Title:
DURABILITY TEST SYSTEM FOR REINFORCED CONCRETE STRUCTURE UNDER MARINE MULTI-FACTOR COUPLING EROSION
Document Type and Number:
WIPO Patent Application WO/2024/045324
Kind Code:
A1
Abstract:
A durability test system for a reinforced concrete structure under marine multi-factor coupling erosion, comprising test compartments (1), a middle connecting member (2), sealed compartments (3), a water transport mechanism (4), positioning members (5), lifting/lowering driving parts (6), longitudinal embedding grooves (7), and transverse communication grooves (8). The bottoms of the sealed compartments (3) fit the transverse communication grooves (8), so that the interiors of the transverse communication grooves (8) are in a sealed state. According to the test system, the communication states of the interiors of the transverse communication grooves (8) are controlled, and in the test process of the influences of changes of water level change areas on reinforced concrete specimens (9) on the reinforced concrete specimens (9) in the same corrosive ion environment, the transverse communication grooves are (8) are in communication to ensure the communication between the adjacent test compartments (1), so that environmental aqueous solutions where the reinforced concrete specimens (9) under comparison test are located are always kept consistent, thereby improving the accuracy of test results; moreover, water is injected into the two test compartments (1), and water levels are changed at the same time, so that test preparation and test working processes are reduced, and the uniformity of invariant environmental factors other than variables is improved.
