Embodiment 1

[0036] In the prior art, before the measurement of the unconfined compressive strength test sample, it needs to be compacted and demoulded, and the compaction and demoulding operations are completed by different equipment, and the compaction and demoulding are mostly performed by manual hydraulic pressure. The jack consumes a lot of physical strength during operation, and only one sample can be operated at a time, so the work efficiency is low; at the same time, due to the heavy weight of the sample and the mold cylinder, its stability is poor, and deviations are likely to occur during the rising process. Therefore, re-alignment is required; in addition, after the traditional gravel sample is compacted, it is difficult to successfully demould due to the lateral pressure of the mold during demoulding, which is easy to cause damage to the sample.

[0037] In order to solve the problems existing in the prior art that the forming molds for unconfined compressive strength samples of...

Abstract

The invention relates to the technical field of unconfined compressive strength tests, in particular to a recycled water-stabilized macadam unconfined compressive strength sample forming mold which comprises a plurality of sample forming mechanisms and a compaction push-out mechanism. The plurality of sample forming mechanisms are detachably fixed on the compaction push-out mechanism. By arrangingthe multiple sample forming mechanisms and the compaction push-out mechanism, multiple samples can be manufactured at a time, the sample manufacturing time is greatly shortened, one set of samples are formed at a time, the forming pressure and the forming process are the same, and therefore the integrity of each sample is guaranteed, the difference between the samples is reduced, the problem of repeated sample supplementation is avoided; the convenience degree of sample compaction shaping and demolding operation is also improved to a great extent, and thus the difficulty of the sample compaction shaping and demolding operation is reduced, and the sample preparation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of unconfined compressive strength testing, in particular to a molding die for unconfined compressive strength samples of recycled water-stabilized gravel. Background technique [0002] In recent years, the infrastructure construction is still expanding, and the workload of geotechnical engineering and testing is increasing; among them, the unconfined compressive strength test specimens of the Highway Geotechnical Test Regulations (JTG E40—2007) need to be compressed before measurement. However, the sample made in this test is relatively large, and the efficiency of the compaction demoulding process is low. [0003] In the prior art, compaction and demoulding are completed by different equipment, and manual hydraulic jacks are often used for compaction and demoulding, which consumes a lot of physical strength during operation. Only one sample can be operated at a time, and the work efficiency is low. ; At t...
