has a height of 20mm and a diameter of 71.5mm, and the open cylinder 1 is made of steel with an inner diameter of 72mm, a thickness of 8.5mm, an outer diameter of 89mm, and a height of 184mm, so as to meet the requirement that the ratio of height to diameter of the prepared test piece is 2.0-2.5 . The folio 1 can be split into two pieces axially and symmetrically, and the joint form of the two pieces is a concave-convex interface, and the size of the concave par...

Abstract

The invention discloses a geotechnical triaxial test specimen split mold and a specimen manufacturing method. The geotechnical triaxial test specimen split mold comprises a split cylinder, a cushion block, a sleeve ring and a compaction rod, wherein the split cylinder is axially divided into two equal parts which are combined tightly; the cushion block can move up and down in the split cylinder; the sleeve ring can sleeve the outer part of a split cylinder body; the compaction rod can move up and down in the split cylinder. The geotechnical triaxial test specimen split mold provided by the invention has the beneficial effects that the geotechnical triaxial test specimen is uniform in compaction, thereby obtaining reliable geotechnical triaxial test data.

Description

technical field [0001] The invention belongs to the technical field of civil engineering equipment, and relates to a split mold for a geotechnical triaxial test specimen, and also relates to a manufacturing method for a geotechnical triaxial test specimen. Background technique [0002] With the improvement of soil mechanics theory and the improvement of science and technology level, geotechnical triaxial test has become a commonly used method to measure the mechanical parameters such as internal friction angle, cohesion force and dynamic modulus of soil. In order to obtain these parameters accurately, a good triaxial test specimen is indispensable. The current test regulations require that the diameter and height of the test piece should meet the requirements of the triaxial instrument for the size of the test piece. The ratio of the height to the diameter of the test piece is usually 2.0 to 2.5. For the disturbed soil test piece, the clay should be compacted in 5 to 8 layer...
