Comprehensive testing device

Abstract

The invention discloses a comprehensive testing device. The comprehensive testing device comprises a water tank, a water pressure control system, a water pipe connector, an oil pressure control systemand a hydraulic cylinder. The comprehensive testing device is characterized in that the water tank comprises a tank body and a tank cover, and an installing hole is arranged in the center of the tankcover; the hydraulic cylinder is a single-piston-rod hydraulic cylinder; a piston rod penetrates through the installing hole from the upper part of the tank cover to enter the tank body, and the hydraulic cylinder is sealed and fixed on the tank cover; a valve is also arranged on the tank cover; the middle part of a wall board at the right end of the tank body is also provided with a hydraulic cylinder; a transverse wall board at the left end of the tank body is provided with a tank body inlet opening in the upper center, and the tank body inlet opening is communicated with the water pressurecontrol system through the water pipe connector; a window hole is arranged in the center of a bottom plate of the tank body; a shaft sleeve with a flange A is arranged in the window hole; and a supporting stud and a sealing bag are arranged between the lower plane of the flange A and the bottom plate of the tank body from outside to inside. The comprehensive testing device is used for performingdurability tests under the salt-alkali corrosion and resultant force ballast multi-coupling action on reinforced concrete members.

Description

technical field [0001] The invention relates to a comprehensive test device, in particular to a concrete member sustained load erosion test device, which belongs 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 combined effect of the "seepage ...

AI Technical Summary

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
