Abstract

The invention discloses an instrument and a method for detecting depths of concrete carbonation and chloride penetration of a pole on service. The instrument comprises an imaging device, a camera device and an operating device, wherein the imaging device comprises a convex lens and a bracket fixedly arranged on the convex lens, the camera device comprises a camera and LEDs (Light Emitting Diode), and the operating device comprises a controller, a display screen and a keyboard. The convex lens is fixedly arranged on the bracket which is connected with the camera device through a stainless steel rod, the camera is located in the circumferential center on one side of the camera device, and the LEDs are circumferentially and uniformly distributed around the camera. The camera device is connected with the controller through a video line, the controller is arranged in a shell, and the display screen and the keyboard are arranged on the surface of the shell and are connected with the controller. The method disclosed by the invention overcomes limitation on existing detection methods of depths of concrete carbonation and chloride penetration of the pole on service, protects continuous capacity of the pole on service, and is suitable for particularity of field detection.

Description

technical field [0001] The invention relates to the technical field of damage assessment and repair of reinforced concrete electric poles of in-service transmission lines, in particular to an instrument and method for detecting concrete carbonation and chloride ion penetration depth of in-service electric poles. Background technique [0002] Carbonation of in-service electric pole concrete is a process of simultaneous physical and chemical actions. Specifically, carbon dioxide in the air dissolves into the pore solution through the capillary pores on the concrete surface to form carbonic acid, and the carbonic acid and Ca(OH) in the hardened cement paste ) 2 and so on to form calcium carbonate. The carbonation of pole concrete is similar to the dehydration process of concrete to a certain extent, and the carbonation product CaCO 3 etc. to block the pores of cement stone and increase the density of cement stone; but for reinforced concrete poles in service, the carbonizatio...
