Abstract

The invention relates to a box type load-holding erosion test device which comprises a water tank, a water pressure control system, a water pipe connector, an oil pressure control system and a hydraulic cylinder. The box type load-holding erosion test device is characterized in that the water tank comprises a tank body and a tank cover; a mounting hole is formed in the middle of the tank cover; the hydraulic cylinder adopts a hydraulic cylinder with a single piston rod; the piston rod passes through the mounting hole from the upper part of the tank cover, enters into the tank body and fixes the hydraulic cylinder on the tank cover in a sealing manner; a valve is also arranged on the tank cover; another hydraulic cylinder is arranged on the right lateral wall plate of the water tank; a tankbody water inlet opening is formed on the left lateral wall plate of the tank body and communicates with the water pressure control system via the water pipe connector; a window hole is formed in themiddle of the bottom plate of the tank body; a lug boss and a rubber seal gasket are arranged on the window hole; the oil pressure control system controls the movement and the pressure of a piston inthe hydraulic cylinder; and the left end of the piston rod is movably connected with a pressing plate. The box type load-holding erosion test device is used for carrying out durability tests on reinforced concrete members under saline-alkali erosion and ballast multi-coupling.

Description

technical field [0001] The invention relates to a box-type sustained-load erosion test device, in particular to a sustained-load erosion 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 combined e...
