A water head difference penetration test device under the condition of sustained load

Abstract

The present invention is a water head difference penetration test device under load conditions, comprising a water tank, a water pressure control system, a water pipe joint, an oil pressure control system, and a hydraulic cylinder; the water tank includes a box body and a box cover; A valve is provided; the horizontal wall plate at the left end of the box body is provided with a water pipe joint to communicate with the hydraulic control system; the longitudinal left side of the box body, the inside of the front and rear wall plates are symmetrically fixedly connected with at least one For the concave groove, the notches are opposite; a tail plate is inserted between the notches; a mounting hole is provided in the middle of the transverse wall plate at the right end of the box; the piston rod of the hydraulic cylinder passes through the installation from the right end of the outside of the box The hole enters the box body, and the hydraulic cylinder is sealed and fixed on the outside of the horizontal wall plate at the right end of the box body; the oil pressure control system controls the movement and pressure of the piston in the hydraulic cylinder; the left end of the piston rod is movably connected to a pressure plate; In this paper, the durability test of reinforced concrete members under the action of saline-alkali erosion and ballast multi-coupling is carried out.

Description

technical field [0001] The invention relates to a water head difference penetration test device under a sustained load condition, in particular to a concrete component 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. However, in the process of using these buildings, it is found that many buildings have not reached the design service life, but structural damage and durability failure have occurred. [0003] The reason is that most coastal buildings use reinforced concrete structures. Pile foundations in saline-alkali soil will cause premature corrosion and swelling of steel bars in reinforced concrete, which in turn will cause cracks on the concrete surface, resulting in durability failure of reinforced concrete structures. For the durability research of...

[0003] The reason is that most coastal buildings use reinforced concrete structures. Pile foundations in saline-alkali soil will cause premature corrosion and swelling of steel bars in reinforced concrete, which will cause cracks on the concrete surface and cause durability failure of reinforced concrete structures.
