Sealed load-holding etching test device

Abstract

The invention relates to a sealed load-holding etching test device which comprises a water tank, a hydraulic control system, a water pipe head, an oil pressure control system and a hydraulic cylinder;the sealed load-holding etching test device is characterized in that the water tank comprises a tank body and a tank cover; a mounting hole is formed at the center of the tank cover; a single pistonrod hydraulic cylinder is served as the hydraulic cylinder; a piston rod penetrates through the mounting hole from the upper part of the tank cover, enters into the tank body and fixedly seals the hydraulic cylinder on the tank cover; a valve is arranged on the tank cover; another hydraulic cylinder is arranged on the middle part of a right end wallboard of the tank body; a tank water inlet is formed on an upper central position on a left horizontal wallboard of the tank body and is connected with the hydraulic control system through the water pipe head; a window hole is formed on a central position on a base plate of the tank body; a shaft sleeve with a flange A is arranged in the window hole; a support stud and a sealing bag are arranged from exterior to interior between the lower planeof the flange A and the base plate of the tank body. The sealed load-holding etching test device is used for performing durability test on reinforced concrete elements under multiple coupling effectsof salt and alkali corrosion and pressing load.

Description

technical field [0001] The invention relates to a sealed type sustained load erosion test device, in particular to a sustained load corrosion test device for concrete components, belonging to the field of concrete test equipment. Background technique [0002] In recent years, my country has built a large number of reinforced concrete structures in coastal areas to meet the needs of rapid economic development, such as tunnel traffic. Tunnels run through the ground, mountains and even the bottom of rivers and seas, without occupying surface land, shortening driving mileage, relieving traffic pressure, and bringing great convenience to people's lives. As we all know, the lining of the tunnel is reinforced concrete, which bears the formation pressure of the tunnel rock mass, and at the same time, the groundwater also exerts a large seepage pressure on the outside of the reinforced concrete lining. Therefore, the tunnel lining has long been in the "stress field". Under the combi...

Problems solved by technology

[0004] At present, most of the test equipment for concrete components are single-item test devices, which cannot effectively reflect the actual working state of the tunnel lining, that is, high-simulation tests cannot be done
