According to an operation method of the high-low temperature environment device for the mechanical property test of the concrete test block, the funnel collecting box is vertically arranged and used for containing the concrete test block subjected to the test; the high-low temperature environment box is horizontally arranged, an upper pressing block and a lower pressing block which penetrate through the high-low temperature environment box are arranged on the upper side and the lower side of a front end of the high-low temperature environment box, the top of the upper pressing block is connected to the loading testing machine, and the bottom of the lower pressing block is arranged on the ground; the high and low temperature environment device further comprises a movable feeding system, the movable feeding system comprises a test block base plate and a push rod, the transverse test block base plate is arranged on the bottom side in the high and low temperature environment box, the push rod is arranged at the tail of the test block base plate, the push rod penetrates through the right side of the high and low temperature environment box and extends out, and the push rod can freely move left and right. Concrete test blocks can be replaced through the movable push rod, tests of a plurality of concrete test blocks can be completed in a constant-temperature environment, test precision is improved, test efficiency is greatly improved, and resources are saved.
Description
technical field [0001] The invention relates to the field of testing the mechanical properties of concrete test blocks and components, in particular to an operating method of a high and low temperature environment device for measuring the mechanical properties of concrete test blocks in an environment of -170°C to +100°C. Background technique [0002] Ultra-low temperature storage tank is a special structure that my country has started to build in recent years. The outer tank wall of the storage tank generally adopts the prestressed concrete structure, and the storage temperature of liquefied natural gas is about -165°C. Properties also change, which in turn affects the overall performance of reinforced concrete. In addition, reinforced concrete structures in severe cold regions and base construction for polar exploration are all in low temperature environments, which put forward higher requirements for the performance of reinforced concrete structures. The performance of ...
