Non-destructive testing system and method for pre-stressed concrete beams

Abstract

The present invention belongs to the technical field of non-destructive testing of concrete beams, and discloses a non-destructive testing system and method for pre-stressed concrete beams. The non-destructive testing system comprises: a pre-stress acquisition module, a strength detecting module, an anti-seepage detecting module, a main control module, a crack resistance testing module, and a pre-stress simulation module, a data storage module, and a display module. The method is characterized in that: identification and intelligent analysis are performed on the strength of the concrete through the strength detecting module, and the strength of the concrete structure can be accurately determined; and the pre-stressed tendon and the concrete unit are separately established by the pre-stresssimulation module, so that only specifying the pre-stressing force, the cross section area, the linear expansion coefficient and the elasticity modulus of the pre-stressed tendon can calculate the cooling value applied to the pre-stressed tendon. According to the method provided by the present invention, the actual effect of the pre-stressed tendon is considered, and the pre-stressing effect canbe effectively simulated; and in the complex pre-stressed concrete structure, only the cooling value of the pre-stressed tendon needs to be calculated, and 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...

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
