Salt-resistant method and equipment for underground structures and underground salt-resistant granary

Abstract

A salt-resisting method for an underground structure includes constructing an underground moisture-preventing structure, arranging a revetment interface on the internal surface of the structure, allowing the revetment interface and the internal surface of the structure to form an enclosed space. The enclosed space communicates with a negative pressure source. More than one drinking-water pipes are arranged on the bottom of the external surface of the structure, and water is poured to the external surface of the structure to form a long-time effective clear water flowing field from top to bottom to isolate possible salt. An underground salt-preventing structure is disclosed. A revetment interface is arranged on the internal surface of the structure, and the revetment interface and the internal surface of the structure form an enclosed space. The enclosed space communicates with a negative pressure source. A clean water tank is arranged on the upper edge of the underground moisture-preventing structure, an outer water collecting pool is arranged on the outer bottom of the underground moisture-preventing structure, and a brine suction pipe extending into the outer water collecting pool is provided. Clean water pours to the outer side of the structure and brine is sucked to prevent salt from eroding steel bars. In this way, related structures can reach designed service lifetime.

Description

technical field [0001] The invention relates to a salt-proof method and equipment for underground structures and an underground salt-resistant granary. Background technique [0002] Existing grain warehouses are mostly built on the ground for moisture-proof purposes. In the Yangtze River Delta region, in summer, due to sunlight and far-infrared radiation from ground objects, the temperature of grain in the warehouse gradually rises to 30°C or even higher. Even if a lot of money is spent on installing air conditioners to cool down, due to the poor thermal conductivity of grains, it is difficult to cool down the inventory evenly, resulting in huge investment but little effect. After a summer, the free fatty acid parameters of rice have changed greatly, and the nutrition and taste have obviously deteriorated, and many of them are directly treated as aged grains. There have also been cases where grains were hydrolyzed and rotted due to the formation of condensation when the te...
