通过对围包散存土堤型土提仓和砖围土心仓基型土堤仓分别在不同压盖方式下进行气密性测试,发现这两种仓型在500 Pa的压力下,其半衰期均在1分31秒~7分45秒之间,达到国家规定的仓房气密性的要求,而且苫篷四周边埋入土内与裸露相比,其气密性更好。
Through the gas-tightness tests on the silt-type earth retaining silos and the brick-soil silos for the silt embankment in different types of capping method, it was found that under the pressure of 500 Pa, Half-life are in 1 minute 31 seconds to 7 minutes and 45 seconds, to meet the requirements of the state barns air tightness, and canopy surrounded by embedded in the soil compared with the bare, the air tightness better.
