A system and method for non-destructive testing of prestressed concrete beams

Abstract

The invention belongs to the technical field of non-destructive testing of concrete beams, and discloses a non-destructive testing system and method for prestressed concrete beams, including: a prestress acquisition module, a strength detection module, an impermeability detection module, a main control module, a crack resistance test Stress simulation module, data storage module, display module. The invention uses the strength detection module to identify and intelligently analyze the concrete strength to accurately judge the strength of the concrete structure; at the same time, the prestressed tendons and concrete units are respectively established through the prestressed simulation module, and only the prestressing force and cross section of the prestressed tendons need to be specified Area, coefficient of linear expansion, and modulus of elasticity can be used to calculate the cooling value applied to the prestressed tendons. This method considers the actual effect of prestressed tendons and can effectively simulate the effect of prestressed. In complex prestressed concrete structures, It only needs to calculate the cooling value of the prestressed tendon, the calculation result is accurate, and the calculation method is efficient.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing of concrete beams, in particular to a system and method for non-destructive testing of prestressed concrete beams. Background technique [0002] Concrete, referred to as "concrete (tóng)": refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of str...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the strength data of the concrete beam cannot be accurately judged when the strength of the existing concrete beam is tested; at the same time, the calculation of the prestress of the concrete beam is inaccurate and the error is large; the existing detection method adopts a single detection method , it is impossible to carry out accurate and comprehensive detection on prestressed concrete beams
