Description

Technical Field

[0001] The utility model belongs to the field of concrete test piece manufacturing devices, in particular to an integrated test piece manufacturing device for drilling well wall concrete preparation test. Background Art

[0002] At present, the country's demand for energy is increasing day by day. The construction of drilling shaft walls in the western region is urgent, and the region has very high requirements for the durability of concrete. Before building the drilling shaft wall, it is necessary to find the best mix ratio of concrete through relevant civil engineering tests, which puts higher demands on the concrete specimen preparation device. In addition, the drilling shaft wall concrete has the characteristics of early strength, that is, its relevant mechanical performance indicators need to be measured in 3 days, 7 days, 14 days, and 28 days. Therefore, it is necessary to make a considerable number of various specimens to meet the test requirements, and in the process of making and demolding the specimens, the compacting effect of the specimen vibration often determines whether the specimen can meet the test standards.

[0003] At present, concrete specimens are often made in a step-by-step manner. For example, various raw materials of concrete are first mixed in a mixer, and then manually poured into molds in batches and vibrated to obtain various types of standard size specimens. In indoor geotechnical tests, this method of production not only causes a waste of concrete, but also affects the number of specimens produced. In addition, since most vibration tables now require manual pressing of the specimens for vibration, when the vibration table is used for vibration, the mold placed on it will slide with the vibration of the vibration table, affecting the vibration compaction effect, resulting in the test block not being able to correctly reflect the structural strength of the concrete entity. Furthermore, many devices do not take into account the treatment of concrete residues after the specimens are made, which will cause the residues to mix into the next group of concrete and even cause the device to wear, resulting in the subsequent specimens failing to meet the standards required for the test.

[0004] Based on this, there is an urgent need for a concrete specimen production device that can integrate all process flows and effectively improve the vibration compaction effect. Utility Model Content
